Background Art

As a key technology of the ^sixth generation mobile communication technology (6G), perception technology can be combined with existing communication technologies to achieve the purpose of auxiliary communication. In a communication system that supports perception technology, how to transmit perception information, such as perception requests, has become an urgent problem to be solved.

Summary of the invention

In order to solve the above technical problems, the embodiments of the present application provide a communication method, a communication device and a storage medium to realize the transmission of perception information.

In the first aspect, a communication method is provided, which can be executed by a terminal, or by a component of the terminal, such as a processor, chip, or chip system of the terminal, or by a logic module or software that can implement all or part of the terminal. The following is an illustration of the method being executed by a terminal. The communication method includes: acquiring multiple uplink control channel PUCCH resources, and based on the format of the first PUCCH resource, multiplexing the first PUCCH resource to transmit a perception request and a first information; wherein the multiple PUCCH resources include a PUCCH resource corresponding to the perception request and a PUCCH resource corresponding to the first information, the first information includes at least one of a hybrid automatic repeat request HARQ, a scheduling request SR, or a channel state CSI information, and the first PUCCH resource is any one of the multiple PUCCH resources.

In an embodiment of the present application, the terminal can obtain multiple PUCCH resources corresponding to the perception request and the first information, and determine a PUCCH resource from the above multiple PUCCH resources as the first PUCCH resource, so that the terminal can multiplex the first PUCCH resource to transmit the perception request and the first information based on the format of the first PUCCH resource, so that the perception request can be multiplexed and transmitted with the first information, which can improve the transmission performance of PUCCH, for example, reduce the occupancy rate of PUCCH resources, improve the utilization rate of PUCCH resources, etc., so as to create a better transmission environment for perception requests and better ensure the normal transmission of perception requests.

In combination with the above-mentioned first aspect, in a possible implementation method, the format of the first PUCCH resource is a first format, wherein the amount of transmission data corresponding to the first format is less than or equal to a first threshold, and the amount of time domain resources corresponding to the first format is less than a second threshold. In this case, the first PUCCH resource is multiplexed to transmit the perception request and the first information, including: transmitting a first sequence on the first PUCCH resource; wherein the cyclic shift of the first sequence is used to indicate the perception request and the first information, and the first information includes HARQ and/or SR.

That is, when the format of the first PUCCH resource is the first format, the terminal can obtain the perception request and the first information through the cyclic shift of the first sequence transmitted on the first PUCCH resource. Since the first sequence occupies fewer PUCCH resources than the perception request and the first information, in this implementation, the terminal can transmit the perception request and the first information through fewer PUCCH resources, further reducing the occupancy rate of the PUCCH resources, thereby further improving the utilization rate of the PUCCH resources.

In combination with the above-mentioned first aspect, in a possible implementation method, the number of cyclic shifts is determined according to the number of bits of the first information. For example, when the number of bits of the first information is 1 bit, the number of cyclic shifts is 4. For another example, when the number of bits of the first information is 2 bits, the number of cyclic shifts is 8. In this way, the terminal can control the number of cyclic shifts more accurately, thereby avoiding the adverse effects caused by insufficient or redundancy of cyclic shifts.

In combination with the above-mentioned first aspect, in a possible implementation method, the first information includes HARQ and SR; when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the cyclic shift of the first sequence is used to indicate a positive perception request and the first information, and the positive perception request is used to indicate the existence of a perception request; or, when the first PUCCH resource is a PUCCH resource corresponding to SR, the cyclic shift of the first sequence is used to indicate a negative perception request and the first information, and the negative perception request is used to indicate the absence of a perception request.

That is to say, when the format of the first PUCCH resource is the first format, in addition to indicating the perception request and the first information through the cyclic shift of the first sequence, the terminal can also jointly determine the perception request and the first information through the first PUCCH resource and the cyclic shift of the first sequence. This provides another implementation method for transmitting the perception request and the first information. When the number of cyclic shifts is insufficient, the first PUCCH resource can also be normally multiplexed through the above implementation method to complete the transmission of the perception request and the first information, thereby improving the reliability of transmitting the perception request and the first information.

In combination with the above-mentioned first aspect, in a possible implementation method, the format of the PUCCH resource is a second format, wherein the amount of transmission data corresponding to the second format is less than or equal to the first threshold, and the amount of time domain resources corresponding to the second format is greater than or equal to the second threshold; when the first PUCCH resource is a PUCCH resource for a perception request, the perception request is a positive perception request, and the positive perception request is used to indicate the presence of a perception request; or, when the first PUCCH resource is a PUCCH resource corresponding to HARQ or a PUCCH resource corresponding to SR, the perception request is a negative perception request, and the negative perception request is used to indicate the absence of a perception request.

That is to say, when the format of the first PUCCH resource is the second format, the terminal can transmit the perception request through the first PUCCH resource, so that the perception request does not need to occupy the first PUCCH resource, so that the terminal can transmit the perception request and the first information through fewer PUCCH resources, further reducing the occupancy rate of the PUCCH resources, and further improving the utilization rate of the PUCCH resources.

In combination with the above-mentioned first aspect, in a possible implementation method, the format of the first PUCCH resource is the third format, and the first PUCCH resource is multiplexed to transmit the perception request and the first information, including: multiplexing the first PUCCH resource to transmit the perception request and the first information, wherein the amount of transmission data corresponding to the third format is greater than the first threshold.

That is to say, when the format of the first PUCCH resource is the third format, since the amount of transmission data corresponding to the third format is large, even if the terminal transmits the perception request and the first information normally on the first PUCCH resource, it will not affect the stability of information transmission, thereby ensuring the stability of transmitting the perception request and the first information.

In combination with the above-mentioned first aspect, in a possible implementation method, the method provided by an embodiment of the present application also includes: multiplexing the first PUCCH resource to transmit a perception request, first information, and second information, the second information including the type of perception data and/or the service quality of the perception data.

As can be seen from the aforementioned introduction to the "third format", the amount of transmission data corresponding to the third format is greater than the first threshold, that is, the amount of transmission data corresponding to the third format is larger, so that the terminal can also reuse the first PUCCH resource to transmit more information, for example, perception requests, first information, and second information, which can further reduce the occupancy rate of PUCCH resources and further improve the utilization rate of PUCCH resources.

In combination with the above-mentioned first aspect, in a possible implementation method, the method provided by an embodiment of the present application also includes: when the number of bits of the third information is greater than the first number of bits, discarding part of the information in the third information, wherein the third information includes a perception request, first information, and second information, and the first number of bits is determined based on the first PUCCH resource and code rate.

That is to say, when the number of bits of the third information exceeds the first number of bits determined based on the configuration parameters, the terminal needs to discard part of the third information to ensure normal transmission of the third information and avoid the problem of transmission failure of the third information due to congestion as much as possible.

In combination with the above-mentioned first aspect, in a possible implementation method, the method provided in the embodiment of the present application also includes: sorting the information in the third information based on the priority of the information included in the third information, and determining part of the information from the sorted third information, so that part of the information with lower priority can be discarded from the third information to avoid the operation of discarding part of the information causing a greater impact on the communication network, thereby ensuring the normal operation of the communication network as much as possible.

In combination with the first aspect above, in a possible implementation method, the priority of any information in the first information is higher than the priority of the perception request; or, the priority of some information in the first information is higher than the priority of the perception request. The above provides two priority sorting rules for sorting the information in the third information, so that the terminal can adaptively sort the information in the third information based on actual conditions, so that the partial information determined subsequently can be more in line with the actual conditions.

In a second aspect, a communication device is provided for implementing the various methods described above.

DETAILED DESCRIPTION

To facilitate understanding of the technical solutions provided by the embodiments of the present application, a brief introduction to the related technologies of the present application is first given. The brief introduction is as follows:

1. Uplink control information (UCI)

Among them, UCI may refer to control information transmitted through the uplink, which can be used to assist the communication between the terminal and the network side device. During the uplink transmission process, the terminal can send UCI to the network device through the physical uplink control channel (physical uplink control channel, PUCCH). UCI may include at least one of hybrid automatic repeat request (HARQ), scheduling request (SR), and channel state information (CSI). Of course, the above is an exemplary description of UCI, and UCI may also include other information, and the embodiments of the present application do not impose any restrictions on this.

Among them, HARQ is used to feedback whether the terminal has successfully received the data packet from the network device, wherein HARQ may include HARQ-acknowledgement (ACK) or HARQ-negative acknowledgement (NACK), HARQ-ACK is used to indicate that the terminal has successfully received the data packet from the network device, and HARQ-NACK is used to indicate that the terminal has not successfully received the data packet from the network device.

SR is used to request uplink transmission resources. For SR, the network device can configure periodic transmission resources for SR, so that when there is an SR to be sent on the periodic transmission resources configured for SR, the SR can be called a positive SR (positive SR); when there is no SR to be sent on the periodic transmission resources configured for SR, the SR can be called a negative SR (negative SR). Exemplarily, as shown in Figure 1, when there is no SR to be sent on transmission resource 1 and transmission resource 3, the SR is a negative SR, and when there is an SR to be sent on transmission resource 2, the SR is a positive SR.

CSI is used to indicate the attribute information of the channel, wherein CSI may include CSI-part 1 and/or CSI-part 2. For different types of CSI, CSI-part1 and CSI-part2 include different contents. For example, for the first type of CSI, CSI-part1 includes at least one of the following: rank indicator (RI), CSI-resource indicator (RS), CQI of the first codeword, and CSI-part2 includes at least one of the following: precoding matrix indicator (PMI), layer indicator (LI), or CQI of the second codeword.

For another example, for the second type of CSI, CSI-part1 includes at least one of the following: RI, CQI, or an indication of the number of non-zero wideband amplitude coefficients corresponding to each layer, and CSI-part2 includes PMI and/or LI.

For another example, for the enhanced second type of CSI, CSI-part1 includes at least one of the following: RI, CQI, or an indication of the number of non-zero wideband amplitude coefficients corresponding to all layers, and CSI-part2 includes PMI.

2. Transmission resources

The transmission resources involved in the embodiments of the present application include time domain resources and frequency domain resources. The transmission resources can be replaced by the description of resources. If there is no special explanation, the resources in the embodiments of the present application refer to transmission resources.

Among them, the time domain resource may refer to any one of the following: a frame, a subframe, a time slot, a bundle group of multiple time slots, or an OFDM symbol. A frame includes multiple consecutive subframes, a subframe includes multiple consecutive time slots, and a time slot includes multiple consecutive orthogonal frequency division multiplexing (OFDM) symbols. OFDM symbols can also be replaced by symbols or time domain symbols. If not otherwise specified, the symbols in the embodiments of the present application refer to time domain symbols.

Frequency domain resources may refer to any of the following: RB, or RB group. RB may also be referred to as a physical resource block (PRB). An RB is generally composed of N resource elements (RE), and an RE may also be referred to as a subcarrier. N is generally 12, but N may also be other values, which are not specifically limited in the embodiments of the present application.

During uplink transmission, PUCCH resources can be allocated to the terminal so that the terminal sends PUCCH carrying UCI to the network device on the PUCCH resources. PUCCH resources can also replace the transmission resources described as PUCCH or PUCCH. Among them, the formats of PUCCH resources can be the following 5 types: PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3, and PUCCH format 4. As shown in Table 1 below, the format requirements of PUCCH resources generally include format type, number of occupied symbols, number of occupied RBs, amount of transmitted data, application scenarios, information carried on PUCCH, or whether terminal code division multiplexing is supported.

Table 1

Among them, as shown in Table 1 above, the format requirements corresponding to PUCCH format 0 may include: the format type is short format; the number of occupied symbols is 1 or 2; the number of occupied RBs is 1; the amount of transmitted data is less than or equal to 2 bits; the application scenario is an ultra-low latency scenario; the information carried on the PUCCH includes HARQ and/or SR; and terminal code division multiplexing is supported. In addition, when the format of the PUCCH resource is PUCCH format 0, the information carried on the PUCCH can be transmitted in the form of a low-peak-to-average power ratio (low-PAPR) sequence, so that the information carried on the PUCCH does not need to be encoded or scrambled, and there is no need to send a demodulation reference signal (DMRS) for the information carried on the PUCCH.

Exemplarily, as shown in FIG2 , taking the format requirements corresponding to PUCCH format 0 as follows: the number of occupied symbols is 1, and the number of occupied RBs is 1 as an example: the information carried on PUCCH can occupy symbol 13, and the information carried on PUCCH can occupy one RB (i.e., subcarrier 0 to subcarrier 11).

As shown in Table 1 above, the format requirements corresponding to PUCCH format 1 may include: the format type is long format; the number of occupied symbols is within [4, 14]; the number of occupied RBs is 1; the amount of transmitted data is less than or equal to 2 bits; the application scenario is a coverage improvement scenario; the information carried on the PUCCH includes HARQ and/or SR; and terminal code division multiplexing is supported. In addition, when the format of the PUCCH resource is PUCCH format 1, the terminal can also send the DMRS of the information carried on the PUCCH to the network device through the PUCCH. Among them, the frequency domain resources of the DMRS of the information carried on the PUCCH and the information carried on the PUCCH are the same, while the time domain resources of the DMRS of the information carried on the PUCCH and the information carried on the PUCCH are different. For example, the DMRS of the information carried on the PUCCH and the information carried on the PUCCH occupy different symbols in a time slot.

Exemplarily, as shown in FIG3, the format requirements corresponding to PUCCH format 1 are: the number of occupied symbols is 7, and the number of occupied RBs is 1. For example, the information carried on the PUCCH can occupy symbols 1, 3, 5, 7, 9, 11, and 13, and the information carried on the PUCCH can occupy one RB (i.e., subcarrier 0 to subcarrier 11). In addition, other symbols on the time slot can be used for the DMRS of the information carried on the PUCCH, that is, the DMRS of the information carried on the PUCCH can occupy symbols 0, 2, 4, 6, 7, 10, and 12, and the information carried on the PUCCH can occupy one RB (i.e., subcarrier 0 to subcarrier 11).

Optionally, when the format of the PUCCH resource is PUCCH format 1, when the information carried on the PUCCH includes HARQ and the number of bits of the above HARQ is 1, the terminal may use binary phase shift keying (BPSK) to modulate the HARQ; when the information carried on the PUCCH includes HARQ and the number of bits of the above HARQ is 2, the terminal may use quadrature phase shift keying (QPSK) to modulate the HARQ.

As shown in Table 1 above, the format requirements corresponding to PUCCH format 2 may include: the format type is short format; the number of occupied symbols is 1 or 2; the number of occupied RBs is within [1, 16]; the amount of transmitted data is greater than 2 bits; the application scenario is an ultra-low latency scenario; the information carried on the PUCCH includes at least one of HARQ, SR, or CSI; and terminal code division multiplexing is not supported. In addition, when the format of the PUCCH resource is PUCCH format 2, the terminal can also send the DMRS of the information carried on the PUCCH to the network device through the PUCCH. Among them, the time domain resources of the DMRS of the information carried on the PUCCH and the information carried on the PUCCH are the same, while the frequency domain resources of the DMRS of the information carried on the PUCCH and the information carried on the PUCCH are different. For example, the DMRS of the information carried on the PUCCH and the information carried on the PUCCH occupy different REs in one RB.

Exemplarily, as shown in FIG4 , taking the format requirements corresponding to PUCCH format 2 as follows: the number of occupied symbols is 1, and the number of occupied RBs is 1 as an example: the information carried on the PUCCH can occupy symbol 13, and the information carried on the PUCCH can occupy subcarrier 0, subcarrier 2, subcarrier 3, subcarrier 5, subcarrier 6, subcarrier 8, subcarrier 9, and subcarrier 11. In addition, the DMRS of the information carried on the PUCCH can occupy symbol 13, and the information carried on the PUCCH can occupy subcarrier 1, subcarrier 4, subcarrier 7, and subcarrier 10, that is, the terminal can deploy a DMRS carrying the information on the PUCCH every 3 REs.

As shown in Table 1 above, the format requirements corresponding to PUCCH format 3 may include: the format type is long format; the number of occupied symbols is within [4, 14]; the number of occupied RBs is any one of the following: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, and 16; the amount of data transmitted is greater than 2 bits; the application scenario is a coverage improvement scenario; the information carried on the PUCCH includes at least one of HARQ, SR, or CSI; and terminal code division multiplexing is not supported. In addition, when the format of the PUCCH resource is PUCCH format 3, the terminal can also send the DMRS of the information carried on the PUCCH to the network device through the PUCCH. Among them, the frequency domain resources of the information carried on the PUCCH and the DMRS of the information carried on the PUCCH are the same, while the time domain resources of the information carried on the PUCCH and the DMRS of the information carried on the PUCCH are different. For example, the DMRS of the information carried on the PUCCH and the DMRS of the information carried on the PUCCH occupy different symbols in a time slot.

Exemplarily, as shown in FIG5 , taking the format requirements corresponding to PUCCH format 3 as follows: the number of occupied symbols is 2, and the number of occupied RBs is 1 as an example: the information carried on the PUCCH can occupy symbols 3 and 10, and the information carried on the PUCCH can occupy one RB (i.e., subcarrier 0 to subcarrier 11). In addition, the DMRS of the information carried on the PUCCH can occupy symbols 0 to 2, symbols 4 to 9, and symbols 11 to 13, and the information carried on the PUCCH can occupy one RB (i.e., subcarrier 0 to subcarrier 11).

Optionally, when the format of the PUCCH resources is PUCCH format 3, more PUCCH resources are configured for information carried on the PUCCH, so that the load capacity of the PUCCH resources configured for information carried on the PUCCH is stronger.

As shown in Table 1 above, the format requirements corresponding to PUCCH format 4 may include: the format type is long format; the number of occupied symbols is within [4, 14]; the number of occupied RBs is 1; the amount of transmitted data is greater than 2 bits; the application scenario is a coverage improvement scenario and/or a user number improvement scenario; the information carried on the PUCCH includes at least one of HARQ, SR, or CSI; and terminal code division multiplexing is supported. In addition, when the format of the PUCCH resource is PUCCH format 4, the terminal can also send the DMRS of the information carried on the PUCCH to the network device through the PUCCH. Among them, the frequency domain resources of the information carried on the PUCCH and the DMRS of the information carried on the PUCCH are the same, while the time domain resources of the information carried on the PUCCH and the DMRS of the information carried on the PUCCH are different. For example, the DMRS of the information carried on the PUCCH and the DMRS of the information carried on the PUCCH occupy different symbols in a time slot.

It should be pointed out that PUCCH format 4 is similar to PUCCH format 3. For other descriptions of PUCCH format 4, please refer to the relevant descriptions of PUCCH format 3 and will not be repeated here.

3. Multiplexing of multiple information in UCI

In the case where UCI includes multiple information, each information can be multiplexed on the same PUCCH to save PUCCH resources and thus improve the utilization rate of PUCCH resources. As mentioned above about the "PUCCH resource format", the PUCCH resource format can include the following 5 types: PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3, and PUCCH format 4. However, for PUCCHs of different formats, the multiplexing method between multiple information is also different. The following is a detailed description of the multiplexing method between multiple information in the case of 5 PUCCH resource formats.

When the format of the PUCCH resource is PUCCH format 0, multiple information in the UCI (i.e., HARQ and SR) can be mapped to the cyclic shift (sequence cyclic shift), so that the cyclic shift can be used to characterize multiple information in the UCI. In the subsequent transmission process, the cyclic shift is transmitted based on the PUCCH, so that the multiple information in the UCI can be multiplexed on the same PUCCH.

An example, as shown in Table 2 below, takes the case where the number of HARQ bits is 1, the HARQ corresponding to the data packet is 0, indicating that the terminal has not successfully received the data packet, and the HARQ corresponding to the data packet is 1, indicating that the terminal has successfully received the data packet as an example: when the cyclic shift is 3, the cyclic shift can characterize the SR as a positive SR, and the HARQ corresponding to the data packet is 0, that is, the HARQ indicates that the terminal has not successfully received the data packet; when the cyclic shift is 9, the cyclic shift can characterize the SR as a positive SR, and the HARQ corresponding to the data packet is 1, and the HARQ indicates that the terminal has successfully received the data packet; when the cyclic shift is 0, the cyclic shift can characterize the SR as a negative SR, and the HARQ corresponding to the data packet is 0, and the HARQ indicates that the terminal has not successfully received the data packet; when the cyclic shift is 6, the cyclic shift can characterize the SR as a negative SR, and the HARQ corresponding to the data packet is 1, that is, the HARQ indicates that the terminal has successfully received the data packet.

Table 2

Another example, as shown in Table 3 below, takes the HARQ bit number as 2, and HARQ correspondingly indicates whether two data packets are successfully received as an example: when the cyclic shift is 1, it can be characterized that the SR is a positive SR, and the HARQ corresponding to the two data packets are both 0, that is, the HARQ indicates that the terminal has not successfully received the two data packets;

When the cyclic shift is 4, the cyclic shift can indicate that the SR is a positive SR, the HARQ corresponding to the first data packet is 0, and the HARQ corresponding to the first data packet is 1, that is, the terminal successfully receives the second data packet;

When the cyclic shift is 7, the cyclic shift can indicate that the SR is a positive SR, and the HARQs corresponding to the two data packets are both 1, that is, the HARQ indicates that the terminal has successfully received the two data packets;

When the cyclic shift is 10, the cyclic shift can indicate that the SR is a positive SR, the HARQ corresponding to the first data packet is 1, and the HARQ corresponding to the first data packet is 0, that is, the terminal successfully receives the first data packet;

When the cyclic shift is 0, the cyclic shift can indicate that the SR is a negative SR, and the HARQs corresponding to the two data packets are both 0, that is, the HARQ indicates that the terminal has not successfully received the two data packets;

When the cyclic shift is 3, the cyclic shift can indicate that the SR is a negative SR, the HARQ corresponding to the first data packet is 0, and the HARQ corresponding to the second data packet is 1, that is, the terminal successfully receives the second data packet;

When the cyclic shift is 6, the cyclic shift can indicate that the SR is a negative SR, and the HARQs corresponding to the two data packets are both 1, that is, the HARQ indicates that the terminal has successfully received the two data packets;

When the cyclic shift is 9, the cyclic shift can indicate that the SR is a negative SR, the HARQ corresponding to the first data packet is 1, and the HARQ corresponding to the first data packet is 0, that is, the terminal successfully receives the first data packet.

Table 3

When the format of the PUCCH resource is PUCCH format 1, the HARQ in the UCI can be transmitted normally, and the SR in the UCI can be determined by the PUCCH resources. In this way, the effect of multiplexing the HARQ and SR in the UCI on the same PUCCH can be achieved through implicit indication.

Exemplarily, as shown in Figure 6, when the PUCCH resource for transmitting HARQ is the PUCCH resource corresponding to SR (or called SR resource/SR transmission resource), the SR is a positive SR, and when the PUCCH resource for transmitting HARQ is the PUCCH resource corresponding to HARQ (or called HARQ resource/HARQ transmission resource), the SR is a negative SR.

When the format of the PUCCH resource is PUCCH format 2, PUCCH format 3 or PUCCH format 4, since the PUCCH resource in this format can transmit a large amount of data, the terminal can normally transmit multiple information in UCI (such as HARQ, SR, and CSI) on the PUCCH resource without establishing a correspondence between the multiple information in UCI and the cyclic shift or implicitly indicating it to achieve the effect of multiplexing multiple information in UCI on the same PUCCH.

It should be pointed out that when the format of the PUCCH resource is PUCCH format 2, PUCCH format 3 or PUCCH format 4, HARQ, SR, and CSI-part1 can be encoded together, while CSI-part2 can be encoded independently. After the terminal encodes HARQ, SR, CSI-part1, and CSI-part2, the terminal can also generate a bit stream in a preset order. For example, as shown in Figure 7, the preset order can be HARQ-SR-CSI part 1-CSI part 2. Of course, the above is an exemplary description of the preset order, and the preset order can also be other orders. The embodiments of the present application do not impose any restrictions on this.

In addition, when the sum of the number of HARQ bits, the number of SR bits, the number of CSI part 1 bits, and the number of CSI part 2 bits is less than or equal to the maximum number of bits configured for UCI, the terminal can reuse PUCCH to send HARQ, SR, CSI part 1, and CSI part 2 to the network device. When the sum of the number of HARQ bits, the number of SR bits, the number of CSI part 1 bits, and the number of CSI part 2 bits is greater than the maximum number of bits corresponding to UCI, the terminal can discard part of the information in UCI in the above-mentioned preset order until the number of UCI bits is less than or equal to the maximum number of bits configured for UCI, and reuse PUCCH to send the discarded UCI to the network device.

Optionally, the maximum number of bits configured for UCI may be determined by parameters such as the PUCCH resource amount and the code rate. For example, the maximum number of bits configured for UCI satisfies the following formula 1:

in, Maximum number of bits configured for UCI. Indicates the number of RBs configured for the UCI. Used to indicate the number of REs included in an RB. It is used to indicate the number of symbols remaining in the time domain resources configured for UCI, excluding the time domain resources of DMRS. _Qm is used to indicate the modulation order configured for UCI. r is the maximum code rate in the PUCCH configuration.

In addition, optionally, the priority of the CSI may be calculated by the following formula 2 or satisfy the formula 2:
Pri _iCSI (y,k,c,s)＝2·N _cells ·M _s ·y+N _cells ·M _s ·k+M _s ·c+s Formula 2

Among them, y is used to indicate the transmission mode (for example, periodic transmission/semi-static transmission/non-periodic transmission). K is used to indicate whether the CSI includes information related to signal strength (for example, reference signal receiving power (RSRP) or signal to interference plus noise ratio (SINR)). C is used to indicate the index of the serving cell. N _cells is the value of the high-level parameter maximum number of serving cells (max Nrof Serving Cells), which is used to indicate the maximum number of serving cells. s represents the report configuration identity (report configuration ID), that is, the index of the CSI reporting configuration. _Ms is the value of the high-level parameter maximum number of CSI report configurations (max nrof CSI-report configurations), which indicates the maximum number of CSI reporting configurations.

At present, reducing latency and improving throughput, reliability, number of connections, and spectrum utilization have always been the core challenges of wireless communication networks. In order to meet the above challenges, the ^fifth generation mobile communication technology (5G) has proposed enhanced mobile broadband (eMBB), ultra-reliable low latency communications (URLLC), massive machine type communications (mMTC) and other applications. With the rapid development of wireless communication networks, the future ^sixth generation mobile communication technology (6G) will inevitably evolve towards higher throughput, lower latency, higher reliability, larger number of connections, and higher spectrum utilization.

However, as a key technology of 6G, perception technology can be combined with existing communication technology to achieve the purpose of assisting communication. In one possible implementation, perception technology is effectively combined with artificial intelligence (AI)/machine learning (ML), so that perception data can be used as input to AI or ML models, so that the output of AI or ML models can better assist communication. In addition, AI technology can also be used to determine the method of obtaining perception data, such as determining the optimal configuration for measuring and reporting perception signals. In another possible implementation, perception data can also be effectively combined with wireless transmission technology, so that perception data can also be transmitted by wireless transmission to achieve the purpose of assisting communication.

In view of the above, it can be seen that for communication systems, perception technology plays a great auxiliary role. Therefore, in communication systems that support perception technology, how to transmit perception information, such as perception requests, becomes a problem that needs to be solved urgently.

Based on this, an embodiment of the present application provides a communication method, in which a terminal can obtain multiple PUCCH resources corresponding to a perception request and a first information, and determine a PUCCH resource from the above multiple PUCCH resources as a first PUCCH resource, so that the terminal can multiplex the first PUCCH resource to transmit the perception request and the first information based on the format of the first PUCCH resource, so that the perception request can be multiplexed and transmitted with the first information, which can improve the transmission performance of PUCCH, for example, reduce the occupancy rate of PUCCH resources, improve the utilization rate of PUCCH resources, etc., so as to create a better transmission environment for perception requests and better ensure the normal transmission of perception requests.

In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein the other information has an association with the information to be indicated. It is also possible to indicate a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved by means of the arrangement order of each piece of information agreed in advance (such as specified by the protocol), thereby reducing the indication overhead to a certain extent.

For example, A/B can represent A or B; "and/or" in the embodiments of the present application is a kind of association relationship that describes the associated objects, indicating that there can be three relationships.

FIG10 is an example of a communication method provided in an embodiment of the present application. The method is described with a terminal as the execution subject. Of course, the subject that executes the terminal action in the method can also be a device/module in the terminal, such as a chip, processor, processing unit, etc. in the terminal, which is not specifically limited in the embodiment of the present application. For example, as shown in FIG10, the communication method includes the following steps:

S1001. The terminal obtains multiple PUCCH resources.

The multiple PUCCH resources include PUCCH resources corresponding to the sensing request and PUCCH resources corresponding to the first information. The first information includes at least one of HARQ, SR, or CSI.

Assume that the first information includes HARQ or SR or CSI: the above-mentioned multiple PUCCH resources include: PUCCH resources corresponding to the perception request, and any one of the PUCCH resources corresponding to HARQ, the PUCCH resources corresponding to SR, and the PUCCH resources corresponding to CSI.

Assuming that HARQ and SR are multiplexed in the first information (it can also be understood that the first information includes HARQ and SR): the above-mentioned multiple PUCCH resources include: PUCCH resources corresponding to the perception request, PUCCH resources corresponding to HARQ, and PUCCH resources corresponding to SR.

Assume that the first information includes HARQ, SR, and CSI: the above-mentioned multiple PUCCH resources include: PUCCH resources corresponding to the perception request, PUCCH resources corresponding to HARQ, PUCCH resources corresponding to SR, and PUCCH resources corresponding to CSI.

Of course, the above is an exemplary description of the first information, and the first information may also include other information, and the embodiments of the present application do not impose any limitations on this.

Optionally, the above-mentioned sensing request may include a positive sensing request or a negative sensing request. Among them, the positive sensing request is used to indicate that there is a sensing request, that is, there is a sensing request that needs to be sent on the PUCCH resource corresponding to the sensing request, and the negative sensing request is used to indicate that there is no sensing request, that is, there is no sensing request that needs to be sent on the PUCCH resource corresponding to the sensing request. In the present application, the sensing request can be used to request sensing data.

S1002. The terminal multiplexes the first PUCCH resource to transmit the perception request and the first information based on the format of the first PUCCH resource.

Specifically, the above S1002 may be: the terminal multiplexes the first PUCCH resource based on the format of the first PUCCH resource to transmit the perception request and the first information to the network device.

The first PUCCH resource is any one of the multiple PUCCH resources.

In an embodiment of the present application, the terminal can obtain multiple PUCCH resources corresponding to the perception request and the first information, and determine a PUCCH resource from the above multiple PUCCH resources as the first PUCCH resource, so that the terminal can multiplex the first PUCCH resource to transmit the perception request and the first information based on the format of the first PUCCH resource, so that the perception request can be multiplexed and transmitted with the first information, which can improve the transmission performance of PUCCH, for example, reduce the occupancy rate of PUCCH resources, improve the utilization rate of PUCCH resources, etc., so as to create a better transmission environment for perception requests and better ensure the normal transmission of perception requests.

Optionally, the format of the PUCCH resource described in the present application may include at least one of the following: a first format, a second format, or a third format. The amount of transmission data corresponding to the first format is less than or equal to a first threshold, and the amount of time domain resources corresponding to the first format is less than a second threshold. The amount of transmission data corresponding to the second format is less than or equal to the first threshold, and the amount of time domain resources corresponding to the second format is greater than or equal to the second threshold. The amount of transmission data corresponding to the third format is greater than the first threshold.

As mentioned above about the format of PUCCH resources, the formats of PUCCH resources may include PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3, and PUCCH format 4. Assuming that the first threshold is 2 and the second threshold is 2: the first format may be PUCCH format 0, the second format may be PUCCH format 1, and the third format may include at least one of the following: PUCCH format 2, PUCCH format 3, and PUCCH format 4. Of course, the above is an exemplary description of the first threshold and the second threshold, and the first threshold and the second threshold may also be other values, and the embodiments of the present application do not impose any restrictions on this.

Furthermore, if the format of the first PUCCH resource is different, the implementation method of the terminal multiplexing the first PUCCH resource to transmit the perception request and the first information is also different. In view of this, the embodiment of the present application can be divided into the following three cases based on the format of the first PUCCH resource: Case 1, the format of the first PUCCH resource is the first format; Case 2, the format of the first PUCCH resource is the second format; Case 3, the format of the first PUCCH resource is the third format. The following describes in detail the implementation process of the terminal multiplexing the first PUCCH resource to transmit the perception request and the first information in different cases.

Case 1: The format of the first PUCCH resource is the first format.

In case 1, in a possible implementation, the implementation process of the terminal multiplexing the first PUCCH resource to transmit the perception request and the first information may include: the terminal may transmit a first sequence on the first PUCCH resource. The cyclic shift of the first sequence is used to indicate the perception request and the first information. The first information includes HARQ and/or SR.

Optionally, when the format of the first PUCCH resource is the first format, the terminal can obtain the perception request and the first information through the cyclic shift of the first sequence transmitted on the first PUCCH resource. Since the first sequence occupies fewer PUCCH resources than the perception request and the first information, in this implementation, the terminal can transmit the perception request and the first information through fewer PUCCH resources, further reducing the occupancy rate of the PUCCH resources, thereby further improving the utilization rate of the PUCCH resources.

Optionally, the number of cyclic shifts of the above-mentioned first sequence is determined according to the number of bits of the first information, so that the terminal can more accurately control the number of cyclic shifts, thereby avoiding the adverse effects caused by insufficient cyclic shifts or redundancy. In one possible implementation, when the number of bits of the first information is 1 bit, the number of cyclic shifts of the first sequence is 4, and when the number of bits of the first information is 2 bits, the number of cyclic shifts of the first sequence is 8. In another possible implementation, when the number of bits of the first information is 1 bit, the number of cyclic shifts of the first sequence is 3, and when the number of bits of the first information is 2 bits, the number of cyclic shifts of the first sequence is 8. Of course, the above is an exemplary description of the relationship between the number of bits of the first information and the number of cyclic shifts of the first sequence. There may be other relationships between the number of bits of the first information and the number of cyclic shifts of the first sequence, and the embodiments of the present application do not impose any restrictions on this.

In one example, it is assumed that the first information includes HARQ, and the number of bits of HARQ is 1, HARQ is represented by a binary bit value, HARQ is 0 to indicate that the data packet is not successfully received, and HARQ is 1 to indicate that the data packet is successfully received. As shown in Table 4 below, when the cyclic shift of the first sequence is 3, the cyclic shift of the first sequence can be used to indicate that the sensing request is a positive sensing request (corresponding to the positive in Table 4), and the HARQ corresponding to the data packet is 0, that is, the HARQ indicates that the terminal has not successfully received the data packet. When the cyclic shift of the first sequence is 9, the cyclic shift of the first sequence can be used to indicate that the sensing request is a positive sensing request (corresponding to the positive in Table 4), and the HARQ corresponding to the data packet is 1, that is, the HARQ indicates that the terminal has successfully received the data packet. When the cyclic shift of the first sequence is 0, the cyclic shift of the first sequence can be used to indicate that the sensing request is a negative sensing request (corresponding to the negative in Table 4), and the HARQ corresponding to the data packet is 0, that is, the HARQ indicates that the terminal has not successfully received the data packet. When the cyclic shift of the first sequence is 6, the cyclic shift of the first sequence can be used to characterize: the perception request is a negative perception request (corresponding to negative in Table 4), and the HARQ corresponding to the data packet is 1, that is, the HARQ indicates that the terminal successfully receives the data packet.

Table 4

As can be seen from Table 4 above, since the first information includes 1 bit of HARQ, the number of cyclic shifts of the first sequence is 4.

Of course, the above is an exemplary description of the cyclic shift of the first sequence. In this case, the terminal can also configure the cyclic shift of the first sequence to other values to characterize the perception request and 1-bit HARQ. For example, when the cyclic shift of the first sequence is 2, the cyclic shift of the first sequence can be used to characterize: the perception request is a positive perception request (corresponding to positive in Table 5), and the HARQ indicates that the terminal has not successfully received the data packet. The embodiments of the present application do not impose any restrictions on this.

Another example, as shown in the following Table 5, assume that the first information includes HARQ, and the number of bits of HARQ is 2: when the cyclic shift of the first sequence is 1, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a positive sensing request (corresponding to positive in Table 5), and the HARQs corresponding to the two data packets are both 0, that is, the HARQ indication terminal has not successfully received the two data packets;

When the cyclic shift of the first sequence is 4, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a positive sensing request (corresponding to positive in Table 5), and the HARQ corresponding to the first data packet is 0, while the HARQ corresponding to the first data packet is 1, that is, the terminal successfully receives the second data packet;

When the cyclic shift of the first sequence is 7, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a positive sensing request (corresponding to positive in Table 5), and the HARQs corresponding to the two data packets are both 1, that is, the HARQ indicates that the terminal successfully receives the two data packets;

When the cyclic shift of the first sequence is 10, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a positive sensing request (corresponding to positive in Table 5), and the HARQ corresponding to the first data packet is 1, while the HARQ corresponding to the first data packet is 0, that is, the terminal successfully receives the first data packet;

When the cyclic shift of the first sequence is 0, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a negative sensing request (corresponding to negative in Table 5), and the HARQs corresponding to the two data packets are both 0, that is, the HARQ indicates that the terminal has not successfully received the two data packets;

When the cyclic shift of the first sequence is 3, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a negative sensing request (corresponding to negative in Table 5), and the HARQ corresponding to the first data packet is 0, while the HARQ corresponding to the first data packet is 1, that is, the terminal successfully receives the second data packet;

When the cyclic shift of the first sequence is 6, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a negative sensing request (corresponding to negative in Table 5), and the HARQs corresponding to the two data packets are both 1, that is, the HARQ indicates that the terminal successfully receives the two data packets;

When the cyclic shift of the first sequence is 9, the cyclic shift of the first sequence can be characterized as follows: the perception request is a negative perception request (corresponding to negative in Table 5), and the HARQ corresponding to the first data packet is 1, while the HARQ corresponding to the first data packet is 0, that is, the terminal successfully receives the first data packet.

Table 5

As can be seen from Table 5 above, since the first information includes 2 bits of HARQ, the number of cyclic shifts of the first sequence is 8.

Of course, the above is an exemplary description of the cyclic shift of the first sequence. In this case, the terminal can also configure the cyclic shift of the first sequence to other values to characterize the perception request and the 2-bit HARQ. For example, when the cyclic shift of the first sequence is 2, the cyclic shift of the first sequence can be characterized as: the perception request is a positive perception request (corresponding to the positive in Table 6), and the HARQs corresponding to the two data packets are both 0, that is, the HARQ indicates that the terminal has not successfully received the two data packets. The embodiments of the present application do not impose any restrictions on this.

In another example, as shown in Table 6 below, it is assumed that the first information includes SR: when the cyclic shift of the first sequence is 0, the cyclic shift of the first sequence can be used to characterize that the sensing request is a positive sensing request (corresponding to the positive in Table 6), and the SR is a positive SR (corresponding to the positive in Table 6). When the cyclic shift of the first sequence is 4, the sensing request is a negative sensing request (corresponding to the negative in Table 5), and the SR is a positive SR (corresponding to the positive in Table 6). When the cyclic shift of the first sequence is 8, the sensing request is a positive sensing request (corresponding to the positive in Table 6), and the SR is a negative SR (corresponding to the negative in Table 5).

Table 6

As can be seen from Table 6 above, since the first information includes 1-bit SR, the number of cyclic shifts of the first sequence is 3.

Optionally, when the SR is a negative SR and the sensing request is a negative sensing request, it indicates that the first PUCCH resource carries neither the SR nor the sensing request, so that the terminal may not transmit the sensing request and the SR.

Of course, the above is an exemplary description of the cyclic shift of the first sequence. In this case, the terminal can also configure the cyclic shift of the first sequence to other values to characterize the perception request and SR. For example, when the cyclic shift of the first sequence is 2, the cyclic shift of the first sequence can be used to characterize: the perception request is a positive perception request, and the SR is a positive SR. The embodiments of the present application do not impose any restrictions on this.

Another example, as shown in Table 7 below, assume that HARQ and SR are multiplexed in the first information, and the number of bits of HARQ is 1: when the cyclic shift of the first sequence is 1, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a positive sensing request (corresponding to the positive in Table 7), the SR is a positive SR (corresponding to the positive in Table 7), and the HARQ corresponding to the data packet is 0, that is, the HARQ indicates that the terminal has not successfully received the data packet;

When the cyclic shift of the first sequence is 4, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a negative sensing request (corresponding to negative in Table 7), the SR is a positive SR (corresponding to positive in Table 7), and the HARQ corresponding to the data packet is 0, that is, the HARQ indicates that the terminal has not successfully received the data packet;

When the cyclic shift of the first sequence is 7, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a positive sensing request (corresponding to the positive in Table 7), the SR is a negative SR (corresponding to the negative in Table 7), and the HARQ corresponding to the data packet is 0, that is, the HARQ indicates that the terminal has not successfully received the data packet;

When the cyclic shift of the first sequence is 10, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a negative sensing request (corresponding to negative in Table 7), the SR is a negative SR (corresponding to negative in Table 7), and the HARQ corresponding to the data packet is 0, that is, the HARQ indicates that the terminal has not successfully received the data packet;

When the cyclic shift of the first sequence is 0, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a positive sensing request (corresponding to positive in Table 7), the SR is a positive SR (corresponding to positive in Table 7), and the HARQ corresponding to the data packet is 1, that is, the HARQ indicates that the terminal successfully receives the data packet;

When the cyclic shift of the first sequence is 3, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a negative sensing request (corresponding to negative in Table 7), the SR is a positive SR (corresponding to positive in Table 7), and the HARQ corresponding to the data packet is 1, that is, the HARQ indicates that the terminal successfully receives the data packet;

When the cyclic shift of the first sequence is 6, the cyclic shift of the first sequence can be characterized as follows: the sensing request is a positive sensing request (corresponding to the positive in Table 7), the SR is a negative SR (corresponding to the negative in Table 7), and the HARQ corresponding to the data packet is 1, that is, the HARQ indicates that the terminal successfully receives the data packet;

When the cyclic shift of the first sequence is 9, the cyclic shift of the first sequence can be characterized as follows: the perception request is a negative perception request (corresponding to negative in Table 7), the SR is a negative SR (corresponding to negative in Table 7), and the HARQ corresponding to the data packet is 1, that is, the HARQ indicates that the terminal successfully receives the data packet.

Table 7

As can be seen from Table 7 above, since the first information includes 1-bit HARQ and 1-bit SR, the number of cyclic shifts of the first sequence is 8.

The above is an exemplary description of the cyclic shift of the first sequence. In this case, the terminal may also configure the cyclic shift of the first sequence to other values to characterize the sensing request, SR, and HARQ. For example, when the cyclic shift of the first sequence is 2, the cyclic shift of the first sequence may characterize: the sensing request is a positive sensing request, the SR is a positive SR, and the HARQ indicates that the terminal has not successfully received the data packet. The embodiments of the present application do not impose any restrictions on this.

In addition, when HARQ and SR are multiplexed in the first information and the number of bits of HARQ is 2 bits, if the terminal wants to use the cyclic shift of the first sequence to characterize the perception request, HARQ, and SR, 16 different values are required. In general, the cyclic shift of the first sequence includes 12 values (i.e., 0 to 11), which results in that the cyclic shift of the first sequence cannot fully characterize the perception request, HARQ, and SR. In view of this, the terminal can combine the first PUCCH resource and the cyclic shift of the first sequence to indicate the perception request and the first information through the first PUCCH resource and the cyclic shift of the first sequence. For example, when the first PUCCH resource is the PUCCH resource corresponding to HARQ, the cyclic shift of the first sequence is used to indicate the positive perception request and the first information; or, when the first PUCCH resource is the PUCCH resource corresponding to SR, the cyclic shift of the first sequence is used to indicate the negative perception request and the first information. Of course, the above is an exemplary description of the relationship between the first PUCCH resource and the cyclic shift of the first sequence. There may be other relationships between the first PUCCH resource and the cyclic shift of the first sequence. For example, when the first PUCCH resource is the PUCCH resource corresponding to SR, the cyclic shift of the first sequence is used to indicate a positive perception request and the first information; or, when the first PUCCH resource is the PUCCH resource corresponding to HARQ, the cyclic shift of the first sequence is used to indicate a negative perception request and the first information. The embodiments of the present application do not impose any restrictions on this.

Optionally, when the format of the first PUCCH resource is the first format, in addition to indicating the perception request and the first information through the cyclic shift of the first sequence, the terminal can also jointly determine the perception request and the first information through the first PUCCH resource and the cyclic shift of the first sequence. This provides another implementation method for transmitting the perception request and the first information. In the case where the number of cyclic shifts is insufficient, the first PUCCH resource can also be normally multiplexed through the above implementation method to complete the transmission of the perception request and the first information, thereby improving the reliability of transmitting the perception request and the first information.

For example, as shown in (a) of FIG. 11 , when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the cyclic shift of the first sequence is used to indicate a positive sensing request and the first information, and when the first PUCCH resource is a PUCCH resource corresponding to SR, the cyclic shift of the first sequence is used to indicate a negative sensing request and the first information;

For another example, as shown in (b) of FIG. 11 , when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the cyclic shift of the first sequence is used to indicate a negative sensing request and the first information, and when the first PUCCH resource is a PUCCH resource corresponding to SR, the cyclic shift of the first sequence is used to indicate a positive sensing request and the first information;

For another example, as shown in (c) of FIG. 11 , when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the cyclic shift of the first sequence is used to indicate a positive sensing request and the first information, and when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the cyclic shift of the first sequence is used to indicate a negative sensing request and the first information;

For another example, as shown in (d) of FIG. 11 , when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the cyclic shift of the first sequence is used to indicate a negative sensing request and the first information, and when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the cyclic shift of the first sequence is used to indicate a positive sensing request and the first information;

For another example, as shown in (e) of FIG. 11 , when the first PUCCH resource is a PUCCH resource corresponding to an SR, the cyclic shift of the first sequence is used to indicate a positive sensing request and the first information, and when the first PUCCH resource is a PUCCH resource corresponding to a sensing request, the cyclic shift of the first sequence is used to indicate a negative sensing request and the first information;

For another example, as shown in (f) in Figure 11, when the first PUCCH resource is a PUCCH resource corresponding to an SR, the cyclic shift of the first sequence is used to indicate a negative perception request and the first information, and when the first PUCCH resource is a PUCCH resource corresponding to a perception request, the cyclic shift of the first sequence is used to indicate a positive perception request and the first information.

Optionally, when HARQ and SR are multiplexed in the first information and the number of HARQ bits is 2 bits, the correspondence between the first information and the cyclic shift of the first sequence can be understood by referring to the description of the corresponding position above (for example, the description related to Table 3), and will not be repeated here.

In another possible implementation, the implementation process of the terminal multiplexing the first PUCCH resource to transmit the perception request and the first information may include: the terminal directly multiplexing the first PUCCH resource to transmit the perception request and the first information. The first information includes SR or 1-bit HARQ.

Optionally, the terminal may also send a perception request separately. In this case, the perception request may correspond to the cyclic shift separately. For example, as shown in Table 8 below, when the cyclic shift is 0, the perception request is a positive perception request.

Table 8

The above is an exemplary description of the relationship between the perception request and the cyclic shift. In this case, the terminal can also configure the cyclic shift to other values to characterize the perception request. For example, when the cyclic shift of the first sequence is 2, the perception request is a positive perception request. The embodiments of the present application do not impose any restrictions on this.

Case 2: The format of the first PUCCH resource is the second format.

In case 2, in a possible implementation, the implementation process of the terminal multiplexing the first PUCCH resource to transmit the perception request and the first information may include: the terminal transmits the perception request and a part of the first information on the first PUCCH resource, and determines the perception request and another part of the first information through the first PUCCH resource. The first information includes HARQ and/or SR.

Optionally, when the format of the first PUCCH resource is the second format, the terminal may transmit part of the information, for example, a perception request, through the first PUCCH resource. In this way, the perception request does not need to occupy the first PUCCH resource, so that the terminal can transmit the perception request and the first information through fewer PUCCH resources, further reducing the occupancy rate of the PUCCH resources, thereby further improving the utilization rate of the PUCCH resources.

In one example, as shown in FIG12 , it is assumed that the first information includes HARQ, and the number of bits of the HARQ is 1 bit or 2 bits: as shown in (a) of FIG12 , when the first PUCCH resource is a PUCCH resource corresponding to the HARQ, the sensing request is a positive sensing request, and when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the sensing request is a negative sensing request;

Alternatively, as shown in (b) of Figure 12, when the first PUCCH resource is the PUCCH resource corresponding to the perception request, the perception request is a positive perception request, and when the first PUCCH resource is the PUCCH resource corresponding to HARQ, the perception request is a negative perception request.

The above is an exemplary description of the relationship between the perception request and the first PUCCH resource when the first information includes HARQ and the number of bits of HARQ is 1 bit or 2 bits. There may be other relationships between the perception request and the first PUCCH resource, and the embodiments of the present application do not impose any restrictions on this.

In another example, as shown in FIG13 , it is assumed that the first information includes an SR, and the information transmitted by the terminal through the first PUCCH resource is an SR:

As shown in (a) of FIG. 13 , when the first PUCCH resource is a PUCCH resource corresponding to the SR, the sensing request is a positive sensing request, and when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the sensing request is a negative sensing request;

As shown in (b) of Figure 13, when the first PUCCH resource is the PUCCH resource corresponding to the perception request, the perception request is a positive perception request, and when the first PUCCH resource is the PUCCH resource corresponding to the SR, the perception request is a negative perception request.

Of course, the above is an exemplary description of the relationship between the perception request and the first PUCCH resource when the first information includes SR and the information transmitted by the terminal through the first PUCCH resource is SR. There may be other relationships between the perception request and the first PUCCH resource, and the embodiments of the present application do not impose any restrictions on this.

In another example, as shown in FIG14 , it is assumed that the first information includes an SR, and the information transmitted by the terminal through the first PUCCH resource is a perception request:

As shown in (a) of FIG. 14 , when the first PUCCH resource is a PUCCH resource corresponding to the SR, the SR is a positive SR, and when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the SR is a negative SR;

As shown in (b) of Figure 14, when the first PUCCH resource is the PUCCH resource corresponding to the perception request, the SR is a positive SR, and when the first PUCCH resource is the PUCCH resource corresponding to the SR, the SR is a negative SR.

Of course, the above is an exemplary description of the relationship between SR and the first PUCCH resource when the first information includes SR and the information transmitted by the terminal through the first PUCCH resource is a perception request. There may be other relationships between SR and the first PUCCH resource, and the embodiments of the present application do not impose any restrictions on this.

In another example, as shown in FIG15 , it is assumed that the first information includes SR and HARQ, the number of bits of HARQ is 1 bit, and the information transmitted by the terminal through the first PUCCH resource is SR and HARQ, wherein SR and HARQ occupy 1 bit respectively:

As shown in (a) of FIG. 15 , when the first PUCCH resource is a PUCCH resource corresponding to the SR, the sensing request is a positive sensing request, and when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the sensing request is a negative sensing request;

As shown in (b) of FIG. 15 , when the first PUCCH resource is a PUCCH resource corresponding to a sensing request, the sensing request is a positive sensing request, and when the first PUCCH resource is a PUCCH resource corresponding to an SR, the sensing request is a negative sensing request;

As shown in (c) of FIG. 15 , when the first PUCCH resource is a PUCCH resource corresponding to SR, the sensing request is a positive sensing request, and when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the sensing request is a negative sensing request;

As shown in (d) of FIG. 15 , when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the sensing request is a positive sensing request, and when the first PUCCH resource is a PUCCH resource corresponding to SR, the sensing request is a negative sensing request;

As shown in (e) of FIG. 15 , when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the sensing request is a positive sensing request, and when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the sensing request is a negative sensing request;

As shown in (f) in Figure 15, when the first PUCCH resource is the PUCCH resource corresponding to HARQ, the sensing request is a positive sensing request, and when the first PUCCH resource is the PUCCH resource corresponding to the sensing request, the sensing request is a negative sensing request.

The above is an exemplary description of the relationship between the perception request and the first PUCCH resource when the first information includes SR and HARQ, the number of bits of HARQ is 1 bit, and the information transmitted by the terminal through the first PUCCH resource is SR and HARQ. There may be other relationships between the perception request and the first PUCCH resource, and the embodiments of the present application do not impose any restrictions on this.

In another example, as shown in FIG16, it is assumed that the first information includes SR and HARQ, the number of bits of HARQ is 1 bit, and the information transmitted by the terminal through the first PUCCH resource is the perception request and HARQ, wherein the perception request and HARQ occupy 1 bit respectively:

As shown in (a) of FIG. 16 , when the first PUCCH resource is a PUCCH resource corresponding to the SR, the SR is a positive SR, and when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the SR is a negative SR;

As shown in (b) of FIG. 16 , when the first PUCCH resource is a PUCCH resource corresponding to a sensing request, the SR is a positive SR, and when the first PUCCH resource is a PUCCH resource corresponding to an SR, the SR is a negative SR;

As shown in (c) of FIG. 16 , when the first PUCCH resource is a PUCCH resource corresponding to SR, SR is a positive SR, and when the first PUCCH resource is a PUCCH resource corresponding to HARQ, SR is a negative SR;

As shown in (d) of FIG. 16 , when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the SR is a positive SR, and when the first PUCCH resource is a PUCCH resource corresponding to SR, the SR is a negative SR;

As shown in (e) of FIG. 16 , when the first PUCCH resource is a PUCCH resource corresponding to a sensing request, the SR is a positive SR, and when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the SR is a negative SR;

As shown in (f) in Figure 16, when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the SR is a positive SR, and when the first PUCCH resource is a PUCCH resource corresponding to a perception request, the SR is a negative SR.

The above is an exemplary description of the relationship between SR and the first PUCCH resource when the first information includes SR and HARQ, the number of bits of HARQ is 1 bit, and the information transmitted by the terminal through the first PUCCH resource is a perception request and HARQ. There may be other relationships between SR and the first PUCCH resource, and the embodiments of the present application do not impose any restrictions on this.

In another example, as shown in FIG17 , it is assumed that the first information includes SR and HARQ, the number of bits of HARQ is 2 bits, and the information transmitted by the terminal through the first PUCCH resource is HARQ:

As shown in (a) of FIG. 17 , when the first PUCCH resource is a PUCCH resource corresponding to SR, the sensing request is a positive sensing request, and SR is a positive SR; when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the sensing request is a negative sensing request, and SR is a positive SR; when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the sensing request is a positive sensing request, and SR is a negative SR;

As shown in (b) of FIG. 17 , when the first PUCCH resource is a PUCCH resource corresponding to SR, the sensing request is a positive sensing request, and SR is a positive SR; when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the sensing request is a negative sensing request, and SR is a positive SR; when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the sensing request is a positive sensing request, and SR is a negative SR;

As shown in (c) of FIG. 17 , when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the sensing request is a positive sensing request, and the SR is a positive SR; when the first PUCCH resource is a PUCCH resource corresponding to SR, the sensing request is a negative sensing request, and the SR is a positive SR; when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the sensing request is a positive sensing request, and the SR is a negative SR;

As shown in (d) of FIG. 17 , when the first PUCCH resource is a PUCCH resource corresponding to HARQ, the sensing request is a positive sensing request and the SR is a positive SR; when the first PUCCH resource is a PUCCH resource corresponding to the sensing request, the sensing request is a negative sensing request and the SR is a positive SR; when the first PUCCH resource is a PUCCH resource corresponding to the SR, the sensing request is a positive sensing request and the SR is a negative SR;

As shown in (e) of FIG. 17 , when the first PUCCH resource is a PUCCH resource corresponding to a sensing request, the sensing request is a positive sensing request, and the SR is a positive SR; when the first PUCCH resource is a PUCCH resource corresponding to an SR, the sensing request is a negative sensing request, and the SR is a positive SR; when the first PUCCH resource is a PUCCH resource corresponding to an HARQ, the sensing request is a positive sensing request, and the SR is a negative SR;

As shown in (f) in Figure 17, when the first PUCCH resource is the PUCCH resource corresponding to the perception request, the perception request is a positive perception request and the SR is a positive SR; when the first PUCCH resource is the PUCCH resource corresponding to HARQ, the perception request is a negative perception request and the SR is a positive SR; when the first PUCCH resource is the PUCCH resource corresponding to SR, the perception request is a positive perception request and the SR is a negative SR.

Of course, the above is an exemplary description of the relationship between the perception request and the first PUCCH resource when the first information includes SR and HARQ, the number of HARQ bits is 2 bits, and the information transmitted by the terminal through the first PUCCH resource is HARQ. There may be other relationships between the perception request and the first PUCCH resource, and the embodiments of the present application do not impose any restrictions on this.

In another possible implementation, the implementation process of the terminal multiplexing the first PUCCH resource to transmit the perception request and the first information may include: the terminal directly multiplexing the first PUCCH resource to transmit the perception request and the first information. The first information includes SR or 1-bit HARQ.

As shown in (a) of Figure 18, it is assumed that the first information includes SR: the terminal multiplexes the PUCCH resource corresponding to the SR to transmit the perception request and the SR, or the terminal multiplexes the PUCCH resource corresponding to the perception request to transmit the perception request and the SR.

As shown in (b) of Figure 18, assuming that the first information includes HARQ, and the number of bits of HARQ is 1 bit: the terminal multiplexes the PUCCH resources corresponding to HARQ to transmit the perception request and HARQ, or the terminal multiplexes the PUCCH resources corresponding to the perception request to transmit the perception request and HARQ.

Optionally, in this case, the terminal may also send a perception request separately.

Case 3: The format of the first PUCCH resource is the third format.

In case 3, the implementation process of the terminal multiplexing the first PUCCH resource to transmit the perception request and the first information may include: the terminal directly multiplexing the first PUCCH resource to transmit the perception request and the first information. The first information includes at least one of HARQ, SR, or CSI

Optionally, when the format of the first PUCCH resource is the third format, since the amount of transmission data corresponding to the third format is large, even if the terminal transmits the perception request and the first information normally on the first PUCCH resource, it will not affect the stability of the information transmission, thereby ensuring the stability of the transmission of the perception request and the first information.

Optionally, in this case, the terminal may also send a perception request separately.

In addition, since the number of bits that can be transmitted by the first PUCCH resource is higher when the format of the first PUCCH resource is the third format, in situation 3, the terminal can also reuse the first PUCCH resource to transmit the second information, wherein the second information includes the type of perception data (sensing type, SET) and/or the quality of service (sensing quality of service, SEQ) of the perception data. That is to say, the terminal can reuse the first PUCCH resource to transmit the perception request, the first information, and the second information, which can further reduce the occupancy rate of the PUCCH resources, thereby further improving the utilization rate of the PUCCH resources.

Exemplarily, the types of perception data may include an environment map type and/or an intrusion detection type.

The service quality of the perceived data may include one or more performance metrics, wherein the one or more performance metrics may include at least one of the following: perceived accuracy, perceived resolution, perceived reliability, perceived range, or perceived latency.

Among them, the perception accuracy is used to indicate the error range of the perception data. The perception accuracy may include at least one of speed perception accuracy, angle perception accuracy, or position perception accuracy. For example, if the speed accuracy is 5 kilometers per hour (kilometers per hour, km/h), the speed accuracy is used to indicate that the speed error is within plus or minus 5 km/h.

The perceptual resolution is used to indicate the minimum granularity of the perceptual data. The perceptual resolution may include at least one of the speed perceptual resolution, the angle perceptual resolution, or the position perceptual resolution. For example, if the speed resolution is 5 km/h, the speed resolution may be used to indicate that the minimum granularity of the recognizable speed is 5 km/h, that is, the difference between the perceived speed values is 5 km/h.

The perceived reliability may include at least one of a recognition probability, a false alarm probability, or a missed detection probability.

The scope of perception is used to indicate the range in which perception operations can be performed.

The perceived delay is used to indicate the maximum acceptable delay for transmitting perceived data.

Regarding the service quality of perception data, different types of perception services may correspond to different quality of service (QoS). For example, when the perception service is an environmental map type, the service quality of perception data may include priority information related to perception accuracy, perception resolution, and perception range; for another example, when the perception service is an intrusion detection type, the service quality of perception data may include priority information related to perception reliability, perception delay, and perception range.

In addition, even in multiple perception services of the same type, different perception services may correspond to different service qualities. For example, as shown in Table 9 below, when perception service 1 is a perception service of an environmental map type for a wild environment and the perception target is a static target, the priority of position perception accuracy is greater than the priority of speed perception accuracy, that is, the priority of position perception accuracy is 1, and the priority of speed perception accuracy is 2. In addition, in this case, the priority of angle perception accuracy may be 2, and the priority of perception range may be 3; for another example, when perception service 2 is a perception service of an environmental map type for an urban environment and most of the perception targets are dynamic targets, the priority of speed perception accuracy is greater than the priority of position perception accuracy.

Table 9

Furthermore, if the number of bits of information transmitted by the terminal using the first PUCCH resource is too large, it may cause problems such as information transmission failure or network congestion. In view of this, when the number of bits of information transmitted by the terminal using the first PUCCH resource is too large, the terminal may discard part of the above-mentioned perception request, the first information, and the second information, and transmit another part of the above-mentioned perception request, the first information, and the second information to ensure the normal transmission of the perception request, the first information, and the second information, and avoid the problem of failure of the transmission of the third information due to congestion as much as possible. However, the implementation method of the terminal discarding part of the above-mentioned perception request, the first information, and the second information may include the following two implementation methods: implementation method 1 is overall discard (drop), and implementation method 2 is packet discard.

Implementation method 1 is to discard the entire message.

In implementation manner 1, the implementation manner in which the terminal discards the above-mentioned perception request, the first information, and part of the second information may be: when the number of bits of the third information is greater than the first number of bits, the terminal discards part of the third information. The third information includes the perception request, the first information, and the second information. The first number of bits is determined based on the first PUCCH resource and the code rate.

In this implementation method 1, the terminal will discard the next type of information only after discarding one type of information. For example, as shown in (a) in Figure 19, the terminal will discard at least one of the service quality of the perceived data #1, the service quality of the perceived data #2, and the service quality of the perceived data #3 only after discarding CSI-part2#1, CSI-part2#2, and CSI-part2#3.

Further, optionally, before the terminal discards the above-mentioned partial information, the terminal may sort the information in the third information based on the priority of the information included in the third information, and determine partial information from the sorted third information, so that partial information with lower priority can be discarded from the third information, so as to avoid the operation of discarding partial information from causing a greater impact on the communication network, thereby ensuring the normal operation of the communication network as much as possible.

Optionally, the priority of any information in the first information is higher than the priority of the perception request. Exemplarily, assuming that the third information includes: perception request, type of perception data, quality of service of perception data, HARQ, SR, CSI-part1, and CSI-part2: the priority order of the information included in the third information is HARQ-SR-CSI-part1-CSI-part2-perception request-type of perception data-quality of service of perception data (recorded as order 1). It can be seen from the above that HARQ, SR, CSI-part1, and CSI-part2 are all information in the first information, and the priority of the above HARQ, SR, CSI-part1, and CSI-part2 are all higher than the priority of the perception request, that is, the priority of all information in the first information is higher than the priority of the perception request.

Optionally, the priority of some information in the first information is higher than the priority of the perception request. Exemplarily, assuming that the third information includes: perception request, type of perception data, quality of service of perception data, HARQ, SR, CSI-part1, and CSI-part2: the priority order of the information included in the third information is HARQ-SR-CSI-part1-perception request-type of perception data-CSI-part2-quality of service of perception data (recorded as order 2). It can be seen from the above that HARQ, SR, CSI-part1, and CSI-part2 are all information in the first information, and the priority of HARQ, SR, and CSI-part1 are higher than the priority of the perception request, while the priority of CSI-part2 is lower than the priority of the perception request, that is, only some of the information in the first information has a higher priority than the priority of the perception request.

Optionally, the above provides two priority sorting rules for sorting the information in the third information, so that the terminal can adaptively sort the information in the third information based on the actual situation, so that the partial information determined later can be more in line with the actual situation. For example, in the case where the perceived information can better improve the network performance of the communication network, the terminal can sort the information included in the third information based on the above order 2, and in the case where the perceived information cannot better improve the network performance of the communication network, the terminal can sort the information included in the third information based on the above order 1.

Optionally, the number of bits of some information in implementation method 1 needs to be greater than or equal to the difference between the number of bits of the third information and the first number of bits, and the first number of bits is determined based on the first PUCCH resource and code rate. This can effectively avoid problems such as information transmission failure or network congestion.

In addition, the bit rate of implementation mode 1 refers to the bit rate configured for the third information, wherein the bit rate configured for the third information may be the same as the bit rate configured for the perception requirement, the bit rate configured for the third information may be the same as the bit rate configured for the first information, and the bit rate configured for the third information may be the same as the bit rate configured for the second information. However, the bit rate configured for the perception requirement, the bit rate configured for the first information, and the bit rate configured for the second information may be the same or different, and the embodiment of the present application does not impose any limitation on this.

Implementation method 2 is packet discard.

In implementation mode 2, the implementation mode in which the terminal discards the above-mentioned perception request, the first information, and part of the information in the second information can be: the terminal can divide the third information into multiple information groups, and discard part of the information in the information group when the number of bits of any one of the above-mentioned multiple information groups is greater than the third number of bits corresponding to the information group, wherein the third information includes the perception request, the first information, and the second information. Each of the multiple information groups includes at least one piece of information in the third information. The third number of bits is determined based on the transmission resources and code rate configured for the information group. In this implementation mode 2, the terminal discards different types of information in sequence. For example, as shown in (b) of Figure 19, CSI-part2 is an information group, and the quality of service of the perception data is an information group, so that the terminal can discard the quality of service #1 of the perception data after discarding CSI-part2#1, and discard the quality of service #2 of the perception data after discarding CSI-part2#2, and discard the quality of service #3 of the perception data after discarding CSI-part2#3.

In an example, assuming that the third information includes: perception request, type of perception data, quality of service of perception data, HARQ, SR, CSI-part1, and CSI-part2: the above-mentioned multiple information groups can be the following three information groups: information group 1 includes HARQ, SR, and CSI-part1, information group 2 includes CSI-part2, and information group 3 includes perception request, type of perception data, and quality of service of perception data.

As another example, assuming that the third information includes: perception request, type of perception data, quality of service of perception data, HARQ, SR, CSI-part1, and CSI-part2: the above-mentioned multiple information groups can be the following 2 information groups: information group 4 includes HARQ, SR, CSI-part1, and CSI-part2, and information group 5 includes perception request, type of perception data, and quality of service of perception data.

As another example, assuming that the third information includes: perception request, type of perception data, quality of service of perception data, HARQ, SR, CSI-part1, and CSI-part2: the above-mentioned multiple information groups can be the following 2 information groups: information group 8 includes HARQ, SR, CSI-part1, perception request, and type of perception data, and information group 9 includes CSI-part2 and quality of service of perception data.

As another example, assuming that the third information includes: perception request, type of perception data, quality of service of perception data, HARQ, SR, CSI-part1, and CSI-part2: the above-mentioned multiple information groups can be the following 2 information groups: information group 6 includes HARQ, SR, and CSI-part1, and information group 7 includes CSI-part2, perception request, type of perception data, and quality of service of perception data.

Of course, the above is an exemplary description of multiple information groups, and multiple information groups may also be divided in other ways, and the embodiments of the present application do not impose any limitations on this.

In addition, when the number of bits of information transmitted by the terminal multiplexing the first PUCCH resource is too large, the terminal may further independently encode each of the multiple information groups, which may improve the coding gain.

Furthermore, optionally, before the terminal discards the above-mentioned partial information, the terminal can sort the information in the information group based on the priority of the information included in the information group, and determine partial information from the sorted information group. This can avoid the discarded partial information from causing a greater impact on the communication network, thereby ensuring the normal operation of the communication network as much as possible.

Optionally, the priority of the information included in the information group can be understood by referring to the priority of the information included in the third information, which will not be described in detail here.

Optionally, the number of bits of the partial information in implementation mode 1 needs to be greater than or equal to the difference between the number of bits of the information group and the third number of bits, which can effectively avoid problems such as information transmission failure or network congestion.

In addition, the code rate of implementation method 1 refers to the code rate configured for the information group, wherein the code rates configured for different information groups can be the same or different, and the embodiments of the present application do not impose any restrictions on this.

After the type of the sensing data or the service quality of the sensing data is discarded, the terminal may transmit the preconfigured type of the sensing data or the preconfigured service quality of the sensing data.

Optionally, after the terminal encodes the information (e.g., the perception request, the first information, the second information, or the third information), the terminal may preferentially map the encoded information to a symbol that is closer to the symbol carrying the DMRS. For example, as shown in FIG. 20, the symbol carrying the DMRS includes symbol 3 and symbol 10, so that the terminal may preferentially map the encoded information to symbol 2, or symbol 4, or symbol 9, or symbol 11, so as to ensure the reliability of the information as much as possible. After that, if the encoded information has not been mapped, the terminal may map the remaining encoded information to other remaining symbols.
