technical field

The present application relates to the field of communication, and more particularly, to a method and a communication device for transmitting uplink information.

Background technique

During uplink transmission in a communication system, at least one of a physical uplink control channel (PUCCH) transmission and a transmission block (TB) carrying the same transmission block (TB) may be simultaneously configured in a time slot (slot). Physical uplink shared channel (PUSCH) transmission.

SUMMARY OF THE INVENTION

The present application provides a method and a communication device for transmitting uplink information, which can multiplex uplink control information on an uplink data channel for transmission, thereby improving transmission reliability and system efficiency.

In a first aspect, a method for transmitting uplink information is provided, and the method can be executed by a terminal device or a module (eg, a chip) in the terminal device.

The method includes: determining a first time-frequency resource and uplink control information carried on an uplink control channel to be sent thereon; determining a second time-frequency resource and N uplink data channels to be sent thereon, the N uplink data channels The same transport block is carried on the network, and N is an integer greater than 1. In the case where the first time-frequency resource and the second time-frequency resource overlap in the time domain, if there is an uplink data channel that satisfies the first condition in the N uplink data channels, the uplink control information is carried in the first time-frequency resource. sent on the target channel. Wherein, the first target channel is an uplink data channel among the N uplink data channels that satisfies a first condition, and the first condition is a timeline condition for multiplexing uplink control information on the uplink data channel for transmission.

Therefore, based on the method for transmitting uplink information provided by the present application, as long as there are uplink data channels in the N uplink data channels that satisfy the timeline condition for the transmission of uplink control information multiplexing on the uplink data channel, all uplink data channels are not required. If the channels all satisfy the timeline condition, the uplink control information that should be carried on the uplink control channel can be transmitted on the uplink data channel that satisfies the timeline condition that the uplink control information is multiplexed on the uplink data channel for transmission. Therefore, the problem of discarding uplink control information in the prior art can be avoided, thereby improving transmission reliability and improving system efficiency. In addition, since there is no need to perform retransmission scheduling of uplink control information, scheduling signaling overhead can be reduced.

It should be understood that the overlapping of "A" and "B" in the time domain or the overlapping of "A" and "B" described in this application may include that "A" and "B" partially overlap in the time domain and "A" and "B" B" completely overlaps both cases in the time domain. That is to say, whether "A" and "B" completely overlap in the time domain or "A" and "B" partially overlap in the time domain, the method provided in this application can be adopted.

In this application, the time line condition for multiplexing the uplink control information on the uplink data channel for transmission, that is, the first condition, refers to: (1) The uplink control channel and the uplink data channel that overlap in the time domain are the earliest in time. The time interval between the first orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol of the channel and the end time of the downlink data channel is not less than the first threshold. Wherein, any one of the uplink data channel and the uplink control channel corresponds to the downlink data channel, that is, the uplink control channel or the uplink data channel carries the feedback information of the downlink data channel. (2) The time interval between the first OFDM symbol of the earliest channel in time among the uplink control channel and the uplink data channel that overlap in the time domain and the end time of the downlink control channel is not less than the second threshold. Wherein, any one of the uplink data channel and the uplink control channel corresponds to the downlink control channel, which means that the downlink control channel schedules the downlink data channel, and the uplink control channel or the uplink data channel carries the downlink data channel. feedback information; or, the downlink control channel schedules uplink data channel transmission. In the above, the first threshold may be N1+X OFDM symbols, and the second threshold may be N2+Y OFDM symbols. Among them, N1 represents the processing time of the terminal device for the downlink data channel, that is, the time for the terminal device to demodulate and decode the downlink data channel after receiving the downlink data channel, and generate feedback information to prepare for sending. N2 represents the preparation time of the terminal equipment for the uplink data channel, that is, the time when the terminal equipment demodulates and decodes the signaling after receiving the scheduling information of the uplink data channel, and prepares the uplink data channel packet for sending according to the signaling. X and Y are pre-configured, predefined or the number of OFDM symbols indicated by the network device. It should be understood that if the uplink control channel or the uplink data channel needs to be scheduled or activated by the downlink control channel, the uplink control channel and the uplink data channel need to satisfy the above two conditions at the same time. If the uplink control channel or the uplink data channel is free of scheduling or activation, only the first condition needs to be satisfied.

With reference to the first aspect, in some implementations of the first aspect, there are also uplink data channels that do not meet the first condition in the N uplink data channels.

Based on this solution, in a scenario where both the uplink data channels that do not meet the first condition and the uplink data channels that satisfy the first condition exist in the N uplink data channels, the uplink control information can be carried on the uplink data channels that satisfy the first condition transmitted on the data channel. Therefore, the problem of discarding the uplink control information or the uplink control channel in the N uplink data channels existing in the prior art can be avoided as long as there are uplink data channels that do not satisfy the first condition, thereby improving the reliability of transmission and improving the system efficiency. . In addition, since there is no need to perform retransmission scheduling of uplink control information, scheduling signaling overhead can be reduced.

With reference to the first aspect, in some implementations of the first aspect, the first target channel is the earliest uplink data channel among all the uplink data channels that satisfy the first condition among the N uplink data channels. In other words, the time-frequency resource that carries the first target channel in the second time-frequency resource is earlier in the time domain than the time-frequency resource that carries any other uplink data channel that satisfies the first condition.

Based on this solution, by carrying the uplink control information on the earliest uplink data channel that satisfies the first condition and sending it, the delay requirement of the uplink control information can be guaranteed as much as possible.

With reference to the first aspect, in some implementations of the first aspect, the method may further include: carrying the uplink control information on at least one second target channel among the N uplink data channels for sending. Wherein, the second target channel is later than the first target channel.

It should be understood that the meaning that the second target channel is later than the first target channel means that the time-frequency resources bearing the second target channel are located after the time-frequency resources bearing the first target channel in the time domain. It can be understood that the uplink data channels after the first target channel in the N uplink data channels all satisfy the first condition.

Based on this solution, by using the inherent repetition of the uplink data channel to repeatedly send the uplink control information, the transmission reliability of the uplink control information can be further improved.

With reference to the first aspect, in some implementations of the first aspect, the second target channel and the uplink control channel overlap in the time domain.

The first target channel is an uplink data channel among the N uplink data channels that satisfies a first condition, and the first condition is a timeline condition for multiplexing uplink control information on the uplink data channel for transmission.

Based on the method for transmitting uplink information provided by the present application, as long as there are uplink data channels in the N uplink data channels that satisfy the timeline condition for multiplexing uplink control information on the uplink data channel for transmission, all uplink data channels do not need to be If all of the time line conditions are satisfied, the uplink control information that should be carried on the uplink control channel can be transmitted on the uplink data channel that satisfies the time line condition that the uplink control information is multiplexed and transmitted on the uplink data channel.

Wherein, the multiple uplink control channels are used to transmit the same uplink control information. The multiple uplink control channels are in one-to-one correspondence with multiple time units, that is, each time unit can transmit one uplink control channel. The uplink data channel and the first uplink control channel of the plurality of uplink control channels belong to the same time unit, or in other words, the time-frequency resource carrying the uplink data channel and the time-frequency resource carrying the first uplink control channel are in the time domain belong to the same time unit.

Through the above method, it is possible to realize the transmission of the uplink data channel and the uplink control information in the scenario where the uplink data channel and the uplink data channel are repeatedly transmitted in the time domain.

In a fifth aspect, a method for transmitting uplink information is provided, and the method can be executed by a terminal device or a module (eg, a chip) in the terminal device.

The method includes: determining service information of uplink control information to be sent on an uplink control channel; determining service information of each uplink data channel in the M uplink data channels; according to the service information of the uplink control information and the service information of each uplink data channel The service information is used to determine the target uplink data channel from the M uplink data channels; the uplink control information is carried on the target uplink data channel for transmission.

The service information is service type or priority. The service information of at least two of the M uplink data channels is different. Moreover, each uplink data channel overlaps with the uplink control channel in the time domain, and the meaning of the overlap is the same as the meaning of the overlap described above, and will not be repeated here. Moreover, the M uplink data channels and the uplink control channel belong to the same time unit, and the meaning of the time unit is the same as the overlapping meaning described above, and will not be repeated here.

Specifically, in the case where the uplink control channel overlaps with multiple uplink data channels, the terminal device may, according to the service type of the uplink control information originally carried on the uplink control channel and the service type of each uplink data channel, or according to the The priority of the uplink control information and the priority of each uplink data channel determine the uplink data channel multiplexed by the uplink control information. Therefore, the terminal device can discard the uplink control channel, and transmit the uplink control information on the uplink data channel multiplexed by the uplink control information.

In the method for transmitting uplink information provided by the present application, by determining the uplink data channel multiplexed by the uplink control information according to the service type or priority, it is possible to carry out a more reasonable operation when the uplink control channel overlaps with multiple uplink data channels. transmission. For example, the transmission of information with higher priority can be guaranteed as much as possible, or the transmission of services with higher reliability and delay requirements can be guaranteed as much as possible, or the transmission of uplink control information can be guaranteed as much as possible, so that network devices can obtain timely information. Feedback information transmitted.

Optionally, for the representation or indication manner of the priority of the uplink control information and the uplink data channel, reference may be made to the above description of the priority of the uplink control information and the uplink data channel, which will not be repeated here.

Optionally, the service type of the uplink data channel can be indicated by any one of the following information:

(1) The time unit length of uplink data channel scheduling. That is, the time unit length of the uplink data channel scheduling may indicate the service type of the uplink data channel.

For example, if the time unit of uplink data channel scheduling is mini-slot, it is considered that the service type of the uplink data channel is ultra reliable and low latency communications (URLLC), and if the time unit of uplink data channel scheduling is time slot, it can be considered that the service type of the uplink data channel is enhanced mobile broadband (enhanced mobile broadband, eMBB).

(2) Scrambling the RNTI that schedules the downlink control information of the uplink data channel. That is, the type of RNTI that scrambles the downlink control information for scheduling the uplink data channel may indicate the service type of the uplink data channel.

For example, if the RNTI of the downlink control information of the scrambled and scheduled uplink data channel is the first RNTI, it is considered that the service type of the uplink data channel is URLLC. The first RNTI may be, for example, a modulation and coding scheme-cell-radio network temporary identifier (modulation and coding scheme-cell-radio network temporary identifier, MCS-C-RNTI) or a configured scheduling radio network temporary identifier (CS) -RNTI). If the RNTI of the downlink control information of the scrambled and scheduled uplink data channel is the second RNTI, it is considered that the service type of the uplink data channel is eMBB. Wherein, the type of the second RNTI is different from that of the first RNTI. The second RNTI may be, for example, a cell radio network temporary identifier (cell radio network temporary identifier, C-RNTI).

(3) Schedule the payload size of the downlink control information of the uplink data channel. That is, the load size of the downlink control information for scheduling the uplink data channel may indicate the service type of the uplink data channel.

For example, if the downlink control information load size of the scheduled uplink data channel #1 is smaller than the downlink control information load size of the scheduled uplink data channel #2, it is considered that the uplink data channel #1 is the URLLC service and the uplink data channel #2 is the eMBB service. For another example, if the load size of the downlink control information of the scheduling uplink data channel #1 is greater than or equal to a predetermined threshold, the service type of the uplink data channel is considered to be eMBB, otherwise it is URLLC.

(4) The MCS table used by the uplink data channel. That is, the MCS table used by the uplink data channel may implicitly indicate the service type of the uplink data channel.

For example, if the MCS table with low spectral efficiency is used for the uplink data channel, it is considered that the service type of the uplink data channel is URLLC. If the uplink data channel uses an MCS table with high spectral efficiency, or contains an MCS table with a modulation mode of 256 quadrature amplitude modulation (quadrature amplitude modulation, QAM), it is considered that the service type of the uplink data channel is eMBB.

(5) Schedule a certain DCI field in the downlink control information of the uplink data channel. That is, the service type of the uplink data channel can be indicated by a value in a DCI field in the downlink control information of the scheduling uplink data channel. The DCI field may contain one bit or multiple bits.

The indication method of the service type of the uplink control information is similar to the indication method of the service type of the uplink data channel. The difference is that the service type of the uplink control information can be the service type of the downlink data channel corresponding to the uplink control information. The meaning corresponding to the data channel is that the uplink control information includes the feedback of the downlink data channel. At this time, the meaning here of the downlink control information for scheduling the uplink control channel is the downlink control information for scheduling the downlink data channel.

It should be understood that determining the service type of the uplink data channel may be replaced by determining any one of the above (1) to (5). Similarly, determining the service type of the uplink control information may be replaced by determining any one of (1) to (5) above.

In this application, the PUSCH is used as the uplink data channel, the physical downlink share channel (PDSCH) is used as the downlink data channel, the PUCCH is used as the uplink control channel, and the physical downlink control channel (PDCCH) is used as the downlink control channel. The uplink control information (uplink control information, UCI) is used as the uplink control information, and the downlink control information (downlink control information, DCI) is used as the downlink control information. The specific names of the channel, the uplink control information and the downlink control information are not limited, and may have different names in different systems.

A technology is known. In a time slot (slot), if the PUCCH and at least one PUSCH carrying the same transmission block (TB) overlap in the time domain, and the at least one PUSCH satisfies the UCI multiplexing on the PUSCH If the time line condition for transmission on the PUSCH is met, the UCI originally carried on the PUCCH transmission is carried on the PUSCH for transmission, and the PUCCH is not transmitted.

The time line conditions for UCI multiplexing on PUSCH for transmission refer to: (1) the time between the first OFDM symbol of the earliest channel in time in the overlapping PUCCH and PUSCH in the time domain and the end time of PDSCH The interval is not less than the first threshold. Wherein, any one of the PUSCH and the PUCCH corresponds to the PDSCH, that is, the feedback information of the PDSCH is carried on the PUCCH or the PUSCH. (2) The time interval between the first OFDM symbol of the earliest channel in time in the overlapping PUCCH and PUSCH in the time domain and the end time of the PDCCH is not less than the second threshold. Wherein, any one of the PUSCH and the PUCCH corresponds to the PDCCH, which means that the PDCCH schedules the PDSCH, and the PUCCH or the PUSCH carries the feedback information of the PDSCH. Or the PDCCH schedules PUSCH transmission. In the above, the first threshold may be N1+X OFDM symbols, and the second threshold may be N2+Y OFDM symbols. Wherein, N1 represents the processing time of the PDSCH by the terminal device, that is, the time during which the terminal device demodulates and decodes the PDSCH after receiving the PDSCH and generates feedback information and prepares to send it. N2 represents the preparation time for the PUSCH by the terminal device, that is, the time when the terminal device demodulates and decodes the signaling after receiving the scheduling information of the PUSCH, and prepares the PUSCH packet for transmission according to the signaling. X and Y are pre-configured, predefined or the number of OFDM symbols indicated by the network device.

Figure 2 shows a schematic diagram of the timeline conditions for UCI multiplexing for transmission on PUSCH. Referring to FIG. 2 , the earlier channel in time among the PUCCH and PUSCH overlapping in the time domain is PUCCH, and the time interval between the first OFDM symbol of PUCCH and the end time of PDSCH is not less than N1+X OFDM symbols, The time interval from the PDCCH end time is not less than N2+Y OFDM symbols.

Exemplarily, assuming that the positions of PUCCH and PUSCH in the time domain are shown in Figure 3, then both PUSCH#1 and PUSCH#2 need to satisfy the above timeline conditions, so that the uplink control information carried on PUCCH can be carried on PUSCH# 1 to send.

It should be understood that if PUCCH or PUSCH needs PDCCH scheduling or activation, the PUCCH and PUSCH need to satisfy the above two conditions at the same time. If the PUCCH or PUSCH is free of scheduling, only the first condition needs to be satisfied.

Based on the above protocol, if there is a PUSCH that does not meet the above timeline conditions in the at least one PUSCH, for example, PUSCH #1 in FIG. 3 does not meet the timeline conditions and PUSCH #2 meets the timeline conditions, then the PUCCH cannot be transmitted on the PUSCH The uplink control information carried on the network will reduce the reliability of transmission and the system efficiency.

In view of this, the present application provides a method for transmitting uplink information. Based on this method, as long as there is a PUSCH that satisfies the timeline conditions, the uplink control information carried on the PUCCH can be transmitted on the PUSCH without requiring all PUSCHs to be transmitted. Satisfying the timeline conditions can avoid the problem of discarding uplink control information in the prior art, thereby improving transmission reliability and system efficiency.

The method for transmitting uplink information provided by the present application will be described below. It should be understood that, for ease of understanding, when describing the method below, some step operations are mainly described with the terminal device as the execution body, and other operations are mainly described with the network device as the execution body, but this does not constitute any limitation to this application. Above, the operations performed by the terminal device may also be performed by a module (eg, a chip) in the terminal device, and similarly, the operations performed by the network device may also be performed by a module (eg, a chip) in the network device.

The method of the present application can be applied in any time unit, that is, in any time unit, both the terminal device and the network device can transmit uplink control information based on the method. The time unit may be a subframe, a time slot (slot), a half time slot, etc. The specific length of the time unit is not limited in this application. Exemplarily, the time unit may include 14 OFDM symbols or 7 OFDM symbols, and the present application does not limit the number of OFDM symbols included in the time unit. In the following, the time slot is taken as an example for description.

FIG. 4 shows an exemplary flowchart of a method 200 for transmitting uplink information provided by the present application. The method 200 mainly includes S210 to S250. Each step will be described below.

S210, the terminal device determines the first time-frequency resource. The first time-frequency resource is used for sending PUCCH, and the PUCCH is used to carry UCI.

It should be understood that the UCI in the present application may include feedback information, that is, hybrid automatic repeat request (hybrid automatic repeat request, HARQ) feedback information, but the present application is not limited thereto. For example, the UCI may further include a scheduling request (scheduling request, SR) and channel state information (channel statement information, CSI), where the CSI includes periodic CSI (periodic-CSI) and aperiodic CSI (aperiodic-CSI).

Exemplarily, the first time-frequency resource may be configured by the network device to the terminal device in any of the following two manners.

1. The first time-frequency resource may be indicated by trigger signaling. Correspondingly, the PUCCH may be an aperiodic signal triggered by the trigger signaling.

The trigger signaling is DCI or a downlink data channel, the DCI can be carried by a downlink control channel, and the DCI can schedule the downlink data channel. Correspondingly, the UCI carried on the PUCCH is uplink feedback information corresponding to the downlink data channel, such as an acknowledgement (acknowledgement, ACK) or a negative acknowledgement (negative acknowledgement, NACK).

2. The first time-frequency resource may be configured by configuration signaling. Correspondingly, the PUCCH may be a periodic signal configured by the signaling configuration.

The configuration signaling may be RRC signaling or MAC signaling or physical layer signaling. The configuration signaling may configure a transmission period and a time domain resource offset of a periodic signal, and the periodic signal may be a grant-free PUCCH or a semi-persistent scheduling uplink control channel SPS PUCCH. That is, the PUCCH may be grant-free PUCCH or SPS PUCCH.

S220, the terminal device determines the second time-frequency resource.

The second time-frequency resource is used for sending N PUSCHs, and N is an integer greater than 1. The N PUSCHs carry the same transport block, or in other words, the N PUSCHs are used to transmit the same transport block. That is, the N PUSCHs are used for repeated transmission of the same transport block. Moreover, the second time-frequency resource and the first time-frequency resource belong to the same time unit, and the first time-frequency resource and the second time-frequency resource overlap.

The time domain length of each PUSCH may be granular in sub-time unit (or referred to as micro-time unit). The time domain length of the sub-time unit is smaller than the time unit. The sub-time unit may be a micro sub-frame or a mini-slot or other possible time units. Further, when the time unit is a time slot, the sub-time unit may be a mini-slot (mini-slot). When the time unit is a subframe, the sub-time unit may be a micro-subframe. The typical value of the mini-slot is 2, 4, 7 OFDM symbols, and may also be {1, 3, 5, 6, 8, 9, 10, 11, 12, 13} OFDM symbols. In the following, the sub-time unit is taken as an example of a mini-slot for description.

Exemplarily, the network device may configure the number of mini-slot repetitions and the occupied resources for the terminal device through trigger signaling or through configuration signaling. The resources occupied by each mini-slot can be the same value or different values. The amount of resources occupied by each mini-slot can be indicated by a value. Alternatively, the number of resources occupied by each mini-slot may be indicated by a set of values, which may all be the same, or different from each other, or partially different.

The first time-frequency resource and the second time-frequency resource overlap in the time domain, which may mean that the first time-frequency resource and the second time-frequency resource completely overlap in the time domain, or may refer to the first time-frequency resource and the second time-frequency resource. The time-frequency resources partially overlap in the time domain.

Completely overlapping means that the second time-frequency resource includes the first time-frequency resource, and the first time-frequency resource also includes the second time-frequency resource. For example, FIG. 5 shows a case where the first time-frequency resource and the second time-frequency resource completely overlap. Among them, in FIG. 5 and FIG. 6 to FIG. 8 described below, it is assumed that the second time-frequency resource is the sum of the time-frequency resources occupied by PUSCH#1 to PUSCH#4, that is, the N PUSCHs are PUSCH#1 to PUSCH#1 to PUSCH#4, the first time-frequency resource is the time-frequency resource occupied by the PUCCH.

Partial overlap can include three situations: (1) The first time-frequency resource does not include all of the second time-frequency resource, and the second time-frequency resource does not include all of the first time-frequency resource, as shown in Figure 6; ( 2) The first time-frequency resource includes all of the second time-frequency resource, but some time-frequency resources in the first time-frequency resource do not belong to the second time-frequency resource, that is, the second time-frequency resource is the first time-frequency resource. The proper subset is shown in FIG. 7 ; (3) the first time-frequency resource is a proper subset of the second time-frequency resource, as shown in FIG. 8 . It should be understood that the relationship between the time-frequency resources described here only refers to the relationship in the time domain, and is not limited in the frequency domain.

Exemplarily, the network device may configure the second time-frequency resource to the terminal device through a method similar to configuring the first time-frequency resource. It should be noted that, if the time-frequency resources occupied by each PUSCH are the same, the network device may configure the second time-frequency resources by configuring the time-frequency resources occupied by one of the PUSCHs and the number of repeated transmissions. The number of repetitions of the PUSCH, that is, the value of N, may be carried on the DCI, or may be pre-configured by a network device. If the time-frequency resources occupied by each PUSCH are different or the time-frequency resources occupied by at least two PUSCHs are different, the network device may notify the terminal device of the time-frequency resources occupied by each PUSCH respectively. The present application does not limit the configuration mode of the second time-frequency resource, as long as the configuration mode is reasonable.

It should be understood that the time sequence of S210 and S220 is not specified, and S210 may be performed prior to S220, S220 may be performed prior to S210, or both may be performed simultaneously.

S230, the network device determines the first time-frequency resource.

S240, the network device determines the second time-frequency resource.

It should be understood that at this time, what the network device determines is the first time-frequency resource and the second time-frequency resource that have been configured to the terminal device.

S250, the terminal device carries the UCI on the first target channel to send. Accordingly, the network device receives the UCI on the first target channel.

Specifically, in the case where the first time-frequency resource and the second time-frequency resource completely overlap or partially overlap in the time domain, if there is a PUSCH that satisfies the first condition in the N PUSCHs, the terminal device can discard the PUCCH, The UCI that should be carried on the PUCCH is carried on the first target channel for transmission. Wherein, the first target channel is one PUSCH among the N PUSCHs that satisfies the first condition, and the first condition is a timeline condition for UCI multiplexing on the PUSCH for transmission.

That is to say, when the first time-frequency resource and the second time-frequency resource overlap in the time domain, the UCI can be carried in one of the N PUSCHs that satisfies the timeline condition for multiplexing the UCI on the PUSCH for transmission transmitted on PUSCH. Regarding the timeline conditions for the transmission of UCI multiplexing on the PUSCH, reference may be made to the foregoing description for details, and details are not repeated here.

Therefore, based on the method of the present application, as long as there are PUSCHs in the N PUSCHs that satisfy the timeline conditions for UCI multiplexing and transmission on the PUSCH, and all PUSCHs do not need to satisfy the timeline conditions, the PUSCH can be transmitted on the PUSCH. The UCI carried on the PUCCH. Therefore, the problem of discarding the UCI in the prior art can be avoided, thereby improving the reliability of transmission and improving the system efficiency. In addition, since retransmission scheduling of UCI is not required, scheduling signaling overhead can be reduced.

It should be noted that, in this application, the transmission methods of UCI multiplexing on the PUSCH may be two types: puncturing (preemption) and rate-matching (rate-matching).

The following mainly combines two scenarios to describe the possible situation of the first target channel.

scene one

The first target channel may not overlap with the PUCCH in the time domain.

In other words, the time-frequency resource carrying the first target channel in the second time-frequency resource may not overlap with the first time-frequency resource in the time domain.

In this scenario, the first target channel may be any PUSCH that satisfies the first condition among the N PUSCHs. Alternatively, the first target channel may be the earliest PUSCH among all PUSCHs that satisfy the first condition among the N PUSCHs, that is, the time-frequency resource that bears the first target channel in the second time-frequency resource is earlier than the time-frequency resource that bears the first target channel in the time domain. Time-frequency resources of any other PUSCH in the first condition.

For example, referring to FIG. 9 , if the N PUSCHs are PUSCH#1 to PUSCH#4, and among PUSCH#1 to PUSCH#4, only PUSCH#3 and PUSCH#4 satisfy the first condition, then the first target channel may be PUSCH#3 may also be PUSCH#4. Alternatively, the first target channel may be the earliest PUSCH among PUSCH#3 and PUSCH#4, that is, PUSCH#3.

For another example, referring to FIG. 10 , the N PUSCHs are PUSCH#1 to PUSCH#4. If PUSCH#1 to PUSCH#4 all satisfy the first condition, the first target channel may be PUSCH#1, that is, the first condition is satisfied. The earliest PUSCH.

scene two

The first target channel overlaps the PUCCH in the time domain.

In other words, the time-frequency resource carrying the first target channel in the second time-frequency resource overlaps with the first time-frequency resource in the time domain.

In this scenario, the first target channel may be any PUSCH among all the N PUSCHs that overlap with the PUCCH (or the first time-frequency resource) in the time domain and satisfy the first condition. Alternatively, the first target channel may be the earliest PUSCH among all the PUSCHs that overlap with the PUCCH in the time domain and satisfy the first condition among the N PUSCHs.

For example, referring to FIG. 11 , among PUSCH#1 to PUSCH#4, only PUSCH#2 and PUSCH#3 overlap with PUCCH. If both PUSCH#2 and PUSCH#3 satisfy the first condition, the first target channel may be PUSCH#2 or PUSCH#3. Alternatively, the first target channel may be the earliest PUSCH among PUSCH#2 and PUSCH#3, that is, PUSCH#2.

It should be noted that, in this application, there may also be PUSCHs that do not satisfy the first condition in the N PUSCHs, but this application does not limit this. That is to say, in the case where all of the N PUSCHs satisfy the first condition, the present application is also applicable.

In some of the above implementation manners, by carrying the UCI on the earliest PUSCH that satisfies the first condition and sending it, the delay requirement of the UCI can be guaranteed as much as possible.

Optionally, as an embodiment of the present application, S250 may be performed when the priority of the UCI is lower than or equal to the priority of the PUSCH.

That is to say, when the priority of the UCI is lower than or equal to the priority of the PUSCH, the method of the present application can be used to send the UCI. For example, when the UCI of the ultra reliable and low-latency communications (URLLC) service is transmitted on the PUCCH, and the enhanced mobile broadband (eMBB) service is transmitted on the PUSCH, the UCI of this application can be used. method to send the UCI. It should be understood that the priority of the UCI can also be regarded as the priority of the PUCCH.

In this application, optionally, the priority of the PUSCH can be indicated by any one of the following information:

(1) Length of time unit for PUSCH scheduling. That is, the time unit length of the PUSCH scheduling may indicate the priority of the PUSCH.

For example, if the time unit of PUSCH scheduling is a mini-slot, the priority of the PUSCH is considered to be higher, and if the time unit of the PUSCH scheduling is a time slot, the priority of the PUSCH may be considered to be lower.

(2) Scrambling the RNTI of the DCI that schedules the PUSCH. That is, the type of RNTI that scrambles the DCI that schedules the PUSCH may indicate the priority of the PUSCH.

For example, if the RNTI of the scrambled and scheduled DCI of the PUSCH is the first RNTI, it is considered that the PUSCH has a higher priority. The first RNTI may be, for example, a modulation and coding scheme-cell-radio network temporary identifier (modulation and coding scheme-cell radio network temporary identifier, MCS-C-RNTI) or a configured scheduling radio network temporary identifier (CS- RNTI) If the RNTI of the scrambled and scheduled DCI of the PUSCH is the second RNTI, the priority of the PUSCH is considered to be lower. Wherein, the type of the second RNTI is different from that of the first RNTI. The second RNTI may be, for example, a cell radio network temporary identifier (cell radio network temporary identifier, C-RNTI).

(3) The payload size of the DCI for scheduling the PUSCH. That is, the load size of the DCI scheduling the PUSCH may indicate the priority of the PUSCH.

For example, if the load size of the DCI scheduled for PUSCH#1 is smaller than the load size of the DCI scheduled for PUSCH#2, it is considered that the priority of PUSCH#1 is higher, and the priority of PUSCH#2 is lower. For another example, if the load size of the DCI scheduling PUSCH #1 is greater than or equal to a preset threshold, it is considered that the priority of the PUSCH is lower, otherwise the priority is higher.

(4) The MCS table adopted by PUSCH. That is, the MCS table adopted by the PUSCH may indicate the priority of the PUSCH.

For example, if the PUSCH uses an MCS table with low spectral efficiency, it is considered that the PUSCH has a higher priority. If the PUSCH uses an MCS table with high spectral efficiency, or contains an MCS table with a modulation scheme of 256QAM, it is considered that the PUSCH has a lower priority.

(5) Schedule a certain DCI field in the DCI of the PUSCH. That is, the priority of the PUSCH may be indicated by a value in one of the DCI fields in the DCI that schedules the PUSCH. The DCI field may contain one bit or multiple bits.

The indication method of the UCI priority is similar to that of the PUSCH priority. The difference is that the UCI priority can be the priority of the PDSCH corresponding to the UCI, and the meaning corresponding to the UCI (or PUCCH) and the PDSCH can be referred to the above description. . At this time, the meaning of scheduling the DCI of the PUCCH here is to schedule the DCI of the PDSCH corresponding to the PUCCH.

It should be understood that determining the priority of the PUSCH may be replaced by determining any one of (1) to (5) above. Similarly, determining the priority of the UCI can be replaced by determining any of (1) to (5) above.

Optionally, as an embodiment of the present application, the method may further include:

S260, the terminal device carries the UCI on at least one second target channel for sending. Accordingly, the network device receives the UCI on the at least one second target channel.

Wherein, the at least one second target channel is at least one PUSCH among the N PUSCHs, and the second target channel is later than the first target channel in the time domain, or in other words, the first target channel is earlier in the time domain on the second target channel. It should be understood that the meaning that the second target channel is later than the first target channel means that the time-frequency resources bearing the second target channel are located after the time-frequency resources bearing the first target channel in the time domain. It can be understood that the uplink data channels after the first target channel in the N uplink data channels all satisfy the first condition.

Specifically, in addition to sending the UCI on the first target channel, the terminal device may also send the UCI on the PUSCH following the first target channel, that is, repeatedly sending the UCI.

Therefore, by using the inherent repetition of the PUSCH to repeatedly transmit the UCI, the transmission reliability of the UCI can be further improved.

Exemplarily, the terminal device may send the UCI on each PUSCH after the first target channel among the N PUSCHs, or may send the UCI on a part of the PUSCH after the first target channel.

For example, for a scenario where it is not limited that the first target channel needs to overlap with the PUCCH in the time domain, the terminal device may send UCI on each PUSCH after the first target channel. For another example, for a scenario in which the first target channel needs to overlap with the PUCCH in the time domain, the terminal device may send the UCI on the PUSCH that overlaps with the PUCCH in the time domain after the first target channel, that is, the second target channel. It overlaps with PUCCH in time domain. This is explained in conjunction with FIGS. 9 and 11 described above. In FIG. 9 , if the first target channel is PUSCH#3, the terminal device may also send the UCI on PUSCH#4. In FIG. 11 , if the first target channel is PUSCH#2, the terminal device may also send the UCI on PUSCH#3. It should be understood that in FIG. 11 , further, the terminal device may also send the UCI on PUSCH#4, which is not limited in this application.

In this application, the resources occupied by the UCI on the first target channel and/or the second target channel may be determined by the offset value beta-offset. The beta-offset can be notified to the terminal device by scheduling the DCI of the PUCSH, and can also be configured to the terminal device by high-level parameters.

To sum up, based on the method of the present application, it is not necessary for the N PUSCHs to satisfy the timeline conditions. As long as there are PUSCHs in the N PUSCHs that satisfy the timeline conditions for UCI multiplexing on the PUSCH for transmission, the timeline conditions can be met. Conditionally, the UCI carried on the PUCCH is transmitted on one or more PUSCHs.

In another prior art, when the slot-based PUCCH repetition and the mini-slot-based PUSCH repetition overlap in the time domain, the PUCCH is sent and the PUSCH is discarded and not sent. That is, when multiple mini-slot-based PUSCHs that repeatedly transmit the same data block and multiple slot-based PUCCHs that repeatedly transmit the same UCI overlap in the time domain, the prior art will discard the PUSCH and send the PUCCH. This way of handling reduces the reliability of the transmission. For example, if the URLLC service is transmitted on the PUSCH, or the priority of the service transmitted on the PUSCH is higher than the service transmitted on the PUCCH, the transmission method according to the prior art will reduce the reliability of the transmission of the URLLC service.

Fig. 12 is used as an example for description. The network device may configure repeated PUSCH transmission through trigger signaling or through configuration signaling, that is, multiple PUSCHs repeatedly transmit the same transport block. When a repeated transmission crosses a slot boundary, the cross-boundary PUSCH automatically becomes two PUSCH repeated transmissions. For example, as shown in FIG. 12 , the network device indicates through trigger signaling or configures 4 PUSCH repeated transmissions through configuration signaling, wherein PUSCH#2 and PUSCH#3 are two repeated transmissions divided by the time slot boundary. Thus, PUSCH#1 to PUSCH#5 need to be transmitted. The network device can also indicate through trigger signaling or configure repeated transmission of PUCCH through configuration signaling, for example, repeated transmission of PUCCH in time slot #1 to time slot #4 shown in FIG. 12 , ie, PUCCH #1 to PUCCH #4. It can be seen that in time slot #1 and time slot #2, the time-frequency resources that carry PUSCH and the time-frequency resources that carry PUCCH overlap in the time domain. According to the technology, PUSCH#1 to PUSCH#5 and PUCCH will be discarded Overlapping PUSCHs, ie PUSCH #1, PUSCH #2, PUSCH #4 and PUSCH #5.

The above-described method provided by the present application can solve this problem, thereby avoiding the discarding of the PUSCH and improving the reliability of transmission. Taking FIG. 12 as an example, for time slot #1 and time slot #2, the method described above can be used to carry the UCI that should be carried on the PUCCH on the PUSCH for transmission.

Specifically, for time slot #1, the time-frequency resource carrying PUCCH#1 is the first time-frequency resource above, and the sum of the time-frequency resource carrying PUSCH#1 and the time-frequency resource carrying PUSCH#2 is For the second time-frequency resource above, PUCCH#1 is the PUCCH above, and PUSCH#1 and PUSCH#2 are the N PUSCHs above. It can be seen that the first time-frequency resource and the second time-frequency resource overlap. At this time, if there is a PUSCH that satisfies the first condition in PUSCH#1 and PUSCH#2, the UCI that should be carried on PUCCH#1 may be carried on the first target channel for transmission. It can be known from the foregoing description that the first target channel may be any PUSCH that satisfies the first condition among PUSCH#1 and PUSCH#2, or may be the earliest PUSCH that satisfies the first condition and is among PUSCH#1 and PUSCH#2. Alternatively, the first target channel may be any PUSCH in PUSCH#1 and PUSCH#2 that overlaps with PUCCH in time domain and satisfies the first condition, or may be any PUSCH in PUSCH#1 and PUSCH#2 that overlaps with PUCCH in time domain The earliest PUSCH among the overlapping PUSCHs satisfying the first condition. For example, if PUSCH #2 satisfies the first condition, the UCI may be carried on PUSCH #2 for transmission. For example, if both PUSCH#1 and PUSCH#2 satisfy the first condition, the UCI may be carried on PUSCH#1 for transmission. It should be understood that, in addition to sending UCI on the first target channel, as described above, further, UCI can also be sent on at least one second target channel. The definition of the second target channel is as described above, and details are not repeated here.

Similarly, for time slot #2, the sum of the time-frequency resources carrying PUSCH#3 to PUSCH#5 is the second time-frequency resource above, and the time-frequency resource carrying PUCCH#2 is the first time-frequency resource above. frequency resources, PUSCH#3 to PUSCH#5 are the N PUSCHs above, and PUCCH#2 is the PUCCH above. The first time-frequency resource and the second time-frequency resource overlap, and if there is a PUSCH that satisfies the first condition in PUSCH#3 to PUSCH#5, the UCI may be carried on the first target channel for transmission. Here, the first target channel may be any one of PUSCH #3 to PUSCH #5 that satisfies the first condition, or may be the earliest PUSCH that satisfies the first condition among PUSCH #3 to PUSCH #5. Alternatively, the first target channel may be any PUSCH from PUSCH#3 to PUSCH#5 that overlaps with PUCCH in time domain and satisfies the first condition, or may be PUSCH#3 to PUSCH#5 that overlaps with PUCCH in time domain The earliest PUSCH among the PUSCHs satisfying the first condition. For example, if the first condition is satisfied among PUSCH#3 to PUSCH#5 and the earliest PUSCH is PUSCH#4, the UCI may be carried on PUSCH#4 for transmission. It should be understood that, in addition to sending UCI on the first target channel, as described above, further, UCI can also be sent on at least one second target channel, for example, UCI can also be sent on PUSCH#5. The definition of the second target channel is as described above, and details are not repeated here.

FIG. 13 shows another example in which slot-based PUCCH repetition and mini-slot-based PUSCH repetition overlap in the time domain. Referring to FIG. 13 , the time-frequency resource carrying PUCCH#1 is the first time-frequency resource above, and the sum of the time-frequency resources carrying PUSCH#1 to PUSCH#4 is the second time-frequency resource above, PUCCH# 1 is the PUCCH above, and PUSCH#1 to PUSCH#4 are the N PUSCHs above. It can be seen that in time slot #1, the first time-frequency resource and the second time-frequency resource overlap. Then, for the time slot #1, the method described above may be used to transmit the UCI that should be carried on the PUCCH #1. For details, please refer to the above description, which will not be repeated here.

In addition, the prior art does not address the issue of how to transmit the UCI carried on the PUCCH in a scenario where the time-slot-based PUCCH repeats and the mini-slot-based or time-slot-based PUSCH overlaps in the time domain.

Based on this, the present application also provides a method for transmitting method information. In this method, if the PUSCH overlaps with a certain PUCCH in the PUCCH repetition in the time domain, and the priority of the UCI that should be carried on the PUCCH is not higher than the priority of the PUSCH, then the PUSCH and the PUSCH in the time domain In the case that the PUCCH overlapped with the above satisfies the first condition, the UCI is carried on the PUSCH for transmission. UCI can be transmitted through the solution for transmitting UCI provided in this application.

It should be understood that how to determine the priority of the PUSCH and the priority of the UCI can refer to the above description of the priority of the PUSCH and the priority of the UCI, which will not be repeated here. The first condition can also be found in the previous description.

Specifically, the method may include the following steps:

Step 1, the terminal device determines time-frequency resources that carry multiple PUCCHs.

Wherein, the multiple PUCCHs are used to transmit the same UCI. The multiple PUCCHs are in one-to-one correspondence with multiple time units, that is, each time unit may transmit one PUCCH.

The time-frequency resources bearing multiple PUCCHs may be indicated by the network device through trigger signaling or configured to the terminal device through configuration signaling. It should be understood that the network device may indicate to the terminal device the time-frequency resources bearing the multiple PUCCHs by configuring the time-frequency resources for transmitting one PUCCH and the number of repeated transmissions. In addition, the network device can also indicate to the terminal device the time-frequency resource that bears each PUCCH. This application does not limit how the network device configures the time-frequency resources bearing multiple PUCCHs to the terminal device, as long as the configuration is reasonable.

Step 2, the terminal device determines the time-frequency resource that bears the PUSCH.

The PUSCH and the first PUCCH in the plurality of PUCCHs belong to the same time unit, or in other words, the time-frequency resources that carry the PUSCH and the time-frequency resources that carry the first PUCCH belong to the same time unit in the time domain. The first PUCCH may be any one of the plurality of PUCCHs. In addition, the time-frequency resource carrying the PUSCH overlaps the time-frequency resource carrying the first PUSCH in the time domain. It should be understood that the meaning of overlapping here is the same as the meaning of overlapping described above, and will not be repeated here.

The network device may configure the time-frequency resource bearing the PUSCH to the terminal device through trigger signaling or through configuration signaling. For details, refer to the description of the method 200, which is not repeated here.

Step 3, the network device determines the time-frequency resources bearing the multiple PUCCHs.

Step 4: The network device determines the time-frequency resource that bears the PUSCH.

Step 5: If the priority of the UCI is not higher than the priority of the PUSCH, and the PUSCH satisfies the first condition, the UCI carried on the first PUCCH is carried on the PUSCH for transmission. Accordingly, the network device receives the UCI on the PUSCH.

Specifically, in the case where the priority of the UCI is not higher than the priority of the PUSCH, if the PUSCH and the first PUCCH overlap in the time domain, and the PUSCH and the first PUCCH satisfy the first condition, the current transmission is transmitted on the PUSCH. The UCI carried on the PUCCH, and the first PUCCH is discarded.

To sum up, according to the method for transmitting uplink information provided by this application, in the case where the PUSCH overlaps with a certain PUCCH in the multiple PUCCHs in the time domain, if the priority of the UCI that should be carried on the PUCCH is not higher than that of the PUSCH priority, and the PUSCH and the PUCCH overlapping the PUSCH in the time domain satisfy the first condition, the UCI is carried on the PUSCH for transmission. Through the above method, it is possible to realize the transmission of PUSCH and UCI in a scenario where the repeated transmission of PUSCH and PUSCH overlap in the time domain.

An example is given with reference to FIG. 14 . Referring to FIG. 14 , that is, the network device can configure the terminal device to repeatedly transmit the same information on PUCCH#1 to PUCCH#4, and can configure the terminal device to transmit uplink data on PUSCH#1. It can be seen that PUCCH#1 to PUCCH#4 and PUSCH#1 overlap in the time domain, or in other words, the time-frequency resources for carrying PUCCH#1 to PUCCH#4 and the time-frequency resources for carrying PUSCH#1 are in the time domain overlapped. In this case, if PUSCH#1 satisfies the first condition, the UCI that should be carried on the PUCCH overlapping with PUSCH#1 in the time domain can be carried on PUSCH#1 for transmission, that is, the UCI that should have been carried on the PUCCH in the time domain can be carried on PUSCH#1 for transmission. UCI on PUCCH#2 is carried on PUSCH#1 for transmission, and PUCCH#2 is discarded.

It should be understood that in the method described here, the determination of whether the first condition is satisfied is based on the granularity of time units, that is, in FIG. 14, it is only judged in time slot #2 whether PUSCH #1 meets the first condition, or we only care about The time length between the first symbol of PUSCH#1 and PUCCH#2 and the corresponding PDSCH and PDCCH is not concerned with the time length between other PUCCH and PUSCH and the corresponding PDSCH and PDCCH.

In another scenario, the network device may indicate through trigger signaling or configure through configuration signaling to configure the PUCCH bearing UCI to be transmitted within a time unit, and at the same time transmit multiple PUSCHs within the time unit, at least among the multiple PUSCHs The two PUSCHs are used to carry data of different service types, or the priorities (or referred to as transmission priorities) of the at least two PUSCHs are different, and the PUCCH and each PUSCH in the multiple PUSCHs are both in the time domain. overlapping. For this scenario, how the terminal device transmits the PUSCH and the PUCCH is not covered in the prior art.

Based on this, the present application provides another method for transmitting uplink information. The method will be described below with reference to FIGS. 15 to 22 .

FIG. 15 shows an exemplary flowchart of another method 300 for transmitting uplink information provided by the present application. The method 300 may include S310 to S370. = Each step will be described below.

S310, the terminal device determines the service information of the UCI to be sent on the PUCCH.

S320, the terminal device determines service information of each PUSCH in the M PUSCHs.

The service information is service type or priority. The service information of at least two PUSCHs in the M PUSCHs is different. For example, the service types or priorities of at least two PUSCHs in the M PUSCHs are different. Moreover, each PUSCH overlaps with the PUCCH in the time domain, and the meaning of the overlap is the same as the meaning of the overlap described above, and will not be repeated here. And, the M PUSCHs and the PUCCH belong to the same time unit.

For the representation or indication manner of the priorities of the UCI and the PUSCH, reference may be made to the description of the priorities of the UCI and the PUSCH above, which will not be repeated here. This section mainly introduces how to indicate the service types of PUSCH and PUCCH.

Optionally, the service type of PUSCH can be indicated by any of the following information:

(1) Length of time unit for PUSCH scheduling. That is, the time unit length of the PUSCH scheduling may indicate the traffic type of the PUSCH.

For example, if the time unit of PUSCH scheduling is mini-slot, the service type of PUSCH is considered to be URLLC, and if the time unit of PUSCH scheduling is time slot, the service type of PUSCH may be considered to be eMBB.

(2) Scrambling the RNTI of the DCI that schedules the PUSCH. That is, the type of RNTI that scrambles the DCI that schedules the PUSCH may indicate the traffic type of the PUSCH.

For example, if the RNTI of the scrambled and scheduled DCI of the PUSCH is the first RNTI, it is considered that the service type of the PUSCH is URLLC. The first RNTI may be, for example, an MCS-C-RNTI or a CS-RNTI. If the RNTI of the DCI that scrambles and schedules the PUSCH is the second RNTI, it is considered that the service type of the PUSCH is eMBB. Wherein, the type of the second RNTI is different from that of the first RNTI. The second RNTI may be, for example, a C-RNTI.

(3) The payload size of the DCI for scheduling the PUSCH. That is, the load size of the DCI scheduling the PUSCH may indicate the traffic type of the PUSCH.

For example, if the load size of the DCI scheduled for PUSCH#1 is smaller than the load size of the DCI scheduled for PUSCH#2, it is considered that PUSCH#1 is the URLLC service and PUSCH#2 is the eMBB service. For another example, if the load size of the DCI scheduling PUSCH #1 is greater than or equal to a certain preset threshold, it is considered that the service type of the PUSCH is eMBB, otherwise it is URLLC.

(4) The MCS table adopted by PUSCH. That is, the MCS table adopted by the PUSCH may indicate the service type of the PUSCH.

For example, if the PUSCH uses an MCS table with low spectral efficiency, it is considered that the service type of the PUSCH is URLLC. If the PUSCH uses an MCS table with high spectral efficiency, or contains an MCS table with a modulation mode of 256QAM, it is considered that the service type of the PUSCH is eMBB.

(5) Schedule a certain DCI field in the DCI of the PUSCH. That is, the service type of the PUSCH can be indicated by a value in a graduation field in the DCI that schedules the PUSCH. The DCI field may contain one bit or multiple bits.

The indication method of the service type of UCI is similar to that of the service type of PUSCH, the difference is that the service type of UCI can be the service type of PDSCH corresponding to the UCI, and the meanings corresponding to UCI and PDSCH can be referred to the above description. At this time, the meaning of scheduling the DCI of the PUCCH here is to schedule the DCI of the PDSCH.

It should be understood that determining the service type of the PUSCH may be replaced by determining any one of the above (1) to (5). Similarly, determining the service type of the UCI may be replaced by determining any one of (1) to (5) above.

S330, the terminal device determines the target PUSCH from the M PUSCHs according to the service information of the UCI and the service information of each PUSCH.

The target PUSCH is the PUSCH multiplexed by the UCI, that is, the UCI can be carried on the target PUSCH for transmission.

S340, the network device determines the service information of each PUSCH.

Optionally, the network device may determine the service information of the PUSCH according to the service request from the terminal device.

S350, the network device determines the service information of the UCI.

Optionally, the network device may determine the service information of the UCI according to the service information of the downlink data corresponding to the UCI.

S340 corresponds to S310, and S350 corresponds to S320. For details on how the network device determines the service information of the UCI and the service information of each PUSCH, please refer to the description of S310 and S320 above, which will not be repeated here.

S360, the network device determines the target PUSCH from the M PUSCHs according to the service information of the UCI and the service information of each PUSCH.

If there is a target PUSCH, the method may further include:

S370, the terminal device carries the UCI on the target PUSCH and sends it. Accordingly, the network device receives the UCI on the target PUSCH.

Specifically, in the case where the PUCCH overlaps with multiple PUSCHs, the terminal device may, according to the service type of the UCI originally carried on the PUCCH and the service type of each PUSCH, or according to the priority of the UCI and the priority of each PUSCH stage to determine the PUSCH multiplexed by the UCI. Therefore, the terminal device can discard the PUCCH and transmit the UCI on the PUSCH multiplexed by the UCI.

In the method for transmitting uplink information provided by the present application, by determining the PUSCH multiplexed by the UCI according to the service type or priority, more reasonable transmission can be performed when the PUCCH overlaps with multiple PUSCHs. For example, the transmission of information with higher priority can be guaranteed as much as possible, or the transmission of services with higher reliability and delay requirements can be guaranteed as much as possible, or the transmission of UCI can be guaranteed as much as possible, so that the network device can obtain the transmission information in time. Feedback.

In this application, the resource occupied by the UCI on the target channel can be determined by the offset value beta-offset. The beta-offset can be notified to the terminal device by scheduling the DCI of the PUCSH, and can also be configured to the terminal device by high-level parameters.

Hereinafter, the two manners of determining the PUSCH according to the priority and determining the target PUSCH according to the service type will be described respectively.

Method 1: Determine the target PUSCH according to the priority

In this manner, the target PUSCH may be a PUSCH that satisfies the following conditions among the M PUSCHs:

Condition 1: The priority is not higher than the UCI.

Condition 2: The first condition is satisfied.

That is, the target PUSCH may be a PUSCH whose priority is not higher than the UCI and satisfies the first condition among the M PUSCHs. The meaning of the first condition is as described above.

Exemplarily, referring to FIG. 16 , the M PUSCHs are PUSCH#1 and PUSCH#2, if the priorities of PUSCH#1 and PUSCH#2 are not higher than the UCI, and both PUSCH#1 and PUSCH#2 satisfy the first condition, the target PUSCH may be PUSCH #1 or PUSCH #2.

Referring to FIG. 17 , the M PUSCHs are PUSCH#1 to PUSCH#3.

Method 2: Determine the target PUSCH according to the service type

In this way, according to the different business types of UCI, it will be explained in different situations.

Case 1: The service type of the UCI is URLLC.

Further, the PUSCH for sending the UCI may be the earliest PUSCH among all the PUSCHs that satisfy the first condition.

Exemplarily, referring to FIG. 18 , the M PUSCHs are PUSCH#1 and PUSCH#2, and the service type of UCI is URLLC. If both PUSCH#1 and PUSCH#2 satisfy the first condition, the target PUSCH may be PUSCH#1 or PUSCH#2, or the target PUSCH may be the earliest PUSCH among PUSCH#1 and PUSCH#2, namely PUSCH# 1. In FIG. 18, the service type of PUSCH#1 may be URLLC or eMBB; the service type of PUSCH#2 may be URLLC or eMBB.

Referring to FIG. 19 , the M PUSCHs are PUSCH#1 to PUSCH#3, and the service type of UCI is URLLC. If neither PUSCH#1 nor PUSCH#2 meets the first condition, and PUSCH#3 satisfies the first condition, the target PUSCH may be PUSCH#3. In Figure 19, the service type of PUSCH#1 can be URLLC or eMBB; the service type of PUSCH#2 can be URLLC or eMBB; the service type of PUSCH#3 can be URLLC or eMBB.

Case 2: The service type of the UCI is eMBB.

Further, the target PUSCH may be the earliest PUSCH that satisfies the first condition among the PUSCHs whose service type is eMBB among the M PUSCHs.

Exemplarily, referring to FIG. 20 , the M PUSCHs are PUSCH#1 and PUSCH#2, and the service type of UCI is eMBB. Both PUSCH#1 and PUSCH#2 satisfy the first condition, the service type of PUSCH#1 is eMBB, and the service type of PUSCH#2 is URLLC, so the target PUSCH may be PUSCH#1.

Referring to FIG. 21 , the M PUSCHs are PUSCH#1 to PUSCH#3, and the service type of UCI is eMBB. PUSCH#1 to PUSCH#3 all meet the first condition, the service type of PUSCH#1 is URLLC, and the service type of PUSCH#2 and PUSCH#3 is eMBB, then the target PUSCH can be PUSCH#2 or PUSCH#3 , or the target PUSCH may be the earliest PUSCH among the PUSCH#2 and PUSCH#3, that is, PUSCH#2.

In a possible implementation manner, if none of the M PUSCHs satisfy the first condition, or none of the service types are eMBB, the UCI is discarded and the PUCCH is not sent.

For example, if in FIG. 20, neither PUSCH#1 nor PUSCH#2 satisfy the first condition, the PUCCH carrying the UCI is discarded, and PUSCH#1 and PUSCH#2 are sent.

For another example, referring to FIG. 22 , the M PUSCHs are PUSCH#1 and PUSCH#2, and the service type of UCI is eMBB. If the service types of PUSCH#1 and PUSCH#2 are both URLLC, the PUCCH carrying the UCI is discarded, and PUSCH#1 and PUSCH#2 are sent.

The method of claim 8, wherein the priority of the uplink data channel is indicated by scheduling downlink control information of the uplink data channel, or wherein the priority of the uplink data channel is indicated by a Radio Network Temporary Identity (RNTI) scrambling the downlink control information of the uplink data channel; and/or the presence of a gas in the gas,

the priority of the uplink control information is the priority of a downlink data channel corresponding to the uplink control information, and the priority of the downlink data channel is indicated by scheduling the downlink control information of the downlink data channel, or the priority of the downlink data channel is indicated by a Radio Network Temporary Identifier (RNTI) of the downlink control information of the downlink data channel which is scheduled by scrambling.

10. A method for transmitting uplink information, comprising:

determining a first time-frequency resource, wherein the first time-frequency resource is used for sending an uplink control channel, and the uplink control channel is used for carrying uplink control information;

determining a second time-frequency resource, wherein the second time-frequency resource is used for sending N uplink data channels, the N uplink data channels bear the same transmission blocks, and N is an integer greater than 1;

and under the condition that the first time-frequency resource and the second time-frequency resource are overlapped on a time domain, if an uplink data channel meeting a first condition exists in the N uplink data channels, receiving the uplink control information on a first target channel, wherein the first target channel is one of the N uplink data channels meeting the first condition, and the first condition is a time line condition that the uplink control information is multiplexed on the uplink data channel for transmission.

11. The method of claim 10, wherein there are also uplink data channels of the N uplink data channels that do not satisfy the first condition.

12. The method according to claim 10 or 11, wherein the first target channel is an earliest uplink data channel among all uplink data channels satisfying the first condition among the N uplink data channels.

13. The method of claim 10 or 11, wherein the first target channel and the uplink control channel overlap in a time domain.

14. The method of claim 13, wherein the first target channel is an earliest uplink data channel among all uplink data channels of the N uplink data channels that overlap in time domain with the uplink control channel, which satisfies the first condition.

15. The method of any of claims 10 to 14, further comprising:

receiving the uplink control information on at least one second target channel of the N uplink data channels, wherein the second target channel is later than the first target channel.

16. The method of claim 15, the second target channel overlaps with the uplink control channel in a time domain.

17. The method of any of claims 10 to 16, wherein the receiving the uplink control information on the first target channel comprises:

receiving the uplink control information on the first target channel if the priority of the uplink control channel is lower than or equal to the priority of the uplink data channel.

18. The method of claim 17, wherein the priority of the uplink data channel is indicated by scheduling downlink control information of the uplink data channel, or wherein the priority of the uplink data channel is indicated by a Radio Network Temporary Identity (RNTI) scrambling the downlink control information of the uplink data channel; and/or the presence of a gas in the gas,

the priority of the uplink control information is the priority of a downlink data channel corresponding to the uplink control information, and the priority of the downlink data channel is indicated by scheduling the downlink control information of the downlink data channel, or the priority of the downlink data channel is indicated by a Radio Network Temporary Identifier (RNTI) of the downlink control information of the downlink data channel which is scheduled by scrambling.

19. A communications apparatus, comprising means for performing the method of any of claims 1-9 or 10-18.

20. A communications device comprising a processor and interface circuitry for receiving and transmitting signals from or sending signals to other communications devices than the communications device, the processor being arranged to implement the method of any one of claims 1 to 9 or 10 to 18 by means of logic circuitry or executing code instructions.

21. A computer-readable storage medium, in which a program or instructions are stored which, when executed, implement the method of any one of claims 1 to 9 or 10 to 18.
