The technical solutions provided by the present application will be described in detail below with reference to the accompanying drawings.

To facilitate understanding of the embodiments of the present application, several concepts involved in the present application are briefly introduced below.

1. Time slot and time domain symbols

A time slot can be understood as a part of serial self-multiplexing of time slot information dedicated to a single channel. A time slot can be understood as a channel.

In this embodiment of the present application, a symbol is also called a time-domain symbol, which may be an orthogonal frequency division multiplexing (OFDM) symbol, or a single carrier frequency division multiple access (SC) symbol. -FDMA) symbol, wherein SC-FDMA is also called orthogonal frequency division multiplexing with transform precoding (orthogonal frequency division multiplexing with transform precoding, OFDM with TP).

In addition, a time domain symbol can also be understood as a time unit, for example, a time unit can be one or more subframes; or, it can also be one or more time slots; or, it can also be one or more symbols. When one time unit is one symbol, in the description of the embodiments of the present application, the time domain symbol and the time unit may be equivalent.

2. Physical uplink channel

A channel that can be used to carry uplink control information and/or uplink data. For example, the physical uplink channel may include a physical uplink control channel (physical uplink control channel, PUCCH) defined in the LTE protocol or the NR protocol, a physical uplink shared channel (physical uplink share channel, PUSCH) and defined as the network evolves. Additional upstream channels for the above functions.

3. Downlink control information (download control information, DCI)

Mainly used to send downlink scheduling allocation information, there are many different formats, including but not limited to DCI format0-0, 0-1, 1-0, 1-1, 2-0, 2-1, 2-2, 2 -3.

4. PUCCH resource indicator field or PUCCH resource indicator field (PUCCH resource indicator field)

The M bit (bit) information field in the DCI is used to indicate available transmission resources for the HARQ-ACK information. Optionally, the M is equal to 3.

The following describes in detail the uplink control information (uplink control information, UCI) of the transmission object in the embodiment of the present application.

In this embodiment of the present application, the uplink control information UCI includes at least one of a hybrid automatic repeat request acknowledgement (HARQ-ACK), a scheduling request (SR), and a CSI (CQI, PMI, RI). one.

As an example and not a limitation, the uplink control information in this embodiment of the present application may include, but is not limited to, one or more of the following information:

1. Feedback information

In this embodiment of the present application, the uplink control information may include feedback information for downlink data.

Specifically, in this embodiment of the present application, a feedback technology may be used for transmission of downlink data, which is an example and not a limitation, and the feedback technology may include, for example, a hybrid automatic repeat request (HARQ) technology.

Among them, the HARQ technology is a technology formed by combining forward error correction coding (forward error correction, FEC) and automatic repeat request (automatic repeat request, ARQ).

For example, in the HARQ technology, after receiving the data from the transmitting end, the receiving end can determine whether the data is accurately decoded. If the decoding cannot be accurately performed, the receiving end can feed back non-acknowledgement (NACK) information to the transmitting end, so that the transmitting end can determine, based on the NACK information, that the receiving end has not received the data accurately, so that retransmission processing can be performed; If the decoding can be performed accurately, the receiving end can feed back acknowledgement (ACK) information to the transmitting end, so that the transmitting end can determine, based on the ACK information, that the receiving end has received the data accurately, and thus can determine that the data transmission is completed.

That is, in this embodiment of the present application, when the receiving end successfully decodes, it can send ACK information to the sending end, and when the decoding fails, it can feed back NACK information to the sending end.

As an example and not a limitation, in this embodiment of the present application, the uplink control information may include ACK information or NACK information in the HARQ technology. Among them, the HARQ-ACK is used to feed back the reception status of the downlink data channel PDSCH, and when the UE receives it correctly, an ACK will be sent. When the UE receives an error, it will send a NACK. The base station determines the next scheduling strategy, such as retransmission or new transmission, according to the feedback information of the UE on the PDSCH channel.

It should be understood that the contents of the feedback information listed above are only exemplary descriptions, and the present application is not limited to this, and other information that can indicate the reception of the downlink data by the terminal equipment all fall within the protection scope of the present application, such as , the feedback information may further include discontinuous transmission (discontinuous transmission, DTX) information, where the DTX information may be used to indicate that the terminal device has not received downlink data.

2. Channel State Information CSI

In the field of wireless communication, the so-called CSI is the channel attribute of the communication link. CSI is the channel state information fed back to the base station after the UE measures the channel state. The information further includes CQI/PMI/RI and other information. It describes the fading situation of the signal on each transmission path, that is, the value of each element in the channel gain matrix H, such as signal scattering (scattering), environmental fading (multipath fading or shadowing fading), distance fading (powerdecay of distance) and other information. CSI can make the communication system adapt to the current channel conditions, and provide a guarantee for high-reliability and high-rate communication in a multi-antenna system.

3. Channel quality indicator (CQI) information

In this embodiment of the present application, the CQI may be used to reflect the channel quality of a physical downlink shared channel (physical downlink shared channel, PDSCH). CQI is channel quality indication information, which is used to directly feed back the channel quality. The base station may further determine a modulation coding strategy (modulation coding strategy, MCS) adopted for sending data according to the CQI. When the value of the feedback CQI is high, a higher coding and modulation mode and a higher code rate can be used to carry more information on the limited resources, thereby increasing the data transmission rate. When the value of the feedback CQI is low, a lower coding modulation mode and a lower code rate can be used, and more time-frequency resources can be used to transmit data, thereby improving the reliability of data transmission. At the same time, by measuring the CQIs of different frequency domain resources, the UE enables the base station to schedule data on the frequency domain resources with good channel quality, thereby obtaining the frequency domain scheduling gain.

As an example but not a limitation, in this embodiment of the present application, 0 to 15 may be used to represent the channel quality of the PDSCH. 0 means the worst channel quality, 15 means the best channel quality.

In this embodiment of the present application, the terminal device may send the CQI information to the network device on the PUCCH or a physical uplink shared channel (physical uplink shared channel, PUSCH). The network device can determine the wireless channel conditions of the current PDSCH or PUSCH according to the CQI information, and then complete the scheduling for the PDSCH. For example, in the embodiment of the present application, the network device can determine the adaptive modulation and modulation (adaptive modulation and coding, AMC) based on the CQI information. ), modulation and coding scheme (MCS), code rate or data amount of uplink transmission or downlink transmission, etc.

4. Rank indication (RI) information

In this embodiment of the present application, RI is rank indication information, which is used to feed back to the base station the number of layers that can be separated from the channel. The more layers, the greater the amount of data that can be transmitted simultaneously. The RI information may be used to indicate the number of valid data layers of the PDSCH, or in other words, the RI information may be used to indicate the number of code words (code word, CW) that the terminal device currently supports.

5. Precoding matrix indicator (PMI) information

In this embodiment of the present application, the PMI information may be used to indicate an index (index) of the codebook set, and the PMI is a precoding matrix identifier for sending data that the UE feeds back to the base station according to the measured channel quality. The base station may determine the corresponding precoding matrix according to the fed back PMI information. That is, in the case of using a multi-antenna technique, for example, a multiple-input multiple-output (MIMO) technique, in the baseband processing, precoding processing (precoding) based on a precoding matrix is performed. The terminal device can indicate the precoding matrix through the PMI information, so that the signal quality of the PDSCH can be improved.

In addition, there is some information such as CSI-RS resource indicator (CSI-RS resource indicator, CRI), which is used to feed back to the base station which measurement resource measures the best channel quality among multiple measurement resources.

It should be understood that the specific contents of the CSI listed above are only exemplary descriptions, and should not constitute any limitation to the present application. The CSI sent by the receiving end device to the transmitting end device may include one or more of the above enumeration, or may also include other information used to characterize CSI except the above enumeration, which is not limited in this application.

In this embodiment of the present application, sending uplink control information may refer to sending data or information carried on the uplink control channel PUCCH or the uplink shared channel PUSCH, where the data or information may refer to channel-coded data or information. This application does not limit this.

Similarly, in this embodiment of the present application, sending downlink control information may refer to sending data or information carried on the downlink control channel PDCCH or the downlink shared channel PDSCH, where the data or information may refer to channel-coded data or information. This application does not limit this.

Hereinafter, without loss of generality, the embodiments of the present application are described in detail by taking an interaction process between a terminal device and a base station as an example. The terminal device may be any terminal device in a wireless communication system that has a wireless connection relationship with one or more network devices. It can be understood that any terminal device in the wireless communication system can implement wireless communication based on the same technical solution. This application does not limit this.

In the 5G system, the format of PUCCH and the corresponding rules are shown in Table 1 below. It can be seen from Table 1 below that the resources of PUCCH format 2, format 3 and format 4 can support mixed transmission of HARQ, CSI and SR. In this application, a PUCCH resource whose number of symbols included in the PUCCH is less than or equal to a preset constant N ₁ is referred to as a short-format PUCCH, and a PUCCH resource whose number of symbols included is greater than or equal to a preset constant N ₂ is referred to as a PUCCH resource in the short format. It is a short-format PUCCH, which is called a long-format PUCCH. Wherein, N ₁ and N ₂ are positive integers, and the values of N ₁ and N ₂ may be the same or different.

It should be understood that the preset constants N ₁ and N ₂ may be constants configured by high-layer signaling, or constants configured by physical layer signaling. In the embodiments of the present application, the high-layer signaling may be radio resource control (radio resource control, RRC) signaling, and may also be MAC layer signaling; the physical layer signaling may be DCI. The present application does not limit the configuration manner of the preset constants.

For example, in 5G, the value of N ₁ can be 2. The PUCCH in the short format may refer to the PUCCH including 1 or 2 symbols, such as PUCCH format 2 and PUCCH format 0; the value of N ₂ may be 4, and the PUCCH in the long format may refer to the number of symbols included is 4 to 14 PUCCHs, such as PUCCH format 1, format 3, and format 4. In this embodiment of the present application, the PUCCH in the short format may be PUCCH format 2, and the PUCCH in the long format may be PUCCH format 1, format 3, and format 4.

Table 1

Specifically, the resources for transmitting HARQ-ACK are dynamically indicated by the base station. First, the base station configures one or more resource sets (resource sets) for the terminal device, and the range of the number of UCI information bits carried by different resource sets is different. The base station and the terminal device will determine a resource set from one or more resource sets according to the total number of bits of HARQ-ACK information that the terminal device needs to feed back, and then according to the relevant HARQ in the DCI signaling sent by the base station. - The resource indicator field (resource indicator field) of ACK information feedback determines that one resource in the resource set carries HARQ-ACK information.

FIG. 2 is a schematic diagram of an example of a resource selection process in an uplink transmission process provided by an embodiment of the present application. Specifically, in one time unit, the PUCCH resource determined by the base station to carry HARQ-ACK may be a short format with the number of OFDM symbols less than or equal to two symbols, such as PUCCH format 2, which is used to carry the CSI report# The PUCCH of 1 may be in a short format, such as PUCCH format 2. In this time unit, the above-mentioned PUCCH resources carrying HARQ-ACK information and PUCCH resources carrying CSI information may have an overlapping area in the time domain. It should be understood that the overlap here may be partial overlap or full overlap. It should also be understood that a time unit here may be a time slot (slot) or a time window.

As shown in FIG. 2 , PUCCH format 2 carrying HARQ-ACK information and PUCCH format 2 carrying CSI report #1 have a partial overlap region in the time domain. In this case, the base station can re-select a resource set according to the HARQ-ACK information required to be fed back and reported by the terminal device and the total number of information bits reported by the CSI, among the above resource sets, according to the range of the number of information bits, And a new PUCCH is determined from the resource set reselected by the resource indication field in the DCI signaling.

Or, as shown in FIG. 3, another example of the resource selection schematic diagram of the uplink transmission process, when the PUCCH resource carrying HARQ-ACK information and the PUCCH carrying CSI information and the PUCCH carrying SR information have overlapping areas in the time domain, the base station can According to the total number of information bits of HARQ-ACK information, CSI report and SR information to be fed back and reported, in the above resource set, according to the range of the number of information bits, a resource set is re-selected, and according to the above DCI signaling The Resource Indication field in the re-selected new set of resources identifies a new PUCCH.

It should be understood that the above-mentioned base station re-selects a resource set, which is referred to as a "first resource set" in this embodiment of the present application, and the first resource set may be the original resource set or another newly selected resource set, as long as It is ensured that the total number of information bits of the HARQ-ACK information and the CSI report, or the total number of information bits of the HARQ-ACK information and the CSI report and the SR information is within the range of the number of bits of the first resource set.

For the above several possible situations, the new PUCCH re-determined by the base station and the terminal equipment may be a PUCCH long format with OFDM symbols from 4 to 14, such as PUCCH format 1, PUCCH format 3 and PUCCH format 4 listed above. However, if there is another PUCCH resource with the number of symbols from 4 to 14 in the above-mentioned time slot, and the PUCCH is used with the newly determined to carry HARQ-ACK and CSI information, or to carry HARQ-ACK, CSI and SR The PUCCH resources do not overlap in the time domain. According to the stipulations in the protocol, two long-format PUCCHs with a number of 4 to 14 symbols cannot be sent in one time slot. When two long-format PUCCHs of 4 to 14 symbols exist simultaneously in a time slot, the terminal equipment and the base station cannot perform deterministic transmission, in other words, the behavior of the base station and the terminal equipment is uncertain. Therefore, there is a need for a method for determining resources that can be used when the resources of the PUCCH carrying HARQ-ACK and CSI information overlap in the time domain, or the resources of the PUCCH carrying the information of HARQ-ACK, CSI and SR overlap in the time domain , and re-determine a PUCCH resource, while avoiding the occurrence of two PUCCHs with a number of 4 to 14 symbols in a time slot, thereby avoiding the uncertainty of transmission between the base station and the terminal device.

FIG. 4 is a schematic flowchart of an example of a method 400 for determining transmission resources provided by an embodiment of the present application. The method 400 may be applied to the terminal device 102 or the terminal device 103 of the above-mentioned wireless communication system 100 . FIG. 5 is a schematic diagram of interaction between a terminal device and a base station in an embodiment of the present application, which will be described in detail below with reference to FIG. 4 and FIG. 5 .

As shown in Figure 5, the method 500 includes the following.

S501, in the first time slot, when the first uplink resource and the second uplink resource overlap in the time domain, according to a preset rule, the number of OFDM symbols included in the first resource set is less than or equal to 2 The first resource is determined from the uplink resources of .

It should be understood that the first uplink resource is used to carry the first uplink information, the second uplink resource is used to carry the second uplink information, and the first uplink information and the second uplink information are hybrid automatic repeat request response messages HARQ-ACK and any one of channel state information CSI, and any resource in the first resource set is a resource configured for an uplink control channel.

For example, the first uplink resource is the uplink control channel format PUCCH format 2, and the second uplink resource may also be the uplink control channel format PUCCH format 2.

Optionally, the types of the first uplink information and the second uplink information may be the same or different.

Specifically, the first uplink information may be HARQ-ACK, and the second uplink information may be CSI, then the situation that the first uplink resource and the second uplink resource overlap in the time domain may be the uplink for carrying HARQ-ACK The resources and uplink resources used to carry CSI completely overlap or partially overlap in the time domain.

Alternatively, both the first uplink information and the second uplink information may be HARQ-ACK, then the situation that the first uplink resource and the second uplink resource overlap in the time domain may be uplink resources used to carry two HARQ-ACKs All or part of the overlap in the time domain.

Alternatively, both the first uplink information and the second uplink information may be CSI, then the overlapping of the first uplink resource and the second uplink resource in the time domain refers to the fact that the uplink resources used to carry the two types of CSI are in the time domain. All or part of the above.

Alternatively, another possible situation is also included here, that is, the uplink resources for carrying HARQ-ACK, the uplink resources for carrying CSI and the uplink resources for carrying SR all overlap or partially overlap in the time domain. It should be understood that in the case where the multiple uplink resources listed above all overlap or partially overlap in the time domain, the technical solutions provided in this application can be used to determine the transmission resources between the base station and the terminal device. In other words, there may be more This scenario will cause the base station and the terminal device to determine uplink transmission resources. As long as the technical solutions provided in the embodiments of the present application are used to determine the transmission resources between the base station and the terminal device, it falls within the protection scope of the present application.

It should also be understood that the "first resource set" in S501 may be an uplink resource set configured by the base station for the terminal device, for example, through high-layer signaling. Specifically, after the terminal device establishes a communication connection with the base station, it will request resources from the base station, and the base station configures multiple uplink resource sets for the terminal device, and each uplink resource set includes multiple PUCCH resources with different numbers of symbols, such as those listed above. long-format PUCCH resources with different numbers of symbols, such as PUCCH format 1, PUCCH format 3, and PUCCH format 4; or multiple short-format PUCCH resources with different numbers of symbols, such as PUCCH format 2.

Optionally, the first resource set is configured for at least one of the first uplink information and the second uplink information.

Specifically, for the base station, the first resource set may be determined according to at least one of the first uplink information and the second uplink information.

Correspondingly, the terminal device may determine the first resource set according to at least one of the first uplink information and the second uplink information. For example, the first resource set is a resource set determined according to the first uplink information; or the first resource set is a resource set determined according to the second uplink information; or the first resource set is determined according to the first uplink information and the resource set determined by the second uplink information.

Specifically, among the multiple resource sets configured by the base station for the terminal device, the base station needs to determine the first resource set according to the range of the number of information bits. Specifically, the base station can determine the first resource set according to the HARQ-ACK information to be fed back and reported; or re-determine the first resource set according to the HARQ-ACK information and the number of information bits reported by the CSI; or according to the HARQ-ACK information, CSI The report and the total number of information bits of the SR information determine the first resource set.

Correspondingly, the terminal device receives first indication information and second indication information from the base station, where the first indication information is used to indicate the first uplink resource, and the second indication information is used to indicate the second uplink resource, and the first uplink resource is the same as the The second uplink resource overlaps in the time domain, the first uplink resource corresponds to the first uplink information, the second uplink resource corresponds to the second uplink information, and the first uplink information and the second uplink information are hybrid automatic repeater Send any one of the request-response message HARQ-ACK and the channel state information CSI.

It should be understood that the first indication information may include one or more pieces of indication information, and the second indication information may include one or more pieces of indication information. In the embodiments of this application, it is often mentioned that the first uplink resource corresponds to the first uplink information, and "corresponding to" here can be understood as "bearer", that is, the first uplink resource carries the first uplink information.

FIG. 6 is a schematic diagram of an example of a resource selection process provided by an embodiment of the present application. The process of determining a PUCCH by a base station and a terminal device is described in detail below with reference to FIG. 6 . It is assumed that in one time slot, there are three resources, namely, a PUCCH carrying CSI report #1, a PUCCH carrying CSI report #2, and a PUCCH carrying HARQ-ACK information.

(1) The base station configures multiple uplink resource sets for the terminal equipment, such as resource set 1 and resource set 2 in FIG. 6 , each uplink resource set includes multiple PUCCHs of different formats, and resource set 1 in the figure includes resource 1 , Resource 3, Resource 5, Resource 8, etc. Each resource has a different format. Assume that at this time, the base station determines resource set 1 according to the number of bits of HARQ-ACK information to be transmitted, and informs the terminal device through DCI. The terminal device determines resource set 1 according to the PUCCH resource indication field in the DCI. Resource 3.

(2) When the resources of HARQ-ACK and CSI report #1 overlap in time domain, or the resources of HARQ-ACK and CSI report #1 overlap in time domain, and the PUCCH carrying CSI report #2 When it is a long-format PUCCH, the base station needs to reselect resource set 2 according to the HARQ-ACK information and the total number of bits of the CSI report. It should be understood that resource set 2 here is the first resource set defined in this application.

(3) In order to avoid the simultaneous occurrence of two long-format PUCCHs in one time slot, the terminal device should select a short-format resource in resource set 2, such as resource 1 in FIG. 6 , resource 1 may be PUCCH format 2.

(4) After the first resource set is determined, the base station and the terminal device determine the first resource from uplink resources whose number of OFDM symbols included in the first resource set is less than or equal to 2 according to preset rules. For example, the base station and the terminal device may determine one PUCCH among multiple short format PUCCHs with different numbers of symbols, and as the first resource, the short format PUCCH may be PUCCH format 2.

It should be understood that, in this embodiment of the present application, the number of time domain symbols occupied by the first resource is less than or equal to 2; and/or, the resource format of the first resource is the first format. The first format may be PUCCH format2.

For ease of description, a resource whose number of occupied time-domain symbols included in the first resource set is less than or equal to 2 is referred to as a second resource, and the first resource set includes at least one second resource. In the following description, both the second resource and the uplink resource with the number of symbols less than or equal to 2 refer to the short format resource defined in this application, for example, PUCCH format 2.

The following introduces several methods for how to select the first resource from multiple short-format PUCCHs.

method one

The base station and the terminal device may determine the first resource according to the number of symbols of each uplink resource in the uplink resources whose number of symbols is less than or equal to 2.

For example, the uplink resource with the largest number of symbols among the uplink resources whose number of symbols is less than or equal to 2 is determined as the first resource. For example, for PUCCH format 2, it is possible that the first PUCCH includes 1 symbol and the second PUCCH includes 2 symbols, then the PUCCH with the largest number of symbols is selected as the first resource, that is, the PUCCH including 2 symbols is selected.

When the first resource set includes a plurality of uplink resources with the largest number of symbols and the number of symbols is less than or equal to 2, determine the resource with the earliest or latest start symbol among the uplink resources with the largest number of symbols as the resource with the earliest start symbol the first resource; or the resource with the least number of resource blocks RB among the uplink resources with the largest number of symbols is determined as the first resource.

It should be understood that each uplink resource will occupy a certain time domain position and frequency domain position. In the time domain, the number of symbols included in the PUCCH is different. For example, the PUCCH in the short format may include 1 or 2 symbols; in the frequency domain, the number of RBs included in the PUCCH is different. For example, the PUCCH format 2 may include 1 to 16 RBs. The above situation considers the case where the time domain and frequency domain space occupied by the PUCCH is the smallest, and selecting the resource with the smallest number of RBs can save transmission resources.

For example, when the second PUCCH includes 2 symbols and the third PUCCH also includes 2 symbols, the selection is made according to the earliest or latest starting symbol of the PUCCH. Preferably, selecting the PUCCH with the latest start symbol can ensure that the terminal device has sufficient time for receiving the message from the base station, and then feeds back the HARQ-ACK.

Optionally, when the first resource set includes multiple uplink resources with the same starting symbol and the number of symbols is less than or equal to 2, or the first resource set includes multiple uplink resources with the smallest number of RBs, the number of symbols is less than or equal to When the number of uplink resources is 2, the resource with the smallest resource index among the plurality of uplink resources whose number of symbols is less than or equal to 2 is determined as the first resource.

Method Two

The base station and the terminal device may determine the uplink resource whose number of symbols is less than or equal to 2 and which is the same as the time domain length of the first uplink resource or the second uplink resource as the first resource.

When the first resource set includes a plurality of uplink resources with the same time domain length as the first uplink resource or the second uplink resource and the number of symbols is less than or equal to 2, the plurality of uplink resources and the first uplink resource Or the resource with the earliest or latest start symbol among the uplink resources with the same time domain length of the second uplink resource and the number of symbols less than or equal to 2 is determined as the first resource; or the multiple and the first uplink resource Or the resource with the least number of RBs occupied in the uplink resources with the same time domain length of the second uplink resource and the number of symbols less than or equal to 2 is determined as the first resource.

For example, when the first uplink resource is used to carry HARQ-ACK, and the second uplink resource is used to carry information CSI, it can be selected from short format resources of the same length as the resource carrying HARQ-ACK. When there are still multiple short-format resources in the first resource set in such a selection method, selection is made according to the start symbols of these short-format resources, for example, the earliest or latest start symbol, here the resource with the latest start symbol In order to optimize the resources, it can be ensured that the terminal device has sufficient receiving time when receiving the message from the base station.

Optionally, when the first resource set includes multiple uplink resources with the same starting symbol and the number of symbols is less than or equal to 2, or the first resource set includes multiple uplink resources with the smallest number of RBs, the number of symbols is less than or equal to When the number of uplink resources is 2, the resource with the smallest resource index among the plurality of uplink resources whose number of symbols is less than or equal to 2 is determined as the first resource.

Method three

The base station and the terminal device may determine the uplink resource of which the number of symbols with the lowest coding rate is less than or equal to 2 in the first resource set is the first resource.

When the first resource set includes a plurality of uplink resources whose number of symbols with the lowest coding rate is less than or equal to 2, the method further includes:

Determine the uplink resource with the earliest or latest start symbol of the plurality of resources with the lowest coding rate that is less than or equal to 2 as the first resource; and/or

The uplink resource with the least number of resource blocks and RBs occupied by the plurality of resources with the lowest coding rate and the number of symbols less than or equal to 2 is determined as the first resource.

Optionally, when the first resource set includes multiple uplink resources with the same starting symbol and the number of symbols is less than or equal to 2, or the first resource set includes multiple uplink resources with the smallest number of RBs, the number of symbols is less than or equal to When the number of uplink resources is 2, the resource with the smallest resource index among the plurality of uplink resources whose number of symbols is less than or equal to 2 is determined as the first resource.

Method 4

The base station and the terminal device may determine the resource with the earliest or latest start symbol among the multiple uplink resources with the largest number of symbols as the first resource; and/or the resource occupied by the multiple uplink resources with the largest number of symbols The resource with the least number of RBs in the resource block is determined as the first resource.

When the first resource set includes multiple uplink resources with the same starting symbol and the number of symbols is less than or equal to 2, or the first resource set includes multiple uplink resources with the smallest number of RBs and the number of symbols is less than or equal to 2 , the resource with the smallest resource index among the plurality of uplink resources whose number of symbols is less than or equal to 2 is determined as the first resource.

Method five

The base station and the terminal device may determine the resource with the smallest resource index among the plurality of uplink resources whose number of symbols is less than or equal to 2 as the first resource.

It should be understood that the various rules for selecting uplink resources listed above may be specified by protocols, or may be configured for the base station and terminal equipment through high-level signaling, or the base station may notify the terminal equipment through physical layer signaling. In the embodiment of the present application, the high-layer signaling may be radio resource control (radio resource control, RRC) signaling, or may be MAC layer signaling.

Through the above-mentioned methods for selecting the first resource from a plurality of PUCCH resources whose number of included symbols is less than or equal to 2, and/or whose resource format is the first format, the PUCCH resources bearing HARQ-ACK can be compared with the PUCCH resources bearing CSI. When the PUCCH resources of the device overlap in the time domain, or the PUCCH resources that carry HARQ-ACK, the PUCCH resources that carry CSI, and the PUCCH resources that carry SR overlap in the time domain, a method for determining resources is provided for the terminal device and the base station, which improves the transmission reliability. At the same time, it is avoided that the terminal equipment selects a PUCCH whose number of symbols is greater than or equal to 4 in the process of reselection of uplink resources, when there is another occupied time domain symbol whose number is greater than or equal to 4 in the same time slot, and/or the resource format When the PUCCH is in the second format, two PUCCH resources with the number of symbols greater than or equal to 4 appear in one time slot, causing uncertainty in uplink transmission between the terminal device and the base station.

It should be understood that in this application, the PUCCH in the first format is also referred to as the PUCCH in the short format, and the PUCCH in the short format may refer to a PUCCH including one or two symbols, such as PUCCH format 2 and PUCCH format 0; the second format The PUCCH is also called a long-format PUCCH, and the long-format PUCCH may refer to a PUCCH including 4 to 14 symbols, such as PUCCH format 1, format 3, and format 4.

S502: Transmit the first uplink information and the second uplink information through the first resource.

Specifically, the terminal device executes S420, and sends the first uplink information and the second uplink information through the first resource. Correspondingly, the base station receives the first uplink information and the second uplink information through the first resource.

In the above, in the transmission process of HARQ-ACK and CSI, or HARQ-ACK, CSI and RS, the base station and terminal equipment can ensure the reliability of transmission through the determined uplink resources.

In addition, when a third uplink resource and a fourth uplink resource exist in the first time slot, the number of symbols included in the third uplink resource and the fourth uplink resource is greater than 4, and the third uplink resource and the fourth uplink resource When there is no overlap in the time domain, that is, it can be understood that in a time slot, when there are two long-format PUCCHs including 4 to 14 symbols that do not overlap in the time domain at the same time, according to the requirements in the protocol, in one Two long-format PUCCHs including 4 to 14 symbols cannot be sent in a time slot, so the behavior of the UE and the base station will be uncertain at this time.

FIG. 7 is a schematic interaction diagram of another example of a resource determination method provided by an embodiment of the present application. The method 700 can be applied to a terminal device or a base station of the above-mentioned wireless communication system 100 . Method 700 includes:

S701. Discard one of the third uplink resource and the fourth uplink resource according to a preset rule, where the number of symbols included in the third uplink resource and the fourth uplink resource is greater than 4.

Optionally, the third uplink resource is used to carry the third uplink information, the fourth uplink resource is used to carry the fourth uplink information, and the third uplink information and the fourth uplink information are hybrid automatic repeat request response message HARQ -ACK; or the third uplink information and the fourth uplink information are channel state information CSI; or the third uplink information and the fourth uplink information are at least two of HARQ-ACK, channel state information CSI and scheduling request SR information.

Specifically, for example, in FIG. 2 , it is assumed that there are three resources in a time slot, namely the PUCCH carrying CSI report #1, the PUCCH carrying CSI report #2, and a PUCCH carrying HARQ-ACK information, and carrying CSI The PUCCH of report #2 is a long-format resource, such as PUCCH format 4; or in Figure 3, there are four resources, namely PUCCH carrying CSI report #1, PUCCH carrying CSI report #2, and PUCCH carrying SR A PUCCH carrying HARQ-ACK information and a PUCCH carrying CSI report #2 is a long-format resource, such as PUCCH format 4. If the new transmission resource determined by the terminal device according to the total number of bits of HARQ-ACK and CSI, or according to the total number of bits of HARQ-ACK, CSI and SR is a long-format PUCCH, such as PUCCH format 1, PUCCH format 3 or PUCCH Any one of the formats 4, and the newly determined long format PUCCH and the PUCCH used to carry the CSI report #2 do not overlap in the time domain, then there are two long format PUCCHs in this one slot.

In order to ensure the reliability of transmission, the terminal device may discard one of the long-format PUCCHs according to certain rules, and only keep one long-format PUCCH in this time slot.

In a possible implementation manner, the terminal device may discard the uplink resources carrying the uplink information of the first priority according to the preset priority order, and reserve the uplink resources carrying the uplink information of the second priority, wherein the second priority higher than the first priority.

For example, if the priority of HARQ-ACK is higher than the priority of CSI, the uplink resources used for carrying CSI may be discarded.

Alternatively, if the priority of the HARQ-ACK is lower than the priority of the CSI, the uplink resources used to carry the HARQ-ACK may be discarded.

Alternatively, if the priority of the information of the CSI report #2 is higher than the priority of the CSI report #1, the long-format PUCCH used to carry the HARQ-ACK and the CSI report #1 is discarded.

Or, if the priority of the information of the CSI report #2 is lower than the priority of the HARQ-ACK and the CSI report #1, the long-format PUCCH for carrying the CSI report #2 is discarded.

When the resource carrying the low-priority uplink information is discarded according to the priority of the uplink information, there is only one long-format PUCCH in the one time slot.

S702: Transmit the third uplink resource and another resource that is not discarded in the fourth uplink resource.

The terminal device sends the high-priority uplink information on the PUCCH that is not discarded, and accordingly, the base station receives the PUCCH and obtains the high-priority uplink information.

The above technical solution can avoid the problem of transmission uncertainty caused by the occurrence of two long-format PUCCH resources in one time slot during the uplink transmission process between the terminal device and the base station.

FIG. 8 is a schematic diagram of another example of a resource selection process provided by an embodiment of the present application. In the transmission process of uplink information, in the transmission process of uplink information, the resources of PUCCH carrying HARQ-ACK and CSI information overlap in the time domain in the same time slot, or the resources of PUCCH carrying HARQ-ACK, CSI and SR information are overlapped in the time domain. The resources overlap in the time domain, and the new transmission resource determined according to the total number of bits of HARQ-ACK and CSI information, or according to the total number of bits of information of HARQ-ACK, CSI and SR is the long-format PUCCH. Moreover, there is another long-format PUCCH in this time slot, and the process of resource selection as shown in FIG. 8 can be performed.

Specifically, in a time slot, PUCCH format 2 carrying HARQ-ACK and PUCCH format 2 of CSI report #1 information overlap in the time domain, and a new one is determined according to the total number of bits of HARQ-ACK and CSI report #1 information. The new PUCCH resource is the PUCCH of format 3. If the PUCCH of format 3 and the PUCCH of format 4 used to carry CSI report #2 do not overlap in the time domain, then according to the priority order of the carried uplink information, Two long-form resources are discarded. In Fig. 8, the priority of CSI report #1 is higher than that of CSI report #2, therefore, the PUCCH used to carry format 4 of CSI report #2 is discarded, thereby ensuring that there is only one long format in the slot PUCCH to improve transmission reliability.
