Before introducing the technical solutions of the present application, the related technologies of the present application are introduced below:

NR Rel-15 stipulates that when multiple overlapping physical uplink control channels (Physical Uplink Control Channel, PUCCH), or multiple PUCCHs and physical uplink shared channels (Physical Uplink Shared Channel, PUSCH) need to satisfy the multiplexing timing relationship, Only then can it be multiplexed into one channel for transmission. For the definition of the multiplexing timing relationship, please refer to TS38.213. Otherwise, the terminal device will judge this situation as an abnormal situation. The multiplexing timing relationship here is mainly to ensure that the terminal device has enough time to judge whether the information carried by different uplink channels needs to be multiplexed, and the uplink control signaling (Uplink Control Information, UCI) during multiplexing transmission. required time.

When the multiplexing sequence is satisfied, the terminal device first determines the overlapping PUCCH channel set Q, as follows:

1. Determine PUCCH A: the earliest PUCCH in the overlapping channel. If there are multiple PUCCHs with the same start, the one with the longest duration is taken. Both are the same, choose one or the other.

2. The PUCCH overlapping with PUCCH A is included in set Q.

3. The PUCCH overlapping with any PUCCH in the set Q is included in the set Q.

4. Multiplex the UCIs in all sets Q into one PUCCH, and determine the PUCCH B according to the number of UCI bits and the PUCCH resource indicator (PUCCH Resource Indicator, PRI).

The terminal device determines whether PUCCH B overlaps with other PUCCHs. If so, repeat 1 to 4. The set Q determined by the above method is shown in FIG. 2 .

After determining the set Q of overlapping PUCCH channels, the terminal device determines one PUCCH for the set Q to use for multiplexing the UCI carried in the channels in the set Q for multiplexing and transmission. For the specific process, refer to TS38.213. If the PUCCH does not overlap with any PUSCH, the terminal equipment multiplexes the UCI into the PUCCH for transmission. If the PUCCH overlaps with at least one PUSCH, the terminal determines one PUSCH from the at least one PUSCH, and multiplexes the UCI into the PUSCH for transmission, specifically:

1. The acknowledgement (Acknowledgement, ACK)/non-acknowledgement (Non-Acknowledgement, NACK) information carried in the channel in the set Q, and/or the channel state information (Channel State Information, CSI) information is multiplexed for transmission in the PUSCH ;

2. Scheduling Request (SR) information carried in the channels in the set Q is not transmitted.

The process for the terminal device to determine one PUSCH from the above at least one PUSCH includes:

(1) If at least one PUSCH includes a first PUSCH scheduled by downlink control information (Downlink Control Information, DCI) and a second PUSCH configured by high-level signaling (ConfiguredGrantConfig or semiPersistentOnPUSCH), then the determined PUSCH is one of the first PUSCHs For example, if there are multiple first PUSCHs that meet the multiplexing conditions, the terminal device selects the carrier with the smallest corresponding serving cell identifier (Identity, ID) (ServCellIndex) among the carriers where the multiple first PUSCHs are located. The first PUSCH is used as the determined PUSCH.

(2) If there are multiple PUSCHs (that is, multiple first PUSCHs scheduled by DCI or multiple second PUSCHs configured by high-level signaling) that meet the multiplexing conditions, the terminal selects the corresponding serving cell in the carrier where the multiple PUSCHs are located. The PUSCH in the carrier with the smallest ID (ServCellIndex) at the previous time is used as the determined PUSCH.

When the UCI is multiplexed in the PUSCH for transmission, the number of modulation symbols occupied by the UCI in the PUSCH needs to be determined according to the number of bits of the UCI and the configuration information of the PUSCH. Specifically, if the UCI is ACK/NACK information, the number of modulation symbols is:

in:

-O _ACK is the number of ACK/NACK messages

- If O _ACK ≥ 360, L _ACK = 11; otherwise, L _ACK is the number of CRC bits;

-

Configured by higher layer signaling;

-C _UL-SCH is the number of code blocks included in the PUSCH data part;

-K _r is the size of the r-th coding block;

-

is the number of subcarriers occupied by PUSCH;

-

is the number of subcarriers occupied by the PTRS in the orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol 1 in the resource occupied by the PUSCH;

-

is the number of resource elements (Resource Element, RE) used to transmit UCI in OFDM symbol 1 in the resources occupied by PUSCH,

The total number of OFDM included in PUSCH;

- for OFDM symbols carrying DRMS in PUSCH,

- for OFDM symbols in PUSCH that do not carry DRMS,

-α is configured by higher layer signaling scaling;

-l ₀ is the symbol index (index) of the first OFDM symbol in the PUSCH that is not used for transmitting DMRS.

To ensure the reliability of the ACK/NACK information, the ACK/NACK information is mapped from the first OFDM symbol that does not carry DMRS after the earliest demodulation reference signal (DMRS) symbol in the PUSCH, occupying Q′ _ACK For RE transmission, one modulation symbol is mapped to one RE, so the number of modulation symbols is equal to the number of REs.

In NR Rel-16, in order to better support Ultra Reliable Low Latency (Ultra Reliable Low Latency, URLLC) services. The physical channel can be configured with 2-level priority, that is, high priority or low priority. Usually URLLC traffic will use high priority channel for transmission. If there are multiple uplink channels with different priorities overlapping, for channels with the same priority, the terminal device uses the Rel-15 working mechanism to determine a multiplexing channel (if there is only one priority channel, the so-called multiplexing channel is the channel itself ), that is, the terminal device obtains two multiplexed channels corresponding to different priorities respectively. If the multiplexed channels of different priorities overlap, the terminal device only transmits the multiplexed channels of high priority and discards the channels of low priority. Where HP means high priority and LP means low priority.

Specifically, FIG. 3 is a schematic diagram of multiplexing channels with different priorities. As shown in the upper part of FIG. 3 , the high-priority channels include: PUCCH carrying URLLC SR, PUCCH carrying URLLC ACK/NACK, and services carrying URLLC PUSCH of data, low priority channel includes: PUCCH carrying eMBB ACK/NACK and PUCCH carrying CSI. In step 1, for the high-priority channel, the PUCCH carrying the URLLC ACK/NACK and the PUSCH carrying the service data of the URLLC overlap. Therefore, the terminal device adopts the working mechanism of Rel-15 to determine that the PUSCH is a multiplexing channel, that is, the PUSCH The traffic data and ACK/NACK of URLLC can be transmitted, and the multiplexing channel can be described as a high-priority multiplexing channel. For low-priority channels, the PUCCH carrying eMBB ACK/NACK and the PUCCH carrying CSI overlap. Therefore, the terminal device adopts the working mechanism of Rel-15 to determine that the PUCCH carrying CSI is a multiplexed channel, that is, the PUCCCH can transmit eMBB ACK/NACK. NACK and CSI, the multiplexed channel can be described as a low-priority multiplexed channel. Since the high-priority multiplexing channel and the low-priority multiplexing channel do not overlap, the terminal device does not only transmit the high-priority multiplexing channel and discard the low-priority channel.

The difference between the lower part and the upper part of Figure 3 is that the high-priority multiplexing channel and the low-priority multiplexing channel shown in the lower part overlap. Therefore, in step 2, the terminal device only transmits the high-priority multiplexing channel. Multiplex channels with higher priority and discard lower priority channels.

In order to further reduce the delay, Rel-16 introduces a sub-slot (sub-slot) for PUCCH, which is configured by the high-level signaling subslotLength-ForPUCCH,a. For regular Cyclic Prefix (CP), the currently supported sub-slot length is 2 or 7 symbols. For extended CP, the currently supported sub-slot length is 2 or 6 symbols. For PUCCH transmitted based on sub-slots, its time domain resources cannot cross the boundary of sub-slots, that is, a sub-slot PUCCH can only be transmitted in one sub-slot. The sub-slot is only used to constrain the PUCCH transmission, but does not restrict the scheduling of the PUSCH, that is, the time domain resources used by the PUSCH do not need to be guaranteed to be within one sub-slot.

In NR Rel-16, if the uplink channels of different priorities overlap, the terminal equipment discards the low-priority uplink channels and only transmits the high-priority channels. The advantage of this is that the transmission delay requirement and reliability of the high-priority channel are guaranteed. However, considering that low-priority channels are usually used to transmit eMBB services with a large amount of data in practical applications, discarding low-priority channels will cause retransmission of a large amount of data, thereby reducing system transmission efficiency.

In order to solve the above technical problem, the present application multiplexes the UCI of the high-priority PDCCH into the low-priority PUSCH for transmission when the time-domain relationship of the high-priority PDCCH of the low-priority PUSCH meets a preset condition.

The technical solutions of the present application are described in detail below:

FIG. 4 is an interaction flowchart of a wireless communication method provided by an embodiment of the present application, and the method includes the following steps:

Step S410: If the PUCCH and the PUSCH overlap, and the time domain relationship between the PUCCH and the PUSCH satisfies the preset condition, the terminal device multiplexes the UCI in the PUCCH into the PUSCH for transmission. The priority of PUCCH is higher than that of PUSCH.

The PUCCH in step S410 is also described as a high-priority PUCCH, and the PUSCH is also described as a low-priority PUSCH.

It should be understood that, in this application, any two channels overlapping may be any two channels partially or completely overlapping in the time domain. For example, FIG. 5 is a schematic diagram of a PUCCH and a PUSCH provided by an embodiment of the present application, wherein the PUCCH and the PUSCH partially overlap in the time domain.

Optionally, the preset conditions include any of the following, but are not limited to:

1. The end position of the resources used to carry UCI in the PUSCH is not later than the end position of the PUCCH;

2. The end position of the maximum number of resources that can be used to carry UCI in the PUSCH is not later than the end position of the PUCCH;

3. The end position of the maximum number of resources that can be used to carry UCI in the PUSCH is not later than the end position of the PUCCH;

4. The end position of the maximum number of resources that can be used to carry UCI in the PUSCH is not later than the end position of the time slot or sub-slot where the PUCCH is located.

Optionally, in this application, the resources may be REs or modulation symbols.

It should be understood that, in this application, the end position refers to the end position in the time domain.

It should be understood that the above-mentioned preset conditions may also include the aforementioned multiplexing timing relationship. For the definition of the multiplexing timing relationship, please refer to TS38.213, which will not be repeated in this application.

The following describes the four conditions included in the above preset conditions:

For the sake of convenience, the four conditions included in the above preset conditions are referred to as condition 1, condition 2, condition 3 and condition 4, respectively.

Explain for condition 1:

The end position of the resources used to carry UCI in the PUSCH is not later than the end position of the PUCCH, which is also described as the end position of the time domain symbols occupied by the UCI in the PUSCH not later than the end position of the PUCCH.

Exemplarily, FIG. 6 is a schematic diagram of PUCCH and PUSCH provided by another embodiment of the present application. As shown in FIG. 6 , the first time-domain symbol in the low-priority PUSCH is used to transmit DMRS, and the following three time-domain symbols are used to transmit DMRS. The symbol is the time domain symbol before the end of the PUCCH, and the UCI is transmitted on some resources on the first time domain symbol and the second time domain symbol among the three time domain symbols. The end position of the resources of the UCI is earlier than the end position of the PUCCH.

It should be noted that the end position of the resources used to carry UCI in the PUSCH is not later than the end position of the PUCCH, then the number of resources occupied by the UCI in the PUSCH needs to be less than or equal to the first number, which is not in the PUSCH. The number of resources available for UCI transmission in time domain symbols later than the end position of the PUCCH.

Specifically, it is assumed that the number of resources occupied by the UCI in the PUSCH is represented by Q, and the above-mentioned first number is represented by P. Wherein, the terminal device may determine Q=Q' _ACK according to the number of bits of UCI, wherein, if the UCI is ACK/NACK information, Q' _ACK may be determined according to formula (1). If the UCI is CSI information, or ACK/NACK information and CSI information, Q' _ACK can be determined according to the reference formula (1), which is not repeated in this application. where Q needs to be less than or equal to P,

l _end is the index of the PUCCH end symbol (ie, the end position). For the meaning of other parameters, please refer to the relevant content of formula (1). The physical meaning of P is the number of resources available for UCI transmission in the time domain symbol in the PUSCH not later than the end position of the high-priority PUCCH.

Exemplarily, as shown in FIG. 6 , the number Q of resources occupied by the UCI in the PUSCH determined by the terminal device is less than P, where P is the number of resources in the three time domain symbols following the DMRS in FIG. 6 .

Explain for condition 2:

The end position of the maximum number of resources that can be used to carry UCI in PUSCH is not later than the end position of PUCCH, which is also described as the end position of the time domain symbols occupied by the resources that can be used to transmit the UCI in low-priority PUSCH. at the end of the high-priority PUCCH.

Exemplarily, FIG. 7 is a schematic diagram of PUCCH and PUSCH provided by another embodiment of the present application. As shown in FIG. 7 , the first time-domain symbol in the low-priority PUSCH is used to transmit DMRS, and the following three time-domain symbols are used to transmit DMRS. The symbol is the time domain symbol before the end of the PUCCH, and the part of the resources on the first time domain symbol, the second time domain symbol and the third time domain symbol among the three time domain symbols is the largest available for carrying UCI. It can be seen that the end position of the maximum number of resources that can be used to carry UCI in the PUSCH shown in FIG. 7 is not later than the end position of the PUCCH.

It should be noted that the end position of the maximum number of resources that can be used to carry UCI in the PUSCH is not later than the end position of the PUCCH, then the above maximum number needs to be less than or equal to the first number, and the first number is not later than the PUCCH in the PUSCH. The number of resources available to transmit UCI in the time-domain symbols at the end position.

Specifically, it is assumed that the above-mentioned maximum number is represented by T, and the above-mentioned first number is represented by P. in,

If T is less than or equal to P,

Exemplarily, as shown in FIG. 7 , the maximum number T of resources available for UCI in the PUSCH is less than P, where T is the first time domain symbol, the second time domain symbol and the following DMRS in FIG. 7 . The number of resources included in the partial resources on the third time-domain symbol, P is the number of resources in the three time-domain symbols following the DMRS in FIG. 7 .

It is worth mentioning that using the method corresponding to Condition 1 and the method corresponding to Condition 2 can ensure that the transmission delay of the UCI multiplexed and transmitted on the low-priority PUSCH is equivalent to that of the single transmission through the PUCCH. Compared with the method corresponding to condition 1, the method corresponding to condition 2 has the advantage that the value of parameter T is independent of the number of bits of UCI, and the terminal device does not need to wait until the number of bits of all UCI is determined before making multiplexing judgment. Therefore, the condition 2 The corresponding method is relatively simple to implement. In addition, the method corresponding to Condition 2 will not cause inconsistent judgment results on the multiplexing result because the network device and the terminal device have inconsistent understandings of the number of UCI bits. However, the disadvantage of the method corresponding to condition 2 is that condition 2 is relatively loose, which reduces the probability of multiplexing transmission. For example, usually Q is less than or equal to T. If the method corresponding to condition 1 is used, the terminal device can multiplex and transmit UCI, but if the method corresponding to condition 2 is used, the terminal device may not be able to multiplex and transmit UCI.

Explain for condition 3:

The end position of the resources used to carry UCI in the PUSCH is not later than the end position of the time slot or sub-slot where the PUCCH is located, which is also described as the end position of the time domain symbol occupied by the UCI in the PUSCH. The end position is not later than the high priority The end position of the slot or subslot where the PUCCH is located.

Exemplarily, FIG. 8 is a schematic diagram of PUCCH and PUSCH provided by another embodiment of the present application. As shown in FIG. 8 , the first time domain symbol in the low priority PUSCH is used to transmit DMRS, and the following four time domain symbols are used to transmit DMRS. The symbol is the time domain symbol before the end of the subslot where the PUCCH is located, and the UCI is transmitted on some resources on the first time domain symbol and the second time domain symbol in the four time domain symbols. It can be seen that, The end position of the UCI resource shown in FIG. 8 is earlier than the end position of the subslot where the PUCCH is located.

It should be noted that the end position of the resources used to carry UCI in the PUSCH is not later than the end position of the time slot or sub-slot where the PUCCH is located, then the number of resources occupied by the UCI in the PUSCH needs to be less than or equal to the second number , and the second quantity is the quantity of resources available for transmitting UCI in the time domain symbol in the PUSCH no later than the end position of the time slot or subslot where the PUCCH is located.

Specifically, it is assumed that the number of resources occupied by the UCI in the PUSCH is represented by Q, and the above-mentioned second number is represented by P1. Wherein, the terminal device may determine Q=Q' _ACK according to the number of bits of UCI, wherein, if the UCI is ACK/NACK information, Q' _ACK may be determined according to formula (1). If the UCI is CSI information, or ACK/NACK information and CSI information, Q' _ACK can be determined according to the reference formula (1), which is not repeated in this application. where Q needs to be less than or equal to P', where,

l' _end is the index of the end symbol of the time slot or sub-slot where the PUCCH is located, and the meaning of other parameters can be found in the relevant content of formula (1). The physical meaning of P' is the number of resources available for UCI transmission in the time domain symbol in the PUSCH not later than the end position of the time slot or sub-slot where the high-priority PUCCH is located.

Exemplarily, as shown in FIG. 8 , the number Q of resources occupied by the UCI in the PUSCH determined by the terminal device is less than P', where P' is the number of resources in the four time domain symbols following the DMRS in FIG. 8 . quantity.

It should be understood that since the PUCCH itself is transmitted based on the sub-slot granularity, the transmission delay caused by aligning the transmission end position of the UCI carried in the PUCCH with the sub-slot end position is acceptable. Compared with Condition 1 and Condition 2, Condition 3 is relatively loose, so the probability of multiplexing transmission can be improved.

Explain for condition 4:

The end position of the maximum number of resources that can be used to carry UCI in the PUSCH is not later than the end position of the time slot or sub-slot where the PUCCH is located, which is also described as the time domain occupied by the resources that can be used to transmit UCI in the low-priority PUSCH The end position of the symbol is not later than the end position of the slot or subslot where the high-priority PUCCH is located.

Exemplarily, FIG. 9 is a schematic diagram of PUCCH and PUSCH provided by another embodiment of the present application. As shown in FIG. 9 , the first time domain symbol in the low priority PUSCH is used to transmit DMRS, and the following four time domain symbols are used to transmit DMRS. The symbol is the time domain symbol before the end of the subslot where the PUCCH is located, and some resources on the first time domain symbol, the second time domain symbol and the third time domain symbol among the four time domain symbols are available. It can be seen that the end position of the maximum number of resources that can be used to carry UCI in the PUSCH shown in FIG. 9 is not later than the end position of the time slot or subslot where the PUCCH is located.

It should be noted that the end position of the maximum number of resources that can be used to carry UCI in the PUSCH is not later than the end position of the time slot or sub-slot where the PUCCH is located, then the above maximum number needs to be less than or equal to the second number, the second number It is the number of resources available for UCI transmission in the time domain symbol in the PUSCH not later than the end position of the time slot or sub-slot where the PUCCH is located.

Specifically, it is assumed that the above-mentioned maximum number is represented by T, and the above-mentioned second number is represented by P'. in,

If T is less than or equal to P', where,

Exemplarily, as shown in FIG. 9 , the maximum number T of resources available for UCI transmission in the PUSCH is less than P′, where T is the first time domain symbol and the second time domain symbol following the DMRS in FIG. 9 . The number of resources included in the symbol and the partial resources on the third time-domain symbol, P' is the number of resources in the four time-domain symbols following the DMRS in FIG. 9 .

It is worth mentioning that since the PUCCH itself is transmitted based on the sub-slot granularity, the transmission delay caused by aligning the transmission end position of the UCI carried in the PUCCH with the end position of the sub-slot is acceptable. . Compared with

conditions

1 and 2, condition 4 is relatively loose, so the probability of multiplexing transmission can be improved.

Compared with the method corresponding to condition 3, the value of parameter T in the method corresponding to condition 4 has nothing to do with the number of UCI bits, and the terminal device does not need to wait until the number of bits of all UCIs is determined before performing multiplexing judgment, which is relatively simple to implement. In addition, because the network device and the terminal device have inconsistent understanding of the bit quantity of the UCI, the result of the multiplexing result judgment will not be inconsistent. But it will reduce the probability of multiplexing transmission. For example, usually Q is less than or equal to T. If the method corresponding to condition 3 is used, the terminal device can multiplex and transmit UCI, but if the method corresponding to condition 4 is used, the terminal device may not be able to multiplex and transmit UCI.

To sum up, in this application, if the high-priority PUCCH overlaps with the low-priority PUSCH, and the time-domain relationship between the PUCCH and the PUSCH satisfies the above preset conditions, the terminal device multiplexes the UCI in the PUCCH into the PUSCH transfer in. That is, in this application, multiplexing and transmission of information carried by channels with different priorities is supported, so as to reduce the probability of discarding low-priority channels and improve system efficiency. Further, when the time domain relationship between the high-priority PUCCH and the low-priority PUSCH satisfies the above preset conditions, the high-priority information, that is, the UCI delay requirement and reliability requirement can be guaranteed.
