Before the technical scheme of the application is introduced, the related technology of the application is introduced as follows:

NR Rel-15 specifies that a plurality of Physical Uplink Control Channels (PUCCH) or a plurality of PUCCH and Physical Uplink Shared Channels (PUSCH) are multiplexed into one Channel for transmission when they satisfy a multiplexing timing relationship, where the multiplexing timing relationship is defined in TS38.213. Otherwise, the terminal device may determine that the situation is an abnormal situation. The multiplexing timing relationship here is mainly to ensure that the terminal device has enough time to determine whether Information carried by different Uplink channels needs to be multiplexed, and time required for Uplink Control Information (UCI) concatenation, encoding, and the like during multiplexing transmission.

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

1. determining that the PUCCH A: the earliest PUCCH in the overlapping channels is started. And if a plurality of PUCCHs with the same start are available, taking the PUCCH with the longest duration. Both are the same, optionally one.

2. PUCCH overlapping PUCCH a includes set Q.

3. PUCCHs overlapping any PUCCH in set Q are included in set Q.

4. And multiplexing UCI in all the sets Q in one PUCCH, and determining PUCCH B according to the bit number of the UCI and PUCCH Resource indication information (PRI).

The terminal device determines whether PUCCH B overlaps with other PUCCH. If yes, repeatedly executing 1-4. 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 UCI for multiplexing the intra-channel bearers in the transmission set Q according to one PUCCH determined for the set Q, for a specific procedure see TS38.213. And if the PUCCH does not overlap any PUSCH, the terminal equipment multiplexes the UCI in 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 UCI in the PUSCH for transmission, specifically:

1. acknowledgement (ACK)/Non-Acknowledgement (NACK) Information of an intra-Channel bearer in the set Q, and/or Channel State Information (CSI) Information is multiplexed for the intra-PUSCH transmission;

2. scheduling Request (SR) information carried within a channel in the set Q is not transmitted.

The process that the terminal equipment determines one PUSCH from the at least one PUSCH comprises the following steps:

(1) If at least one PUSCH includes a first PUSCH scheduled by Downlink Control Information (DCI) and a second PUSCH configured by a higher layer signaling (configurable grant configuration or semipersistent onpusch), the determined PUSCH is one of the first PUSCHs, for example, if a plurality of first PUSCHs satisfy a multiplexing condition, the terminal device selects a first PUSCH in which a corresponding serving cell Identity (Identity, ID) (ServCellIndex) is located in a carrier where the plurality of first PUSCHs are located, and the first PUSCH in which the time in the carrier where the corresponding serving cell Identity (ID) (ServCellIndex) is the smallest is taken as the determined PUSCH.

(2) If a plurality of PUSCHs (namely a plurality of first PUSCHs scheduled by DCI or a plurality of second PUSCHs configured by higher-layer signaling) meet the multiplexing condition, the terminal selects the PUSCH with the time before the corresponding intra-carrier time with the smallest serving cell ID (ServcCellIndex) from the carriers of the plurality of PUSCHs 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 UCI is ACK/NACK information, the number of modulation symbols is:

wherein:

-O _ACK for the amount of ACK/NACK information

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

-

configured by higher layer signaling;

-C _UL-SCH the number of code blocks included for the PUSCH data portion;

-K _r the size of the r coding block;

-

the number of subcarriers occupied by the PUSCH;

-

the number of subcarriers occupied by the PTRS in an Orthogonal Frequency Division Multiplexing (OFDM) symbol l in a resource occupied by the PUSCH;

-

the number of Resource Elements (REs) used for transmitting UCI in OFDM symbol l in the resources occupied by PUSCH,

total number of OFDM included in PUSCH;

for OFDM symbols carrying DRMS in PUSCH,

for no bearer in PUSCHThe OFDM symbols of the DRMS are,

- α is configured by higher layer signaling scaling;

-l ₀ a symbol index (index) of the first OFDM symbol in the PUSCH not used for transmission of DMRS.

To ensure the reliability of the ACK/NACK information, the ACK/NACK information is mapped from the first OFDM symbol which does not carry the DMRS and is after the earliest Demodulation Reference Signal (DMRS) symbol in the PUSCH, and occupies Q' _ACK One RE is transmitted and 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, ultra Reliable Low Latency (URLLC) traffic is supported for better support. The physical channel may be configured with a level 2 priority (2-level priority), i.e., high priority or low priority. Typically URLLC traffic will be transmitted using a high priority channel. If there are multiple uplink channels with different priorities overlapped, for the channels with the same priority, the terminal device determines a multiplexing channel by using the working mechanism of Rel-15 (if there is only one priority channel, the multiplexing channel is the channel itself), that is, the terminal device obtains two multiplexing channels corresponding to different priorities respectively. If the multiplexing channels with different priorities are overlapped, the terminal equipment only transmits the multiplexing channel with high priority and discards the multiplexing channel with low priority. Where HP represents high priority and LP represents low priority.

Specifically, fig. 3 is a schematic diagram of multiplexed channels with different priorities, and as shown in the upper half of fig. 3, a high-priority channel includes: PUCCH for bearing URLLC SR, PUCCH for bearing URLLC ACK/NACK and PUSCH for bearing URLLC service data, the low priority channel comprises: PUCCH carrying eMBB ACK/NACK and PUCCH carrying CSI. In step 1, for a high priority channel, the PUCCH carrying URLLC ACK/NACK and the PUSCH carrying URLLC traffic data overlap, so the terminal device determines that the PUSCH is a multiplexing channel by using the working mechanism of Rel-15, that is, the PUSCH can transmit the URLLC traffic data and ACK/NACK, and the multiplexing channel can be described as a high priority multiplexing channel. For a low-priority channel, a PUCCH carrying eMBB ACK/NACK and a PUCCH carrying CSI are overlapped, so that the terminal device determines that the PUCCH carrying CSI is a multiplexed channel by using a Rel-15 working mechanism, that is, the PUCCCH can transmit eMBB ACK/NACK and CSI, and the multiplexed channel can be described as a low-priority multiplexed channel. Because the high-priority multiplexing channel and the low-priority multiplexing channel are not overlapped, the terminal equipment does not have the situation that only the high-priority multiplexing channel is transmitted and the low-priority channel is discarded.

Wherein the lower half and the upper half of fig. 3 differ in that: the high priority multiplexed channel and the low priority multiplexed channel shown in the lower half overlap, and therefore, in step 2, the terminal device transmits only the high priority multiplexed channel and discards the low priority channel.

Rel-16 introduces a sub-slot (sub-slot) for PUCCH in order to further reduce time delay, and the sub-slot is configured by high layer signaling sub-slot-ForPUCCH, a. For a conventional Cyclic Prefix (CP), the sub-slot length currently supported is 2 or 7 symbols. For extended CP, the sub-slot length supported currently is 2 or 6 symbols. The time domain resources of the PUCCH based on sub-slot transmission cannot cross the boundary of the sub-slot, namely, one sub-slot PUCCH can only transmit in one sub-slot. The subslot is only used for restricting the PUCCH transmission, and the scheduling of the PUSCH is not limited, namely the time domain resource used by the PUSCH does not need to be guaranteed in one subslot.

If the uplink channels with different priorities are overlapped in NR Rel-16, the terminal equipment discards the uplink channel with low priority and only transmits the uplink channel with high priority. This has the advantage that the transmission delay requirement and reliability of the high priority channel are guaranteed. However, considering that the low-priority channel is generally used for transmitting the eMBB service with a large data volume in practical applications, discarding the low-priority channel may cause retransmission of a large amount of data, thereby reducing system transmission efficiency.

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

The technical scheme of the application is explained in detail as follows:

fig. 4 is an interaction flowchart of a wireless communication method according to an embodiment of the present application, where the method includes the following steps:

step S410: and if the PUCCH and the PUSCH are overlapped and the time domain relation of the PUCCH and the PUSCH meets the preset condition, the terminal equipment multiplexes the UCI in the PUCCH into the PUSCH for transmission. Wherein the priority of the PUCCH is higher than that of the PUSCH.

Here, 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 the present application, any two channels overlap may be that any two channels partially overlap or completely overlap in the time domain. For example: fig. 5 is a schematic diagram of a PUCCH and a PUSCH provided in an embodiment of the present application, where the PUCCH and the PUSCH partially overlap in a time domain.

Optionally, the preset condition includes any one of, but is not limited to:

1. the end position of the resource for bearing the UCI in the PUSCH is not later than the end position of the PUCCH;

2. the end position of the maximum number of resources which can be used for bearing the UCI in the PUSCH is not later than the end position of the PUCCH;

3. the end position of the maximum number of resources which can be used for bearing the UCI in the PUSCH is not later than the end position of the PUCCH;

4. the end position of the maximum number of resources available for carrying the UCI in the PUSCH is not later than the end position of the slot or the sub-slot of the PUCCH.

Alternatively, in the present application, the resource may be an RE or a modulation symbol.

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 preset condition may also include the aforementioned multiplexing timing relationship, and the definition of the multiplexing timing relationship may be referred to as TS38.213, which is not described in detail herein.

The following description will be made for 4 conditions included in the preset conditions:

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

The following describes condition 1:

the end position of the resource for carrying the UCI in the PUSCH is not later than the end position of the PUCCH, and is also described as the end position of the time domain symbol occupied by the UCI in the PUSCH is not later than the end position of the PUCCH.

Exemplarily, fig. 6 is a schematic diagram of a PUCCH and a PUSCH according to another embodiment of the present invention, as shown in fig. 6, a first time domain symbol in a low-priority PUSCH is used for transmitting a DMRS, and the following 3 time domain symbols are time domain symbols before the PUCCH ends, and UCI is transmitted on partial resources on the first time domain symbol and the second time domain symbol in the 3 time domain symbols, so that the ending position of the resource of UCI shown in fig. 6 is earlier than the ending position of the PUCCH.

It should be noted that the end position of the resource for carrying the UCI in the PUSCH is not later than the end position of the PUCCH, so the number of resources occupied by the UCI in the PUSCH needs to be less than or equal to a first number, where the first number is the number of resources available for transmitting the UCI in the time domain symbol that is not later than the end position of the PUCCH in the PUSCH.

Specifically, it is assumed that the number of resources occupied by UCI in PUSCH is denoted by Q, and the first number is denoted by P. Wherein, the terminal device may determine Q = Q 'according to the bit number of the UCI' _ACK Wherein, if UCI is ACK/NACK information, Q' _ACK Can be determined according to equation (1). Q 'if UCI is CSI information or ACK/NACK information and CSI information' _ACK Can be determined according to the reference formula (1), which is not described in detail herein. Wherein Q needs to be less than or equal to P,

l _end for the index of the PUCCH end symbol (i.e. end position), other parameter meanings can be referred to in the relevant content of equation (1). The physical meaning of P is the number of resources available for transmitting UCI in the time domain symbol no later than the end position of the high priority PUCCH in PUSCH.

Illustratively, as shown in fig. 6, the number Q of resources occupied by UCI in PUSCH determined by the terminal device is smaller than P, where P is the number of resources in 3 time domain symbols after DMRS in fig. 6.

The following describes condition 2:

the end position of the maximum number of resources available for carrying the UCI in the PUSCH is no later than the end position of the PUCCH, and is also described as the end position of the time domain symbol occupied by the resources available for transmitting the UCI in the low-priority PUSCH is no later than the end position of the high-priority PUCCH.

For example, fig. 7 is a schematic diagram of a PUCCH and a PUSCH according to still another embodiment of the present application, as shown in fig. 7, a first time domain symbol in a low-priority PUSCH is used to transmit a DMRS, the following 3 time domain symbols are time domain symbols before the PUCCH ends, and partial resources on the first time domain symbol, the second time domain symbol, and the third time domain symbol in the 3 time domain symbols are the maximum number of resources available for carrying UCI, and thus, an end position of the maximum number of resources available for carrying UCI in the PUSCH shown in fig. 7 is not later than an end position of the PUCCH.

It should be noted that the end position of the maximum number of resources in the PUSCH that can be used to carry the UCI is not later than the end position of the PUCCH, and then the maximum number needs to be smaller than or equal to the first number, which is the number of resources available for transmitting the UCI in the time domain symbols that are not later than the end position of the PUCCH in the PUSCH.

Specifically, it is assumed that the maximum number is denoted by T and the first number is denoted by P. Wherein the content of the first and second substances,

if T is less than or equal to P,

l _end for the index of the PUCCH end symbol (i.e. end position), other parameter meanings can be referred to in the relevant content of equation (1). The physical meaning of P is the number of resources available for transmitting UCI in time domain symbols in PUSCH that are no later than the end position of the high priority PUCCH.

Illustratively, as shown in fig. 7, the maximum number T of resources available for UCI in PUSCH is smaller than P, where T is the number of resources included in the part of resources on the first time domain symbol, the second time domain symbol and the third time domain symbol after the DMRS in fig. 7, and P is the number of resources in the 3 time domain symbols after the DMRS in fig. 7.

It is worth mentioning that the method corresponding to condition 1 and the method corresponding to condition 2 may ensure that the transmission delay of the UCI multiplexed and transmitted on the low-priority PUSCH is equivalent to the delay of separate transmission through the PUCCH. Compared with the method corresponding to the condition 1, the method corresponding to the condition 2 has the advantages that the value of the parameter T is independent of the bit number of the UCI, and the terminal device does not need to wait until the bit number of all the UCI is determined to perform multiplexing judgment, so that the method corresponding to the condition 2 is simpler to implement. In addition, the method corresponding to the condition 2 does not cause the situation that the judgment result of the multiplexing result is inconsistent because the network device and the terminal device understand the number of the bits of the UCI inconsistent. However, the method corresponding to the condition 2 has the disadvantage that the condition 2 is relatively loose, and the probability of multiplexing transmission is reduced. For example: generally, Q is less than or equal to T, and if the method corresponding to condition 1 is adopted, the terminal device may perform multiplexing transmission on UCI, but if the method corresponding to condition 2 is adopted, the terminal device may not perform multiplexing transmission on UCI.

The following describes condition 3:

the end position of the resource for carrying the UCI in the PUSCH is not later than the end position of the slot or sub-slot where the PUCCH is located, and is also described as the end position of the time domain symbol occupied by the UCI in the PUSCH is not later than the end position of the slot or sub-slot where the high priority PUCCH is located.

Exemplarily, fig. 8 is a schematic diagram of a PUCCH and a PUSCH according to another embodiment of the present invention, as shown in fig. 8, a first time domain symbol in a low-priority PUSCH is used for transmitting a DMRS, and the following 4 time domain symbols are time domain symbols before an end of a sub-slot where the PUCCH is located, and UCI is transmitted on partial resources on the first time domain symbol and the second time domain symbol in the 4 time domain symbols, so that an end position of a resource of UCI shown in fig. 8 is earlier than an end position of the sub-slot where the PUCCH is located.

It should be noted that the end position of the resource for carrying the UCI in the PUSCH is not later than the end position of the slot or the sub-slot where the PUCCH is located, so that the number of the resource occupied by the UCI in the PUSCH needs to be less than or equal to a second number, where the second number is the number of the resource available for transmitting the UCI in the time domain symbol that is not later than the end position of the slot or the sub-slot where the PUCCH is located in the PUSCH.

Specifically, it is assumed that the amount of resources occupied by UCI in PUSCH is denoted by Q, and the above-mentioned second amount is denoted by P1. Wherein, the terminal device may determine Q = Q 'according to the bit number of the UCI' _ACK Wherein, if UCI is ACK/NACK information, Q' _ACK Can be determined according to equation (1). Q 'if UCI is CSI information or ACK/NACK information and CSI information' _ACK Can be determined according to the reference formula (1), which is not described in detail herein. Wherein Q needs to be less than or equal to P', wherein,

l' _end for the index of the ending symbol of the slot or sub-slot where the PUCCH is located, other parameter meanings can be referred to in the relevant content of equation (1). The physical meaning of P' is the number of resources available for transmitting UCI in the time domain symbol no later than the end position of the slot or sub-slot where the high priority PUCCH is located in PUSCH.

Exemplarily, as shown in fig. 8, the number Q of resources occupied by UCI in PUSCH determined by the terminal device is smaller than P ', where P' is the number of resources in 4 time domain symbols after DMRS in fig. 8.

It should be understood that, since the PUCCH itself is transmitted based on 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. Condition 3 is relatively more relaxed than

conditions

1 and 2, and thus the probability of multiplexing transmission can be improved.

The following describes condition 4:

the end position of the maximum number of resources available for carrying UCI in the PUSCH is not later than the end position of the slot or sub-slot where the PUCCH is located, and it is also described that the end position of the time domain symbol occupied by the resources available for transmitting UCI in the low priority PUSCH is not later than the end position of the slot or sub-slot where the high priority PUCCH is located.

For example, fig. 9 is a schematic diagram of a PUCCH and a PUSCH according to still another embodiment of the present application, as shown in fig. 9, a first time domain symbol in a low-priority PUSCH is used to transmit a DMRS, the following 4 time domain symbols are time domain symbols before the end of a sub-slot where the PUCCH is located, and partial resources on the first time domain symbol, the second time domain symbol, and the third time domain symbol in the 4 time domain symbols are resources with the maximum number that can be used to carry UCI, and thus it can be known that an 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 an end position of the slot or the sub-slot where the PUCCH is located.

It should be noted that the end position of the maximum number of resources in the PUSCH that can be used for carrying the UCI is not later than the end position of the slot or sub-slot in which the PUCCH is located, so that the maximum number needs to be smaller than or equal to the second number, where the second number is the number of resources available for transmitting the UCI in the time domain symbol that is not later than the end position of the slot or sub-slot in which the PUCCH is located in the PUSCH.

Specifically, it is assumed that the maximum number is represented by T and the second number is represented by P'. Wherein, the first and the second end of the pipe are connected with each other,

if T is less than or equal to P', wherein,

Illustratively, as shown in fig. 9, the maximum number T of resources available for UCI transmission in PUSCH is smaller than P ', where T is the number of resources included in the partial resources on the first time domain symbol, the second time domain symbol and the third time domain symbol after the DMRS in fig. 9, and P' is the number of resources in the 4 time domain symbols after the DMRS in fig. 9.

It should be noted 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. Condition 4 is relatively relaxed compared to

conditions

1, 2, and thus the probability of multiplexing transmission can be increased.

Compared with the method corresponding to the condition 3, the value of the parameter T in the method corresponding to the condition 4 is irrelevant to the bit number of the UCI, and the terminal device does not need to wait until the bit number of all the UCI is determined to perform multiplexing judgment, so that the realization is simpler. In addition, the inconsistency of the judgment result of the multiplexing result caused by the inconsistency of the network equipment and the terminal equipment in the bit quantity understanding of the UCI is avoided. But reduces the probability of multiplexing transmissions. For example: generally, Q is less than or equal to T, and if the method corresponding to condition 3 is adopted, the terminal device may perform multiplexing transmission on UCI, but if the method corresponding to condition 4 is adopted, the terminal device may not perform multiplexing transmission on UCI.

In summary, in the present application, if a high-priority PUCCH and a low-priority PUSCH are overlapped and a time domain relationship between the PUCCH and the PUSCH satisfies the preset condition, the terminal device multiplexes UCI in the PUCCH into the PUSCH for transmission. The method and the device support multiplex transmission of information carried by channels with different priorities, so that the probability of discarding channels with low priorities is reduced, and the system efficiency is improved. Further, when the time domain relation between the PUCCH with high priority and the PUSCH with low priority satisfies the preset condition, the high priority information, that is, the delay requirement and the reliability requirement of the UCI, may be ensured.
