Several basic concepts in the NR standard involved in the embodiments of the present application are briefly introduced below.

In the time domain, the embodiments of this application involve the following basic concepts.

A symbol is the smallest time unit in the time domain structure. For example, in NR, a symbol can be an orthogonal frequency-division multiplexing (OFDM) symbol, or a discrete Fourier transform sequence orthogonal frequency division multiplexing (discrete fourier transform). -spread OFDM, DFT-s-OFDM) symbols.

A time slot (slot) is a time unit in the time domain structure, and one time slot may be equal to 12 symbols, or one time slot may be equal to 14 symbols. In this embodiment of the present application, the number of symbols that can be included in one time slot is not limited, and only one time slot is equal to 14 symbols as an example.

A subframe (subframe) is a time unit in the time domain structure. The duration of each subframe is 1 ms, and each subframe can be divided into several time slots. The corresponding relationship between each subframe and time slot is determined by the parameter set. For example, when the subcarrier spacing (SCS) is 15kHz, 1 subframe is equal to 1 time slot, and when the SCS is 30kHz, 1 subframe is equal to 2 time slot.

NR supports one time slot for uplink transmission, which is recorded as U time slot; also supports one time slot for downlink transmission, which is recorded as D time slot; also supports one time slot for uplink transmission, and also supports one time slot for uplink transmission. Downlink transmission can be performed, which is called a special time slot, and this time slot is denoted as an S time slot, that is, the time slot can be selected for uplink transmission or downlink transmission according to the actual situation. Similarly, for a special time slot, the S time slot, the time slot may include uplink symbols and downlink symbols, or uplink symbols and flexible symbols, or downlink symbols and flexible symbols, or include uplink symbols, downlink symbols and flexible symbols, wherein, Uplink symbols are used for uplink transmission, downlink symbols are used for downlink transmission, and flexible symbols can be used for both uplink transmission and downlink transmission.

When a time division duplex (TDD) system is used, the time slot configuration format of the system may be DDDSU, DDDSUDDSUU, DDDDDDDDUU, and the like.

In the frequency domain, a concept involved in the embodiments of the present application: a subcarrier (subcarrier) is the smallest frequency domain unit in the frequency domain structure.

A resource block (RB) is 12 consecutive subcarriers in one time slot.

The physical resource block (PRB) is used to indicate the relative position of the resource block in actual transmission.

In terms of time-frequency resources, the embodiments of the present application involve the following basic concepts.

A resource element (RE) is the smallest physical unit in the NR standard, and one RE is one subcarrier on one OFDM symbol.

In NR, 1 RB is fixed to include 12 subcarriers, but since there are different subcarrier intervals in NR, the actual bandwidth occupied by RBs corresponding to different subcarrier intervals in the frequency domain is different.

Uplink transmission in NR involves the following basic concepts.

Uplink channels in NR include: physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), and physical random access channel (PRACH).

Uplink signals in NR include: sounding reference signal (SRS), demodulation reference signal (DMRS), and phase-tracking reference signal (PTRS), where the uplink DMRS is carried in the Transmission on the PUCCH or PUSCH occupies part of the resources of the PUCCH or PUSCH, and the uplink PTRS is carried on the PUSCH for transmission and occupies part of the resources of the PUSCH.

PUCCH is used to carry UCI. There are 5 formats of PUCCH, which are PUCCH format 0/1/2/3/4. Among them, the number of UCI bits carried by PUCCH format 0/1 is less than or equal to 2 bits; the number of UCI bits carried by PUCCH format 2/3/4 is greater than 2 bits.

In the time domain, PUCCH format 0/2 has a duration of 1 to 2 OFDM symbols, which is called short PUCCH, and short PUCCH cannot be repeated; while PUCCH format 1/3/4 has a duration of 4 to 14 OFDM symbols, called short PUCCH. For the long PUCCH, the long PUCCH can be repeated in the time domain, and the number of repetitions can be 2/4/8 times.

In the frequency domain, PUCCH format 0/1/4 occupies 1 RB, PUCCH format 2 can occupy an integer number of RBs in {1~16}, and PUCCH format 3 can occupy {1~6,8~10,12, 15,16} an integer number of RBs.

The PUCCH may be a periodic PUCCH, a semi-persistent PUCCH, or a dynamically scheduled PUCCH.

The transmission mode of PUSCH in NR involves the following types.

The first is PUSCH transmission based on dynamic scheduling: based on each PUSCH transmission, the physical layer is used to indicate downlink control information (DCI) for scheduling. That is, when the terminal device receives the uplink scheduling of DCI once, it performs one PUSCH transmission.

Second, PUSCH transmission based on configuration grant (CG) type 1: this is a semi-statically scheduled PUSCH, the terminal device receives the high-level configuration (including the high-level parameter configuredGrantConfig of rrc-ConfiguredUplinkGrant), and does not receive physical layer instructions For DCI, the upper layer configures some semi-persistent time-frequency resources. If the terminal device has uplink data to send, it will send the PUSCH on the semi-persistent time-frequency resources configured by the upper layer; if there is no uplink data to be sent, no data transmission will be performed.

The third type, PUSCH transmission based on configuration permission type 2: the terminal device receives the high-level configuration (the high-level parameter configuredGrantConfig that does not include rrc-ConfiguredUplinkGrant, that is, the high-level configuration received by the terminal device does not have the configuration parameter rrc-ConfiguredUplinkGrant), the semi-persistent high-level configuration Time-frequency resources are selected for use by terminal equipment, and these semi-persistent time-frequency resources are activated or deactivated by DCI. If the DCI indicates activation, the terminal device uses semi-persistent time-frequency resources according to its own data transmission requirements, such as the second PUSCH transmission mode; if the DCI indicates deactivation, these semi-persistent time-frequency resources cannot be used.

The uplink control information UCI in NR involves the following basic concepts.

Hybrid automatic repeat request acknowledgement (HARQ-ACK), including acknowledgement (ACK) and negative acknowledgement (NACK). The UE may multiplex HARQ-ACK information on the PUSCH.

Channel state information (channel state information, CSI), specifically including precoding matrix indicator (precoding matrix indicator, PMI), rank indicator (rank indicator, RI), layer indicator (layer indicator, LI), channel quality information (channel quality indicator) , CQI), CSI-RS (reference signal, RS) resource indicator (CSI-RS resource indicator, CRI), reference signal received power (reference signal received power, RSRP), etc. The CSI can be divided into the first part of the channel state information, CSI part 1, and the second part of the channel state information, CSI part 2. Wherein CSI part 1 may include CRI, RI, broadband CSI of the first TB, sub-band differential CQI of the first TB, etc.; CSI part 1 may include broadband CQI, LI, etc. of the second TB. This embodiment of the present application does not limit which CSI specifically includes CSI part 1 and CSI part 2. When the CSI report on the PUSCH includes two parts, the terminal device can ignore a part of CSI part 2. When the CSI report is transmitted on the PUCCH, if any of the CSI reports consists of two parts, the terminal equipment can ignore part of CSI part 2. CSI reports may be periodic, semi-persistent, or aperiodic. An aperiodic CSI (aperiodic channel state information, ACSI) report can be triggered and sent on the PUSCH; if the PUSCH contains uplink data, the UE multiplexes the ACSI report on the PUSCH.

Scheduling request (SR). UE does not multiplex SR on PUSCH.

Currently, when a terminal device transmits PUCCHs and/or PUSCHs to a radio access network device, overlap may occur. That is, PUCCHs and PUSCHs overlap, or multiple PUCCHs overlap, or multiple PUSCHs overlap. The overlapping of PUCCHs and PUSCHs refers to the overlapping of PUCCHs and PUSCHs in the time domain. Similarly, the meaning of overlapping of multiple PUCCHs and overlapping of multiple PUSCHs is similar to the meaning of overlapping of PUCCHs and PUSCHs. For the sake of brevity, they are not repeated here.

PUCCH and PUSCH may be assigned different priority indices. The priority index 0 represents a smaller priority index, which can also be called a low priority index, and a priority index 1 represents a larger priority index, which can also be called a high priority index. When PUCCHs and/or PUSCHs with different priorities overlap, according to different priority indexes, in most cases, the PUCCHs and/or PUSCHs with priority index 0 are cancelled.

When the same-priority PUCCHs and/or PUSCHs overlap, there are three situations: multiple same-priority PUCCHs overlap, multiple same-priority PUSCHs overlap, and same-priority PUCCHs and PUSCHs overlap.

Before explaining the specific processing methods of the current three overlapping cases, a concept is explained first: the time condition. The time condition is satisfied when the terminal equipment expects the same priority PUCCHs and/or PUSCHs to overlap. Different PUSCH and/or PUCCH transmission modes have different time conditions. Taking the transmission mode of at least one of PUSCH and/or PUCCH as dynamic scheduling as an example, the time condition is that the terminal equipment is receiving the corresponding dynamic scheduling PDCCH or PDSCH. There is sufficient processing time between the last symbol and the terminal device sending the first symbol of the earliest PUSCH and/or PUCCH.

In case 1, if multiple PUCCHs with the same priority overlap, there are different processing methods according to whether the PUCCHs overlap. If the PUCCH is repeated, the PUCCH to be sent is selected first according to the priority rules between different types of UCIs, and then according to the time sooner or later rules.

Case 2, if the PUCCH does not overlap and overlaps with multiple PUSCHs of the same priority, the terminal device selects the PUSCH for multiplexing HARQ feedback information and/or CSI reports according to certain rules. The specific rules are as follows. The following rules are in order. The higher the priority, the higher the priority.

First, the terminal device multiplexes the HARQ feedback information on the PUSCH carrying the ACSI; second, the terminal device multiplexes the HARQ feedback information on the PUSCH corresponding to the first slot in the multiple overlapping PUSCH slots. information and/or CSI reporting; third, multiplexing HARQ feedback information and/or CSI reporting on the dynamically scheduled PUSCH; fourth, multiplexing HARQ feedback on the PUSCH of the serving cell with the smallest serving cell index (ServCellIndex) value information and/or CSI report; fifthly, the earliest PUSCH transmitted by the terminal device in the time slot, where the earliest PUSCH can be understood as the PUSCH corresponding to the earliest symbol in the time slot.

In case 3, if the PUCCH and PUSCH of the same priority overlap, there are different processing methods according to whether the PUCCH is repeated or not. The repetition of the PUCCH is indicated in multiple time slots, and the same PUCCH is repeatedly transmitted in each time slot.

When the PUCCH is repeated, the terminal device will not multiplex the UCI on the PUSCH. When the time condition is met, the PUCCH will be transmitted on the overlapping time slots without the PUSCH; or on the actual repetition of the PUSCH, the PUCCH will be transmitted without the PUSCH. .

When the PUCCH is not repeated, the terminal device will multiplex the UCI in the overlapping PUCCH. If the PUSCH does not carry the UL-SCH and the PUCCH carries the scheduling request, the terminal device does not transmit the PUSCH, but only transmits the PUCCH; In other cases, the terminal device will multiplex the HARQ feedback information and/or CSI report on the selected PUSCH as needed, and will not transmit the scheduling request, that is, the scheduling request will not be multiplexed on the PUSCH, that is, the PUSCH does not carry the scheduling request.

At present, the process of multiplexing UCI on PUSCH is as follows: first, generate a bit sequence according to different UCI types; second, perform code block segmentation and CRC addition according to the bit sequence; third, determine the channel coding method according to the bit sequence ; Fourth, through rate matching, the number of coded modulation symbols of each layer of different types of UCI is obtained, and the rate matching output sequence length of different code blocks is determined according to the number of symbols, and the output bit sequence after rate matching; Fifth, sequential cascade Rate matching of different code blocks outputs bit sequences; sixth, the UE multiplexes the concatenated bit sequences onto the PUSCH.

The second and third specific steps may be as follows: if the number of payloads of the UCI bit sequence is less than or equal to 11 bits, the CRC is not attached, and the channel coding mode of the UCI is determined to be small block long channel coding; if the number of payloads of the UCI bit sequence is greater than or equal to If it is equal to 12 bits, the CRC is attached, and the channel coding mode of the UCI is determined as the Polar code.

Wherein, if the Polar code is used for channel coding, the method of obtaining the number of coded modulation symbols per layer of different types of UCI through rate matching is as follows.

When UCI information is transmitted on the PUSCH and uplink data information is transmitted, the number of coded modulation symbols per layer is calculated according to the following rate matching rules for different types of UCI.

When the UCI information includes the HARQ feedback information but does not include the configuration permission information CG-UCI, the number of coded modulation symbols per layer of the HARQ feedback information is calculated by formula (1), where

Indicates rounded up.

Among them, the physical meaning of the first part of formula (1) is based on the actual number of data bits of the HARQ feedback information (the number of bits before coding O _ACK and the number of CRC check bits L _ACK ), the code rate offset factor

and the code rate of the uplink data to calculate the number of resource elements encoded by the HARQ feedback information.

The physical meaning of (O _ACK +L _ACK )/Q' _ACK is the code rate of UCI,

The physical meaning is the code rate of uplink data,

Indicates the ratio of the uplink data code rate to the UCI code rate. The UCI code rate is less than or equal to the uplink data code rate, which is beneficial to the reliability of UCI in terms of transmission performance.

The physical meaning of the second part of formula (1) is to determine the upper limit of the number of HARQ feedback information resource elements according to the upper limit ratio α of the number of resource elements mapped on the PUSCH by UCI, where

is the total number of resource elements available for transmitting HARQ-ACK on the PUSCH, wherein ₁₀ is the symbol index of the first symbol that does not carry the DMRS after the symbol of the first demodulation reference signal DMRS.

The minimum value of the two parts is taken as the number of modulation symbols per layer Q' _ACK used for HARQ feedback information transmission.

When the UCI information includes configuration permission information CG-UCI, the number of coded modulation symbols per layer used for CG-UCI transmission is Q' _CG-UCI is obtained from formula (2); when the UCI information packets CG-UCI and HARQ feedback , the number of coded modulation symbols for each layer used to transmit HARQ feedback information and CG-UCI is calculated by formula (3).

Wherein O _CG-UCI is the number of bits of CG-UCI, and L _CG-UCI is the number of CRC check bits of CG-UCI.

The CSI information consists of CSI part 1 and CSI part 2, the number of coded modulation symbols per layer of CSI part 1 is calculated by formula (4), and the number of coded modulation symbols of each layer of CSI part 2 is calculated by formula (5).

Wherein, when there is HARQ feedback information in the UCI information but no CG-UCI, and the number of bits of the HARQ feedback information is greater than 2, then Q' _ACK/CG-UCI is Q' _ACK in formula (1). When there is no HARQ feedback information in the UCI information and there is CG-UCI, then Q' _ACK/CG-UCI is Q' _CG -UCI in formula (2). When there is HARQ feedback information and CG-UCI in the UCI information, then Q' _ACK/CG-UCI is Q' _ACK in formula (3).

When there is HARQ feedback information in UCI information but no CG-UCI, and the number of bits of HARQ feedback information is 0/1/2, then Q' _ACK/CG-UCI in formula (4) is

is the number of REs reserved for potential HARQ-ACK transmission in the lth OFDM symbol, Q' _ACK/CG-UCI =Q' _ACK =0 in equation (5).

When UCI information is transmitted on the PUSCH but no uplink data information is transmitted, the number of coded modulation symbols per layer is calculated according to the following rate matching rules for different types of UCI.

When the UCI information includes HARQ feedback information, the number of coded modulation symbols per layer of the HARQ feedback information is calculated by formula (6).

Among them, Q _m is the modulation order, and R is the code rate.

CSI information includes CSI part 1 and CSI part 2, or CSI part 1. When UCI information is transmitted on PUSCH, but uplink data information is not transmitted, if CSI part 2 is determined, the number of coded modulation symbols per layer of CSI part 1 is determined by Equation (7) is calculated, at this time, the number of coded modulation symbols of each layer of CSI part 2 is calculated by Equation (8). If it is determined that there is no CSI part 2, the number of coded modulation symbols per layer of CSI part 1 is calculated by formula (9).

If small-block long channel coding is used, the formula for calculating the number of coded modulation symbols for each layer used for UCI transmission, in units of time slots, corresponds to the calculation formula under Polar channel coding one-to-one. The difference is that in the case of small block long channel coding, the number L of CRC bits of different types of UCIs is all 0.

The following will specifically describe the current mapping rules for multiplexing UCI and UL-SCH on PUSCH with reference to FIG. 2 , FIG. 3 and FIG. 4 . FIG. 2 is a schematic diagram of a current mapping rule for multiplexing UCI and UL-SCH on PUSCH provided by an embodiment of the present application.

The HARQ feedback information of (a), (b), (c) and (d) in FIG. 2 is mapped as when the HARQ feedback information is more than 2 bits, or when the UCI information includes the HARQ feedback information and CG-UCI, then According to the actual size, the mapping is performed sequentially starting from the first available symbol after the DMRS symbol. If the HARQ feedback information and the CG-UCI (if any) can occupy the entire current symbol, the current symbol will be occupied, and then the next symbol will be occupied. If the HARQ feedback information and CG-UCI (if any) are not enough to occupy the entire current symbol, they will be distributed on the frequency domain resources at equal intervals on the current symbol.

S201, the HARQ feedback information and the CG-UCI (if any) in the UCI information are mapped, and the HARQ feedback information and the CG-UCI (if any) are mapped from the first available symbol after the DMRS symbol, as shown in (a) of Figure 2 .

S202, when the HARQ feedback information is greater than 2 bits, or when the UCI information includes the HARQ feedback information and CG-UCI, as shown in (b) of Figure 2, map CSI part 1 sequentially from the first available symbol resource on the PUSCH , where the first available symbol resource is the first available symbol resource on the PUSCH except for the resource elements mapped by the DMRS and HARQ feedback information.

S203, when the HARQ feedback information is greater than 2 bits, or when the UCI information includes the HARQ feedback information and CG-UCI, as shown in (c) of Figure 2, map CSI part 2 sequentially from the first available symbol resource on the PUSCH , where the first available symbol resource is the first available symbol resource on the PUSCH except for the resource elements mapped by DMRS, HARQ feedback information and CSI part 1.

S204, when the HARQ feedback information is greater than 2 bits, or when the UCI information includes the HARQ feedback information and CG-UCI, as shown in (d) of Figure 2, the uplink data is sequentially mapped from the first available symbol resource on the PUSCH, Wherein, the first available symbol resource is the first available symbol resource on the PUSCH except for the resources mapped by DMRS, HARQ feedback information, CSI part 1 and CSI part 2.

The cases of (a), (b), (c) and (d) in Figure 3 are: when the CG-UCI is transmitted on the PUSCH, but there is no HARQ feedback information on the PUSCH, the specific steps are similar to those in Figure 2, but the difference is At S301, the CG-UCI in the UCI information is mapped.

The HARQ feedback information of (a), (b), (c), (d) and (e) in FIG. 4 is mapped to when the HARQ feedback information is any size of 0, 1 or 2 bits, and there is no CG- In the case of UCI, starting from the first available UCI symbol after the DMRS symbol in the PUSCH, PUSCH resources are reserved according to the 2-bit HARQ feedback information, which becomes a reserved area. It should be understood that, since the number of bits represented by each symbol in the resource block depends on the selected modulation order, the number of UCI and uplink data mapping resource elements in the figure is only an example.

S401, the number of resource units that need to be mapped for the HARQ feedback information in the UCI information is reserved, and a resource reservation area of the HARQ feedback information is formed, and the resource reservation area starts from the first available symbol after the DMRS symbol, as shown in Figure 4 ( a) shown.

S402, map the CSI part 1 in the UCI information, when the HARQ feedback information is any size of 0, 1 or 2 bits, as shown in (b) of Figure 4, map sequentially from the first available symbol resource on the PUSCH CSI part 1, bypasses the HARQ feedback information reservation area to ensure that CSI part 1 does not conflict with the HARQ feedback information. The first available symbol resource is the resource unit excluding the reserved area for DMRS and HARQ feedback information, and the first available symbol resource on the PUSCH.

S403, map the CSI part 2 in the UCI information. When the HARQ feedback information is any size of 0, 1 or 2 bits, as shown in (c) of Figure 4, map sequentially from the first available symbol resource on the PUSCH CSI part 2, it is not necessary to bypass the HARQ feedback information reservation area at this time, and the first available symbol resource is the resource unit except DMRS and CSI part 1, and the first available symbol resource on the PUSCH.

S404: Map the uplink data information. When the HARQ feedback information is any size of 0, 1 or 2 bits, as shown in (d) of Figure 4, the uplink data is mapped sequentially from the first available symbol resource on the PUSCH. There is no need to bypass the HARQ feedback information reservation area, where the first available symbol resource is the resource element mapped by excluding DMRS, CSI part 1 and CSI part 2, and the first available symbol resource on the PUSCH.

S405, when the HARQ feedback information is any size of 0, 1, or 2 bits, as shown in (e) of FIG. 4, no matter whether the HARQ feedback information resource reservation area is filled in S403 and S404, the HARQ feedback information resource is reserved. The reserved area will be remapped by the HARQ feedback information, and the mapping position starts from the first symbol of the HARQ feedback information resource reserved area to cover the information already mapped in the reserved area. That is, punch holes on the reserved resources to which CSI part2 and/or uplink data have been mapped.

In most cases, a PUSCH transport block is transmitted on only one slot, and when TBoMS is present, a PUSCH transport block can be transmitted on multiple slots. In scenarios with limited uplink coverage, TBoMS can improve channel coding gain by aggregating smaller packets in multiple time slots. In addition, TBoMS can reduce the number of bits occupied by CRC and save resources. Since a single TB of TBoMS is elongated in the time domain, the number of resource blocks or resource units occupied in the frequency domain can be reduced, thereby improving the power spectral density.

At present, the above-mentioned processing methods of UCI multiplexing on PUSCH are for a single PUSCH transport block to be transmitted in one time slot, while for TBoMS, when the size of the transport block remains unchanged, a single transport block needs to be transmitted in multiple time slots. , resulting in a decrease in the number of available resource units in a single time slot, which leads to a decrease in the number of resource units available for UCI when UCI is multiplexed on PUSCH. If the current processing method of UCI multiplexing on PUSCH is continued, more UCI needs to be discarded bit, will affect the transmission of UCI and uplink data, thereby affecting system performance. Therefore, how to effectively transmit UCI and UL-SCH on TBoMS is an urgent problem to be solved.

Since a single PUSCH transmission block requires multiple time slots for transmission, after the overlap of PUCCH and TBoMS with the same priority and no overlap, if the PUCCH carrying UCI does not meet the time conditions for PUCCH and TBoMS transmission, it is necessary to wait for the end of TBoMS transmission before proceeding. The transmission will cause a long delay in the information in the UCI, which will affect the system performance.

When the PUCCH and TBoMS that do not overlap with the same priority overlap, at present, the terminal device can multiplex the UCI at one transmission opportunity of the TBoMS, but when the time-frequency resources required by the UCI are too large, some UCI bits will be discarded, and the UCI cannot be guaranteed. transmission performance, and the transmission performance of UL-SCH will also be affected. The terminal equipment can also directly cancel the transmission of TBoMS and send PUCCH, but this scheme sacrifices the transmission of UL-SCH to ensure the transmission performance of UCI. The terminal device can also directly puncture the UCI originally scheduled for transmission on the PUCCH on the TBoMS, but without considering other UCI multiplexed in the TBoMS, directly puncturing the TBoMS will affect the transmission performance of other UCIs. Therefore, this application proposes a technical solution that can ensure the transmission performance of UCI and UL-SCH as much as possible.

It should be understood that the message carrying the transmission parameter of the first PUSCH and the transmission parameter carrying the PUCCH are different messages.

For a brief description, in the following description, "TBoMS" represents the first PUSCH, and the first PUSCH may also have other names, which are not limited in this embodiment of the present application.

Among them, the first PUSCH only includes one transport block TB CRC attached on K transmission occasions, it can be understood that the first PUSCH only transmits one PUSCH transport block on K transmission occasions, and the PUSCH carries the uplink data and/or UCI, and only one TB CRC is attached. The second PUSCH has K TB CRCs attached at K transmission occasions, that is, the second PUSCH transmits K PUSCH transport blocks at K transmission occasions, and has K TB CRCs attached, that is, the same PUSCH is attached to K Repeat the transmission K times at the transmission opportunity, where K is a positive integer greater than or equal to 2.

Among them, the physical layer priority of the first PUSCH and PUCCH is the same, that is, the physical layer priority of TBoMS and PUCCH is the same. It can be understood that the priority index of TBoMS and the priority index of PUCCH are the same, that is, when the priority index of TBoMS is the same When it is 0, the priority index of PUCCH is also 0; when the priority index of TBoMS is 1, the priority index of PUCCH is also 1. It should be understood that the priorities of the physical layer here are the same, and it does not limit whether the priorities of TBoMS and PUCCH at the media access control (media access control, MAC) layer are the same.

The physical layer priority can be used to indicate the priority of the performance requirements of the services carried on TBoMS or PUCCH. For example, the priority index can be used to indicate the priority requirements of low latency performance of the services carried on TBoMS or PUCCH. The physical layer priority of PUCCH is different. The priority index of TBoMS is 0, and the priority index of PUCCH is 1, which means that the priority of the service carried on the PUCCH for low-latency performance is higher than that of the service carried on the TBoMS.

The overlapping of TBoMS and PUCCH in the time domain can be understood as the overlapping of resources of TBoMS transmission and PUCCH transmission in the time domain, wherein PUCCH and TBoMS overlap in N transmission occasions, and N is a positive integer. There are various scenarios where N is greater than 1. One scenario is that when the subcarrier spacing of the PUCCH and the subcarrier spacing of the TBoMS are the same, multiple PUCCHs and TBoMS overlap, and the overlapping transmission opportunities are greater than 1. Another scenario is that when the subcarrier spacing of PUCCH and the subcarrier spacing of TBoMS are different, a PUCCH and TBoMS overlap, and the overlapping transmission opportunity is greater than 1. For example, when the subcarrier spacing of PUCCH is 15 kHz and the subcarrier spacing of TBoMS is 30 kHz, the duration of one time slot of PUCCH is twice the duration of one time slot of PUSCH. Another scenario is that when the subcarrier spacing of the PUCCH and the subcarrier spacing of the TBoMS are different, and when multiple PUCCHs and TBoMS overlap, the overlapping transmission opportunities are also greater than 1.

K in the transmission parameter of TBoMS will be described in detail below with reference to FIG. 6 . FIG. 6 is a schematic structural diagram of a first PUSCH provided by an embodiment of the present application, that is, a schematic structural schematic diagram of a TBoMS provided by an embodiment of the present application.

It should be understood that the transmission mode of TBoMS in the embodiment of the present application is the transmission mode of DCI dynamic scheduling as an example, and the embodiment of the present application does not limit the transmission mode of TBoMS.

The frame structure used in the embodiments of the present application takes the frame structure DSUUD as an example to illustrate the transmission of TBoMS. The solutions of the embodiments of the present application may also use other frame structures, and the embodiments of the present application do not limit the frame structure.

It should be understood that the frame structure of DSUUD is a time division multiplexed frame structure. D represents downlink transmission on this time slot or transmission opportunity. U represents uplink transmission on this time slot or transmission opportunity. S represents that downlink transmission can be performed on this time slot or transmission opportunity, and uplink transmission can also be performed on this time slot or transmission opportunity. When the access network device needs to use the time slot or transmission opportunity to send a message to the terminal device, The time slot or transmission opportunity is used for downlink transmission; when the terminal device needs to use the time slot or transmission opportunity to send a message to the access network device, the time slot or transmission opportunity is used for uplink transmission.

The number of transmission opportunities K of TBoMS can be understood as the number K of transmission opportunities in the name of TBoMS, that is, TBoMS is transmitted on consecutive K transmission opportunities, among which, only P transmission opportunities that support uplink transmission in the consecutive K transmission opportunities can perform TBoMS transmission, where P is a positive integer less than or equal to K, as shown in (a) of FIG. 6 .

As shown in (a) of Figure 6, after the terminal device receives the DCI scheduling TBoMS on the downlink time slot, the DCI instructs the TBoMS to transmit on K consecutive time slots. When K is 5, for the frame structure DSUUD, the terminal The device transmits TBoMS in 2 uplink time slots in the frame structure. At this time, the actual number of time slots for transmitting TBoMS is less than the nominal number of time slots for transmitting TBoMS, and the two uplink time slots for transmitting TBoMS are continuous. The time slot in which it is located is numbered, as shown in the figure.

The number of transmission opportunities K of TBoMS can also be understood as the actual number of transmission opportunities K of TBoMS, that is, TBoMS needs to transmit on K transmission opportunities that support uplink transmission across Q consecutive transmission opportunities, where Q is a positive value greater than or equal to K Integer as shown in Fig. 6(b).

As shown in (b) of Figure 6, after the terminal device receives the DCI scheduling TBoMS on the downlink time slot, the DCI instructs the TBoMS to transmit on K uplink time slots. When K is 4, for the frame structure DSUUD, for the TBoMS The time slot in which it is located is numbered. As shown in the figure, the terminal equipment needs to transmit TBoMS, and the second uplink time slot and the third uplink time slot are separated by 3 non-uplink time slots.

It should be understood that the determination of the transmission position of the TBoMS by the terminal device depends on the number of time slots or the number K of transmission opportunities for TBoMS transmission and the frame structure.

S503, the terminal device determines the number of time-frequency resources of the UCI and the number of time-frequency resources of the TBoMS according to the transmission parameters of the PUCCH and the transmission parameters of the TBoMS.

As a possible implementation method, the terminal device can determine different types of UCI according to the UCI type and the number of UCI bits in the transmission parameters of PUCCH, and the parameters such as the scaling parameter α and the rate offset factor β _offset in the transmission parameters of TBoMS. number of time-frequency resources.

As a possible implementation manner, there are the following two manners for determining the number of time-frequency resources of the TBoMS.

Mode 1, the terminal device can use parameters such as the frequency domain resource location, the coding and modulation mode, the number of layers during MIMO transmission, the number of uplink symbols in the overlapping transmission opportunities, and the number N of overlapping transmission opportunities for PUCCH and TBoMS according to the transmission parameters of TBoMS, etc. Determine the number of time-frequency resources for TBoMS.

In the second mode, the terminal device can determine the TBoMS according to the frequency domain resource location, coding and modulation mode, the number of layers during MIMO transmission, the number of uplink symbols in overlapping transmission opportunities, and the number of TBoMS transmission opportunities K in the transmission parameters of TBoMS. The number of time-frequency resources.

S504, the terminal device sends the PUCCH and/or the first PUSCH to the access network device according to the number of time-frequency resources of the UCI and the number of time-frequency resources of the first PUSCH, and the access network device receives the PUCCH and/or the first PUSCH, wherein the first A PUSCH includes only one TB CRC attachment on M transmission occasions, where M is less than or equal to K, and M is a positive integer.

The scheme of multiplexing UCI on TBoMS under different conditions will be described below with reference to FIG. 7 to FIG. 12 .

In the embodiment of the present application, the PUCCH and TBoMS in FIG. 7 to FIG. 12 are transmitted through dynamic scheduling. It should be understood that this transmission method is only an example of the embodiment of the present application. The embodiment of the present application transmits the PUCCH and the TBoMS. The method is not limited.

The frame structure in this embodiment of the present application is DSUUD, and the frame structure of DSUUD is described in detail above to avoid repeated descriptions, and will not be repeated here. The time slot diagrams shown in Figures 7 to 12 are part of the time slot with the frame structure of DSUUD, that is, the DDSUUDDSUUD shown in the figure. The downlink time slots are numbered from left to right, and there are a total of 5 downlink time slots. The special time slots are numbered from left to right, and there are 2 special time slots in total; the uplink time slots are numbered from left to right, and there are 4 downlink time slots in total.

In the embodiments of the present application, UCIs are classified into two categories according to different classification methods.

One classification method is to determine the type of UCI according to whether the UCI meets the time conditions for PUCCH and TBoMS transmission. The first type of UCI is carried on the PUCCH that meets the time conditions for PUCCH transmission and TBoMS transmission, and the second type of UCI is carried on the PUCCH that does not meet the time conditions for PUCCH transmission and TBoMS transmission.

Wherein, satisfying the time condition for PUCCH and TBoMS transmission can be understood that there is sufficient processing time between the terminal device receiving the last symbol of PDCCH or PDSCH corresponding to PUCCH and sending the first symbol of PUCCH and/or TBoMS, And there is sufficient processing time between the last symbol of PDCCH corresponding to TBoMS and the first symbol of PUCCH and/or TBoMS is transmitted.

Meeting the time condition for PUCCH transmission or meeting the time condition for TBoMS transmission can be divided into the following situations.

There is sufficient processing time between the terminal equipment receiving the last symbol of the PDCCH corresponding to the PUCCH and sending the first symbol of the PUCCH and/or TBoMS, which can be understood as when the access network equipment does not need to send downlink data to the terminal equipment. , the DCI carried in the PDCCH sent by the access network equipment to the terminal equipment instructs the terminal equipment to feed back information such as CSI, and the terminal equipment carries the UCI including the CSI in the PUCCH and/or TBoMS and sends it to the access network equipment to meet the time conditions of the PUCCH That is, there is sufficient processing time between the last symbol of the PDCCH and the first symbol of the transmission of the PUCCH and/or TBoMS.

There is sufficient processing time between the terminal equipment receiving the last symbol of the PDSCH corresponding to the PUCCH and sending the first symbol of the PUCCH and/or TBoMS, which can be understood as when the access network equipment needs to send downlink data to the terminal equipment. Two scenarios.

Scenario 1, for the access network device to send the PDSCH to the terminal device through dynamic scheduling, that is, the terminal device needs to receive the PDCCH first, then the PDSCH, and then send the UCI to the access network device in the PUCCH and/or TBoMS. , the time condition of PUCCH is satisfied, that is, there is sufficient processing time between the last symbol of PDSCH and the first symbol of sending PUCCH and/or TBoMS, and the PUCCH contains HARQ-ACK information corresponding to PDSCH reception.

Scenario 2 is for the access network device to send the PDSCH to the terminal device through the semi-static transmission paradigm, that is, after the terminal device receives the PDSCH, the UCI is then carried in the PUCCH and/or TBoMS and sent to the access network device, which satisfies the requirements of the PUCCH. The time condition is that there is sufficient processing time between the last symbol of PDSCH and the first symbol of transmission of PUCCH and/or TBoMS, the PUCCH containing HARQ-ACK information corresponding to PDSCH reception.

There is sufficient processing time between the terminal equipment receiving the last symbol of PDCCH corresponding to TBoMS and sending the first symbol of PUCCH and/or TBoMS. It can be understood that TBoMS is transmitted through dynamic scheduling, that is, the terminal equipment receives After the PDCCH of the TBoMS is dynamically scheduled, the UCI is carried in the PUCCH and/or TBoMS and sent to the access network equipment. The time condition for satisfying the TBoMS is the difference between the last symbol of the PDCCH and the first symbol of the PUCCH and/or TBoMS. sufficient processing time.

The above are the time conditions for satisfying PUCCH or TBoMS respectively. Satisfying the transmission time conditions for PUCCH and TBoMS can be understood that when the access network device sends both the PDCCH or PDSCH corresponding to the PUCCH to the terminal device, and the PDCCH corresponding to the TBoMS to the terminal device, When the terminal device sends the PUCCH and/or TBoMS to the access network device, the time condition must satisfy both the PUCCH transmission time condition and the TBoMS transmission time condition.

Another classification method is to determine the type of UCI according to the type of PUCCH carrying the UCI. The first type of UCI is carried on periodic PUCCH or semi-persistent PUCCH, and the second type is carried on dynamically scheduled PUCCH.

FIG. 7 and FIG. 8 show the transmission scheme of PUCCH and TBoMS when the PUCCH and TBoMS carrying the first type of UCI overlap.

When the PUCCH and TBoMS carrying the first type of UCI overlap at N transmission occasions in the time domain, the first type of UCI can be multiplexed on the TBoMS through rate matching, or cancel the transmission of the PUCCH, or cancel the transmission TBoMS, where N is a positive integer, wherein the multiplexing of the first type of UCI on the TBoMS can be understood as that the first type of UCI is carried on the TBoMS, that is, the first type of UCI is carried on the TBoMS.

As a possible implementation manner, the multiplexing of the first type of UCI on the TBoMS may be to multiplex the first type of UCI on the transmission occasions corresponding to the overlapping parts of the PUCCH carrying the first type of UCI and the TBoMS, that is, at N transmission occasions The first type of UCI is multiplexed, and the N transmission occasions are transmission occasions when the PUCCH and the TBoMS carrying the first type of UCI overlap in the time domain.

As another possible implementation manner, the multiplexing of the first type of UCI on the TBoMS may also be to start multiplexing the first type of UCI at the first transmission opportunity of the TBoMS.

If the method of multiplexing the first type of UCI on the TBoMS is to multiplex the first type of UCI on the N transmission occasions corresponding to the overlapping parts of the PUCCH carrying the first type of UCI and the TBoMS, the number of time-frequency resources of the TBoMS is the same as before The method in the text is obtained. That is, according to the frequency domain resource position, coding and modulation method, the number of layers during MIMO transmission, the number of uplink symbols in overlapping transmission opportunities, and the number of overlapping transmission opportunities N between PUCCH and TBoMS in the transmission parameters of TBoMS, determine the corresponding TBoMS. The number of time-frequency resources.

According to the comparison result of the number of time-frequency resources of TBoMS and the number of time-frequency resources of the first type of UCI, there may be two cases of transmitting PUCCH or TBoMS.

Case 1, when the number of time-frequency resources of TBoMS is greater than or equal to the number of time-frequency resources of the first type of UCI, the first type of UCI can pass rate matching at the transmission opportunity corresponding to the overlapping part of the PUCCH and TBoMS carrying the first type of UCI. The first type of UCI is multiplexed, and TBoMS is sent.

It should be understood that the PUCCH carrying the first type of UCI may be a PUCCH after multiplexing of multiple PUCCHs, which is not limited in this embodiment of the present application.

For example, FIG. 7 is a schematic diagram of a multiplexing scheme for the first type of UCI on the first PUSCH provided by an embodiment of the present application. In FIG. 7 , the transmission opportunity is taken as an example, and the subcarrier spacing of TBoMS and PUCCH are the same.

The terminal device receives the DCI scheduling PUCCH in the first downlink time slot, and receives the DCI scheduling TBoMS in the second downlink time slot, where TBoMS is scheduled for transmission in 4 uplink time slots, and PUCCH is scheduled in the first TBoMS. 2 uplink time slots for transmission. That is, the PUCCH and TBoMS carrying the first type of UCI overlap on the second uplink time slot, as shown in (a) of FIG. 7 .

The terminal equipment can multiplex the first type through rate matching on the overlapping timeslot of the PUCCH and TBoMS carrying the first type of UCI, that is, as shown in (b) of Figure 7, on the second uplink timeslot of the TBoMS. UCI. A specific implementation manner is that, according to the type of UCI, the above formulas (1) to (9) are selected to realize multiplexing of the first type of UCI.

For example, if the first type of UCI includes HARQ feedback information, CSI part 1 and CSI part 2, when performing rate matching, formulas (1), (4) and (5) are used to calculate the difference in the first type of UCI. The number of coded modulation symbols in each layer corresponding to the type UCI, and then determine the rate matching output sequence length of different code blocks according to the number of coded modulation symbols in each layer, and the output bit sequence after rate matching, and then cascade the rate matching of different code blocks in sequence The output sequence is multiplexed onto the PUSCH. The mapping rules of the first type of UCI on PUSCH have different mapping orders according to the bit size of the HARQ feedback information. Specifically, when the bit size of the HARQ feedback information is greater than 2 bits, the mapping rules shown in Figure 2 are used. When the bit size of the HARQ feedback information is less than or equal to 2 bits, the mapping rule shown in FIG. 4 is used. The above steps realize multiplexing of the first type of UCI on the transmission opportunity corresponding to the overlapping portion of the PUCCH and TBoMS carrying the first type of UCI.

In case 2, when the number of time-frequency resources of TBoMS is less than the number of time-frequency resources of the first type of UCI, the terminal device sends PUCCH at the transmission opportunity corresponding to the overlapping part of TBoMS and PUCCH, and does not send TBoMS; or corresponds to the overlapping part of TBoMS and PUCCH. The TBoMS is still sent on the transmission occasion of the TBoMS, and the PUCCH is canceled.

The terminal device sends PUCCH at the transmission opportunity corresponding to the overlapping part of TBoMS and PUCCH, but does not send TBoMS, which can be understood as sending PUCCH at the transmission opportunity corresponding to the overlapping part of TBoMS and PUCCH, and transmitting the non-TBoMS and PUCCH corresponding to the overlapping part. The TBoMS is sent on the occasion. At this time, the corresponding transmission occasion of the TBoMS is actually sending M transmission occasions, and M is a positive integer less than K, that is, the terminal device sends the TBoMS on the M transmission occasions, and sends the PUCCH on the K-M transmission occasions.

In the solution of the present application, when the non-duplicated PUCCH and TBoMS of the same priority overlap, the UCI carried on the PUCCH is the first type of UCI. By comparing the number of time-frequency resources of TBoMS and the number of time-frequency resources of the first type of UCI If the number of time-frequency resources of TBoMS is greater than or equal to the number of time-frequency resources of the first type of UCI, the first type of UCI is multiplexed on the TBoMS by rate matching, which can effectively take into account the transmission performance of UCI and uplink data. If the number of time-frequency resources of TBoMS is less than the number of time-frequency resources of the first type of UCI, it is possible to flexibly choose to ensure the transmission performance of UCI or ensure the transmission performance of uplink data.

If the first type of UCI starts to be multiplexed at the first transmission opportunity of the TBoMS, the number of time-frequency resources of the TBoMS is obtained through the foregoing method 2. That is, according to the frequency domain resource location, coding and modulation method, the number of layers during MIMO transmission, the number of uplink symbols in overlapping transmission opportunities, and the number of transmission opportunities K of TBoMS in the transmission parameters of TBoMS, determine the time corresponding to TBoMS. number of frequency resources.

Case 1: When the number of time-frequency resources of TBoMS is greater than or equal to the number of time-frequency resources of the first type of UCI, the first type of UCI can be multiplexed from the first transmission opportunity of the first PUSCH through rate matching. UCI.

As a possible implementation method, the terminal device multiplexes the first type of UCI from the first transmission opportunity where the TBoMS is located according to the number of time-frequency resources of the first type of UCI actually calculated, where the first transmission opportunity may be the TBoMS The first transmission opportunity during actual transmission may also be the first transmission opportunity on the TBoMS configured by the access network device for the terminal device, which is not limited in this embodiment of the present application. For example, the terminal device may multiplex the first type of UCI only on the first transmission occasion, or may also multiplex the first type of UCI on the first Z transmission occasions, where Z is a positive integer less than or equal to K; Alternatively, the UCI of the first type may also be multiplexed on K transmission occasions; or, the UCI of the first type may also be multiplexed on the transmission occasions actually transmitted among the K transmission occasions. This embodiment of the present application does not limit this.

For example, FIG. 8 is a schematic diagram of another first-type UCI multiplexing scheme on the first PUSCH provided by an embodiment of the present application. In FIG. 8 , the transmission opportunity is taken as an example, and the subcarrier spacing of TBoMS and PUCCH are the same.

The terminal equipment receives the DCI scheduling the first PUCCH on the first downlink time slot, receives the DCI scheduling the second PUCCH on the second downlink time slot, and receives the DCI scheduling TBoMS on the first special time slot . Among them, TBoMS is scheduled for transmission on 4 uplink time slots, the first PUCCH is scheduled for transmission on the second uplink time slot, and the second PUCCH is scheduled for transmission on the third uplink time slot. The first type of UCI is carried on both the PUCCH and the second PUCCH. That is, the first PUCCH and TBoMS carrying the first type of UCI overlap on the second uplink timeslot, and the second PUCCH and TBoMS carrying the first type of UCI overlap on the third uplink timeslot, as shown in Figure 8 (a).

The terminal equipment multiplexes the first type of UCI from the first time slot of the TBoMS through rate matching according to the number of time-frequency resources of the first type of UCI actually calculated. For example, as shown in (b) of FIG. 8 , the first type of UCI is multiplexed in the first uplink time slot and the second uplink time slot of the TBoMS.

The first type of UCI is multiplexed from the first time slot of TBoMS. For the same type of UCI in the first type of UCI, either joint coding or independent coding can be performed. When joint coding is performed, the number of coded modulation symbols is calculated. The number of bits needs to be added up. The same type of UCI in the first type of UCI can be understood as, the first PUCCH and the second PUCCH both carry the first type of UCI, and the UCIs in these two PUCCHs belong to the first type, but the UCI carried in different PUCCHs are specific. The types can be the same or different. For example, the first type of UCI carried in the first PUCCH has HARQ feedback information, and the first type of UCI carried in the second PUCCH also has HARQ feedback information. Such UCI can be understood It is the same type of UCI in the first type of UCI.

As a possible way of implementation, if the first type of UCI includes HARQ feedback information and CSI, the HARQ feedback information is mapped from ₁₀ of each time slot, that is, from the first one after the DMRS symbol of each time slot Symbol starts mapping; CSI starts mapping from the first symbol that does not carry DMRS in each time slot, and the above formulas (1) to (9) can be selected according to the type of UCI to realize the multiplexing of the first type of UCI. The specific implementation is the same as that in the foregoing description, and the method for realizing the multiplexing of the first type of UCI in (b) of FIG. 7 is the same, and in order to avoid repetition, it is not repeated here.

As another possible implementation, if the first type of UCI includes HARQ feedback information and CSI, the HARQ feedback information is mapped from ₁₀ of the first slot, that is, after the DMRS symbol of the first slot. The first symbol is mapped; CSI is mapped from the first symbol that does not carry DMRS in the first slot, and the rate matching formula needs to be transformed as follows.

If there are both the first type of UCI and UL-SCH in the transmission of TBoMS, where the first type of UCI includes HARQ feedback information and CSI information, the coded modulation symbols of each layer used for the transmission of HARQ feedback information are as shown in formula (10). Show.

The difference between Equation (1) and Equation (10) is that the second part of Equation (10) is the upper limit ratio α of coded modulation symbols mapped to each time slot on TBoMS according to UCI, that is, the scaling parameter α, and the corresponding TBoMS The number of time slots, K, determines the upper limit of the coded modulation symbols of the HARQ feedback information, where,

is the total number of resource elements that can be used to transmit HARQ-ACK on TBoMS, where ₁₀ is the symbol index of the first symbol that does not carry the first DMRS after the symbol of the first DMRS; in addition,

It is defined as the number of OFDM symbols transmitted by TBoMS, that is, the total number of OFDM symbols on K transmission opportunities.

If the first type of UCI includes CG-UCI and CSI information, each layer of coded modulation symbols used for CG-UCI transmission is shown in equation (11).

The difference between the formula (11) and the formula (2) is the same as the difference between the formula (10) and the formula (1), and to avoid repetition, it is not repeated here.

If the first type of UCI includes HARQ feedback information, CG-UCI and CSI information, each layer of coded modulation symbols used for HARQ feedback information transmission is shown in formula (12).

The difference between the formula (12) and the formula (3) is the same as the difference between the formula (10) and the formula (1), and in order to avoid repetition, it is not repeated here.

If there is only the first type of UCI and no UL-SCH in the transmission of TBoMS, where the first type of UCI includes HARQ feedback information and CSI information, the coded modulation symbols of each layer used for the transmission of HARQ feedback information are as shown in Equation (13). Show.

The difference between the formula (13) and the formula (6) is the same as the difference between the formula (10) and the formula (1), and in order to avoid repetition, it is not repeated here.

The CSI information consists of CSI part 1 and CSI part 2. The number of coded modulation symbols in each layer of CSI part 1 is calculated by formula (7), and the number of coded modulation symbols in each layer of CSI part 2 is calculated by formula (8). If it is determined that there is no CSI part 2, the number of coded modulation symbols per layer of CSI part 1 is calculated by formula (9).

The terminal device maps different types of UCIs in the first type of UCIs according to the above formula, starting from the first time slot of the TBoMS until the first type of UCIs are mapped. For the mapping rules of the first type of UCI on TBoMS, refer to the mapping rules of UCI and UL-SCH on PUSCH in FIG. 2 to FIG. 4 .

In case 2, when the number of time-frequency resources of TBoMS is less than the number of time-frequency resources of the first type of UCI, the terminal device sends PUCCH at the transmission opportunity where PUCCH is located, and does not send TBoMS at the transmission opportunity where TBoMS is located; or The TBoMS is sent at the transmission opportunity, that is, a PUSCH transmission block is transmitted in K time slots, and the transmission of the PUCCH is canceled.

FIG. 9 and FIG. 10 show the scheme of multiplexing the second type of UCI on the TBoMS when the PUCCH and TBoMS carrying the second type of UCI overlap.

When the PUCCH and TBoMS carrying the second type of UCI overlap on N transmission occasions in the time domain, the second type of UCI can be multiplexed on the TBoMS, or the transmission of the PUCCH or the transmission of the TBoMS can be cancelled, where N is a positive integer.

As a possible implementation method, the multiplexing of the second type of UCI on the TBoMS may be that the second type of UCI may puncture the transmission opportunities corresponding to the overlapping parts of the TBoMS and the PUCCH, that is, on the N overlapping transmission opportunities of the TBoMS and the PUCCH. Punch holes, N is a positive integer.

It should be understood that the second type of UCI punctures the transmission opportunities corresponding to the overlapping parts of TBoMS and PUCCH, and the second type of UCI covers the original UL-SCH on the N transmission occasions corresponding to the overlapping part according to the number of bits of the second type of UCI. The reason why the UCI of the second type is punctured on the transmission opportunity corresponding to the overlapping part of TBoMS and PUCCH is that the terminal device does not have enough time to map the UCI of the second type and the UL-SCH on the transmission opportunity corresponding to the overlapping part through rate matching.

As a possible implementation manner, the terminal device defines the time condition for puncturing according to the position of the scheduled transmission opportunity of the PUCCH, the processing time of the terminal device, and the start symbol position of the transmission opportunity corresponding to the overlapped part. When the second type of UCI is punctured at the transmission opportunity corresponding to the overlapping portion of TBoMS and PUCCH, it needs to meet the defined puncturing time condition.

As a possible implementation manner, the number of time-frequency resources of the TBoMS is obtained through the foregoing method 1. That is, according to the frequency domain resource position, coding and modulation method, the number of layers during MIMO transmission, the number of uplink symbols in overlapping transmission opportunities, and the number of overlapping transmission opportunities N between PUCCH and TBoMS in the transmission parameters of TBoMS, determine the corresponding TBoMS. The number of time-frequency resources.

According to the comparison result of the number of time-frequency resources of TBoMS and the number of time-frequency resources of the second type of UCI, there may be two cases of transmitting PUCCH or TBoMS.

Case 1, when the number of time-frequency resources of TBoMS is greater than or equal to the number of time-frequency resources of the second type of UCI, the second type of UCI may puncture the transmission opportunity corresponding to the overlapping portion of the PUCCH and TBoMS carrying the second type of UCI.

For example, FIG. 9 is a schematic diagram of a multiplexing scheme of the second type of UCI on the first PUSCH provided by an embodiment of the present application. In FIG. 9 , the transmission opportunity is taken as an example, and the subcarrier spacing of TBoMS and PUCCH are the same.

The terminal equipment receives the DCI for scheduling TBoMS in the third downlink time slot, and receives the DCI for scheduling PUCCH in the second downlink time slot, where TBoMS is scheduled for transmission in 4 uplink time slots, and PUCCH is scheduled in the third time slot of TBoMS. transmitted on upstream time slots. That is, the PUCCH and TBoMS carrying the first type of UCI overlap on the third uplink time slot, as shown in (a) of FIG. 9 .

The terminal equipment can puncture the second type of UCI on the overlapping time slot of the PUCCH carrying the second type of UCI and the TBoMS, that is, the second type of UCI is punctured in the third uplink time slot of the TBoMS, as shown in Figure 9 ( b), the TBoMS is sent.

For example, FIG. 10 is a schematic diagram of another second-type UCI multiplexing scheme on the first PUSCH provided by the embodiment of the present application. In FIG. 10, the transmission opportunity is taken as an example, and the subcarrier intervals of TBoMS and PUCCH are different. The subcarrier spacing of PUCCH is twice the subcarrier spacing of PUCCH, and the duration of one slot of PUCCH is twice the duration of one slot of TBoMS.

The terminal equipment receives the DCI scheduling TBoMS in the second downlink time slot, and receives the DCI scheduling PUCCH in the third downlink time slot. Among them, TBoMS is scheduled to be transmitted on 4 uplink time slots, and PUCCH is scheduled to be transmitted on the 3rd and 4th uplink time slots of TBoMS. That is, the PUCCH and TBoMS carrying the first type of UCI overlap on the third and fourth uplink time slots of TBoMS, as shown in (a) of FIG. 10 .

As a possible implementation, the terminal device sends PUCCH on the time slot corresponding to the overlapping part of TBoMS and PUCCH, but does not send TBoMS. As shown in (b) of Figure 10, the third and fourth overlapping TBoMS and PUCCH The PUCCH is transmitted on the 3rd and 4th uplink timeslots, and the TBoMS is not transmitted on the 3rd and 4th uplink timeslots, and only part of the TBoMS is transmitted on the 1st and 2nd uplink timeslots.

As another possible implementation, the terminal device still sends TBoMS on the time slot corresponding to the overlapping part of TBoMS and PUCCH, but does not send PUCCH, as shown in (c) of FIG. 10, when the first to fourth uplink Send TBoMS on the slot, cancel the transmission of the PUCCH that originally needs to be transmitted on the 3rd and 4th uplink time slots.

In the solution of the present application, when non-duplicated PUCCH and TBoMS of the same priority overlap, the UCI carried on the PUCCH is the second type of UCI. By comparing the number of time-frequency resources of TBoMS and the number of time-frequency resources of the second type of UCI If the number of time-frequency resources of TBoMS is greater than or equal to the number of time-frequency resources of the second type of UCI, and the second type of UCI is punctured at the transmission opportunity corresponding to the overlapping part of the PUCCH and TBoMS carrying the second type of UCI, you can Allows the terminal device to effectively take into account the transmission performance of UCI and uplink data in the limited processing time. If the number of time-frequency resources of TBoMS is less than the number of time-frequency resources of the first type of UCI, it can flexibly choose to guarantee the transmission performance of UCI or guarantee the uplink. data transfer performance.

FIG. 11 to FIG. 13 show transmission schemes of PUCCH and TBoMS when the PUCCH carrying the second type of UCI and the PUCCH carrying the first type of UCI and TBoMS overlap.

FIG. 11 shows a possible solution for a terminal device to transmit PUCCH or TBoMS when the PUCCH carrying the first type of UCI and the PUCCH carrying the second type of UCI are not scheduled on the same transmission occasion.

The terminal equipment does not expect the PUCCH carrying the UCI of the second type, and is scheduled at the transmission timing of the PUCCH carrying the UCI of the first type, that is, the access network equipment will not send the PUCCH carrying the UCI of the second type and the PUCCH carrying the UCI of the first type to the terminal equipment. Scheduling information for UCI-like PUCCH scheduling on the same transmission occasion. The terminal equipment will not allow the second type of UCI to puncture the transmission opportunity corresponding to the first type of UCI that has been multiplexed through rate matching.

As a possible implementation manner, the terminal device may transmit the TBoMS and/or the PUCCH through the foregoing scheme for the first type of UCI multiplexing on the TBoMS, which is not repeated here in order to avoid repetition. The terminal device can transmit TBoMS and/or PUCCH through the scheme of multiplexing the second type of UCI on the TBoMS. To avoid repetition, it will not be repeated here. The second type of UCI cannot be multiplexed with the transmission of the first type of UCI. Punch holes in time.

For example, FIG. 11 is a schematic diagram of a multiplexing scheme of the first type of UCI and the second type of UCI on the first PUSCH provided by the embodiment of the present application. The interval is the same.

The terminal device receives and schedules the DCI of the PUCCH carrying the first type of UCI in the first downlink time slot, and the PUCCH carrying the first type of UCI is the first PUCCH in (a) of FIG. Receive the DCI scheduling the PUCCH carrying the second type of UCI, the PUCCH carrying the second type UCI is the second PUCCH in FIG. 11( a ), and receive the DCI scheduling the TBoMS in the first downlink time slot. Among them, TBoMS is scheduled to be transmitted on 4 uplink time slots, and the first PUCCH is scheduled to be transmitted on the first uplink time slot of TBoMS. That is, the PUCCH carrying the first type of UCI overlaps with the TBoMS on the first uplink time slot; the second PUCCH is scheduled to be transmitted on the third uplink time slot of the TBoMS. That is, the PUCCH and TBoMS carrying the second type of UCI overlap on the third uplink time slot, as shown in (a) of FIG. 11 . The access network device does not schedule the PUCCH carrying the UCI of the second type and the PUCCH carrying the UCI of the first type on the same transmission occasion.

The terminal equipment can multiplex the first type of UCI through rate matching on the overlapping time slot of the PUCCH carrying the first type of UCI and the TBoMS, that is, on the first uplink time slot of the TBoMS, as shown in (b) of Figure 11. Show. The terminal equipment can puncture the second type of UCI on the overlapping time slot of the PUCCH and TBoMS carrying the second type of UCI, that is, on the third uplink time slot of TBoMS, as shown in (b) of Figure 11, send TBoMS. It should be understood that the multiplexing manner of the first type of UCI and the second type of UCI on TBoMS shown in (b) of FIG. 11 is only an example.

In the solution of the present application, the terminal device does not expect the PUCCH carrying the second type of UCI, and schedules the PUCCH carrying the first type of UCI at the transmission opportunity, which can prevent the second type of UCI from puncturing the first type of UCI and reduce the occupation at the same time. The number of symbols of the UL-SCH, that is, to ensure the transmission performance of the first type of UCI and the UL-SCH.

FIG. 12 and FIG. 13 show possible solutions for the terminal equipment to transmit PUCCH or TBoMS when the PUCCH carrying the first type of UCI and the PUCCH carrying the second type of UCI are scheduled on the same transmission occasion

When the PUCCH and TBoMS carrying the first type of UCI overlap on N transmission occasions in the time domain, the PUCCH and TBoMS of the second type of UCI overlap on the N transmission occasions in the time domain, and the PUCCH and TBoMS carrying the first type of UCI overlap. The PUCCHs carrying the second type of UCI overlap on the same transmission occasion. If the number of time-frequency resources of the TBoMS is greater than the number of time-frequency resources of the first type of UCI and the second type of UCI, the terminal device can determine the transmission mode of the first type of UCI and the second type of UCI.

As a possible implementation manner, the terminal device may first perform rate matching to multiplex the first type of UCI on the TBoMS, and then puncture the second type of UCI after the number of time-frequency resources corresponding to the first type of UCI.

For example, FIG. 12 is a schematic diagram of another scheme of multiplexing the first type of UCI and the second type of UCI on the first PUSCH in the embodiment of the present application. In FIG. 12 , the transmission opportunity is taken as the time slot as an example. The interval is the same.

The terminal device receives and schedules the DCI of the PUCCH carrying the first type of UCI in the first downlink time slot, and the PUCCH carrying the first type of UCI is the first PUCCH in (a) of FIG. Receive the DCI scheduling the PUCCH carrying the second type of UCI, the PUCCH carrying the second type UCI is the second PUCCH in FIG. 12(a), and receive the DCI scheduling TBoMS in the second downlink time slot. Among them, TBoMS is scheduled for transmission on 4 uplink time slots, the first PUCCH is scheduled for transmission on the third uplink time slot of TBoMS, and the second PUCCH is also scheduled for transmission on the third uplink time slot of TBoMS . That is, the PUCCH carrying the first type of UCI, the PUCCH carrying the second type of UCI and the TBoMS overlap on the same time slot, that is, on the third uplink time slot, as shown in (a) of FIG. 12 . The access network device schedules the PUCCH carrying the second type of UCI and the PUCCH carrying the first type of UCI on the same transmission occasion.

The terminal equipment can multiplex the first type of UCI through rate matching on the overlapping time slot of the PUCCH and TBoMS carrying the first type of UCI, that is, on the third uplink time slot of the TBoMS, and the second type of UCI in the fourth Punch holes in the uplink time slot, as shown in (b) of FIG. 12 .

As another possible implementation, the terminal device can first use rate matching to multiplex the first type of UCI on the TBoMS, and then put the second type of UCI on the resource unit corresponding to the HARQ feedback information in the first type of UCI except for the HARQ feedback information. hole.

The fact that the second type of UCI is punctured in the resource units corresponding to the HARQ feedback information can be understood as the fact that the second type of UCI can be punctured in the resource units corresponding to the first type of UCI, but cannot be used for HARQ feedback in the first type of UCI. Punch holes in the time-frequency resources corresponding to the information.

As a possible implementation manner, for example, as shown in FIG. 13 , the terminal device may puncture the time-frequency resources corresponding to the UL-SCH. A schematic diagram of the multiplexing scheme of the second type of UCI on the first PUSCH. In FIG. 13 , the transmission opportunity is taken as an example, and the subcarrier spacing of TBoMS and PUCCH are the same.

The scheduling situation received by the terminal device is the same as that of FIG. 12(a), that is, FIG. 13(a) is the same as FIG. 12(a).

The terminal equipment can multiplex the first type of UCI through rate matching on the overlapping time slot of the PUCCH carrying the first type of UCI and the TBoMS, that is, on the third uplink time slot of the TBoMS, and the second type of UCI in the first type of UCI. Punch holes in the time slot where the UCI is located, but skip the number of time-frequency resources corresponding to the first type of UCI, and directly punch the number of time-frequency resources corresponding to the UL-SCH on the third uplink time slot, as shown in Figure 13 ( b) shown.

As a possible implementation manner, the second type of UCI may also puncture the number of time-frequency resources corresponding to the UL-SCH and CSI part 2 in the transmission occasion where the first type of UCI is located.

As a possible implementation manner, the second type of UCI may also puncture the number of time-frequency resources corresponding to the UL-SCH and CSI in the transmission occasion where the first type of UCI is located.

As a possible implementation manner, the second type of UCI may also start puncturing forward at the last symbol in the transmission occasion where the first type of UCI is located. For example, the puncturing starts from the 14th symbol from the back to the front, or the puncturing starts from the first symbol after the last group of consecutive symbols carrying DMRS.

As a possible implementation method, if the bit of the HARQ feedback information is 0 and there is no CG-UCI, as shown in Figure 4, the terminal device reserves resources for the HARQ feedback information, and the second type of UCI can be reserved first. Punch holes on the number of time-frequency resources.

According to the solution of the present application, when the non-repetitive PUCCH carrying the first type of UCI, the non-repetitive PUCCH carrying the second type UCI and the TBoMS of the same priority overlap at the same transmission timing, the first type of UCI and the second type of UCI are overlapped. UCI satisfies different conditions, and according to the number of time-frequency resources of the first type of UCI and the second type of UCI and the number of time-frequency resources of TBoMS, the first type of UCI is multiplexed on TBoMS through rate matching, and the second type of UCI is multiplexed on TBoMS through rate matching. UCI punches holes at appropriate positions on TBoMS, and the second type of UCI punches holes on TBoMS, which avoids affecting the transmission of the first type of UCI to a large extent. Therefore, the solution of the present application can simultaneously guarantee the first type of UCI to a certain extent. Transmission performance of UCI and Type II UCI over TBoMS.

As a possible implementation manner, the terminal device does not expect that the DCI for scheduling the PUCCH indicates the PUCCH, and the DCI for scheduling the first PUSCH indicates the PUSCH to overlap in the time domain. When the DCI scheduling the PUCCH or the DCI scheduling the first PUSCH indicates that the PUCCH and the first PUSCH do not overlap in the time domain, the terminal device determines that the UCI carried on the PUCCH is not multiplexed for transmission on the first PUSCH, and the terminal device sends the PUCCH and First PUSCH.

As a possible implementation manner, the transmission parameters of the first PUSCH may be carried in the physical layer indication DCI, or in other messages that can transmit the transmission parameters of the first PUSCH, which are not limited in this embodiment of the present application.

As a possible implementation manner, the physical layer indicates that the DCI can also carry the transmission parameters of aperiodic CSI, wherein the transmission parameters of the aperiodic CSI and the transmission parameters of the first PUSCH are carried in the same message, and the transmission parameters of the aperiodic CSI are carried in the same message. It is used to indicate that the terminal equipment is multiplexed with aperiodic CSI on the first PUSCH.

As a possible implementation manner, the terminal device does not expect the physical layer indicating the DCI carrying the transmission parameters of the first PUSCH, and simultaneously carries the transmission parameters of the aperiodic CSI. That is, the access network device will not send the DCI that simultaneously carries the transmission parameters of the first PUSCH and the aperiodic CSI to the terminal device.

The transmission parameters of TBoMS may include at least one of the following parameters: frequency domain resource location, subcarrier spacing configuration μ, coding and modulation method, number of layers during MIMO transmission, scaling parameter α, code rate offset factor β _offset , TBoMS priority level index and number K of TBoMS transmission occasions. It should be understood that these parameters are the transmission parameters of the TBoMS involved in the embodiments of the present application, not all the transmission parameters of the TBoMS.

The terminal device may determine the subcarrier spacing Δf=2 ^μ ·15 [kHz] of TBoMS according to the subcarrier spacing configuration μ.

The terminal device may determine that a PUSCH transmission block is to be transmitted on K transmission occasions according to the number K of continuous transmission occasions for TBoMS transmission, and the transmission occasions may include time slots or transmission occasions.

Wherein, the transmission opportunity may include one or more time slots, and may also include one time slot or part of symbols in multiple time slots. For example, one transmission opportunity may include the third symbol to the twelfth symbol. The number of symbols included in the timing and the symbol positions are not limited.

Among them, the first PUSCH has only one transport block TB CRC attached on K transmission occasions, which can be understood as the first PUSCH only transmits one PUSCH transport block on K transmission occasions, and there is only one PUSCH Transport block CRC is attached.

S1402, the terminal device sends the first PUSCH according to the transmission parameter of the first PUSCH, wherein the first PUSCH multiplexes the aperiodic channel state information CSI.
