The embodiment of the application can be suitable for downlink signal transmission, can also be suitable for uplink signal transmission, and can also be suitable for device-to-device (D2D) signal transmission. For downlink signal transmission, the sending device is a radio access network device, and the corresponding receiving device is a terminal device.

The following briefly introduces several basic concepts in the NR standard to which embodiments of the present application relate.

The present embodiment relates to the following basic concepts in the time domain.

The symbol is the smallest time unit in the time domain structure, for example, in NR, the symbol may be an (orthogonal frequency-division multiplexing, OFDM) symbol, and may also be a discrete fourier transform-orthogonal frequency-division multiplexing (DFT-s-OFDM) symbol.

A slot (slot) is a unit of time in a time domain structure, and 1 slot may be equal to 12 symbols, or 1 slot may be equal to 14 symbols. In the embodiment of the present application, the number of symbols that can be included in 1 slot is not limited, and only one slot is taken as an example, which is equal to 14 symbols.

A subframe (subframe) is a unit of time in a time domain structure, each subframe lasts for 1ms, and each subframe may be divided into several slots. The correspondence of each subframe and slot is determined by a parameter set, for example, 1 subframe equals 1 slot when subcarrier spacing (SCS) is 15kHz, and 1 subframe equals 2 slots when SCS is 30 kHz.

NR supports a time slot for uplink transmission, and the time slot is marked as a U time slot; one time slot is also supported for downlink transmission, and the time slot is marked as a D time slot; one timeslot is also supported to perform uplink transmission or downlink transmission, which is called a special timeslot, and the timeslot is denoted as an S timeslot, that is, the timeslot can be selected for uplink transmission or downlink transmission according to actual situations. Similarly, for a special time slot, an S-slot, the time slot may include an uplink symbol and a downlink symbol, or an uplink symbol and a flexible symbol, or a downlink symbol and a flexible symbol, or an uplink symbol, a downlink symbol, and a flexible symbol, where the uplink symbol is used for uplink transmission, the downlink symbol is used for downlink transmission, and the flexible symbol may 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, dddddddddduu, or the like.

The embodiment of the application relates to the concept on the frequency domain: the subcarrier (subcarrier) is the smallest frequency domain unit in the frequency domain structure.

A Resource Block (RB) is 12 consecutive subcarriers over 1 slot.

Physical Resource Blocks (PRBs) are used to indicate the relative position of a resource block in an actual transmission.

The embodiment of the present application relates to the following basic concepts on time-frequency resources.

A Resource Element (RE) is the smallest physical element in the NR standard, and 1 RE is 1 subcarrier on 1 OFDM symbol.

The 1 RB in NR is a fixed set of 12 subcarriers, but since there are different subcarrier spacings in NR, the actual bandwidth occupied by RBs corresponding to different subcarrier spacings in the frequency domain is different.

The uplink transmission in NR involves the following basic concepts.

The uplink channel in NR includes: a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), and a Physical Random Access Channel (PRACH).

The uplink signal in NR includes: the mobile terminal includes a Sounding Reference Signal (SRS), a demodulation reference signal (DMRS), and a phase-tracking reference signal (PTRS), where an uplink DMRS is carried on a PUCCH or a PUSCH and transmitted, occupies a part of resources of the PUCCH or the PUSCH, and an uplink PTRS is carried on a PUSCH and transmitted, and occupies a part of resources of the PUSCH.

The PUCCH is used to carry UCI. The PUCCH has 5 formats, namely PUCCH format 0/1/2/3/4. The UCI bit number carried by the PUCCH format 0/1 is less than or equal to 2 bits; the UCI bit number carried by the PUCCH format 2/3/4 is more than 2 bits.

In a time domain, the duration length of PUCCH format 0/2 is 1-2 OFDM symbols, which are called short PUCCH, and the short PUCCH can not be repeated; and the continuous length of the PUCCH format 1/3/4 is 4-14 OFDM symbols, which are called long PUCCH, the long PUCCH can be repeated in the time domain, and the repetition time can be 2/4/8 times.

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

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

The transmission scheme of PUSCH in NR involves the following.

First, PUSCH transmission based on dynamic scheduling: on a per PUSCH transmission basis, scheduling is performed using Downlink Control Information (DCI) indicated by a physical layer. That is, the terminal device performs PUSCH transmission once when receiving uplink scheduling of DCI once.

Second, PUSCH transmission based on Configuration Grant (CG) type 1: the terminal equipment receives high-level configuration (high-level parameter configurable GrantConfig containing rrc-configurable uplink Grant), does not receive physical layer indication DCI, and configures some semi-continuous time frequency resources at the high level, and if the terminal equipment has uplink data to be sent, the terminal equipment sends the PUSCH on the semi-continuous time frequency resources configured at the high level; and if no uplink data needs to be sent, not sending the data.

Third, PUSCH transmission based on configured grant type 2: the terminal device receives a higher layer configuration (higher layer parameter config _ grant config not containing rrc-configurable uplink grant, that is, the higher layer configuration received by the terminal device has no configuration parameter rrc-configurable uplink grant), the terminal device selects the semi-persistent time-frequency resources of the higher layer configuration for use, and the semi-persistent time-frequency resources are activated or deactivated by DCI. If the DCI indication is activated, the terminal equipment uses semi-continuous time frequency resources according to the requirement of transmitting data per se, specifically a second PUSCH transmission mode; these semi-persistent time-frequency resources cannot be used if the DCI indicates deactivation.

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

Hybrid automatic repeat request acknowledgement (HARQ-ACK) includes Acknowledgement (ACK) or Negative Acknowledgement (NACK). The UE may multiplex the HARQ-ACK information on the PUSCH.

The Channel State Information (CSI) specifically includes a Precoding Matrix Indicator (PMI), a Rank Indicator (RI), a Layer Indicator (LI), channel Quality Information (CQI), a CSI-RS (RS) resource indicator (CRI), a Reference Signal Received Power (RSRP), and the like. The CSI may be divided into a channel state information first-part CSI part 1 and a channel state information second-part CSI part 2. The CSI part 1 may include CRI, RI, wideband CSI of the first TB, sub-band differential CQI of the first TB, and the like; the CSI part 1 may include wideband CQI, LI, etc. of the second TB. The embodiments of the present application do not limit which CSI part 1 and CSI part2 specifically include which CSI. When the CSI report on PUSCH includes two parts, the terminal device may omit a part of CSI part 2. When CSI reports are transmitted on PUCCH, the terminal device may ignore a portion of CSI part2 if any of the CSI reports consists of two parts. The CSI reports may be periodic, semi-persistent, or aperiodic (aperiodic). An Aperiodic Channel State Information (ACSI) report may be triggered to be sent on the PUSCH; if the PUSCH contains uplink data, the UE multiplexes the ACSI report on the PUSCH.

Scheduling Request (SR). The UE does not multiplex the SR on the PUSCH.

Currently, when a terminal device sends PUCCHs and/or PUSCHs to a radio access network device, overlapping may occur. That is, PUCCHs and puschhs overlap, or multiple PUCCHs overlap, or multiple PUSCHs overlap. The overlapping of PUCCHs and PUSCHs means that PUCCHs and PUSCHs overlap in a time domain, and similarly, the overlapping meaning of multiple PUCCHs and multiple PUSCHs is similar to the overlapping meaning of PUCCHs and PUSCHs, and for the sake of brief description, the description is omitted here.

PUCCH and PUSCH may be assigned different priority indexes. Where priority index 0 represents a smaller priority index, which may also be referred to as a low priority index, and priority index 1 represents a larger priority index, which may also be referred to as a high priority index. When the PUCCHs and/or PUSCHs with different priorities are overlapped, the PUCCHs and/or PUSCHs with the transmission priority index of 0 are cancelled under most conditions according to different priority indexes.

When the PUCCHs and/or PUSCHs with the same priority are/is overlapped, three situations exist, namely, a plurality of PUCCHs with the same priority are overlapped, a plurality of PUSCHs with the same priority are overlapped, and a PUCCH and a PUSCH with the same priority are overlapped.

Before describing the concrete processing modes of the three current overlapping cases, a concept is described: time conditions. When the terminal equipment expects the same priority PUCCHs and/or PUSCHs to overlap, the time condition is met. Different transmission modes of the PUSCH and/or PUCCH and different time conditions, for example, the transmission mode of at least one of the PUSCH and/or PUCCH is dynamic scheduling, and the time condition is that sufficient processing time exists between the terminal device receiving the last symbol of the PDCCH or PDSCH corresponding to the dynamic scheduling and the terminal device transmitting the first symbol of the earliest PUSCH and/or PUCCH.

In case 1, if multiple PUCCHs with the same priority are overlapped, different processing modes are available according to whether the PUCCHs are overlapped or not. If the PUCCH has the repetition, the PUCCH to be transmitted is selected according to the priority rule among different types of UCI and the time early-late rule.

In case 2, if the PUCCH is not duplicated and overlaps with multiple PUSCHs with the same priority, the terminal device selects the PUSCH for multiplexing the HARQ feedback information and/or the CSI report according to a certain rule, and the specific rule is as follows, the following rules are in order, and the higher the priority is, the higher the priority is.

Firstly, terminal equipment multiplexes HARQ feedback information on a PUSCH carrying ACSI; secondly, multiplexing HARQ feedback information and/or CSI reports on a PUSCH corresponding to a first time slot in the time slots of the plurality of overlapped PUSCHs by the terminal equipment; thirdly, multiplexing HARQ feedback information and/or CSI report on the PUSCH which is dynamically scheduled; fourthly, multiplexing HARQ feedback information and/or CSI report on the PUSCH of the serving cell with the minimum serving cell index (ServCellIndex) value; fifthly, the earliest PUSCH transmitted by the terminal device in the slot, where the earliest PUSCH can be understood as the PUSCH corresponding to the earliest symbol in the slot.

In case 3, if the PUCCH and PUSCH of the same priority are overlapped, there are different processing modes according to whether the PUCCH has repetition, where the PUCCH has repetition indicating that the PUCCH is repeatedly transmitted in multiple slots, and the same PUCCH is repeatedly transmitted in each slot.

When the PUCCH is repeated, the terminal equipment does not multiplex UCI on the PUSCH, and when the time condition is met, the PUCCH is transmitted on the overlapped time slot, and the PUSCH is not transmitted; or on the actual repetition of the PUSCH, the PUCCH is transmitted and the PUSCH is not transmitted.

When the PUCCH is not repeated, the terminal equipment multiplexes UCI in the overlapped PUCCH, and if the PUSCH does not carry UL-SCH and the PUCCH carries a positive scheduling request, the terminal equipment does not transmit the PUSCH and only transmits the PUCCH; in other cases, the terminal device may multiplex HARQ feedback information and/or CSI reports on the selected PUSCH as needed, and does not transmit the scheduling request, that is, the scheduling request is not multiplexed on the PUSCH, that is, the scheduling request is not carried on the PUSCH.

At present, the process of multiplexing UCI on PUSCH is: firstly, generating a bit sequence according to different UCI types; secondly, according to the bit sequence, code block segmentation and CRC addition are carried out; thirdly, determining a channel coding method according to the bit sequence; fourthly, obtaining the number of the coded modulation symbols of each layer of the UCI of different types through rate matching, and determining the length of a rate matching output sequence of different code blocks and an output bit sequence after rate matching according to the number of the symbols; fifthly, sequentially cascading rate matching output bit sequences of different code blocks; sixthly, the UE multiplexes the concatenated bit sequence on the PUSCH.

The second and third specific steps may be that if the payload number of the UCI bit sequence is less than or equal to 11 bits, the CRC is not attached, and the UCI channel coding mode is determined to be small block long channel coding; if the load number of the UCI bit sequence is more than or equal to 12 bits, attaching CRC, and determining the channel coding mode of the UCI as Polar code.

When Polar codes are used for channel coding, the mode of obtaining the number of coded modulation symbols of each 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, different types of UCI calculate the number of coded modulation symbols of each layer according to the following rate matching rules.

When the UCI information comprises HARQ feedback information and does not comprise configuration permission information CG-UCI, the code modulation symbol number of each layer of the HARQ feedback information is calculated by formula (1), wherein

Indicating rounding up.

Wherein, the physical meaning of the first part of the formula (1) is the actual data bit number (bit number O before coding) according to the HARQ feedback information _ACK And the number L of CRC check bits _ACK ) Code rate offset factor

And the code rate of the uplink data to calculate the number of the resource units after the HARQ feedback information is coded.

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

the physical meaning of (1) is the code rate of the uplink data,

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

The physical meaning of the second part of equation (1) is to determine the upper limit of the number of resource elements of the HARQ feedback information according to the upper limit proportion alpha of the number of resource elements of the UCI mapped on the PUSCH, wherein

Is the total number of resource elements on the PUSCH available for transmission of HARQ-ACK, where l ₀ Is the symbol index of the first symbol after the symbol of the first demodulation reference signal DMRS, which does not carry the DMRS.

The minimum value of the two parts is used as the code modulation symbol number Q 'of each layer for HARQ feedback information transmission' _ACK 。

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

Wherein O is _CG-UCI Number of bits, L, of CG-UCI _CG-UCI The CRC check bit number of CG-UCI.

The CSI information is composed of CSI part 1 and CSI part2, the number of coded modulation symbols of each layer of the CSI part 1 is obtained by calculation of formula (4), and the number of coded modulation symbols of each layer of the CSI part2 is obtained by calculation of formula (5).

Wherein, when the UCI information has HARQ feedback information and has no CG-UCI and the number of bits of the HARQ feedback information is more than 2, Q' _ACK/CG-UCI Is Q 'in formula (1)' _ACK . Q 'if no HARQ feedback information exists in UCI information and CG-UCI exists' _ACK/CG-UCI Is Q 'in formula (2)' _CG-UCI . Q 'when HARQ feedback information and CG-UCI exist in UCI information' _ACK/CG-UCI Is Q 'in formula (3)' _ACK 。

Q 'in the formula (4) when HARQ feedback information exists in the UCI information, no CG-UCI exists, and the bit number of the HARQ feedback information is 0/1/2' _ACK/CG-UCI Is composed of

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

When UCI information is transmitted on the PUSCH but uplink data information is not transmitted, different types of UCI calculate the number of coded modulation symbols of each layer according to the following rate matching rules respectively.

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

Wherein Q is _m Is the modulation order and R is the code rate.

The CSI information comprises CSI part 1 and CSI part2, or CSI part 1, when the UCI information is transmitted on the PUSCH but the uplink data information is not transmitted, if the CSI part2 is determined to exist, the number of coded modulation symbols of each layer of the CSI part 1 is obtained by calculation of a formula (7), and at the moment, the number of coded modulation symbols of each layer of the CSI part2 is obtained by calculation of a formula (8). If it is determined that there is no CSI part2, the number of coded modulation symbols per layer of CSI part 1 is calculated by equation (9).

If the small block long channel coding is used, the coding modulation symbol number of each layer for UCI transmission is calculated by taking a time slot as a unit, and the calculation formula under Polar channel coding corresponds to one. The difference is that the number L of CRC bits of different types of UCI is 0 when small block long channel coding is performed.

The current mapping rule of UCI and UL-SCH multiplexing on PUSCH will be specifically described below with reference to fig. 2, fig. 3 and fig. 4. Fig. 2 is a schematic diagram of a current mapping rule of UCI and UL-SCH multiplexing on PUSCH provided in an embodiment of the present application.

The HARQ feedback information of (a), (b), (c), and (d) of fig. 2 is mapped such that when the HARQ feedback information is more than 2 bits, or when the UCI information includes HARQ feedback information and CG-UCI, then according to an actual size, mapping is sequentially performed starting at the first available symbol after a DMRS symbol. If the HARQ feedback information and the CG-UCI (if any) can fill the current whole symbol, the current symbol is filled and then the next symbol is filled. If the HARQ feedback information and the CG-UCI (if any) are not enough to occupy the current whole symbol, they are equally spaced over the frequency domain resources on the current symbol.

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

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

S203, when the HARQ feedback information is more than 2 bits, or when the UCI information includes HARQ feedback information and CG-UCI, as shown in (c) of fig. 2, sequentially mapping CSI part2 starting from a first available symbol resource on the PUSCH, wherein the first available symbol resource is the first available symbol resource on the PUSCH excluding resource elements to which the DMRS, HARQ feedback information, and CSI part 1 are mapped.

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

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

In fig. 4, the HARQ feedback information (a), (b), (c), (d), and (e) is mapped such that, when the HARQ feedback information has any size of 0,1, or 2 bits and there is no CG-UCI, PUSCH resources are reserved according to 2-bit HARQ feedback information, starting with the first UCI available symbol after the DMRS symbol in the PUSCH, to become a reserved region. 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 units in the figure is only an exemplary function.

S401, reserving the number of resource units to be mapped by the HARQ feedback information in the UCI information, and forming a resource reservation region of the HARQ feedback information, where the resource reservation region starts from the first available symbol after the DMRS symbol, as shown in (a) of fig. 4.

S402, mapping CSI part 1 in UCI information, and when HARQ feedback information is any one of 0,1 or 2 bits, as shown in fig. 4 (b), sequentially mapping CSI part 1 from the first available symbol resource on PUSCH, bypassing HARQ feedback information reserved region, and ensuring that CSI part 1 does not collide with HARQ feedback information. The first available symbol resource is a resource unit except the reserved region of DMRS and HARQ feedback information, and the first available symbol resource on the PUSCH.

S403, mapping CSI part2 in UCI information, and when the HARQ feedback information is any one of 0,1 or 2 bits, as shown in fig. 4 (c), sequentially mapping CSI part2 from a first available symbol resource on the PUSCH, where the first available symbol resource is a resource unit excluding the DMRS and CSI part 1, and the first available symbol resource on the PUSCH does not need to be bypassed at this time.

S404, mapping uplink data information, and when the HARQ feedback information is any one of 0,1 or 2 bits, as shown in (d) of fig. 4, sequentially mapping the uplink data from a first available symbol resource on the PUSCH, where the first available symbol resource is a resource unit excluding the DMRS, CSI part 1 and CSI part2 mappings, and the first available symbol resource on the PUSCH.

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

In most cases, one PUSCH transport block is transmitted on only one slot, and one PUSCH transport block may be transmitted on multiple slots when TBoMS occurs later. In a scenario where uplink coverage is limited, the TBoMS may boost channel coding gain by aggregating smaller packets over multiple timeslots. Besides, the TBoMS can reduce the number of bits occupied by the CRC, thereby saving resources. Because the single TB of the TBoMS is elongated in the time domain, the number of resource blocks or resource units occupied in the frequency domain can be reduced, and the power spectral density is improved.

At present, the processing mode of UCI multiplexing on PUSCH is to transmit a single PUSCH transmission block on one slot, and for TBoMS, under the condition that the size of the transmission block is not changed, a single transmission block needs to be transmitted on multiple slots, resulting in a reduction in the number of available resource units on a single slot, thereby resulting in a reduction in the number of resource units available for UCI when UCI is multiplexed on PUSCH, and if the current processing mode of UCI multiplexing on PUSCH is continuously used, more discarded UCI bits are needed, which will affect transmission of UCI and uplink data, thereby affecting system performance. Therefore, how to make UCI and UL-SCH effectively transmit on TBoMS is an urgent problem to be solved.

Because a single PUSCH transmission block needs multiple time slots for transmission, after a PUCCH and a TBoMS having no repetition at the same priority are overlapped, if the PUCCH carrying UCI does not satisfy the time condition for PUCCH and TBoMS transmission, transmission needs to be performed after TBoMS transmission is finished, which may cause long information delay in UCI and affect system performance.

When a PUCCH and a TBoMS having the same priority are overlapped, at present, a terminal device may multiplex UCI on one transmission opportunity of the TBoMS, but when a time-frequency resource required by the UCI is too large, part of UCI bits may be discarded, transmission performance of the UCI may not be guaranteed, and transmission performance of the UL-SCH may also be affected. The terminal equipment can also directly cancel the transmission of the TBoMS and send the PUCCH, but the scheme sacrifices the transmission of the UL-SCH to ensure the transmission performance of the UCI. The terminal device may also directly puncture UCI originally scheduled to be transmitted on the PUCCH on the TBoMS, but does not consider other UCI multiplexed on the TBoMS, and directly puncture on the TBoMS, which may affect the transmission performance of other UCI. Therefore, the application provides a technical scheme capable of ensuring the transmission performance of UCI and UL-SCH as far as possible.

The present application provides an information transmission method that can ensure transmission performance of UCI and UL-SCH as much as possible, and the method is described below with reference to fig. 5. Fig. 5 is a schematic flow chart of an information sending method according to an embodiment of the present application.

It should be understood that there is no sequence between the steps S501 and S502, that is, S501 and then S502 may be executed first, or both steps may be executed simultaneously. The embodiments of the present application do not limit this.

As a possible implementation manner, the transmission parameter of the first PUSCH may be carried in the DCI indicated by the RRC signaling and/or the physical layer, which is not limited in this embodiment of the present invention.

It is to be understood that the message carrying the transmission parameters of the first PUSCH and the transmission parameters carrying the PUCCH are different messages.

For the sake of brief explanation, in the following description, "TBoMS" represents the first PUSCH, which may also have other names, and this is not limited in this application.

The transmission parameters of the TBoMS may include at least one of the following parameters: frequency domain resource position, subcarrier interval configuration mu, coding modulation mode and MIMO transmissionTime layer number, expansion parameter alpha and code rate offset factor beta _offset TBoMS priority index, and number of transmission occasions K for TBoMS. It should be understood that these parameters are the transmission parameters of the TBoMS referred to in the embodiments of the present application, and not all TBoMS.

The following describes the actions of the transmission parameters of the TBoMS.

The terminal equipment can determine the number of physical resource blocks for sending the TBoMS and the position of each physical resource block according to the position of the frequency domain resource.

The terminal device may determine a subcarrier spacing Δ f =2 of the TBoMS according to the subcarrier spacing configuration μ ^μ ·15[kHz]. It should be understood that the subcarrier interval configuration μ in the transmission parameter of the PUCCH and the subcarrier interval configuration μ in the transmission parameter of the TBoMS may be the same or different, and this is not limited in this embodiment of the present application.

The terminal equipment can determine the modulation mode and the coding rate of TBoMS transmission according to the coding modulation mode.

The terminal equipment can transmit according to the number of layers, the stretching parameter alpha and the code rate offset factor beta when MIMO is transmitted _offset And when the UCI is multiplexed on the TBoMS, determining the number of coded modulation symbols of each layer of different types of UCI.

The terminal device may determine the priority information of the TBoMS according to a TBoMS priority index, where the TBoMS priority index may include a priority index 0 or a priority index 1.

The terminal device may determine that one PUSCH transmission block is transmitted on K transmission occasions according to the number K of transmission occasions of the TBoMS.

For example, a slot may include 14 symbols, a partial symbol in a slot may include 3 rd to 12 th symbols, and when one transmission opportunity is a partial symbol in a slot, the number of symbols included in the transmission opportunity and the position of the symbol are not limited in the embodiments of the present application.

The first PUSCH only includes one transport block TB cyclic redundancy check CRC attachment on K transmission occasions, which can be understood as that the first PUSCH transmits only one PUSCH transport block on K transmission occasions, carries uplink data and/or UCI on the PUSCH, and attaches only one TB CRC. The second PUSCH has K TB CRCs attached at K transmission occasions, that is, the second PUSCH transmits K PUSCH transmission blocks at K transmission occasions, and has K TB CRCs attached, that is, the same PUSCH is repeatedly transmitted K times at K transmission occasions, where K is a positive integer greater than or equal to 2.

The physical layer priorities of the first PUSCH and the first PUCCH are the same, that is, the physical layer priorities of the tbos and the PUCCH are the same, which may be understood as that the priority index of the tbos is the same as the priority index of the PUCCH, that is, when the priority index of the tbos is 0, the priority index of the 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 physical layer priorities are the same here, and it is not limited whether the TBoMS and the PUCCH have the same priority at a Medium Access Control (MAC) layer.

The physical layer priority may be used to indicate the priority of the service performance requirement carried on the TBoMS or PUCCH, for example, the priority index may be used to indicate the priority requirement of the low latency performance of the service carried on the TBoMS or PUCCH, and if the physical layer priorities of the TBoMS and PUCCH are different, the priority index of the TBoMS is 0, and the priority index of the PUCCH is 1, then the priority of the low latency performance requirement of the service carried on PUCCH is higher than that of the service carried on TBoMS.

The TBoMS and the PUCCH are overlapped in the time domain, which may be understood as overlapping of a resource transmitted by the TBoMS and a resource transmitted by the PUCCH in the time domain, where the PUCCH and the TBoMS are overlapped in N transmission occasions, where N is a positive integer. There are multiple scenarios where N is greater than 1, and one scenario is that when the subcarrier interval of the PUCCH and the subcarrier interval of the TBoMS are the same, multiple PUCCHs and TBoMS overlap, and the overlapping transmission timing is greater than 1. Another scenario is that when the subcarrier interval of the PUCCH and the subcarrier interval of the TBoMS are different, one PUCCH and the TBoMS overlap, and the overlapping transmission timing is greater than 1. For example, when the subcarrier spacing of PUCCH is 15khz and the subcarrier spacing of tboms is 30kHz, the duration of one slot of PUCCH is twice the duration of one slot of PUSCH. In another scenario, when the subcarrier spacing of the PUCCH and the subcarrier spacing of the TBoMS are different, and multiple PUCCHs and TBoMS overlap, the overlapping transmission timing is also greater than 1.

Next, details of K in the transmission parameters of the TBoMS are described with reference to fig. 6, where fig. 6 is a schematic structural diagram of a first PUSCH provided in the embodiment of the present application, that is, a schematic structural diagram of the TBoMS provided in the embodiment of the present application.

It should be understood that the transmission method of the TBoMS in the embodiment of the present application is a transmission method of DCI dynamic scheduling, and the transmission method of the TBoMS is not limited in the embodiment of the present application.

The frame structure used in the embodiment of the present application takes a frame structure DSUUD as an example to illustrate the transmission of TBoMS.

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

The number of transmission occasions K of the TBoMS may be understood as the number of transmission occasions K on behalf of the TBoMS, that is, the TBoMS transmits on K consecutive transmission occasions, where only P transmission occasions supporting uplink transmission are available for TBoMS transmission on the K consecutive transmission occasions, where P is a positive integer less than or equal to K, as shown in (a) of fig. 6.

As shown in (a) of fig. 6, after the terminal device receives the DCI for scheduling the TBoMS in the downlink time slot, the DCI instructs the TBoMS to transmit in K consecutive time slots, when K is 5, for the frame structure DSUUD, the terminal device transmits the TBoMS in 2 uplink time slots in the frame structure, where the actual number of time slots for transmitting the TBoMS is less than the nominal number of time slots for transmitting the TBoMS, and the two uplink time slots for transmitting the TBoMS are consecutive, and the time slots where the TBoMS is located are numbered, as shown in fig. 6.

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

As shown in fig. 6 (b), after the terminal device receives the DCI for scheduling the TBoMS on the downlink time slot, the DCI instructs the TBoMS to transmit on K uplink time slots, and when K is 4, for the frame structure DSUUD, the time slot where the TBoMS is located is numbered, as shown in the figure, the terminal device needs to finish transmitting the TBoMS, and the 2 nd uplink time slot and the 3 rd uplink time slot are separated by 3 non-uplink time slots.

It should be understood that the terminal device determines the transmission location of the TBoMS, depending on the number of slots or transmission occasions K of the TBoMS transmission and the frame structure.

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

As a possible implementation manner, the terminal device may determine the UCI type and the UCI bit number in the transmission parameter of the PUCCH, and the scaling parameter α and the code rate offset factor β in the transmission parameter of the TBoMS _offset And (5) determining the number of time-frequency resources of different types of UCI according to the parameters.

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

In the first mode, the terminal device may determine the number of time-frequency resources of the TBoMS according to parameters such as the frequency domain resource location in the transmission parameters of the TBoMS, the code modulation mode, the number of layers during MIMO transmission, the number of uplink symbols in overlapping transmission opportunities, and the number N of transmission opportunities where the PUCCH and the TBoMS overlap.

In the second mode, the terminal device may determine the number of time-frequency resources of the tbos according to parameters such as the frequency domain resource position in the transmission parameters of the tbos, the code modulation mode, the number of layers in MIMO transmission, the number of uplink symbols in the overlapping transmission opportunity, and the number of transmission opportunities K of the tbos.

S504, the terminal device sends the PUCCH and/or the first PUSCH to the access network device according to the number of the time-frequency resources of the UCI and the number of the time-frequency resources of the first PUSCH, and the access network device receives the PUCCH and/or the first PUSCH, wherein the first PUSCH only comprises one TB CRC attachment in M transmission occasions, M is smaller 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 12.

In the embodiment of the present application, the PUCCH and TBoMS in fig. 7 to 12 are transmitted by using a dynamic scheduling method, and it should be understood that this transmission method is only one example of the embodiment of the present application, and the transmission method of the PUCCH and TBoMS is not limited in the embodiment of the present application.

The frame structure in the embodiment of the present application is a DSUUD, and specific description is given in the foregoing on the frame structure of the DSUUD, so as to avoid repeated description, which is not described herein again. The timeslot diagrams shown in fig. 7 to 12 are partial timeslots with intercepted frame structures of DSUUD, that is, DDSUUDDSUUD shown in the diagrams, where downlink timeslots are numbered from left to right, and there are 5 downlink timeslots in total; numbering the special time slots from left to right, wherein the total number of the special time slots is 2; the uplink time slots are numbered from left to right, and there are 4 downlink time slots in total.

In the embodiment of the present application, UCI is divided into two categories according to different classification manners.

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

Here, satisfying the time condition for PUCCH and TBoMS transmission may be understood as sufficient processing time between the terminal device receiving the last symbol of the PDCCH or PDSCH corresponding to the PUCCH and transmitting the first symbol of the PUCCH and/or TBoMS, and sufficient processing time between the last symbol of the PDCCH corresponding to the TBoMS and transmitting the first symbol of the PUCCH and/or TBoMS.

The time condition for satisfying PUCCH transmission or the time condition for satisfying TBoMS transmission can be classified into the following cases.

Sufficient processing time exists between the terminal equipment receiving the last symbol of the PDCCH corresponding to the PUCCH and the first symbol of the PUCCH and/or the TBoMS, which can be understood as that 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 indicates the terminal equipment to feed back information such as CSI, the terminal equipment carries the UCI including the CSI in the PUCCH and/or the TBoMS and sends the UCI to the access network equipment, and a time condition that the PUCCH is satisfied, that is, sufficient processing time exists between the last symbol of the PDCCH and the first symbol of the PUCCH and/or the TBoMS.

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

In a first scenario, the PDSCH is sent to the terminal device by the access network device in a dynamic scheduling manner, that is, the terminal device needs to receive the PDCCH first, then receive the PDSCH, and then carry the UCI in the PUCCH and/or TBoMS to send to the access network device, a time condition of the PUCCH is satisfied, that is, there is enough processing time between the last symbol of the PDSCH and the first symbol of the PUCCH and/or TBoMS, and the PUCCH includes HARQ-ACK information received corresponding to the PDSCH.

And in a second scenario, the access network device sends the PDSCH to the terminal device in a semi-static transmission paradigm, that is, after the terminal device receives the PDSCH, the UCI is carried in the PUCCH and/or the TBoMS and sent to the access network device, a time condition of the PUCCH is met, that is, sufficient processing time exists between the last symbol of the PDSCH and the first symbol of the PUCCH and/or the TBoMS, and the PUCCH includes HARQ-ACK information corresponding to PDSCH reception.

Sufficient processing time exists between the terminal equipment receiving the last symbol of the PDCCH corresponding to the TBoMS and the first symbol of the PUCCH and/or TBoMS, which can be understood as that the TBoMS is transmitted by means of dynamic scheduling, that is, after the terminal equipment receives the PDCCH of the dynamic scheduling TBoMS, UCI is carried in the PUCCH and/or TBoMS and is transmitted to the access network equipment, and a time condition of the TBoMS is met, that is, sufficient processing time exists between the last symbol of the PDCCH and the first symbol of the PUCCH and/or TBoMS.

In the above, the time conditions of the PUCCH or the TBoMS are satisfied, and the time conditions of the PUCCH and the TBoMS are satisfied, that is, when the access network device sends both a PDCCH or a PDSCH corresponding to the PUCCH and a PDCCH corresponding to the TBoMS to the terminal device, and the terminal device sends the PUCCH and/or the TBoMS to the access network device, the time conditions should satisfy both the time conditions of the PUCCH and the time conditions of the TBoMS.

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

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

When a PUCCH carrying a first UCI overlaps with a tbos at N transmission occasions in a time domain, the first UCI may be multiplexed on the tbos through rate matching, or transmission of the PUCCH is cancelled, or transmission of the tbos is cancelled, where N is a positive integer, where multiplexing the first UCI on the tbos may be understood as carrying the first UCI on the tbos, that is, the first UCI is carried on the tbos.

As a possible implementation manner, multiplexing the first type of UCI on the TBoMS may be to multiplex the first type of UCI on a transmission opportunity corresponding to an overlapping portion of the PUCCH carrying the first type of UCI and the TBoMS, that is, multiplex the first type of UCI on N transmission opportunities, where the N transmission opportunities are transmission opportunities where the PUCCH carrying the first type of UCI and the TBoMS overlap in a time domain.

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

If the mode of multiplexing the first type of UCI on the TBoMS is to multiplex the first type of UCI on N transmission occasions corresponding to the overlapping portion of the PUCCH carrying the first type of UCI and the TBoMS, the number of time-frequency resources of the TBoMS is obtained in the first mode. That is, the time-frequency resource number corresponding to the TBoMS is determined according to parameters such as the frequency domain resource position in the transmission parameters of the TBoMS, the code modulation mode, the number of layers in MIMO transmission, the number of uplink symbols in the overlapped transmission opportunity, and the number N of transmission opportunities where the PUCCH and the TBoMS are overlapped.

According to the comparison result of the time frequency resource number of the TBoMS and the time frequency resource number of the first UCI, two situations of sending PUCCH or TBoMS can exist.

In case one, when the number of time-frequency resources of the TBoMS is greater than or equal to the number of time-frequency resources of the first type of UCI, the first type of UCI may be multiplexed on a transmission opportunity corresponding to an overlapping portion of a PUCCH carrying the first type of UCI and the TBoMS through rate matching, and the TBoMS may be sent.

It should be understood that the PUCCH carrying the first type of UCI may be a PUCCH multiplexed by 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 of UCI of a first type on a first PUSCH provided in an embodiment of the present application, and in fig. 7, taking a transmission opportunity as a slot as an example, subcarrier intervals of a TBoMS and a PUCCH are the same.

The terminal equipment receives DCI for scheduling PUCCH at the 1 st downlink time slot and DCI for scheduling TBoMS at the 2 nd downlink time slot, wherein the TBoMS is scheduled to be transmitted on 4 uplink time slots, and the PUCCH is scheduled to be transmitted on the 2 nd uplink time slot of the TBoMS. That is, PUCCH and TBoMS carrying UCI of the first type overlap on the 2 nd uplink slot, as shown in (a) of fig. 7.

The terminal device may multiplex the UCI of the first type through rate matching on the overlapping slot of the PUCCH carrying the UCI of the first type and the TBoMS, that is, on the 2 nd uplink slot of the TBoMS, as shown in fig. 7 (b). The specific implementation manner is that the above formulas (1) to (9) are selected to implement multiplexing the first type of UCI according to the type of the UCI.

For example, if the first type of UCI includes HARQ feedback information, CSI part 1, and CSI part2, when rate matching is performed, the number of coded modulation symbols of each layer corresponding to different types of UCI in the first type of UCI is calculated using formulas (1), (4), and (5), and then the length of a rate matching output sequence of different code blocks and an output bit sequence after rate matching are determined according to the number of coded modulation symbols of each layer, and then the rate matching output sequences sequentially concatenated with different code blocks are multiplexed onto the PUSCH. The mapping rules of the UCI of the first type on the PUSCH have different mapping orders according to the bit size of the HARQ feedback information, and specifically, when the bit size of the HARQ feedback information is greater than 2 bits, the mapping rule shown in fig. 2 is used, and 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 the first type of UCI on the transmission opportunity corresponding to the overlapped part of the PUCCH bearing the first type of UCI and the TBoMS.

In case two, when the time-frequency resource number of the TBoMS is smaller than that of the first UCI, the terminal equipment sends the PUCCH on the transmission opportunity corresponding to the overlapping part of the TBoMS and the PUCCH, and does not send the TBoMS; or the TBoMS is still transmitted at the transmission opportunity corresponding to the overlapped part of the TBoMS and the PUCCH, and the PUCCH is cancelled.

The terminal device sends the PUCCH at the transmission timing corresponding to the overlapping portion of the TBoMS and the PUCCH, but does not send the TBoMS, which may be understood as sending the PUCCH at the transmission timing corresponding to the overlapping portion of the TBoMS and the PUCCH, and sending the TBoMS at the transmission timing corresponding to the non-overlapping portion of the TBoMS and the PUCCH, where the transmission timing corresponding to the TBoMS is that M transmission timings are actually sent, M is a positive integer smaller than K, that is, the terminal device sends the TBoMS at M transmission timings, and sends the PUCCH at K-M transmission timings.

According to the scheme, when the non-repeated PUCCH and TBoMS with the same priority are overlapped, UCI borne on the PUCCH is the first-class UCI, the first-class UCI is multiplexed on the TBoMS in a rate matching mode by comparing the time-frequency resource number of the TBoMS with the time-frequency resource number of the first-class UCI and if the time-frequency resource number of the TBoMS is larger than or equal to the time-frequency resource number of the first-class UCI, the transmission performance of the UCI and uplink data can be effectively considered, and if the time-frequency resource number of the TBoMS is smaller than the time-frequency resource number of the first-class UCI, the transmission performance of the UCI or the transmission performance of the uplink data can be flexibly selected and guaranteed.

If the first type of UCI is multiplexed at the first transmission opportunity of the tbos, the number of time-frequency resources of the tbos is obtained in the foregoing second manner. That is, the number of time-frequency resources corresponding to the TBoMS is determined according to parameters such as the frequency domain resource location, the code modulation mode, the number of layers during MIMO transmission, the number of uplink symbols in the overlapping transmission opportunities, and the number of transmission opportunities K of the TBoMS in the transmission parameters of the TBoMS.

In case one, when the number of time frequency resources of the TBoMS is greater than or equal to the number of time frequency resources of the first type of UCI, the first type of UCI may multiplex the first type of UCI from a first transmission opportunity where the first PUSCH is located through rate matching.

As a possible implementation manner, the terminal device multiplexes the first type of UCI from the first transmission opportunity of the TBoMS according to the actually calculated number of time-frequency resources of the first type of UCI, where the first transmission opportunity may be the first transmission opportunity during actual transmission of the TBoMS, and may also be the first transmission opportunity on the TBoMS configured for the terminal device by the access network 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 opportunity, or may multiplex the first type of UCI on the first Z transmission opportunities, where Z is a positive integer less than or equal to K; or, multiplexing the first type of UCI on K transmission occasions; alternatively, the UCI of the first type may also be multiplexed on a transmission opportunity actually transmitted among the K transmission opportunities. The embodiment of the present application does not limit this.

For example, fig. 8 is a schematic diagram of another scheme for multiplexing UCI of a first type on a first PUSCH provided in an embodiment of the present application, and in fig. 8, taking a transmission opportunity as a slot as an example, the subcarrier intervals of a TBoMS and a PUCCH are the same.

The terminal equipment receives DCI for scheduling the 1 st PUCCH on the 1 st downlink time slot, receives DCI for scheduling the 2 nd PUCCH on the 2 nd downlink time slot, and receives DCI for scheduling TBoMS on the 1 st special time slot. The TBoMS is scheduled to transmit on 4 uplink time slots, the 1 st PUCCH is scheduled to transmit on the 2 nd uplink time slot, the 2 nd PUCCH is scheduled to transmit on the 3 rd uplink time slot, and the 1 st PUCCH and the 2 nd PUCCH both carry UCI of a first type. That is, the 1 st PUCCH and TBoMS carrying the first UCI overlap on the 2 nd uplink slot, and the 2 nd PUCCH and TBoMS carrying the first UCI overlap on the 3 rd uplink slot, as shown in fig. 8 (a).

And the terminal equipment multiplexes the first type of UCI from the 1 st time slot of the TBoMS through rate matching according to the actually calculated time-frequency resource number of the first type of UCI. For example, as shown in fig. 8 (b), the UCI of the first type is multiplexed at the 1 st and 2 nd uplink slots of the TBoMS.

The first-class UCI is multiplexed from the 1 st time slot of the TBoMS, the same-type UCI in the first-class UCI can be subjected to joint coding or independent coding, and when the joint coding is performed, the number of bits needs to be added when the number of coded modulation symbols is calculated. The same type of UCI in the first type of UCI may be understood that the 1 st PUCCH and the 2 nd PUCCH both carry the first type of UCI, and the UCIs in the two PUCCHs both belong to the first type, but specific types of UCI carried in different PUCCHs may be the same or different, for example, there is HARQ feedback information in the first type of UCI carried in the 1 st PUCCH, and there is also HARQ feedback information in the first type of UCI carried in the 2 nd PUCCH, so that such UCI may be understood as the same type of UCI in the first type of UCI.

As a possible implementation, if the first type UCI includes HARQ feedback information and CSI, the HARQ feedback information is from l of each slot ₀ Starting mapping, that is, mapping from the first symbol after the DMRS symbol of each slot; CSI from eachAnd if the first symbol in the slot, which does not carry the DMRS, starts mapping, the above equations (1) to (9) may be selected to implement multiplexing the first type of UCI according to the type of UCI. In the specific implementation, the manner of multiplexing the first-type UCI in (b) of fig. 7 is consistent with that in the foregoing, and is not described herein again to avoid repetition.

As another possible implementation manner, if the first type of UCI includes HARQ feedback information and CSI, the HARQ feedback information is from l of the 1 st slot ₀ Starting mapping, that is, mapping from the first symbol after the DMRS symbol of the 1 st slot; the CSI is mapped from the first symbol not carrying DMRS in the 1 st slot, and the formula of rate matching 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 for each layer of HARQ feedback information transmission are as shown in equation (10).

The difference between equation (1) and equation (10) is that the second part of equation (10) is to determine the upper limit of the coded modulation symbol of the HARQ feedback information according to the upper limit ratio α of the coded modulation symbol of each slot mapped on the TBoMS by UCI, i.e. the scaling parameter α, and the number K of slots corresponding to the TBoMS, wherein,

is the total number of resource units available on TBoMS for transmitting HARQ-ACK, where l ₀ A symbol index that is a symbol after a first symbol of a first DMRS that does not carry the DMRS; in addition to this, the present invention is,

defined as the number of OFDM symbols transmitted by TBoMS, i.e., the total number of OFDM symbols over K transmission occasions.

If the first type of UCI includes CG-UCI and CSI information, each layer of coded modulation symbols for CG-UCI transmission is as 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 is not described herein again to avoid redundancy.

If the first type UCI includes HARQ feedback information, CG-UCI, and CSI information, each layer of coded modulation symbols for HARQ feedback information transmission is as 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 is not described herein again to avoid repetition.

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

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 is not described herein again to avoid redundancy.

The CSI information is composed of CSI part 1 and CSI part2, the number of coded modulation symbols of each layer of the CSI part 1 is obtained by calculation of a formula (7), and the number of coded modulation symbols of each layer of the CSI part2 is obtained by calculation of a formula (8). If no CSI part2 is determined, the number of coded modulation symbols of each layer of CSI part 1 is calculated by formula (9).

And the terminal equipment maps different types of UCI in the first type of UCI from the first time slot of the TBoMS according to the formula until the first type of UCI is mapped. The mapping rule of the UCI of the first type on the TBoMS refers to the mapping rule of the UCI and the UL-SCH on the PUSCH in fig. 2 to 4.

In case two, when the time-frequency resource number of the TBoMS is smaller than the time-frequency resource number of the first UCI, the terminal equipment sends the PUCCH at the transmission opportunity where the PUCCH is located, and does not send the TBoMS at the transmission opportunity where the TBoMS is located; or sending the TBoMS at the transmission opportunity of the TBoMS, that is, transmitting one PUSCH transmission block in K slots, and canceling sending the PUCCH.

Fig. 9 and 10 show a scheme of multiplexing the second type of UCI on the TBoMS when the PUCCH carrying the second type of UCI overlaps with the TBoMS.

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

As a possible implementation manner, the second type UCI multiplexing on the tbos may be that the second type UCI performs puncturing on transmission timings corresponding to an overlapping portion of the tbos and the PUCCH, that is, N transmission timings where the tbos and the PUCCH overlap, where N is a positive integer.

It should be understood that the second type of UCI punctures the transmission timing corresponding to the overlapping portion of the tbos and the PUCCH, and covers the original UL-SCH of the tbos on the N transmission timings corresponding to the overlapping portion according to the bit number of the second type of UCI, and the reason why the second type of UCI punctures the transmission timing corresponding to the overlapping portion of the tbos and the PUCCH is that the terminal device has insufficient time to map the second type of UCI and the UL-SCH on the transmission timing corresponding to the overlapping portion through rate matching.

As a possible implementation manner, the terminal device defines the time condition of puncturing according to the transmission timing position of the scheduled PUCCH, the processing time of the terminal device, and the start symbol position of the transmission timing corresponding to the overlapping portion. When the second type of UCI performs puncturing at a transmission timing corresponding to an overlapping portion of the tbos and the PUCCH, a defined puncturing time condition needs to be satisfied.

As a possible implementation manner, the time-frequency resource number size of the TBoMS is obtained in the foregoing manner. That is, the time-frequency resource number corresponding to the TBoMS is determined according to parameters such as the frequency domain resource position in the transmission parameters of the TBoMS, the code modulation mode, the number of layers in MIMO transmission, the number of uplink symbols in the overlapped transmission opportunity, and the number N of transmission opportunities where the PUCCH and the TBoMS are overlapped.

According to the comparison result of the time frequency resource number of the TBoMS and the time frequency resource number of the second UCI, two situations of sending PUCCH or TBoMS can exist.

In case one, when the number of time frequency resources of the 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 perform puncturing on a transmission opportunity corresponding to an overlapping portion of a PUCCH carrying the second type of UCI and the TBoMS.

For example, fig. 9 is a schematic diagram of a multiplexing scheme of a second type of UCI on a first PUSCH provided in an embodiment of the present application, and fig. 9 takes a transmission opportunity as a slot as an example, and the subcarrier intervals of a TBoMS and a PUCCH are the same.

And the terminal equipment receives DCI for scheduling TBoMS at the 3 rd downlink time slot and receives DCI for scheduling PUCCH at the 2 nd downlink time slot, wherein the TBoMS is scheduled to be transmitted on 4 uplink time slots, and the PUCCH is scheduled to be transmitted on the 3 rd uplink time slot of the TBoMS. That is, PUCCH and TBoMS carrying UCI of the first type overlap on the 3 rd uplink slot, as shown in fig. 9 (a).

The terminal device may puncture the second type UCI in the overlapping time slot of the PUCCH carrying the second type UCI and the TBoMS, that is, puncture the second type UCI in the 3 rd uplink time slot of the TBoMS, as shown in fig. 9 (b), and send the TBoMS.

For example, fig. 10 is a schematic diagram of another second type of UCI multiplexing scheme on a first PUSCH provided in an embodiment of the present application, where in fig. 10, taking a transmission opportunity as a slot as an example, a subcarrier interval of a TBoMS and a PUCCH is different, the subcarrier interval of the TBoMS is twice as large as that of the PUCCH, and a duration of one slot of the PUCCH is twice as large as that of one slot of the TBoMS.

And the terminal equipment receives DCI for scheduling TBoMS in the 2 nd downlink time slot and receives DCI for scheduling PUCCH in the 3 rd downlink time slot. Wherein, the TBoMS is scheduled to transmit on 4 uplink time slots, and the PUCCH is scheduled to transmit on the 3 rd and 4 th uplink time slots of the TBoMS. That is, PUCCH and TBoMS carrying UCI of the first type overlap on 3 rd and 4 th uplink slots of TBoMS, as shown in fig. 10 (a).

As a possible implementation manner, the terminal device transmits the PUCCH in the slot corresponding to the overlapping portion of the TBoMS and the PUCCH, and does not transmit the TBoMS, as shown in fig. 10 (b), the PUCCH is transmitted in the 3 rd and 4 th uplink slots where the TBoMS and the PUCCH overlap, the TBoMS is not transmitted in the 3 rd and 4 th uplink slots, and only the partial TBoMS is transmitted in the 1 st and 2 nd uplink slots.

As another possible implementation manner, the terminal device still sends the TBoMS in the slot corresponding to the overlapping portion of the TBoMS and the PUCCH, and does not send the PUCCH, as shown in fig. 10 (c), the TBoMS is sent in the 1 st to 4 th uplink slots, and the PUCCH that originally needs to be transmitted in the 3 rd and 4 th uplink slots is cancelled.

According to the scheme, when the non-repeated PUCCHs and TBoMSs with the same priority are overlapped, the UCI borne on the PUCCHs is the second type of UCI, and by comparing the time-frequency resource number of the TBoMS with the time-frequency resource number of the second type of UCI, if the time-frequency resource number of the TBoMS is larger than or equal to the time-frequency resource number of the second type of UCI, the second type of UCI punches holes on the transmission opportunity corresponding to the overlapped part of the PUCCHs and the TBoMS which bear the second type of UCI, so that the terminal equipment can effectively take the transmission performance of the UCI and the uplink data into consideration in the limited time-frequency processing time, and if the time-frequency resource number of the TBoMS is smaller than the time-frequency resource number of the first type of UCI, the terminal equipment can flexibly select to ensure the transmission performance of the UCI or the transmission performance of the uplink data.

Fig. 11 to 13 show transmission schemes of a PUCCH and a TBoMS when the PUCCH carrying the second type of UCI overlaps with the PUCCH carrying the first type of UCI.

Fig. 11 shows a possible scheme for transmitting PUCCH or TBoMS when PUCCH carrying UCI of the first type and PUCCH carrying UCI of the second type are not scheduled on the same transmission opportunity.

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 time, that is, the access network device does not send scheduling information to the terminal device, where the PUCCH carrying the second type of UCI and the PUCCH carrying the first type of UCI are scheduled at the same transmission time. The terminal equipment does not punch the second type of UCI at the transmission time corresponding to the first type of UCI which is multiplexed by the rate matching.

As a possible implementation manner, the terminal device may transmit the TBoMS and/or the PUCCH by using the scheme of multiplexing the first type of UCI on the TBoMS, which is not described herein again to avoid repetition. The terminal device may transmit the tbos and/or the PUCCH by the foregoing scheme of multiplexing the second type of UCI on the tbos, and for avoiding repetition, details are not described herein, and the second type of UCI cannot be punctured at the transmission time of multiplexing the first type of UCI.

For example, fig. 11 is a schematic diagram of a multiplexing scheme of a first type UCI and a second type UCI on a first PUSCH provided in an embodiment of the present application, and fig. 11 takes a transmission opportunity as a slot as an example, and the subcarrier intervals of a TBoMS and a PUCCH are the same.

The terminal device receives, at the 1 st downlink slot, DCI scheduling a PUCCH carrying a first type of UCI, where the PUCCH carrying the first type of UCI is the first PUCCH in (a) in fig. 11, receives, at the 2 nd downlink slot, DCI scheduling a PUCCH carrying a second type of UCI, where the PUCCH carrying the second type of UCI is the second PUCCH in (a) in fig. 11, and receives, at the 1 st downlink slot, DCI scheduling TBoMS. Wherein, the TBoMS is scheduled to transmit on 4 uplink time slots, and the first PUCCH is scheduled to transmit on the 1 st uplink time slot of the TBoMS. That is, the PUCCH and TBoMS carrying the UCI of the first type are overlapped on the 1 st uplink slot; the second PUCCH is scheduled for transmission on the 3 rd uplink slot of the TBoMS. That is, PUCCH and TBoMS carrying UCI of the second type overlap on the 3 rd uplink slot, as shown in fig. 11 (a). The access network device does not schedule the PUCCH carrying the second type of UCI and the PUCCH carrying the first type of UCI on the same transmission opportunity.

The terminal device may multiplex the UCI of the first type through rate matching on the overlapping slot of the PUCCH carrying the UCI of the first type and the TBoMS, that is, on the 1 st uplink slot of the TBoMS, as shown in (b) of fig. 11. The terminal device may puncture the second type of UCI in the overlapping slot of the PUCCH carrying the second type of UCI and the TBoMS, that is, in the 3 rd uplink slot of the TBoMS, as shown in fig. 11 (b), and transmit the TBoMS. It should be understood that the multiplexing manner of the UCI of the first type and the UCI of the second type on the TBoMS shown in (b) of fig. 11 is only an example.

According to the scheme, the terminal equipment does not expect the PUCCH bearing the second UCI, and the transmission opportunity of the PUCCH bearing the first UCI is scheduled, so that the situation that the first UCI is knocked off by punching of the second UCI can be avoided, and meanwhile, the number of symbols occupying UL-SCH is reduced, namely, the transmission performance of the first UCI and the UL-SCH is ensured.

Fig. 12 and 13 show possible transmission schemes of PUCCH or TBoMS for a terminal device when PUCCH carrying first type UCI and PUCCH carrying second type UCI are scheduled on the same transmission opportunity

When the PUCCH and TBoMS carrying the first UCI are overlapped on N transmission occasions in the time domain, the PUCCH and TBoMS carrying the second UCI are overlapped on N transmission occasions in the time domain, and the PUCCH carrying the first UCI and the PUCCH carrying the second UCI are overlapped on the same transmission occasion. If the time frequency resource number of the TBoMS is larger than the time frequency resource number of the first type of UCI and the second type of UCI, the terminal equipment can determine the transmission modes of the first type of UCI and the second type of UCI.

As a possible implementation manner, the terminal device may multiplex the first type of UCI on the TBoMS by rate matching, and then punch 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 a multiplexing scheme of another first-type UCI and second-type UCI on a first PUSCH in this embodiment of the application, and fig. 12 takes a transmission opportunity as a slot as an example, and the subcarrier intervals of a TBoMS and a PUCCH are the same.

The terminal device receives, at the 1 st downlink slot, DCI scheduling a PUCCH carrying a first type of UCI, where the PUCCH carrying the first type of UCI is the first PUCCH in (a) in fig. 12, receives, at the 3 rd downlink slot, DCI scheduling a PUCCH carrying a second type of UCI, where the PUCCH carrying the second type of UCI is the second PUCCH in (a) in fig. 12, and receives, at the 2 nd downlink slot, DCI scheduling TBoMS. Wherein, the TBoMS is scheduled to transmit on 4 uplink time slots, the first PUCCH is scheduled to transmit on the 3 rd uplink time slot of the TBoMS, and the second PUCCH is also scheduled to transmit on the 3 rd uplink time slot of the TBoMS. That is, the PUCCH carrying the UCI of the first type, the PUCCH carrying the UCI of the second type, and the TBoMS overlap on the same slot, that is, the 3 rd uplink slot, as shown in fig. 12 (a). And the access network equipment schedules the PUCCH bearing the second UCI and the PUCCH bearing the first UCI on the same transmission opportunity.

The terminal device may multiplex the first type of UCI through rate matching on the overlapping slot of the PUCCH carrying the first type of UCI and the TBoMS, that is, on the 3 rd uplink slot of the TBoMS, and the second type of UCI is punctured on the 4 th uplink slot, as shown in fig. 12 (b).

As another possible implementation manner, the terminal device may multiplex the first type of UCI on the TBoMS by performing rate matching, and then punch the second type of UCI on the resource units corresponding to the first type of UCI except the HARQ feedback information.

The second type of UCI may puncture the resource units corresponding to the first type of UCI, but may not puncture the time-frequency resources corresponding to the HARQ feedback information in the first type of UCI.

As a possible implementation manner, for example, as shown in fig. 13, a terminal device may puncture time-frequency resources corresponding to an UL-SCH, fig. 13 is a schematic diagram of a multiplexing scheme of a first UCI and a second UCI in the embodiment of the present application on a first PUSCH, and in fig. 13, taking a transmission opportunity as a slot as an example, subcarrier intervals of a TBoMS and a PUCCH are the same.

The scheduling condition received by the terminal device is the same as that in (a) of fig. 12, that is, (a) of fig. 13 is the same as that in (a) of fig. 12, and details are not repeated herein to avoid repetition.

The terminal device may multiplex the first type UCI through rate matching on the time slot where the PUCCH carrying the first type UCI overlaps with the TBoMS, that is, on the 3 rd uplink time slot of the TBoMS, and the second type UCI punctures the time slot where the first type UCI is located, but skips the number of time-frequency resources corresponding to the first type UCI and directly punctures the number of time-frequency resources corresponding to the UL-SCH on the 3 rd uplink time slot, as shown in fig. 13 (b).

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 part2 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 the CSI in the transmission opportunity where the first type of UCI is located.

As a possible implementation manner, the second type of UCI may also puncture forward from the last symbol in the transmission opportunity of the first type of UCI. Such as puncturing from the 14 th symbol onward, or such as from the first symbol after the last set of consecutive symbols carrying DMRS.

As a possible implementation manner, if the bit of the HARQ feedback information is 0 and there is no CG-UCI, as shown in fig. 4, the terminal device reserves resources for the HARQ feedback information, and the second type of UCI may preferentially puncture the number of reserved time-frequency resources.

According to the scheme, when the non-repeated PUCCH bearing the first type of UCI, the non-repeated PUCCH bearing the second type of UCI and TBoMS with the same priority are overlapped on the same transmission time, the first type of UCI and the second type of UCI meet different conditions, the first type of UCI is respectively multiplexed on the TBoMS in a rate matching mode according to the time-frequency resource number of the first type of UCI and the second type of UCI and the time-frequency resource number of the TBoMS, the second type of UCI punches at a proper position on the TBoMS, and the second type of UCI punches on the TBoMS, so that the transmission of the first type of UCI is avoided to a great extent.

As a possible implementation manner, the terminal device does not expect DCI indication PUCCH for scheduling PUCCH, and DCI indication PUSCH for scheduling first PUSCH overlaps in time domain. When the DCI for scheduling the PUCCH or the DCI for scheduling the first PUSCH indicates that the PUCCH and the first PUSCH are not overlapped in a time domain, the terminal equipment determines that UCI carried on the PUCCH is not multiplexed to be transmitted on the first PUSCH, and the terminal equipment sends the PUCCH and the first PUSCH.

At present, an aperiodic CSI report may be triggered to be sent on a PUSCH, and an embodiment of the present application provides a multiplexing manner when the aperiodic CSI report is triggered on a first PUSCH, where the first PUSCH transmits one PUSCH transport block at K transmission occasions and only one TB cyclic redundancy check CRC is attached. The first PUSCH may be referred to as a TBoMS, and the first PUSCH may also have other names, which is not limited in this embodiment of the present application.

Fig. 14 is a flowchart illustrating another information sending method according to an embodiment of the present application.

S1401, the radio access network equipment sends the transmission parameter of the first PUSCH to the terminal equipment, the transmission parameter of the first PUSCH includes the number K of the transmission opportunity, K is a positive integer greater than or equal to 2, the first PUSCH only includes a transmission block TB Cyclic Redundancy Check (CRC) attachment on K transmission opportunities.

As a possible implementation manner, the transmission parameter of the first PUSCH may be carried in the DCI for indicating the physical layer, or may be carried in other messages in which the transmission parameter of the first PUSCH can be transmitted, which is not limited in this embodiment of the present invention.

As a possible implementation manner, the physical layer indicates that the DCI may also carry a transmission parameter of the aperiodic CSI, where the transmission parameter of the aperiodic CSI and the transmission parameter of the first PUSCH are carried in the same message, and the transmission parameter of the aperiodic CSI is used to indicate that the aperiodic CSI is multiplexed on the first PUSCH by the terminal device.

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

The transmission parameters of the TBoMS may include at least one of the following parameters: frequency domain resource position, subcarrier interval configuration mu, coding modulation mode, layer number during MIMO transmission, scaling parameter alpha and code rate offset factor beta _offset TBoMS priority index and TBoMS transmission opportunity number K. It should be understood that these parameters are the transmission parameters of the TBoMS referred to in the embodiments of the present application, and not all the TBoMS.

The terminal device may determine a subcarrier spacing Δ f =2 of the TBoMS according to the subcarrier spacing configuration μ ^μ ·15[kHz]。

The terminal equipment can transmit according to MIMONumber of layers, scaling parameter alpha and code rate offset factor beta in transmission _offset And when the UCI is multiplexed on the TBoMS, determining the number of coded modulation symbols of each layer of different types of UCI.

The terminal device may determine that one PUSCH transmission block is transmitted on K transmission occasions according to the number K of transmission occasions where TBoMS transmission continues, where the transmission occasions may include slots or transmission occasions.

The transmission opportunity may include one or more time slots, and may also include one time slot or a part of symbols in multiple time slots, for example, one transmission opportunity may include 3 rd to 12 th symbols, and the number and positions of the symbols included in the transmission opportunity are not limited in this embodiment of the application.

Wherein, the first PUSCH has only one transport block TB cyclic redundancy check CRC attached on K transmission occasions, which can be understood as that the first PUSCH transmits only one PUSCH transport block on K transmission occasions and has only one PUSCH transport block CRC attached.

S1402, the terminal device sends a first PUSCH according to the transmission parameter of the first PUSCH, wherein the first PUSCH multiplexes the aperiodic Channel State Information (CSI).

The following describes in detail the multiplexing manner of aperiodic CSI on TBoMS, that is, the multiplexing manner of aperiodic CSI on the first PUSCH, with reference to fig. 15 to 17.

The time slot diagrams shown in fig. 15 to 17 are partial time slots obtained by intercepting a frame structure of DSUUD, and numbering downlink time slots from left to right, where there are 5 downlink time slots in total; numbering the special time slots from left to right, wherein the total number of the special time slots is 2; the uplink time slots are numbered from left to right, and there are 4 downlink time slots in total.

As a possible implementation manner, the terminal device may multiplex the aperiodic CSI on the first transmission occasion corresponding to the first PUSCH.

For example, fig. 15 is a schematic diagram of a multiplexing manner of aperiodic CSI on a first PUSCH provided in an embodiment of the present application, and fig. 15 takes a transmission opportunity as a slot as an example.

The terminal equipment receives DCI for scheduling TBoMS in the 2 nd downlink time slot, wherein the TBoMS is scheduled to be transmitted in 4 uplink time slots, and the DCI comprises transmission parameters of aperiodic CSI and transmission parameters of the TBoMS. The terminal device multiplexes aperiodic CSI in the 1 st uplink slot in the TBoMS by rate matching, as shown in fig. 15, and then transmits the TBoMS.

As a possible implementation manner, the terminal device may multiplex the aperiodic CSI from the first transmission occasion corresponding to the first PUSCH until the aperiodic CSI bit mapping is finished. The terminal equipment may multiplex the aperiodic CSI from the first transmission opportunity where the TBoMS is located according to the number of the aperiodic CSI actual time frequency resources.

For example, fig. 16 is a schematic diagram of another multiplexing manner of aperiodic CSI provided in the embodiment of the present application on a first PUSCH, and fig. 16 takes a transmission opportunity as a slot as an example.

The terminal equipment receives DCI for scheduling TBoMS in the 2 nd downlink time slot, wherein the TBoMS is scheduled to be transmitted in 4 uplink time slots, and the DCI comprises transmission parameters of aperiodic CSI and transmission parameters of the TBoMS. The terminal device multiplexes the aperiodic CSI from the 1 st uplink time slot of the tbos through rate matching according to the number of time-frequency resources actually required by the aperiodic CSI until the mapping of the aperiodic CSI is finished, as shown in fig. 16, the aperiodic CSI is sent out on the first 2 uplink time slots, and then the tbos is sent.

As a possible implementation manner, the terminal device may start multiplexing the aperiodic CSI on each transmission occasion corresponding to the first PUSCH, wherein the terminal device may split the aperiodic CSI on each transmission occasion of the first PUSCH or may repeatedly multiplex the aperiodic CSI on each transmission occasion of the first PUSCH.

For example, fig. 17 is a schematic diagram of a multiplexing manner of still another aperiodic CSI provided in an embodiment of the present application on a first PUSCH, and fig. 17 takes a transmission opportunity as a slot as an example.

The terminal equipment receives DCI for scheduling TBoMS in the 2 nd downlink time slot, wherein the TBoMS is scheduled to be transmitted in 4 uplink time slots, and the DCI comprises transmission parameters of aperiodic CSI and transmission parameters of the TBoMS. The terminal device, according to the number of time-frequency resources actually required by the aperiodic CSI, averagely apportions and maps the aperiodic CSI on the 1 st to 4 th uplink slots of the tbos through rate matching, or repeatedly multiplexes the aperiodic CSI on the 1 st to 4 th uplink slots of the tbos, that is, in the 1 st to 4 th uplink slots of the tbos, the aperiodic CSI multiplexed in each uplink slot is the same, and then sends the tbos as shown in fig. 17.

According to the scheme, when the aperiodic CSI is scheduled to be sent on the TBoMS, the periodic CSI is multiplexed on the TBoMS in a rate matching mode, and the transmission performance of the aperiodic CSI and the UL-SCH on the TBoMS can be simultaneously ensured to a certain extent.
