Description

Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and apparatus.

Background

In order to enhance the uplink coverage performance of a New Radio (NR), a transport block over multi-slot (TBoMS) technique is proposed. The technology aggregates small data packets on a plurality of original time slots into a large data packet, and completes the transmission of the large data packet on the plurality of time slots.

Currently, when there is an overlap between a Physical Uplink Control Channel (PUCCH) transmission and a Physical Uplink Shared Channel (PUSCH) transmission in a time domain, and the PUCCH transmission and the PUSCH transmission satisfy a preset condition that Uplink Control Information (UCI) is multiplexed on the PUSCH, UCI originally carried on the PUCCH transmission may be multiplexed on the PUSCH for transmission, that is, UCI is transmitted through the PUSCH without transmitting the PUCCH.

Since the above scheme is designed based on a scenario that PUSCH is located in one slot, for uplink transmission of TBoMS, the above scheme is not applicable to TBoMS since one TBoMS may span multiple slots. There is currently no good solution for how to transmit PUCCH transmissions and TBoMS-based PUSCH transmissions when there is overlap in the time domain.

Detailed Description

To facilitate understanding of the embodiments of the present application, a brief description will first be given below in conjunction with several terms referred to in the present application.

1. Demodulation reference signal

The demodulation reference signal is a reference signal for data demodulation. The demodulation reference signal may be a demodulation reference signal (DMRS) in a Long Term Evolution (LTE) protocol or an NR protocol, or may also be other reference signals defined in a future protocol for implementing the same function. In LTE or NR protocols, DMRS may be carried in a physical shared channel and transmitted together with data block signals for channel estimation of a fading channel, thereby completing demodulation of the data block signals carried in the physical shared channel. For example, the downlink data block is transmitted together with a Physical Downlink Shared Channel (PDSCH) or the uplink data block is transmitted together with a PUSCH. In the embodiment of the present application, the demodulation reference signal may include a demodulation reference signal transmitted through a physical uplink shared channel.

2. Time slot (slot)

One slot format may be an OFDM (orthogonal frequency division multiplexing) symbol containing a number of Orthogonal Frequency Division Multiplexing (OFDM) symbols. For example, a slot format may include 14 OFDM symbols, or a slot format may include 12 OFDM symbols; alternatively, one slot format is to contain 7 OFDM symbols. The OFDM symbols in one slot may be all used for uplink transmission; can be used for downlink transmission; and a part of the time domain symbols can be used for downlink transmission, a part of the time domain symbols can be used for uplink transmission, and a part of the time domain symbols can be flexibly configured to be used for uplink or downlink transmission. It should be understood that the above examples are illustrative only, and should not be construed as limiting the present application in any way. The number of OFDM symbols contained in a slot and the use of the slot for uplink transmission and/or downlink transmission are not limited to the above examples for system forward compatibility. In this application, the time domain symbol may be an OFDM symbol, i.e., the time domain symbol may be replaced with an OFDM symbol.

3. Redundancy version (redundancy version, RV)

The RV is designed to implement Incremental Redundancy (IR) hybrid automatic repeat request (HARQ) transmission, that is, redundancy bits generated by an encoder are divided into a plurality of groups, each RV defines a transmission start point, and different RVs are used for first transmission and HARQ retransmissions to implement gradual accumulation of the redundancy bits and complete incremental redundancy HARQ operation.

4. Rate matching

After the information bit string is transmitted and channel coded to obtain a longer coded bit string, not all the coded bit strings are transmitted directly. Generally, the terminal device may determine how many bits can be sent according to the number of available Resource Elements (REs) and the modulation order configured to the terminal by the network device, and further select from the coded bit string (the current protocol specifies 4 starting points, which are approximately uniformly distributed in the coded bit string and are respectively marked as RV0, RV1, RV2, and RV 3). This process may be referred to as rate matching.

For example, the number of available REs =12 × 12=144 in the current 1 Resource Block (RB), and with Quadrature Phase Shift Keying (QPSK) modulation, 144 × 2=288 bits can be carried in the 1 Physical Resource Block (PRB). Therefore, 288 bits need to be selected from the coded bit string of 500 bits as a selected bit string, and then the selected bit string needs to be subjected to processing such as modulation and resource mapping. At this time, the corresponding transmission code rate = information bit string/selected bit string length =100/288.

5. Transmission opportunities (Transmission opportunities of TBoMS, TOT)

The TOT is a time unit involved in the uplink transmission process of TboMS, and includes one or more consecutive time slots for uplink transmission. For example, the TOT may be a time unit corresponding to a redundancy version of the first transport block. Alternatively, the TOT may also be a rate-matched time unit. Alternatively, the TOT may also be composed of consecutive P timeslots for uplink transmission, where P is an integer greater than 0, and P is predefined or indicated by the network device. Alternatively, the TOT may be a time unit determined by other rules. It should be understood that "TOT" is merely an exemplary designation, and the embodiments of the present application do not specifically limit the designation of such time units.

The foregoing describes some of the noun concepts related to embodiments of the present application, and the following describes some features related to embodiments of the present application.

If the PUCCH transmission and the PUSCH transmission overlap in the time domain, and the PUCCH and PUSCH transmission satisfy a condition that Uplink Control Information (UCI) is multiplexed on the PUSCH, the UCI originally carried on the PUCCH transmission is multiplexed on the PUSCH and transmitted, that is, the UCI is transmitted through the PUSCH, and the PUCCH is not transmitted.

When the PUSCH adopts the repeated transmission of the type A, if one PUCCH transmission generates time domain overlapping with the PUSCH transmission in one or more time slots and the condition that UCI is multiplexed on the PUSCH is met, the terminal equipment multiplexes the UCI on one PUSCH in the time slot overlapped with the PUCCH. For example, PUSCH repeated transmission transmits PUSCH in 3 slots (slot #1, slot #2, slot # 3), where PUSCH transmission in slot #1 and slot #2 overlaps PUCCH, i.e., slot #1 and slot #2 are repeated slots, when the terminal device multiplexes UCI on the PUCCH on PUSCH in slot #1 and slot #2 for transmission, without transmitting PUCCH, as shown in fig. 1.

Under the condition that the UCI and an uplink-shared channel (UL-SCH) are carried on the PUSCH, the terminal device may map the coded UCI to the PUSCH after multiplexing with the UL-SCH in a rate matching manner, or may map the coded UCI to the PUSCH in a manner that puncturing (puncturing) has been mapped to the UL-SCH on the PUSCH, thereby implementing multiplexing with the UL-SCH. The UCI is mapped on the first time domain symbol after the DMRS symbol and the UL-SCH is mapped on the remaining time domain symbols in the PUSCH.

However, for uplink transmission across a multi-slot transport block (TBoMS), the TBoMS spans multiple slots, and the TBoMS may perform rate matching for each slot, or perform rate matching for each TOT, or perform rate matching in all slots. The multiple time slots occupied by the TBoMS can be divided into one or more TOTs, as shown in fig. 2, one TBoMS spans 6 time slots, and the 6 time slots may include 2 TOTs, and how to multiplex UCI in the TBoMS becomes a problem to be solved.

Based on this, embodiments of the present application provide a communication method and apparatus, which may provide a transmission scheme when overlapping resources exist in a time domain for PUCCH transmission and a transmission block based on cross-slot transmission. The method and the device are based on the same inventive concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not described again.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: may be the internet of things (IoT),Narrowband band Internet of things (NB-IoT), LTE, and also can be the fifth generation (5) ^th generation, 5G) communication system, may also be a mixed architecture of LTE and 5G, may also be a new communication system appearing in 6G or future communication development, and the like. The 5G communication system described herein may include at least one of a non-standalone (NSA) 5G communication system and a Standalone (SA) 5G communication system. The communication system may also be an M2M network, MTC, or other network.

As shown in fig. 3, the communication method provided in the embodiment of the present application may be applied to a communication system, where the communication system includes a network device and six terminal devices, that is, UE1 to UE6. In the communication system, the UEs 1 to 6 may transmit uplink information to the network device, and the network device may receive uplink data transmitted by the UEs 1 to 6. Further, UE4 to UE6 may also constitute one sub-communication system. The network device may send downlink information to the UE1, the UE2, the UE3, and the UE5, where the UE5 may send the downlink information to the UE4 and the UE6 based on a device-to-device (D2D) technology, or the UEs 4 to 6 may communicate with each other based on a device-to-device (D2D) technology.

The embodiment of the application can also be used for other communication systems as long as the communication system needs to carry out cross-time-slot uplink transmission. In addition, the embodiment of the application is not only suitable for a scene of communication between one network device and one UE, but also suitable for a scene of communication between one network device and a plurality of UEs, or a plurality of network devices cooperate to simultaneously communicate with one or a plurality of UEs.

In the embodiment of the application, "in 8230; \8230in the case of \ 8230;" in 8230, it can also be described as "if 8230;" or "if" or "when 8230; \8230, and so on. For example, "in the case that n first time units in the first time domain resource are respectively overlapped with the second time domain resource to be in the first state", it may also be described as "if the n first time units in the first time domain resource are respectively overlapped with the second time domain resource", or "when the n first time units in the first time domain resource are respectively overlapped with the second time domain resource", or the like.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It should be understood that the processing performed by a single execution main body (terminal device or network device) shown in the embodiments of the present application may also be divided into multiple execution main bodies for execution, which may be logically and/or physically separated, for example, the processing performed by the network device may be divided into at least one of CU, DU, and RU for execution.

Referring to fig. 4, a flowchart of a communication method provided in the present application is shown. The method comprises the following steps:

s401, the terminal device determines that n first time units in the first time domain resource are respectively overlapped with the second time domain resource.

The first time domain resource is configured to transmit a first transport block, the second time domain resource is used for transmitting PUCCH, and n is an integer larger than 1.

Illustratively, the first time domain resource may be a time domain resource allocated to the first transport block. For example, the time domain resource may be a plurality of consecutive time slots, e.g., the first time domain resource may include 10 time slots starting from time slot t. It should be understood that the first time domain resource is only illustrated here, and the size of the first time domain resource is not limited. The time domain resource may include an uplink time slot, a downlink time slot, and may further include a special time slot, where symbols included in the uplink time slot are all used for uplink transmission, symbols included in the downlink time slot are all used for downlink, and the special time slot includes at least one of the following: symbols for downlink transmission, symbols for determining a transmission direction based on a configuration.

The first time domain resource may correspond to a plurality of first time units, and the n first time units overlapping the second time domain resource are part or all of the plurality of first time units. The description of the first time unit may refer to the description of TOT in the above term introduction 5), and will not be repeated herein. For convenience of description of the scheme, the first time unit is referred to as TOT hereinafter, and it should be understood that the naming of the first time unit is merely an exemplary naming and is not limiting.

For example, as shown in fig. 5, the first time domain resource includes 20 time slots corresponding to 4 TOTs, which are TOT1 to TOT4 respectively. Wherein, TOT1 includes 3 time slots, TOT2 includes 6 time slots, TOT3 includes 4 time slots, and TOT4 includes 7 time slots. All 3 TOTs in the first time domain resource are overlapped with the second time domain resource, namely TOT 2-TOT 4 are overlapped with the second time domain resource.

In the embodiment of the present application, the overlapping may be complete overlapping or partial overlapping, and the overlapping may be understood as that the starting positions, the ending positions, and the lengths of the two time domain resources are the same. Two time domain resources can be considered to overlap as long as there are overlapping resources on the two time domain resources, for example, as long as there is overlapping time domain resource on one TOT and the second time domain resource, that is, the TOT and the second time domain resource overlap.

Optionally, before step S401, the terminal device may determine time domain resources occupied by the first transport block in the first time domain resources, that is, resources used for sending the first transport block in the first time domain resources, such as time slots used for sending the first transport block in the first time domain resources, and symbols used for sending the first transport block on each time slot.

In one implementation, the network device may send indication information to the terminal device, where the indication information may indicate a starting symbol and a length, so that the terminal device may determine a symbol in each slot for sending the first transport block. For example, the indication information may indicate a row of a time domain resource table, where each row of the time domain resource table includes a starting symbol S and a number of symbols L. The indication information may be carried in Downlink Control Information (DCI) or in higher layer signaling.

Further, the indication information may also indicate a number of slots, where the number of slots is the number of slots used for transmitting the first transport block. For example, the indication information may indicate a row of a time domain resource table, where each row of the time domain resource table includes a start symbol S and a number of symbols L, and each row of the time domain resource table corresponds to a number of slots N. Alternatively, the time slot number may be indicated to the terminal device by the network device through other high layer signaling.

The indication information may also indicate the starting time slot of the first transport block, i.e. the first time slot allocated to the first transport block.

For example, assuming that one slot includes 14 symbols, i.e., symbols 0 to 12, the indication information indicates that the start symbol is 2, the length is 12, and the number of slots is 4, the terminal device may determine 4 slots for transmitting the first transport block, and transmit the first transport block on symbols 2 to 13 of each slot, as shown in fig. 6.

S402, the terminal device determines a third time domain resource in n first time units.

In one implementation, the time unit of the third time domain resource may be a TOT. That is, the terminal device may determine one or more TOTs as the third time domain resource in the n first time units (i.e., n TOTs).

In another implementation, the time unit of the third time domain resource may also be a time slot. That is, the terminal device may determine one or more time slots among the time slots overlapping with the second time domain resource in the n TOTs as the third time domain resource.

S403, the network device determines that n first time units in the first time domain resource are respectively overlapped with the second time domain resource.

The implementation method of step S403 is the same as that of step S401, and specifically, reference may be made to the relevant description of step S401, and details are not repeated here.

S404, the network device determines a third time domain resource in the n first time units.

The implementation method of step S404 is the same as that of step S402, and reference may be specifically made to the related description of step S402, which is not repeated herein.

It should be noted that steps S401 and S403 may be optional steps, that is, the terminal device (or the network device) may determine the third time domain resource in n first time units when the n first time units in the first time domain resource are respectively overlapped with the second time domain resource.

S402 and S404 are not strictly chronological in execution.

S405, the terminal device sends at least one of the following on the third time domain resource: UCI carried by PUCCH, first coded bit. Accordingly, the network device receives, on the third time domain resource, at least one of: UCI carried by PUCCH, first coded bit.

The first coded bit is a coded bit that should be carried on the third time domain resource in the first transport block, that is, a coded bit that should be carried on the third time domain resource in the first transport block and corresponds to the first UL-SCH. The first coded bit may also be replaced with the first UL-SCH.

In one implementation, the terminal device may multiplex the UCI and the first coded bit on the third time domain resource for transmission. For example, the terminal device may map the UCI to the PUSCH after multiplexing with the first coded bit in a rate matching manner. A specific transmission manner will be described below with reference to the third time domain resource.

In another implementation, the terminal device may also transmit the UCI or the first coded bits in a puncturing manner. For example, when the UCI carries HARQ, the UCI may be transmitted on the third time domain resource, in this manner, the third time domain resource may not be used for transmitting the first coded bit, or may also be referred to as puncturing PUSCH on the third time domain resource. For another example, when the UCI carries a Scheduling Request (SR)/Channel State Information (CSI), the first coded bit may be transmitted on the third time domain resource, and in this scheme, the third time domain resource may not be used for transmitting the UCI, or may be referred to as puncturing the UCI or puncturing the PUCCH on the third time domain resource.

In the embodiment of the present application, when multiple TOTs of a transport block for cross-slot transmission overlap with a PUCCH carrying UCI, if the transport block performs rate matching in units of TOTs, UCI may be reasonably mapped to a suitable position in a first time domain resource by selecting one or more TOTs (or slots) to send UCI, so that reliability of UCI may be guaranteed, coverage of an uplink data channel may be guaranteed as much as possible, and a requirement on a computational complexity of a terminal device may be reduced as much as possible.

Or, by means of sending one of the UCI and the UL-SCH, coverage of an uplink signal with a higher priority can be preferentially guaranteed, so that the terminal device does not need to perform a complex multiplexing procedure, and implementation complexity is reduced.

According to the above description of the third time domain resource, the third time domain resource may use TOT as a time unit, or may use a time slot as a time unit. The following describes a process of mapping UCI and first coded bits on the third time domain resource by the terminal device with reference to two time units of the third time domain resource.

In the first implementation manner, the TOT is used as a time unit for the third time domain resource.

In this implementation, the third time domain resource may be a plurality of time slots in the n TOTs, for example, the third time domain resource may be the n TOTs. For example, taking fig. 5 as an example, the third time domain resource may include TOT2 to TOT4.

Alternatively, the third time domain resource is one of the n TOTs.

For example, it may be the first TOT of the n TOTs. Taking fig. 5 as an example, the third time domain resource may include TOT 2.

Alternatively, the last TOT of the n TOTs may be considered. Taking fig. 5 as an example, the third time domain resource may include TOT4.

Alternatively, the longest TOT among the n TOTs may be used. Taking fig. 5 as an example, the third time domain resource may include TOT4.

Alternatively, the shortest TOT among the n TOTs may be used. Taking fig. 5 as an example, the third time domain resource may include TOT3.

If the third time domain resource includes multiple TOTs, the terminal device may repeatedly map a second coded bit on each TOT, where the second coded bit is a coded bit obtained by performing channel coding on the UCI. If the third time domain resource includes a TOT, the terminal device may map the second coded bit on the TOT.

Three embodiments of the terminal device transmitting the second coded bit on one TOT are described below. It is to be understood that, if the third time domain resource includes a plurality of TOTs, the terminal device may map the second coded bits on each TOT in the same manner.

In a first embodiment, the terminal device may select a time slot in the TOT to map the second coded bit, for example, may select a first time slot or a last time slot in the TOT or a first time slot overlapping with the second time domain resource, or a last time slot overlapping with the second time domain resource in the TOT, and so on. Thus, the terminal device may map the second coded bits on the time slot. Optionally, the position on the slot where the second coded bit is mapped may be located after the time domain symbol carrying the DMRS. That is, the terminal device may map the second coded bit from a time domain symbol after the time domain symbol carrying the DMRS in the time slot, and map the first coded bit on the remaining symbols in the time slot after the second coded bit is mapped.

For example, taking fig. 5 as an example, assume that the second coded bit is mapped on the first slot in each TOT.

As shown in fig. 7, if the terminal device determines all the TOTs in the TOTs 2 to 4 as the third time domain resource, the terminal device may map the second code bit on the first slot of each of the TOTs 2 to 4, map the second code bit on the first slot of each of the TOTs from one time domain symbol after the time domain symbol carrying the DMRS, and map the first code bit on the remaining symbols of the slot after mapping all the bits of the second code bit.

As shown in fig. 8, if the terminal device determines that a first TOT, that is, TOT2, in TOT2 to TOT4 is used as the third time domain resource, the terminal device may map the second code bit on the first time slot of TOT2, map the second code bit on the time slot from a time domain symbol after the time domain symbol carrying the DMRS, and map the first code bit on the remaining symbols of the time slot after mapping all bits of the second code bit.

In a second embodiment, the terminal device may select multiple time slots in the TOT to map with the second coded bits, for example, all time slots in the TOT may be selected. Thus, the terminal device may map the second coded bits on all time slots of the TOT. Optionally, the position on each slot where the second coded bit is mapped may be located after the time domain symbol carrying the DMRS. That is, the terminal device may map the second coded bits in each slot starting from one time domain symbol after the time domain symbol carrying the DMRS.

Wherein the code bits mapped on each time slot are all the bits of the second code bits. That is, after the terminal device maps all bits of the second coded bits on each slot, the terminal device maps the first coded bits on the remaining bits.

For example, taking fig. 5 as an example, assume that the second coded bits are mapped on all slots in each TOT.

As shown in fig. 9, if the terminal device determines all the TOTs in the TOTs 2 to TOT4 as the third time domain resource, the terminal device may map all bits of the second code bits on each time slot of each of the TOTs 2 to TOT4, and map the first code bits on the remaining symbols of the time slot.

As shown in fig. 10, if the terminal device determines that the first TOT, that is, TOT2, in TOT2 to TOT4 is used as the third time domain resource, the terminal device may map all bits of the second coded bits on each time slot of TOT2, and map the first coded bits on the remaining symbols of the time slot.

Alternatively, the code bits mapped on each slot may be a part of the second code bits. Illustratively, the second coded bit may be mapped over the first K-1 slots of the TOT

Where K is the number of slots included in the TOT, and the rounded value may be an upward rounded value, a downward rounded value, a rounded value, or the like. For example, in rounding-up, the second coded bits may be mapped sequentially from the first slot of the TOT to the first K-1 slots

Bits, second coded bit being mapped on last time slot

One bit. For another example, in rounding-down, the second coded bits may be mapped sequentially from the first time slot of the TOT to the first K-1 time slots

Bits, second coded bit being mapped on last time slot

And (4) a bit.

For example, taking fig. 5 as an example, assume that the terminal device selects all slots in the TOT, the second coded bit comprises 21 bits, and the rounding value is a round-up.

As shown in fig. 11, if the terminal device determines all the TOTs of the TOTs 2 to TOT4 as the third time domain resource, the terminal device may map the second code bit on all the time slots of each of the TOTs 2 to TOT4. Wherein, the 1 st time slot in the TOT2 maps the 1 st to 4 th bits of the second coded bit, the 2 nd time slot maps the 5 nd to 8 th time slots of the second coded bit, the 3 rd time slot maps the 9 th to 12 th time slots of the second coded bit, the 4 th time slot maps the 13 th to 16 th time slots of the second coded bit, the 5th time slot maps the 17 th to 20 th time slots of the second coded bit, and the 6 th time slot maps the 21 st time slot of the second coded bit. The 1 st to 6 th bits, the 7 th to 12 th bits, the 13 th to 18 th bits, and the 19 th to 21 st bits are mapped to the 4 slots in TOT3, respectively. The 1 st to 3 rd bits, the 4 th to 6 th bits, the 7 th to 9 th bits, the 10 th to 12 th bits, the 13 th to 15 th bits, the 16 th to 18 th bits, and the 19 th to 21 th bits are mapped in 7 time slots in the TOT4, respectively.

As shown in fig. 12, if the terminal device determines that a first TOT of the TOTs 2 to 4, that is, the TOT2, is used as the third time domain resource, the terminal device may map the second coded bits on all time slots of the TOT2, and the specific mapping manner may refer to the mapping manner of the TOT2 in fig. 11, which is not described herein again.

In a third embodiment, the terminal device may select a plurality of time slots overlapping with the second time domain resource to map the second coded bits at the TOT, for example, all time slots overlapping with the second time domain resource in the TOT may be selected. Thus, the terminal device may map the second coded bits on all time slots of the TOT that overlap with the second time domain resource. Optionally, the position on each slot to which the second coded bit is mapped may be located after the time domain symbol carrying the DMRS. That is, the terminal device may map the second coded bits in each slot starting from one time domain symbol after the time domain symbol carrying the DMRS.

Wherein the code bits mapped on each time slot are all the bits of the second code bits. That is, after the terminal device has mapped all bits of the second coded bits on each slot, the terminal device maps the first coded bits on the remaining bits.

For example, taking fig. 5 as an example, assume that the second coded bits are mapped on all time slots in each TOT that overlap with the second time domain resource.

As shown in fig. 13, if the terminal device determines all the TOTs in the TOTs 2 to TOTs 4 as the third time domain resource, the terminal device may map the second code bit on each time slot of each of the TOTs 2 to TOTs 4, where the time slot overlaps with the second time domain resource, map the second code bit on each time slot starting from one time domain symbol after the time domain symbol carrying the DMRS, and map the first code bit on the remaining symbols of the time slot after mapping all the bits of the second code bit.

As shown in fig. 14, if the terminal device determines that a first TOT, that is, TOT2, in TOT2 to TOT4 is used as the third time domain resource, the terminal device may map the second coded bit on each time slot of TOT2 that overlaps with the second time domain resource, and the specific mapping manner may refer to the mapping manner of TOT2 in fig. 13, which is not described herein again.

Alternatively, the coded bits mapped on each slot may also be part of the second coded bits. A manner of mapping a part of bits in the third embodiment is similar to that of mapping a part of bits in the second embodiment, and the difference is that K in the second embodiment is the number of time slots in the TOT, and K in the third embodiment is the number of time slots overlapping with the second time domain resource in the TOT, and similar points may be referred to in the related description of the second embodiment, and are not described again here.

For example, taking fig. 5 as an example, it is assumed that the terminal device selects a time slot in which all of the TOTs overlap with the second time domain resource, the second coded bits include 21 bits, and the rounding value is a round-up.

As shown in fig. 15, if the terminal device determines all the TOTs in the TOTs 2 to 4 as the third time domain resource, the terminal device may map the second code bit on all the time slots of each of the TOTs 2 to 4 that overlap with the second time domain resource. Wherein, the 1 st time slot (i.e. the 3 rd time slot) overlapping with the second time domain resource in the TOT2 maps the 1 st to 6 th bits of the second code bit, the 7 nd to 12 th time slots of the second code bit are mapped on the 2 nd time slot (i.e. the 4 th time slot) overlapping with the second time domain resource, the 13 th to 18 th time slots of the second code bit are mapped on the 3 rd time slot (i.e. the 5th time slot) overlapping with the second time domain resource, and the 19 th to 21 th time slots of the second code bit are mapped on the 4 th time slot (i.e. the 6 th time slot) overlapping with the second time domain resource. The 1 st to 6 th bits, the 7 th to 12 th bits, the 13 th to 18 th bits, and the 19 th to 21 st bits are mapped in 4 time slots in the TOT3, respectively. And mapping 1 st to 15 th bits and 16 th to 21 th bits in 2 time slots overlapped with the second time domain resource in the TOT4 respectively.

As shown in fig. 16, if the terminal device determines that a first TOT, that is, TOT2, in TOT2 to TOT4 is used as the third time domain resource, the terminal device may map the second coded bits on all time slots of TOT2 that overlap with the second time domain resource, and the specific mapping manner may refer to the mapping manner of TOT2 in fig. 15, which is not described herein again.

It should be noted that the symbols carrying the DMRS are not shown in fig. 7 to 16 described above, and it should be understood that the symbols carrying the DMRS are located in front of the second coded bits in each slot.

In a second implementation manner, the third time domain resource uses a time slot as a time unit.

In this implementation, the third time domain resource may be R time slots overlapping with the second time domain resource in the n TOTs, where R is an integer greater than 1, where the R time slots may be a part of or all of the time slots overlapping with the second time domain resource in the n TOTs. Thus, the terminal device may map the second coded bits over the R slots. Optionally, the position on each slot where the second coded bit is mapped may be located after the time domain symbol carrying the DMRS. That is, the terminal device may map the second coded bit in the time slot starting from a time domain symbol subsequent to the time domain symbol carrying the DMRS.

All bits of the second coded bits may be mapped on each slot, so that after the terminal device maps all bits of the second coded bits on each slot, the terminal device maps the first coded bits on the remaining symbols of the slot. Or mapping a part of bits of the second coded bits on each slot, so that after the terminal device maps a part of bits of the second coded bits on each slot, mapping the first coded bits on the remaining symbols of the slot. The method for mapping part of bits in the first implementation manner is similar to the method for mapping part of bits in the first implementation manner, except that the second coded bits are mapped on K time slots in the first implementation manner, so that the rounding is performed by taking K as a denominator in the first implementation manner, and the second coded bits are mapped on R time slots in the first implementation manner, so that the rounding is performed by taking R as a denominator in the first implementation manner, and repeated parts are not described again.

Alternatively, the third time domain resource may also be a time slot overlapping with the second time domain resource, for example, the third time domain resource is a time slot overlapping with the second time domain resource in the first of the n TOTs; or, the third time domain resource is a time slot in which the last of the n TOTs overlaps with the second time domain resource. Thus, the terminal device may map the second coded bit on the time slot. Optionally, the position on the slot to which the second coded bit is mapped may be located after the time domain symbol carrying the DMRS. That is, the terminal device may map the second coded bit in the time slot starting from a time domain symbol subsequent to the time domain symbol carrying the DMRS. So that the terminal device maps the first coded bits on the remaining symbols of the slot after mapping all bits of the second coded bits on the slot.

The above introduces various methods for mapping the second coded bit by the terminal device, which method is specifically adopted by the terminal device to map the second coded bit may be defined by a protocol, may also be configured by the network device, and may also be determined by the terminal device itself.

According to the foregoing description, the terminal device maps the second coded bit corresponding to the UCI on the third time domain resource. The second coded bit may be obtained by channel coding the UCI by the terminal device. A method of calculating the second coded bit of the UCI is described below.

The terminal device may determine second coded bits corresponding to the UCI based on the first time length. For example, the terminal device may determine the second coded bit by the following formula, or may also understand that the second coded bit satisfies the following formula:

wherein,

is a first length of time. Q' _ACK For the second coded bit, O _ACK Is the number of bits of HARQ-ACK (i.e. the payload size of HARQ-ACK), L _ACK Cyclic redundancy check (cyclic red) for HARQ-ACKOutstanding check, CRC) number of bits.

For the equalization parameter, it can be considered that the ratio of the code rate of other information (e.g. UL-SCH) on the first transport block to the code rate of UCI, which can be notified by the network device, is a number greater than 0.

TBS, C corresponding to UL-SCH on first transport Block _UL-SCH Number of code blocks included for UL-SCH on first transport Block, K _r Is the number of bits in the r-th code block in the UL-SCH over the first transport block.

The amount of physical resources on the first transport block that can be used to carry UCI,

the number of physical resources that can be used to carry UCI on the ith time domain symbol on the first transport block is described.

It will be appreciated that the above equations are merely exemplary, and that in particular implementations variations of the above equations may be used, or other equations may be used to determine the second coded bits.

The first time length may be the length of the first time domain resource.

Or, the first time length may also be the number of time slots used for uplink transmission in the first time domain resource;

or, the first time length is the length of a first TOT in the first time domain resource;

or, the first time length is the length of the longest/shortest TOT in the first time domain resource;

or the first time length is the length of the third time domain resource;

or the first time length is a time length configured by a high layer;

or, the first time length is the number of time domain symbols used for transmitting the first transport block in one time slot, for example, the first time length is the number L of symbols indicated by the indication information received before step S401;

or, the first time length is the length of one time slot;

or the first time length is the number of time domain symbols overlapped with the second time domain resource in the first time domain resource;

alternatively, the first time length is W times the number of time domain symbols used for transmitting the first transport block in one time slot, for example, the first time length may be L × W, where W is an integer greater than 1, and W may be configured by the network device through higher layer signaling.

Based on the above method for determining the second coded bit, the network device needs to ensure that the calculated second coded bit does not exceed the maximum bit number that can be borne by the third time domain resource. In an implementation manner, the network device may control values of other parameters except for the first time length in the above formula to ensure that the calculated second coded bit does not exceed the maximum bit number that can be carried by the third time domain resource.

Optionally, after determining the second coded bit, the terminal device may determine whether the second coded bit is greater than a maximum bit number that can be carried by the third time domain resource.

If the second coded bit is not greater than the maximum bit number that can be carried by the third time domain resource, the communication method illustrated in fig. 4 can be performed. That is, the terminal device sends the second coded bit and/or the first coded bit on the third time domain resource when the second coded bit is not greater than the maximum bit number that can be carried by the third time domain resource.

If the second coded bit is greater than the maximum bit number that can be carried by the third time domain resource, the terminal device may not send the second coded bit and/or the first coded bit, and the like, and the specific processing manner may be defined by a protocol, may also be an implementation behavior of the terminal device, and may also be a processing manner indicated by the network device, and the like.

The manner in which the terminal device transmits the second coded bits and/or the first coded bits in the third time domain resource is introduced above. Optionally, in the embodiment of the present application, the communication method provided in the embodiment of the present application may be implemented under the condition that a condition of multiplexing the UCI on the PUSCH is satisfied. Illustratively, the condition may be that a time domain length a between the first time domain symbol and the PDSCH is greater than a first value, the first value being related to the terminal device's capabilities. Wherein the first symbol is a first OFDM symbol in PUCCH(s) and PUSCH(s) that overlap in time domain, for example, in the schematic diagram shown in fig. 17, PUCCH and PUSCH overlap in time domain, the first symbol is a first OFDM symbol of PUSCH, and at this time, the time domain length a is a length between the first OFDM symbol of PUSCH and the last OFDM symbol of PDSCH; in the diagram shown in fig. 18, the first symbol is the first OFDM symbol of the PUCCH, and the time domain length a is the length between the first OFDM symbol of the PUCCH and the last OFDM symbol of the PDSCH.

In the embodiment of the present application, rate matching is performed in units of one TOT, and it should be understood that in a specific implementation, rate matching may also be performed in other units, for example, one time slot, multiple time slots, multiple TOTs, and so on. When rate matching is performed in other units, the size of the time domain resource for mapping all bits of the second coded bit may be smaller than the size of the time unit for rate matching, so that UCI may be reasonably mapped at a suitable position in the first time domain resource, and reliability of UCI may be ensured.

In the embodiment of the present application, when multiple TOTs of a transport block for cross-slot transmission overlap with a PUCCH carrying UCI, if the transport block performs rate matching in units of TOTs, UCI may be reasonably mapped to a suitable position in a first time domain resource by selecting one or more TOTs (or slots) to send UCI, so that reliability of UCI may be ensured, requirements on computational complexity of a terminal device may be reduced as much as possible, coverage of an uplink data channel may be ensured as much as possible, and reliability of uplink UCI may be ensured.

Or, by means of sending one of UCI and UL-SCH, coverage of an uplink signal with a higher priority can be preferentially ensured, so that the terminal device does not need to perform a complex multiplexing procedure, and implementation complexity is reduced.

And, through the calculation mode of reasonably selecting the encoding bit of the UCI, the uplink resource is reasonably distributed to the UCI and the uplink data, and the uplink coverage is ensured.

mapping second coding bits corresponding to the UCI on a plurality of time slots of the ith first time unit which are overlapped with the second time domain resources;

18. A method according to claim 12 or 13, wherein the third time domain resource is R time slots of the n first time units that overlap with the second time domain resource, wherein R is an integer greater than 1; or,

the third time domain resource is a time slot in which the last time unit of the n first time units is overlapped with the second time domain resource.

19. The method of claim 18, wherein the UCI is mapped on a qth slot in the third time domain resource in a manner of:

20. The method according to claim 15 or 16 or 17 or 19, characterized in that the position on each slot where the second coded bits are mapped is located after a time domain symbol carrying a demodulation reference signal, DMRS.

21. The method of claim 12, wherein the receiving on the third time domain resource is at least one of: the UCI, or first coded bit, includes:

receiving the UCI on the third time domain resource, the UCI carrying a hybrid automatic repeat request, the third time domain resource not being used for receiving the first coded bit; or

Receiving the first coded bit on the third time domain resource, the third time domain resource not being used for receiving the UCI.

22. The method of any of claims 12-21, wherein second coded bits corresponding to the UCI are associated with a first length of time;

or, the first time length is the length of the third time domain resource;

or, the first time length is a time length configured by a high layer;

or, the first time length is the length of one time slot;

23. A communication device for implementing the method of any one of claims 1-11 or for implementing the method of any one of claims 12-22.

24. A communications apparatus, comprising a processor and a storage medium storing instructions that, when executed by the processor, cause the method of any of claims 1-11 to be implemented, or cause the method of any of claims 12-22 to be implemented.
