Wherein, in the embodiment of the present application, the access network device may be a base station, and the solution provided in the embodiment of the present application is schematically described.

In order to facilitate the understanding of the relevant content of the embodiment of the present application, some knowledge required for the solution of the present application will be introduced below.

1. Symbol

Symbols can also be called time-domain symbols, including but not limited to orthogonal frequency division multiplexing (OFDM) symbols, sparse code division multiple access (sparse code multiplexing access, SCMA) symbols, filtered orthogonal frequency Division multiplexing (filtered orthogonal frequency division multiplexing, F-OFDM) symbols, non-orthogonal multiple access (non-orthogonal multiple access, NOMA) symbols can be determined according to actual conditions, and will not be described here.

Two, time slot (slot)

In long term evolution (LTE), 1 slot occupies consecutive 6 or 7 OFDM symbols in the time domain, etc., and in NR, 1 slot occupies 14 consecutive OFDM symbols in the time domain (regular cyclic prefix) or 12 consecutive OFDM symbols (extended cyclic prefix), etc.

3. High-level signaling

The high-level signaling generally refers to the signaling sent by the high-level protocol layer, and the high-level protocol layer is at least one protocol layer above the physical layer. Wherein, the high-level protocol layer may specifically include at least one of the following protocol layers: medium access control (medium access control, MAC) layer, radio link control (radio link control, RLC) layer, packet data convergence protocol (packet data convergence) protocol, PDCP) layer, radio resource control (radio resource control, RRC) layer and non-access stratum (non access stratum, NAS).

4. Repeated sending of Type A and Type B

The NR protocol supports a maximum of 16 repeated transmissions of the physical uplink shared channel (PUSCH), and a maximum of 8 repeated transmissions of the physical uplink control channel (PUCCH). Specifically, the current NR protocol supports repeated transmission of Type A for PUCCH, and supports repeated transmission of Type A and Type B for PUSCH.

1. Repeated transmission of Type A refers to: K repetitions need to occupy consecutive K time slots, perform 1 repeated transmission on each time slot, and satisfy the time occupied by repeated transmissions on each time slot The field start symbol S and the symbol number L are identical. For example, please refer to FIG. 2, which is a schematic diagram of repeated sending of Type A provided by the embodiment of the present application. As shown in Figure 2, it is assumed that 4 repeated transmissions are configured for PUSCH or PUCCH (that is, repeated transmissions are performed in slot1~slot4), and each repeated transmission occupies the first time domain symbol in a slot (that is, symbol index 0 corresponding symbol) to the 10th time-domain symbol (that is, the symbol corresponding to symbol index 9), then it is necessary to satisfy the repeated transmission of each time slot in the first time-domain symbol to the 10th time-domain symbol of each time slot on the symbol.

2. The repeated transmission of Type B refers to: according to the initial time-domain symbol position S of the first repeated transmission, according to the number L of time-domain symbols that need to be occupied for each repetition, it is performed on multiple consecutive time-domain symbols Repeated transmission, that is, starting from the Sth time domain symbol of the current time slot, the subsequent K*L time domain symbols (may be extended to other time slots) are used for K times of repeated transmission. The actual number of repetitions sent may be more than K times, because if one of the resources crosses the boundary of the time slot, it is divided into two resources. For example, please refer to FIG. 3, which is a schematic diagram of repeated transmission of Type B provided by the embodiment of the present application. As shown in Figure 3:

Case1: When 2 repeated transmissions are configured and each repeated transmission occupies 4 time-domain symbols, 2 repeated transmissions will be completed on 8 consecutive time-domain symbols.

Case2: When 4 repeated transmissions are configured and each repeated transmission occupies 4 time-domain symbols, since the third resource crosses the time slot boundary, 5 repeated transmissions are completed on 16 consecutive time-domain symbols.

Case3: When one transmission is configured and a single transmission occupies 14 time-domain symbols across time slot boundaries, 2 repeated transmissions will be performed on consecutive 14 time-domain symbols.

Among them, whether it is repeated transmission of type A or type B, when the time-domain resource of each repetition does not meet the transmission requirements (for example, downlink symbols are encountered in the consecutive L time-domain symbols starting from the S-th time-domain symbol, Or when encountering high-priority data to be transmitted on symbols), the current transmission is canceled, so that the actual number of repeated transmissions will be less than the expected number of repeated transmissions configured by the access network device.

3. The indication methods of the start symbol S and the number of symbols L include the following two methods:

The first way: scheduling based on grant (GB). The access network device may send a PDCCH to the terminal device, where the PDCCH is used to schedule uplink data PUSCH transmission, that is, the PDCCH may be used to indicate time domain resources for PUSCH transmission. Specifically, the steps of indicating time-domain resources based on grant (Grant based, GB) scheduling are as follows:

Step 1: The terminal device determines a time-domain resource table. The time-domain resource table may be a table predefined by the protocol or one of the tables configured by the access network device for the terminal device through high-layer signaling. Each row in the time domain resource table indicates a start symbol S and the number L of symbols.

Step 2: The terminal device receives the PDCCH from the access network device, the PDCCH carries downlink control information (downlink control information, DCI), and the DCI contains X bits, which are used to indicate a row in the time domain resource table, and then The start symbol S and the number of symbols L of the time-domain resource can be determined.

The second way: configure authorized scheduling (configured grant). Among them, the configuration authorization scheduling includes two types, which are authorization scheduling type 1 and authorization scheduling type 2 respectively. The scheduling method of authorized scheduling type 2 is similar to that of GB scheduling, and will not be repeated here. For authorized scheduling type 1, the position of time domain resources occupied by data transmission is configured through high-level signaling instead of sending PDCCH configuration. The following describes the steps for configuring authorized scheduling to indicate time domain resources:

Step 1: The terminal device determines a time-domain resource table, and the time-domain resource table may be a table predefined by the protocol or one of tables configured by a high layer. Each row in the time domain resource table indicates a start symbol S and the number L of symbols.

Step 2: The terminal device receives high-level signaling from the access network device, the high-level signaling indicates a certain row in the time domain resource table, and then determines the start symbol S and the number of symbols L of the time domain resource.

For example, please refer to FIG. 4 , which is a schematic diagram of a time-domain resource provided by an embodiment of the present application. As shown in Figure 4, assuming that the start symbol S=2 and the number of symbols L=4 are determined based on the above-mentioned GB scheduling or configuration grant scheduling, it means that the time domain resource of PUSCH is the third symbol of the 14 symbols in a time slot (that is, the symbol corresponding to symbol index 2) to the sixth symbol (that is, the symbol corresponding to symbol index 5).

4. Period P and time domain offset value

It can be understood that, in addition to configuring the start symbol S and the number of symbols L through high-level signaling, the configuration of grant scheduling can also configure the time domain offset value and period P (also called transmission period or PUSCH transmission period) through high-level signaling. ). Wherein, the time domain offset value is used to determine from which time slot data can be sent, that is, the starting time slot. Period P can be understood as determining the start symbol S of the time-domain resource, the number of symbols L, the start time slot, and the number of time slots. This resource appears periodically and can be used for data transmission. For example, please refer to FIG. 5 , which is a schematic diagram of a period P provided in an embodiment of the present application. As shown in Figure 5, assuming that 4 time slots are determined for data transmission based on the repeated transmission method of Type A, there will be 4 time slots for data transmission in each period P (as shown in Figure 5 slot1~slot4, slot7~slot10).

Among them, the hybrid automatic retransmission request process number (HPN) used by the data transmitted in the same cycle is the same, and the HPN between different cycles can be different, that is, the HPN is different from the current data The cycle is related, and the HPN is related to which pipeline is used to process the data, and the problem of merging with the unsuccessful data that used the same HPN before.

5. There are two ways to indicate the number of repetitions K:

The first method: each row in the time domain resource table mentioned above may contain a repetition number K, and when a certain row in the time domain resource table is indicated through the PDCCH or high-layer signaling, the repetition number K may be determined at the same time.

The second type: if there is no repetition number K in the time-domain resource table, then the repetition number K can be a parameter configured through high-level signaling. If the high-level signaling does not configure the repetition number parameter, then the default K=1 or the default K is default values, etc.

5. Enhanced Type A repeated sending

Considering the coverage requirement (that is, to improve the uplink transmission performance), the above-mentioned repeated transmission of type A can be enhanced (for the convenience of description, it can also be described as the enhanced repeated transmission of type A), that is, the canceled transmission is not counted in the repeated transmission Within the number of times, continue to look backward for resources that can be used for transmission until the requirement for the number of repetitions is met. Specifically, the repeated transmission method of the enhanced type A is: instead of counting the number of repetitions based on consecutive time slots, the number of repetitions is counted based on the time slots that can actually be used for uplink data transmission. In this embodiment of the present application, a time slot that can actually be used for uplink data transmission may be described as an available time slot (available slot). That is to say, after the number of repetitions K, the start symbol S, and the number of symbols L are determined, K available time slots can be found in sequence from front to back in the time domain. Among them, the available time slot is defined by excluding the unavailable slot (unavailable slot), wherein the unavailable slot can be defined as: starting from the start symbol S in these time slots, the consecutive L symbols contain symbol.

For example, please refer to FIG. 6, which is a schematic diagram of the enhanced Type A repeated transmission provided by the embodiment of the present application. Assume that based on the Type A repeated transmission method, 4 time slots are determined for data transmission (slot1~slot4 shown in Figure 6), but 3 of them are unusable time slots (slot2~slots shown in the shadow of Figure 6). slot4). Therefore, these three time slots are not counted, and the next time slot is found until four available time slots (slot1, slot5-slot7 as shown in Figure 6) are determined to transmit data, so as to ensure the coverage of uplink data .

Among them, when the enhanced type A repeated transmission method is used, in order to meet the requirements for the number of repeated transmissions, the available time slots for repeated transmissions may cause time-domain resource conflicts due to cross-period boundaries, affecting access network equipment and Normal communication between end devices. Schematically, please refer to FIG. 7. FIG. 7 is another schematic diagram of the enhanced Type A repeated transmission provided by the embodiment of the present application. As shown in Figure 7, it is assumed that the first 4 time slots of each cycle are used to transmit data based on the Type A repeated transmission method, where, due to the different unavailable time slots in each cycle, for example, in the first row of Figure 7, The third time slot in the first cycle is an unavailable time slot, and the first three time slots in the second cycle are all unavailable time slots, resulting in the data that can be used for data determined based on the enhanced Type A repeated transmission method. The time slots for transmission are shown in the second row. Among them, it can be seen from the second line in Figure 7 that in order to meet the requirements for the number of repeated transmissions, the resources repeated in the fourth cycle in the second cycle will be extended to the third cycle, which is different from the resources used in the first cycle in the third cycle. Resources for data transmission conflict, therefore, it will affect the normal communication between the access network device and the terminal device.

Based on this, an embodiment of the present application proposes a communication method, which can improve communication reliability. The communication method and communication device provided by this application are introduced in detail below:

Please refer to FIG. 8 . FIG. 8 is a schematic flowchart of a communication method provided by an embodiment of the present application. As shown in FIG. 8, the communication method includes the following steps S801-S802. The method execution body shown in FIG. 8 may be a terminal device, or the method execution body shown in FIG. 8 may also be a chip in the terminal device. This is not limited. For convenience of description, a terminal device will be used as an example for description below.

S801. Determine a repetition number parameter M of the physical uplink shared channel PUSCH.

In some feasible implementation manners, during uplink transmission, in order to improve the performance of uplink transmission, the terminal device may implement communication enhancement by means of repeated transmission. Specifically, the terminal device may determine a parameter M of repetition times of the physical uplink shared channel PUSCH. Wherein, the determination of the repetition number parameter M of the PUSCH by the terminal device can be understood as: the terminal device receives indication information from the access network device, and the indication information includes the repetition number parameter M, that is, the indication information indicates the repetition number parameter M. Wherein, the PUSCH involved in the embodiment of the present application may be understood as a PUSCH scheduled based on a configuration grant scheduling type. It is understandable that the indication information may also include one or more of information such as the start symbol S, the number of symbols L, the period P, and the time domain offset value, that is, the indication information may also be used to indicate the start symbol S, the symbol One or more of information such as the number L, the period P, and the time domain offset value are not limited here. Therefore, based on the indication information received from the access network device, the terminal device can determine one or more of the information configured to send the first PUSCH, such as the start symbol S, the number of symbols L, the period P, and the time domain offset value. indivual.

S802. Determine K available time slots for sending the first PUSCH.

In some feasible implementation manners, K available time slots for sending the first PUSCH are determined, the K available time slots are in the first PUSCH transmission period, and K is less than M. That is to say, the time slots outside the first PUSCH transmission period are unavailable time slots. In this embodiment of the present application, an unavailable time slot may be understood as a time slot that is not used for sending the first PUSCH, but can be used for sending other data/information (that is, other data/information except the first PUSCH). For example, other data/information may be synchronization data block, downlink data, PDCCH, other PUSCH, PUCCH, etc., which is not limited here.

Wherein, the time-domain resource determined by the start symbol S and the number of symbols L in each time slot is the first time-domain resource. In the embodiment of the present application, in the same period, among the K available time slots in the first available time slot and the last available time slot in X consecutive time slots, when the time slot that satisfies the first condition is unavailable Gap. Wherein, the first time-domain resource included in the time slot satisfying the first condition (that is, the unavailable time slot) overlaps with at least one of the following symbols (or positions described as symbols):

1. The downlink symbols configured by semi-static signaling, such as the downlink symbols indicated by the tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated parameters, are not limited here.

2. The symbols used for synchronous data block transmission, such as the symbols indicated by the SSB configuration parameter, are not limited here.

8. The symbol used to repeatedly send the PUCCH, such as the symbol indicated by the Semi-static PUCCH with repetition parameter, is not limited here.

9. Symbols configured based on high-level signaling that cannot be used for uplink transmission, such as invalid symbols indicated by the invalidSymbolPattern parameter, are not limited here. Wherein, the specific indication manner may be to indicate whether each symbol in one or two time slots is an illegal symbol by means of a symbol-level bitmap (bitmap). Wherein, a bit value of 1 in the symbol-level bitmap indicates that the corresponding symbol is an illegal symbol, a bit value of 0 indicates that the corresponding symbol is a legal symbol, or a bit value of 1 in the symbol-level bitmap indicates that the corresponding The symbol is a legal symbol, and a bit value of 0 indicates that the corresponding symbol is an illegal symbol, and there is no limitation here. For example, take a symbol-level bitmap with a length of 14 bits as an example for schematic illustration, that is, take a symbol-level bitmap to indicate whether each symbol in a time slot is an illegal symbol for example. . Wherein, assuming that the symbol-level bitmap is 10000100000000, where 1 indicates that the corresponding symbol is an illegal symbol, and 0 indicates that the corresponding symbol is a legal symbol, then according to the symbol-level bitmap, it can be determined that The first symbol (that is, the symbol with symbol index 0) and the sixth symbol (that is, the symbol with symbol index 5) of are illegal symbols. Optionally, the access network device may also send a parameter (such as a time slot-level bitmap) to the terminal device to indicate which time slots in a cycle can determine illegal symbols based on the above symbol-level bitmap, and which Slots are not based on the above symbol-level bitmap to determine illegal symbols. Wherein, a bit value of 1 in the slot-level bitmap indicates that the corresponding time slot can determine an illegal symbol based on the above-mentioned symbol-level bitmap, and a bit value of 0 indicates that the corresponding time slot is not based on the above-mentioned symbol-level bits Figure to determine the illegal symbol, or, the bit value of the slot-level bitmap is 1, indicating that the corresponding slot can determine the illegal symbol based on the bitmap of the above symbol level, and the bit value is 0, indicating that the corresponding slot is not based on The above-mentioned symbol-level bitmap determines illegal symbols, and there is no limitation here. For example, assuming that the period P=6 (that is, a period includes 6 time slots), the bitmap of the time slot level is 10000, therefore, it can be determined that the first time slot in the period can be based on the above symbol level The bitmap of determines whether each symbol in the slot is an illegal symbol. Optionally, if the slot-level bitmap is not configured, it can be agreed by default that odd-numbered slots in a cycle can determine illegal symbols based on the above-mentioned symbol-level bitmap, and even-numbered slots cannot Illegal symbols are determined based on the above symbol-level bitmap, or, by default, the even-numbered time slots in a cycle can be determined based on the above-mentioned symbol-level bitmap, and the odd-numbered time slots cannot be based on the above-mentioned Symbol-level bitmaps identify illegal symbols.

For another example, symbols configured to receive PDCCH, PDSCH or channel state information-reference signals (channel state information-reference signals, CSI-RS) through high layer signaling are not limited here.

That is to say, the terminal device can start from the first time slot in the first PUSCH transmission cycle and sequentially determine the first time domain resources included in each time slot (that is, determined by the start symbol S and the symbol length L) along the time sequence. Whether there are one or more symbols in the time domain resource) overlap with the above at least one kind of symbol (or position described as a symbol), wherein, if the first time domain resource of any time slot in the first PUSCH transmission period overlaps with the above If at least one symbol overlaps, it is determined that the time slot is an unavailable time slot, and if there is no overlap between the first time domain resource of a certain time slot in the first PUSCH transmission cycle and each of the above symbols, it is determined that the time slot is an available time slot Gap. Understandably, if only K (K<M) available time slots are determined when traversing to the last time slot in the first PUSCH transmission cycle, then the K available time slots may be determined as used for sending the first PUSCH available time slots. That is to say, the time slots other than the first PUSCH transmission period are all available time slots that cannot be used to send the first PUSCH. Therefore, the K available time slots determined based on the method of the embodiment of the present application may be less than Based on the repetition times parameter M indicated by the access network device.

If the time slot is an unavailable time slot, continue to look backward until you find 4 available time slots, as shown in the second row in Figure 9, among the 4 available time slots included in the first cycle, the first available time slot There are 5 time slots up to the last available time slot, of which the second time slot is an unavailable time slot. Since the first 3 time slots in the second cycle are unavailable time slots, 3 available time slots can be determined sequentially from the 4th time slot in the second cycle, and when 3 available time slots are found , since the next time slot will exceed the period boundary, only 3 available time slots can be determined.
