Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication method and a communication device. Background Art

[0002] In a time division duplexing (TDD) system, usually the downlink (DL) occupies the main time resources, which results in poor coverage and large latency of the uplink (UL). To address the problems of uplink coverage and latency in the TDD system, a subband full duplex (SBFD) scheme is proposed. In the SBFD scheme, a carrier is divided into multiple subbands, and the transmission directions of different subbands can be different. Thus, the base station can simultaneously perform downlink transmission on the downlink subband and uplink transmission on the uplink subband, which is equivalent to increasing the available time-frequency resources of the uplink, thereby improving uplink coverage and reducing uplink latency.

[0003] Currently, the new radio (NR) physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) supports repeated transmission in the time domain. Or rather, the transmission block (TB) carried by the PDSCH or PUSCH can be repeatedly transmitted at multiple transmission opportunities. In the SBFD scenario, if the PDSCH or PUSCH is repeatedly transmitted, it is very likely that during a round of repeated transmission, some repeated transmissions are transmitted in the SBFD slot, while some other repeated transmissions are transmitted in the non-SBFD slot. In the SBFD slot, since the signal power within the subband will leak into the adjacent subbands, it may cause interference between the uplink and the downlink, which is called cross link interference (CLI). Due to the existence of CLI, the channel quality in the SBFD slot may be worse than that in the non-SBFD slot. During the repeated transmission of the PDSCH or PUSCH, the modulation and coding scheme (MCS) used remains unchanged. Then, there may be a problem that the MCS used for a certain transmission does not match the channel quality corresponding to this transmission, reducing the transmission performance. Summary of the Invention

[0004] To solve the above technical problems, embodiments of this application provide a communication method and a communication device for improving transmission performance.

[0005] In a first aspect, a communication method is provided. The method may be executed by a second device. The second device is, for example, a network device, or another device including network device functions, or a chip system (or, chip) or other functional modules that can implement the functions of a network device, and the chip system or functional modules are, for example, disposed in a network device. Optionally, the network device is an access network device. Optionally, the access network device is, for example, a base station, or another device within the access network.

[0006] The method includes:

[0007] Sending first information, where the first information is used to schedule a first transport block. Among them, the first information is further used to indicate that the first transport block is transmitted on a first type of time unit using a first modulation and coding scheme, and is further used to indicate that the first transport block is transmitted on a second type of time unit using a second modulation and coding scheme. Wherein, the first type of time unit is a non-SBFD type of time unit, the second type of time unit is an SBFD type of time unit, or the first type of time unit is an SBFD type of time unit, and the second type of time unit is a non-SBFD type of time unit. Wherein, the first modulation and coding scheme includes a first modulation scheme and a first coding rate, and the second modulation and coding scheme includes a second modulation scheme and a second coding rate.

[0008] The first information in the embodiments of this application may indicate the first modulation and coding scheme corresponding to the first type of time unit, or may also indicate the second modulation and coding scheme corresponding to the second type of time unit. That is to say, the embodiments of this application can respectively indicate the modulation and coding schemes for different types of time units, thereby providing the possibility of using different modulation and coding schemes for different types of time units. For example, if the channel quality of different types of time units is different, the modulation and coding schemes indicated for different types of time units may be different, so that the modulation and coding schemes applied to the transport blocks carried by the corresponding time units can be adapted to the channel quality to improve the transmission performance.

[0009] In an alternative embodiment, the first information is used to indicate the transmission resources of the first transport block. The transmission resources include a first resource and a second resource. The time units included in the first resource are time units of the first type, and the time units included in the second resource are time units of the second type. Wherein, the first information includes second information and third information, and includes at least one of fourth information or fifth information. The second information includes the time-domain resource information of the first resource, the third information includes the frequency-domain resource information of the first resource, the fourth information includes the time-domain resource information of the second resource, and the fifth information includes the frequency-domain resource information of the second resource. In the embodiment of the present application, the second information and the third information can indicate the transmission resources corresponding to the time units of the first type, and in addition, the fourth information and / or the fifth information can indicate the transmission resources corresponding to the time units of the second type. Thus, the separate indication of the resources corresponding to the two types of time units is realized, which is equivalent to implicitly indicating the coding code rates respectively corresponding to the two types of time units. The coding code rates corresponding to the two types of time units can be separately indicated, so that the coding code rates corresponding to the two types of time units can be separately adjusted or set, and different possibilities are provided for the coding code rates corresponding to the two types of time units.

[0010] In an alternative embodiment, the first coding code rate is the same as the second coding code rate; or, the first coding code rate is different from the second coding code rate.

[0011] In an alternative embodiment, the first modulation scheme is the same as the second modulation scheme; or, the first modulation scheme is different from the second modulation scheme.

[0012] For example, if the channel qualities of different types of time units are different, the first modulation and coding scheme and the second modulation and coding scheme can be different, so that the modulation and coding scheme applied to the transport block carried by the corresponding time unit can adapt to the channel quality to improve the transmission performance. To make the first modulation and coding scheme different from the second modulation and coding scheme, it is possible to only make the first modulation scheme different from the second modulation scheme, while the first coding code rate and the second coding code rate can be the same; or it is possible to only make the first coding code rate different from the second coding code rate, while the first modulation scheme and the second modulation scheme can be the same; or it is possible to make the first modulation scheme different from the second modulation scheme and the first coding code rate different from the second coding code rate, which is more flexible.

[0013] In an alternative embodiment, the first information includes sixth information and seventh information. The sixth information is used to indicate the first modulation and coding scheme, and the seventh information is used to indicate the second modulation and coding scheme. In the embodiments of the present application, the modulation schemes corresponding to different types of time units can be indicated separately, so that the modulation schemes corresponding to the two types of time units can be modulated or set separately, and different possibilities are provided for the modulation schemes corresponding to the two types of time units.

[0014] In an alternative embodiment, the seventh information is used to indicate the second modulation and coding scheme, including:

[0015] The seventh information includes information on the second modulation scheme, or the seventh information includes information on the modulation order corresponding to the second modulation scheme; or, the seventh information includes the change amount of the second modulation scheme relative to the first modulation scheme; or, the seventh information includes the change amount of the second modulation order relative to the first modulation order, where the first modulation order is the modulation order corresponding to the first modulation scheme, and the second modulation order is the modulation order corresponding to the second modulation scheme. The seventh information can directly indicate the second modulation and coding scheme or the corresponding modulation order. The receiving end (such as the first device) can directly determine the second modulation and coding scheme or the corresponding modulation order according to the seventh information without relying on other information, which helps to simplify the implementation of the receiving end. Alternatively, the seventh information can also indicate the change amount (or called the difference amount or adjustment amount, etc.) of the second modulation scheme (or modulation order) relative to the first modulation scheme (or modulation order). Then the receiving end can combine the first modulation scheme (or modulation order) to determine the second modulation scheme (or modulation order). When indicating the change amount, the number of bits required may be less than that for indicating the complete second modulation scheme, thereby reducing the overhead of the seventh information.

[0016] In an alternative embodiment, the seventh information includes the change amount of the second modulation scheme relative to the first modulation scheme, where the value of the seventh information is a first value, used to indicate that the second modulation scheme is the modulation scheme obtained by increasing or decreasing the modulation order corresponding to the first modulation scheme by M levels, and M is an integer greater than or equal to 0. One way for the seventh information to indicate the change amount is that the seventh information can indicate the change amount of the modulation order. Thus, the receiving end can determine the second modulation scheme (or modulation order) according to the first modulation scheme (or modulation order) and the seventh information. Alternatively, the seventh information can also indicate the change amount in other ways, which is not limited herein.

[0017] In an alternative embodiment, the first information is further used to schedule a second transport block, and the second transport block and the first transport block are carried on the same physical channel. Wherein, the time-domain resources used by the second transport block for transmission on the time units of the first type are indicated by second information in the first information, and the frequency-domain resources used by the second transport block for transmission on the time units of the first type are indicated by third information in the first information; the time-domain resources used by the second transport block for transmission on the time units of the second type are indicated by fourth information in the first information, and / or the frequency-domain resources used by the second transport block for transmission on the time units of the second type are indicated by fifth information in the first information; wherein, the second information includes information on the time-domain resources of a first resource, the third information includes information on the frequency-domain resources of the first resource, the fourth information includes information on the time-domain resources of a second resource, the fifth information includes information on the frequency-domain resources of the second resource, and the first resource and the second resource belong to the transmission resources of the first transport block. The time-domain resources and frequency-domain resources occupied by the first transport block and the second transport block may be the same, and the spatial-domain resources occupied may be different. Then, the time-frequency resources used by the second transport block can be indicated by the information for indicating the time-frequency resources of the first transport block, without the need to additionally add information for indicating the time-frequency resources for the second transport block in the first information, which is beneficial to saving the overhead of the first information.

[0018] In an alternative embodiment, the first information is further used to schedule a second transport block, and the second transport block and the first transport block are carried on the same physical channel. Wherein, the modulation scheme and coding rate used by the second transport block for transmission on the time units of the first type are indicated by eighth information in the first information, and the eighth information is used to indicate a third modulation and coding scheme used by the second transport block for transmission on the time units of the first type; the modulation order used by the second transport block for transmission on the time units of the second type is indicated by seventh information in the first information, and the seventh information is used to indicate the second modulation and coding scheme.

[0019] In an alternative embodiment, the first information is further used to schedule a second transport block, and the second transport block and the first transport block are carried on the same physical channel. Among them, the modulation scheme and coding rate used for transmitting the second transport block on the first type of time unit are indicated by the eighth information in the first information, and the eighth information is used to indicate that the second transport block uses a third modulation and coding scheme for transmission on the first type of time unit. The modulation scheme and coding rate used for transmitting the second transport block on the second type of time unit are indicated by the ninth information in the first information, and the ninth information is used to indicate that the second transport block uses a fourth modulation and coding scheme for transmission on the second type of time unit. The modulation order (or modulation scheme) used for transmitting the second transport block on the second type of time unit can be indicated by the seventh information included in the first information to save the transmission overhead of the first information; alternatively, a ninth information can also be added to the first information, and the ninth information is used to indicate the modulation order (or modulation scheme) used for transmitting the second transport block on the second type of time unit, or to indicate the modulation and coding scheme used for transmitting the second transport block on the second type of time unit. Thus, the indication of the second transport block and the first transport block is separated, ensuring the flexibility of implementation of the first device and the second device.

[0020] In an alternative embodiment, the first information is included in DCI or RRC signaling.

[0021] In an alternative embodiment, a tenth information is sent to the second device, and the tenth information is used to indicate that the first type of time unit is a non-SBFD type of time unit and to indicate that the second type of time unit is an SBFD type of time unit, or the tenth information is used to indicate that the first type of time unit is an SBFD type of time unit and to indicate that the second type of time unit is a non-SBFD type of time unit. The tenth information is, for example, included in the first information, or can also be included in other information sent by the network device, or can also be included in a newly defined message in the embodiments of the present application, and this message is used to indicate the type of time unit. Alternatively, the second device does not have to send the tenth information, and what types the two types of time units are can also be predefined by the protocol or can be preconfigured in the first device and the second device.

[0022] In an alternative embodiment, the first type is the type of time unit where the first valid transmission opportunity is located in the repeated transmission of the first transmission block or the second transmission block. In this way, two types of time units can be determined without relying on other information (such as information sent by the second device, or predefined or preconfigured information, etc.), which helps to save signaling overhead caused by the second device sending information and also helps to save storage space consumed by storing predefined or preconfigured information.

[0073] The network device in the embodiment of the present application includes, for example, an access network device and / or a core network device. The access network device is a device with wireless transceiver functions and is used to communicate with the terminal device.

The RU may be included in a radio frequency device or a radio frequency unit, such as being included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0079] A PDSCH or PUSCH can carry one or two transport blocks (TBs), and each TB can be transmitted over the air interface after independent channel coding, modulation, and other processing.

[0080] The principle of channel coding is to add redundant information to the original data. This redundant information is related to the original data, and the receiving end can check and correct errors generated during the transmission process based on this correlation, thereby combating interference during the transmission process. Among them, the transmitting end performs channel coding on the data to be transmitted, and the receiving end performs channel decoding on the received data. In NR, both PDSCH and PUSCH use low density parity check (LDPC) codes for channel coding. Generally speaking, the more redundant information added by channel coding, the lower the channel coding rate, and the better its error detection and correction capabilities; conversely, the higher the channel coding rate, the worse its error detection and correction capabilities. Among them, the channel coding rate can be defined as the value of the number of bits of the original information divided by the number of coded bits transmitted.

[0081] Modulation refers to the process in which the transmitting end transforms the signal to be transmitted into a form suitable for the channel characteristics by adjusting the amplitude, frequency, phase, etc. of the signal; correspondingly, the receiving end needs to restore the modulated signal to the original signal, and this process is called demodulation. Currently, the modulation technology adopted by NR PDSCH and NR PUSCH is quadrature amplitude modulation (QAM), and QAM is a technology that combines phase modulation and amplitude modulation. The QAM modulation schemes supported by NR PDSCH and PUSCH and the corresponding modulation orders are shown in Tables 1-1 and 1-2. Different modulation schemes can modulate different numbers of bits onto one modulation symbol, which is called the modulation order. In addition, one modulation symbol is mapped to one resource element (RE), and one RE occupies one orthogonal frequency division multiplexing (OFDM) symbol in the time domain and one subcarrier in the frequency domain. Similarly, the higher the modulation order, the higher the transmission efficiency. However, the higher the modulation order, the worse the transmission robustness and the more prone to errors.

[0086] Table 1-2 takes the NR PUSCH with discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) waveform and OFDM waveform as examples. The "-" in Table 1-2 indicates none.

[0087] Generally speaking, the worse the channel quality, the lower the modulation order and channel coding rate should be; the better the channel quality, the higher the modulation order and channel coding rate should be. NR follows the mechanism of LTE, jointly designs the modulation scheme and channel coding rate, introduces the concept of MCS, and predefines multiple MCS tables for different scenarios. Exemplarily, an MCS table is shown in Table 1-3. It can be seen that the larger the MCS index, the higher the corresponding modulation order or modulation coding, and the higher the corresponding spectral efficiency.

[0091] In a TDD system, usually the DL occupies the main time resources, which causes the coverage imbalance between DL and UL. Please refer to Figure 1 , Figure 1 which is a schematic diagram of a TDD system. Compared with a frequency division duplexing (FDD) system, the uplink coverage of a TDD system is poor and the delay is large. To address the uplink coverage and delay problems in a TDD system, the SBFD scheme is proposed. In the SBFD scheme, a carrier is divided into multiple subbands, and the transmission directions of different subbands can be different, thereby improving the uplink coverage. Please refer to Figure 2A and Figure 2B , Figure 2A and Figure 2B which show two schematic diagrams of the SBFD scheme. Figure 2A is a typical SBFD scheme. In this scheme, a carrier is divided into three subbands, the middle subband is used for uplink transmission, and the upper and lower subbands are used for downlink transmission. Figure 2BAs another typical SBFD solution, in this solution, a carrier is divided into two sub-bands. The upper sub-band is used for downlink transmission, and the lower sub-band is used for uplink transmission. In the SBFD solution, transmission and reception can be performed simultaneously on one OFDM symbol (or time slot). It can be considered that in SBFD, different frequency domain resources (such as sub-bands) are used for uplink and downlink.

[0092] Since the signal power within a sub-band will leak into adjacent sub-bands, it will cause interference between the uplink and the downlink, which is called CLI. According to the source of interference, cross-link interference includes two major categories. The first is the cross-link interference between UEs, mainly referring to the interference caused by the uplink signal sent by a UE in this cell to the downlink signal received by another UE in this cell or an adjacent cell; the second is the cross-link interference between base stations, mainly referring to the interference caused by the downlink signal sent by a certain base station to the uplink signal received by another base station. Figure 3 Fig. is a schematic diagram of CLI. In Figure 3 , the uplink signal of UE0 will cause interference to both the downlink signals of UE1 and UE2; the downlink signals sent by base station 1 to UE1 and UE2 will also cause interference to the uplink signal received by base station 0 from UE0. Among them, Figure 3 the dashed arrows in Fig. represent interference, and the solid arrows represent the signal transmission direction.

[0093] Currently, NR PDSCH or PUSCH supports repeated transmission in the time domain. Alternatively, the TB carried by PDSCH or PUSCH can be repeated in multiple transmission opportunities. In the SBFD scenario, if PDSCH or PUSCH is repeatedly transmitted, it is very likely that during a round of repeated transmission, some of the repeated transmissions are performed on SBFD time slots (or, OFDM symbols), while some of the repeated transmissions are performed on non-SBFD time slots (or, OFDM symbols). On SBFD time slots, due to the existence of CLI, the channel quality on SBFD time slots may be worse than that on non-SBFD time slots. During the repeated transmission of PDSCH or PUSCH, the MCS used remains unchanged. Then, there may be a problem that the MCS used for a certain transmission does not match the channel quality corresponding to this transmission, reducing the transmission performance.

[0094] In view of this, the first information in the embodiments of the present application may indicate a first modulation and coding scheme corresponding to a first type of time unit, or may also indicate a second modulation and coding scheme corresponding to a second type of time unit. That is to say, the embodiments of the present application can respectively indicate modulation and coding schemes for different types of time units, thereby providing the possibility of using different modulation and coding schemes for different types of time units. For example, if the channel quality of different types of time units is different, the modulation and coding schemes indicated for different types of time units can be different, so that the modulation and coding schemes applied to the transport blocks carried by the corresponding time units can adapt to the channel quality to improve the transmission performance.

[0095] The technical solutions provided by the embodiments of the present application can be applied to the fourth-generation mobile communication technology (the 4th generation, 4G) system, such as the LTE system, or can be applied to the fifth-generation mobile communication technology (the 5th generation, 5G) system, such as the NR system, or can also be applied to the next-generation mobile communication system or other similar communication systems, such as the sixth-generation mobile communication technology (the 6th generation, 6G) system, etc., without specific limitation. In addition, the technical solutions provided by the embodiments of the present application can be applied to the D2D scenario, such as the NR-D2D scenario, etc., or applied to the V2X scenario, such as the NR-V2X scenario, etc. For example, the embodiments of the present application can be used in fields such as factory manufacturing, whole-house intelligence, intelligent driving, assisted driving, intelligent connected vehicles, or indoor commercial scenarios.

[0096] Exemplarily, Figure 4 shows a communication network architecture to which the embodiments of the present application are applied. As Figure 4 shown, PDSCH and / or PUSCH, etc. can be transmitted between the UE and the network device, and the present application does not limit this. The UE and the network device can execute the methods provided by the embodiments of the present application.

[0097] To better introduce the embodiments of the present application, the methods provided by the embodiments of the present application will be introduced below with reference to the accompanying drawings. In each embodiment of the present application, the time unit includes, for example, a subframe, a time slot, a mini-slot, a group of OFDM symbols, or an OFDM symbol, etc., without specific limitation. Hereinafter, the OFDM symbol will be simply referred to as a symbol. In each embodiment of the present application, the modulation and coding scheme includes, for example, a modulation scheme and a coding rate. The modulation and coding scheme is, for example, MCS, or may also be other information or have other names, without specific limitation. Hereinafter, the modulation and coding scheme is MCS as an example for introduction. In the following drawings corresponding to the embodiments of the present application, unless otherwise specified, the steps represented by the dashed lines are all optional steps.

[0098] In various embodiments of the present application, the time units of the first type are, for example, time units of a non-SBFD type, and the time units of the second type are, for example, time units of an SBFD type; or, the time units of the first type are, for example, time units of an SBFD type, and the time units of the second type are, for example, time units of a non-SBFD type. Regarding how the two types of time units are implemented, there are the following several methods:

[0099] The first method: The protocol predefines that the time units of the first type are time units of an SBFD type or non-SBFD type;

[0100] The second method: The network device indicates through signaling that the time units of the first type are time units of an SBFD type or non-SBFD type;

[0101] The third method: Determine that the time units of the first type are time units of an SBFD type or non-SBFD type according to a predefined rule. For example, a predefined rule is that the time units of the first type are the time units corresponding to the nth transmission opportunity in the Kth repeated transmission of PXSCH, where K is a positive integer. Taking one transmission opportunity for one transmission as an example, then n is a positive integer less than or equal to K. PXSCH is PDSCH or PUSCH. For example, if n = 1, then the time units of the first type are the time units corresponding to the first transmission opportunity in the Kth repeated transmission of PXSCH.

[0102] Regarding the frequency-domain configuration of SBFD, the current standard discussion is that within one carrier range, at least DL subband and UL subband can be included. For whether there is a guard band between DL subband and UL subband and if the guard band exists, whether transmission can be performed on the guard band, all embodiments of the present application do not make any limitations. In addition, for whether DL subband and UL subband can overlap, all embodiments of the present application also do not make any limitations. Regarding the time-domain configuration of SBFD, according to whether an SBFD symbol and a non-SBFD symbol are simultaneously included within one time slot, there are the following two possible configuration methods. In all embodiments of the present application, it is not limited which of the following two configuration methods the embodiments of the present application are applied to, where the SBFD symbol can be considered as a symbol configured with SBFD, and the non-SBFD symbol can be considered as a symbol not configured with SBFD:

[0103] 1. The first configuration method: The configuration of SBFD is at the time-slot level, that is, all the symbols included in one time slot are either all configured as SBFD symbols or all configured as non-SBFD symbols;

[0104] 2. In the second configuration mode, the configuration of SBFD is at the symbol level, that is, among the symbols included in a time slot, a part can be configured as SBFD symbols, and the other part can be configured as non-SBFD symbols.

[0105] Each embodiment of this application can be executed by a first device and a second device. The first device is, for example, a UE, or a functional module capable of executing the method provided by the embodiments of this application. This functional module can be set in the UE, for example, a chip system in the UE; or this functional module can also be set independently of the UE. The second device is, for example, a network device, or a functional module capable of executing the method provided by the embodiments of this application. This functional module can be set in the network device, for example, a chip system in the network device; or this functional module can also be set independently of the network device. In the following introduction process, it is assumed that the first device is a UE and the second device is a network device as an example. The methods provided by each embodiment of this application can be applied to Figure 4 the network architecture shown. For example, the UE involved in each embodiment of this application can be Figure 4 the UE in Figure 4 ; the network device involved in each embodiment of this application can be

[0106] Embodiments of this application provide a communication method. Please refer to Figure 5 . Exemplarily, Figure 5 shows the flow of this method.

[0107] S501. The network device sends the first information. Correspondingly, the UE receives the first information.

[0108] The first information is, for example, DCI, or the first information is included in DCI; or, the first information can also be information at other protocol layers, such as a media access control (MAC) control element (CE) or a radio resource control (RRC) signaling, or the first information can also be included in the MAC CE or RRC signaling. For example, for dynamically scheduled PDSCH or PUSCH, the first information can be DCI. Or, for a configured grant or semi-persistent scheduling (SPS) PDSCH or PUSCH, the first information can be MAC CE or RRC signaling, etc.

[0109] The first information can schedule the first transport block (TB), where the first TB is to be repetitively transmitted. For example, the first TB can be transmitted over multiple transmission opportunities, and each transmission opportunity can transmit the first TB once, thereby achieving the repetitive transmission of the first TB. During the repetitive transmission process, the size of the first TB remains unchanged or the first TB remains unchanged, so that the first TB is transmitted multiple times. The first TB can be carried on the Physical Downlink Shared Channel (PDSCH) or on the Physical Uplink Shared Channel (PUSCH). For example, the first information can be used to schedule downlink transmission or uplink transmission.

[0110] Among them, the transmission opportunities of the first TB may be distributed over different types of time units. For example, some of the multiple transmission opportunities are located in the first type of time unit, while the remaining transmission opportunities are located in the second type of time unit. Embodiments of the present application can configure Modulation and Coding Schemes (MCS) for the first TB carried by these two types of time units respectively. For example, if the channel qualities of different types of time units are different, the MCSs configured for different types of time units can be different, so that the MCS applied to the TB carried by the corresponding time unit can adapt to the channel quality, thereby improving the transmission performance.

[0111] Since embodiments of the present application set MCSs for the two types of time units respectively, the first information can indicate the MCSs used by these two types of time units respectively. For example, the first information can indicate that the first TB is transmitted using the first MCS in the first type of time unit, or indicate that the transmission of the first TB in the first type of time unit uses the first MCS. In addition, the first information can also indicate that the first TB is transmitted using the second MCS in the second type of time unit, or indicate that the transmission of the first TB in the second type of time unit uses the second MCS. Through the indication of the first information, the receiving end of the first information (such as a User Equipment (UE)) can determine the MCS used by the first TB in different types of time units, so that the first TB can be correctly modulated and encoded or correctly demodulated and decoded. Optionally, the first MCS and the second MCS can be the same or different. For example, if the channel quality corresponding to the first type of time unit is the same as or differs little from the channel quality corresponding to the second type of time unit, the first MCS and the second MCS can be the same. In this way, both the transmission quality can be ensured and multiple MCSs do not need to be set, which can simplify the implementation of network devices. Another example is that if the channel quality corresponding to the first type of time unit is different from the channel quality corresponding to the second type of time unit, for example, differs greatly, the first MCS and the second MCS can be different, thereby ensuring the transmission quality on different time units. Embodiments of the present application provide a way to configure MCSs for two types of time units respectively, making it possible for the MCSs of different types of time units to be the same or different, which helps to improve the transmission quality.

[0112] To make the first MCS the same as the second MCS, the first modulation scheme and the second modulation scheme can be the same modulation scheme, and the first coding rate and the second coding rate can be the same. To make the first MCS different from the second MCS, the first modulation scheme is different from the second modulation and coding scheme, and / or the first coding rate is different from the second coding rate.

[0113] First, introduce how to make the first coding rate different from the second coding rate. In the embodiments of the present application, the first information can indicate the corresponding transmission resources for two types of time units respectively, thus equivalently realizing the separate indication of the coding rates corresponding to the two types of time units for this TB. If the coding rates corresponding to the two types of time units are indicated together, then the coding rates corresponding to the two types of time units should be the same, otherwise it is impossible to simultaneously indicate the coding rates corresponding to the two types of time units through one indication; while in the embodiments of the present application, the coding rates corresponding to the two types of time units can be separately indicated, thereby making the coding rates corresponding to the two types of time units have different possibilities.

[0114] For example, the first information can indicate the transmission resources of the first TB, and the transmission resources include a first resource and a second resource. The time units included in the first resource are time units of the first type, and the time units included in the second resource are time units of the second type. For example, the first resource is the resource corresponding to a transmission opportunity, and the second resource is the resource corresponding to another transmission opportunity. That is, the transmission resources of the first TB include the resources corresponding to two types of time units. To realize the separate indication of the coding rates corresponding to the two types of time units, it can be achieved by separately indicating the resources corresponding to the two types of time units. For example, the first information may include a second information and a third information, and further include a fourth information and / or a fifth information. The second information includes the time-domain resource information of the first resource (or the second information indicates the time-domain resources of the first resource), and the third information includes the frequency-domain resource information of the first resource (or the third information indicates the frequency-domain resources of the first resource); the fourth information includes the time-domain resource information of the second resource (or the fourth information indicates the time-domain resources of the second resource), and the fifth information includes the frequency-domain resource information of the second resource (or the fifth information indicates the frequency-domain resources of the second resource). It can be seen that the first information can indicate the transmission resources corresponding to the time units of the first type through the second information and the third information, and can indicate the transmission resources corresponding to the time units of the second type through the fourth information and / or the fifth information, thereby realizing the separate indication of the resources corresponding to the two types of time units, which is equivalent to implicitly indicating the coding rates corresponding to the two types of time units respectively.

[0115] The fourth information includes, for example, one or more domains, or one or more fields, or one or more IEs, etc., without limitation. The implementation of the fifth information, the second information, and the third information is similar. Taking the first information as DCI as an example, for example, the second information is the time domain resource allocation (TDRA) domain originally included in the DCI, the third information is the frequency domain resource allocation domain originally included in the DCI, the fourth information is the newly added TDRA domain in the DCI, and the fifth information is the newly added FDRA domain in the DCI.

[0116] For example, the first coding rate and the second coding rate can be different, or they can be the same. For example, in the embodiments of the present application, if it is desired to make the first MCS different from the second MCS, then it is possible to make only the first modulation scheme different from the second modulation scheme, while the first coding rate and the second coding rate can be the same; or it is possible to make only the first coding rate and the second coding rate different, while the first modulation scheme and the second modulation scheme can be the same; or it is possible to make the first modulation scheme different from the second modulation scheme, and the first coding rate and the second coding rate are also different.

[0117] As introduced above, the first information can indicate the transmission resources corresponding to different types of time units, thereby making the first coding rate and the second coding rate have different possibilities. If it is desired to make the first MCS different from the second MCS, it can also be achieved by separately indicating the modulation scheme, which is introduced as follows.

[0118] Taking the first information as DCI as an example, in the traditional DCI, there is only one field for indicating the MCS. For example, for the repeated transmission of PDSCH or PUSCH, the current solution is that the MCS remains unchanged during the repeated transmission, so one field is used to indicate the MCS. In the embodiments of the present application, different types of time units can be respectively configured with MCS, so the embodiments of the present application can introduce a new field in the first information to indicate another MCS. For example, the first information may include the sixth information and the seventh information. The sixth information can indicate the first MCS, and the seventh information can indicate the second MCS. The sixth information includes, for example, one or more domains, or one or more fields, or one or more information elements (IEs), etc., without limitation. The implementation of the seventh information is similar. Taking the first information as DCI as an example, for example, the sixth information is the MCS field originally included in the DCI, and the seventh information is the newly added MCS field in the DCI.

[0119] Among them, the first MCS may include a first modulation scheme and a first coding rate, and the second MCS may include a second modulation scheme and a second coding rate. Optionally, the seventh information may only indicate the second modulation scheme without necessarily indicating the second coding rate. This is because the size of the TB is determined according to the MCS and time-frequency resources of the TB on one type of time unit. When the size of the first TB remains unchanged, after the modulation scheme is determined, the coding rate is only related to the modulation scheme and the number of resource elements (REs) (assuming the number of layers of spatial division multiplexing remains unchanged). Therefore, for the transmission of the TB on another type of time unit, the coding rate may not be explicitly indicated, but the coding rate can be indicated by indicating the time-domain resource allocation and / or the frequency-domain resource allocation.

[0120] As introduced above, the sixth information may indicate the first modulation scheme and the first coding rate, and the seventh information may indicate the second modulation scheme. The sixth information indicates the first modulation scheme, specifically, it may indicate the first modulation scheme or the modulation order corresponding to the first modulation scheme. For example, it indicates that the first modulation scheme is quadrature phase shift keying (QPSK), or indicates that the modulation order corresponding to the first modulation scheme is 2. How the seventh information indicates the second modulation scheme is introduced as follows.

[0121] As an optional implementation manner for the seventh information to indicate the second modulation scheme, the seventh information indicates the second modulation scheme or the modulation order corresponding to the second modulation scheme; or it can be understood that the seventh information includes the information of the second modulation scheme or includes the information of the modulation order corresponding to the second modulation scheme. In this indication manner, the receiving end of the first information can directly determine the second modulation scheme or the modulation order according to the seventh information, and there is no need to rely on other information to determine the second modulation scheme or the modulation order. For example, some modulation schemes and modulation orders corresponding to NR PDSCH can be referred to Table 2.

[0122] Table 2

[0123]

[0124]

[0125] For example, the seventh piece of information may indicate that the second modulation scheme is 16QAM, or indicate that the modulation order corresponding to the second modulation scheme is 4. Alternatively, corresponding indexes or ranks may be set for each modulation scheme or modulation order respectively, and the seventh piece of information may indicate the index or rank of the second modulation scheme or the corresponding modulation order. For example, the index or rank of QPSK or modulation order 2 is set to 1, the index or rank of 16QAM or modulation order 4 is set to 2, the index or rank of 64QAM or modulation order 6 is set to 3, the index or rank of 256QAM or modulation order 8 is set to 4, the index or rank of 1024QAM or modulation order 10 is set to 5, etc. For example, if the seventh piece of information indicates 2, it means that the second modulation scheme is 16QAM or the modulation order is 4.

[0126] Table 2 takes PDSCH as an example. For PUSCH, the indication method of the seventh piece of information is similar and will not be elaborated here. Optionally, since the sets of modulation schemes supported by PDSCH and PUSCH may be different, one or more of the length, value, or meaning of the seventh piece of information in the first piece of information for scheduling PDSCH and the seventh piece of information in the first piece of information for scheduling PUSCH may be the same or different, and can be determined respectively according to the associated sets of modulation schemes.

[0127] As another optional implementation manner for the seventh piece of information to indicate the second modulation scheme, the seventh piece of information may indicate (or, include) the change amount of the second modulation order relative to the first modulation order. The first modulation order is the modulation order corresponding to the first modulation scheme, and the second modulation order is the modulation order corresponding to the second modulation scheme. If the second modulation order is the same as the first modulation order, the change amount is 0; if the second modulation order is different from the second modulation order, the change amount may be an upward or downward adjustment, or the change amount may be a positive or negative number.

[0128] Among them, the change amount can indicate the adjustment direction, but does not indicate the specific adjustment value. For example, when the value of the seventh piece of information is the first value, it can indicate that the second modulation order is down or up relative to the first modulation order, but does not indicate how much is specifically adjusted, or does not indicate what the specific adjustment is. In this case, the specific adjustment value can be a default value, or predefined by a protocol, or preconfigured by a network device, or preconfigured at the receiving end of the first piece of information. Then, the receiving end of the first piece of information can determine the second modulation order by combining the seventh piece of information and the adjustment value. The adjustment value is, for example, M levels, or M modulation orders, where M is a positive integer. As introduced above, levels can be set separately for different modulation schemes. If the adjustment value is M levels, the change amount indicates whether the level corresponding to the second modulation order is up or down relative to the level corresponding to the first modulation order. Taking Table 2 as an example, and taking the adjustment value as M modulation orders, for example, M = 2, the first modulation order is 4, and the seventh piece of information indicates that the second modulation order is down relative to the first modulation order. Then, the receiving end of the first piece of information can determine that the second modulation order is 2 by combining the adjustment amount and the first modulation order.

[0129] In this solution, the number of bits occupied by the seventh piece of information can be small. For example, only one bit is occupied. If the value of this bit is "0", it means that the second modulation order is down relative to the first modulation order. If the value of this bit is "1", it means that the second modulation order is up relative to the first modulation order. Please refer to Table 3 for an example of an implementation manner of the seventh piece of information.

[0130] Table 3

[0131] Value of the seventh information Indicate 1 Upward adjustment 0 Downward adjustment

[0132] Alternatively, generally speaking, the worse the channel quality, the lower the modulation order and coding rate should be; the better the channel quality, the higher the modulation order and coding rate should be. Taking the first type of time unit as a non - SBFD type of time unit and the second type of time unit as an SBFD type of time unit as an example, the channel quality of the second type of time unit is very likely to be worse than that of the first type of time unit. Then, the second modulation order can be lower than the first modulation order to adapt to the worse channel quality. Since the seventh piece of information indicates the second modulation scheme, the seventh piece of information can not indicate "up", but only indicate "down". For example, the seventh piece of information occupies one bit. If the value of this bit is "0", it means that the second modulation order is the same as the first modulation order. If the value of this bit is "1", it means that the second modulation order is down relative to the first modulation order. Please refer to Table 4 for an example of an implementation manner of the seventh piece of information.

[0133] Table 4

[0134] Value of the seventh information Indicate 1 Downward adjustment 0 Unchanged

[0135] Taking the case where the time unit of the first type is a time unit of the SBFD type and the time unit of the second type is a non - SBFD type time unit as an example, the channel quality of the time unit of the second type is likely to be better than that of the time unit of the first type. Then, the second modulation order can be higher than the first modulation order to adapt to the better channel quality. Since the seventh information indicates the second modulation scheme, the seventh information can not indicate "down - adjustment", but only indicate "up - adjustment". For example, the seventh information occupies one bit. If the value of this bit is "0", it means that the second modulation order remains unchanged relative to the first modulation order. If the value of this bit is "1", it means that the second modulation order is up - adjusted relative to the first modulation order. Please refer to Table 5 for an example of an implementation method of the seventh information.

[0136] Table 5

[0137] Value of the seventh information Indicate 1 Upward adjustment 0 Unchanged

[0138] Alternatively, the seventh information can indicate (or, include) the change amount of the second modulation order relative to the first modulation order, and this change amount can be a specific adjustment value. For example, when the value of the seventh information is the first value, it can indicate that the second modulation order is down - adjusted by M levels or up - adjusted by M levels relative to the first modulation order, or indicate that the second modulation order is down - adjusted by M levels or up - adjusted by M modulation orders relative to the first modulation order. In this case, there is no need to define the adjustment value through an additional method, which can simplify the implementation of the receiving end. Taking Table 2 as an example, and taking the seventh information indicating that the second modulation order is down - adjusted by M levels or up - adjusted by M modulation orders relative to the first modulation order as an example. For example, M is 2, the first modulation order is 4, and the seventh information indicates that the second modulation order is down - adjusted by 2 modulation orders relative to the first modulation order. Then, the receiving end of the first information can determine that the second modulation order is 2 by combining the seventh information and the first modulation order.

[0139] The seventh information can occupy one or more bits, and the M indicated by different values of the seventh information can be different. Taking the seventh information occupying 2 bits as an example, please refer to Table 6 for an example of an implementation method of the seventh information.

[0140] Table 6

[0141]

[0142] Taking Table 6 where the seventh information does not indicate up - adjustment as an example, in other implementation methods, the seventh information can also have corresponding values to indicate up - adjustment by M levels, and there is no restriction on this.

[0143] As another alternative implementation manner for the seventh information to indicate the second modulation scheme, the seventh information may indicate (or, include) the variation amount of the second modulation scheme relative to the first modulation scheme. Wherein, the seventh information indicates the variation amount of the second modulation scheme relative to the first modulation scheme. For example, it can be implemented by indicating the variation amount of the second modulation order relative to the first modulation order. For this, reference can be made to the foregoing text.

[0144] Alternatively, the seventh information indicates the variation amount of the second modulation scheme relative to the first modulation scheme, and it can also be implemented by indicating the variation amount of the level corresponding to the second modulation scheme relative to the level corresponding to the first modulation scheme. As introduced in the foregoing text, levels can be respectively set for different modulation schemes, and the seventh information may indicate the variation amount of the level corresponding to the second modulation scheme relative to the level corresponding to the first modulation scheme. For example, the index or level of QPSK or modulation order 2 is set to 1, the index or level of 16QAM or modulation order 4 is set to 2, the index or level of 64QAM or modulation order 6 is set to 3, the index or level of 256QAM or modulation order 8 is set to 4, the index or level of 1024QAM or modulation order 10 is set to 5, etc. By indicating the variation amount of the level, the indication of the second modulation scheme can also be achieved. If the level of the second modulation scheme is the same as the level of the first modulation scheme, then the variation amount is 0; if the level of the second modulation scheme is different from the level of the second modulation scheme, the variation amount can be an upward adjustment or a downward adjustment, or the variation amount can be a positive number or a negative number.

[0145] Wherein, the variation amount can indicate the adjustment direction, rather than indicating the specific adjustment value. For example, when the value of the seventh information is the first value, it can indicate that the level of the second modulation scheme is a downward adjustment or an upward adjustment relative to the level of the first modulation scheme, but does not indicate how much is specifically adjusted, or does not indicate specifically what it is adjusted to. In this case, the specific adjustment value can be a default value, or predefined by a protocol, or preconfigured by a network device, or preconfigured at the receiving end of the first information. Then, the receiving end of the first information combines the seventh information and the adjustment value to determine the second modulation order. The adjustment value is, for example, M levels, where M is a positive integer. For example, the adjustment amount is 1 level, the level of the first modulation scheme is 2, and the seventh information indicates that the level of the second modulation scheme is a downward adjustment relative to the level of the first modulation scheme. Then, the receiving end of the first information combines the adjustment amount and the first modulation order to determine that the level of the second modulation scheme is 1.

[0146] Alternatively, the seventh information may indicate (or include) the amount of change in the level of the second modulation scheme relative to the level of the first modulation scheme, and this amount of change may be a specific adjustment value. For example, if the value of the seventh information is a first value, it may indicate that the level of the second modulation scheme is lowered by M levels or raised by M levels relative to the level of the first modulation scheme. In this case, there is no need to define the adjustment value through an additional method, which can simplify the implementation at the receiving end. Taking Table 2 as an example, for instance, M is 1 level, the level of the first modulation scheme is 2, and the seventh information indicates that the level of the second modulation scheme is lowered by 1 level relative to the level of the first modulation scheme. Then, the receiving end of the first information can determine that the level of the second modulation scheme is 1 by combining the seventh information and the first modulation order.

[0147] In addition to the above method, the seventh information may also indicate the second modulation scheme in other ways, which is not limited herein.

[0148] Optionally, if the second modulation order determined according to the seventh information is less than the minimum modulation order supported by PXSCH, the receiving end of the first information may adopt the minimum modulation order supported by PXSCH instead of the second modulation order determined according to the seventh information; or, if the second modulation order determined according to the seventh information is greater than the minimum modulation order supported by PXSCH, the receiving end of the first information may adopt the maximum modulation order supported by PXSCH instead of the second modulation order determined according to the seventh information. Herein, PXSCH is, for example, PDSCH or PUSCH.

[0149] In the above introduction, the first information is used to schedule the first TB as an example. In addition, the first information can also schedule more TBs. For example, the first information can schedule the first TB and the second TB. The first TB and the second TB can be carried on the same physical channel (such as PDSCH or PUSCH). The time-domain resources and frequency-domain resources occupied by the first TB and the second TB can be the same, and the spatial-domain resources occupied can be different. Then, the time-domain resources used by the second TB for transmission on the first type of time unit can be indicated by the second information, and the frequency-domain resources used by the second TB for transmission on the first type of time unit can be indicated by the third information. Among them, the second information can indicate the time-domain resources used by the first TB for transmission on the first type of time unit, and the time-domain resources occupied by the first TB and the second TB can be the same. Therefore, it can be considered that the second information indicates both the time-domain resources used by the first TB for transmission on the first type of time unit and the time-domain resources used by the second TB for transmission on the first type of time unit; the third information can indicate the frequency-domain resources used by the first TB for transmission on the first type of time unit, and the frequency-domain resources occupied by the first TB and the second TB can be the same. Therefore, it can be considered that the third information indicates both the frequency-domain resources used by the first TB for transmission on the first type of time unit and the frequency-domain resources used by the second TB for transmission on the first type of time unit.

[0150] In addition, the time-domain resources used by the second TB for transmission on the second type of time unit can be indicated by the fourth information, and the frequency-domain resources used by the second TB for transmission on the second type of time unit can be indicated by the fifth information. Among them, the fourth information can indicate the time-domain resources used by the first TB for transmission on the second type of time unit, and the time-domain resources occupied by the first TB and the second TB can be the same. Therefore, it can be considered that the fourth information indicates both the time-domain resources used by the first TB for transmission on the second type of time unit and the time-domain resources used by the second TB for transmission on the second type of time unit; the fifth information can indicate the frequency-domain resources used by the first TB for transmission on the second type of time unit, and the frequency-domain resources occupied by the first TB and the second TB can be the same. Therefore, it can be considered that the fifth information indicates both the frequency-domain resources used by the first TB for transmission on the second type of time unit and the frequency-domain resources used by the second TB for transmission on the second type of time unit.

[0151] For the transmission of the second transport block (TB) on different types of time units, embodiments of the present application may also cause the first information to respectively indicate the corresponding modulation and coding scheme (MCS), so that the second TB can use the same or different MCSs for transmission on different types of time units, thereby facilitating the adjustment of the MCS of the second TB. For example, the first information may include the eighth information, and the MCS used by the second TB for transmission on the first type of time unit may be indicated by the eighth information. For example, the eighth information indicates that the second TB uses the third MCS for transmission on the first type of time unit. Herein, the third MCS may be the same as or different from the first MCS.

[0152] In addition, the modulation order (or modulation scheme) used by the second TB for transmission on the second type of time unit may be indicated by the seventh information included in the first information to save the transmission overhead of the first information; or the ninth information may be newly added to the first information, and the modulation order (or modulation scheme) used by the second TB for transmission on the second type of time unit may be indicated by the ninth information, or the MCS used by the second TB for transmission on the second type of time unit may be indicated, thereby separating the indication of the second TB from that of the first TB and ensuring the flexibility of the implementation of the network device and the user equipment (UE). Hereinafter, the MCS used by the second TB for transmission on the second type of time unit is referred to as the fourth MCS, and the modulation scheme used by the second TB for transmission on the second type of time unit is referred to as the fourth modulation scheme.

[0153] Among them, if the seventh information indicates both the second MCS (or indicates the second modulation scheme) and the fourth modulation scheme, it does not mean that the second modulation scheme and the fourth modulation scheme are the same, nor does it mean that the second MCS and the fourth MCS are the same. That is, when the seventh information indicates both the second MCS (or indicates the second modulation scheme) and the fourth modulation scheme, the second modulation scheme and the fourth modulation scheme may be the same or different, and the second MCS and the fourth MCS may be the same or different. For example, if the seventh information indicates the absolute value of the modulation order, the second MCS and the fourth MCS may be the same, or the second modulation scheme and the fourth modulation scheme may be the same. For another example, if the seventh information indicates the change amount of the modulation order, the fourth MCS may be jointly determined according to the seventh information and the eighth information, and the second MCS may be jointly determined according to the seventh information and the sixth information. Then, the determined second modulation scheme and fourth modulation scheme may be the same or different, and the second MCS and the fourth MCS may be the same or different.

[0154] Alternatively, for the MCS used by the first TB for transmission on time units of the second type and the MCS used by the second TB for transmission on time units of the second type, the first information may indicate them separately. For example, the first information may further include ninth information, and the ninth information may indicate the MCS used by the second TB for transmission on time units of the second type. For example, the modulation scheme is the fourth MCS. Herein, the fourth MCS may be the same as or different from the second MCS. By adding the ninth information, it provides the possibility of using different MCSs for the transmission of the first TB and the second TB on time units of the second type, improves the flexibility of implementation by the network device and the UE, and is conducive to improving the transmission performance. Regarding the specific indication manner of the ninth information, reference may be made to the introduction of the seventh information above, which will not be elaborated here.

[0155] Optionally, for the first TB, if only the coding rate is adjusted, for example, the first coding rate is made different from the second coding rate, and the modulation scheme is not adjusted, for example, the first modulation scheme is the same as the second modulation scheme, then the first information may not include the seventh information. Similarly, for the second TB, if only the coding rate of the second TB is adjusted, for example, the coding rate used by the second TB for transmission on time units of the first type is made different from the coding rate used by the second TB for transmission on time units of the second type, and the modulation scheme is not adjusted, for example, the modulation scheme used by the second TB for transmission on time units of the first type is the same as the modulation scheme used by the second TB for transmission on time units of the second type, then the first information may not include the ninth information.

[0156] Optionally, the method may further include S502, where the network device sends the first TB, and correspondingly, the UE receives the first TB; or, the UE sends the first TB, and correspondingly, the network device receives the first TB.

[0157] If the first TB scheduled by the first information is a downlink TB, the network device may send the first TB. Herein, the network device may send the first TB according to the indication of the first information. For example, the network device sends the first TB according to the time domain resource, frequency domain resource, MCS, etc. indicated by the first information, and the UE may also receive the first TB according to the indication of the first information. For this, reference may be made to the introduction of S501. Optionally, if the first information also schedules a second TB, the network device may also send the second TB. Herein, the network device may send the second TB according to the indication of the first information. For example, the network device sends the second TB according to the time domain resource, frequency domain resource, MCS, etc. indicated by the first information, and the UE may also receive the second TB according to the indication of the first information. For this, reference may be made to the introduction of S501.

[0158] Alternatively, if the first TB scheduled by the first information is an uplink TB, the UE may transmit the first TB. The UE may transmit the first TB according to the indication of the first information, for example, transmit the first TB according to the time domain resource, frequency domain resource, MCS, etc. indicated by the first information. The network device may also receive the second TB according to the first information. For this, reference may be made to the introduction of S501. Optionally, if the first information also schedules a second TB, the UE may also transmit the second TB. The UE may transmit the second TB according to the indication of the first information, for example, transmit the second TB according to the time domain resource, frequency domain resource, MCS, etc. indicated by the first information. The network device may also receive the second TB according to the first information. For this, reference may be made to the introduction of S501.

[0159] Optionally, the UE may determine that the time unit of the first type is a non-SBFD type of time unit and determine that the time unit of the second type is an SBFD type of time unit according to the signaling indication from the network device, or according to a predefined rule, or according to the information pre-configured in the UE, etc., or determine that the time unit of the first type is a sub-band duplex SBFD type of time unit and determine that the time unit of the second type is a non-SBFD type of time unit.

[0160] As a possible implementation manner, the network device may indicate by information that the time unit of the first type is a non-SBFD type of time unit. Correspondingly, the time unit of the second type is an SBFD type of time unit; or, the network device may indicate by information that the time unit of the first type is an SBFD type of time unit. Correspondingly, the time unit of the second type is a non-SBFD type of time unit. For example, the network device sends the tenth information to the UE. The tenth information may indicate what types the two types of time units are respectively. The UE may determine the two types of time units according to the tenth information. The tenth information may be included in the first information, or the tenth information may also be included in other information sent by the network device, or the tenth information may also be included in the message newly defined in the embodiments of the present application, and this message is used to indicate the type of the time unit.

[0161] As a possible implementation manner, the first type is the type of the time unit where the first valid transmission opportunity in the repeated transmission of the first TB or the second TB is located. For example, if the first valid transmission opportunity in the repeated transmission of the first TB or the second TB is located in a time unit of the SBFD type, the time unit of the first type is a time unit of the SBFD type. Correspondingly, the time unit of the second type is a non-SBFD type of time unit; or, if the first valid transmission opportunity in the repeated transmission of the first TB or the second TB is located in a time unit of the non-SBFD type, the time unit of the first type is a time unit of the non-SBFD type. Correspondingly, the time unit of the second type is a time unit of the SBFD type.

[0162] The first information in the embodiments of the present application can indicate the first modulation and coding scheme corresponding to the time units of the first type, or can also indicate the second modulation and coding scheme corresponding to the time units of the second type. Equivalently, the embodiments of the present application can respectively indicate the modulation and coding schemes for different types of time units, thereby providing the possibility of implementing different modulation and coding schemes for different types of time units. For example, if the channel qualities of different types of time units are different, the modulation and coding schemes indicated for different types of time units can be different, so that the modulation and coding schemes applied to the transport blocks carried by the corresponding time units can be adapted to the channel quality to improve the transmission performance.
