[0002] The present application relates to the field of communication technology, and in particular to a communication method and apparatus. BACKGROUND

[0003] With the increase of service demand, the number of users in the communication system is increasing. At present, the signal interference suppression scheme (for example, the data transmission between users is performed by using the space division multiplexing mode) adopted by the communication system cannot effectively suppress the signal interference between users. Therefore, how to further suppress the signal interference is a problem to be solved. SUMMARY

[0004] The present application provides a communication method and related apparatus, wherein a first communication apparatus performs time domain precoding on data on each time domain unit in the first time domain unit to the Nth time domain unit by using the first factor to the Nth factor, which is beneficial to further suppress the signal interference between users. For example, two communication apparatuses in a communication system can perform the above technical solution respectively, so as to avoid or reduce the signal interference between the two communication apparatuses when the two communication apparatuses perform data transmission in the first time domain unit to the Nth time domain unit.

[0005] The first aspect of the present application provides a communication method, which can be applied to a first communication device. The first communication device can be a terminal device, or a component (for example, a processor, a chip, or a chip system, etc.) in the terminal device, or a logic module or software capable of realizing all or part of the functions of the terminal device. The method comprises: receiving, by the first communication device, first information, the first information indicating N time domain units for repeatedly sending data, N being an integer greater than 1. The first communication device determines, according to N and a first resource, a first time domain unit to an Nth time domain unit, the first resource comprising the first time domain unit to the Nth time domain unit, the first time domain unit to the Nth time domain unit comprising an ith time domain unit, 1≤i≤N, i being an integer. The first communication device receives second information, the second information indicating a first factor to an Nth factor, the first factor to the Nth factor comprising the ith factor, the ith factor corresponding to the to-be-sent data of the ith time domain unit. The first communication device performs time domain precoding on first data according to the first factor to the Nth factor, to obtain first time domain precoding data to Nth time domain precoding data, the first data being the to-be-sent data of each time domain unit in the first time domain unit to the Nth time domain unit. The first communication device sends the first time domain precoding data to the Nth time domain precoding data on the first time domain unit to the Nth time domain unit, respectively.

[0006] As can be seen from the above, the present application proposes a time domain precoding manner. The first communication device can receive first information, and determine, according to N and a first resource indicated by the first information, a first time domain unit to an Nth time domain unit. Then, the first communication device receives second information, the second information indicating a first factor to an Nth factor, the first factor to the Nth factor comprising an ith factor, the ith factor corresponding to the to-be-sent data of the ith time domain unit. In this way, the first communication device performs time domain precoding on the data in each time domain unit in the first time domain unit to the Nth time domain unit through the first factor to the Nth factor, which is conducive to further suppressing the signal interference between users. For example, two communication devices in a communication system can each use the above technical solution, thereby avoiding or reducing the signal interference between the two communication devices when they perform data transmission in the first time domain unit to the Nth time domain unit. Further, the first communication device performs time domain precoding on the to-be-sent data of each time domain unit before sending the time domain precoding data, which is conducive to resisting the time variation of the channel and improving the performance of data transmission.

In the implementation manner, the second communication device further indicates the granularity of the time domain unit to the first communication device, so that the granularity of the time domain unit is flexibly configured, and the first communication device is facilitated to determine the first time domain unit to the Nth time domain unit, so as to realize that the first communication device repeatedly sends data and improves data transmission performance.

In the implementation manner, the second communication device further indicates the first communication device that two time domain units that are adjacent in sequence in the N time domain units are discontinuous in time domain, thereby facilitating the first communication device to determine the first time domain unit to the Nth time domain unit.

[0012] In a possible implementation manner of the first aspect, the fifth information is carried in RRC configuration information, MAC CE signaling or DCI signaling. In the implementation manner, some possible carrying carriers of the fifth information are shown, thereby realizing the second communication device indicating the first communication device that two time domain units that are adjacent in sequence in the N time domain units are discontinuous in time domain.

[0013] In a possible implementation manner of the first aspect, the time domain unit is a symbol or a symbol group, and two time domain units that are adjacent in sequence in the N time domain units are located in a same time slot or different time slots. In this way, implementation of the scheme is enriched. The N time domain units can be in a same time slot or cross time slots, thereby making application scenarios of the scheme more abundant. For example, the scheme is applicable to scenarios in which uplink time slots in a communication system are continuous or discontinuous.

In the implementation manner, the first communication device receives the sixth information, and based on the sixth information, triggers the first communication device to perform time domain precoding on the first data according to the first factor to the Nth factor.

[0116] Currently, in a communication system, a communication device can perform uplink and downlink transmission in a duplex manner. In a possible implementation, the communication device determines uplink time slots and downlink time slots according to an uplink and downlink time slot ratio, and performs uplink transmission in the uplink time slots and performs downlink transmission in the downlink time slots. As shown in FIG. 3, the uplink and downlink time slot ratio is 4:1, i.e., the number of downlink time slots: the number of uplink time slots is 4:1. In another possible implementation, the communication device determines uplink resources and downlink resources according to a sub-band duplex manner, and performs uplink transmission in the uplink resources and performs downlink transmission in the downlink resources. As shown in FIG. 4, the uplink and downlink time slot ratio of a first sub-band in a first bandwidth can be changed, i.e., the uplink and downlink time slot ratio of the first sub-band is different from the uplink and downlink time slot ratio of other frequency bands in the first bandwidth. For example, all time slots in the first sub-band can be uplink time slots.

[0117] The communication system to which the technical solutions provided in the present application are applied includes a first communication device and a second communication device. Optionally, the first communication device is a terminal device, or a chip, a chip system, or a processor in the terminal device, or a logic module or software for implementing part or all of the terminal device.

[0118] Optionally, the communication system further comprises a third communication device, which is a network device, or a chip, a chip system, or a processor in the network device; or a logic module or software, etc. for implementing part or all of the network device.

[0119] The terminal device and the network device are described below.

[0120] The terminal device is also referred to as a UE, a mobile station (MS), a mobile terminal (MT), a fixed wireless access (FWA), a customer premise equipment (CPE), etc. The terminal device is a device including a wireless communication function (providing voice / data connectivity to a user). For example, a handheld device with wireless connectivity, a vehicle-mounted device, a machine type communication (MTC) terminal, etc. At present, the terminal device can include a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving (e.g., a drone, a vehicle), a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home, etc. For example, the wireless terminal in self driving can be a drone, a helicopter, or an airplane, etc. For example, the wireless terminal in vehicle networking can be a vehicle-mounted device, a whole-vehicle device, a vehicle-mounted module, a vehicle, or a ship, etc. The wireless terminal in industrial control can be a camera, a robot, or a mechanical arm, etc. The wireless terminal in a smart home can be a television, an air conditioner, a sweeping machine, a sound box, or a set-top box, etc. The terminal device can also be a device or a module with corresponding communication functions for accessing the above-illustrated communication system. The terminal device is usually provided with a communication module, a circuit or a chip for executing corresponding communication functions, and is further configured with program instructions for executing corresponding communication functions.

[0121] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus integrated with a circuit, or a chip, a chip system, a module or a control unit in the above-mentioned device or apparatus, and the specific application is not limited. It should be noted that in this application, when referring to the terminal device, it can refer to the terminal device itself, or the chip, functional module or integrated circuit in the terminal device that completes the method provided in the application, and the specific application is not limited.

[0122] The network device can be a device in a wireless network. For example, the network device can be an access network node that accesses a terminal device to a wireless network, which can also be referred to as a base station. Currently, some examples of the network device are: a base station (gNodeB, gNB) in a 5G communication system, a transmission reception point (TRP), an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a home base station (for example, a home evolved Node B, or a home Node B, HNB), a baseband unit (BBU), or a wireless fidelity (Wi-Fi) access point AP, and the like. In addition, in a network structure, the network device can include a centralized unit (CU) node, a distributed unit (DU) node, a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), or a RAN device including the CU node and the DU node. The CU and the DU can be separately arranged, or can also be included in the same network element, for example, in a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, for example, in a remote radio unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH). In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings.

Among them, any one of the CU (or CU-CP, CU-UP), DU and RU can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0123] The network device can be another device providing wireless communication function for the terminal device. Embodiments of the present application do not limit the specific technology and specific device form of the network device. For the convenience of description, embodiments of the present application do not limit.

[0124] It should be noted that the network device can be a device or apparatus with a chip, or a device or apparatus integrated with a circuit, or a chip, chip system, module or control unit in the above-mentioned device or apparatus, and the specific application is not limited. It should be noted that in the present application, when referring to the network device, it can refer to the network device itself, or the chip, functional module or integrated circuit in the network device that completes the method provided by the present application, and the specific application is not limited.

[0125] With the increase of service demand, more and more users are in the communication system. At present, the communication system adopts the scheme of suppressing signal interference between users (for example, using spatial division multiplexing to transmit data between users) which cannot effectively suppress the signal interference between users. As shown in FIG. 5, the terminal device 501 and the terminal device 502 use spatial division multiplexing to transmit data. The terminal device 501 and the terminal device 502 are close to each other, and the spatial division multiplexing effect is not ideal, in other words, the signal interference between the terminal device 501 and the terminal device 502 is still large. Therefore, how to further suppress the signal interference between users is a problem worth considering.

[0126] The present application provides corresponding technical solutions. The first communication device performs time domain precoding on the data in each time domain unit in the first time domain unit to the Nth time domain unit through the first factor to the Nth factor, which is conducive to further suppressing the signal interference between users. For example, two communication devices in a communication system can use the above technical solutions to realize that the two communication devices do not interfere with each other when transmitting data on the first time domain unit to the Nth time domain unit respectively.

[0127] The technical solutions of the present application will be described below in conjunction with specific embodiments.

[0128] FIG. 6 is a schematic diagram of one embodiment of the communication method of the present application. Please refer to FIG. 6, the method comprises:

[0129] 601, the second communication device sends the first information to the first communication device. Correspondingly, the first communication device receives the first information from the second communication device.

[0130] The first information indicates N time domain units used for repeatedly sending data. N is an integer greater than 1. That is, the N time domain units are used for repeatedly sending the same data. In other words, the first information indicates the number N of time domain units used for repeatedly sending data. For example, as shown in FIG. 7, the time domain unit is a time slot, and the number of time slots used for repeatedly sending the same data is 3. For another example, as shown in FIG. 8, the time domain unit is a symbol, and the number of symbols used for repeatedly sending the same data is 7. For another example, as shown in FIG. 9, the time domain unit is a symbol group, and the number of symbol groups used for repeatedly sending the same data is 3. For example, the first information includes a first field, and a value of the first field is used to indicate the number N of time domain units used for repeatedly sending the same data. For example, the first field includes two bits, and when the value of the two bits is “11”, it indicates that the number of time domain units used for repeatedly sending the same data is 3. For another example, the first field includes three bits, and when the value of the three bits is “111”, it indicates that the number of time domain units used for repeatedly sending the same data is 7. The above shows some examples of the first field, and does not limit the solutions of the present application.

[0131] Optionally, the time domain unit is a time slot, a time slot group, a sub-time slot, a sub-time slot group, a symbol, or a symbol group. The time slot group includes one or more time slots. The sub-time slot group includes one or more sub-time slots. The symbol group includes one or more symbols. It can be known that the granularity of the time domain unit can be the time slot level, the time slot group level, the sub-time slot level, the sub-time slot group level, the time domain symbol level, or the time domain symbol group level.

[0132] Optionally, the granularity of the time domain unit is predefined, or is specified by a communication protocol, or is indicated by the second communication device to the first communication device.

[0133] The following introduces two implementation manners of the second communication device indicating the granularity of the time domain unit to the first communication device. The present application is still applicable to other implementation manners, and the present application is not limited in particular.

[0134] Implementation manner 1: The first information further indicates that the time domain unit is a time slot, a time slot group, a sub-time slot, a sub-time slot group, a symbol, or a symbol group. For example, the first information includes a second field, and a value of the second field is used to indicate that the time domain unit is a time slot, a time slot group, a sub-time slot, a sub-time slot group, a symbol, or a symbol group. For example, the second field includes one bit, and when the value of the one bit is “0”, it indicates that the time domain unit is a time slot, and when the value of the one bit is “1”, it indicates that the time domain unit is a symbol. Or, when the value of the one bit is “1”, it indicates that the time domain unit is a time slot, and when the value of the one bit is “0”, it indicates that the time domain unit is a symbol. The above shows some examples of the second field, and does not limit the solutions of the present application.

[0135] In implementation 2, the embodiment shown in Fig. 6 further includes step 601a. Step 601a can be performed before step 602.

[0136] 601a. The second communication device sends third information to the first communication device. Correspondingly, the first communication device receives the third information from the second communication device.

[0137] The third information further indicates that the time domain unit is a time slot, a time slot group, a sub-time slot, a sub-time slot group, a symbol, or a symbol group. The granularity of the time domain unit indicated by the third information is similar to the granularity of the time domain unit indicated by the first information. For details, refer to the description of the manner of indicating the granularity of the time domain unit by the first information, which is not repeated here.

[0138] It should be noted that there is no fixed execution order between step 601 and step 601a. For example, step 601 can be performed first, and then step 601a can be performed. Alternatively, step 601a can be performed first, and then step 601 can be performed. Alternatively, steps 601 and 601a can be performed simultaneously according to the situation, and the specific implementation is not limited in the present application.

[0139] Optionally, the N time domain units are continuous in time domain. Optionally, in this implementation, the first communication device performs uplink and downlink transmission in a sub-band duplex manner. For details, refer to the description of Fig. 4. For example, as shown in Fig. 7, the N time domain units include time slot S1, time slot S2, and time slot S3. Time slot S1, time slot S2, and time slot S3 are three time slots continuous in time domain. For another example, as shown in Fig. 8, the N time domain units include symbols 0 to 6. Symbols 0 to 6 are seven symbols continuous in time domain. For another example, as shown in Fig. 9, the N time domain units include symbol 1, symbol group 2, and symbol group 3. Symbol group 1, symbol group 2, and symbol group 3 are three symbol groups continuous in time domain.

[0140] Optionally, the N time domain units being continuous in time domain can be predefined, or specified by a communication protocol, or indicated by the second communication device to the first communication device. Some possible implementation manners of the second communication device indicating the N time domain units being continuous in time domain to the first communication device are introduced below. The present application is still applicable to other implementation manners, and the specific implementation is not limited in the present application.

[0141] In an implementation, the first information further indicates that the N time domain units are continuous in time domain. For example, the first information includes a fourth field, and a value of the fourth field is used to indicate that the N time domain units are continuous in time domain. For example, the fourth field includes one bit, and a value of the one bit is "0" to indicate that the N time domain units are continuous in time domain. Or, the value of the one bit is "1" to indicate that the N time domain units are continuous in time domain. It should be noted that the above describes some possible implementations of the fourth field, and the present application does not limit the implementation of the fourth field in actual application.

[0142] In an implementation, the third information further indicates that the N time domain units are continuous in time domain. The third information indicates that the N time domain units are continuous in time domain in a manner similar to the manner in which the first information indicates that the N time domain units are continuous in time domain, which will not be described herein.

[0143] In an implementation, the embodiment shown in FIG. 6 further includes step 601b.

[0144] 601b. The second communication device sends fourth information to the first communication device. Correspondingly, the first communication device receives the fourth information from the second communication device.

[0145] The fourth information indicates that the N time domain units are continuous in time domain. The fourth information indicates that the N time domain units are continuous in time domain in a manner similar to the manner in which the first information indicates that the N time domain units are continuous in time domain, which will not be described herein.

[0146] It should be noted that there is no fixed execution order between step 601b and step 601. For example, step 601b can be executed first, and then step 601 can be executed. Or, step 601 can be executed first, and then step 601b can be executed. Or, steps 601 and 601b can be executed at the same time according to the situation, which will not be limited by the present application.

[0147] It should be noted that if the embodiment shown in FIG. 6 further includes step 601a, there is no fixed execution order between step 601, step 601a and step 601b, which will not be limited by the present application. For example, step 601 can be executed first, then step 601a can be executed, and finally step 601b can be executed. Or, step 601a can be executed first, then step 601b can be executed, and finally step 601 can be executed, which will not be limited by the present application.

[0148] Optionally, the two time domain units that are adjacent in sequence in the N time domain units are discontinuous in time domain. Optionally, in this implementation, the first communication device performs uplink and downlink transmission according to an uplink and downlink time slot ratio. As shown in FIG. 10, the uplink and downlink time slot ratio is 1:1, time slot S1 is an uplink time slot, time slot S2 is a downlink time slot, time slot S3 is an uplink time slot, time slot S4 is a downlink time slot, time slot S5 is an uplink time slot, and time slot S6 is a downlink time slot. As shown in FIG. 10, the N time domain units include three time slots, namely time slot S1, time slot S3, and time slot S5. The sequence of time slot S1 in the three time slots is 1, the sequence of time slot S3 in the three time slots is 2, and the sequence of time slot S5 in the three time slots is 3. As shown in FIG. 10, time slot S1 and time slot S3 are separated by one time slot (i.e., time slot S2, which is a downlink time slot), that is, time slot S1 and time slot S3 are discontinuous in time domain. Time slot S3 and time slot S5 are separated by one time slot (i.e., time slot S4), that is, time slot S3 and time slot S5 are discontinuous in time domain. It should be noted that the uplink and downlink time slot ratio shown in FIG. 10 is only an example, and in actual application, the uplink and downlink time slot ratio can be other ratios, for example, the uplink and downlink time slot ratio is 4:1, or 2:1, etc., which is not limited in the present application. For another example, as shown in FIG. 11, the N time domain units include two symbol groups, namely symbol group 1 and symbol group 5. The sequence of symbol group 1 in the two symbol groups is 1, and the sequence of symbol group 5 in the two symbol groups is 2. Symbol group 1 and symbol group 5 are discontinuous in time domain.

[0149] Optionally, the discontinuity of the two time domain units that are adjacent in sequence in the N time domain units in time domain is predefined, or is specified by a communication protocol, or is indicated by the second communication device to the first communication device.

[0150] The following describes some possible implementation modes of the indication of the discontinuity of the two time domain units that are adjacent in sequence in the N time domain units in time domain by the second communication device to the first communication device. The present application is still applicable to other implementation modes, which is not limited in the present application.

[0151] Implementation mode 1: The first information further indicates the discontinuity of the two time domain units that are adjacent in sequence in the N time domain units in time domain. For example, the first information includes a fifth field, and a value of the fifth field is used to indicate the discontinuity of the two time domain units that are adjacent in sequence in the N time domain units in time domain. For example, the fifth field includes one bit, and a value of the one bit is 0, indicating the discontinuity of the two time domain units that are adjacent in sequence in the N time domain units in time domain. Or, the value of the one bit is 1, indicating the discontinuity of the two time domain units that are adjacent in sequence in the N time domain units in time domain.

[0152] In an implementation, the third information further indicates that two time domain units that are adjacent in sequence in the N time domain units are discontinuous in time domain. The third information indicates that two time domain units that are adjacent in sequence in the N time domain units are discontinuous in time domain in a manner similar to that in which the first information indicates that two time domain units that are adjacent in sequence in the N time domain units are discontinuous in time domain. For details, refer to the foregoing description.

[0153] In an implementation, the method further includes step 601c.

[0154] 601c. The second communication device sends fifth information to the first communication device. Correspondingly, the first communication device receives the fifth information from the second communication device.

[0155] The fifth information indicates that two time domain units that are adjacent in sequence in the N time domain units are discontinuous in time domain. The fifth information indicates that two time domain units that are adjacent in sequence in the N time domain units are discontinuous in time domain in a manner similar to that in which the first information indicates that two time domain units that are adjacent in sequence in the N time domain units are discontinuous in time domain. For details, refer to the foregoing description.

[0156] It should be noted that there is no fixed execution order between step 601 and step 601c. For example, step 601 is executed first, and then step 601c is executed. Alternatively, step 601c is executed first, and then step 601 is executed. Alternatively, step 601 and step 601c are executed simultaneously, depending on the situation. The specific implementation is not limited in the present application.

[0157] It should be noted that if the embodiment shown in FIG. 6 further includes step 601a, there is no fixed execution order between step 601, step 601a, and step 601c. For example, step 601 can be executed first, step 601a can be executed second, and step 601c can be executed last. Alternatively, step 601c can be executed first, step 601a can be executed second, and step 601 can be executed last. The specific implementation is not limited in the present application.

[0158] Alternatively, the time domain unit is a symbol or a symbol group, and two time domain units that are adjacent in sequence in the N time domain units are located in a same time slot or different time slots. For example, as shown in FIG. 8, the N time domain units include seven symbols, namely, symbol 0 to symbol 6. The sequence of symbol 0 in the seven symbols is 1, the sequence of symbol 1 in the seven symbols is 2, and so on, and the sequence of symbol 6 in the seven symbols is 7. Symbol 0 to symbol 6 are all located in time slot 0. For another example, as shown in FIG. 11, the N time domain units include symbol group 1 and symbol group 5. Symbol group 1 is located in time slot 0, and symbol group 5 is located in time slot 1.

[0159] Optionally, the first information comprises a first index. The first index indicates a number N of time domain units for repeatedly sending the data. Optionally, the first index further indicates at least one of: a granularity of the time domain units, or the N time domain units are consecutive in time domain. Or, optionally, the first index further indicates at least one of: the granularity of the time domain units, or two time domain units adjacent in order among the N time domain units are non-consecutive in time domain. Thus, the indication overhead is reduced.

[0160] Optionally, the first information is carried in RRC configuration information, MAC CE signaling, or DCI signaling.

[0168] 602. The first communication device determines the first time domain unit to the Nth time domain unit according to the N and the first resource.

[0169] The first resource is a first uplink resource or a first sidelink resource. Optionally, the first resource is preconfigured or pre-determined. For example, the first resource is an uplink resource scheduled by the second communication device for the first communication device.

[0170] In a possible implementation, the plurality of time slots occupied by the first uplink resource are discontinuous. For example, as shown in FIG. 3, the first uplink resource can include uplink time slots as shown in FIG. 3.

[0171] In another possible implementation, the plurality of time slots occupied by the first uplink resource are continuous. For example, as shown in FIG. 4, the first uplink resource can include uplink time slots as shown in FIG. 4.

[0172] The first time domain unit to the Nth time domain unit includes the first time domain unit, the second time domain unit, the third time domain unit, and the Nth time domain unit. Specifically, the first communication device determines the first time domain unit to the Nth time domain unit from the first resource according to the N. For example, the first time domain unit is the first time domain unit in the first resource or the Pth time domain unit in the first resource. P is an integer greater than 1. Each time domain unit in the first time domain unit to the Nth time domain unit is used for repeatedly sending the first data.

Then, the first communication device performs the step 602 again.

[0176] 603、The second communication device sends the second information to the first communication device. Correspondingly, the first communication device receives the second information from the second communication device.

[0177] The second information indicates the first factor to the Nth factor. N is an integer greater than 1. The first factor to the Nth factor includes: the first factor, the second factor, the third factor, …, and the Nth factor. The first factor to the Nth factor includes the ith factor, and the ith factor corresponds to the to-be-sent data of the ith time domain unit. In other words, the first factor corresponds to the to-be-sent data of the first time domain unit, and the first factor is used for time domain precoding on the to-be-sent data of the first time domain unit. The second factor corresponds to the to-be-sent data of the second time domain unit, and the second factor is used for time domain precoding on the to-be-sent data of the second time domain unit. Similarly, the Nth factor corresponds to the to-be-sent data of the Nth time domain unit, and the Nth factor is used for time domain precoding on the to-be-sent data of the Nth time domain unit. It should be noted that, optionally, each factor in the first factor to the Nth factor can be a complex scalar, for example, a+bj.

[0178] For example, as shown in FIG. 7, the first time domain unit to the Nth time domain unit include a time slot S1, a time slot S2, and a time slot S3. The first factor to the Nth factor include and corresponding to the time slot S1, for the time slot S2, corresponding to the time slot S3.

[0180] For another example, as shown in FIG. 9, the first time domain unit to the Nth time domain unit include a symbol group 1, a symbol group 2, and a symbol group 3. The first factor to the Nth factor include and corresponding to the symbol group 1, corresponding to the symbol group 2, corresponding to the symbol group 3.

[0181] For another example, as shown in FIG. 10, the first time domain unit to the Nth time domain unit include a time slot S1, a time slot S3, and a time slot S5. The first factor to the Nth factor include and corresponding to the time slot S1, corresponding to the time slot S3, corresponding to the time slot S5.

[0183] A possible implementation of the first communication device determining the first factor to the Nth factor will be described below in combination with FIG. 7. For example, the first communication device is a first terminal device, and the second communication device is a network device. The network device determines a first uplink channel matrix H1 between the first terminal device and the network device. The first uplink channel matrix H1 represents an uplink channel between the first terminal device and the network device at present. Then, the network device estimates a second uplink channel matrix H2 according to the first uplink channel matrix. The second uplink channel matrix H2 is an estimated uplink channel matrix for representing an uplink channel between the first terminal device and the network device in a future time period. The future time period includes the first time domain unit to the Nth time domain unit. Then, the network device performs spatial domain averaging on the second uplink channel matrix H2, and obtains k is an integer greater than or equal to 1 and less than or equal to N. The network device performs singular value decomposition on a covariance matrix of and obtains a v vector of the first terminal device (i.e., a right singular matrix). The v vector of other terminal devices is obtained in a similar manner on the first time domain unit to the Nth time domain unit. The network device performs zero-breaking processing on the v vectors of different first terminal devices, and obtains a precoding vector of each terminal device. For example, as shown in FIG. 7, the precoding vector of the first terminal device is P1, is the first factor, is the second factor, is the third factor. The precoding vector of the second terminal device is P2, It should be noted that the precoding vector P1 is orthogonal to the precoding vector P2, so as to avoid signal interference between the first terminal device and the second terminal device when the first terminal device and the second terminal device respectively transmit data on the first time domain unit to the Nth time domain unit. Therefore, the inter-user signal interference is further suppressed.

[0184] It should be noted that the above step 603 is described by taking an example that the second information is from the second communication device. In actual application, the above step 603 can also be described as: the third communication device sends the second information to the first communication device. Correspondingly, the first communication device receives the second information from the third communication device. For example, the second communication device and the third communication device are two different network devices.

[0185] Optionally, there is no fixed execution order between the step 601 and the step 603, and the application does not limit the execution order. For example, the step 601 can be executed first, and then the step 603 is executed; or the step 603 can be executed first, and then the step 601 is executed; or the step 601 and the step 603 can be executed simultaneously according to the situation, and the application does not limit the execution order.

[0186] In a possible implementation, the first information further indicates that the first data is time domain precoded according to the first factor to the Nth factor. Alternatively, the first information further indicates that the data is time domain precoded in a time domain precoding manner. The time domain precoding manner can be understood as the data processing manner shown in the step 604. After the first communication device receives the sixth information, the first communication device time domain precodes the data in the time domain precoding manner on the first resource. Optionally, the sixth information includes a sixth field, and a value of the sixth field indicates that the first data is time domain precoded according to the first factor to the Nth factor, or indicates that the data is time domain precoded in the time domain precoding manner. For example, the sixth field is a transmission time domain precoding enable (TSP_enable) field, and when a value of the transmission time domain precoding enable field is “1”, it indicates that the first data is time domain precoded according to the first factor to the Nth factor, or indicates that the data is time domain precoded in the time domain precoding manner. It should be noted that the above-mentioned implementation of the sixth field is only an example, and the implementation of the sixth field is not limited.

[0187] In another possible implementation, the second information further indicates that the first data is time domain precoded according to the first factor to the Nth factor. Alternatively, the second information further indicates that the data is time domain precoded in a time domain precoding manner. In this implementation, the second information indicates the precoding manner similar to the precoding manner indicated by the first information, which is not described herein.

Alternatively, the fifth information further indicates that the data is time domain precoded in a time domain precoding manner. In this implementation, the fifth information indicates the precoding manner similar to the precoding manner indicated by the first information, which will not be repeated here.

[0191] In yet another possible implementation, the embodiment shown in FIG. 6 further includes step 603a.

In another possible implementation, the sixth information indicates that the data is time domain precoded in a time domain precoding manner.

[0194] In response to the first information, the second information, the third information, the fourth information, the fifth information, or the sixth information, the first communication device performs step 604.

[0195] Alternatively, the sixth information is carried in RRC signaling, MAC CE signaling, or DCI signaling. The sixth information indicates the precoding manner similar to the precoding manner indicated by the first information, which will not be repeated here.

[0204] 605、The first communication device transmits the first time domain precoding data to the Nth time domain precoding data on the first time domain unit to the Nth time domain unit respectively.

[0205] In a possible implementation, the first communication device transmits the first time domain precoding data on the first time domain unit, the second time domain precoding data on the second time domain unit, and so on, and the Nth time domain precoding data on the Nth time domain unit.

Thus, the inter-user signal interference is further suppressed.

[0213] ​In one possible implementation, starting from the (N+1)th time-domain unit, the first communication device can continue to precode the data using time-domain precoding before retransmission. The specific process is similar to steps 601 to 605 described above, and will not be repeated here. For example, as shown in Figure 7, the (N+1)th to the 2Nth time-domain units include time slots S4, S5, and S6.

[0215] 606. The first communication device determines the (N+1)th time domain unit based on N and the first resource.

[0216] The first resource includes the (N+1)th time-domain element. The (N+1)th time-domain element is the time-domain element following the Nth time-domain element. Optionally, the (N+1)th time-domain element is the (N+1)th time-domain element.

[0217] 607. The first communication device transmits the second data in the N+1 time domain unit.

[0218] Specifically, the first communication device does not perform time-domain precoding on the second data, but instead directly transmits the second data in the (N+1)th time-domain unit. The second data is the data to be transmitted in the (N+1)th time-domain unit. For example, as shown in Figure 8, the (N+1)th time-domain unit is symbol group 4, and the first communication device transmits the second data in symbol group 4.

[0219] Optionally, the first communication device is a first terminal device, which sends the second data to the network device in the N+1 time domain unit. Alternatively, the first terminal device sends the second data to a third terminal device in the N+1 time domain unit.

[0220] It should be noted that the steps 606 to 607 are described by taking the N+1 time domain unit as an example to introduce some possible implementation of the first communication device. In actual application, the first communication device can also determine more time domain units after the N+1 time domain unit, and perform corresponding data transmission. For example, the first communication device determines the N+2 time domain unit according to the N and the first resource, and transmits corresponding data on the N+2 time domain unit.

[0221] Another possible implementation of the steps 608 to 609 is introduced as follows. Optionally, the embodiment shown in FIG. 6 further includes the steps 608 to 609. The steps 608 to 609 can be performed after the step 605.

[0222] 608. The first communication device determines the N+1 time domain unit to the M time domain unit according to the N and the first resource.

[0223] Wherein, N+1

[0224] 609. The first communication device transmits the third data on the N+1 time domain unit to the M time domain unit respectively.

[0225] Specifically, the first communication device does not perform time domain precoding on the third data, but transmits the third data on each time domain unit in the N+1 time domain unit to the M time domain unit. For example, as shown in FIG. 7, the N+1 time domain unit to the 2N time domain unit includes the time slot S4, the time slot S5 and the time slot S6. The first communication device transmits the third data on the time slot S4, the time slot S5 and the time slot S6. For another example, as shown in FIG. 8, the N+1 time domain unit to the 2N time domain unit includes the symbol 7 to the symbol 13. The first communication device transmits the third data on each symbol in the symbol 7 to the symbol 13.

[0226] In the embodiments of the present application, the first communication device receives first information, the first information indicating N time domain units in which data is repeatedly transmitted, N being an integer greater than 1. Then, the first communication device determines, according to N and a first resource, a first time domain unit to an Nth time domain unit, the first resource including the first time domain unit to the Nth time domain unit, the first time domain unit to the Nth time domain unit including an ith time domain unit, 1≤i≤N, i being an integer. The first communication device receives second information, the second information indicating a first factor to an Nth factor, the first factor to the Nth factor including the ith factor, the ith factor corresponding to to-be-transmitted data of the ith time domain unit. The first communication device performs time domain precoding on first data according to the first factor to the Nth factor, to obtain a first time domain precoding data to an Nth time domain precoding data. The first data is to-be-transmitted data of each time domain unit in the first time domain unit to the Nth time domain unit. The first communication device transmits the first time domain precoding data to the Nth time domain precoding data on the first time domain unit to the Nth time domain unit, respectively. The first communication device performs time domain precoding on data in each time domain unit in the first time domain unit to the Nth time domain unit through the first factor to the Nth factor, which is conducive to further suppressing signal interference between users. For example, two communication devices in a communication system can perform the above technical solutions, respectively, so as to avoid or reduce signal interference between the two communication devices when the two communication devices transmit data in the first time domain unit to the Nth time domain unit.

In addition to the at least one of the first information, the third information and the fourth information indicated by the second communication device, other information of the first information, the third information and the fourth information can be specified by a communication protocol, or predefined, or preconfigured, which is not limited in the application. Alternatively, the step 601, the step 601a and the step 601c can be replaced by: the second communication device sends the first communication device at least one of the following: the first information, the third information, or the fifth information. In addition to the at least one of the first information, the third information and the fifth information indicated by the second communication device, other information of the first information, the third information and the fifth information can be specified by a communication protocol, or predefined, or preconfigured, which is not limited in the application. The step 602 is replaced by: the first communication device determines the first time domain unit to the Nth time domain unit according to the at least one of the first information, the third information and the fourth information and the first resource. For example, the second communication device sends the first communication device the first information, and the third information and the fourth information are specified by a communication protocol. Then the first communication device determines the first time domain unit to the Nth time domain unit according to the first information, the third information and the fourth information specified by the communication protocol and the first resource. Alternatively, the first communication device determines the first time domain unit to the Nth time domain unit according to the at least one of the first information, the third information and the fifth information and the first resource. For example, the second communication device sends the first communication device the first information, and the third information and the fifth information are specified by a communication protocol. Then the first communication device determines the first time domain unit to the Nth time domain unit according to the first information, the third information and the fifth information specified by the communication protocol and the first resource.
