[0002] The advancement of communication technology has placed higher demands on the robustness of data transmission. Currently, network devices use the same frequency domain transmission resources to transmit data in different time units, but the quality of the frequency domain transmission resources corresponding to different time units varies. Furthermore, different network devices use different channels to transmit data to terminal devices, and the frequency domain transmission resources between channels vary significantly. Therefore, using the same frequency domain transmission resources during data transmission is inappropriate.

[0084] The technical solution in this application will be described below with reference to the accompanying drawings.

[0085] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, universal mobile telecommunication system (UMTS), fifth generation (5G) system or new radio (NR), etc.

[0086] It should be understood that the network device in the communication system can be any device with wireless transceiver function or a chip that can be set in the device, and the device includes but is not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home base station (for example, Home evolved NodeB, or Home Node B, HNB), Base Band Unit (BBU), Access Point (AP) in Wireless Fidelity (WIFI) system, wireless relay node, wireless backhaul node, transmission point (TP) or transmission sending and receiving point (TP) It can also be a gNB in ​​a 5G system such as NR, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU).

[0087] In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include a radio unit (RU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU implements radio resource control (RRC) and packet data convergence protocol (PDCP) layer functions, while the DU implements radio link control (RLC), media access control (MAC), and physical (PHY) layer functions. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling or PDCP layer signaling, can also be considered to be sent by the DU, or by both the DU and the RU. It is understood that a network device can be a CU node, a DU node, or a device that includes both a CU node and a DU node. Furthermore, the CU can be classified as a network device in the access network (RAN) or a network device in the core network (CN), without limitation here.

[0088] It should also be understood that the terminal device in the communication system may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal device in the embodiment of the present application may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiment of the present application does not limit the application scenario.

[0089] To facilitate understanding of the embodiments of the present application, several terms involved in the present application are first briefly explained.

[0090] 1. Transmission Configuration Indicator (TCI state): The TCI state is used to indicate the quasi-co-location (QCL) relationship between the large-scale channel parameters of the data transmission process and one or two downlink reference signals. Thus, the terminal can obtain the indication information of the large-scale channel parameter relationship of the received signal based on the TCI state, and then demodulate the data carried by the signal based on channel estimation. Each TCI state may include the serving cell index (ServeCellIndex), the bandwidth part (BWP) identifier (ID), and the reference signal resource identifier. The reference signal resource identifier can be, for example, at least one of the following: a non-zero power (NZP) CSI-RS reference signal resource identifier (NZP-CSI-RS-ResourceId), a non-zero power CSI-RS reference signal resource set identifier (NZP-CSI-RS-ResourceSetId), or an SSB index (SSB-Index). Different TCI states correspond to different TRPs in the following expressions.

[0091] 2. Sounding Reference Signal Resource Index (SRI): This is a resource identifier for the sounding reference signal (SRS). It can be used as a reference for the UE when sending the physical uplink shared channel (PUSCH).

[0092] 3. Quasi co-located (QCL): The QCL relationship is used to indicate that multiple resources have one or more identical or similar communication characteristics. For example, if two antenna ports have a quasi co-located relationship, the large-scale characteristics of the channel for transmitting a signal on one port can be inferred from the large-scale characteristics of the channel for transmitting a signal on the other port. The signals corresponding to the antenna ports with a QCL relationship have the same parameters, or the parameters of one antenna port can be used to determine the parameters of another antenna port with a QCL relationship with the antenna port, or the two antenna ports have the same parameters, or the parameter difference between the two antenna ports is less than a certain threshold. The parameters may include one or more of the following large-scale channel parameters: delay spread, Doppler spread, Doppler shift, average delay, average gain, and spatial Rx parameters. Among them, the spatial reception parameters may include one or more of the following: transmission angle (Angle of arrival, AOA), main transmission angle (Dominant AoA), average arrival angle (Average AoA), arrival angle (Angle of departure, AOD), channel correlation matrix, power angle spread spectrum of arrival angle, average trigger angle (Average AoD), power angle spread spectrum of departure angle, transmission channel correlation, reception channel correlation, transmission beamforming, reception beamforming, spatial channel correlation, spatial filter, or spatial filtering parameters, or spatial reception parameters.

[0093] 4. Time domain / time unit: includes at least multiple time sampling points and can be a frame, radio frame, system frame, subframe, half-frame, time slot, mini-time slot, symbol, etc. In the following expressions, the time domain / time unit is represented by "slot".

[0094] 5. Data: can refer to codeword, transport block, code block, or code block group.

[0095] 6. Frequency domain resources: The frequency domain resources mentioned in the embodiments of the present application may refer to physical frequency domain resources or virtual frequency domain resources.

[0096] In addition, in order to facilitate understanding of the embodiments of the present application, the following explanations are made.

[0097] First, for ease of description, in this application, when numbering, consecutive numbers may be used starting from 0. For example, the 0th symbol in a time slot may refer to the first symbol in that time slot. Of course, this is not a limitation in the specific implementation. For example, consecutive numbering may also start from 1. For example, the 1st symbol in a time slot may also refer to the first symbol in that time slot. Due to different starting values ​​for numbering, the same symbol will have different numbers in the time slot.

[0098] It should be understood that the above descriptions are all made for the purpose of describing the technical solutions provided by the embodiments of the present application, and are not intended to limit the scope of the present application.

[0099] Second, the first, second, and various numerical numbers in the embodiments shown below are merely distinctions for ease of description and are not intended to limit the scope of the embodiments of the present application, for example, to distinguish between different frequency domain resources, different TCI states, and so on.

[0100] Third, in the embodiments described below, "pre-acquisition" may include being indicated by network device signaling or being pre-defined, such as by a protocol definition. "Pre-definition" may be achieved by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in devices (e.g., including terminal devices and network devices). This application does not limit the specific implementation method.

[0101] Fourth, the term "storage" used in the embodiments of this application may refer to storage in one or more memories. The one or more memories may be provided separately or integrated into an encoder or decoder, a processor, or a communication device. The one or more memories may also be provided in part separately and in part integrated into a decoder, a processor, or a communication device. The memory may be any type of storage medium, and this application is not limited thereto.

[0102] Fifth, the "protocol" involved in the embodiments of the present application may refer to a standard protocol in the communication field, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems. This application does not limit this.

[0103] Sixth, "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c. Where a, b and c can be single or multiple, respectively.

[0104] To facilitate understanding of the embodiments of the present application, Figure 1 The communication system shown is used as an example to describe in detail a communication system applicable to the data transmission method provided in the embodiment of the present application. Figure 1 A schematic diagram of a communication system 100 applicable to the method for sending and receiving data according to an embodiment of the present application is shown. As shown in the figure, the communication system 100 may include at least one terminal device, such as terminal device 101 shown in the figure; the communication system 100 may also include at least one network device, such as network device #1 102 or network device #2 103 shown in the figure.

[0105] Optionally, the communication system 100 may include multiple network devices, such as network device #1 102 and network device #2 103 shown in the figure. Network device #1 102 and network device #2 103 may be network devices in the same cell or in different cells, and this application is not limited thereto. The figure is merely an example, showing an example where network device #1 102 and network device #2 103 are located in the same cell.

[0106] At present, network devices use the same frequency domain resources to transmit data in different time units, but the quality of the frequency domain resources corresponding to different time units is different. More obviously, different network devices use different channels to transmit data to terminal devices. The frequency domain resources between channels have obvious differences. Therefore, it is inappropriate to use the same frequency domain resources during data transmission.

[0107] Therefore, a frequency domain resource allocation scheme in which frequency domain resource indications are associated with TCI states is proposed. A terminal device receives indication information, where the indication information includes N frequency domain resource indications, each of which is associated with one or more transmission configuration indication states (TCI States), each TCI state corresponds to multiple transmission time units, and each frequency domain resource indication is used to indicate a frequency domain transmission resource within each of the multiple transmission time units corresponding to its associated TCI State; wherein, among the frequency domain transmission resources indicated by the N frequency domain resource indications, at least two frequency domain transmission resources are different, and N is an integer equal to or greater than 1; and the frequency domain transmission resources indicated by the N frequency domain resource indications are determined.

[0108] Figure 2 This is a schematic flow chart of a method 200 for data transmission provided by an embodiment of the present application, from the perspective of device interaction. As shown in the figure, the method 200 may include steps 210 and 220. Each step in the method 200 is described in detail below.

[0109] It should be noted that the data transmission method provided in this application can be applied to wireless communication systems, for example, Figure 1 In the communication system 100 shown in FIG. , there may be a wireless communication connection relationship between the communication devices in the communication system. For example, Figure 1 The terminal device 101 shown in the figure can respectively have wireless communication connection relationships with network device #1 102 and network device #2 103. The backhaul link between network device #1 102 and network device #2 103 can be an ideal backhaul link or a non-ideal backhaul link, which is not limited in this application.

[0110] The network devices shown below may correspond to Figure 1 It should be understood that in the embodiments shown below, network device #1 102 and / or network device #2 103 configure frequency domain transmission resources for terminal device 101.

[0111] In step 210, the terminal device receives the instruction information from the network device. Accordingly, the network device sends the instruction information to the terminal device.

[0112] Specifically, the indication information includes N frequency domain resource indications, each frequency domain resource indication is associated with one or more transmission configuration indication states TCI State, each TCI state corresponds to multiple transmission time units, and each frequency domain resource indication is used to indicate the frequency domain transmission resources within each transmission time unit in the multiple transmission time units corresponding to its associated TCI State; wherein, among the frequency domain transmission resources indicated by the N frequency domain resource indications, at least two frequency domain transmission resources are different, and N is an integer equal to or greater than 1.

[0113] The following description takes the transmission time unit as a time slot as an example. Those skilled in the art will appreciate that the transmission time unit may also include a symbol, a mini-slot, or a frame.

[0114] Optionally, the indication information includes N frequency domain indication fields, which are used to carry N frequency domain resource indications. An example is, Figure 3 As shown, taking two frequency domain indication domains as an example, they are respectively recorded as frequency domain indication domain 1 and frequency domain indication domain 2, frequency domain indication domain 1 is used to indicate frequency domain transmission resource 1, and frequency domain indication domain 2 is used to indicate frequency domain transmission resource 2. Or, frequency domain indication domain 1 is used to indicate frequency domain transmission resource 1, and frequency domain indication domain 2 indicates a numerical value, and frequency domain transmission resource 2 is determined based on frequency domain transmission resource 1 and the numerical value. The indication of frequency domain indication domain 1 is associated with TCI state1, and the transmission time units corresponding to TCI state1 are slot1 and slot3; the indication of frequency domain indication domain 2 is associated with TCI state2, and the transmission time units corresponding to TCI state2 are slot2 and slot4. Another example is, Figure 5 As shown in the figure, taking two frequency domain indication fields as an example, they are respectively denoted as frequency domain indication field 1 and frequency domain indication field 2. Frequency domain indication field 1 is used to indicate frequency domain transmission resource 1, and frequency domain indication field 2 is used to indicate frequency domain transmission resource 2. The indication of frequency domain indication field 1 is associated with TCI state 1 and TCI state 2, and the transmission time units corresponding to TCI state 1 and TCI state 2 are slot 1 and slot 3; the indication of frequency domain indication field 2 is associated with TCI state 3, and the transmission time units corresponding to TCI state 3 are slot 2 and slot 4.

[0115] Optionally, the indication information includes 1 frequency domain indication field, which is used to carry N frequency domain resource indications. An example is, Figure 4As shown, one frequency domain indication field indicates both frequency domain transmission resource 1 and frequency domain transmission resource 2. The indication of frequency domain indication field 1 is associated with TCI state 1, and the transmission time units corresponding to TCI state 1 are slot 1 and slot 3; the indication of frequency domain indication field 2 is associated with TCI state 2, and the transmission time units corresponding to TCI state 2 are slot 2 and slot 4. Another example is, Figure 6 As shown in the figure, one frequency domain indication field simultaneously indicates frequency domain transmission resource 1 and frequency domain transmission resource 2. The indication of frequency domain indication field 1 is associated with TCIstate1 and TCIstate2, and the transmission time units corresponding to TCIstate1 and TCIstate2 are slot1 and slot3; the indication of frequency domain indication field 2 is associated with TCIstate3, and the transmission time units corresponding to TCIstate3 are slot2 and slot4.

[0116] In a possible implementation, without considering the frequency domain offset (offet) or uniformly configuring or assuming the frequency domain offset is 0 from another perspective, in order to implement frequency hopping between different network devices, the frequency domain transmission resource 1 and the frequency domain transmission resource 2 indicated by the frequency domain resource are different frequency domain transmission resources. Figure 7 As shown, the frequency domain transmission resource used for data transmission in transmission time units slot 1 and slot 3 corresponding to TCI state 1 is frequency domain transmission resource 1, and the frequency domain transmission resource used for data transmission in transmission time units slot 2 and slot 4 corresponding to TCI state 2 is frequency domain transmission resource 2. It can be seen that in this embodiment, during data transmission, different frequency domain transmission resources are used for data transmission in transmission time units corresponding to different TCI states.

[0117] In another possible implementation, the frequency domain transmission resource 1 and the frequency domain transmission resource 2 indicated by the frequency domain resource are the same frequency domain transmission resource, and the first slot at which each network device starts transmitting (such as the first slot of network device 1 corresponding to TCI state1 is slot1, and the first slot of network device 2 corresponding to TCI state2 is slot2) does not involve a frequency domain offset or can be considered to have a frequency domain offset of 0. Except for the first slot corresponding to each network device, the frequency domain offsets corresponding to other slots are the same and not 0. Then Figure 8As shown, the frequency domain transmission resource used by transmission time unit slot 1 corresponding to TCI state 1 to transmit data is frequency domain transmission resource 1. The frequency domain transmission resource used by transmission time unit slot 3 corresponding to TCI state 1 to transmit data is determined by frequency domain transmission resource 1 and the frequency domain offset. The frequency domain transmission resource used by transmission time unit slot 2 corresponding to TCI state 2 to transmit data is frequency domain transmission resource 2. The frequency domain transmission resource used by transmission time unit slot 4 corresponding to TCI state 2 to transmit data is determined by frequency domain transmission resource 2 and the frequency domain offset. Optionally, the frequency domain offsets corresponding to other slots are different. Optionally, the frequency domain offset corresponding to each time domain unit can be uniformly configured by the network device as a common frequency domain offset, or configured separately for different time domain units by the network device. It can also be specified by the protocol, for example, that different offset adjustment coefficients (e.g., 0, 1, etc.) correspond to the parity of the slot number. After the network device configures the frequency domain offset, the terminal device calculates the corresponding offset based on the frequency domain offset and the offset adjustment coefficient. It can be seen that in this implementation, during data transmission, the frequency domain transmission resources used by the transmission time units corresponding to the same TCI state are different.

[0118] In another possible implementation, the frequency domain resource indication only indicates one frequency domain transmission resource 1, such as Figure 9As shown, the transmission time units corresponding to TCI state 1 are slot 1, slot 2, slot 3, and slot 4. The frequency domain transmission resource used for data transmission in slot 1 is frequency domain transmission resource 1. The frequency domain transmission resource used for data transmission in transmission time unit slot 2 corresponding to TCI state 1 is determined by frequency domain transmission resource 1 and a frequency domain offset. The frequency domain transmission resources used for data transmission in transmission time units slot 3 and slot 4 corresponding to TCI state 1 are determined in the same manner as the frequency domain transmission resources determined for slot 1 and slot 2. The offset can be determined based on the even-odd rule of the slot number. For example, the offset adjustment coefficient for odd-numbered slots is 0, and the offset adjustment coefficient for even-numbered slots is 1. If a network device is configured with a uniform offset value, such as X, the offset in odd-numbered slots is 0, and the offset in even-numbered slots is X. Of course, other rules can also be used, as long as the frequency domain transmission resources in different slots corresponding to TCI state 1 are frequency-hopped (i.e., not completely identical). Optionally, the frequency domain offsets corresponding to other slots can be uniformly configured by the network device as a common frequency domain offset or separately configured by the network device for different time domain units. It can be seen that in this embodiment, when data is transmitted, the frequency domain transmission resources used by adjacent transmission time units corresponding to the same TCIstate are different.

[0119] In another possible implementation, the frequency domain transmission resource 1 and the frequency domain transmission resource 2 indicated by the frequency domain resource are different frequency domain transmission resources, and the first slot at which each network device starts transmitting (such as the first slot of network device 1 corresponding to TCI state1 is slot1, and the first slot of network device 2 corresponding to TCI state2 is slot2) does not involve a frequency domain offset or can be considered to have a frequency domain offset of 0. Except for the first slot corresponding to each network device, the frequency domain offsets corresponding to other slots are different and not 0. Then Figure 10As shown, the frequency domain transmission resource used by transmission time unit slot 1 corresponding to TCI state 1 to transmit data is frequency domain transmission resource 1, and the frequency domain transmission resource used by transmission time unit slot 3 corresponding to TCI state 1 to transmit data is determined by frequency domain transmission resource 1 and frequency domain offset 1. The frequency domain transmission resource used by transmission time unit slot 2 corresponding to TCI state 2 to transmit data is frequency domain transmission resource 2, and the frequency domain transmission resource used by transmission time unit slot 4 corresponding to TCI state 2 to transmit data is determined by frequency domain transmission resource 2 and frequency domain offset 2. Optionally, the frequency domain offsets corresponding to other slots are the same and not zero. Optionally, the frequency domain offset corresponding to each time domain unit can be uniformly configured by the network device as a common frequency domain offset, or configured by the network device for different time domain units. It can also be specified by the protocol, for example, that different offset adjustment coefficients (e.g., 0, 1, etc.) correspond to the parity of the slot number. After the network device configures the frequency domain offset, the terminal device calculates the frequency domain offset and the offset adjustment coefficient to obtain the corresponding offset. It can be seen that in this implementation, during data transmission, the frequency domain transmission resources used by the transmission time units corresponding to the same TCI state are different; and the frequency domain transmission resources used by the transmission time units corresponding to different TCI states are different.

[0120] For the convenience of distinction and explanation, in step 210, at least two frequency-domain transmission resources are different, including: at least two frequency-domain transmission resources in multiple transmission time units corresponding to the same TCIstate are different.

[0121] like Figure 8 As shown, taking the transmission time units slot1 and slot3 corresponding to TCI state1 as an example, the frequency domain transmission resources in slot1 and slot3 are different, that is, the frequency domain transmission resources of the transmission time unit slot1 corresponding to TCI state1 are f2-f4, and the frequency domain transmission resources of the transmission time unit slot3 corresponding to TCI state1 are f1-f3.

[0122] At least two frequency domain transmission resources are different, including: among the frequency domain transmission resources in a transmission time unit corresponding to different TCI States, at least two frequency domain transmission resources are different.

[0123] like Figure 6As shown, taking the transmission time unit slot1 corresponding to TCI state1 and the transmission time unit slot2 corresponding to TCI state2 as examples, the frequency domain transmission resources in slot1 and slot2 are different, that is, the frequency domain transmission resources of the transmission time unit slot1 corresponding to TCI state1 are f2-f4, and the frequency domain transmission resources of the transmission time unit slot2 corresponding to TCI state2 are f1-f3.

[0124] At least two frequency domain transmission resources are different, including: at least two frequency domain transmission resources in multiple transmission time units corresponding to the same TCI state are different, and at least two frequency domain transmission resources in a transmission time unit corresponding to different TCI States are different.

[0125] like Figure 9 As shown in the figure, taking the transmission time units slot1 and slot3 corresponding to TCI state1 and the transmission time units slot2 and slot4 corresponding to TCI state2 as examples, the frequency domain transmission resources in the transmission time units slot1 and slot3 corresponding to TCI state1 are different, that is, the frequency domain transmission resources of the transmission time unit slot1 corresponding to TCI state1 are f4-f8, and the frequency domain transmission resources of the transmission time unit slot3 corresponding to TCI state1 are f3-f7. The frequency domain transmission resources in the transmission time units slot2 and slot4 corresponding to TCI state2 are different, that is, the frequency domain transmission resources of the transmission time unit slot2 corresponding to TCI state2 are f2-f6, and the frequency domain transmission resources of the transmission time unit slot4 corresponding to TCI state2 are f1-f5. The frequency domain transmission resources of the transmission time unit slot1 corresponding to TCI state1 are f4-f8, and the frequency domain transmission resources of the transmission time unit slot2 corresponding to TCI state2 are f2-f6.

[0126] Optionally, the TCI states associated with the same frequency domain resource indication belong to a TCI state group; the TCI state group is divided according to a predetermined grouping rule or configured by a network device. Optionally, the indication information is downlink control information DCI.

[0127] In step 220, the terminal device determines the frequency domain transmission resources indicated by the N frequency domain resource indications.

[0128] Optionally, the frequency domain resource indication is used to directly indicate the frequency domain transmission resource or indirectly indicate the frequency domain transmission resource.

[0129] In a possible implementation, the frequency domain resource indication is used to directly indicate the frequency domain transmission resource. The terminal device directly transmits data according to the frequency domain transmission resource indicated by the frequency domain resource indication.

[0130] In another possible implementation, the frequency domain resource indication is used to indirectly indicate the frequency domain transmission resource. The frequency domain resource indication indicates the frequency domain transmission resource, and the frequency domain transmission resources indicated by the N frequency domain resource indications are determined based on the frequency domain transmission resource indicated by the frequency domain resource indication and the frequency domain offset corresponding to each time domain unit in the multiple time domain units corresponding to the associated TCIstate.

[0131] For different network devices, the frequency domain transmission resources configured for the terminal device can be the same or different. The frequency domain offset corresponding to each time domain unit can be uniformly configured or individually configured by high-level signaling, and the configured frequency domain offsets can be the same or different.

The indication information is used to indicate a second frequency domain transmission resource for downlink data transmission by at least one second network device, where the second frequency domain transmission resource is different from the first frequency domain transmission resource for downlink data transmission by the first network device. The second frequency domain transmission resource is a frequency domain transmission resource for downlink data transmission by the at least one second network device within multiple second transmission time units corresponding to its corresponding second transmission configuration indication state TCI state, where each second network device corresponds to a TCI state, and each TCI state corresponds to multiple second transmission time units. The first frequency domain transmission resource is a frequency domain transmission resource for downlink data transmission by the first network device for a terminal device within multiple first transmission time units corresponding to its corresponding first TCI state.

[0144] Optionally, the second frequency domain transmission resource is different from the first frequency domain transmission resource for downlink data transmission of the first network device, including that the second frequency domain transmission resource in each second transmission time unit is different from the first frequency domain transmission resource in each first transmission time unit, or is partially different.

[0145] Optionally, the first network device receives a second TCI state corresponding to at least one second network device, and the second network device sends the second TCI state corresponding to the second network device to the first network device.

[0146] In step 420, the first network device sends the indication information to the at least one second network device.

As shown in the figure, the method 500 may include steps 510 and 520. Each step in the method 500 is described in detail below.

[0148] In step 510, the first network device generates indication information, where the indication information is used to indicate a second frequency domain transmission resource for at least one second network device to perform uplink data transmission, where the second frequency domain transmission resource is different from the first frequency domain transmission resource for the first network device to perform uplink data transmission; wherein the second frequency domain transmission resource is a frequency domain transmission resource for at least one second network device to perform uplink data transmission within a plurality of second transmission time units corresponding to its corresponding second sounding reference signal resource index SRI, each second network device corresponds to an SRI, and each SRI corresponds to a plurality of second transmission time units; the first frequency domain transmission resource is a frequency domain transmission resource for the first network device to perform uplink data transmission for the terminal device within a plurality of first transmission time units corresponding to its corresponding first SRI; the first network device sends the indication information to the at least one second network device.
