The first relation obtained through the determination in the embodiment of the present application can be used to determine PUSCH transmission information corresponding to each TCI state, so as to perform data transmission, and solve the technical problem that the current PUSCH transmission method for multiple access network devices based on the TCI state and/or the unified TCI state is not applicable.

For example, at least one (one) of a, b or c may represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", wherein a, b, c may be single or plural.

The method provided by the application can be applied to various communication systems, such as an internet of things (internet of things, ioT) system, a narrowband internet of things (narrow band internet of things, NB-IoT) system, a long term evolution (long term evolution, LTE) system, a fifth generation (5G) communication system, a new communication system (such as 6G) in future communication development, and the like.

The technical solutions provided herein may also be applied to machine-type communication (machine type communication, MTC), inter-machine communication long term evolution technology (long term evolution-machine, LTE-M), device-to-device (D2D) networks, machine-to-machine (machine to machine, M2M) networks, internet of things (internet of things, ioT) networks, or other networks. The IoT network may include, for example, an internet of vehicles.

In some deployments, a base station (e.g., gNB) may be composed of a Centralized Unit (CU) and a Distributed Unit (DU). Namely, the functions of the base stations in the access network are split, part of the functions of the base stations are deployed on one CU, and the rest of the functions are deployed on DUs. And a plurality of DUs share one CU, so that the cost can be saved, and the network expansion is easy. In other deployments of base stations, CUs may also be divided into CU-Control Plane (CP) and CU-User Plane (UP), etc. In yet other deployments of base stations, the base stations may also be open radio access network (open radio access network, ora) architecture, etc., the application is not limited to a particular type of base station.

In the communication system shown in fig. 1, three base stations and six UEs are included, such as base station 1 to base station 3 and UE1 to UE6 in fig. 1. In this communication system, for example, taking UE1 as an example, data transmission between UE1 and base stations 1 to 3 is described, one or more of base stations 1 to 3 may transmit downlink signals such as configuration information or downlink control information (downlink control information, DCI) to UE1, and UE1 may transmit uplink signals such as SRS or physical uplink shared channel (physical uplink shared channel, PUSCH) to one or more of base stations 1 to 3. It will be appreciated that for any one of UEs 2 to 6, reference may be made to the above description for the manner of communication with one or more of base stations 1 to 3, and this will not be described in detail here.

The plurality of antennas may include at least one transmitting antenna for transmitting signals, at least one receiving antenna for receiving signals, and the like, and the specific structure of each communication device is not limited in the embodiments of the present application. Optionally, the communication system may further include a network controller, a mobility management entity, and other network entities, where embodiments of the present application are not limited.

It will be appreciated that the method provided in the present application may be applied not only to the communication system shown in fig. 1, but also to the communication systems shown in other figures, which is not limited in this embodiment of the present application.

Before describing the methods of the present application in detail, some concepts related to the present application will be briefly described.

Time division transmission, which is understood to mean the transmission of signals/channels on different time resources.

Frequency division transmission may be understood as transmission of signals/channels on the same time resources but different frequency domain resources and/or transmission on partly the same time resources but different frequency domain resources.

Space division transmission is understood to mean that signals/channels are transmitted on the same time resource and the same frequency domain resource, but that signals/channels belong to different transport layers or to different redundancy versions (redundancy version, RV) of the same transport block.

In the current data transmission method, in a scenario of data transmission for a single access network device, a terminal may obtain spatial information and/or power control parameters of a PUSCH based on a TCI state and/or a unified TCI state, and perform data transmission based on the spatial information and/or the power control parameters of the PUSCH. However, in the scenario of data transmission for multiple access network devices, the above data transmission method is no longer applicable, that is, the terminal cannot obtain spatial information and/or power control parameters of PUSCH based on TCI state and/or unified TCI state, so as to perform data transmission.

Aiming at the technical problem that the current TCI state and/or unified TCI state-oriented PUSCH transmission method for a plurality of access network devices is not applicable, in the embodiment of the application, a new data transmission method is provided, and the data transmission can be performed based on the PUSCH transmission information corresponding to each TCI state under the scene of data transmission for a plurality of access network devices, so that the technical problem that the current TCI state and/or unified TCI state-oriented PUSCH transmission method for a plurality of access network devices is not applicable is solved.

Note that the TCI state mentioned in the present application may be a unified TCI state in Release 17 (R17), or may be a unified TCI state of other protocol versions, which is not specifically limited herein.

In some possible implementations, the unified TCI state function may include a common TCI state (Joint) mechanism for downlink and uplink, optionally, other terms may be used, such as a first mechanism, etc., which is not specifically limited by the present application and is described below in terms of the Joint mechanism), and/or different TCI states (Separate) for downlink and uplink, optionally, other terms may be used, such as a second mechanism, etc., which is not specifically limited by the present application and is described below in terms of the Separate mechanism.

The join mechanism may refer to a TCI state applicable to some or all of the downlink channels/signals and some or all of the uplink channels/signals. The separation mechanism may refer to two TCI states being applicable to part or all of the downstream channels/signals and part or all of the upstream channels/signals, respectively. For the join mechanism, it is also understood that one TCI state of the network indication/network configuration/protocol specification may apply to some or all of the downstream channels/signals, and some or all of the upstream channels/signals. For the separation mechanism, it is also understood that a TCI state of the network indication/network configuration/protocol specification applies to some or all of the downstream channels/signals or to some or all of the upstream channels/signals.

Referring to fig. 2, fig. 2 is a flow chart of a data transmission method according to an embodiment of the present application. The data transmission method is applied to the technical field of communication, and comprises the following steps:

s201: the network device sends at least one TCI state and/or a first relation to the terminal device, and the terminal device receives the at least one TCI state and/or the first relation sent by the network device.

The first relation includes a corresponding relation between PUSCH transmission information of a physical uplink shared channel and a TCI state. The PUSCH transmission information may specifically include information of a time domain resource and/or a frequency domain resource and/or a transmission layer of the PUSCH, may also include information of transmission timing, and may also include parameters related to PUSCH transmission, such as: modulation coding scheme (modulation coding scheme, MCS), redundancy version (redundancy version, RV), number of layers, time domain resource, frequency domain resource, spatial information, and the like. The PUSCH transmission information may also be related information for PUSCH transmission, and is not particularly limited herein.

Alternatively, the first relationship need not necessarily be sent by the network device. When the terminal device obtains the first relationship based on the second relationship and/or the third relationship, or when the terminal device obtains the first relationship based on the protocol specification, the network device does not need to send the first relationship to the terminal device. As to how the terminal device determines the first relationship, refer to step S202 described below, which is not described here.

It can be understood that the terminal device in the embodiment of the present application may be a device with a processor for executing an instruction executed by a computer, which may be a handheld terminal (such as a mobile phone, a tablet computer, etc.), or may be a vehicle-mounted terminal (such as a wireless terminal in an unmanned plane, etc.), and specifically may be the terminal device in fig. 1 (including, but not limited to, any one of the devices such as UE1 to UE 6) described above, which is used to execute the data transmission method in the embodiment of the present application, so as to solve the technical problem that the PUSCH transmission method for multiple access network devices based on the TCI state and/or the unified TCI state is not applicable at present.

The network device in this embodiment of the present application is a device on which a processor capable of executing instructions by using a computer is mounted, and may be an access network device (such as a base station, a transmission point TRP, etc.), specifically may be an access network device in fig. 1 (including, but not limited to, any one of the base stations 1 to 3) described above, and is configured to execute a data transmission method in this embodiment of the present application, so as to solve a technical problem that a PUSCH transmission method for multiple access network devices based on a TCI state and/or a unified TCI state is not applicable at present.

S202: and the terminal equipment determines the PUSCH transmission information corresponding to the at least one TCI state based on the at least one TCI state and/or the first relation.

Alternatively, this step S202 may be an optional step.

It may be understood that, whether or not the step S202 is performed, the terminal device may directly perform data transmission based on the PUSCH transmission information corresponding to each obtained TCI state, without limiting that the embodiment of the present application must actually perform the step S202.

For example, when the first relationship includes a correspondence between the TCI state and PUSCH transmission information, in this case, step S202 may be an optional step, that is, whether or not step S202 is performed, the terminal device may directly obtain PUSCH transmission information corresponding to each TCI state based on the first relationship, so as to perform data transmission.

It should be understood that the above exemplary case is only described as one possible application case where step S202 is an optional step, and the embodiment of the present application should not be limited to the above exemplary case, and optionally, there may be other possible application cases where step S202 is an optional step, which is not exhaustive in the embodiment of the present application.

In a possible embodiment, the terminal device may determine the above-mentioned first relationship based on the second relationship and/or the third relationship.

The second relation includes a correspondence between PUSCH transmission information and a sounding reference signal SRS resource set, and the third relation includes a correspondence between SRS resource set and TCI state.

The terminal device may determine a correspondence between PUSCH transmission information and a TCI state based on a correspondence between PUSCH transmission information and a sounding reference signal SRS resource set, and a correspondence between SRS resource set and a TCI state.

It will be appreciated that in case the first relationship is determined based on the second relationship and/or the third relationship, or in case the first relationship is determined based on the protocol specification, the network device does not need to send the first relationship to the terminal device.

The first relation obtained through the determination in the embodiment of the present application may be used to determine PUSCH transmission information corresponding to each TCI state, so as to perform data transmission, and solve the technical problem that the current PUSCH transmission method for multiple access network devices based on the TCI state and/or the unified TCI state is not applicable.

Optionally, the third relationship and/or the second relationship may be determined through RRC messages, MAC signaling, and/or DCI messages or signaling or information sent by the network side, or may be determined through content specified by a protocol, which is not limited in the embodiments of the present application.

Through the embodiment of the application, the third relationship and/or the second relationship can be determined based on various modes, and the third relationship and/or the second relationship are used for determining to obtain the first relationship so as to support PUSCH transmission based on the TCI state and oriented to a plurality of access network devices.

Mode one:

the network device issues at least one message or signaling or information of RRC message, MAC signaling and DCI information to the terminal device. Correspondingly, the terminal equipment receives at least one message or signaling or information from the RRC message, the MAC signaling and the DCI information of the network equipment, and obtains the third relation and/or the second relation according to the RRC message and/or the MAC signaling and/or the DCI information.

Illustratively, the following description will be given by taking a case in which the third relationship is determined by MAC signaling as an example.

The network device sends the MAC signaling to the terminal device, and correspondingly, the terminal device receives the MAC signaling from the network device. At this time, the correspondence between each SRS resource set included in the third relationship and the TCI state may be determined by a bit of the MAC signaling.

For example, in a PUSCH transmission scenario based on the TCI state and facing to a plurality of access network devices, the corresponding relation between the first SRS resource set and the TCI state and/or the corresponding relation between the second SRS resource set and the TCI state, which are included in the third relation, are determined by bits of the MAC signaling.

When the value of the first bit of the MAC signaling is 0, the first SRS resource set included in the third relation corresponds to the first TCI state, and when the value of the first bit of the MAC signaling is 1, the first SRS resource set included in the third relation corresponds to the second TCI state; and/or, in the case that the value of the second bit of the MAC signaling is 0, the second SRS resource set included in the third relation corresponds to the first TCI state, and in the case that the value of the second bit of the MAC signaling is 1, the second SRS resource set included in the third relation corresponds to the second TCI state.

Or when the value of the first bit of the MAC signaling is 0, the SRS resource set corresponding to the first bit corresponds to the first TCI state, and when the value of the first bit of the MAC signaling is 1, the SRS resource set corresponding to the first bit corresponds to the second TCI state; and/or, when the value of the second bit of the MAC signaling is 0, the SRS resource set corresponding to the second bit corresponds to the second TCI state, and when the value of the second bit of the MAC signaling is 1, the SRS resource set corresponding to the second bit corresponds to the first TCI state. It can be appreciated that the SRS resource set corresponding to the first bit can be the first SRS resource set or the second SRS resource set. It can be appreciated that the SRS resource set corresponding to the second bit may be the first SRS resource set or the second SRS resource set.

It should be understood that the first bit and the second bit in the embodiments of the present application are two different bits in MAC signaling.

For example, the first bit may specifically refer to a first bit in the MAC signaling, or may refer to a bit in the MAC signaling for indicating a correspondence between the first SRS resource set and the TCI state; the second bit may specifically refer to a second bit in the MAC signaling, or may refer to a bit in the MAC signaling, which is used to indicate a correspondence between the second SRS resource set and the TCI state, which is not limited in the embodiment of the present application.

It should be understood that the first TCI state and the second TCI state in the embodiments of the present application are two different TCI states in the at least one TCI state.

For example, the first TCI state may specifically be the TCI state of the smaller ID of the at least one TCI state, or may be the first TCI state of the at least one TCI state; the second TCI state may specifically be a TCI state with a larger ID in the at least one TCI state, or may be a second TCI state in the at least one TCI state, which is not limited in this embodiment of the present application.

It is understood that the first TCI state may also be a set of the first TCI states; the second TCI state may also belong to a second set of TCI states. The first set of TCI states and the second set of TCI states may correspond to different TRPs, respectively.

Note that TRP in the present application may be associated with spatial information or null directions (e.g., one or a group of beams); alternatively, TRP may be characterized by spatial information or null directions (e.g., one or a set of beams); alternatively, TRP may be characterized by power control parameters. In addition, the TRP in the present application may be a functional module (for example, implemented by using a software function), or may be implemented by hardware, which is not limited by the implementation of the TRP.

It should be understood that, in the embodiment of the present application, the first SRS resource set may specifically be an SRS resource set with a smaller ID, or may be the first SRS resource set; the second SRS resource set may specifically be an SRS resource set with a larger ID, or may be a second SRS resource set, which is not limited in this embodiment of the present application.

Optionally, each SRS resource set in the embodiments of the present application may include one or more SRS resources, where a use (usage) of the SRS resources may be configured or indicated as a codebook (codebook) or a non-codebook (noncodebook).

Through the embodiment of the application, the corresponding relation between each SRS resource set included in the third relation and the TCI state can be determined based on the bit of the MAC signaling, and further the corresponding relation is used for determining the first relation so as to support PUSCH transmission facing a plurality of access network devices based on the TCI state.

Referring specifically to fig. 3a, fig. 3a is a schematic diagram of a MAC signaling provided in an embodiment of the present application.

As can be seen from fig. 3a, the corresponding relation between each SRS resource set included in the third relation and the TCI state is determined by using the bit of the MAC signaling, such as the bit of the MAC signaling used for updating the SRS path loss reference signal.

Specifically, the correspondence relationship may be determined by using R bits of MAC signaling. For example, if the R bit in the first byte is 0, this indicates that the SRS resource set is associated with the first TCI state, and if the R bit in the first byte is 1, this indicates that the SRS resource set is associated with the second TCI state. It is to be appreciated that the identity of the same path loss reference signal can correspond to the identities of different SRS resource sets, but only one identity of the path loss reference signal can be associated with each of the identities of the SRS resource sets.

Referring to fig. 3b, as can be obtained from fig. 3b, the corresponding relationship between each SRS resource set and the TCI state is determined by using bits of the MAC signaling.

Specifically, the correspondence relationship may be determined by using R bits of MAC signaling. For example, if the first R bit in the second byte is 0, it indicates that its corresponding SRS resource set (i.e., the SRS resource set indicated by the second byte SRS Resource Set ID) is associated with the first TCI state, and if the first R bit in the second byte is 1, it indicates that its corresponding SRS resource set (i.e., the SRS resource set indicated by the second byte SRS Resource Set ID) is associated with the second TCI state. If the first R bit in the third byte is 0, it indicates that its corresponding SRS resource set (i.e. the SRS resource set indicated by the third byte SRS Resource Set ID) is associated with the first TCI state, and if the first R bit in the third byte is 1, it indicates that its corresponding SRS resource set (i.e. the SRS resource set indicated by the third byte SRS Resource Set ID) is associated with the second TCI state.

Mode two:

the terminal device determines the third relationship and/or the second relationship through the content specified by the protocol.

By way of example, the following description will be given taking, as an example, a case where the third relationship is determined by the contents specified by the protocol.

The first SRS resource set included in the third relation corresponds to the first TCI state, the second SRS resource set included in the third relation corresponds to the second TCI state, and/or the first SRS resource set included in the third relation corresponds to the second TCI state, and the second SRS resource set included in the third relation corresponds to the first TCI state.

Through the embodiment of the application, the corresponding relation between each SRS resource set included in the third relation and the TCI state can be determined based on the protocol content, and further the corresponding relation is used for determining the first relation so as to support PUSCH transmission facing a plurality of access network devices based on the TCI state.

In another possible embodiment, the terminal device may directly obtain PUSCH transmission information corresponding to each TCI state based on the correspondence between PUSCH transmission information and TCI states.

It can be understood that, in the present embodiment, the first relationship is a correspondence relationship between the TCI state and PUSCH transmission information. In this case, the step S202 may be an optional step, that is, whether or not the step S202 is performed, the terminal device may directly obtain PUSCH transmission information corresponding to each TCI state based on the first relationship.

In this embodiment of the present application, the correspondence between PUSCH transmission information and TCI state does not need to be determined based on the second relationship and/or the third relationship, or may also need to be determined by sending a message or signaling or information through a network side, but may be determined by a preconfigured manner, for example, may be determined by content specified by a protocol, and specific protocol content may be divided into the following cases:

Case one:

in the case that the number of slots of PUSCH is equal to 2, the first TCI state included in the first relation corresponds to the first slot, the first slot corresponds to the first PUSCH transmission information, i.e., the first TCI state included in the first relation corresponds to the first PUSCH transmission information; the second TCI state included in the first relation corresponds to a second time slot corresponding to the second PUSCH transmission information, i.e. the second TCI state included in the first relation corresponds to the second PUSCH transmission information.

And a second case:

in the case where the number of slots of the PUSCH is greater than 2 and the PUSCH is configured as a cyclic mapping, the first TCI state included in the first relationship corresponds to the i-th slot, the i-th slot corresponds to the first PUSCH transmission information, i.e., the first TCI state included in the first relationship corresponds to the first PUSCH transmission information; the second TCI state included in the first relation corresponds to the i+1th slot, the i+1th slot corresponds to the second PUSCH transmission information, i.e. the second TCI state included in the first relation corresponds to the second PUSCH transmission information.

Wherein, the above i satisfies: i mod 2 = 1; i+1 is less than or equal to the number of slots in the PUSCH, mod is a modulo operation.

In other words, the first and second slots of the consecutive K slots of the PUSCH correspond to the first and second TCI states, respectively, and the other slots after the first and second slots of the consecutive K slots continue to correspond to the first and second TCI states, respectively.

And a third case:

in the case where the number of slots of PUSCH is greater than 2 and PUSCH is configured to be mapped consecutively, the first TCI state included in the first relation corresponds to the jth slot and the jth+1th slot, the jth slot and the jth+1th slot correspond to the first PUSCH transmission information, i.e., the first TCI state included in the first relation corresponds to the first PUSCH transmission information; the second TCI state included in the first relation corresponds to a j+2th slot and a j+3th slot, the j+2th slot and the j+3th slot corresponding to second PUSCH transmission information, i.e., the second TCI state included in the first relation corresponds to the second PUSCH transmission information.

Wherein, j satisfies the following conditions: j mod 4 = 1; j+3 is less than or equal to the number of slots in the PUSCH, mod is a modulo operation.

In other words, the first and second slots of the consecutive K slots of the PUSCH correspond to the first TCI state, the third and fourth slots of the consecutive K slots correspond to the second TCI state, and the other slots after the first, second, third and fourth slots of the consecutive K slots continue to correspond to the first and second TCI states, respectively, every two slots.

The first relation obtained through the determination in the embodiment of the present application can be used to determine PUSCH transmission information corresponding to each TCI state, so as to perform data transmission, and solve the technical problem that the current PUSCH transmission method for multiple access network devices based on the TCI state is not applicable.

Case four:

the first TCI state included in the first relation corresponds to first PUSCH transmission information, and the second TCI state included in the first relation corresponds to second PUSCH transmission information. The first PUSCH transmission information may be PUSCH transmission information corresponding to a frequency domain resource with a lower frequency domain, and the second PUSCH transmission information may be PUSCH transmission information corresponding to a frequency domain resource with a higher frequency domain; alternatively, the first PUSCH transmission information may be PUSCH transmission information corresponding to a frequency domain resource having a higher frequency domain, and the second PUSCH transmission information may be PUSCH transmission information corresponding to a frequency domain resource having a lower frequency domain.

It should be understood that the first PUSCH transmission information and the second PUSCH transmission information may be PUSCH transmission information corresponding to frequency domain resources of different frequency domains, which is not specifically limited in the embodiment of the present application.

Case five:

the first TCI state included in the first relation corresponds to first PUSCH transmission information, and the second TCI state included in the first relation corresponds to second PUSCH transmission information. The first PUSCH transmission information may be PUSCH transmission information corresponding to a first demodulation reference signal (demodulation reference signal, DMRS) port, and the second PUSCH transmission information may be PUSCH transmission information not corresponding to the first DMRS port; or, the first PUSCH transmission information may be PUSCH transmission information not corresponding to the first DMRS port, and the second PUSCH transmission information may be PUSCH transmission information corresponding to the first DMRS port, which is not specifically limited in the embodiment of the present application.

It should be understood that, corresponding to the first to third cases, the first PUSCH transmission information may be considered as PUSCH transmission information corresponding to the first slot among the K slots, and the second PUSCH transmission information may be considered as PUSCH transmission information corresponding to the second slot among the K slots; alternatively, the first PUSCH transmission information may be regarded as PUSCH transmission information corresponding to a second slot of the K slots, and the second PUSCH transmission information may be regarded as PUSCH transmission information corresponding to a first slot of the K slots, which is not particularly limited in this application.

It should be understood that, corresponding to the fourth case, the first PUSCH transmission information may be regarded as PUSCH transmission information corresponding to a frequency domain resource having a lower frequency domain, and the second PUSCH transmission information may be regarded as PUSCH transmission information corresponding to a frequency domain resource having a higher frequency domain. Or, the first PUSCH transmission information may be PUSCH transmission information corresponding to a frequency domain resource with a higher frequency domain, and the second PUSCH transmission information may be PUSCH transmission information corresponding to a frequency domain resource with a lower frequency domain, which is not specifically limited in the present application.

It should be understood that, corresponding to the fifth case, the first PUSCH transmission information may be regarded as PUSCH transmission information corresponding to the first DMRS port, and the second PUSCH transmission information may be regarded as PUSCH transmission information not corresponding to the first DMRS port; or, the first PUSCH transmission information may be PUSCH transmission information not corresponding to the first DMRS port, the second PUSCH transmission information may be PUSCH transmission information corresponding to the first DMRS port, or the first PUSCH transmission information may be PUSCH transmission information corresponding to a Redundancy Version (RV) indicated by the downlink control information, the second PUSCH transmission information may not be PUSCH transmission information corresponding to a Redundancy Version (RV) indicated by the downlink control information, or the first PUSCH transmission information may be PUSCH transmission information corresponding to the first Redundancy Version (RV), and the second PUSCH transmission information may not be PUSCH transmission information corresponding to the first Redundancy Version (RV), which is not particularly limited in this embodiment of the present application. The DMRS ports are PUSCH-associated DMRS ports; the RV is the RV associated with the PUSCH.

It should be understood that, corresponding to the first to fifth cases, the first PUSCH transmission information may also be regarded as PUSCH transmission information corresponding to the first SRS resource indication field, and the second PUSCH transmission information may also be regarded as PUSCH transmission information corresponding to the second SRS resource indication field; or, the first PUSCH transmission information may be regarded as PUSCH transmission information corresponding to the second SRS resource indication field, and the second PUSCH transmission information may be regarded as PUSCH transmission information corresponding to the first SRS resource indication field, which is not particularly limited in this application.

S203: and the terminal equipment performs data transmission with the network equipment based on the PUSCH transmission information corresponding to the at least one TCI state. Specifically, the terminal device sends uplink data to the network device based on PUSCH transmission information corresponding to at least one TCI state, and the network device receives the uplink data from the terminal device.

After determining the PUSCH transmission information corresponding to the at least one TCI state, the terminal device sends uplink data to the network device based on the PUSCH transmission information corresponding to the at least one TCI state. Correspondingly, the network device receives the uplink data sent by the terminal device.

Specifically, when the PUSCH transmission information corresponding to the at least one TCI state includes information of a transmission opportunity of the PUSCH, the information of the transmission opportunity of the PUSCH may be used for time division transmission; when the PUSCH transmission information corresponding to the at least one TCI state includes information of frequency domain resources of the PUSCH, the information of the frequency domain resources of the PUSCH may be used for frequency division transmission; when the PUSCH transmission information corresponding to the at least one TCI state includes information of a PUSCH layer, the information of the PUSCH layer may be used for space division transmission.

According to the embodiment of the application, data transmission under various transmission scenes such as time division transmission, frequency division transmission, space division transmission and the like can be performed based on the PUSCH transmission information corresponding to at least one TCI state, and the technical problem that the existing TCI state and/or unified TCI state-oriented PUSCH transmission method for a plurality of access network devices is not applicable is solved.

In addition, the application also provides a method for determining the corresponding relation between the SRS resource set and the TCI state.

Specifically, in a protocol specification manner, a corresponding relationship between an SRS resource set and a TCI state is determined, for example, a first SRS resource set corresponds to a first TCI state, and a second SRS resource set corresponds to a second TCI state; or the network device issues at least one message or signaling or information of RRC message, MAC signaling and DCI information to the terminal device. Correspondingly, the terminal equipment receives at least one message or signaling or information from the RRC message, the MAC signaling and the DCI information of the network equipment, and obtains the corresponding relation between the SRS resource set and the TCI state according to the RRC message and/or the MAC signaling and/or the DCI information.

The following description will exemplify a case where the correspondence between the SRS resource set and the TCI state is determined by MAC signaling.

The network device sends the MAC signaling to the terminal device, and correspondingly, the terminal device receives the MAC signaling from the network device. At this time, the correspondence between each SRS resource set and the TCI state may be determined by the bit of the MAC signaling.

For example, in a PUSCH transmission scenario based on a TCI state and oriented to a plurality of access network devices, a correspondence between a first SRS resource set and the TCI state, and/or a correspondence between a second SRS resource set and the TCI state is determined by bits of MAC signaling.

The first SRS resource set corresponds to the first TCI state when the value of the first bit of the MAC signaling is 0, and corresponds to the second TCI state when the value of the first bit of the MAC signaling is 1; and/or, in the case that the value of the second bit of the MAC signaling is 0, the second SRS resource set corresponds to the first TCI state, and in the case that the value of the second bit of the MAC signaling is 1, the second SRS resource set corresponds to the second TCI state.

Through the embodiment of the application, the corresponding relation between each SRS resource set and the TCI state can be determined based on the bit of the MAC signaling, and further the corresponding relation between the PUSCH transmission information and the TCI state is determined, so that the PUSCH transmission oriented to a plurality of access network devices based on the TCI state is supported.

Referring to fig. 3a, it can be obtained from fig. 3a that the corresponding relation between each SRS resource set and the TCI state is determined by using the bit of the MAC signaling, for example, the bit of the MAC signaling used for updating the SRS path loss reference signal.

In detail, referring to fig. 3b, as can be obtained from fig. 3b, the corresponding relationship between each SRS resource set and the TCI state is determined by using bits of the MAC signaling.
