For the Joint mechanism, it can also be understood that one TCI state of network instructions/network configurations/protocol specifications can be applied to part or all of the downlink channels/signals, and part or all of the uplink channels/signals. The Separate mechanism can also be understood as a TCI state of network instructions/network configurations/protocol specifications, which is applicable to some or all downlink channels/signals, or is applicable to some or all uplink channels/signals.

It can be understood that, regardless of whether step S202 is executed, the terminal device can directly perform data transmission based on the obtained PUSCH transmission information corresponding to each TCI state, without limiting the embodiment of the present application to actually executing step S202.

For example, when the first relationship includes the corresponding relationship between TCI status and PUSCH transmission information, in this case, step S202 can be an optional step, that is, whether step S202 is executed or not, the terminal device can directly perform the first relationship based on the first relationship. , obtain the PUSCH transmission information corresponding to each TCI status for data transmission.

The above exemplary situation should not be used to limit the embodiments of the present application. Optional, there are Step S202 is other possible application situations of the optional step, and the embodiment of this application does not exhaustively list them.

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 relationship includes the corresponding relationship between the PUSCH transmission information and the sounding reference signal SRS resource set, and the third relationship includes the corresponding relationship between the SRS resource set and the TCI status.

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

It can be understood that, in the case where the first relationship is determined based on the second relationship and/or the third relationship, or in the case where 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 relationship determined through the embodiments of the present application can be used to determine the PUSCH transmission information corresponding to each TCI state for data transmission, solving the current problem of multiple interfaces based on TCI state and/or unified TCI state. Technical issues related to the inapplicability of the PUSCH transmission method of network access equipment.

Optionally, the above third relationship and/or the second relationship can be determined through RRC messages, and/or MAC signaling, and/or DCI information and other messages or signaling or information issued by the network side, or can be specified by the protocol. The content is determined, and the embodiments of this application do not limit this.

Through the embodiments of the present application, the third relationship and/or the second relationship can be determined based on various methods to determine the first relationship to support PUSCH transmission for multiple access network devices based on TCI status.

method one:

The network device delivers at least one message or signaling among RRC messages, MAC signaling, and DCI information to the terminal device, or information. Correspondingly, the terminal device receives at least one of the RRC message, MAC signaling, and DCI information from the network device, and obtains the above-mentioned first message or signaling or information based on the RRC message and/or MAC signaling and/or DCI information. tertiary relations and/or secondary relations.

Illustratively, the following description takes the case where the third relationship is determined by MAC signaling as an example.

The network device sends MAC signaling to the terminal device, and accordingly, the terminal device receives the MAC signaling from the network device. At this time, the corresponding relationship between each SRS resource set included in the third relationship and the TCI status can be determined by the bits of MAC signaling.

For example, in a PUSCH transmission scenario based on TCI status for multiple access network devices, the correspondence between the first SRS resource set included in the third relationship and the TCI status, and/or the second SRS resource set included in the third relationship The corresponding relationship with the TCI status is determined by the bits of MAC signaling.

When the value of the first bit of the MAC signaling is 0, the first SRS resource set included in the third relationship corresponds to the first TCI state. When the value of the first bit of the MAC signaling is 1, the first SRS resource set included in the third relationship corresponds to the first TCI state. The first SRS resource set included in the third relationship corresponds to the second TCI state; and/or, when the value of the second bit of the MAC signaling is 0, the second SRS resource set included in the third relationship corresponds to the first TCI state. The state corresponds. When the value of the second bit of the MAC signaling is 1, the second SRS resource set included in the third relationship 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 first TCI state. The SRS resource set corresponding to one 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, in 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 understood that the SRS resource set corresponding to the first bit may be the first SRS resource set or the second SRS resource set. It can be understood 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 embodiment of this application are two different bits in MAC signaling.

For example, the first bit may specifically refer to the first bit in the MAC signaling, or may refer to the bit in the MAC signaling used to indicate the corresponding relationship between the first SRS resource set and the TCI state; the second bit may specifically refer to the first bit in the MAC signaling. It may refer to the second bit in the MAC signaling, or it may refer to the bit in the MAC signaling used to indicate the corresponding relationship between the second SRS resource set and the TCI status. This embodiment of the present application does not limit this.

It should be understood that the first TCI state and the second TCI state in the embodiment of the present application are two different TCI states among the above-mentioned at least one TCI state.

For example, the first TCI state may specifically be a TCI state with a smaller ID among the above-mentioned at least one TCI state, or may be the first TCI state among the above-mentioned at least one TCI state; the second TCI state may specifically be the above-mentioned at least one TCI state. The TCI state with a larger ID in one TCI state may also be the second TCI state among the above-mentioned at least one TCI state, and the embodiment of the present application does not limit this.

It can be understood that the first TCI state may also belong to the first TCI state set; the second TCI state may also belong to the second TCI state set. The first TCI status set and the second TCI status set may respectively correspond to different TRPs.

It should be noted that the TRP in this application can be associated with airspace information or slot directions (such as one or a group of beams); or, TRP can be characterized by airspace information or slot directions (such as one or a group of beams); or, TRP It can be characterized by power control parameters. In addition, the TRP in this application can be a functional module (for example, implemented using software functions), or it can be implemented through hardware. This application does not limit the implementation method of the TRP.

It should be understood that the first SRS resource set in the embodiment of the present application may be an SRS resource set with a smaller ID, or may be an SRS resource set with a smaller ID. Therefore, the first SRS resource set and the second SRS resource set may specifically be an SRS resource set with a larger ID, or may be a second SRS resource set, and the embodiments of this application do not limit this.

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

Through the embodiments of the present application, the corresponding relationship between each SRS resource set included in the third relationship and the TCI state can be determined based on the bits of MAC signaling, and then used to determine the first relationship to support multiple interfaces based on the TCI state. PUSCH transmission of network access equipment.

For details, reference may be made to FIG. 3a, which is a schematic diagram of MAC signaling provided by an embodiment of the present application.

It can be seen from Figure 3a that the corresponding relationship between each SRS resource set included in the third relationship and the TCI state is determined using MAC signaling bits, such as the MAC signaling bits used to update the SRS path loss reference signal.

Specifically, the above corresponding relationship may be determined by using the R bits of MAC signaling. For example, if the R bit in the first byte has a value of 0, it means that the SRS resource set is associated with the first TCI state. If the R bit in the first byte has a value of 1, it means that the SRS resource set is associated with the first TCI state. Set associated with the second TCI state. It can be understood that the identifier of the same path loss reference signal can correspond to the identifiers of different SRS resource sets, but each identifier of the SRS resource set will only have one identifier of the path loss reference signal associated with it.

For details, please refer to Figure 3b. From Figure 3b, it can be obtained that the corresponding relationship between each SRS resource set and the TCI state is determined by using the MAC signaling bits.

Specifically, the above corresponding relationship may be determined by using the R bits of MAC signaling. For example, if the first R bit in the second byte has a value of 0, it means that its corresponding SRS resource set (that is, the SRS resource set indicated by the second byte SRS Resource Set ID) is associated with the first TCI status, if the first R bit in the second byte has a value of 1, it indicates that its corresponding SRS resource set (that is, the SRS resource set indicated by the second byte SRS Resource Set ID) is associated Second TCI status. If the value of the first R bit in the third byte is 0, it means that its corresponding SRS resource set (that is, the SRS resource set indicated by the third byte SRS Resource Set ID) is associated with the first TCI status, if the first R bit in the third byte has a value of 1, it means that its corresponding SRS resource set (that is, the SRS resource set indicated by the third byte SRS Resource Set ID) is associated with the second TCI status.

Method two:

The terminal device determines the above third relationship and/or the second relationship through the content specified in the protocol.

For example, the following description takes the case where the third relationship is determined by the content stipulated in the agreement as an example.

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

It should be understood that the first SRS resource set in the embodiment of the present application 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 with a larger ID. The resource set may also be a second SRS resource set, and this embodiment of the present application does not limit this.

Through the embodiments of the present application, the corresponding relationship between each SRS resource set included in the third relationship and the TCI state can be determined based on the protocol content, and then used to determine the first relationship to support TCI state-based access network devices for multiple access network devices. PUSCH transmission.

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

It can be understood that in this embodiment, the first relationship is the corresponding relationship between TCI status and PUSCH transmission information. In this case, the above step S202 can be used as an optional step, that is, regardless of whether step S202 is executed, the terminal device can directly obtain the PUSCH transmission information corresponding to each TCI state based on the first relationship.

In the embodiment of the present application, the corresponding relationship between the PUSCH transmission information and the TCI status does not need to be determined based on the above-mentioned second relationship and/or the third relationship, and it does not need to be determined by the network side issuing messages or signaling or information, but It can be determined through pre-configuration, for example, it can be determined through the content specified in the agreement. The specific agreement content can be divided into the following situations:

Situation one:

In the case where the number of PUSCH slots is equal to 2, the first TCI state included in the first relationship corresponds to the first time slot, and the first time slot corresponds to the first PUSCH transmission information, that is, the first TCI state included in the first relationship corresponds to the first PUSCH transmission information.
