[0056] It can be understood that the system architecture described in the embodiments of the present application is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided in the embodiments of the present application. Those skilled in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0057] Secondly, the relevant concepts involved in the embodiments of the present application are explained.

[0058] 1. Beam

[0059] A beam is a communication resource, which refers to the shape formed on the earth's surface by the electromagnetic waves emitted by the antenna. Different beams can be considered as different resources. The same information or different information can be sent through different beams. Optionally, multiple beams with the same or similar communication characteristics can be regarded as a beam. A beam can include one or more antenna ports for transmitting data channels, control channels, and detection signals. It can be understood that one or more antenna ports forming a beam can also be regarded as an antenna port set.

[0060] The embodiment of the beam in the NR protocol can be a spatial domain filter, or a spatial filter, or a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, quasi-colocation (QCL) information, a QCL assumption, or a QCL indication, etc. Therefore, in the embodiment of the present application, the beam can be replaced by a spatial domain filter, a spatial filter, a spatial parameter, a spatial parameter, a spatial setting, a spatial setting, QCL information, a QCL assumption, a QCL indication, a transmission configuration indication state (Transmission Configuration Indication state, TCI-state), a spatial relationship, etc. The above terms are also equivalent to each other. The beam can also be replaced by other terms representing the beam, which is not limited in the embodiment of the present application. Among them, TCI-state will be introduced later.

[0061] Among them, the beam used to send the signal may refer to the distribution of signal strength formed in different directions in space after the signal is transmitted through the antenna, which is called a transmission beam or a transmit beam (transmission beam, Tx beam), and may also be called a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter or a spatial transmission parameter, a spatial domain transmission setting or a spatial transmission setting.

[0062] The beam used to receive the signal may refer to the signal strength distribution of the wireless signal received from the antenna in different directions in space, which is called a reception beam (Rx beam) and may also be called a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter or a spatial reception parameter, a spatial domain reception setting or a spatial reception setting.

[0063] The beam can be identified by index information. Optionally, the index information may correspond to a resource identifier configured for the UE, for example, the index information may correspond to an identifier or index (ID) or resource of a configured channel status information reference signal (Channel status informationReference Signal, CSI-RS for short), or may correspond to an ID or resource of a configured uplink sounding reference signal. Alternatively, optionally, the index information may also be index information displayed or implicitly carried by a signal or channel carried by the beam, for example, the index information may be index information of the beam indicated by a synchronization signal or a broadcast channel sent by the beam.

[0064] Optionally, the index information of the beam may include but is not limited to the absolute index of the beam, the relative index of the beam, the logical index of the beam, the index of the antenna port corresponding to the beam, the index of the antenna port group corresponding to the beam, the time index of the downlink synchronization signal block, the beam pair connection (beam pair link, BPL) information, the transmit parameter (Txparameter) corresponding to the beam, the receive parameter (Rx parameter) corresponding to the beam, the transmit weight (weight) corresponding to the beam, the weight matrix (weight vector), the weight vector (weight matrix), the receive weight corresponding to the beam, or their indexes, the transmit codebook (codebook) corresponding to the beam, the receive codebook corresponding to the beam, or their indexes.

[0065] 2. TCI-state

[0066] TCI-state is used to indicate to the terminal device: the airspace information used for uplink transmission and / or downlink transmission. Specifically, the network device needs to indicate to the terminal device the airspace information used for transmission, for example, relevant information of the beam, so that the terminal device transmits with the network device according to the airspace information; wherein the network device can send TCI-state to the terminal device so that the terminal device obtains the airspace information for transmission with the network device according to TCI-state.

[0067] TCI-state may include multiple parameters, through which the spatial information, that is, the relevant information of the beam can be determined. For example, TCI-state may include a TCI-state identifier and two QCL information (QCL-info). The TCI-state identifier can be regarded as an index of the TCI-state, which is used to indicate a TCI-state. Each QCL-Info contains a cell field and a partial carrier bandwidth (Bandwidth part, BWP) identifier field, which respectively indicate which BWP of which cell the TCI-state is applied to, that is, different cells or different BWPs of the same cell can be configured with different QCL-Info. QCL-Info also includes a reference signal field, which is used to indicate which reference signal resource the TCI-state forms a QCL relationship with.

[0068] In one implementation, the transmission configuration indication state may be a unified transmission configuration indication state (Unified Transmission Configuration Indication state, Unified TCI-state), or in other words, the TCI-state mode may be a unified TCI-state mode. TCI-state includes a joint transmission configuration indication state (jointTCI-state) and a separate transmission configuration indication state (separate TCI-state, also known as a dedicated transmission configuration indication state), or in other words, the unified TCI-state mode includes a joint TCI-state mode and a separate TCI-state mode.

[0069] The independent TCI-state includes an uplink independent transmission configuration indication state (separate UL TCI-state, also known as an uplink dedicated transmission configuration indication state) and a downlink independent transmission configuration indication state (separate DL TCI-state, also known as a downlink dedicated transmission configuration indication state). The joint TCI-state can indicate the QCL parameters shared by downlink and uplink transmissions; the uplink independent TCI-state is used to indicate the QCL parameters dedicated to uplink transmission, that is, the QCL parameters independently used for uplink transmission; the downlink independent TCI-state is used to indicate the QCL parameters dedicated to downlink transmission, that is, the QCL parameters independently used for downlink transmission.

[0070] For example, if the network device indicates a downlink independent TCI-state for downlink transmission, then the downlink independent TCI-state can be used for the PDSCH / demodulation reference signal (DMRS) and PDCCH / DMRS of the terminal device, as well as some downlink reference signals. If the network device indicates an uplink independent TCI-state for uplink transmission, then the uplink independent TCI-state can be used for the physical uplink shared channel (PUSCH) / DMRS and physical uplink control channel (PUCCH) / DMRS of the terminal device, as well as some uplink reference signals. If the network device indicates a joint TCI-state, then the joint TCI-state can be used for the PDSCH / DMRS and PDCCH / DMRS of the terminal device, as well as some downlink reference signals, and for the PUSCH / DMRS and PUCCH / DMRS of the terminal device, as well as some uplink reference signals.

[0071] It should be noted that there may be other types of TCI-states, and the types of TCI-states are not limited here.

[0072] 3. Activation indication signaling

[0073] Activation indication signaling is used to indicate activation and / or deactivation of at least one TCI-state. Specifically, the network device can configure or indicate a TCI-state pool to the terminal device. For example, the network device sends high-level signaling to the terminal device, and the high-level signaling is used to configure the TCI-state pool, wherein the high-level signaling can be a radio resource control (Radio Resource Control, RRC) signaling. After the network device configures or indicates the TCI-state pool to the terminal device, the network device can send activation indication signaling to the terminal device to indicate activation and / or deactivation of at least one TCI-state through the activation indication signaling. For example, the activation indication signaling indicates activation of TCI-state 1, and correspondingly, also indicates deactivation of TCI-state 2, TCI-state 2 is in an activated state and / or used for transmission before the terminal device receives the activation indication signaling. For another example, the activation indication signaling indicates activation of TCI-state 1. For another example, the activation indication signaling indicates deactivation of TCI-state 2.

[0074] Optionally, in order to reduce the signaling overhead of the activation indication signaling, when the terminal device has multiple service cells, the multiple service cells can be configured as at least one component carrier (CC) list. For multiple service cells belonging to a CC list, an activation indication signaling can be used to activate or update the corresponding transmission configuration indication status.

[0075] Optionally, the serving cell may be configured for single transmission reception point (s-trp) transmission or for multi transmission reception point (m-trp) transmission. For a serving cell of m-trp transmission, TCI-state may be configured based on single downlink control information (s-DCI) or multi-downlink control information (m-DCI).

[0076] 4. Downlink Control Information (DCI)

[0077] The information carried by PDCCH is called DCI. DCI is various information sent by network equipment to schedule terminal equipment, such as resource blocks occupied in the frequency domain, monitoring positions in the time domain, and modulation scheme selection.

[0078] In one implementation, the network device may indicate to the terminal device the spatial domain information used for transmission through DCI. For example, the DCI carries TCI-state, and the terminal device determines the transmission beam information based on the TCI-state carried by the DCI from the network device.

[0079] 5. Subband Full Duplex (SBFD) and non-Subband Full Duplex (non-SBFD)

[0080] Due to the limitation of the uplink and downlink time slot ratio of the time domain duplex (TDD) system, the transmission delay of the time domain duplex system is relatively large. In order to reduce the implementation complexity of the base station, all frequency domain resources of a time division duplex carrier must have the same transmission direction at the same time, that is, the uplink and downlink time slot ratios of different frequency domain resources of a time division duplex carrier cannot be flexibly configured. With the diversification of services, especially considering the business needs of vertical industries, different services have different requirements for uplink and downlink transmission, and a single uplink and downlink time slot ratio cannot meet the needs of different services. Based on the above two points, and considering the complexity of base station implementation, some people have proposed a sub-band full-duplex solution, that is, different subbands (Subband) of the same carrier use different uplink and downlink time slot ratios.

[0081] A carrier component is divided into multiple subbands in the frequency domain on a downlink or flexible symbol. The multiple subbands include an uplink subband (UL Subband) and a downlink subband (DL Subband). The network device can send a downlink signal in the downlink subband and receive an uplink signal in the uplink subband at the same time. That is, a symbol contains both a downlink subband and an uplink subband in the frequency domain, which can be called an SBFD symbol. For the convenience of subsequent description, the time-frequency resources corresponding to the SBFD symbol can be called the time-frequency resources of SBFD. Among them, the time-frequency resources of SBFD include the uplink time-frequency resources of SBFD and the downlink time-frequency resources of SBFD. The uplink time-frequency resources of SBFD refer to the uplink subband part of the SBFD symbol, and the downlink time-frequency resources of SBFD refer to the downlink subband part of the SBFD symbol. Accordingly, a symbol that only contains downlink time-frequency resources or uplink time-frequency resources in the frequency domain can be called a non-SBFD symbol. For the convenience of subsequent description, the time-frequency resources corresponding to non-SBFD can be called non-SBFD time-frequency resources.

[0082] For example, see Figure 2 , Figure 2 This is a schematic diagram of uplink and downlink TDD configuration of time-frequency resources provided in an embodiment of the present application. Figure 2 The D in it represents the time-frequency resources for transmitting downlink signals, and U represents the time-frequency resources for transmitting uplink signals. Among them, time slot (slot) n, time slot n+1, time slot n+2, time slot n+3 are downlink symbols, and time slot n+4 is an uplink symbol. In the frequency domain position of the initial uplink partial carrier bandwidth (Initial UL BWP) corresponding to time slot n+1, time slot n+2, time slot n+3, different subbands can transmit downlink signals and uplink signals respectively. The time-frequency resources corresponding to time slot n+1, time slot n+2, time slot n+3 are called SBFD time-frequency resources; the frequency domain resources corresponding to time slot n are used to transmit downlink signals, and the frequency domain resources corresponding to time slot n+4 are used to transmit uplink signals. The time-frequency resources corresponding to time slot n and time slot n+4 are called non-SBFD time-frequency resources. It should be noted that Figure 2 This is just an example of uplink and downlink TDD configuration of SBFD and non-SBFD time-frequency resources, and does not limit the resource ratio of the two time-frequency resources for transmitting uplink signals and downlink signals. Optionally, time slot n+1, time slot n+2, and time slot n+3 can also be flexible symbols.

[0083] Optionally, the terminal device can obtain the TDD uplink and downlink configuration according to the public uplink and downlink configuration information sent by the network device, or the terminal device can obtain the TDD uplink and downlink configuration according to the public uplink and downlink configuration information and the dedicated uplink and downlink configuration information sent by the network device. In other words, the system provides a variety of slot format configuration methods, where the slot format includes downlink symbols, uplink symbols and flexible symbols. The terminal device can obtain the slot format according to the public uplink and downlink configuration information sent by the network device, or the terminal device can obtain the slot format according to the public uplink and downlink configuration information and the dedicated uplink and downlink configuration information sent by the network device.

[0084] In the communication system, due to the rapid attenuation of high-frequency channels, beam-based transmission and reception are required to ensure coverage. The network device needs to indicate to the terminal device the airspace information used for transmission, so that the terminal device transmits with the network device according to the airspace information. For example, the terminal device determines the transmission beam information of the network device according to the airspace information, and uses the receiving beam information corresponding to the transmission beam information to receive the downlink signal from the network device. In one implementation, the network device can send and indicate to the terminal device to activate the unified transmission configuration indication state, so that the terminal device determines the airspace information for data transmission with the network device according to the unified transmission configuration indication state. At present, the way in which the network device indicates airspace information to the terminal device is not flexible enough. Further research is needed on how the network device indicates airspace information to the terminal device so that the terminal device can effectively transmit data with the network device.

[0085] In view of this, an embodiment of the present application provides a communication processing method and a communication device, which indicates deactivation and / or deactivation of at least one transmission configuration indication state corresponding to at least one time-frequency resource through activation indication signaling, thereby realizing the indication of spatial domain information for different time-frequency resources and improving the flexibility of indicating spatial domain information.

[0086] The following is based on Figure 1 The system architecture shown in the figure introduces the communication processing method provided by the embodiment of the present application in detail. The execution subject in the embodiment of the present application may be a network device and a terminal device. Or the execution subject in the embodiment of the present application may be a device matching the network device, such as a processor, a chip or a chip module, and a device matching the terminal device, such as a processor, a chip or a chip module. The following is an example of a network device and a terminal device.

[0087] See also Figure 3 , Figure 3 : is a flow chart of a communication processing method provided in an embodiment of the present application, which may include but is not limited to the following steps:

[0088] 301, the network device sends an activation instruction signaling to the terminal device. Correspondingly, the terminal device receives the activation instruction signaling from the network device.

[0089] Among them, the activation indication signaling is used to indicate the activation and / or deactivation of at least one TCI-state, at least one TCI-state is the TCI-state corresponding to at least one time-frequency resource, and at least one TCI-state corresponds to at least one time-frequency resource. That is, in the embodiment of the present application, the corresponding TCI-state can be configured for different time-frequency resources, for example, TCI-state 1 is configured for time-frequency resource 1, TCI-state 2 is configured for time-frequency resource 2, and TCI-state 3 is configured for time-frequency resource 3.

[0090] Optionally, at least one TCI-state includes a second TCI-state and a third TCI-state; the second TCI-state is the TCI-state corresponding to the second time-frequency resource, and the third TCI-state is the TCI-state corresponding to the third time-frequency resource. The second time-frequency resource is used to carry the first signal, and the third time-frequency resource is used to carry the first signal and the second signal. The transmission directions of the first signal and the second signal are opposite.

[0091] Optionally, at least one time-frequency resource includes a SBFD time-frequency resource and a non-SBFD time-frequency resource. Optionally, the second time-frequency resource may be a non-SBFD time-frequency resource, and the third time-frequency resource may be a SBFD time-frequency resource. That is, in an embodiment of the present application, the activation indication signaling may be used to indicate the activation and / or deactivation of the TCI-state corresponding to the non-SBFD time-frequency resources and the TCI-state corresponding to the SBFD time-frequency resources. For example, the first signal is an uplink signal, the second signal is a downlink signal, the second time-frequency resource is a non-SBFD time-frequency resource for carrying the uplink signal, and the third time-frequency resource is a SBFD time-frequency resource for carrying the uplink signal and the downlink signal. For another example, the first signal is a downlink signal, the second signal is an uplink signal, the second time-frequency resource is a non-SBFD time-frequency resource for carrying the downlink signal, and the third time-frequency resource is a SBFD time-frequency resource for carrying the downlink signal and the uplink signal.

[0092] 302. The terminal device responds to the activation indication signaling and transmits based on the activated TCI-state.

[0093] Optionally, the terminal device may transmit based on the spatial domain information corresponding to the activated TCI-state. For example, the terminal device may determine the receiving beam information based on the QCL relationship corresponding to the activated TCI-state, and receive the signal or data from the network device according to the receiving beam information.

[0094] Optionally, the activation indication signaling may be a medium access control control element (MAC CE); wherein the activation indication signaling may specifically be at least one of the following two signalings:

[0095] (1) Unified TCI-states Activation / Deactivation MAC CE;

[0096] (2) Newly added activation / deactivation of Media Access Control Control Element (MAC CE).

[0097] For the convenience of subsequent description, the unified transmission configuration indication state activation / deactivation media access control control unit is referred to as the first activation indication signaling, and the newly added activation / deactivation media access control control unit is referred to as the second activation indication signaling.

[0098] Among them, the first activation indication signaling is an activation indication signaling for activating and / or deactivating a unified TCI-state. The second activation indication signaling is an activation indication signaling newly defined relative to the first activation indication signaling. The second activation indication signaling can be used to indicate activation and / or deactivation of a transmission configuration indication state corresponding to a type of time-frequency resource. For example, the second activation indication signaling can be used to indicate activation and / or deactivation of the transmission configuration indication state corresponding to the time-frequency resource of time-frequency resource type 1, or the second activation indication signaling can be used to indicate activation and / or deactivation of the transmission configuration indication state corresponding to the time-frequency resource of time-frequency resource type 2. It should be noted that the activation indication signaling can also be other types of activation indication signaling, which is not limited here.

[0099] In one implementation, when the activation indication signaling is the first activation indication signaling, the mode of each TCI-state in at least one TCI-state is a joint TCI-state mode or an independent TCI-state mode. That is, the TCI-state corresponding to each time-frequency resource in at least one time-frequency resource can be a joint TCI-state or an independent TCI-state. For the description of the joint TCI-state and the independent TCI-state, please refer to the description of the related concepts mentioned above, which will not be repeated here.

[0100] Optionally, at least one TCI-state is the same or different. That is, the TCI-states corresponding to at least one time-frequency resource can be the same or different. In other words, at least one time-frequency resource can share a TCI-state or separately correspond to different TCI-states. For example, at least one time-frequency resource includes time-frequency resource 1, time-frequency resource 2, and time-frequency resource 3. The TCI-state corresponding to time-frequency resource 1 and the TCI-state corresponding to time-frequency resource 2 are the same TCI-state. The TCI-state corresponding to time-frequency resource 1 and the TCI-state corresponding to time-frequency resource 3 are different TCI-states. The TCI-state corresponding to time-frequency resource 2 and the TCI-state corresponding to time-frequency resource 3 are different TCI-states. Another example is that the TCI-state corresponding to time-frequency resource 1 and the TCI-state corresponding to time-frequency resource 2 are the same combined TCI-state. Another example is that the TCI-state corresponding to time-frequency resource 1 and the TCI-state corresponding to time-frequency resource 2 are the same independent TCI-state. Another example is that the TCI-state corresponding to time-frequency resource 1 and the TCI-state corresponding to time-frequency resource 3 are different combined TCI-states. Another example is that the TCI-state corresponding to time-frequency resource 1 and the TCI-state corresponding to time-frequency resource 3 are different independent TCI-states. Another example is that the independent TCI-state corresponding to time-frequency resource 1 and the combined TCI-state corresponding to time-frequency resource 3 are different TCI-states.

[0101] Optionally, the first activation indication signaling can have at least one of the following three configuration methods:

[0102] Method 1: The first activation indication signaling includes the code point Pi field of the TCI-state. Among them, the code point Pi field of the TCI-state is used to indicate that the code point of the i-th TCI-state has multiple TCI-states or a single TCI-state.

[0103] Optionally, the first activation indication signaling can also include a Transmission Configuration Indication state identifier (TCI-state ID) field and a Common / Independent (N / S) field. Among them, the Transmission Configuration Indication state identifier field is used to indicate the TCI-state identifier, and the TCI-state identifier is used to identify the TCI-state. The Common / Independent field is used to indicate that the TCI-state identifier in the same octet as the Common / Independent field is for a combined TCI-state or an independent TCI-state.

[0104] Exemplarily, please refer to Figure 4 , Figure 4It is a structural diagram of a first activation indication signaling provided in an embodiment of the present application. Figure 4 The first activation indication signaling in includes multiple octets such as octet 1 (Oct 1), octet 2 (Oct 2), octet 3 (Oct 3), octet 4 (Oct 4), octet 5 (Oct 5) ... octet N+3 (Oct N+3), and the length of each octet is 8 bits. Among them:

[0105] The Serving Cell ID field is used to indicate the identifier of the serving cell to which the first activation indication signaling is applied.

[0106] The downlink portion carrier bandwidth identifier (DL BWP ID) field is used to indicate the identifier of the downlink portion carrier bandwidth to which the first activation indication signaling is applied.

[0107] The uplink partial carrier bandwidth identifier (UL BWP ID) field is used to indicate the identifier of the uplink partial carrier bandwidth to which the first activation indication signaling is applied.

[0108] The Reserved ("R") field is a reserved bit and is usually set to 0.

[0109] The code point Pi (i=1, ..., 8) field of TCI-state indicates that the code point of the i-th TCI-state has multiple TCI-states or a single TCI-state. For example, at least one time-frequency resource includes non-SBFD time-frequency resources and SBFD time-frequency resources, and the code point Pi field of TCI-state is set to 1, indicating that the code point of the i-th TCI-state includes multiple TCI-states such as an independent TCI-state corresponding to the SBFD time-frequency resources and an independent TCI-state corresponding to the SBFD time-frequency resources. For another example, if the code point Pi field of TCI-state is set to 0, it indicates that the code point of the i-th TCI-state includes one TCI-state, which is used for both non-SBFD time-frequency resources and SBFD time-frequency resources. Here, one TCI-state can be called a common TCI-state; optionally, the common TCI-state can be a joint TCI-state.

[0110] The transmission configuration indication state flag field is used to indicate the transmission configuration indication state flag. Figure 4 , transmission configuration indication state identifier 1, transmission configuration indication state identifier 2, ..., transmission configuration indication state identifier N are shown, where N is an integer greater than or equal to 1.

[0111] The common / independent field is used to indicate whether the transmission configuration indication state identifier in the same octet as the common / independent field is used for a common TCI-state or an independent TCI-state. Wherein, if the common / independent field is set to 1, the transmission configuration indication state identifier in the same octet as the common / independent field is used to identify the common TCI-state. If the common / independent field is set to 0, the transmission configuration indication state identifier in the same octet as the common / independent field is used to identify an independent TCI-state, for example, to identify an independent TCI-state corresponding to the time-frequency resources of SBFD.

[0112] Optionally, the code point Pi field of the TCI-state indicates that the code point of the i-th TCI-state has multiple different TCI-states, then the TCI-state identifiers corresponding to the multiple different TCI-states are arranged in sequence in the TCI-state identifier fields in multiple octets. Optionally, the code point of the TCI-state mapped to the TCI-state is determined according to the sequential position of the transmission configuration indication state identifier field corresponding to the TCI-state in all the transmission configuration indication state identifier fields. For example, the code point field P of the TCI-state 1 Indication: The code point of the first TCI-state includes two TCI-states, namely, independent TCI-state 1 corresponding to the SBFD time-frequency resources and independent TCI-state 2 corresponding to the non-SBFD time-frequency resources; independent TCI-state 1 is identified by transmission configuration indication state identifier 1, and independent TCI-state 2 is identified by transmission configuration indication state identifier 2. The code point field P of the TCI-state to which independent TCI-state 1 and independent TCI-state 2 are mapped 1 , and the field where the transmission configuration indication state identifier 1 is located and the field where the transmission configuration indication state identifier 2 is located are arranged in octet 4 and octet 5 in sequence. For example, the code point field P of TCI-state 2 The code point indicating the second TCI-state includes the joint TCI-state 3 of the time-frequency resources of SBFD, the joint TCI-state 3 is identified by the transmission configuration indication state identifier 3, and the code point field P of the TCI-state to which the joint TCI-state 3 is mapped 2 and the associated TCI-state 3 record in octet 6 ( Figure 4 (not shown).

[0113] Optionally, Figure 4 The first activation indication signaling shown is applicable to a scenario of single sending and receiving point transmission.

[0114] Mode 2: The first activation indication signaling includes a first field, wherein the first field is used to indicate whether the joint TCI-state identified by the TCI-state identifier corresponding to the TCI-state code point is applicable to at least one time-frequency resource.

[0115] For example, see Figure 5 , Figure 5 This is a structural diagram of another first activation indication signaling provided in an embodiment of the present application. Figure 5 Medium F i,j Indicates the first field, used to indicate whether the joint TCI-state identified by the transmission configuration indication state identifier corresponding to TCI-state code point i is applicable to time-frequency resource j. i,j =0 indicates that TCI-state code point i is not applied to the transmission configuration indication state identifier of time-frequency resource j, that is, the joint TCI-state identified by the transmission configuration indication state identifier corresponding to TCI-state code point i is applicable to time-frequency resource j, for example, the joint TCI-state identified by the transmission configuration indication state identifier corresponding to TCI-state code point i is applicable to the uplink signal and the downlink signal of time-frequency resource j. i,j =1 means that the transmission configuration indication state identifier corresponding to TCI-state code point i is applied to time-frequency resource j, that is, the independent TCI-state identified by the transmission configuration indication state identifier corresponding to TCI-state code point i is applied to time-frequency resource j, for example, the independent TCI-state identified by the transmission configuration indication state identifier corresponding to TCI-state code point i is applied to the uplink signal and downlink signal carried by time-frequency resource j.

[0116] Optionally, for at least one time-frequency resource including a SBFD time-frequency resource and a non-SBFD time-frequency resource, F i,1 =0 indicates that the TCI-state identifier of TCI-state code point i is not applied to non-SBFD time-frequency resources, and the joint TCI-state identified by the transmission configuration indication state identifier of TCI-state code point i is applicable to non-SBFD time-frequency resources. i,1 =1 indicates that the TCI-state identifier corresponding to TCI-state code point i is applied to non-SBFD time-frequency resources, that is, the independent TCI-state identified by the transmission configuration indication state identifier corresponding to TCI-state code point i is applied to non-SBFD time-frequency resources. i,2 =0 indicates that the transmission configuration indication state identifier of the TCI-state code point i is not applied to the time-frequency resources of SBFD, and the joint TCI-state identified by the transmission configuration indication state identifier corresponding to the TCI-state code point i is applied to the time-frequency resources of SBFD. i,2=1 indicates that the TCI-state identifier corresponding to TCI-state code point i is applied to the time-frequency resources of SBFD, that is, the independent TCI-state identified by the transmission configuration indication state identifier corresponding to TCI-state code point i is applied to the time-frequency resources of SBFD. Figure 5 In it, i∈[1,2,3,4,5,6,7,8], j∈[1,2].

[0117] Figure 5 For descriptions of the serving cell identification field, downlink partial carrier bandwidth identification field, reserved field, and transmission configuration indication status identification field shown in Figure 4 The description of the corresponding fields in is not repeated here.

[0118] Mode 3: The first activation indication signaling includes a third field. The third field is used to indicate whether the TCI-state code point includes an uplink TCI-state and / or a downlink TCI-state of at least one time-frequency resource. Optionally, the third field may be multiple, and the time-frequency resources corresponding to each third field are the same or different.

[0119] For example, see Figure 6 , Figure 6 This is a structural diagram of another first activation indication signaling provided in an embodiment of the present application. Figure 6 The third field includes G i,j and S i,j Among them, G i,j Used to indicate whether TCI-state code point i contains the uplink TCI-state and / or downlink TCI-state of time-frequency resource 1. i,j Used to indicate whether TCI-state code point i includes the uplink TCI-state and / or downlink TCI-state of time-frequency resource 2.

[0120] For example, G i,1 Set to 0, indicating that TCI-state code point i does not include the downlink TCI-state of time-frequency resource 1. i,1 Set to 1, indicating that TCI-state codepoint i includes the downlink TCI-state of time-frequency resource 1. i,2 Set to 0, indicating that TCI-state code point i does not include the uplink TCI-state of time-frequency resource 1. i,2 Set to 1, indicating that TCI-state code point i includes the uplink TCI-state of time-frequency resource 1.

[0121] For example, S i,1 Set to 0, indicating that TCI-state code point i does not include the downlink TCI-state of time-frequency resource 2.i,1 Set to 1, indicating that TCI-state code point i includes the downlink TCI-state of time-frequency resource 2. i,2 Set to 0, indicating that TCI-state code point i does not include the uplink TCI-state of time-frequency resource 2. i,2 Set to 1, indicating that TCI-state code point i includes the uplink TCI-state of time-frequency resource 2.

[0122] Optionally, the time-frequency resource 1 may be a non-SBFD time-frequency resource, and the time-frequency resource 2 may be a SBFD time-frequency resource.

[0123] Figure 6 For descriptions of the serving cell identification field, downlink portion carrier bandwidth identification field, uplink portion carrier bandwidth identification field, reserved field, and transmission configuration indication status identification field, see Figure 4 The description of the corresponding fields in is not repeated here.

[0124] It should be noted that the above three configuration methods of the first activation indication signaling are merely examples and do not constitute a limitation of the first activation indication signaling in the embodiments of the present application. The first activation indication signaling may also adopt other configuration methods.

[0125] In another implementation, when the activation indication signaling is the second activation indication signaling, the activation indication signaling includes type indication information; the type indication information indicates the activation type, the activation type is the time-frequency resource type that carries the activated TCI-state, and the activation indication signaling indicates that the activated TCI-state includes the activated TCI-state. After receiving the activation indication signaling, the terminal device can determine the activation type according to the type indication information in the activation indication signaling.

[0126] Optionally, the time-frequency resource type includes SBFD and non-SBFD. The type indication information indicates that the activation type is SBFD, and the second activation indication signaling indicates that the activated TCI-state includes the TCI-state of the time-frequency resources of SBFD. The type indication information indicates that the activation type is non-SBFD, and the second activation indication signaling indicates that the activated TCI-state includes the TCI-state of the time-frequency resources of non-SBFD.

[0127] For example, see Figure 7 , Figure 7 It is a structural diagram of a second activation indication signaling provided in an embodiment of the present application. Figure 7The symbol type field records type indication information. The type indication information is used to indicate whether the second activation indication signaling indicates activation of the TCI-state of the non-SBFD time-frequency resources or the TCI-state of the SBFD time-frequency resources.

[0128] Figure 7 The downlink / uplink (D / U) field is used to indicate whether the transmission configuration indication state identifier in the same octet as the uplink / downlink field is the TCI-state for joint / downlink or the TCI-state for uplink. The control resource pool identifier field is used to indicate the identifier of the control resource pool, which is used to identify the control resource pool. Figure 7 The meaning and configuration of other fields in can be found in Figure 4 The description is not repeated here.

[0129] In one implementation, before executing step 301, the network device configures or indicates the TCI-state to the terminal device, which can be implemented in at least one of the following two ways:

[0130] The first way: before sending the activation indication signaling, the network device sends downlink control information to the terminal device. Accordingly, before receiving the activation indication signaling, the terminal device receives the downlink control information from the network device.

[0131] Among them, the downlink control information includes at least one field, at least one field is used to indicate at least one TCI-state set corresponding to at least one time-frequency resource, at least one field corresponds one-to-one to the at least one time-frequency resource, and at least one time-frequency resource corresponds one-to-one to at least one TCI-state set.

[0132] Optionally, at least one TCI-state activated and / or deactivated by the activation indication signaling may correspond one-to-one to at least one TCI-state set. That is, the terminal device responds to the activation indication signaling, and the activated TCI-state used for transmission may belong to at least one TCI-state set.

[0133] Optionally, in the case where at least one time-frequency resource includes a SBFD time-frequency resource and a non-SBFD time-frequency resource, at least one field includes a first TCI-state field and a second TCI-state field, the first TCI-state field is used to indicate the transmission configuration indication state corresponding to the non-SBFD time-frequency resource, and the second TCI-state field is used to indicate the TCI-state corresponding to the SBFD time-frequency resource. For example, the first TCI-state field may include 3 bits, specifically representing 8 different values ​​(codepoint, also known as codepoint), each value corresponding to an index or identifier of a TCI-state, and the index or identifier can identify a TCI-state corresponding to a non-SBFD time-frequency resource. For another example, the second TCI-state field may include 3 bits, specifically representing 8 different values, each value corresponding to an index or identifier of a TCI-state, and the index or identifier can identify a TCI-state corresponding to a SBFD time-frequency resource. Optionally, the second TCI-state field may be a TCI-state field newly added relative to the first TCI-state field.

[0134] For the description of at least one field in the downlink control information, reference may be made to the aforementioned description of related concepts and will not be repeated here.

[0135] The second way: before sending the activation indication signaling, the network device sends the second higher layer signaling to the terminal device. Accordingly, before receiving the activation indication signaling, the terminal device receives the second higher layer signaling from the network device.

[0136] Among them, the second high-level signaling is used to configure the TCI-state set corresponding to the first time-frequency resource, and at least one time-frequency resource includes the first time-frequency resource. Optionally, the network device can configure the corresponding TCI-state set for some or all of the time-frequency resources in at least one time-frequency resource, and carry the configured TCI-state set in the second high-level signaling to send it to the terminal device. The activation indication signaling indicates that at least one TCI-state activated and / or deactivated may belong to the TCI-state set configured by the second high-level signaling.

[0137] For example, the first time-frequency resource may be a time-frequency resource of SBFD, and the second high-level signaling may be used to configure the TCI-state set corresponding to the time-frequency resource of SBFD. For another example, the first time-frequency resource may be a time-frequency resource of non-SBFD, and the second high-level signaling may be used to configure the TCI-state set corresponding to the time-frequency resource of non-SBFD. For another example, the first time-frequency resource may include the time-frequency resource of SBFD and the time-frequency resource of non-SBFD, and the second high-level signaling may be used to configure the TCI-state set corresponding to the time-frequency resource of SBFD and the TCI-state set corresponding to the time-frequency resource of non-SBFD.

[0138] Optionally, the second higher layer signaling may be RRC signaling.

[0139] exist Figure 3 In the illustrated embodiment, the network device sends an activation indication signaling to the terminal device, and through the activation indication signaling indicates activation and / or deactivation of at least one transmission configuration indication state corresponding to at least one time-frequency resource, thereby realizing indication of spatial domain information for different time-frequency resources, thereby improving the flexibility of indicating spatial domain information.

[0140] See also Figure 8 , Figure 8 : is a flow chart of another communication processing method provided in an embodiment of the present application, which may include but is not limited to the following steps:

[0141] 801, the network device sends a first high-layer signaling to the terminal device. Correspondingly, the terminal device receives the first high-layer signaling from the network device.

[0142] 802, the network device sends an activation indication signaling to the terminal device. Correspondingly, the terminal device receives the activation indication signaling from the network device.

[0143] 803. The terminal device responds to the activation indication signaling and transmits based on the activated TCI-state.

[0144] Among them, the activation indication signaling is used to indicate the activation and / or deactivation of at least one TCI-state, at least one TCI-state is a TCI-state corresponding to at least one time-frequency resource, and at least one TCI-state has a one-to-one correspondence with at least one time-frequency resource. The first high-level signaling is used to configure the associated TCI-state of the first TCI-state, and at least one TCI-state includes the first TCI-state. Optionally, the first high-level signaling can be RRC signaling.

[0145] Optionally, the first TCI-state is included in a first TCI-state set, and the network device configures an associated TCI-state for each TCI-state in the first TCI-state set. The first high-layer signaling may be used to configure an associated TCI-state for each TCI-state in the first TCI-state set.

[0146] Optionally, the first TCI-state is the TCI-state corresponding to the time-frequency resources of SBFD, and the associated TCI-state of the first TCI-state is the TCI-state corresponding to the time-frequency resources of non-SBFD; or, the first TCI-state is the TCI-state corresponding to the time-frequency resources of non-SBFD, and the associated TCI-state of the first TCI-state is the TCI-state corresponding to the time-frequency resources of SBFD.

[0147] The activated TCI-state includes the first TCI-state and the associated TCI-state of the first TCI-state. The terminal device determines that the TCI-state to be activated by the activation indication signaling is the first TCI-state, and determines that the first TCI-state has an associated TCI-state according to the first high-layer signaling, so that the activated TCI-state includes the first transmission configuration indication and the associated TCI-state of the first TCI-state.

[0148] For example, in the s-trp scenario, the TCI-state code point value in the activation indication signaling is 0, and the code point maps TCI-state 1. The first high-level signaling configures TCI-state 1 to associate TCI state 2, so that the terminal device determines that the activated TCI-state includes TCI-state 1 and TCI-state 2. In addition, the TCI-state code point value in the activation indication signaling is 1, and the code point maps TCI-state 4. TCI-state 4 can be a TCI-state shared by multiple time-frequency resources. For example, TCI-state 4 can be a TCI-state shared by SBFD time-frequency resources and non-SBFD time-frequency resources, so that the terminal device determines that the activated TCI-state includes TCI-state 4 shared by multiple time-frequency resources.

[0149] For example, in the scenario of m-trp of s-DCI, the TCI-state code point in the activation indication signaling takes the value of 0, which can map TCI-state 1. The first high-level signaling configures TCI-state 1 to associate with TCI-state 4, so that the terminal device determines that the activated TCI-state includes TCI-state 1 and TCI-state 4; wherein, TCI-state 1 can be a shared TCI-state corresponding to the SBFD time-frequency resources of trp1 and trp2, and TCI-state 4 can be a shared TCI-state for the non-SBFD time-frequency resources of trp1 and trp2. In addition, for another example, the TCI-state code point value in the activation indication signaling is 1, and the code point can be mapped to TCI-state 1 and TCI-state 4, so that the terminal device determines that the activated TCI-state includes TCI-state 1 and TCI-state 4; wherein TCI-state 1 can be a common TCI-state corresponding to the SBFD and non-SBFD time-frequency resources of trp1, and TCI-state 4 can be a common TCI-state corresponding to the SBFD and non-SBFD time-frequency resources of trp2.
