[0058] It can be understood that the system architecture described in the embodiment of the present application is for the purpose of more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided by the embodiment of the present application. Those skilled in the art will know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0059] Secondly, the relevant concepts involved in the embodiments of this application are explained.

[0060] 1. Beam

[0061] A beam is a communication resource, referring to the shape formed on the Earth's surface by electromagnetic waves emitted by an antenna. Different beams can be considered different resources. Different beams can transmit the same or different information. Alternatively, multiple beams with the same or similar communication characteristics can be considered a single beam. A beam can include one or more antenna ports for transmitting data channels, control channels, and sounding signals. It should be understood that the one or more antenna ports that form a beam can also be considered an antenna port set.

[0062] 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 (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.

[0063] Among them, the beam used to send the signal can 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 can 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.

[0064] The beam used to receive signals may refer to the signal strength distribution of wireless signals received from an antenna in different directions in space, which is called a reception beam (Rx beam). It 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.

[0065] 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 (CSI-RS), or may correspond to an ID or resource of a configured uplink sounding reference signal. Alternatively, 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 broadcast channel sent via the beam.

[0066] 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 link (BPL) information, the transmit parameter (Tx parameter) 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.

[0067] 2. TCI-state

[0068] The TCI-state is used to indicate to the terminal device the spatial information used for uplink and / or downlink transmission. Specifically, the network device needs to indicate to the terminal device the spatial information used for transmission, such as beam-related information, so that the terminal device can transmit with the network device based on the spatial information. The network device can send the TCI-state to the terminal device so that the terminal device can obtain the spatial information for transmission with the network device based on the TCI-state.

[0069] TCI-state can include multiple parameters, through which spatial information, that is, relevant information of the beam can be determined. For example, TCI-state can 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, used to indicate a TCI-state, and 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.

[0070] In one implementation, the transmission configuration indication state may be a unified transmission configuration indication state (Unified TCI-state). Alternatively, the TCI-state mode may be a unified TCI-state mode. TCI-state includes a joint TCI-state and a separate TCI-state (also known as a dedicated TCI-state). Alternatively, the unified TCI-state mode includes a joint TCI-state mode and a separate TCI-state mode.

[0071] The independent TCI-state includes the separate UL TCI-state (also known as the uplink dedicated transmission configuration indication state) and the separate DL TCI-state (also known as the downlink dedicated transmission configuration indication state). The combined 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; and 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.

[0072] 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.

[0073] It should be noted that there may be other types of TCI-states, and the types of TCI-states are not limited here.

[0074] 3. Activation indication signaling

[0075] Activation indication signaling is used to indicate the activation and / or deactivation of at least one TCI-state. Specifically, the network device may configure or indicate a TCI-state pool to the terminal device. For example, the network device sends high-layer signaling to the terminal device, and the high-layer signaling is used to configure the TCI-state pool, wherein the high-layer signaling may be a Radio Resource Control (RRC) signaling. After the network device configures or indicates the TCI-state pool to the terminal device, the network device may send activation indication signaling to the terminal device to indicate the activation and / or deactivation of at least one TCI-state through the activation indication signaling. For example, the activation indication signaling indicates the activation of TCI-state 1, and correspondingly, also indicates the deactivation of TCI-state 2, and 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 the activation of TCI-state 1. For another example, the activation indication signaling indicates the deactivation of TCI-state 2.

[0076] Optionally, in order to reduce the signaling overhead of 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, one activation indication signaling can be used to activate or update the corresponding transmission configuration indication status.

[0077] Optionally, the serving cell can be configured for single transmission reception point (s-trp) transmission or multi transmission reception point (m-trp) transmission. For a serving cell with m-trp transmission, TCI-state can be configured based on single downlink control information (s-DCI) or multi-downlink control information (m-DCI).

[0078] 4. Downlink Control Information (DCI)

[0079] The information carried by the PDCCH is called DCI. DCI is a variety of information sent by network equipment to schedule terminal devices, such as resource blocks occupied in the frequency domain, monitoring locations in the time domain, and modulation scheme selection.

[0080] 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 sending beam information based on the TCI-state carried by the DCI from the network device.

[0081] 5. Subband Full Duplex (SBFD) and non-Subband Full Duplex (non-SBFD)

[0082] Due to the limitations of the uplink and downlink time slot ratios 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, either uplink or downlink. 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. A single uplink and downlink time slot ratio cannot meet the needs of different services. Based on the above two points, and taking into account 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.

[0083] A carrier component is divided into multiple subbands in the frequency domain on a downlink or flexible symbol. These subbands include uplink subbands (UL subbands) and downlink subbands (DL subbands). Network devices can transmit downlink signals on downlink subbands and simultaneously receive uplink signals on uplink subbands. This means that a symbol containing both downlink and uplink subbands in the frequency domain is referred to as an SBFD symbol. For ease of description, the time-frequency resources corresponding to an SBFD symbol are referred to as SBFD time-frequency resources. SBFD time-frequency resources include uplink and downlink time-frequency resources. The uplink time-frequency resources of an SBFD symbol are the uplink subband portion of the SBFD symbol, while the downlink time-frequency resources of an SBFD symbol are the downlink subband portion of the SBFD symbol. Accordingly, a symbol containing only downlink or uplink time-frequency resources in the frequency domain is referred to as a non-SBFD symbol. For ease of description, the time-frequency resources corresponding to non-SBFD symbols are referred to as non-SBFD time-frequency resources.

[0084] For example, please refer to Figure 2, which is a schematic diagram of the uplink and downlink TDD configuration of a time-frequency resource provided in an embodiment of the present application. D in Figure 2 represents the time-frequency resource for transmitting downlink signals, and U represents the time-frequency resource 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, and 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, and 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 only illustrates the uplink and downlink TDD configurations for SBFD and non-SBFD time-frequency resources and does not limit the resource allocation ratio for transmitting uplink and downlink signals using the two time-frequency resources. Optionally, time slots n+1, n+2, and n+3 can also be flexible symbols.

[0085] Optionally, the terminal device can obtain the TDD uplink and downlink configuration based on the public uplink and downlink configuration information sent by the network device, or the terminal device can obtain the TDD uplink and downlink configuration based on 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 multiple slot format configuration methods, where the slot format includes downlink symbols, uplink symbols, and flexible symbols. The terminal device can obtain the slot format based on the public uplink and downlink configuration information sent by the network device, or the terminal device can obtain the slot format based on the public uplink and downlink configuration information and the dedicated uplink and downlink configuration information sent by the network device.

[0086] In a 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 spatial information used for transmission, so that the terminal device can transmit with the network device according to the spatial information. For example, the terminal device determines the transmission beam information of the network device based on the spatial information, and uses the reception beam information corresponding to the transmission beam information to receive the downlink signal from the network device. In one implementation, the network device can activate the unified transmission configuration indication state by sending and indicating to the terminal device, so that the terminal device determines the spatial information for data transmission with the network device according to the unified transmission configuration indication state. Currently, the way in which the network device indicates spatial information to the terminal device is not flexible enough. Further research is needed on how the network device indicates spatial information to the terminal device so that the terminal device can effectively transmit data with the network device.

[0087] 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.

[0088] The following is a detailed description of the communication processing method provided in an embodiment of the present application based on the system architecture shown in Figure 1. The execution subjects in the embodiments of the present application can be network devices and terminal devices. Alternatively, the execution subjects in the embodiments of the present application can be devices that match the network devices, such as processors, chips, or chip modules, and devices that match the terminal devices, such as processors, chips, or chip modules. The following description takes network devices and terminal devices as examples.

[0089] Please refer to FIG3 , which is a flowchart of a communication processing method provided by an embodiment of the present application. The method may include but is not limited to the following steps:

[0090] 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.

[0091] Among them, the activation indication signaling is used to indicate the activation and / or deactivation of at least one TCI-state, and the at least one TCI-state is the TCI-state corresponding to at least one time-frequency resource, and the at least one TCI-state has a one-to-one correspondence with at least one time-frequency resource. That is, in an embodiment of the present application, corresponding TCI-states 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.

[0092] 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.

[0093] Optionally, at least one time-frequency resource includes an 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 an SBFD time-frequency resource. That is, in an embodiment of the present application, activation indication signaling may be used to indicate activation and / or deactivation of the TCI-state corresponding to the non-SBFD time-frequency resource and the TCI-state corresponding to the SBFD time-frequency resource. 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 an SBFD time-frequency resource for carrying both 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 an SBFD time-frequency resource for carrying both the downlink signal and the uplink signal.

[0094] 302. The terminal device responds to the activation indication signaling and transmits based on the activated TCI-state.

[0095] 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 receive beam information based on the QCL relationship corresponding to the activated TCI-state, and receive signals or data from the network device based on the receive beam information.

[0096] 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:

[0097] (1) Unified TCI-states Activation / Deactivation MAC CE;

[0098] (2) Newly added activation / deactivation Media Access Control Control Element (MAC CE).

[0099] 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.

[0100] 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 the 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 the 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 the 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.

[0101] 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 a description of the joint TCI-state and independent TCI-state, please refer to the aforementioned explanation of the related concepts and will not be repeated here.

[0102] Optionally, at least one TCI-state is the same or different. That is, the TCI-state corresponding to at least one time-frequency resource may be the same or different. In other words, at least one time-frequency resource may share a TCI-state, or correspond to different TCI-states separately. 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, and the TCI-state corresponding to time-frequency resource 2 and the TCI-state corresponding to time-frequency resource 3 are different TCI-states. For another example, the TCI-state corresponding to time-frequency resource 1 and the TCI-state corresponding to time-frequency resource 2 are the same joint TCI-state. For another example, 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. For another example, the TCI-state corresponding to time-frequency resource 1 and the TCI-state corresponding to time-frequency resource 3 are different joint TCI-states. For another example, the TCI-state corresponding to time-frequency resource 1 and the TCI-state corresponding to time-frequency resource 3 are different independent TCI-states. For another example, the independent TCI-state corresponding to time-frequency resource 1 and the joint TCI-state corresponding to time-frequency resource 3 are different TCI-states.

[0103] Optionally, the first activation indication signaling may be configured in at least one of the following three ways:

[0104] In mode 1, the first activation indication signaling includes a TCI-state code point Pi field, where the TCI-state code point Pi field is used to indicate whether the i-th TCI-state code point has multiple TCI-states or a single TCI-state.

[0105] Optionally, the first activation indication signaling may further include a transmission configuration indication state identifier (TCI-state ID) field and a common / independent (N / S) field. The transmission configuration indication state identifier field is used to indicate the TCI-state identifier, which is used to identify the TCI-state; and the common / independent field is used to indicate whether the TCI-state identifier in the same octet as the common / independent field is used for a common TCI-state or an independent TCI-state.

[0106] For example, please refer to Figure 4, which is a schematic diagram of the structure of a first activation indication signaling provided in an embodiment of the present application. The first activation indication signaling in Figure 4 includes multiple octets, including 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), each octet being 8 bits long. Wherein:

[0107] The Serving Cell ID field is used to indicate the identifier of the serving cell to which the first activation indication signaling is applied.

[0108] 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.

[0109] The uplink portion carrier bandwidth identifier (UL BWP ID) field is used to indicate the identifier of the uplink portion carrier bandwidth applied by the first activation indication signaling.

[0110] The Reserved ("R") field is a reserved bit and is usually set to 0.

[0111] The code point Pi (i=1, ..., 8) field of the 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 the 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 the 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. The one TCI-state here can be called a common TCI-state; optionally, the common TCI-state can be a joint TCI-state.

[0112] The transmission configuration indication state flag field is used to indicate the transmission configuration indication state flag. FIG4 shows transmission configuration indication state flag 1, transmission configuration indication state flag 2, ..., transmission configuration indication state flag N, where N is an integer greater than or equal to 1.

[0113] 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 for a common TCI-state or an independent TCI-state. 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, an independent TCI-state corresponding to the time-frequency resources of SBFD.

[0114] Optionally, the TCI-state codepoint Pi field indicates that the codepoint of the i-th TCI-state has multiple different TCI-states. In this case, the TCI-state identifiers corresponding to the multiple different TCI-states are arranged sequentially in the TCI-state identifier fields in multiple octets. Optionally, the TCI-state codepoint to which the TCI-state is mapped is determined based on the sequential position of the transmission configuration indication state identifier field corresponding to the TCI-state among all transmission configuration indication state identifier fields. For example, the code point field P1 of TCI-state indicates: 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, independent TCI-state 2 is identified by transmission configuration indication state identifier 2, independent TCI-state 1 and independent TCI-state 2 are mapped to the code point field P1 of TCI-state, 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, respectively. For example, the code point field P2 of TCI-state indicates that the code point of 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, the joint TCI-state 3 is mapped to the code point field P2 of TCI-state, and the joint TCI-state 3 is recorded in octet 6 (not shown in Figure 4).

[0115] Optionally, the first activation indication signaling shown in FIG4 is applicable to a scenario of single sending and receiving point transmission.

[0116] 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 codepoint is applicable to at least one time-frequency resource.

[0117] For example, please refer to FIG5, which is a structural diagram of another first activation indication signaling provided by an embodiment of the present application. 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 both the uplink signal and the downlink signal of time-frequency resource j. i,j =1 indicates 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.

[0118] Optionally, for at least one time-frequency resource including an 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 means that TCI-state code point i is not applied to the transmission configuration indication state identifier of the SBFD time-frequency resources, and the joint TCI-state identified by the transmission configuration indication state identifier corresponding to TCI-state code point i is applied to the SBFD time-frequency resources. i,2= 1 indicates that the TCI-state identifier corresponding to TCI-state codepoint 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 codepoint i is applied to the time-frequency resources of SBFD. In Figure 5, i∈[1, 2, 3, 4, 5, 6, 7, 8] and j∈[1, 2].

[0119] For the description of the serving cell identification field, downlink portion carrier bandwidth identification field, reserved field, and transmission configuration indication status identification field shown in FIG5 , please refer to the description of the corresponding fields in FIG4 and will not be repeated here.

[0120] Mode 3: The first activation indication signaling includes a third field. The third field is used to indicate whether the TCI-state codepoint includes the uplink TCI-state and / or downlink TCI-state of at least one time-frequency resource. Optionally, there may be multiple third fields, and each third field may correspond to the same or different time-frequency resources.

[0121] For example, please refer to FIG6, which is a structural diagram of another first activation indication signaling provided by an embodiment of the present application. The third field in FIG6 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.

[0122] 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 codepoint i includes the uplink TCI-state of time-frequency resource 1.

[0123] 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,2Set 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 codepoint i includes the uplink TCI-state of time-frequency resource 2.

[0124] 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.

[0125] For the description of the service cell identification field, downlink carrier bandwidth identification field, uplink carrier bandwidth identification field, reserved field, and transmission configuration indication status identification field shown in Figure 6, please refer to the description of the corresponding fields in Figure 4 and will not be repeated here.

[0126] 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.

[0127] 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 an activation type, the activation type is a time-frequency resource type that carries an activated TCI-state, and the TCI-state indicated by the activation indication signaling as activated includes an activated TCI-state. After receiving the activation indication signaling, the terminal device may determine the activation type based on the type indication information in the activation indication signaling.

[0128] 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.

[0129] For example, refer to FIG. 7 , which is a schematic diagram of the structure of a second activation indication signaling provided in an embodiment of the present application. The Symbol Type field in FIG. 7 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 non-SBFD time-frequency resources or the TCI-state of SBFD time-frequency resources.

[0130] In 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 for the joint / downlink TCI-state or the uplink TCI-state. 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. The meaning and configuration of the other fields in Figure 7 can be found in the description of Figure 4 and are not repeated here.

[0131] 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:

[0132] The first way: before sending the activation indication signaling, the network device sends downlink control information to the terminal device. Correspondingly, before receiving the activation indication signaling, the terminal device receives downlink control information from the network device.

[0133] 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 with the at least one time-frequency resource, and at least one time-frequency resource corresponds one-to-one with at least one TCI-state set.

[0134] Optionally, the 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.

[0135] Optionally, in the case where at least one time-frequency resource includes an 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.

[0136] For the description of at least one field in the downlink control information, reference may be made to the aforementioned description of related concepts, which will not be elaborated here.

[0137] 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.

[0138] The second high-layer 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-layer signaling 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-layer signaling.

[0139] For example, the first time-frequency resource may be a time-frequency resource for SBFD, and the second high-layer signaling may be used to configure the TCI-state set corresponding to the time-frequency resource for SBFD. For another example, the first time-frequency resource may be a time-frequency resource for non-SBFD, and the second high-layer signaling may be used to configure the TCI-state set corresponding to the time-frequency resource for non-SBFD. For another example, the first time-frequency resource may include time-frequency resources for SBFD and time-frequency resources for non-SBFD, and the second high-layer signaling may be used to configure the TCI-state set corresponding to the time-frequency resource for SBFD and the TCI-state set corresponding to the time-frequency resource for non-SBFD.

[0140] Optionally, the second higher layer signaling may be RRC signaling.

[0141] In the embodiment shown in Figure 3, the network device sends an activation indication signaling to the terminal device, and indicates the activation and / or deactivation of at least one transmission configuration indication state corresponding to at least one time-frequency resource through the 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.

[0142] Please refer to FIG8 , which is a flowchart of another communication processing method provided by an embodiment of the present application. The method may include but is not limited to the following steps:

[0143] 801. The network device sends a first higher-layer signaling to the terminal device. Correspondingly, the terminal device receives the first higher-layer signaling from the network device.

[0144] 802. 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.

[0145] 803. The terminal device responds to the activation indication signaling and transmits based on the activated TCI-state.

[0146] The activation indication signaling is used to indicate activation and / or deactivation of at least one TCI-state, where the at least one TCI-state is a TCI-state corresponding to at least one time-frequency resource, and the at least one TCI-state has a one-to-one correspondence with the at least one time-frequency resource. The first higher-layer signaling is used to configure an associated TCI-state of the first TCI-state, where the at least one TCI-state includes the first TCI-state. Optionally, the first higher-layer signaling may be RRC signaling.

[0147] 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 higher-layer signaling may be used to configure an associated TCI-state for each TCI-state in the first TCI-state set.

[0148] 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.

[0149] 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, based on the first higher layer signaling, that the first TCI-state has an associated TCI-state, thereby activating the TCI-state including the first transmission configuration indication and the associated TCI-state of the first TCI-state.

[0150] 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-layer signaling configures TCI-state 1 to associate with 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.

[0151] 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 the shared TCI-state corresponding to the SBFD time-frequency resources of trp1 and trp2, and TCI-state 4 can be the 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 shared TCI-state corresponding to the SBFD and non-SBFD time-frequency resources of trp1, and TCI-state4 can be a shared TCI-state corresponding to the SBFD and non-SBFD time-frequency resources of trp2.
