[0094] In some embodiments, access network devices, core network devices, or network devices can be replaced by terminals. For example, embodiments of this disclosure can also be applied to structures where communication between access network devices, core network devices, or network devices and terminals is replaced by communication between multiple terminals (e.g., device-to-device (D2D), vehicle-to-everything (V2X), etc.).

[0099] Figure 1A This is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0100] like Figure 1A As shown, the communication system 100 includes a terminal 101 and a network device 102.

[0101] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0102] In some embodiments, network device 102 includes, but is not limited to, at least one of access network device and core network device.

[0103] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0104] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0105] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0106] In some embodiments, the core network equipment may be a single device comprising multiple network elements, or it may be multiple devices or a group of devices, each comprising all or part of the multiple network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0107] In some embodiments, the network device can configure an uplink subband (UL subband) on a downlink (DL) time unit or a flexible time unit. The terminal can transmit uplink data on the UL subband, and the time-frequency domain resources of the UL subband can be determined through explicit configuration.

[0108] In some embodiments, the network device can configure a downlink subband (DL subband) on an uplink (UL) time unit or a flexible time unit. The terminal can receive downlink data on the DL subband, and the time-frequency domain resources of the DL subband can be determined through explicit configuration.

[0109] For example Figure 1B As shown, downlink time units or flexible time units configured with uplink subbands can be called SBFD time units, such as slot#(n+1), slot#(n+2), and slot#(n+3). Uplink time units that can only perform uplink transmission or downlink time units that can only perform downlink transmission are called non-subband full-duplex (non-SBFD) time units, for example... Figure 1B slot#n, slot#(n+4), slot#(n+5) in .

[0110] In the SBFD time unit, the terminal can transmit uplink data on the UL subband. If other terminals are present, such as legacy terminals receiving downlink data in the DL subband, the terminals may adjust the transmit beam or transmit power on the UL subband to reduce interference with downlink data reception. In the non-SBFD time unit, all terminals within the cell transmit uplink data, eliminating the aforementioned inter-terminal interference issue. This results in different uplink power control and / or uplink beam usage between the SBFD and non-SBFD time units.

[0111] For network devices, in the SBFD time unit, the network device may need to receive uplink data and transmit downlink data simultaneously, while in the non-SBFD time unit, the network device only needs to receive uplink data or transmit downlink data. The network device may use different antenna configurations in the SBFD time unit and the non-SBFD time unit, thus corresponding to different spatial relationships. This also leads to the need for the network device to configure different power control parameters and / or spatial relationships in the SBFD time unit and the non-SBFD time unit.

[0112] In the relevant mechanism, in order to achieve joint indication of uplink and / or downlink transmission, as well as power control and / or spatial relationships, a unified transmission configuration indicator (unified TCI) framework is introduced. The terminal can determine the power control parameters and spatial relationships corresponding to data transmission based on the TCI configuration.

[0113] In SBFD scenarios, the power control parameters corresponding to the uplink data transmitted by the terminal in SBFD and non-SBFD time units vary depending on the spatial relationships. Introducing the unifiedTCI framework into SBFD scenarios can achieve efficient indication of power control parameters and / or spatial relationships.

[0114] In the unified TCI framework, the terminal configures TCI states (TCI-State) or uplink TCI states (TCI-UL-State) based on the downlink or joint TCI-StateList (dl-OrJointTCI-StateList), corresponding to uplink channels or uplink signals, such as the Physical Uplink Shared Channel (PUSCH), the Physical Uplink Control Channel (PUCCH), and the Sounding Reference Signal (SRS), or corresponding to other channels or signals, such as downlink channels or downlink signals, indicating one or two TCI-States, as follows:

[0115] The path loss reference signal (PLRS) for uplink channels or uplink signals such as SRS (providing SRS that conforms to the uniform TCI state), PUSCH, PUCCH (or downlink channels or downlink signals such as PDSCH, PDCCH, positioning reference signal PRS) q d Determined based on the indicated TCI state (TCI-State) or TCI-UL-State;

[0116] If a TCI-State or TCI-UL-State configuration is provided for the uplink channel or uplink signal (or downlink channel or downlink signal), the terminal determines the corresponding P0, Alpha, and l based on the indicated TCI-State or TCI-UL-State;

[0117] In some scenarios, the terminal determines the uplink signal, such as P0, Alpha, and l corresponding to SRS, based on the indicated TCI-State or TCI-UL-State.

[0118] Wherein, P0 is the target received power, Alpha is the path loss adjustment parameter, and l is the closed-loop power control index.

[0119] For data transmissions not scheduled by DCI, such as PUCCH or PUSCH, based on RRC parameters, the appliedIndicatedTCI-State indicates at least one of three states, such as {first, second, both}. These three states correspond to the data transmission being applied to one of the first TCI, the second TCI, or both TCIs, respectively. When the RRC parameter indicates two TCIs (both), these two TCIs can be determined or indicated based on the same data TCI state.

[0120] For periodic or semi-static SRS, dynamic TCI indication based on DCI is not supported. Therefore, the TCI applied to the SRS is determined based on predefined rules: based on the TCI state corresponding to the SRS resource with the smallest identifier in the corresponding SRS resource set.

[0121] In order to determine the corresponding TCI status parameters in the SBFD scenario, this disclosure provides the following methods for determining the status, as well as terminals, network devices, systems, and storage media.

[0122] Figure 2 This is an interactive schematic diagram illustrating a method for determining a state according to embodiments of this disclosure. Figure 2 As shown, embodiments of this disclosure relate to a method for determining a state, the method including:

[0123] In step S2101, terminal 101 determines the time unit type corresponding to the data transmission.

[0124] In some embodiments, data transmission includes, but is not limited to, at least one of the following: uplink transmission; downlink transmission.

[0125] In one example, the uplink transmission may include, but is not limited to, at least one of the following: PUSCH; PUCCH; SRS.

[0126] In one example, downlink transmission may include, but is not limited to, at least one of the following: PDSCH; PDCCH; Channel State Information-Reference Signal (CSI-RS); Synchronization Signal and PBCH block (SSB).

[0127] In some embodiments, the time unit type includes, but is not limited to, a first type and a second type. The first type can be SBFD, and the second type can be non-SBFD. Alternatively, the first type can be non-SBFD, and the second type can be SBFD; this disclosure does not limit this.

[0128] Here, SBFD time unit refers to a downlink time unit or flexible time unit configured with an uplink subband, for example... Figure 1B The slots are slot#(n+1), slot#(n+2), and slot#(n+3). Of course, SBFD time units can also refer to uplink time units or flexible time units configured with downlink subbands.

[0129] Among them, the non-SBFD time unit can be an uplink time unit that is not configured with an uplink subband or a downlink subband and can only perform uplink transmission, or a downlink time unit that can only perform downlink transmission. For example Figure 1B slot#n, slot#(n+4), slot#(n+5) in .

[0130] In some embodiments, the time unit in this disclosure may be a symbol, slot, sub-slot, frame, subframe, etc., and this disclosure does not limit it.

[0131] A sub-slot can include k consecutive symbols belonging to the same slot. Here, k is a positive integer.

[0132] In some embodiments, terminal 101 may determine the time unit type corresponding to data transmission in the following manner:

[0133] Case 1: The data transmission timing i includes only one type of time unit.

[0134] Here, the timing of data transmission i can refer to any timing of data transmission.

[0135] The timing of this data transmission, i, can refer to an index within a frame that has a System Frame Number (SFN). Within a time slot, starting from symbol S of that time slot, L consecutive symbols are occupied. L is a positive integer. The data is transmitted within that time slot starting from symbol S, occupying L consecutive symbols. The data includes, but is not limited to, PUSCH, PUCCH, SRS, and Physical Random Access Channel (PRACH).

[0136] In one example, the data transmission timing i includes only the first type of time unit. The number of the first type of time units can be one or more. Then, the terminal 101 can determine that the time unit type corresponding to the data transmission is the first type.

[0137] In one example, if the data transmission timing i includes only the second type of time unit, and the number of the second type of time unit can be one or more, then the terminal 101 can determine that the time unit type corresponding to the data transmission is the second type.

[0138] Timing i may include one or more time units:

[0139] For example, terminal 101 can determine the time domain location of different types of time units based on the configuration of network device 102 and the corresponding rules.

[0140] If terminal 101 performs data transmission on an SBFD time unit based on scheduling, terminal 101 determines that the time unit type corresponding to the data transmission is SBFD. If terminal 101 performs data transmission on a non-SBFD time unit based on scheduling, terminal 101 determines that the time unit type corresponding to the data transmission is non-SBFD.

[0141] Taking a DCI-scheduled PUSCH as an example, if terminal 101 determines that the PUSCH will be transmitted in time unit #1 based on DCI scheduling information, then if the terminal determines that time unit #1 is an SBFD time unit based on the configuration of network device 102 and / or predefined rules, then the terminal determines that the PUSCH will be transmitted in the SBFD time unit. For example, transmission occurs within the UL subband frequency domain corresponding to time unit #1.

[0142] Conversely, if terminal 101 determines that time unit #1 is a non-SBFD time unit based on the configuration of network device 102 or corresponding predefined rules, then terminal 101 determines that the PUSCH is transmitted on the non-SBFD time unit. For example, it is transmitted within the frequency domain of the uplink bandwidth part (ULBWP) corresponding to time unit #1.

[0143] Within timing i, multiple time units of the same type may be included:

[0144] If terminal 101 performs data transmission on multiple consecutive SBFD time units based on scheduling, terminal 101 determines that the time unit type corresponding to the data transmission is SBFD. If terminal 101 performs data transmission on multiple non-SBFD time units based on scheduling, terminal 101 determines that the time unit type corresponding to the data transmission is non-SBFD.

[0145] Case 2: The timing of data transmission i includes two types of time units.

[0146] In one example, the time unit type corresponding to the data transmission is determined to be either the first type or the second type, i.e., SBFD or non-SBFD.

[0147] For example, terminal 101 can determine the time unit type corresponding to the data transmission based on the type of the m-th time unit within the data transmission timing i.

[0148] Where m can be a positive integer.

[0149] For example, if m is 1, terminal 101 can determine the type of time unit corresponding to data transmission based on the type of the first time unit within time i.

[0150] If the first time unit within timing i is an SBFD time unit, then the time unit type corresponding to the data transmission is SBFD. If the first time unit within timing i is a non-SBFD time unit, then the time unit type corresponding to the data transmission is SBFD.

[0151] For example, terminal 101 can determine the type of time unit corresponding to the data transmission based on the type of a large number of time units within the data transmission timing i.

[0152] For example, if timing i includes 5 time units, of which 3 are SBFD time units and 2 are non-SBFD time units, then terminal 101 determines that the time unit type corresponding to the data transmission is SBFD.

[0153] For example, terminal 101 can determine the time unit type corresponding to data transmission based on a predefined method.

[0154] For example, in order to make better use of subband resources, terminal 101 can directly determine that the time unit type corresponding to the data transmission is SBFD.

[0155] For example, in order to reduce the scheduling complexity of network devices and reduce interference between terminals, terminal 101 can directly determine that the time unit type corresponding to data transmission is non-SBFD.

[0156] In one example, determining the time unit type corresponding to the data transmission includes the first type and the second type, namely SBFD and non-SBFD.

[0157] The above is merely an illustrative example, and this disclosure does not limit the scheme for determining the time unit type corresponding to data transmission.

[0158] In step S2102, network device 102 determines the time unit type corresponding to the data transmission.

[0159] In some embodiments, the network device 102 determines the time unit type corresponding to the data transmission in a similar way to the terminal 101, and will not be described again here.

[0160] In step S2103a, network device 102 determines one or more TCI status lists.

[0161] In some embodiments, network device 102 may determine one or more TCI status lists based on a predefined method.

[0162] In one example, one or more TCI state lists can be defined by the protocol. Each TCI state list can include one or more TCI states.

[0163] In one example, a TCI state list can be defined by the protocol, and the TCI states in the TCI state list can be used for uplink and downlink transmissions.

[0164] In one example, the protocol can define multiple TCI state lists, such as two TCI state lists. One list contains TCI states that can be used for uplink transmission, while the other list contains TCI states that can be used for downlink transmission.

[0165] In one example, the protocol can define multiple TCI state lists, such as four TCI state lists. Two of these lists contain TCI states that can be used for uplink transmission (corresponding to SBFD time units and non-SBFD time units, respectively), while the other two lists contain TCI states that can be used for downlink transmission (corresponding to SBFD time units and non-SBFD time units, respectively).

[0166] In one example, the number of TCI status lists can be greater, and this disclosure does not limit this.

[0167] In some embodiments, network device 102 may configure one or more TCI status lists.

[0168] The above is merely an illustrative example, and this disclosure does not limit the method by which network device 102 determines the TCI status list.

[0169] In step S2103b, network device 102 sends a second instruction signaling to terminal 101.

[0170] In some embodiments, terminal 101 may receive a second instruction signaling.

[0171] In some embodiments, the second indication signaling is used to indicate one or more TCI status lists configured in the network device 102. Each TCI status list may include one or more TCI states.

[0172] In some embodiments, the second indication signaling may be Radio Resource Control (RRC) signaling.

[0173] In one example, the second indication signaling can indicate a TCI status list, in which the TCI statuses can be used for uplink and downlink transmissions.

[0174] In one example, the second indication signaling can indicate multiple TCI status lists, such as two TCI status lists, where one list contains TCI statuses that can be used for uplink transmissions and the other list contains TCI statuses that can be used for downlink transmissions.

[0175] In one example, the second indication signaling can indicate multiple TCI status lists, such as four TCI status lists, where two lists contain TCI statuses that can be used for uplink transmission (corresponding to SBFD time units and non-SBFD time units, respectively), and the other two lists contain TCI statuses that can be used for downlink transmission (corresponding to SBFD time units and non-SBFD time units, respectively).

[0176] In some embodiments, step S2103b is an optional execution step. For example, if both network device 102 and terminal 101 determine one or more TCI status lists based on a predefined method, step S2103b may not be executed.

[0177] In some embodiments, both steps S2103a and S2103b can be executed. For example, when the network device 102 has configured one or more TCI status lists and then informs the terminal through the second indication signaling, steps S2103a and S2103b can be executed.

[0178] In step S2104, terminal 101 determines one or more TCI status lists.

[0179] In some embodiments, terminal 101 determines one or more TCI status lists based on a predefined method.

[0180] In one example, a TCI state list can be defined by the protocol, and the TCI states in the TCI state list can be used for uplink and downlink transmissions.

[0181] In one example, the protocol can define multiple TCI state lists, such as two TCI state lists. One list contains TCI states that can be used for uplink transmission, while the other list contains TCI states that can be used for downlink transmission.

[0182] In one example, the protocol can define multiple TCI state lists, such as four TCI state lists. Two of these lists contain TCI states that can be used for uplink transmission (corresponding to SBFD time units and non-SBFD time units, respectively), while the other two lists contain TCI states that can be used for downlink transmission (corresponding to SBFD time units and non-SBFD time units, respectively).

[0183] In some embodiments, terminal 101 determines one or more TCI status lists based on a second indication signaling sent by network device 102.

[0184] In one example, the second indication signaling can indicate a TCI status list, in which the TCI statuses can be used for uplink and downlink transmissions.

[0185] In one example, the second indication signaling can indicate multiple TCI status lists, such as two TCI status lists, where one list contains TCI statuses that can be used for uplink transmissions and the other list contains TCI statuses that can be used for downlink transmissions.

[0186] In one example, the second indication signaling can indicate multiple TCI status lists, such as four TCI status lists, where two lists contain TCI statuses that can be used for uplink transmission (corresponding to SBFD time units and non-SBFD time units, respectively), and the other two lists contain TCI statuses that can be used for downlink transmission (corresponding to SBFD time units and non-SBFD time units, respectively).

[0187] In some embodiments, terminal 101 determines one or more TCI status lists based on a predefined method and a second indication signaling sent by network device 102.

[0188] In one example, terminal 101 determines one or more TCI status lists based on protocol conventions, and then determines one or more of the aforementioned TCI status lists based on second instruction signaling.

[0189] In step S2105a, network device 102 determines the TCI state corresponding to each type of time unit.

[0190] In some embodiments, network device 102 may determine the TCI state corresponding to each type of time unit based on a predefined method.

[0191] In one example, the TCI state determined here could refer to the active TCI state corresponding to each type of time unit.

[0192] In some embodiments, network device 102 can determine the TCI state corresponding to each type of time unit based on n TCI states in each TCI state list.

[0193] In one example, n is a positive integer.

[0194] For example, network device 102 can determine the TCI states corresponding to SBFD time units and non-SBFD time units based on one of the TCI states in each TCI state list, such as the first TCI state.

[0195] Assuming the number of TCI state lists is 1, network device 102 determines the first TCI state in the TCI state list as the active TCI state corresponding to the SBFD time unit and the non-SBFD time unit.

[0196] Assuming there are two TCI state lists, each corresponding to a transmission direction (e.g., TCI state list #1 corresponds to uplink transmission, and TCI state list #2 corresponds to downlink transmission), network device 102 will determine the first TCI state in TCI state list #1 corresponding to uplink transmission as the active uplink TCI state corresponding to the SBFD time unit and non-SBFD time unit. Similarly, it will determine the first TCI state in TCI state list #2 corresponding to downlink transmission as the active downlink TCI state corresponding to the SBFD time unit and non-SBFD time unit.

[0197] Understandably, one of the two TCI status lists can correspond to TRP#1, and the other can correspond to TRP#2. The TCI status in each TCI status list can be applied to both uplink and downlink transmissions. In this case, the first TCI status in the TCI status list corresponding to TRP#1 can be used as the TCI status corresponding to the SBFD time unit and non-SBFD, and the first TCI status in the TCI status list corresponding to TRP#2 can be used as the TCI status corresponding to the SBFD time unit and non-SBFD time unit.

[0198] Assuming there are four TCI state lists, with two TCI state lists corresponding to uplink transmissions and the other two corresponding to downlink transmissions, network device 102 will determine the available uplink TCI states for SBFD and non-SBFD based on the first TCI state from the two TCI state lists corresponding to uplink transmissions. Similarly, it will determine the available downlink TCI states for SBFD and non-SBFD based on the first TCI state from the two TCI state lists corresponding to downlink transmissions.

[0199] Understandably, two of the four TCI status lists can correspond to TRP#1, and the other two can correspond to TRP#2. Each TCI status in the TCI status list can be applied to both uplink and downlink transmissions. In this case, the first TCI status in one of the TCI status lists corresponding to TRP#1 (or TRP#2) can be used as the TCI status for the corresponding SBFD time unit, and the first TCI status in the other TCI status list corresponding to TRP#1 (or TRP#2) can be used as the TCI status for the corresponding non-SBFD time unit.

[0200] The number of TCI status lists can also be greater, and this disclosure does not limit this.

[0201] In step S2105b, network device 102 sends a first instruction signaling to terminal 101.

[0202] In some embodiments, terminal 101 receives a first instruction signaling.

[0203] In some embodiments, the first indication signaling is used to indicate the TCI status corresponding to each type of time unit.

[0204] In some embodiments, the first instruction signaling can be any of the following: RRC signaling; MAC CE; DCI.

[0205] In some embodiments, data transmission corresponds to the same transmission configuration across multiple types of time units. For example, SBFD time units and non-SBFD time units correspond to the same transmission configuration. The transmission configuration may include, but is not limited to, a TCI status list or a TCI configuration for a specific uplink data transmission or a specific downlink data transmission.

[0206] The data transfer configuration can include configuration authorization configuration (ConfigGrant-config, CG-config), PUCCH configuration (PUCCH configuration), PUSCH configuration (PUSCH configuration), etc.

[0207] Accordingly, the first instruction signaling can be used to instruct at least one of the following:

[0208] The first type of time unit and the second type of time unit apply the same TCI state;

[0209] The first type of time unit and the second type of time unit apply different TCI states.

[0210] In one example, the first indication signaling can be used to instruct SBFD time units and non-SBFD time units to apply the same TCI state.

[0211] In one example, the first indication signaling can be used to instruct the SBFD time unit and the non-SBFD time unit to apply different TCI states respectively.

[0212] For example, the first indication signaling can indicate the number of TCI states corresponding to each type of time unit. For instance, a type of time unit can correspond to one TCI state, or a type of time unit can correspond to two or more TCI states. For example, an SBFD time unit can correspond to one TCI state, and a non-SBFD time unit can correspond to two TCI states.

[0213] In one example, when the first indication signaling is used to indicate that different TCI states are applied to SBFD time units and non-SBFD time units respectively, network device 102 can determine the TCI state applied on each type of time unit.

[0214] For example, the same TCI state (or the same set of TCI states) can be applied to both SBFD and non-SBFD time units.

[0215] For example, the same TCI state (or the same set of TCI states) can be applied to the SBFD time unit, ignoring the non-SBFD time unit.

[0216] For example, the same TCI state (or the same set of TCI states) can be applied to non-SBFD time units, ignoring SBFD time units.

[0217] For example, in the two TCI states (or two sets of TCI states), the first TCI state (or the first set of TCI states) can be applied to the SBFD time unit, and the second TCI state (or the second set of TCI states) can be applied to the non-SBFD time unit.

[0218] For example, in the two TCI states (or two sets of TCI states), the first TCI state (or the first set of TCI states) can be applied to the SBFD time unit, and the second TCI state (or the second set of TCI states) can be applied to the non-SBFD time unit.

[0219] For example, network device 102 can determine the first TCI state in a TCI state list corresponding to the SBFD time unit and the non-SBFD time unit as the TCI state applied on the SBFD time unit, and determine the second TCI state in the TCI state list as the TCI state applied on the non-SBFD time unit.

[0220] For example, the index of the first TCI state can be greater than the index of the second TCI state.

[0221] For example, the index of the first TCI state may be smaller than the index of the second TCI state.

[0222] For example, in the TCI state list corresponding to the uplink transmission, the position index corresponding to the first TCI state is less than the position index corresponding to the second TCI state.

[0223] For example, in the TCI state list corresponding to the uplink transmission, the position index corresponding to the first TCI state is greater than the position index corresponding to the second TCI state.

[0224] For example, in the TCI state list corresponding to the downlink transmission, the position index corresponding to the first TCI state is less than the position index corresponding to the second TCI state.

[0225] For example, in the TCI state list corresponding to the downlink transmission, the position index corresponding to the first TCI state is greater than the position index corresponding to the second TCI state.

[0226] For example, the index of the first TCI state and the index of the second TCI state can be determined based on MAC CE or RRC signaling.

[0227] For example, the location index corresponding to the first TCI state and the location index corresponding to the second TCI state can be determined based on MAC CE or RRC signaling.

[0228] In one example, when the first indication signaling is used to indicate that SBFD time units and non-SBFD time units apply different TCI states (or different groups of TCI states), the network device 102 can indicate the TCI state corresponding to each type of time unit through the first indication signaling.

[0229] For example, TCI state #1 is applied to the SBFD time unit, and TCI state #2 is applied to the non-SBFD time unit.

[0230] In some embodiments, data transmission corresponds to different transmission configurations on multiple types of time units. These transmission configurations may include, but are not limited to, TCI status lists or TCI configurations for specific uplink or downlink data transmissions.

[0231] For example, SBFD time units and non-SBFD time units correspond to different transmission configurations, where the transmission configuration may include, but is not limited to, a TCI status list or a TCI configuration for a specific uplink data transmission or a specific downlink data transmission.

[0232] In one example, network device 102 can indicate different transmission configurations corresponding to each type of time unit through a first indication signaling, such as TCI status list #1 corresponding to SBFD time unit and TCI status list #2 corresponding to non-SBFD time unit.

[0233] In one example, network device 102 can determine that the transmission configuration corresponding to each type of time unit can only be applied to that type of time unit.

[0234] For example, the TCI states in TCI state list #1 corresponding to the SBFD time unit are only applied to the SBFD time unit.

[0235] For example, the TCI states in list #2 of TCI states corresponding to non-SBFD time units are only applied to non-SBFD time units.

[0236] In some embodiments, network device 102 can configure the TCI state corresponding to each type of time unit. In some embodiments, step S2105b is an optional execution step. For example, if both network device 102 and terminal 101 determine the TCI state corresponding to each type of time unit based on a predefined method, step S2105b may not be executed.

[0237] In some embodiments, both steps S2105a and S2105b can be executed. For example, if the network device 102 configures the possible TCI states corresponding to each type of time unit and then informs the terminal through the first indication information, steps S2105a and S2105b can be executed.

[0238] In step S2106, terminal 101 determines the TCI state corresponding to each type of time unit.

[0239] In some embodiments, the TCI state determined here may refer to the active TCI state for each type of time unit.

[0240] In some embodiments, terminal 101 may determine the active TCI state for each type of time unit based on a predefined method.

[0241] In one example, terminal 101 can determine the active TCI state corresponding to each type of time unit based on n TCI states in each TCI state list. Here, n is a positive integer.

[0242] For example, terminal 101 can determine the available TCI states corresponding to SBFD time units and non-SBFD time units based on one of the TCI state lists, such as the first TCI state.

[0243] Assuming the number of TCI state lists is 1, terminal 101 can determine the first TCI state in the TCI state list as the active TCI state corresponding to the SBFD time unit and the non-SBFD time unit.

[0244] Assuming the TCI state list has two entries, terminal 101 can determine the first TCI state in the corresponding uplink transmission TCI state list as the active uplink TCI state corresponding to the SBFD time unit and the non-SBFD time unit. Similarly, it can determine the first TCI state in the corresponding downlink transmission TCI state list as the active downlink TCI state corresponding to the SBFD time unit and the non-SBFD time unit.

[0245] Assuming the number of TCI state lists is 4, terminal 101 will determine the active uplink TCI state corresponding to SBFD and non-SBFD for the first TCI state in the two TCI state lists corresponding to uplink transmission, respectively. Similarly, it will determine the active downlink TCI state corresponding to SBFD and non-SBFD for the first TCI state in the two TCI state lists corresponding to downlink transmission, respectively.

[0246] The above is only an illustrative example. Terminal 101 can also determine the TCI state corresponding to different types of time units based on the mTRP scenario.

[0247] In some embodiments, terminal 101 may determine the TCI status of each type of time unit based on the first indication signaling sent by network device 102.

[0248] In one example, data transmission corresponds to the same transmission configuration across multiple types of time units. For example, the same transmission configuration corresponds to both SBFD and non-SBFD time units. The transmission configuration may include, but is not limited to, a TCI status list or a TCI configuration for a specific uplink data transmission or a specific downlink data transmission.

[0249] The first instruction signaling is used to instruct the first type of time unit and the second type of time unit to apply the same TCI state, or the first type of time unit and the second type of time unit to apply different TCI states respectively.

[0250] For example, when the first type of time unit and the second type of time unit apply the same TCI state, the terminal 101 can determine the TCI state applied on the SBFD time unit and the non-SBFD time unit based on a predefined method or the first indication signaling sent by the network device 102.

[0251] For example, terminal 101 can determine the first TCI state in TCI list #1 (which corresponds to both SBFD and non-SBFD time units) as the TCI state applied in both SBFD and non-SBFD time units based on a predefined method.

[0252] For example, terminal 101 can determine the TCI state applied in the SBFD time unit and the non-SBFD time unit based on the display signaling sent by network device 102, such as the first indication signaling. For example, the first indication signaling indicates that the TCI state applied in the SBFD time unit and the non-SBFD time unit is TCI state #2 in the TCI state list.

[0253] For example, when the first type of time unit and the second type of time unit apply different TCI states, the terminal 101 can determine the TCI states applied on the SBFD time unit and the non-SBFD time unit respectively based on a predefined method or the indication signaling sent by the network device 102.

[0254] For example, a first indication signaling or a separate third indication signaling can indicate the application of one or more TCI states on an SBFD time unit, and different one or more TCI states can be applied on a non-SBFD time unit. For example, TCI state #1 can be applied on an SBFD time unit, and TCI state #2 can be applied on a non-SBFD time unit.

[0255] For example, terminal 101 can determine the first TCI state in a TCI state list corresponding to the SBFD time unit and the non-SBFD time unit as the TCI state applied on the SBFD time unit, and determine the second TCI state in the TCI state list as the TCI state applied on the non-SBFD time unit.

[0256] For example, the index of the first TCI state can be greater than the index of the second TCI state.

[0257] For example, the index of the first TCI state may be smaller than the index of the second TCI state.

[0258] For example, the index of the first TCI state can be greater than the index of the second TCI state.

[0259] For example, in the TCI state list corresponding to the uplink transmission, the position index corresponding to the first TCI state is less than the position index corresponding to the second TCI state.

[0260] For example, in the TCI state list corresponding to the uplink transmission, the position index corresponding to the first TCI state is greater than the position index corresponding to the second TCI state.

[0261] For example, in the TCI state list corresponding to the downlink transmission, the position index corresponding to the first TCI state is less than the position index corresponding to the second TCI state.

[0262] For example, in the TCI state list corresponding to the downlink transmission, the location index corresponding to the first TCI state is greater than the location index corresponding to the second TCI state. For example, the indexes of the first and second TCI states can be determined based on MAC CE or RRC signaling.

[0263] For example, the location index corresponding to the first TCI state and the location index corresponding to the second TCI state can be determined based on MAC CE or RRC signaling.

[0264] In one example, when the first indication signaling is used to indicate that different TCI states are applied to SBFD time units and non-SBFD time units respectively, network device 102 can inform terminal 101 of the TCI state applied on each type of time unit through the first indication signaling.

[0265] In some embodiments, data transmission corresponds to different transmission configurations on multiple types of time units. For example, SBFD time units and non-SBFD time units correspond to different transmission configurations. The transmission configuration may include, but is not limited to, a TCI status list or a TCI configuration for a specific uplink data transmission or a specific downlink data transmission.

[0266] In one example, terminal 101 can determine the TCI state corresponding to SBFD time unit and non-SBFD time unit respectively from different TCI state lists.

[0267] In one example, terminal 101 can determine the uplink TCI status corresponding to the SBFD time unit in the uplink transmission TCI configuration corresponding to the SBFD time unit type, and determine the uplink TCI status corresponding to the non-SBFD time unit in the uplink transmission TCI configuration corresponding to the non-SBFD time unit type.

[0268] In one example, terminal 101 can determine the downlink TCI state corresponding to the SBFD time unit in the TCI configuration of downlink transmission of the corresponding SBFD time unit type, and determine the downlink TCI state corresponding to the non-SBFD time unit in the TCI configuration of downlink transmission of the corresponding non-SBFD time unit type.

[0269] In one example, terminal 101 can determine that the transmission configuration corresponding to each type of time unit can only be applied to that type of time unit.

[0270] For example, the TCI states in TCI state list #1 corresponding to the SBFD time unit are only applied to the SBFD time unit.

[0271] For example, the TCI states in list #2 of TCI states corresponding to non-SBFD time units are only applied to non-SBFD time units.

[0272] In some embodiments, terminal 101 may determine the available or possible TCI status for each type of time unit based on a predefined method and a first indication signaling sent by network device 102.

[0273] The above is merely an illustrative example, and this disclosure does not limit the process by which terminal 101 determines the available or possible TCI state for each type of time unit.

[0274] In step S2107, terminal 101 determines the TCI state corresponding to the data transmission.

[0275] In some embodiments, terminal 101 may determine the actual TCI state corresponding to the data transmission based on the time unit type corresponding to the data transmission and the TCI state corresponding to the time unit type.

[0276] In one example, the actual TCI state corresponding to the data transmission determined at this time can be one or more of the previously activated TCI states. The specific number of TCI states is not limited in this disclosure.

[0277] In some embodiments, the time unit type corresponding to the data transmission is SBFD, and the data transmission corresponds to the same transmission configuration on multiple types of time units. Specifically, the SBFD time unit and the non-SBFD time unit correspond to TCI state #1, so the terminal 101 can determine that the TCI state corresponding to the data transmission is TCI state #1.

[0278] In some embodiments, the time unit type corresponding to the data transmission is non-SBFD. The data transmission corresponds to the same transmission configuration in multiple time units. Specifically, the SBFD time unit and the non-SBFD time unit correspond to TCI state #1. Then, the terminal 101 can determine that the TCI state corresponding to the data transmission is TCI state #1.

[0279] In some embodiments, the time unit type corresponding to the data transmission is SBFD. The data transmission corresponds to different transmission configurations on various types of time units. Specifically, the SBFD time unit and the non-SBFD time unit correspond to TCI state #1 and TCI state #2, respectively. Then, the terminal 101 can determine that the TCI state corresponding to the data transmission is TCI state #1.

[0280] In some embodiments, the time unit type corresponding to the data transmission is non-SBFD. The data transmission corresponds to different transmission configurations on various types of time units. Specifically, the SBFD time unit and the non-SBFD time unit correspond to TCI state #1 and TCI state #2, respectively. Then, the terminal 101 can determine that the TCI state corresponding to the data transmission is TCI state #2.

[0281] In some embodiments, the time unit type corresponding to the data transmission includes a first type and a second type. The data transmission corresponds to the same transmission configuration on multiple types of time units. Specifically, the SBFD time unit and the non-SBFD time unit correspond to TCI state #1. Then, the terminal 101 can determine that the TCI state corresponding to the data transmission is TCI state #1.

[0282] In some embodiments, the time unit type corresponding to data transmission includes a first type and a second type. Data transmission corresponds to different transmission configurations on multiple types of time units. Specifically, the SBFD time unit and the non-SBFD time unit correspond to TCI state #1 and TCI state #2, respectively. Then, the terminal 101 can determine that the TCI state corresponding to data transmission is TCI state #1 and TCI state #2.

[0283] In some embodiments, the time unit type corresponding to data transmission includes a first type and a second type. Data transmission corresponds to different transmission configurations on multiple types of time units. Specifically, the SBFD time unit and the non-SBFD time unit correspond to TCI state #1 and TCI state #2, respectively. At this time, the terminal 101 can determine that the TCI state corresponding to data transmission is unrelated to the time unit corresponding to data transmission.

[0284] The fact that the second TCI state is independent of the time unit type corresponding to the data transmission can mean that the second TCI state actually used for data transmission is no longer determined based on the time unit type corresponding to the data transmission.

[0285] In one example, terminal 101 can fall back to the traditional mechanism to determine the second TCI state.

[0286] For example, terminal 101 can determine the TCI state corresponding to the data transmission according to relevant mechanisms, such as the TCI state (TCI-State) or uplink TCI state (TCI-UL-State) configured in the downlink or joint TCI state list (dl-OrJointTCI-StateList).

[0287] In step S2108, network device 102 determines the TCI state corresponding to the data transmission.

[0288] In some embodiments, the network device 102 determines the TCI state corresponding to the data transmission in a manner similar to the implementation process of the aforementioned step S2109, and will not be described again here.

[0289] In step S2109, terminal 101 performs data transmission processing.

[0290] In some embodiments, terminal 101 performs uplink data transmission processing.

[0291] In some embodiments, data transmission corresponds to different transmission configurations for multiple types of time units, and the transmission configuration corresponding to a certain type of time unit is only applied to that type of time unit. Considering configuration flexibility, it may not be possible to restrict data transmission to only a certain type of time unit through configuration; for example, it may not be possible to restrict PUSCH to only be transmitted on SBFD or non-SBFD time units. In this case, terminal 101 can use the following data transmission processing:

[0292] Method 1: If data from a certain type of time unit needs to be transmitted on another type of time unit based on configuration, terminal 101 can cancel the data transmission.

[0293] For example, the transmission configuration is a first transmission configuration, which is a transmission configuration corresponding to a first type of time unit. The time unit type corresponding to the data transmission includes a second type. For example, the time unit type corresponding to the data transmission is a second type, or a first type and a second type. In this case, the terminal 101 can cancel the data transmission.

[0294] For example, the transmission configuration is a second transmission configuration, which is a transmission configuration corresponding to a second type of time unit. The time unit type corresponding to the data transmission includes a first type. For example, the time unit type corresponding to the data transmission is a first type, or a first type and a second type. In this case, the terminal 101 can cancel the data transmission.

[0295] For example, if a data transmission configuration corresponding to a specific time unit, such as a data transmission configuration for a non-SBFD time unit, is transmitted on an SBFD time unit, the terminal can cancel the data transmission.

[0296] For example, if the data transmission of an SBFD time unit is configured to be transmitted on a non-SBFD time unit, the terminal cancels the data transmission.

[0297] Method 2: Terminal 101 can transmit data only on this type of time unit.

[0298] For example, the transmission configuration is a first transmission configuration, which is a transmission configuration corresponding to a first type of time unit. The time unit type corresponding to the data transmission includes the second type. The second type of time unit is skipped, and data transmission is performed on the subsequent first type of time unit, for example, data transmission is performed on the next first type of time unit.

[0299] For example, the transmission configuration is a second transmission configuration, which is a transmission configuration corresponding to a second type of time unit. The time unit type corresponding to the data transmission includes the first type. The first type of time unit is skipped, and data transmission is performed on the subsequent second type of time unit, for example, data transmission is performed on the next second type of time unit.

[0300] For example, if the data transmission configuration corresponds to a specific time unit, such as data corresponding to a non-SBFD time unit being transmitted in an SBFD time unit, the terminal can cancel the data transmission in that SBFD time unit and transmit the data in the next non-SBFD time unit.

[0301] For example, if the data transmission configuration corresponds to a specific time unit, such as data corresponding to an SBFD time unit being transmitted in a non-SBFD time unit, the terminal can cancel the data transmission in that non-SBFD time unit and transmit the data in the next SBFD time unit.

[0302] The above is merely an illustrative example, and this disclosure does not limit the specific data transmission processing method.

[0303] In step S2110, network device 102 performs data transmission processing.

[0304] In some embodiments, network device 102 performs downlink data transmission processing.

[0305] In some embodiments, if data from a certain type of time unit needs to be transmitted on another type of time unit based on a configuration, network device 102 cancels downlink data transmission. Alternatively, data transmission can be performed only on one type of time unit. The specific implementation process is similar to step S2110 and will not be described again here.

[0306] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0307] In some embodiments, the terms “downlink control information (DCI),” “downlink (DL) assignment,” “DL DCI,” “uplink (UL) grant,” and “UL DCI” can be used interchangeably.

[0311] In some embodiments, steps S2103a and S2103b may be performed selectively or both may be performed.

[0312] In some embodiments, steps S2105a and S2105b may be performed selectively or both may be performed.

[0389] In some embodiments, network device 102 sends a first instruction signaling to terminal 101.

[0390] In some embodiments, terminal 101 may receive a first instruction signaling.

[0394] In some embodiments, steps S3401 to S3404 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0395] In some embodiments, the execution order of steps S3401 to S3404 is not limited.

[0396] In the above embodiments, when data transmission corresponds to the same or different transmission configurations on multiple types of time units, the TCI state corresponding to the data transmission can be determined, thereby improving the availability of SBFD.

[0397] The above process is further illustrated with examples below.

[0398] In this embodiment of the disclosure, static configuration of TCI parameters based on different time-domain unit types can be achieved in the SBFD scenario.

[0399] Terminal side:

[0400] The terminal side determines the time unit type (e.g., SBFD time unit or non-SBFD time unit) corresponding to the data transmission based on the resource type in which the data transmission occurs, and determines the TCI state of the data transmission in the SBFD time unit and the non-SBFD time unit based on at least one of the following methods:

[0401] Method 1: The terminal determines at least one TCI state corresponding to the data transmission based on predefined rules:

[0402] The terminal determines the at least one TCI state based on the first N TCI states of the configured TCI state set or list;

[0403] Method 2: The terminal determines at least one TCI state corresponding to the data transmission based on indication signaling.

[0404] Example 1: Data transmission for SBFD and non-SBFD time units is determined based on the same data transmission configuration:

[0405] For example, data transfer configuration can be configured with authorization settings (ConfigGrant-config, CG-config), PUCCH configuration (PUCCH configuration), etc.

[0406] The instruction signaling indicates at least one of the following:

[0407] The same TCI state is applied to both SBFD and non-SBFD time units;

[0408] The different TCI states applied by SBFD time units and non-SBFD time units respectively;

[0409] Example 2: Data transmission for SBFD and non-SBFD time units is determined based on different data transmission configurations:

[0410] If the data in the SBFD (non-SBFD) time unit is based on the configuration for transmission in the non-SBFD (SBFD) time unit,

[0411] The terminal cancels the data transmission;

[0412] And / or, the terminal transmits the data in the next SBFD (non-SBFD) time unit;

[0413] Base station side:

[0414] Based on the resource type where the data transmission occurs, the base station determines the time unit type corresponding to the data transmission (e.g., SBFD time unit or non-SBFD time unit) and sends an indication signaling message to indicate the TCI state of the data transmission in the SBFD time unit and the non-SBFD time unit:

[0415] Method 1: The base station indicates the corresponding data for SBFD time units and non-SBFD time units based on the same data transmission configuration:

[0416] The instruction signaling indicates at least one of the following:

[0417] The same TCI state is applied to both SBFD and non-SBFD time units;

[0418] The different TCI states applied by SBFD time units and non-SBFD time units respectively;

[0419] Method 2: The base station configures the corresponding data for SBFD and non-SBFD time units based on different data transmission settings.

[0420] If the data in the SBFD (non-SBFD) time unit is based on the configuration for transmission in the non-SBFD (SBFD) time unit, the base station determines:

[0421] The terminal cancels the data transmission;

[0422] And / or, the terminal transmits the data in the next SBFD (non-SBFD) time unit.

[0423] The following describes the specific implementation of the present invention from the perspective of the terminal:

[0424] Implementation method:

[0425] Assuming the terminal supports SBFD, the terminal can transmit uplink data on the UL subband and / or receive downlink data on the DL subband, based on the base station configuration on the DL or flexible symbol.

[0426] Another possible implementation is that a terminal supporting SBFD can receive downlink data on the DL subband and / or transmit uplink data on the UL subband, based on the base station configuration on the UL or flexible symbol.

[0427] As described above, the terminal can determine the time domain location of the SBFD time unit based on the base station configuration and corresponding rules. If the terminal transmits data on the SBFD time unit based on scheduling, the terminal determines that the data transmission corresponds to the SBFD time unit. Taking a PUSCH scheduled by DCI as an example, if the terminal determines that the PUSCH is transmitted on time unit n based on DCI scheduling information, then if the terminal determines that time unit n corresponds to an SBFD time unit based on the base station configuration and corresponding rules, the terminal determines that the PUSCH is transmitted on the SBFD time unit. For example, transmission occurs within the UL subband frequency domain corresponding to time unit n. Conversely, if the terminal determines that the time unit is non-SBFD based on the base station configuration or corresponding predefined rules, the terminal determines that the PUSCH is transmitted on the non-SBFD time unit. For example, transmission occurs within the UL BWP frequency domain corresponding to time unit n.

[0428] Corresponding to the uplink data transmission of occasion i, if occasion i includes both SBFD time units and non-SBFD time units, the terminal determines the time unit type corresponding to occasion i based on at least one of the following methods;

[0429] The terminal determines that the occasioni corresponds to the SBFD time unit, or the terminal determines that the occasioni corresponds to the non-SBFD time unit;

[0430] The terminal determines the time unit type corresponding to occasion i based on the first time unit corresponding to occasion i. For example, if the first time unit is an SBFD time unit, the terminal determines that the time unit type corresponding to occasion i is SBFD; if the first time unit is a non-SBFD time unit, the terminal determines that the time unit type corresponding to occasion i is non-SBFD.

[0431] The terminal determines that occasion i corresponds to both SBFD time unit and non-SBFD time unit;

[0432] Alternatively, if occasion i includes both SBFD time units and non-SBFD time units, the terminal uses a unified power control mechanism for different time unit types. For example, existing mechanisms are used to determine the corresponding power control parameters.

[0433] As described above, the design scheme of this embodiment of the invention determines the TCI state of the corresponding data transmission in the SBFD time unit and the non-SBFD time unit based on a predefined or signaling indication method in the SBFD scenario.

[0434] The data transmission includes, but is not limited to, at least one of the following:

[0435] Uplink transmission, including but not limited to PUSCH, SRS, PUCCH, etc.;

[0436] Downlink transmission, including but not limited to PDCCH, PDSCH, CSI-RS, SSB, etc.

[0437] The following describes the specific solution of the present invention based on different embodiments, taking the TCI state corresponding to power control and spatial relationship as an example, which is used by the terminal to determine the TCI state of the corresponding data transmission in the SBFD time unit and / or non-SBFD time unit.

[0438] Implementation method:

[0439] As described above, the terminal determines at least one TCI state corresponding to the data transmission based on predefined rules or signaling indication methods;

[0440] For example, the terminal determines one or more corresponding TCI state lists based on predefined or signaling configuration methods. For example, the terminal determines one TCI state list, which can be applied to both uplink and downlink simultaneously. For example, the terminal determines two TCI state lists, which correspond to uplink and downlink respectively.

[0441] Implementation method 1:

[0442] Corresponding to the TCI state list, the terminal determines the first N TCI states in one or more TCI lists as the TCI states corresponding to data transmission. For example, given one TCI state list, the terminal determines the N TCI states in that list as the possible TCI states corresponding to data transmission. For example, given two TCI state lists, the terminal determines the first N TCI states in both lists as the possible TCI states corresponding to data transmission.

[0443] Implementation Method 2:

[0444] In one possible implementation, the terminal determines the TCI state for both the SBFD and non-SBFD time units based on the same data transmission configuration. This data transmission configuration can be applied to either the SBFD or non-SBFD time units. For example, the data transmission configuration can be a TCI state list or a TCI configuration for a specific data transmission; this invention does not limit this.

[0445] Based on configuration signaling, the terminal determines the TCI state applied on SBFD and non-SBFD time units. For example, the terminal receives indication signaling that indicates at least one of the following:

[0446] The same TCI state is applied to both SBFD and non-SBFD time units;

[0447] SBFD time units and non-SBFD time units are applied to different TCI states, respectively.

[0448] When the SBFD time unit and the non-SBFD time unit are applied to different TCI states, the terminal determines the TCI state corresponding to the data transmission in the SBFD time unit / non-SBFD time unit based on a predefined or signaling indication method. The specific method will not be elaborated here.

[0449] Implementation Method 3:

[0450] One possible implementation is that the terminal determines the TCI state for SBFD and non-SBFD time units based on different data transmission configurations. For example, different TCI state lists can be configured based on different time unit types; or, different TCI states can be configured based on different time unit types. This invention does not limit this approach.

[0451] One possible implementation involves data transmission configurations corresponding to specific time units, such as the TCI state configuration for the SBFD time unit, which is only applied to the SBFD time unit. However, considering the flexibility of base station configuration, it may not be possible to restrict the corresponding data transmission through configuration; for example, PUSCH may only be transmitted in the SBFD time unit. The issue is similar for non-SBFD time units.

[0452] To address the aforementioned issues, one possible implementation is that the data transmission configuration corresponding to a specific time unit, such as the data transmission configuration for the SBFD time unit, is not limited to transmission only within the SBFD time unit. For example, if the data corresponding to the SBFD is transmitted in a non-SBFD time unit, the terminal can cancel the data transmission. Alternatively, if the data corresponding to the SBFD is transmitted in a non-SBFD time unit, the terminal cancels the data transmission in the current non-SBFD time unit and transmits the data in the next nearest SBFD time unit from the current time.

[0453] To address the aforementioned issues, one possible implementation is to configure data transmission for a specific time unit, such as a non-SBFD time unit, without limiting transmission to only non-SBFD time units. For example, if data corresponding to a non-SBFD time unit is transmitted in an SBFD time unit, the terminal can cancel the data transmission. Alternatively, if data corresponding to a non-SBFD time unit is transmitted in an SBFD time unit, the terminal cancels the data transmission in the current SBFD time unit and transmits the data in the next nearest non-SBFD time unit from the current time.

[0454] The main design scheme of this invention is to determine the configuration method of TCIstate of the terminal in the SBFD time unit and the non-SBFD time unit.

[0455] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions.

The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be hardware circuits designed for artificial intelligence, which can be understood as ASICs, such as Neural Network Processing Units (NPUs), Tensor Processing Units (TPUs), and Deep Learning Processing Units (DPUs).
