[0101] As shown in FIG. 1A, the communication system 100 includes a terminal 101 and a network device 102.

[0102] In some embodiments, the terminal 101 includes at least one of, for example, a mobile phone, a wearable device, an Internet of Things device, a communication-capable automobile, a smart automobile, a Pad, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, but is not limited thereto.

[0103] In some embodiments, the network device 102 includes at least one of, for example, an access network device, a core network device, but is not limited thereto.

[0104] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network, and the access network device can include at least one of an evolved NodeB (eNB) in a 5G communication system, a next generation eNB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, an access node in a Wi-Fi system, but is not limited thereto.

[0105] In some embodiments, the technical solutions of the present disclosure can be applied to an Open RAN architecture, at this time, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be realized through software or programs.

[0106] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), wherein the CU can also be referred to as a control unit. The CU-DU structure can split the protocol layers of the access network device, and part of the functions of the protocol layers are controlled by the CU, and the remaining part or all of the functions of the protocol layers are distributed in the DU and controlled by the CU, but the present disclosure is not limited thereto.

[0107] In some embodiments, the core network device can be one device including multiple network elements, etc., or can be multiple devices or device groups, each including all or part of the multiple network elements. The network element can be virtual or physical. The core network includes, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

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

[0109] In some embodiments, the network device can configure a downlink subband (DL subband) on an uplink (UL) time unit or a flexible time unit, and the terminal can receive downlink data on the DL subband. The time-frequency domain resources of the DL subband can be determined by explicit configuration.

[0110] For example, as shown in FIG. 1B, the downlink time unit or the flexible time unit configured with the uplink subband can be referred to as an SBFD time unit, such as slot#(n+1), slot#(n+2), and slot#(n+3). The uplink time unit that can only perform uplink transmission or the downlink time unit that can only perform downlink transmission is referred to as a non-SBFD time unit, such as slot#n, slot#(n+4), and slot#(n+5) in FIG. 1B.

[0111] On the SBFD time unit, the terminal can transmit uplink data on the UL subband. At this time, if there is another terminal, for example, a legacy terminal, receiving downlink data within the range of the downlink subband (DL subband), in order to reduce the interference on the reception of the downlink data, the terminal can adjust the transmission beam or the transmission power on the UL subband. On the non-SBFD time unit, all terminals in the cell transmit uplink data, and there is no problem of interference between terminals, thereby causing the terminal to adopt different uplink power control and / or uplink beam on the SBFD time unit and the non-SBFD time unit.

[0112] For the network device, on the SBFD time unit, the network device can need to simultaneously receive uplink data and transmit downlink data, and on the non-SBFD time unit, the network device only needs to receive uplink data or transmit downlink data. The network device can adopt different antenna configurations on the SBFD time unit and the non-SBFD time unit, thereby corresponding to different spatial relations, and also causing the network device to configure different power control parameters and / or spatial relations on the SBFD time unit and the non-SBFD time unit.

[0113] In related mechanisms, to achieve joint indication of uplink transmission and / or downlink transmission, and power control and / or spatial relation, a unified transmission configuration indicator (unified TCI) framework is introduced, and the terminal can determine the power control parameters and spatial relation corresponding to data transmission based on the TCI configuration.

[0114] In the SBFD scenario, the power control parameters corresponding to the uplink data transmitted by the terminal in the SBFD time unit and the non-SBFD time unit are also different for different spatial relations. If the unified TCI framework is introduced in the SBFD scenario, efficient indication of power control parameters and / or spatial relations can be achieved.

[0115] In the unified TCI framework, the terminal is configured with a TCI state (TCI-State) or an uplink TCI state (TCI-UL-State) based on a downlink or joint TCI state list (dl-OrJointTCI-StateList), and for a corresponding uplink channel or uplink signal, such as a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), and a sounding reference signal (SRS), or for other channels or signals, such as downlink channels or downlink signals, one or two TCI states are indicated, as follows:

[0116] The path loss reference signal (PL RS) q of the uplink channel or uplink signal, such as SRS (providing SRS following unified TCI state), PUSCH, PUCCH (or downlink channel or downlink signal, such as PDSCH, PDCCH, positioning reference signal PRS) d Determined based on the indicated TCI state (TCI-State) or TCI-UL-State;

[0117] If the uplink channel or uplink signal (or downlink channel or downlink signal) is configured based on the TCI-State or TCI-UL-State, the terminal determines the corresponding P0, Alpha, and l based on the indicated TCI-State or TCI-UL-State;

[0118] In some scenarios, the terminal determines the P0, Alpha and l corresponding to the uplink signal (e.g., SRS) based on the indicated TCI-State or TCI-UL-State.

[0119] wherein the P0 is the target received power, the Alpha is the path loss adjustment parameter, and the l is the closed loop power control index.

[0120] For non-DCI scheduled data transmission (e.g., PUCCH or PUSCH), based on the RRC parameter, e.g., TCI state application indication (applyIndicatedTCI-State) indicates at least one of the following three states, e.g., {first, second, both}, three states correspond to one of the following three states: the first TCI, the second TCI, and both TCIs applied to the data transmission. In the case where the RRC parameter indicates two TCIs (both), the two TCIs can be determined or indicated based on the same data TCI state.

[0121] For periodic SRS or semi-persistent SRS, which does not support dynamic TCI indication based on DCI, the TCI applied to the SRS is determined based on a predefined rule: based on the TCI state corresponding to the SRS resource with the smallest identifier in the corresponding SRS resource set.

[0122] To determine the corresponding TCI state parameters in the SBFD scenario, the present disclosure provides the following methods for determining the state, as well as terminals, network devices, systems, and storage media.

[0123] FIG. 2 is an interaction diagram of a method for determining a state according to an embodiment of the present disclosure. As shown in FIG. 2, the present embodiment relates to a method for determining a state, and the method comprises:

[0124] In step S2101, the terminal 101 determines the type of time unit corresponding to the data transmission.

[0125] In some embodiments, the data transmission includes but is not limited to at least one of the following: uplink transmission; downlink transmission.

[0126] In one example, the uplink transmission can include but is not limited to at least one of the following: PUSCH; PUCCH; SRS.

[0127] In one example, the downlink transmission can 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).

[0128] In some embodiments, the time unit types include, but are 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, which is not limited in the present disclosure.

[0129] The SBFD time unit refers to a downlink time unit or a flexible time unit configured with an uplink subband, such as slot#(n+1), slot#(n+2), and slot#(n+3) in FIG. 1B. Of course, the SBFD time unit can also refer to an uplink time unit or a flexible time unit configured with a downlink subband.

[0130] The non-SBFD time unit can be an uplink time unit or a downlink time unit that is not configured with an uplink subband or a downlink subband and can only perform uplink transmission or downlink transmission, such as slot#n, slot#(n+4), and slot#(n+5) in FIG. 1B.

[0131] In some embodiments, the time unit in the present disclosure can be in units of symbols, slots, sub-slots, frames, subframes, etc., which are not limited in the present disclosure.

[0132] One sub-slot can include k consecutive symbols belonging to the same slot. k is a positive integer.

[0133] In some embodiments, the terminal 101 can determine the time unit type corresponding to the data transmission in the following manner:

[0134] Case 1: The time unit of the data transmission occasion i includes only one type of time unit.

[0135] The data transmission occasion i can refer to any occasion of data transmission.

[0136] The data transmission occasion i can refer to the slot with an index of i in a frame with a system frame number (SFN). occupies L consecutive symbols in the slot, starting from symbol S. L is a positive integer. Wherein, the data is transmitted in the slot, starting from symbol S, and occupies L consecutive symbols, the data includes but is not limited to PUSCH, PUCCH, SRS, Physical Random Access Channel (PRACH).

[0137] In one example, the time occasion i of the data transmission only includes time units of the first type, and the number of time units of the first type can be one or more. Then, the terminal 101 can determine that the type of the time unit corresponding to the data transmission is the first type.

[0138] In one example, the time occasion i of the data transmission only includes time units of the second type, and the number of time units of the second type can be one or more. Then, the terminal 101 can determine that the type of the time unit corresponding to the data transmission is the second type.

[0139] Wherein, the time occasion i can include one or more time units:

[0140] Exemplarily, the terminal 101 can determine the time domain position of the time units of different types based on the configuration of the network device 102 and the corresponding rules.

[0141] If the terminal 101 performs data transmission on the SBFD time unit based on scheduling, the terminal 101 determines that the type of the time unit corresponding to the data transmission is SBFD. If the terminal 101 performs data transmission on the non-SBFD time unit based on scheduling, the terminal 101 determines that the type of the time unit corresponding to the data transmission is non-SBFD.

[0142] Taking the PUSCH scheduled by the DCI as an example, if the terminal 101 determines that the PUSCH is transmitted on time unit #1 based on the DCI scheduling information. Correspondingly, if the terminal determines that the time unit #1 is an SBFD time unit based on the configuration of the network device 102 and / or the pre-defined rules, the terminal determines that the PUSCH is transmitted on the SBFD time unit. Exemplarily, the transmission is in the UL subband frequency domain range corresponding to the time unit #1.

[0143] On the contrary, if the terminal 101 determines that the time unit #1 is a non-SBFD time unit based on the configuration of the network device 102 or the corresponding pre-defined rules, the terminal 101 determines that the PUSCH is transmitted on the non-SBFD time unit. Exemplarily, the transmission is in the UL BWP frequency domain range corresponding to the time unit #1.

[0144] The time units in the occasion i can include multiple time units of the same type.

[0145] If the terminal 101 performs data transmission on multiple consecutive SBFD time units based on scheduling, the terminal 101 determines that the time unit type corresponding to the data transmission is SBFD. If the terminal 101 performs data transmission on multiple non-SBFD time units based on scheduling, the terminal 101 determines that the time unit type corresponding to the data transmission is non-SBFD.

[0146] Case 2: The occasion i of the data transmission includes time units of two types.

[0147] In one example, the terminal 101 determines that the time unit type corresponding to the data transmission is the first type or the second type, i.e., SBFD or non-SBFD.

[0148] For example, the terminal 101 can determine the time unit type corresponding to the data transmission based on the type of the mth time unit in the occasion i of the data transmission.

[0149] Wherein, m can be a positive integer.

[0150] For example, m is 1, and the terminal 101 can determine the time unit type corresponding to the data transmission based on the type of the 1st time unit in the occasion i.

[0151] If the 1st time unit in the occasion i is an SBFD time unit, the time unit type corresponding to the data transmission is SBFD. If the 1st time unit in the occasion i is a non-SBFD time unit, the time unit type corresponding to the data transmission is non-SBFD.

[0152] For example, the terminal 101 can determine the time unit type corresponding to the data transmission based on the type of the time unit with a larger number in the occasion i of the data transmission.

[0153] For example, the occasion i includes 5 time units, of which 3 are SBFD time units and 2 are non-SBFD time units, and the terminal 101 determines that the time unit type corresponding to the data transmission is SBFD.

[0154] For example, the terminal 101 can determine the time unit type corresponding to the data transmission based on a predefined manner.

[0155] For example, in order to better utilize sub-band resources, the terminal 101 can directly determine that the time unit type corresponding to the data transmission is SBFD.

[0156] For another example, in order to reduce scheduling complexity of the network device and reduce inter-terminal interference, the terminal 101 can directly determine the time unit type corresponding to the data transmission as non-SBFD.

[0157] In one example, the time unit type corresponding to the data transmission is determined to include the first type and the second type, i.e., SBFD and non-SBFD.

[0158] The above is only an example, and the disclosure does not limit the scheme for determining the time unit type corresponding to the data transmission.

[0159] Step S2102, the network device 102 determines the time unit type corresponding to the data transmission.

[0160] In some embodiments, the network device 102 determines the time unit type corresponding to the data transmission in a similar manner to the terminal 101, which will not be described here.

[0161] Step S2103a, the network device 102 determines one or more TCI state lists.

[0162] In some embodiments, the network device 102 can determine the one or more TCI state lists based on a predefined manner.

[0163] In one example, the one or more TCI state lists can be agreed by a protocol. Each TCI state list can include one or more TCI states.

[0164] In one example, one TCI state list can be agreed by a protocol, and the TCI states in the TCI state list can be used for uplink transmission and downlink transmission.

[0165] In one example, multiple TCI state lists, such as 2 TCI state lists, can be agreed by a protocol, and the TCI states included in one list can be used for uplink transmission, and the TCI states included in the other list can be used for downlink transmission.

[0166] In one example, multiple TCI state lists, such as 4 TCI state lists, can be agreed by a protocol, and the TCI states included in 2 lists can be used for uplink transmission (corresponding to SBFD time units and non-SBFD time units, respectively), and the TCI states included in the other 2 lists can be used for downlink transmission (corresponding to SBFD time units and non-SBFD time units, respectively).

[0167] In one example, the number of TCI state lists can be more, and the disclosure does not limit this.

[0168] In some embodiments, the network device 102 can configure one or more TCI state lists.

[0169] The above is only an example, and the disclosure does not limit the manner in which the network device 102 determines the TCI state list.

[0170] Step S2103b, the network device 102 sends the second indication signaling to the terminal 101.

[0171] In some embodiments, the terminal 101 can receive the second indication signaling.

[0172] In some embodiments, the second indication signaling is used to indicate one or more TCI state lists configured by the network device 102. Each TCI state list can include one or more TCI states.

[0173] In some embodiments, the second indication signaling can be Radio Resource Control (RRC) signaling.

[0174] In one example, the second indication signaling can indicate one TCI state list, and the TCI states in the TCI state list can be used for uplink transmission and downlink transmission.

[0175] In one example, the second indication signaling can indicate multiple TCI state lists, for example, 2 TCI state lists, wherein the TCI states included in one list can be used for uplink transmission, and the TCI states included in the other list can be used for downlink transmission.

[0176] In one example, the second indication signaling can indicate multiple TCI state lists, for example, 4 TCI state lists, wherein the TCI states included in 2 lists can be used for uplink transmission (corresponding to SBFD time units and non-SBFD time units, respectively), and the TCI states included in the other 2 lists can be used for downlink transmission (corresponding to SBFD time units and non-SBFD time units, respectively).

[0177] In some embodiments, step S2103b is an optional execution step, for example, in the case where the network device 102 and the terminal 101 both determine one or more TCI state lists based on a predefined manner, step S2103b can not be executed.

[0178] In some embodiments, both step S2103a and step S2103b can be executed, for example, in the case where the network device 102 configures one or more TCI state lists and then informs the terminal through the second indication signaling, steps S2103a and S2103b can be executed.

[0179] Step S2104, the terminal 101 determines one or more TCI state lists.

[0180] In some embodiments, the terminal 101 determines the one or more TCI state lists based on a predefined manner.

[0181] In one example, one TCI state list can be agreed by protocol, and the TCI states in the TCI state list can be used for uplink transmission and downlink transmission.

[0182] In one example, multiple TCI state lists, e.g., 2 TCI state lists, can be agreed by protocol, wherein the TCI states included in one list can be used for uplink transmission, and the TCI states included in the other list can be used for downlink transmission.

[0183] In one example, multiple TCI state lists, e.g., 4 TCI state lists, can be agreed by protocol, wherein the TCI states included in 2 lists can be used for uplink transmission (corresponding to SBFD time unit and non-SBFD time unit respectively), and the TCI states included in the other 2 lists can be used for downlink transmission (corresponding to SBFD time unit and non-SBFD time unit respectively).

[0184] In some embodiments, the terminal 101 determines the one or more TCI state lists based on the second indication signaling sent by the network device 102.

[0185] In one example, the second indication signaling can indicate one TCI state list, and the TCI states in the TCI state list can be used for uplink transmission and downlink transmission.

[0186] In one example, the second indication signaling can indicate multiple TCI state lists, e.g., 2 TCI state lists, wherein the TCI states included in one list can be used for uplink transmission, and the TCI states included in the other list can be used for downlink transmission.

[0187] In one example, the second indication signaling can indicate multiple TCI state lists, e.g., 4 TCI state lists, wherein the TCI states included in 2 lists can be used for uplink transmission (corresponding to SBFD time unit and non-SBFD time unit respectively), and the TCI states included in the other 2 lists can be used for downlink transmission (corresponding to SBFD time unit and non-SBFD time unit respectively).

[0188] In some embodiments, the terminal 101 determines the one or more TCI state lists based on the predefined manner and the second indication signaling sent by the network device 102.

[0189] In one example, the terminal 101 determines one or more TCI state lists based on the protocol agreement, and determines one or more of the TCI state lists based on the second indication signaling.

[0190] In step S2105a, the network device 102 determines the TCI state corresponding to each type of time unit.

[0191] In some embodiments, the network device 102 can determine the TCI state corresponding to each type of time unit based on a predefined manner.

[0192] In one example, the TCI state determined here can refer to the activated TCI state corresponding to each type of time unit.

[0193] In some embodiments, the 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.

[0194] In one example, n is a positive integer.

[0195] For example, the network device 102 can determine the TCI state corresponding to the SBFD time unit and the non-SBFD time unit based on 1, for example the 1st, TCI state in each TCI state list.

[0196] Assuming the number of TCI state lists is 1, the network device 102 determines the 1st TCI state in the TCI state list as the activated TCI state corresponding to the SBFD time unit and the non-SBFD time unit.

[0197] Assuming the number of TCI state lists is 2, each TCI state list corresponds to a transmission direction, for example, TCI state list #1 corresponds to uplink transmission, and TCI state list #2 corresponds to downlink transmission, the network device 102 determines the 1st TCI state in the TCI state list #1 corresponding to the uplink transmission as the activated uplink TCI state corresponding to the SBFD time unit and the non-SBFD time unit. The 1st TCI state in the TCI state list #2 corresponding to the downlink transmission is determined as the activated downlink TCI state corresponding to the SBFD time unit and the non-SBFD time unit.

[0198] It can be understood that one of the two TCI state lists can correspond to TRP #1, and the other one can correspond to TRP #2. The TCI states in each TCI state list can be applicable to uplink transmission and downlink transmission. At this time, the first TCI state in the TCI state list corresponding to TRP #1 can be used as the TCI state corresponding to the SBFD time unit and the non-SBFD time unit. The first TCI state in the TCI state list corresponding to TRP #2 can be used as the TCI state corresponding to the SBFD time unit and the non-SBFD time unit.

[0199] It is assumed that the number of TCI state lists is 4, of which two TCI state lists can correspond to uplink transmission, and the other two TCI state lists can correspond to downlink transmission. The network device 102 determines the available uplink TCI states corresponding to SBFD and non-SBFD, respectively, from the first TCI state in the two TCI state lists corresponding to uplink transmission. The first TCI state in the two TCI state lists corresponding to downlink transmission is used to determine the available downlink TCI states corresponding to SBFD and non-SBFD, respectively.

[0200] It can be understood that two of the four TCI state lists can correspond to TRP #1, and the other two can correspond to TRP #2. The TCI states in each TCI state list can be applicable to uplink transmission and downlink transmission. At this time, the first TCI state in one of the TCI state lists corresponding to TRP #1 (or TRP #2) can be used as the TCI state corresponding to the SBFD time unit. The first TCI state in the other one of the TCI state lists corresponding to TRP #1 (or TRP #2) can be used as the TCI state corresponding to the non-SBFD time unit.

[0201] The number of TCI state lists can also be more, which is not limited in the present disclosure.

[0202] In step S2105b, the network device 102 sends the first indication signaling to the terminal 101.

[0203] In some embodiments, the terminal 101 receives the first indication signaling.

[0204] In some embodiments, the first indication signaling is used to indicate the TCI state corresponding to each type of time unit.

[0205] In some embodiments, the first indication signaling can be any one of the following: RRC signaling; MAC CE; and DCI.

[0206] In some embodiments, the data transmission corresponds to a same transmission configuration on multiple types of time units, e.g., the SBFD time units and the non-SBFD time units correspond to a same transmission configuration, where the transmission configuration can include but is not limited to a list of TCI states or a TCI configuration for a specific uplink data transmission or a specific downlink data transmission.

[0207] wherein the data transmission configuration can be a ConfigGrant-config, a PUCCH configuration, a PUSCH configuration, etc.

[0208] Correspondingly, the first indication signaling can be used to indicate at least one of the following:

[0209] The first type of time units and the second type of time units apply a same TCI state.

[0210] The first type of time units and the second type of time units apply different TCI states.

[0211] In one example, the first indication signaling can be used to indicate that the SBFD time units and the non-SBFD time units apply a same TCI state.

[0212] In one example, the first indication signaling can be used to indicate that the SBFD time units and the non-SBFD time units apply different TCI states respectively.

[0213] Exemplarily, the first indication signaling can indicate a number of TCI states corresponding to each type of time units, e.g., one type of time units can correspond to 1 TCI state, or one type of time units can correspond to two or more TCI states. For example, the SBFD time units can correspond to 1 TCI state, and the non-SBFD time units can correspond to 2 TCI states.

[0214] In one example, the network device 102 can determine the TCI states applied on each type of time units in the case that the first indication signaling is used to indicate that the SBFD time units and the non-SBFD time units apply different TCI states respectively.

[0215] Exemplarily, a same TCI state (or a same group of TCI states) can be applied to the SBFD time units and the non-SBFD time units.

[0216] Exemplarily, a same TCI state (or a same group of TCI states) can be applied to the SBFD time units, and the non-SBFD time units can be ignored.

[0217] Exemplarily, one TCI state (or one group of TCI states) can be applied to the non-SBFD time unit, and the SBFD time unit can be ignored.

[0218] Exemplarily, among 2 TCI states (or 2 groups of TCI states), the first TCI state (or the first group of TCI states) can be applied to the SBFD time unit, and the second TCI state (or the second group of TCI states) can be applied to the non-SBFD time unit.

[0219] Exemplarily, among 2 TCI states (or 2 groups of TCI states), the first TCI state (or the first group of TCI states) can be applied to the SBFD time unit, and the second TCI state (or the second group of TCI states) can be applied to the non-SBFD time unit.

[0220] Exemplarily, the 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.

[0221] Exemplarily, the index of the first TCI state can be greater than the index of the second TCI state.

[0222] Exemplarily, the index of the first TCI state can be less than the index of the second TCI state.

[0223] Exemplarily, 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.

[0224] Exemplarily, 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.

[0225] Exemplarily, 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.

[0226] Exemplarily, 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.

[0227] Exemplarily, 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.

[0228] Exemplarily, the position index corresponding to the first TCI state, the position index corresponding to the second TCI state can be determined based on MAC CE or RRC signaling.

[0229] In one example, the first indication signaling can be used to indicate the case that different TCI states (or different groups of TCI states) are applied in the SBFD time units and the non-SBFD time units respectively. The network device 102 can indicate the TCI state corresponding to each type of time unit through the first indication signaling.

[0230] For example, TCI state #1 is applied in the SBFD time units, and TCI state #2 is applied in the non-SBFD time units.

[0231] In some embodiments, the data transmission corresponds to different transmission configurations in different types of time units, where the transmission configuration can include but is not limited to a TCI state list or a TCI configuration for a specific uplink data transmission or a specific downlink data transmission.

[0232] For example, the SBFD time units and the non-SBFD time units correspond to different transmission configurations, where the transmission configuration can include but is not limited to a TCI state list or a TCI configuration for a specific uplink data transmission or a specific downlink data transmission.

[0233] In one example, the network device 102 can indicate the different transmission configurations corresponding to each type of time unit through the first indication signaling, for example, TCI state list #1 corresponding to the SBFD time units, and TCI state list #2 corresponding to the non-SBFD time units.

[0234] In one example, the network device 102 can determine that the transmission configuration corresponding to each type of time unit can only be applied in the time unit of the type.

[0235] Exemplarily, the TCI state in the TCI state list #1 corresponding to the SBFD time units is only applied in the SBFD time units.

[0236] Exemplarily, the TCI state in the TCI state list #2 corresponding to the non-SBFD time units is only applied in the non-SBFD time units.

[0237] In some embodiments, the 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, in the case that the network device 102 and the terminal 101 determine the TCI state corresponding to each type of time unit based on a predefined manner, step S2105b can not be executed.

[0238] In some embodiments, both step S2105a and step S2105b can be performed, for example, in the case that the network device 102 configures the possible TCI states corresponding to each type of time unit through the first indication information to inform the terminal.

[0239] Step S2106, the terminal 101 determines the TCI state corresponding to each type of time unit.

[0240] In some embodiments, the TCI state determined here can refer to the activated TCI state of each type of time unit.

[0241] In some embodiments, the terminal 101 can determine the activated TCI state of each type of time unit based on a predefined manner.

[0242] In one example, the terminal 101 can determine the activated TCI state corresponding to each type of time unit based on n TCI states in each TCI state list. Wherein n is a positive integer.

[0243] For example, the terminal 101 can determine the available TCI state corresponding to the SBFD time unit and the non-SBFD time unit based on 1, for example, the first TCI state in each TCI state list.

[0244] Assuming the number of TCI state lists is 1, the terminal 101 can determine the first TCI state in the TCI state list as the activated TCI state corresponding to the SBFD time unit and the non-SBFD time unit.

[0245] Assuming the number of TCI state lists is 2, the terminal 101 can determine the first TCI state in the TCI state list corresponding to the uplink transmission as the activated uplink TCI state corresponding to the SBFD time unit and the non-SBFD time unit. The first TCI state in the TCI state list corresponding to the downlink transmission is determined as the activated downlink TCI state corresponding to the SBFD time unit and the non-SBFD time unit.

[0246] Assuming the number of TCI state lists is 4, the terminal 101 determines the first TCI state in the two TCI state lists corresponding to the uplink transmission as the activated uplink TCI state corresponding to the SBFD and the non-SBFD, respectively. The first TCI state in the two TCI state lists corresponding to the downlink transmission is determined as the activated downlink TCI state corresponding to the SBFD and the non-SBFD, respectively.

[0247] The above is only an example description, and the terminal 101 can also determine the TCI states corresponding to different types of time units based on the mTRP scenario.

[0248] In some embodiments, the terminal 101 can determine the TCI state of each type of time unit based on the first indication signaling sent by the network device 102.

[0249] In one example, the data transmission corresponds to the same transmission configuration on multiple types of time units, for example, the SBFD time unit and the non-SBFD time unit correspond to the same transmission configuration, wherein the transmission configuration can include but is not limited to a TCI state list or a TCI configuration for a specific uplink data transmission or a specific downlink data transmission.

[0250] The first indication signaling is used to indicate that the first type of time unit and the second type of time unit apply the same TCI state, or the first type of time unit and the second type of time unit respectively apply different TCI states.

[0251] For example, in the case that 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 manner or the first indication signaling sent by the network device 102.

[0252] For example, the terminal 101 can determine the first TCI state in the TCI list #1 (corresponding to both the SBFD time unit and the non-SBFD time unit) as the TCI state applied on the SBFD time unit and the non-SBFD time unit based on the predefined manner.

[0253] For another example, the terminal 101 can determine the TCI state applied on the SBFD time unit and the non-SBFD time unit respectively based on the display signaling sent by the network device 102, such as the first indication signaling. For example, the first indication signaling indicates that the TCI state applied on the SBFD time unit and the non-SBFD time unit is TCI state #2 in the TCI state list.

[0254] For example, in the case that the first type of time unit and the second type of time unit apply different TCI states, the terminal 101 can determine the TCI state respectively applied on the SBFD time unit and the non-SBFD time unit based on a predefined manner or the indication signaling sent by the network device 102.

[0255] Exemplarily, the first indication signaling or a separate third indication signaling can indicate that one or more TCI states are applied on the SBFD time unit, and different one or more TCI states can be applied on the non-SBFD time unit. For example, TCI state #1 is applied on the SBFD time unit, and TCI state #2 can be applied on the non-SBFD time unit.

[0256] Exemplarily, the 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.

[0257] Exemplarily, the index of the first TCI state can be greater than the index of the second TCI state.

[0258] Exemplarily, the index of the first TCI state can be less than the index of the second TCI state.

[0259] Exemplarily, the index of the first TCI state can be greater than the index of the second TCI state.

[0260] Exemplarily, 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.

[0261] Exemplarily, 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.

[0262] Exemplarily, 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.

[0263] Exemplarily, 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. Exemplarily, 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.

[0264] Exemplarily, the position index corresponding to the first TCI state and the position index corresponding to the second TCI state can be determined based on MAC CE or RRC signaling.

[0265] In one example, the first indication signaling can be used to indicate the case that different TCI states are applied on SBFD time units and non-SBFD time units respectively, and the network device 102 can inform the terminal 101 of the TCI states applied on each type of time unit through the first indication signaling.

[0266] In some embodiments, different transmission configurations correspond to different types of time units, for example, SBFD time units and non-SBFD time units correspond to different transmission configurations, wherein the transmission configurations can include but are not limited to a TCI state list or a TCI configuration for a specific uplink data transmission or a specific downlink data transmission.

[0267] In one example, the terminal 101 can determine the TCI states corresponding to SBFD time units and non-SBFD time units respectively in different TCI state lists.

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

[0269] In one example, the terminal 101 can determine the downlink TCI state corresponding to the SBFD time unit in the TCI configuration corresponding to the downlink transmission of the SBFD time unit type, and determine the downlink TCI state corresponding to the non-SBFD time unit in the TCI configuration corresponding to the downlink transmission of the non-SBFD time unit type.

[0270] In one example, the terminal 101 can determine that the transmission configuration corresponding to each type of time unit can only be applied on the type of time unit.

[0271] For example, the TCI states in the TCI state list #1 corresponding to the SBFD time unit are only applied on the SBFD time unit.

[0272] For example, the TCI states in the TCI state list #2 corresponding to the non-SBFD time unit are only applied on the non-SBFD time unit.

[0273] In some embodiments, the terminal 101 can determine the available or possible TCI states of each type of time unit based on a predefined manner and the first indication signaling sent by the network device 102.

[0274] The above is merely an example, and the disclosure does not limit the process in which the terminal 101 determines the TCI state available or possible for each type of time unit.

[0275] In step S2107, the terminal 101 determines the TCI state corresponding to the data transmission.

[0276] In some embodiments, the terminal 101 can determine the actual TCI state corresponding to the data transmission based on the type of time unit corresponding to the data transmission and the TCI state corresponding to the type of time unit.

[0277] 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, and the number of specific TCI states is not limited by the disclosure.

[0278] In some embodiments, the type of time unit corresponding to the data transmission is SBFD, 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, and the terminal 101 can determine that the TCI state corresponding to the data transmission is TCI state #1.

[0279] In some embodiments, the type of time unit corresponding to the data transmission is non-SBFD, 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, and the terminal 101 can determine that the TCI state corresponding to the data transmission is TCI state #1.

[0280] In some embodiments, the type of time unit corresponding to the data transmission is SBFD, the 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, and the terminal 101 can determine that the TCI state corresponding to the data transmission is TCI state #1.

[0281] In some embodiments, the type of time unit corresponding to the data transmission is non-SBFD, the 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, and the terminal 101 can determine that the TCI state corresponding to the data transmission is TCI state #2.

[0282] In some embodiments, the time unit types corresponding to the data transmission include a first type and a second type, the data transmission corresponds to a same transmission configuration on the time units of the multiple types, specifically, the SBFD time units and the non-SBFD time units correspond to TCI state #1, and the terminal 101 can determine that the TCI state corresponding to the data transmission is TCI state #1.

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

[0284] In some embodiments, the time unit types corresponding to the data transmission include a first type and a second type, the data transmission corresponds to different transmission configurations on the time units of the multiple types, specifically, the SBFD time units and the non-SBFD time units correspond to TCI state #1 and TCI state #2 respectively, and at this time, the terminal 101 can determine that the TCI state corresponding to the data transmission is irrelevant to the time unit corresponding to the data transmission.

[0285] In some embodiments, the time unit types corresponding to the data transmission include a first type and a second type, the data transmission corresponds to different transmission configurations on the time units of the multiple types, specifically, the SBFD time units and the non-SBFD time units correspond to TCI state #1 and TCI state #2 respectively, and at this time, the terminal 101 can determine that the TCI state corresponding to the data transmission is irrelevant to the time unit corresponding to the data transmission.

[0286] In one example, the terminal 101 can fall back to a traditional mechanism to determine the second TCI state.

[0287] For example, the terminal 101 can determine the TCI state corresponding to the data transmission according to a related mechanism, such as a TCI state (TCI-State) configured based on a downlink or joint TCI state list (dl-OrJointTCI-StateList) or an uplink TCI state (TCI-UL-State).

[0288] Step S2108, the network device 102 determines the TCI state corresponding to the data transmission.

[0289] 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 foregoing step S2109, which will not be described here.

[0290] Step S2109, the terminal 101 performs data transmission processing.

[0291] In some embodiments, the terminal 101 performs uplink data transmission processing.

[0292] In some embodiments, data transmission corresponds to different transmission configurations on different types of time units, and the transmission configuration corresponding to a type of time unit is only applied to the type of time unit. Considering the flexibility of configuration, it may not be possible to restrict data transmission to be transmitted only on a certain type of time unit by configuration, for example, it is not possible to restrict PUSCH to be transmitted only on SBFD or non-SBFD time units. At this time, the terminal 101 can use the following data transmission processing for processing:

[0293] Method 1, if the data of a type of time unit needs to be transmitted on another type of time unit based on the configuration, the terminal 101 can cancel the data transmission.

[0294] For example, the transmission configuration is a first transmission configuration, the first transmission configuration is a transmission configuration corresponding to a first type of time unit, and the data transmission corresponds to a second type of time unit, for example, the data transmission corresponds to a second type of time unit, or a first type and a second type, at this time, the terminal 101 can cancel the data transmission.

[0295] For example, the transmission configuration is a second transmission configuration, the second transmission configuration is a transmission configuration corresponding to a second type of time unit, and the data transmission corresponds to a first type of time unit, for example, the data transmission corresponds to a first type of time unit, or a first type and a second type, at this time, the terminal 101 can cancel the data transmission.

[0296] For example, the data transmission configuration corresponding to a specific time unit, for example, the data transmission configuration of the non-SBFD time unit is transmitted on the SBFD time unit, and the terminal can cancel the data transmission.

[0297] For example, if the data transmission configuration of the SBFD time unit is transmitted on the non-SBFD time unit, the terminal cancels the data transmission.

[0298] Method 2, the terminal 101 can only perform data transmission on the type of time unit.

[0299] For example, the transmission configuration is a first transmission configuration, the first transmission configuration is a transmission configuration corresponding to a first type of time unit, and the data transmission corresponds to a second type of time unit, skip the time unit of the second type, and perform data transmission on the subsequent first type of time unit, for example, perform data transmission on the next first type of time unit.

[0300] For example, the transmission configuration is a second transmission configuration, the second transmission configuration 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 time unit of the first type is skipped, and the data transmission is performed on a subsequent time unit of the second type, for example, on a next time unit of the second type.

[0301] For example, the data transmission configuration corresponding to a specific time unit, for example, data corresponding to a non-SBFD time unit is transmitted on an SBFD time unit, and the terminal can cancel the data transmission on the SBFD time unit and perform the data transmission on a next non-SBFD time unit.

[0302] For example, the data transmission configuration corresponding to a specific time unit, for example, data corresponding to an SBFD time unit is transmitted on a non-SBFD time unit, and the terminal can cancel the data transmission on the non-SBFD time unit and perform the data transmission on a next SBFD time unit.

[0303] The above is only an example, and the disclosure does not limit the specific data transmission processing mode.

[0304] In step S2110, the network device 102 performs data transmission processing.

[0305] In some embodiments, the network device 102 performs downlink data transmission processing.

[0306] In some embodiments, if data of a certain type of time unit needs to be transmitted on another type of time unit based on the configuration, the network device 102 cancels the downlink data transmission. Or only perform data transmission on a type of time unit. The specific implementation process is similar to step S2110, which will not be repeated here.

[0397] In the above embodiments, the TCI state corresponding to the data transmission can be determined in the case that the data transmission corresponds to the same or different transmission configuration on multiple types of time units, thereby improving the availability of SBFD.

[0398] The above process is further illustrated as follows.

[0399] In the embodiments of the present disclosure, the static configuration of the TCI parameters based on different time domain unit types can be implemented in the SBFD scenario.

[0400] On the terminal side:

[0401] The terminal 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 of the data transmission, and determines the TCI state of the data transmission on the SBFD time unit and the non-SBFD time unit based on at least one of the following manners:

[0402] Method 1: The terminal determines at least one TCI state corresponding to the data transmission based on a predefined rule:

[0403] The terminal determines the at least one TCI state based on the first N TCI states of the configured TCI state set or list.

[0404] Method 2: The terminal determines at least one TCI state corresponding to the data transmission based on indication signaling,

[0405] Example 1: The data transmission corresponding to the SBFD time unit and the non-SBFD time unit is determined based on the same data transmission configuration:

[0406] For example, the data transmission configuration can be a ConfigGrant-config (CG-config), a PUCCH configuration, etc.

[0407] The indication signaling indicates at least one of the following:

[0408] The same TCI state applied by the SBFD time unit and the non-SBFD time unit;

[0409] Different TCI states respectively applied by the SBFD time unit and the non-SBFD time unit;

[0410] Example 2: The data transmission corresponding to the SBFD time unit and the non-SBFD time unit is determined based on different data transmission configurations:

[0411] If the data of the SBFD (non-SBFD) time unit is transmitted based on the configuration on the non-SBFD (SBFD) time unit,

[0412] The terminal cancels the data transmission;

[0413] And / or, the terminal transmits the data on the next SBFD (non-SBFD) time unit.

[0414] On the base station side:

[0415] The base station determines the time unit type (for example, SBFD time unit or non-SBFD time unit) corresponding to the data transmission based on the resource type of the data transmission, and sends indication signaling indicating the TCI state of the data transmission on the SBFD time unit and the non-SBFD time unit.

[0416] Method 1: The base station indicates the data corresponding to the SBFD time unit and the non-SBFD time unit based on the same data transmission configuration:

[0417] The indication signaling indicates at least one of:

[0418] The same TCI state applied by the SBFD time unit and the non-SBFD time unit;

[0419] Different TCI states respectively applied by the SBFD time unit and the non-SBFD time unit;

[0420] Method 2: The base station indicates the data corresponding to the SBFD time unit and the non-SBFD time unit based on different data transmission configurations:

[0421] If the data of the SBFD (non-SBFD) time unit is transmitted based on the configuration on the non-SBFD (SBFD) time unit, the base station determines:

[0422] The terminal cancels the data transmission;

[0423] And / or, the terminal transmits the data on the next SBFD (non-SBFD) time unit.

[0424] The following will elaborate the specific embodiments of the application from the perspective of the terminal:

[0425] Embodiment:

[0426] Assuming that the terminal is a terminal supporting the SBFD feature, 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.

[0427] In another possible implementation, a terminal supporting the SBFD feature can receive downlink data on a DL subband and / or transmit uplink data on a UL subband based on a base station configuration on the UL or flexible symbol.

[0428] As described above, a terminal can determine the time-domain location of an SBFD time unit based on a base station configuration and corresponding rules. If the terminal transmits data on an SBFD time unit based on scheduling, the terminal determines that the data transmission corresponds to an 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 the DCI scheduling information, the terminal determines that the PUSCH is transmitted on an SBFD time unit if the terminal determines that the time unit n corresponds to an SBFD time unit based on a base station configuration and corresponding rules. For example, the time unit n corresponds to transmission in the frequency-domain range of an UL subband. In contrast, if the terminal determines that the time unit is a non-SBFD time unit based on a base station configuration or corresponding predefined rules, the terminal determines that the PUSCH is transmitted on a non-SBFD time unit. For example, the time unit n corresponds to transmission in the frequency-domain range of an UL BWP.

[0429] Corresponding to uplink data on a transmission occasion i, if the occasion i contains both an SBFD time unit and a non-SBFD time unit, the terminal determines the type of time unit corresponding to the occasion i based on at least one of the following manners:

[0430] The terminal determines that the occasion i corresponds to an SBFD time unit, or the terminal determines that the occasion i corresponds to a non-SBFD time unit.

[0431] The terminal determines the type of time unit corresponding to the occasion i based on a first time unit corresponding to the occasion i. For example, if the first time unit is an SBFD time unit, the terminal determines that the type of time unit corresponding to the occasion i is an SBFD time unit, or if the first time unit is a non-SBFD time unit, the terminal determines that the type of time unit corresponding to the occasion i is a non-SBFD time unit.

[0432] The terminal determines that the occasion i corresponds to both an SBFD time unit and a non-SBFD time unit.

[0433] Or, if the occasion i contains both SBFD time units and non-SBFD time units, the terminal performs unified power control mechanism for different time unit types. For example, the existing mechanism is used to determine the corresponding power control parameters.

[0434] As described above, in the SBFD scenario, the embodiment of the present application determines the TCI state of the corresponding data transmission on the SBFD time unit and the non-SBFD time unit based on the pre-defined or signaling indication method.

[0435] The data transmission includes but is not limited to at least one of the following:

[0436] The uplink transmission includes but is not limited to PUSCH, SRS, PUCCH, etc.

[0437] The downlink transmission includes but is not limited to PDCCH, PDSCH, CSI-RS, SSB, etc.

[0438] In the following, the present application is based on different embodiments to take the transmission parameter corresponding to the power control and the spatial relationship TCI state as an example to describe the specific scheme of the present application, which is used for the terminal to determine the TCI state of the corresponding data transmission on the SBFD time unit and / or the non-SBFD time unit.

[0439] Embodiment:

[0440] As described above, the terminal determines at least one TCI state corresponding to the data transmission based on the pre-defined rule or the signaling indication method.

[0441] For example, the terminal determines one or more TCI state lists based on the pre-defined or signaling configuration method. For example, the terminal determines one TCI state list, and the TCI state can be applied to uplink and downlink at the same time. For example, the terminal determines two TCI state lists, and the two TCI state lists correspond to uplink and downlink respectively.

[0442] Embodiment 1:

[0443] Corresponding to the TCI state list, the terminal determines the first N TCI states in the one or more TCI lists as the TCI states corresponding to the data transmission; for example, in the case of one TCI state list, the terminal determines the N TCI states in the TCI state list as the TCI states that the data transmission can correspond to. For example, in the case of two TCI state lists, the terminal determines the first N TCI states in the two TCI state lists as the TCI states that the data transmission can correspond to.

[0444] Embodiment 2

[0445] In a possible implementation, the terminal determines the TCI states on the SBFD time unit and the non-SBFD time unit respectively based on the same data transmission configuration, which can be applied to the SBFD time unit and the non-SBFD time unit. For example, the data transmission configuration can be a TCI state list or a TCI configuration for a specific data transmission, which is not limited in the application.

[0446] The terminal determines the TCI states applied on the SBFD time unit and the non-SBFD time unit based on the configuration signaling. For example, the terminal receives indication signaling, which indicates at least one of the following:

[0447] The same TCI state is applied on the SBFD time unit and the non-SBFD time unit;

[0448] The SBFD time unit and the non-SBFD time unit apply different TCI states respectively;

[0449] In the case that the SBFD time unit and the non-SBFD time unit apply different TCI states respectively, the terminal determines the TCI state corresponding to the data transmission on the SBFD time unit / non-SBFD time unit based on a pre-defined or signaling-indicated manner, which is not described herein.

[0450] Embodiment 3

[0451] In a possible implementation, the terminal determines the TCI states on the SBFD time unit and the non-SBFD time unit respectively based on different data transmission configurations. For example, different TCI state lists are configured based on different time unit types, or different TCI states are configured based on different time unit types, which is not limited in the application.

[0452] In a possible implementation, a data transmission configuration corresponding to a specific time unit, for example, a TCI state configuration of an SBFD time unit, is only applied to the SBFD time unit. However, considering the flexibility of base station configuration, it can be impossible to limit the corresponding data transmission by configuration, for example, PUSCH is only transmitted in the SBFD time unit. The non-SBFD time unit problem is similar.

[0453] To solve the above problem, in a possible implementation, a data transmission configuration corresponding to a specific time unit, for example, a data transmission configuration of an SBFD time unit, is not limited to transmission in the SBFD time unit. For example, if SBFD corresponding data is transmitted in a non-SBFD time unit, the terminal can cancel the data transmission. For example, if non-SBFD corresponding data 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 nearest SBFD time unit from the current time.

[0454] To solve the above problem, in a possible implementation, a data transmission configuration corresponding to a specific time unit, for example, a data transmission configuration of an SBFD time unit, is not limited to transmission in the SBFD time unit. For example, if SBFD corresponding data is transmitted in a non-SBFD time unit, the terminal can cancel the data transmission. For example, if non-SBFD corresponding data 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 nearest SBFD time unit from the current time.

[0455] The main design scheme of the embodiment of the application is to determine the configuration mode of the TCI state of the terminal in the SBFD time unit and the non-SBFD time unit.

[0456] In the embodiments of the present disclosure, part or all of the steps, and optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or can be combined with optional implementation manners of other embodiments.
