[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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 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).

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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:

[0124] The path loss reference signal (PL RS) 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), is determined based on the indicated TCI state (TCI-State) or TCI-UL-State;

[0125] 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;

[0126] In some scenarios, a terminal determines P0, Alpha and l corresponding to an uplink signal such as SRS based on an indicated TCI-State or TCI-UL-State.

[0127] wherein P0 is a target received power, Alpha is a path loss adjustment parameter, and l is a closed loop index. With the introduction of the unified TCI mechanism, the TCI-state is introduced to the uplink power enhancement of a single-Transmit Receive Point (sTRP). Further, the TCI-state can be introduced to the uplink power enhancement of a multi-Transmit Receive Point (mTRP). The basic idea can be to achieve the indication of uplink power based on the TCI state, which specifically includes (taking mTRP as an example):

[0128] In a joint TCI state type, a TCI field in a downlink control information (DCI) indicates a TCI combination (e.g., DCI format formet1_1, 1_2 or 1_3) based on a downlink control information (DCI), which can include at most 2 TCI-states. The 2 TCI-states are applied to UL and DL power control (e.g., dl-OrJointTCI-StateList) at the same time. The combination is indicated based on a medium access control-control element (MAC CE). The specific MAC CE structure can be shown in FIG. 1C.

[0129] wherein F i，j The field can indicate whether the jth joint TCI state exists in the TCI state identification field associated with the code point i of the DCI transmission configuration indication field, where j = 1 or 2. If F i，j If the F i，j If the F

[0130] In separate TCI state type, the DCI-based TCI field indicates one TCI combination (DCI format 1_1, 1_2 or 1_3) which includes up to 4 TCI-states, 2 of which are applied to UL (e.g., uplink TCI addition modification list ul-TCI-toaddModList) and 2 to DL power control (e.g., dl-OrJointTCI-StateList), the combination can be indicated based on MAC CE, e.g., as shown in FIG. 1D.

[0131] wherein F i，j The field can indicate whether the jthDLTCIstate is present in the TCI state identification field associated with the codepoint i of the DCI transmission configuration indication field, where j = 1, 2. If F i，j If the field is set to 1, it indicates that the jthDLTCIstate of the codepoint i is present. If F i，j If the field is set to 0, it indicates that the jthDLTCIstate of the codepoint i is not present.

[0132] wherein S i，j The field can indicate whether the jthULTCIstate is present in the TCI state identification field associated with the codepoint i of the DCI transmission configuration indication field, where j = 1, 2. If S i，j If the field is set to 1, it indicates that the jthULTCIstate of the codepoint i is present. If S i，j If the field is set to 0, it indicates that the jthULTCIstate of the codepoint i is not present.

[0133] Based on the 2 TCI states indicated for UL, for the DCI scheduled UL transmission, one of single TCI or multi-TCI can be indicated based on the TCI selection field of the DCI format 1_1 or 1_2, e.g., as shown in Table 1.

[0134] Table 1

[0135] Wherein the one TCI combination indicated by the TCI selection field of the DCI in Table 1 is applied not only to the PDSCH scheduled by the DCI, but also to the PDSCH of the subsequent transmission and the UL signal until a new DCI is received to update the corresponding TCI state.

[0136] To determine the corresponding TCI state parameters in the SBFD scenario, the disclosure provides the following state determination method and terminal, network device, system and storage medium.

[0137] FIG. 2 is an interaction schematic diagram of the state determination method according to an embodiment of the disclosure. As shown in FIG. 2, the embodiment of the disclosure relates to a state determination method, and the above method comprises:

[0138] In step S2101, the terminal 101 determines a time unit type corresponding to data transmission.

[0139] In some embodiments, the data transmission includes but is not limited to at least one of the following: uplink transmission; downlink transmission.

[0140] In one example, the uplink transmission can include but is not limited to at least one of the following: PUSCH; PUCCH; SRS.

[0141] 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).

[0142] 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, which is not limited in the disclosure.

[0143] 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.

[0144] The non-SBFD time unit can be an uplink time unit or a downlink time unit that cannot be configured with an uplink subband or a downlink subband, can only perform uplink transmission, or can only perform downlink transmission, such as slot#n, slot#(n+4), and slot#(n+5) in FIG. 1B.

[0145] In some embodiments, the time unit in the disclosure can be in units of symbols, slots, sub-slots, frames, subframes, etc., which are not limited in the disclosure.

[0146] wherein one sub-slot can include k consecutive symbols belonging to the same slot or different slots. k is a positive integer.

[0147] In some embodiments, the terminal 101 can determine the time unit type corresponding to the data transmission in the following ways:

[0148] Case 1: the time occasion i of the data transmission only includes one type of time unit.

[0149] wherein the time occasion i of the data transmission can refer to any time occasion of the data transmission.

[0150] wherein the time occasion i of the data transmission can refer to the slot indexed as in a frame with a system frame number (SFN) from symbol S of the slot, occupying L consecutive symbols. L is a positive integer. Wherein the data is transmitted from symbol S in the slot, occupying L consecutive symbols, the data includes but is not limited to PUSCH, PUCCH, SRS, Physical Random Access Channel (PRACH).

[0151] In one example, the time occasion i of the data transmission only includes the first type of time unit, and the number of the first type of time unit can be one or more, then the terminal 101 can determine the time unit type corresponding to the data transmission as the first type.

[0152] In one example, the time occasion i of the data transmission only includes 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 the time unit type corresponding to the data transmission as the second type.

[0153] wherein the time occasion i can include one or more time units:

[0154] Exemplarily, the terminal 101 can determine the time domain location of different types of time units based on the configuration of the network device 102 and the corresponding rules.

[0155] If the terminal 101 performs data transmission on the SBFD time unit based on scheduling, the terminal 101 determines the time unit type corresponding to the data transmission as SBFD. If the terminal 101 performs data transmission on the non-SBFD time unit based on scheduling, the terminal 101 determines the time unit type corresponding to the data transmission as non-SBFD.

[0156] For example, if the terminal 101 determines, based on the DCI scheduling information, that the PUSCH is scheduled to be transmitted in time unit #1, the terminal determines that the PUSCH is transmitted in an SBFD time unit if the terminal determines, based on the configuration of the network device 102 and / or a predefined rule, that the time unit #1 is an SBFD time unit. For example, the PUSCH is transmitted in the time unit #1 in the UL subband frequency domain range.

[0157] In contrast, if the terminal 101 determines, based on the configuration of the network device 102 or the corresponding predefined rule, that the time unit #1 is a non-SBFD time unit, the terminal 101 determines that the PUSCH is transmitted in a non-SBFD time unit. For example, the PUSCH is transmitted in the time unit #1 in the UL BWP frequency domain range.

[0158] In one example, the time unit in the occasion i can include multiple time units of the same type.

[0159] If the terminal 101 is scheduled to perform data transmission in multiple consecutive SBFD time units, the terminal 101 determines that the time unit type corresponding to the data transmission is SBFD. If the terminal 101 is scheduled to perform data transmission in multiple non-SBFD time units, the terminal 101 determines that the time unit type corresponding to the data transmission is non-SBFD.

[0160] Case 2: The occasion i of the data transmission includes two types of time units.

[0161] 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.

[0162] 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.

[0163] In one example, m can be a positive integer.

[0164] 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 first time unit in the occasion i.

[0165] If the first time unit in the occasion i is an SBFD time unit, the time unit type corresponding to the data transmission is SBFD. If the first time unit in the occasion i is a non-SBFD time unit, the time unit type corresponding to the data transmission is non-SBFD.

[0166] Exemplarily, the terminal 101 can determine the time unit type corresponding to the data transmission based on the type of time unit with a larger number in the occasion i of data transmission.

[0167] For example, there are 5 time units in the occasion i, including 3 SBFD time units and 2 non-SBFD time units, and the terminal 101 determines that the time unit type corresponding to the data transmission is SBFD.

[0168] Exemplarily, the terminal 101 can determine the time unit type corresponding to the data transmission based on a predefined manner.

[0169] 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.

[0170] For another example, in order to reduce the scheduling complexity of the network device and reduce inter-terminal interference, the terminal 101 can directly determine that the time unit type corresponding to the data transmission is non-SBFD.

[0171] In one example, the determination of the time unit type corresponding to the data transmission includes the first type and the second type, i.e., SBFD and non-SBFD.

[0172] Exemplarily, a related mechanism can be adopted, i.e., a scheme without distinguishing time unit types is adopted for unified power control. For example, the aforementioned unified TCI framework is adopted to determine the first TCI state.

[0173] The above is only an exemplary description, and the disclosure does not limit the scheme for determining the time unit type corresponding to the data transmission.

[0174] Step S2102, the network device 102 determines the time unit type corresponding to the data transmission.

[0175] 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.

[0176] Step S2103a, the network device 102 determines one or more TCI state lists.

[0177] In some embodiments, the network device 102 can determine one or more TCI state lists based on a predefined manner. In one example, one or more TCI state lists can be agreed by a protocol. Each TCI state list can include one or more TCI states.

[0178] 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.

[0179] In one example, multiple TCI state lists, e.g., 2 TCI state lists, can be agreed by 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.

[0180] In one example, multiple TCI state lists, e.g., 4 TCI state lists, can be agreed by protocol, and 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).

[0181] In some embodiments, the network device 102 can configure one or more TCI state lists based on its own policy.

[0182] The above is only an example description, and the disclosure does not limit the manner in which the network device 102 determines the TCI state list.

[0183] Step S2103b, the network device 102 sends the first indication signaling to the terminal 101.

[0184] In some embodiments, the terminal 101 can receive the first indication signaling.

[0185] In some embodiments, the first indication signaling is used to indicate one or more TCI state lists. Each TCI state list can include one or more TCI states.

[0186] In some embodiments, the first indication signaling can be radio resource control (RRC) signaling.

[0187] In one example, the first 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.

[0188] In one example, the first indication signaling can indicate multiple TCI state lists, e.g., 2 TCI state lists, 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.

[0189] 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.

[0190] In one example, the first indication signaling can indicate a plurality of TCI state lists, for example, 4 TCI state lists. Two lists of the TCI state lists can be used for uplink transmission (corresponding to the SBFD time unit and the non-SBFD time unit, respectively). The other two lists of the TCI state lists can be used for downlink transmission (corresponding to the SBFD time unit and the non-SBFD time unit, respectively).

[0191] 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 TCI state list corresponding to TRP #1 (or TRP #2) can be used as the TCI state corresponding to the non-SBFD time unit.

[0192] The number of TCI state lists can be more, which is not limited in the disclosure.

[0193] In some embodiments, step S2103b is an optional step. For example, when the network device 102 and the terminal 101 determine one or more TCI state lists based on a predefined manner, step S2103b can not be performed.

[0194] In some embodiments, steps S2103a and S2103b can be performed. For example, when the network device 102 configures one or more TCI state lists and then informs the terminal through the first indication signaling, steps S2103a and S2103b can be performed.

[0195] In step S2104, the terminal 101 determines one or more TCI state lists.

[0196] In some embodiments, the terminal 101 determines one or more TCI state lists based on a predefined manner.

[0197] 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.

[0198] In one example, multiple TCI state lists, e.g., 2 TCI state lists, can be agreed by protocol, and the TCI states in one list can be used for uplink transmission, and the TCI states in another list can be used for downlink transmission.

[0199] In one example, multiple TCI state lists, e.g., 4 TCI state lists, can be agreed by protocol, and the TCI states in 2 lists can be used for uplink transmission (corresponding to SBFD time unit and non-SBFD time unit respectively), and the TCI states in another 2 lists can be used for downlink transmission (corresponding to SBFD time unit and non-SBFD time unit respectively).

[0200] In some embodiments, the terminal 101 determines one or more TCI state lists based on the first indication signaling sent by the network device 102.

[0201] In one example, the first 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.

[0202] In one example, the first indication signaling can indicate multiple TCI state lists, e.g., 2 TCI state lists, and the TCI states in one list can be used for uplink transmission, and the TCI states in another list can be used for downlink transmission.

[0203] In one example, the first indication signaling can indicate multiple TCI state lists, e.g., 4 TCI state lists, and the TCI states in 2 lists can be used for uplink transmission (corresponding to SBFD time unit and non-SBFD time unit respectively), and the TCI states in another 2 lists can be used for downlink transmission (corresponding to SBFD time unit and non-SBFD time unit respectively).

[0204] In some embodiments, the terminal 101 determines one or more TCI state lists based on a predefined manner and the first indication signaling sent by the network device 102.

[0205] In one example, after the terminal 101 determines one or more TCI state lists based on the protocol agreement, the terminal 101 determines one or more of the above TCI state lists based on the first indication signaling.

[0206] Step S2105a, the network device 102 determines the first TCI state in one or more of the TCI state lists.

[0207] In some embodiments, the first TCI state can refer to the activated TCI state in each TCI state list, and the number of the first TCI state can be one or more, which is not limited by the present disclosure.

[0208] In some embodiments, the network device 102 can determine the first TCI state based on n TCI states in each TCI state list.

[0209] In one example, n is a positive integer.

[0210] For example, the network device 102 can determine the first TCI state based on 1, for example the first TCI state, in each TCI state list.

[0211] Assuming the number of TCI state lists is 1, the network device 102 determines the first TCI state in the first TCI state list as the first TCI state.

[0212] Assuming the number of TCI state lists is 2, the network device 102 determines the first TCI state in the TCI state list corresponding to the uplink transmission as the first TCI state corresponding to the uplink transmission. The first TCI state in the TCI state list corresponding to the downlink transmission is determined as the first TCI state corresponding to the downlink transmission.

[0213] Assuming the number of TCI state lists is 4, the network device 102 determines the first TCI state in the first TCI state list corresponding to the uplink transmission as the first TCI state (corresponding to the uplink transmission) corresponding to the SBFD and non-SBFD, respectively. The first TCI state in the first TCI state list corresponding to the downlink transmission is determined as the first TCI state (corresponding to the downlink transmission) corresponding to the SBFD and non-SBFD, respectively.

[0214] In some embodiments, the network device 102 can configure one or more first TCI states in each TCI state list.

[0215] Step S2105b, the network device 102 sends the second indication signaling to the terminal 101.

[0216] In some embodiments, the terminal 101 receives the second indication signaling.

[0217] In some embodiments, the second indication signaling is used to indicate one or more first TCI states configured by the network device 102 in each TCI state list.

[0218] In one example, the second indication signaling can indicate a set of the first TCI states, the set including one or more first TCI states.

[0219] In one example, the second indication signaling can indicate a combination of the first TCI states, each combination including one or more first TCI states.

[0220] In some embodiments, the second indication signaling can be a MAC CE.

[0221] In some embodiments, the network device 102 sends a MAC CE signaling corresponding to a TCI state list, indicating a combination (or referred to as a set) of the first TCI states that need to be activated, for example, a combination of up to 8 TCI states, corresponding to a specific TCI state combination, which includes one or more TCI states.

[0222] For example, if the MAC CE signaling corresponding to a TCI state list indicates that the combination of the first TCI states corresponds to up to two first TCI states, the two first TCI states can correspond to uplink and downlink at the same time, and / or the two available TCI states can correspond to different time unit types or the same time unit type.

[0223] For example, if the MAC CE signaling corresponding to multiple TCI state lists indicates that the combination (or referred to as a set) of the first TCI states corresponds to up to four first TCI states, the four first TCI states can correspond to uplink and downlink respectively, up to two first TCI states for a specific uplink or a specific downlink, and the two first TCI states can correspond to different time unit types or the same time unit type, which is not limited in the present disclosure.

[0224] In some embodiments, the second indication signaling can occupy k bits, where k can be a positive integer, so as to indicate the first TCI states that need to be activated, and of course, the number of the first TCI states can be greater than 4, in which case the second indication signaling can use more than 3 bits to indicate the first TCI states, and the specific indication manner is not limited in the present disclosure.

[0225] The above is only an example, and the content indicated by the second indication signaling is not limited in the present disclosure.

[0226] In some embodiments, step S2105b is an optional step, for example, in case that the network device 102 and the terminal 101 both determine the first TCI state in the one or more TCI state lists based on a predefined manner, step S2105b can not be performed.

[0227] In some embodiments, both step S2105a and step S2105b can be performed, for example, in case that the network device 102 and the terminal 101 configure the first TCI state in the one or more TCI state lists and then inform the terminal through the second indication signaling, step S2105a and step S2105b can be performed.

[0228] Step S2106, the terminal 101 determines the first TCI state in the one or more TCI state lists.

[0229] In some embodiments, the terminal 101 can determine the first TCI state in the one or more TCI state lists based on a predefined manner.

[0230] In one example, the terminal 101 can determine the first TCI state based on n TCI states in each TCI state list.

[0231] In one example, n is a positive integer.

[0232] For example, the terminal 101 can determine the first TCI state based on 1, for example, the 1st TCI state in each TCI state list.

[0233] In case that the number of TCI state lists is 1, the terminal 101 can determine the 1st TCI state in the TCI state list as the first TCI state.

[0234] In case that the number of TCI state lists is 2, the terminal 101 determines the 1st TCI state in the TCI state list #1 corresponding to the uplink transmission as the first TCI state corresponding to the uplink transmission. The 1st TCI state in the TCI state list corresponding to the downlink transmission is determined as the first TCI state corresponding to the downlink transmission.

[0235] In case that the number of TCI state lists is 4, the network device 102 determines the 1st TCI state in the 2 TCI state lists corresponding to the uplink transmission as the first TCI state corresponding to the SBFD and non-SBFD (corresponding to the uplink transmission) respectively. The 1st TCI state in the 2 TCI state lists corresponding to the downlink transmission is determined as the first TCI state corresponding to the SBFD and non-SBFD (corresponding to the downlink transmission) respectively.

[0236] In some embodiments, the terminal 101 can determine the first TCI states in the one or more TCI state lists based on the second indication signaling transmitted by the network device 102.

[0237] In one example, the second indication signaling is used to indicate one or more first TCI states in the one or more TCI state lists.

[0238] In one example, the second indication signaling can be used to indicate one or more first TCI states in each of the TCI state lists.

[0239] Exemplarily, the second indication signaling can indicate a set or combination of first TCI states, each set or combination can include one or more first TCI states.

[0240] In one example, the second indication signaling can indicate the index of the first TCI states in the TCI state lists.

[0241] In some embodiments, corresponding to one TCI state list, the terminal 101 determines the combination of first TCI states based on the MAC CE signaling, exemplarily, the combination of first TCI states can include at most 8 TCI states, corresponding to a specific combination of TCI states, which includes one or more available TCI states.

[0242] Exemplarily, if corresponding to one TCI state list, the terminal 101 determines the combination of TCI states based on the MAC CE signaling, the combination of TCI states can include at most two first TCI states, the two first TCI states can correspond to uplink and downlink at the same time, and / or, the two first TCI states can correspond to different time unit types respectively, or correspond to the same time unit type.

[0243] Exemplarily, if corresponding to multiple TCI state lists, the terminal 101 determines the combination of TCI states based on the MAC CE signaling, the combination of TCI states can include at most four first TCI states, the four first TCI states can correspond to uplink and downlink respectively, for a specific uplink or a specific downlink, at most two first TCI states, the two first TCI states can correspond to different time unit types respectively, or correspond to the same time unit type.

[0244] In some embodiments, the terminal 101 can determine the first TCI states in the one or more TCI state lists based on the second indication signaling transmitted by the network device 102 and a predefined manner.

[0245] In one example, the terminal 101 can determine n candidate TCI states in each TCI state list based on a predefined manner, n can be a positive integer, for example, n is 3, further, the terminal 101 can determine 2 activated first TCI states, for example, TCI state #1 and TCI state #3, in TCI state #1, TCI state #2 and TCI state #3 in each TCI state list based on the second indication signaling sent by the network device.

[0246] The above is only an example description, and the disclosure does not limit the scheme of the terminal 101 determining the first TCI state.

[0247] Step S2107a, the network device 102 determines the time unit type to which each of the first TCI states is applied.

[0248] In some embodiments, the network device 102 can determine the time unit type to which each of the first TCI states is applied based on a predefined manner.

[0249] In one example, the number of first TCI states is 1, and the network device 102 can determine that the time unit type to which the first TCI state can be applied is the first type and the second type, that is, the first TCI state can be used for SBFD time units and non-SBFD time units.

[0250] In one example, the number of first TCI states is 2, and the network device 102 can determine that the time unit type to which the first TCI state #1 can be applied is the first type, and the time unit type to which the first TCI state #1 can be applied is the second type. For example, the 2 first TCI states include TCI state #1 and TCI state #2, wherein TCI state #1 is applied to SBFD time units, and TCI state #2 is applied to non-SBFD time units. Alternatively, TCI state #1 is applied to non-SBFD time units, and TCI state #2 is applied to SBFD time units.

[0251] In one example, the number of first TCI states is 2, and the network device 102 can determine that the time unit type to which the first TCI state #1 can be applied is the first type and the second type, or the time unit type to which the first TCI state #2 can be applied is the first type and the second type.

[0252] For example, the 2 first TCI states include TCI state #1 and TCI state #2, wherein TCI state #1 can be applied to SBFD time units and non-SBFD time units.

[0253] For another example, the 2 first TCI states include TCI state #1 and TCI state #2, wherein the TCI state #2 is applied to the non-SBFD time unit and the SBFD time unit.

[0254] In one example, the number of the first TCI states is 4, the first TCI state #1 and the first TCI state #2 correspond to the uplink transmission, the first TCI state #3 and the first TCI state #4 correspond to the downlink transmission, the time unit type to which the first TCI state #1 is applied is determined as the first type, and the time unit type to which the first TCI state #2 is applied is determined as the second type. In one example, the number of the first TCI states is 4,

[0255] The first TCI state #1 and the first TCI state #2 correspond to the uplink transmission, the first TCI state #3 and the first TCI state #4 correspond to the downlink transmission, the time unit type to which the first TCI state #3 is applied is determined as the first type, and the time unit type to which the first TCI state #4 is applied is determined as the second type.

[0256] Exemplarily, the index of the first TCI state #1 can be greater than the index of the first TCI state #2.

[0257] Exemplarily, the index of the first TCI state #1 can be less than the index of the first TCI state #2.

[0258] Exemplarily, in the TCI state list, the position index corresponding to the first TCI state #1 is less than the position index corresponding to the first TCI state #2.

[0259] Exemplarily, in the TCI state list, the position index corresponding to the first TCI state #3 is greater than the position index corresponding to the first TCI state #4.

[0260] Exemplarily, the index of the first TCI state #3 can be greater than the index of the first TCI state #4.

[0261] Exemplarily, the index of the first TCI state #3 can be less than the index of the first TCI state #4.

[0262] Exemplarily, in the TCI state list, the position index corresponding to the first TCI state #3 is less than the position index corresponding to the first TCI state #4.

[0263] Exemplarily, in the TCI state list, the position index corresponding to the first TCI state #3 is greater than the position index corresponding to the first TCI state #4.

[0264] Exemplarily, in the TCI state list, the position index corresponding to the first TCI state #3 is smaller than the position index corresponding to the first TCI state #4.

[0265] Exemplarily, in the TCI state list, the position index corresponding to the first TCI state #3 is greater than the position index corresponding to the first TCI state #4.

[0266] Exemplarily, the index of each first TCI state can be determined based on MAC CE or RRC signaling.

[0267] Exemplarily, the position index corresponding to each first TCI state can be determined based on MAC CE or RRC signaling.

[0268] In some embodiments, the network device 102 can configure the time unit type to which each first TCI state is applied.

[0269] The above is only an exemplary description, and the disclosure does not limit the manner of determining the time unit type to which the first TCI state is applied.

[0270] Step S2107b, the network device 102 sends the third indication signaling to the terminal 101.

[0271] In some embodiments, the terminal 101 receives the third indication signaling.

[0272] In some embodiments, the third indication signaling is used to indicate the time unit type to which each first TCI state configured by the network device 102 is applied.

[0273] In some embodiments, the third indication signaling can include but is not limited to at least one of the following: SBFD special indication signaling; existing indication signaling.

[0274] In one example, an SBFD special downlink control information field can be added in the SBFD special indication signaling, wherein the downlink control information field can be used to indicate the time unit type to which each first TCI state is applied.

[0275] For example, when the bit value of the downlink control information field in the SBFD special indication signaling is “1” or “0”, it can be used to indicate that 1 first TCI state is applied to SBFD time units and non-SBFD time units.

[0276] For example, when the bit value of the downlink control information field in the SBFD special indication signaling is “1” or “0”, it can be used to indicate that 1 first TCI state is applied to SBFD time units.

[0277] For example, when the bit value of the downlink control information field in the SBFD special indication signaling is “1” or “0”, it can be used to indicate that one first TCI state is applied to the non-SBFD time unit.

[0278] For example, when the bit value of the downlink control information field in the SBFD special indication signaling is “1”, it can be used to indicate that the first TCI state #1 of the two first TCI states is applied to the SBFD time unit, and the first TCI state #2 is applied to the non-SBFD time unit.

[0279] For example, when the bit value of the downlink control information field in the SBFD special indication signaling is “0”, it can be used to indicate that the first TCI state #1 of the two first TCI states is applied to the non-SBFD time unit, and the first TCI state #2 is applied to the SBFD time unit.

[0280] For example, when the bit value of the downlink control information field in the SBFD special indication signaling is “1” or “0”, it can be used to indicate that the first TCI state #1 corresponding to the uplink transmission of the four first TCI states is applied to the SBFD time unit, and the first TCI state #2 is applied to the non-SBFD time unit, and / or, it can be used to indicate that the first TCI state #3 corresponding to the downlink transmission is applied to the SBFD time unit, and the first TCI state #4 is applied to the non-SBFD time unit.

[0281] For example, when the bit value of the downlink control information field in the SBFD special indication signaling is “00” or “01”, it can be used to indicate that one first TCI state is applied to the SBFD time unit and the non-SBFD time unit.

[0282] For example, when the bit value of the downlink control information field in the SBFD special indication signaling is “00” or “01”, it can be used to indicate that one first TCI state is applied to the SBFD time unit.

[0283] For example, when the bit value of the downlink control information field in the SBFD special indication signaling is “00” or “01”, it can be used to indicate that one first TCI state is applied to the non-SBFD time unit.

[0284] For example, when the bit value of the downlink control information field in the SBFD special indication signaling is “00” or “01”, it can be used to indicate that the first TCI state #1 of the two first TCI states is applied to the SBFD time unit, and the first TCI state #2 is applied to the non-SBFD time unit.

[0285] For another example, when the bit value of the downlink control information field in the SBFD-specific indication signaling is "10" or "11", it can be used to indicate that the first TCI state #1 of the two first TCI states is applied to the non-SBFD time unit, and the first TCI state #2 is applied to the SBFD time unit.

[0286] For another example, when the bit value of the downlink control information field in the SBFD-specific indication signaling is "10" or "11", it can be used to indicate that the first TCI state #1 of the two first TCI states is applied to the non-SBFD time unit, and the first TCI state #2 is applied to the SBFD time unit.

[0287] For another example, when the bit value of the downlink control information field in the SBFD-specific indication signaling is "10" or "11", it can be used to indicate that the first TCI state #1 of the two first TCI states is applied to the non-SBFD time unit, and the first TCI state #2 is applied to the SBFD time unit.

[0288] For another example, when the bit value of the downlink control information field in the SBFD-specific indication signaling is "10" or "11", it can be used to indicate that the first TCI state #1 of the two first TCI states is applied to the non-SBFD time unit, and the first TCI state #2 is applied to the SBFD time unit.

[0289] For another example, when the bit value of the downlink control information field in the SBFD-specific indication signaling is "10" or "11", it can be used to indicate that the first TCI state #1 of the two first TCI states is applied to the non-SBFD time unit, and the first TCI state #2 is applied to the SBFD time unit.

[0290] The above is only an exemplary description, and the downlink control information field in the SBFD-specific indication signaling can be set to other bit values, thereby indicating the time unit type to which each first TCI state is applied.

[0291] In one example, when the third indication signaling is an existing indication signaling, an existing information field in the existing indication signaling can be reused to indicate the time unit type to which each first TCI state is applied.

[0292] In some embodiments, the third indication signaling can be a DCI, where the DCI can be a DCI dedicated to SBFD or a DCI of an existing format.

[0293] In one example, a TCI selection field (an existing information field) can be included in the DCI, and the TCI selection field indicates the time unit type to which each first TCI state is applied.

[0294] For example, the bit value of the TCI selection field and the indicated time unit type to which each first TCI state is applied can be as shown in Table 2.

[0295] Table 2

[0296] Alternatively, if the indication value of the TCI selection field indicates any one of 0, 00, or 01, the first TCI is applied to the SBFD time unit type, and if the indication value of the TCI selection field indicates any one of 1, 10, or 11, the first TCI is applied to the non-SBFD time unit type.

[0297] Alternatively, if the indication value of the TCI selection field indicates any one of 0, 00, or 01, the first TCI is applied to the non-SBFD time unit type, and if the indication value of the TCI selection field indicates any one of 1, 10, or 11, the first TCI is applied to the SBFD time unit type.

[0298] For example, the bit value of the TCI selection field and the indicated time unit type to which each first TCI state is applied can also be as shown in Table 3.

[0299] Table 3

[0300] The above is only an example, and the bit value of the DCI field can also be set to other values, and the present disclosure does not limit the relationship between the bit value and the corresponding applied time unit type.

[0301] Of course, when the third indication signaling is a DCI, a DCI field dedicated to SBFD can also be newly added to indicate the time unit type to which each first TCI state is applied, and the present disclosure does not limit this.

[0302] In some embodiments, step S2107b is an optional execution step, for example, when the network device 102 and the terminal 101 determine the time unit type to which each first TCI state is applied based on a pre-defined manner, step S2107b can not be executed.

[0303] In some embodiments, both step S2107a and step S2107b can be performed. For example, in the case that the network device 102 configures the time unit type to which each first TCI state is applied and signals the terminal 101 through the third indication, step S2107a and step S2107b can be performed.

[0304] Step S2108, the terminal 101 determines the time unit type to which each first TCI state is applied.

[0305] In some embodiments, the terminal 101 determines the time unit type to which each first TCI state is applied based on a predefined manner.

[0306] In one example, the number of first TCI states is 1, and the terminal 101 can determine that the time unit type to which the first TCI state can be applied is the first type and the second type, i.e., the first TCI state can be used for SBFD time units and non-SBFD time units.

[0307] In one example, the number of first TCI states is 2, and the terminal 101 can determine that the time unit type to which the first TCI state #1 can be applied is the first type, and the time unit type to which the first TCI state #2 can be applied is the second type.

[0308] In one example, the number of first TCI states is 2, and the terminal 101 can determine that the time unit type to which the first TCI state #1 can be applied is the first type and the second type, or the time unit type to which the first TCI state #2 can be applied is the first type and the second type.

[0309] In one example, the number of first TCI states is 4, the first TCI state #1 and the first TCI state #2 correspond to uplink transmission, and the network device 102 can determine that the time unit type to which the first TCI state #1 is applied is the first type, and determine that the time unit type to which the first TCI state #2 is applied is the second type. And / or, the terminal 101 can determine that the time unit type to which the first TCI state #1 can be applied is the first type and the second type, or the time unit type to which the first TCI state #2 can be applied is the first type and the second type.

[0310] In one example, the number of the first TCI states is 4, the first TCI state #3 and the first TCI state #4 correspond to the downlink transmission, the terminal 101 can determine that the time unit type to which the first TCI state #3 is applied is the first type, and determine that the time unit type to which the first TCI state #4 is applied is the second type. Alternatively, the terminal 101 can determine that the time unit type to which the first TCI state #3 can be applied is the first type and the second type, or the time unit type to which the first TCI state #4 can be applied is the first type and the second type.

[0311] Illustratively, the index of the first TCI state #1 can be greater than the index of the first TCI state #2.

[0312] Illustratively, the index of the first TCI state #1 can be less than the index of the first TCI state #2.

[0313] Illustratively, in the TCI state list, the position index corresponding to the first TCI state #1 is less than the position index corresponding to the first TCI state #2.

[0314] Illustratively, in the TCI state list, the position index corresponding to the first TCI state #3 is greater than the position index corresponding to the first TCI state #4.

[0315] Illustratively, the index of the first TCI state #3 can be greater than the index of the first TCI state #4.

[0316] Illustratively, the index of the first TCI state #3 can be less than the index of the first TCI state #4.

[0317] Illustratively, in the TCI state list, the position index corresponding to the first TCI state #3 is less than the position index corresponding to the first TCI state #4.

[0318] Illustratively, in the TCI state list, the position index corresponding to the first TCI state #3 is greater than the position index corresponding to the first TCI state #4.

[0319] Illustratively, in the TCI state list, the position index corresponding to the first TCI state #3 is less than the position index corresponding to the first TCI state #4.

[0320] Illustratively, in the TCI state list, the position index corresponding to the first TCI state #3 is greater than the position index corresponding to the first TCI state #4.

[0321] Illustratively, the index of each first TCI state can be determined based on MAC CE or RRC signaling.

[0322] Exemplarily, the position index corresponding to each first TCI state can be determined based on MAC CE or RRC signaling.

[0323] The above is only an exemplary illustration, and the disclosure does not limit the manner in which the terminal 101 determines the time unit type to which each first TCI state is applied.

[0324] In some embodiments, the terminal 101 determines the time unit type to which each first TCI state is applied based on the third indication signaling sent by the network device 102.

[0325] In one example, the third indication signaling can include, but is not limited to, at least one of the following: SBFD-specific indication signaling; existing indication signaling. In one example, an SBFD-specific downlink control information field can be added in the SBFD-specific indication signaling, where the downlink control information field can be used to indicate the time unit type to which each first TCI state is applied.

[0326] In one example, when the third indication signaling is the existing indication signaling, an existing information field in the existing indication signaling can be reused to indicate the time unit type to which each first TCI state is applied.

[0327] In some embodiments, the third indication signaling can be DCI, where the DCI can be SBFD-specific DCI or DCI of an existing format.

[0328] In one example, the DCI can include a TCI selection field (existing information field), and the TCI selection field is used to indicate the time unit type to which each first TCI state is applied.

[0329] Exemplarily, the bit value of the TCI selection field indicates the time unit type to which each first TCI state is applied, for example, as shown in Table 2 or Table 3.

[0330] The terminal 101 can determine the time unit type to which each first TCI state is applied based on Table 2 or Table 3 based on the bit value of the TCI selection field.

[0331] Of course, when the third indication signaling is DCI, an SBFD-specific downlink control information field can also be added to indicate the time unit type to which each first TCI state is applied, and the disclosure does not limit this.

[0332] In some embodiments, the terminal 101 determines the time unit type to which each first TCI state is applied based on a predefined manner and the third indication signaling sent by the network device 102.

[0333] In one example, the protocol stipulates an initial time unit type to which the first TCI state is applied, for example, the first TCI state is applied to SBFD time units, and the first TCI state is applied to non-SBFD time units. The terminal 101 receives the third indication signaling sent by the network device 102, and determines that the time unit type to which the first TCI state is applied changes, for example, the first TCI state is applied to non-SBFD time units, and the first TCI state is applied to SBFD time units.

[0334] The above is only an example description, and the disclosure does not limit the scheme of the terminal 101 determining the time unit type to which each first TCI state is applied.

[0335] Step S2109, the terminal 101 determines the second TCI state corresponding to the data transmission.

[0336] In some embodiments, the second TCI state refers to the TCI state actually used for data transmission.

[0337] In some embodiments, the second TCI state can be one or more of the aforementioned activated first TCI states.

[0338] In some embodiments, the terminal 101 can determine the actual second TCI state corresponding to the data transmission based on the time unit type corresponding to the data transmission and the time type to which each first TCI state is applied.

[0339] In one example, the time unit type corresponding to the timing i of the data transmission is SBFD, and the first TCI state #1 is applied to SBFD. Then the terminal 101 determines that the second TCI state corresponding to the data transmission is the first TCI state #1.

[0340] In one example, the time unit type corresponding to the timing i of the data transmission is non-SBFD, and the first TCI state #2 is applied to non-SBFD. Then the terminal 101 determines that the second TCI state corresponding to the data transmission is the first TCI state #2.

[0341] In one example, the time unit type corresponding to the timing i of the data transmission is SBFD, and the first TCI state #1 is applied to SBFD and non-SBFD. Then the terminal 101 determines that the second TCI state corresponding to the data transmission is the first TCI state #1.

[0342] In one example, the time unit type corresponding to the timing i of the data transmission is non-SBFD, and the first TCI state #2 is applied to SBFD and non-SBFD. Then the terminal 101 determines that the second TCI state corresponding to the data transmission is the first TCI state #2.

[0343] In one example, the time unit type corresponding to the occasion i of the data transmission is SBFD and non-SBFD, the first TCI state #1 is applied to SBFD, and the first TCI state #2 is applied to non-SBFD, and the terminal 101 determines that the second TCI state corresponding to the data transmission is the first TCI state #1 and the first TCI state #2.

[0344] In one example, the time unit type corresponding to the occasion i of the data transmission is SBFD and non-SBFD, the first TCI state #1 is applied to SBFD and non-SBFD, and the terminal 101 determines that the second TCI state corresponding to the data transmission is the first TCI state #1.

[0345] In one example, the time unit type corresponding to the occasion i of the data transmission is SBFD and non-SBFD, the first TCI state #2 is applied to SBFD and non-SBFD, and the terminal 101 determines that the second TCI state corresponding to the data transmission is the first TCI state #2.

[0346] In some embodiments, if the time unit type corresponding to the occasion i of the data transmission is SBFD and non-SBFD, the terminal 101 can determine the second TCI state corresponding to the data transmission regardless of the time unit type corresponding to the data transmission.

[0347] Wherein, the second TCI state irrelevant to the time unit type corresponding to the data transmission can mean that the second TCI state actually used by the data transmission is no longer determined based on the time unit type corresponding to the data transmission.

[0348] In one example, the terminal 101 can fall back to the conventional mechanism to determine the second TCI state.

[0349] For example, the terminal 101 determines the second TCI state corresponding to the data transmission according to the related technology, such as the TCI state (TCI-State) configured based on the downlink or joint TCI state list (dl-OrJointTCI-StateList) or the uplink TCI state (TCI-UL-State). At this time, the determined TCI state is irrelevant to the time unit type, and can be used for uplink and downlink, or for specific uplink or specific downlink.

[0350] Step S2110, the network device 102 determines the second TCI state corresponding to the data transmission.

[0351] In some embodiments, the network device 102 determines the second 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.

[0352] In some embodiments, if the time unit type corresponding to the timing i of the data transmission is SBFD and non-SBFD, the network device 102 can also determine the second TCI state corresponding to the data transmission regardless of the time unit type corresponding to the data transmission. In some embodiments, after the terminal 101 and the network device 102 both determine the second TCI state corresponding to the data transmission, the uplink data transmission or the downlink data transmission can be performed based on the determined second TCI state.

[0470] Example 1: The indication signaling is SBFD specific indication signaling;

[0471] Optionally, a DCI field is added to indicate the time unit type to which the TCI state is applied;

[0472] Example 2: The indication signaling is existing indication signaling;

[0473] Optionally, the terminal determines the time unit type to which the TCI state is applied based on the existing TCI selection field.

[0474] On the network device side, which is hereinafter referred to as the base station side:

[0475] The base station 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 on which the data transmission is performed, and determines the time unit type to which the TCI state is applied based on a predefined rule; or, sends indication signaling to indicate the time unit type to which the TCI state is applied:

[0485] Example 2: the indication signaling is existing indication signaling;

[0486] Example: the terminal determines the time unit type to which the TCI state is applied based on the existing TCI selection field.

[0487] The following will elaborate the specific embodiments of the application from the perspective of the terminal:

[0488] Embodiment:

[0489] Assuming that the terminal is a terminal supporting the SBFD feature, the terminal can transmit uplink data on the UL subband based on the base station configuration on the DL or flexible symbol, and / or receive downlink data on the DL subband.

[0490] Another possible embodiment, the terminal supporting the SBFD feature can receive downlink data on the DL subband based on the base station configuration on the UL or flexible symbol, and / or transmit uplink data on the UL subband.

[0491] As described above, the terminal can determine the time domain position of the SBFD time unit based on the base station configuration and the corresponding rules. If the terminal transmits data on the SBFD time unit based on the scheduling, the terminal determines that the data transmission corresponds to the SBFD time unit. Taking the DCI scheduled PUSCH as an example, if the terminal determines that the PUSCH is transmitted on time unit n based on the DCI scheduling information. Correspondingly, if the terminal determines that the time unit n corresponds to the SBFD time unit based on the base station configuration and the corresponding rules, the terminal determines that the PUSCH is transmitted on the SBFD time unit. Illustratively, it is transmitted within the UL subband frequency domain range corresponding to time unit n. On the contrary, if the terminal determines that the time unit is non-SBFD based on the base station configuration or the corresponding pre-defined rules, the terminal determines that the PUSCH is transmitted on the non-SBFD time unit. Illustratively, it is transmitted within the UL BWP frequency domain range corresponding to time unit n.

[0492] Corresponding to uplink data at a transmission occasion i, if the occasion i contains both SBFD time units and non-SBFD time units, the terminal determines the time unit type corresponding to the occasion i based on at least one of the following manners;

[0493] The terminal determines that the occasion i corresponds to SBFD time units, or the terminal determines that the occasion i corresponds to non-SBFD time units.

[0494] The terminal determines the time unit type corresponding to the occasion i based on the 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 time unit type corresponding to the 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 the occasion i is non-SBFD.

[0495] The terminal determines that the occasion i corresponds to both SBFD time units and non-SBFD time units.

[0496] Alternatively, if the occasion i contains both SBFD time units and non-SBFD time units, the terminal performs a unified power control mechanism for different time unit types, for example, using an existing mechanism to determine the corresponding power control parameters.

[0497] As described above, in the SBFD scenario, the embodiment of the present application designs a scheme for determining the TCI state of the corresponding data transmission on the SBFD time unit and the non-SBFD time unit based on a pre-defined or signaling indication manner.

[0498] The data transmission includes but is not limited to at least one of the following:

[0499] Uplink transmission, which includes but is not limited to PUSCH, SRS, PUCCH, etc.

[0500] Downlink transmission, which includes but is not limited to PDCCH, PDSCH, CSI-RS, SSB, etc.

[0501] 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.

[0502] Embodiment 1:

[0503] The terminal determines the TCI state based on a predefined rule or a signaling indication manner, as described above;

[0504] For example, the terminal determines one or more TCI state lists based on a predefined or signaling configured manner. For example, the terminal determines one TCI state list, and the TCI state can be applied to uplink and downlink simultaneously. For example, the terminal determines two TCI state lists, and the two TCI state lists correspond to uplink and downlink respectively.

[0505] Predefined rule:

[0506] Corresponding to the TCI state list, the terminal determines the first TCI state in the one or more TCI lists as the TCI state corresponding to data transmission. For example, in the case of one TCI state list, the terminal determines the first TCI state in the TCI state list as the TCI state corresponding to data transmission. For example, in the case of two TCI state lists, the terminal determines the first TCI state in the two TCI state lists as the two TCI states corresponding to data transmission.

[0507] Signaling indication:

[0508] Corresponding to the TCI state list, the terminal receives MAC CE signaling to determine the possible TCI state combination corresponding to data transmission. For example, there are at most 8 TCI combinations, and corresponding to a specific TCI combination, there is one or more TCI states.

[0509] For example, if corresponding to one TCI state list, the terminal determines that the TCI combination corresponds to at most two TCI states, and the at most two TCI states can correspond to uplink and downlink simultaneously, or the at most two TCI states can correspond to different time unit types respectively, or the at most two TCI states can correspond to the same time unit type. The specific mapping manner is described in the following embodiments.

[0510] For example, if the terminal determines that the TCI combination corresponds to a maximum of four TCI states, the maximum of four TCI states can correspond to uplink and downlink, a specific uplink or downlink, a maximum of two TCI states, and the maximum of two TCI states can correspond to different time unit types or the same time unit type. The specific mapping manner is described in the following embodiments.

[0511] Based on the determined multiple TCI combinations, the terminal determines one of the multiple TCI combinations indicated by the MAC CE based on the DCI indication signaling, thereby determining one or more TCI states of the configured data transmission.

[0512] In a possible implementation, the terminal determines the time unit type of the TCI state corresponding to the data transmission based on the time unit type of the data transmission. The specific implementation has been described above and will not be repeated here.

[0513] In a possible implementation, the terminal determines two TCI states corresponding to the data transmission based on a predefined rule or signaling indication manner, and determines the time unit type to which the TCI states are applied based on the predefined rule or signaling indication manner.

[0514] Sub-embodiment 1:

[0515] The terminal determines the two TCI states based on the above manner, and determines the time unit type to which the two TCI states are applied based on a predefined rule. The predefined rule includes one or more of the following:

[0516] The first TCI state is applied to the SBFD time unit, and the second TCI state is applied to the non-SBFD time unit.

[0517] The second TCI state is applied to the SBFD time unit, and the first TCI state is applied to the non-SBFD time unit.

[0518] The first TCI state is applied to the SBFD time unit and the non-SBFD time unit.

[0519] The second TCI state is applied to the SBFD time unit and the non-SBFD time unit.

[0520] Exemplarily, the terminal determines the first TCI state and the second TCI state based on TCI state indexes, and exemplarily, the first TCI state corresponds to an index smaller than an index of the second TCI state, or the second TCI state corresponds to an index smaller than an index of the first TCI state.

[0521] Exemplarily, the terminal determines the first TCI state and the second TCI state based on position indexes of the TCI states in a list, and exemplarily, the first TCI state corresponds to a position index smaller than a position index of the second TCI state, or the second TCI state corresponds to a position index smaller than a position index of the first TCI state.

[0522] The TCI index and / or the position index are determined based on MAC CE or RRC signaling.

[0523] Sub-embodiment 2:
