[0209] FIG2A is an interactive diagram illustrating a method for activating a TCI state according to an embodiment of the present disclosure. As shown in FIG2A , an embodiment of the present disclosure relates to a method for activating a TCI state, and the method includes:

[0210] Step S2101: The network device sends at least one first information to the terminal.

[0211] In some embodiments, at least one first information is used to indicate a TCI state corresponding to the first TRP and a TCI state corresponding to the second TRP.

[0212] In some embodiments, the network device includes a first TRP and a second TRP.

[0213] In some embodiments, at least one first information includes one first information or multiple first information. Optionally, if at least one first information includes one first information, the one first information is used to indicate both the activation of the TCI state corresponding to the first TRP and the activation of the TCI state corresponding to the second TRP. Optionally, if at least one first information includes multiple first information, each first information in the multiple first information is used to activate a TCI state. For example, the first first information is used to indicate the activation of the TCI state corresponding to the first TRP, and the second first information is used to indicate the activation of the TCI state corresponding to the second TRP.

[0214] In some embodiments, the TCI state is used to indicate the beam direction, which can be understood as the terminal determining the corresponding beam direction according to the TCI state, and then transmitting data according to the beam direction corresponding to the activated TCI state.

[0215] In an embodiment of the present disclosure, the network device sends at least one first information, and the at least one first information indicates activation of multiple TCI states.

[0216] In some embodiments, the terminal receives at least one first message. Alternatively, it can be understood that the terminal receives at least one first message sent by a network device.

[0217] In some embodiments, the network device sends at least one first information to the terminal.

[0218] In some embodiments, the name of the first information is not limited, and can be, for example, activation information, indication information, TCI information, etc.

[0219] In some embodiments, the first information may be MAC CE, RRC, DCI or other information, which is not limited in the embodiments of the present disclosure.

[0220] Step S2102: The first TRP and the second TRP send second information to the terminal.

[0221] In some embodiments, the second information is used to synchronize the TRP corresponding to the second information with the terminal.

[0222] In some embodiments, the second information is SSB, CSI-RS or other information, which is not limited in the embodiments of the present disclosure.

[0223] In some embodiments, the terminal receives second information sent by the first TRP and the second TRP.

[0224] In some embodiments, the name of the second information is not limited, and can be, for example, activation information, indication information, TCI information, etc.

[0225] In some embodiments, the second information may be MAC CE, RRC, DCI or other information, which is not limited in the embodiments of the present disclosure.

[0226] It should be noted that the embodiment of the present disclosure is described by taking the network device including the first TRP and the second TRP as an example. In another embodiment, the network device may also include three or more TRPs, that is, at least one first information is used to indicate the activation of the TCI states corresponding to the three or more TRPs.

[0227] Step S2103: The terminal determines the delay for activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP based on the duration interval between the first time domain unit of at least one first information and the second time domain unit of the second information and at least one of the periods of the second information.

[0228] In some embodiments, the first time domain unit of the at least one first information refers to the time domain unit corresponding to when the terminal completes parsing the at least one first information; the second time domain unit of the second information refers to the second time domain unit when the terminal receives the second information.

[0229] In some embodiments, the first time domain unit refers to the time domain unit in which the parsing of the first information is completed. In the embodiments of the present disclosure, after receiving the first information, the terminal needs to parse the first information. Parsing the first information requires a certain time, and after the time has elapsed, the first time domain unit is reached. Optionally, the time duration for the terminal to parse the first information is 3ms. Optionally, the first time domain unit is a time slot, a symbol, or other, which is not limited in the embodiments of the present disclosure.

[0230] In some embodiments, the second time domain unit refers to the moment when the first second information sent by the TRP corresponding to each second time domain unit is received after the first time domain unit. In the embodiment of the present disclosure, different TRPs achieve synchronization by sending different second information. The second time domain unit refers to the moment when the terminal receives the first second information after the TRP sends the first second information after the first time domain unit. Optionally, the second time domain unit is a time slot, a symbol or other, which is not limited in the embodiment of the present disclosure.

[0231] In some embodiments, the second information is used for synchronization. Optionally, the second information is SSB, or other information, which is not limited in the embodiments of the present disclosure.

[0232] In some embodiments, after receiving the first information, the terminal also needs to send feedback information to the network device. Therefore, it takes a certain amount of time for the terminal to send the feedback information. Optionally, the feedback information includes at least one of an acknowledgment message or a negative acknowledgement message. For example, the acknowledgment message is a HARQ-ACK. The negative acknowledgement message is a HARQ-NACK.

[0233] In some embodiments, the terminal's activated TCI state list does not include multiple TCI states, and the activated TCI state list includes at least one candidate TCI state. In embodiments of the present disclosure, if at least one first information indicates that multiple TCI states activated are not present in the activated TCI state list, it is necessary to consider at least one of the duration between the first time domain unit and each of the multiple second time domain units and the period of the second time domain units to determine the delay in activating the TCI state.

[0234] In the embodiments of the present disclosure, there are various situations for determining the delay of activating the TCI state. The following describes how to determine the delay of the TCI state.

[0235] In some embodiments, a maximum time interval is determined from the time intervals between the first time domain unit and each of the second time domain units, and a first delay is determined based on the maximum time interval, where the first delay is used to indicate the total delay of activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP.

[0236] In some embodiments, determining the first delay based on the maximum duration interval includes: determining the first delay based on the time of receiving the first information, the duration of sending the feedback information, the duration of parsing the first information, the maximum duration interval, and the duration of parsing the second information.

[0237] In some embodiments, a maximum time interval with the largest time interval is determined from the time intervals between the first time domain unit and each second time domain unit, and a first delay is determined based on the maximum time interval. The first delay is used to indicate the total delay of activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP.

[0238] In the embodiment of the present disclosure, the activation delays of the TCI states of the first TRP and the second TRP are defined together, so it is sufficient to determine a delay for activating the TCI state, and therefore it is sufficient to determine the maximum time interval as the delay for activating the TCI state.

[0239] For example, referring to FIG2B , one MAC CE activates the TCI states of two TRPs. The time interval of TRP1 is smaller than the time interval of TRP2. Therefore, the time interval of TRP2 is determined as the delay for activating the TCI state.

[0240] Optionally, the second time domain unit of the second information sent by the first TRP does not overlap with the second time domain unit of the second information sent by the second TRP. The maximum time interval is determined from the time intervals between the first time domain unit and each of the second time domain units. The first delay is determined based on the maximum time interval. The first delay is used to indicate the total delay of activating the TCI state corresponding to the first TRP and the delay of activating the TCI state corresponding to the second TRP.

[0241] Optionally, the second time domain unit of the second information sent by the first TRP does not overlap with the second time domain unit of the second information sent by the second TRP, and the maximum time interval with the largest time interval is determined from the time interval between the first time domain unit and each second time domain unit, and the maximum time interval is determined as the delay for activating the TCI state. Alternatively, it can also be understood that, when multiple second time domain units do not overlap, the maximum time interval with the largest time interval is determined from the time interval between the first time domain unit and each second time domain unit, and the maximum time interval is determined as the delay for activating the TCI state.

[0242] Optionally, in the case where a first information is used to activate multiple TCI states, the maximum time interval is determined from the time intervals between the first time domain unit and each of the second time domain units, and a first delay is determined based on the maximum time interval. The first delay is used to indicate the total delay of activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP.

[0243] Optionally, when a first information is used to activate multiple TCI states, a maximum duration interval with the largest duration interval is determined from the duration intervals between the first time domain unit and each second time domain unit, and the maximum duration interval is determined as the delay for activating the TCI state.

[0244] It should be noted that the time delay from receiving the first information to activating the TCI state can be expressed by the formula:

[0245] Wherein, n is the time of receiving the first information, T HARQ The duration of sending feedback information. The delay is 3ms, TO k The preset value is 1, T first-SSB_TRP1 is the duration between the first time domain unit and the second time domain unit of TRP1, T first-SSB_TRP2 is the duration between the first time domain unit and the second time domain unit of TRP2, T SSB-proc To parse the duration of SSB, NR slot length is the length of the time domain unit.

[0246] In some embodiments, a minimum period is determined from the period of each second information; based on the time interval between the first time domain unit and each second time domain unit and the minimum period, the delay for activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP is determined.

[0247] In some embodiments, a minimum period with the smallest period is determined from the periods of the second time domain units, and the delay for activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP is determined based on the time interval between the first time domain unit and each second time domain unit in the multiple second time domain units and the minimum period.

[0248] In the embodiment of the present disclosure, the activation delays of the TCI states of the first TRP and the second TRP are defined together, so it is sufficient to determine a delay for activating the TCI state, and therefore it is sufficient to determine the maximum time interval as the delay for activating the TCI state.

[0249] In the embodiment of the present disclosure, the periods corresponding to different second time domain units may be different. Therefore, the period with the smallest period is determined from different second time domain units, and then the delay of the TCI state is determined based on the time interval and the minimum period between the first time domain unit and each second time domain unit in the multiple second time domain units.

[0250] Optionally, the sum of the time interval and the minimum period between the first time domain unit and any second time domain unit is obtained, and the first delay is determined based on the sum. The first delay is used to indicate the total delay of activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP.

[0251] In some embodiments, determining the first delay based on the sum value includes: determining the first delay based on the time of receiving the first information, the duration of sending the feedback information, the duration of parsing the first information, the sum value, and the duration of parsing the second information.

[0252] Optionally, a sum of a time interval between the first time domain unit and any second time domain unit among a plurality of second time domain units and a minimum period is obtained, and a time delay of the TCI state is determined based on the sum.

[0253] For example, referring to FIG2C , a MAC CE activates the TCI state of two TRPs, and the SSB period of TRP1 is smaller than the SSB period of TRP2. Therefore, the sum of the duration interval between the first time domain unit and any one of the multiple second time domain units and the minimum period is determined as the delay for activating the TCI state.

[0254] Optionally, in the case where a first information is used to activate multiple TCI states, the minimum period is determined from the period of each second information; based on the time interval between the first time domain unit and each second time domain unit and the minimum period, the delay for activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP is determined.

[0255] Optionally, in the case where a first information is used to activate multiple TCI states, a minimum period with the smallest period is determined from the periods of the second time domain units, and the delay of the TCI state is determined based on the time interval between the first time domain unit and each second time domain unit in the multiple second time domain units and the minimum period.

[0256] Optionally, when the first information has a one-to-one correspondence with multiple TCI states, the minimum period is determined from the period of each second information; based on the time interval between the first time domain unit and each second time domain unit and the minimum period, the delay for activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP is determined.

[0257] Optionally, when the first information has a one-to-one correspondence with multiple TCI states, the minimum period with the smallest period is determined from the period of the second time domain unit, and the delay of the TCI state is determined based on the time interval between the first time domain unit and each second time domain unit in the multiple second time domain units and the minimum period.

[0258] Optionally, the second time domain unit of the second information sent by the first TRP overlaps with the second time domain unit of the second information sent by the second TRP, and the minimum period is determined from the period of each of the second information; based on the time interval between the first time domain unit and each of the second time domain units and the minimum period, the delay for activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP is determined.

[0259] Optionally, the second time domain unit of the second information sent by the first TRP overlaps with the second time domain unit of the second information sent by the second TRP, and the minimum period with the smallest period is determined from the periods of the second time domain units. The delay of the TCI state is determined based on the time interval and the minimum period between the first time domain unit and each second time domain unit in the multiple second time domain units.

[0260] It should be noted that the time delay from receiving the first information to activating the TCI state can be expressed by the formula:

[0261] Wherein, n is the time of receiving the first information, T HARQ The duration of sending feedback information. The delay is 3ms, TO k The preset value is 1, T first-SSB_TRP2 is the duration between the first time domain unit and the second time domain unit of TRP2, T SSB_TRP1 is the SSB period of TRP1, T SSB-proc To parse the duration of SSB, NR slot length is the length of the time domain unit.

[0262] In some embodiments, the period of the second information sent by the first TRP is smaller than the period of the second information sent by the second TRP, the second time domain unit of the second information sent by the first TRP overlaps with the second time domain unit of the second information sent by the second TRP, and a first delay is determined based on the time interval between the first time domain unit of the second TRP and the second time domain unit of the second TRP and the period of the second information sent by the first TRP. The first delay is used to indicate the total delay of activating the TCI state corresponding to the first TRP and the delay of activating the TCI state corresponding to the second TRP.

[0263] In the embodiment of the present disclosure, the period of the second information sent by the first TRP is the minimum period, and the period of the second information sent by the second TRP is the maximum period.

[0264] It should be noted that the embodiment of the present disclosure is described by taking the first TRP and the second TRP as an example. In another embodiment, if there are three or more TRPs, the above method is also used for determination.

[0265] In some embodiments, a maximum period is determined from each period of the second information; a first delay is determined based on the duration interval between the first time domain unit of the TRP corresponding to the second information corresponding to the maximum period and the second time domain unit of the TRP and the minimum period, and the first delay is used to indicate the total delay of activating the TCI state corresponding to the first TRP and the delay of activating the TCI state corresponding to the second TRP.

[0266] In some embodiments, the time interval of the second time domain unit corresponding to the maximum period is determined from the time interval between the first time domain unit and each second time domain unit in a plurality of second time domain units, and the first delay is determined based on the time interval of the second time domain unit corresponding to the maximum period and the minimum period. The first delay is used to indicate the total delay of activating the TCI state corresponding to the first TRP and the delay of the TCI state corresponding to the second TRP.

[0267] In some embodiments, the first delay is determined based on the time interval and minimum period of the second time domain unit corresponding to the maximum period, including: determining the first delay based on the time of receiving the first information, the duration of sending the feedback information, the duration of parsing the first information, the time interval and minimum period of the second time domain unit corresponding to the maximum period, and the duration of parsing the second information.

[0268] In the embodiment of the present disclosure, the activation delays of the TCI states corresponding to the first TRP and the second TRP are defined together, so it is sufficient to determine a delay for activating the TCI state, and therefore it is sufficient to determine the maximum time interval as the delay for activating the TCI state.

[0269] In the embodiment of the present disclosure, there are differences in the time when the terminal receives the first information. Therefore, it is necessary to determine the time interval between the first time domain unit and each second time domain unit in the multiple second time domain units, determine the time interval of the second time domain unit corresponding to the maximum period, and then determine the delay of the TCI state based on the time interval of the second time domain unit corresponding to the maximum period and the minimum period.

[0270] For example, referring to FIG2D , a MAC CE activates the TCI state of a TRP, where the period of SSB2 is greater than the period of SSB1, and the duration from receiving the MAC CE1 of TRP1 to receiving the first SSB1 is greater than the duration from receiving the MAC CE2 of TRP2 to receiving the first SSB2. Therefore, the sum of the duration from receiving the MAC CE2 of TRP2 to receiving the first SSB2 and the period of SSB2 is determined as the delay for activating the TCI state.

[0271] Optionally, the first information has a one-to-one correspondence with multiple TCI states, and the maximum period is determined from each period of the second information; based on the time interval between the first time domain unit of the TRP corresponding to the second information corresponding to the maximum period and the second time domain unit of the TRP and the minimum period, the first delay is determined, and the first delay is used to indicate the total delay of activating the TCI state corresponding to the first TRP and the delay of activating the TCI state corresponding to the second TRP.

[0272] Optionally, the first information has a one-to-one correspondence with multiple TCI states. The time interval of the second time domain unit corresponding to the maximum period is determined from the time interval between the first time domain unit and each second time domain unit in the multiple second time domain units. The delay of the TCI state is determined based on the time interval of the second time domain unit corresponding to the maximum period and the minimum period.

[0273] Optionally, the second time domain unit of the second information sent by the first TRP overlaps with the second time domain unit of the second information sent by the second TRP, and the maximum period is determined from the period of each of the second information; based on the time interval between the first time domain unit of the TRP corresponding to the second information corresponding to the maximum period and the second time domain unit of the TRP and the minimum period, the first delay is determined, and the first delay is used to indicate the total delay of activating the TCI state corresponding to the first TRP and the delay of activating the TCI state corresponding to the second TRP.

[0275] It should be noted that the time delay from receiving the first information to activating the TCI state can be expressed by the formula:

[0276] Wherein, n is the time of receiving the first information, THARQ The duration of sending feedback information. The delay is 3ms, TO k The preset value is 1, T first-SSB is the duration between the first time domain unit and the second time domain unit of TRP2, T SSB_TRP1 is the SSB period of TRP1, T SSB_TRP2 is the SSB period of TRP2, T SSB-proc To parse the duration of SSB, NR slot length is the length of the time domain unit.

[0278] It should be noted that the embodiment of the present disclosure is described using the first TRP and the second TRP as an example. In another embodiment, if three or more TRPs are included, the time delay of the TCI state of the TRP with the shortest period is determined based on the time interval between the first time domain unit of the TRP with the longest period and the second time domain unit of the TRP, and the period of the second information sent by the TRP with the shortest period.

[0279] In some embodiments, a maximum period is determined from each period of the second information; a third delay is determined based on the duration interval between the first time domain unit of the TRP corresponding to the second information corresponding to the maximum period and the second time domain unit of the TRP and the minimum period, and the third delay is used to indicate the delay of activating the TCI state of the TRP corresponding to the minimum period.

[0286] In the embodiment of the present disclosure, activation delays of multiple TCI states are defined separately, so it is necessary to determine the activation delay of the TCI state corresponding to each TCI state separately.

[0287] It should be noted that the time delay from receiving the first information to activating the TCI state can be expressed by the formula:

[0288] Wherein, n is the time of receiving the first information, T HARQ The duration of sending feedback information. The delay is 3ms, TO k The preset value is 1, T first-SSB T is the duration between the first time domain unit and the second time domain unit with a smaller SSB period, SSB_TRP1 is the SSB period of TRP1, T SSB_TRP2 is the SSB period of TRP2, T SSB-proc To parse the duration of SSB, NR slot length is the length of the time domain unit.

[0290] It should be noted that the disclosed embodiment is described using the first and second TRPs as examples. In another embodiment, if three or more TRPs are included, then for each TRP other than the one with the smallest period of the second information, the delay for activating the TCI state of the second TRP is determined based on the time interval between the first time domain unit of the TRP and the second time domain unit of the TRP.

[0293] In some embodiments, the time interval of the second time domain units corresponding to other periods except the second time domain unit corresponding to the maximum period is determined from the time interval between the first time domain unit and each second time domain unit in a plurality of second time domain units, and based on the time interval of the second time domain units corresponding to other periods except the second time domain unit corresponding to the maximum period, the delay of the TCI state corresponding to the second time domain units corresponding to other periods except the second time domain unit corresponding to the maximum period is determined.

[0294] Optionally, the first information has a one-to-one correspondence with multiple TCI states, and the maximum period is determined from each period of the second information; based on the time interval between the first time domain unit of the TRP corresponding to other periods except the maximum period and the second time domain unit of the TRP, the fourth delay is determined, and the fourth delay is used to indicate the delay of activating the TCI state of the TRP corresponding to the longest period.

Based on the time interval of the second time domain units corresponding to other periods except the second time domain unit corresponding to the maximum period, the delay of the TCI state corresponding to the second time domain units corresponding to other periods except the second time domain unit corresponding to the maximum period is determined.

[0296] Optionally, multiple second time domain units overlap, and the maximum period is determined from the period of each second information; based on the time interval between the first time domain unit of the TRP corresponding to other periods except the maximum period and the second time domain unit of the TRP, the fourth delay is determined, and the fourth delay is used to indicate the delay of activating the TCI state of the TRP corresponding to the longest period.

[0297] Optionally, multiple second time domain units overlap, and the time interval of the second time domain units corresponding to other periods except the second time domain unit corresponding to the maximum period is determined from the time interval between the first time domain unit and each second time domain unit in the multiple second time domain units.

[0298] In the embodiment of the present disclosure, activation delays of multiple TCI states are defined separately, so it is necessary to determine the activation delay of the TCI state corresponding to each TCI state separately.

[0299] It should be noted that the time delay from receiving the first information to activating the TCI state can be expressed by the formula:

[0307] The method for activating the TCI state involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2103. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, and step S2103 may be implemented as an independent embodiment.

[0308] In some embodiments, step S2103 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0309] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0310] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0311] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 .

[0312] FIG2E is an interactive diagram illustrating a method for activating a TCI state according to an embodiment of the present disclosure. As shown in FIG2E , the embodiment of the present disclosure relates to a method for activating a TCI state, and the method includes:

[0313] Step S2201: The network device sends at least one first information to the terminal.

[0314] In some embodiments, at least one first information is used to indicate activation of a TCI state corresponding to a first TRP and a TCI state corresponding to a second TRP.

[0315] Among them, step S2201 is similar to step S2101 in the above embodiment and will not be repeated here.

[0316] Step S2202, when the first SSB of the first TRP does not overlap with the first SSB of the second TRP, the terminal receives the first SSB corresponding to the first TRP and the second TRP respectively.

[0317] In some embodiments, the first SSB of the first TRP is the first SSB after the first information; the first SSB of the second TRP is the first SSB after the first information.

[0318] In some embodiments, the first SSB of the first TRP is the first SSB received after parsing of the first information is completed; the first SSB of the second TRP is the first SSB received after parsing of the first information is completed.

[0319] For example, referring to FIG. 2B , a MAC CE activates the TCI states of the first TRP and the second TRP, and can receive the first SSB of the first TRP and the first SSB of the second TRP, respectively.

[0320] In some embodiments, when a first information activation simultaneously indicates the activation of the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP, and the first SSB of the first TRP does not overlap with the first SSB of the second TRP, the terminal determines the first delay based on the maximum time interval between the moment when the parsing of the first information is completed and the moment when the terminal receives the first SSB of each TRP. The first delay is used to indicate the total delay of the delay in activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP.

[0321] In some embodiments, referring to FIG. 2B , one MAC CE activates the TCI states of two TRPs. The time interval of TRP1 is smaller than the time interval of TRP2 , and therefore the time interval of TRP2 is determined as the delay for activating the TCI state.

[0322] In some embodiments, the time delay from receiving the first information to activating the TCI state can be expressed as follows:

[0323] Wherein, n is the time of receiving the first information, T HARQ The duration of sending feedback information. The delay is 3ms, TOk The preset value is 1, T first-SSB_TRP1 is the duration between the first time domain unit and the second time domain unit of TRP1, T first-SSB_TRP2 is the duration between the first time domain unit and the second time domain unit of TRP2, T SSB-proc To parse the duration of SSB, NR slot length is the length of the time domain unit.

[0324] Step S2203, when the first SSB of the first TRP overlaps with the first SSB of the second TRP, the terminal receives the SSBs corresponding to each TRP according to the period of the SSB corresponding to the first TRP and the SSB period corresponding to the second TRP.

[0325] In some embodiments, when the first SSB of the first TRP overlaps with the first SSB of the second TRP, the terminal determines to receive the first SSB corresponding to the first TRP, wherein the period of the SSB corresponding to the first TRP is greater than or equal to the period of the SSB corresponding to the second TRP.

[0326] In some embodiments, after receiving the first SSB corresponding to the first TRP, the terminal receives the SSB corresponding to the second TRP.

[0327] In some embodiments, when each first information in multiple first information indicates the activation of a TCI state corresponding to a TRP, and the first SSB of the first TRP overlaps with the first SSB of the second TRP, the terminal determines the first delay based on the time interval between the moment when the parsing of the first information is completed and the moment when the first SSB of the TRP corresponding to the maximum SSB cycle is received and the minimum SSB cycle. The first delay is used to indicate the total delay of the delay of activating the TCI state corresponding to the first TRP and the TCI state corresponding to the second TRP.

[0328] Referring to Figure 2C, one MAC CE activates the TCI state of two TRPs. The SSB period of TRP1 is smaller than the SSB period of TRP2. Therefore, the sum of the duration interval between the first time domain unit and any second time domain unit among the multiple second time domain units and the minimum period is determined as the delay for activating the TCI state.

[0329] It should be noted that the time delay from receiving the first information to activating the TCI state can be expressed by the formula:

[0330] Wherein, n is the time of receiving the first information, T HARQ The duration of sending feedback information. The delay is 3ms, TO k The preset value is 1, T first-SSB_TRP2is the duration between the first time domain unit and the second time domain unit of TRP2, T SSB_TRP1 is the SSB period of TRP1, T SSB-proc To parse the duration of SSB, NR slot length is the length of the time domain unit.

[0331] In some embodiments, when each first information in multiple first information indicates the activation of a TCI state corresponding to a TRP, and the first SSB of the first TRP overlaps with the first SSB of the second TRP, the terminal determines the second delay based on the time interval between the moment when the parsing of the first information is completed and the moment when the first SSB of the TRP corresponding to the maximum SSB cycle is received, and the minimum SSB cycle. The second delay is used to indicate the delay in activating the TCI state of the TRP corresponding to the minimum SSB cycle.

[0332] In some embodiments, when each first information in multiple first information indicates the activation of a TCI state corresponding to a TRP, and the first SSB of the first TRP overlaps with the first SSB of the second TRP, the terminal determines a third delay based on the time interval between the moment when parsing of the first information is completed and the moment when the first SSB of the TRP corresponding to the maximum SSB period is received. The third delay is used to indicate the delay in activating the TCI state of the TRP corresponding to the maximum SSB period.

[0333] For example, referring to FIG2D , a MAC CE activates the TCI state of a TRP, where the period of SSB2 is greater than the period of SSB1, and the duration from receiving the MAC CE1 of TRP1 to receiving the first SSB1 is greater than the duration from receiving the MAC CE2 of TRP2 to receiving the first SSB2. Therefore, the sum of the duration from receiving the MAC CE2 of TRP2 to receiving the first SSB2 and the period of SSB2 is determined as the delay for activating the TCI state.

[0334] It should be noted that the time delay from receiving the first information to activating the TCI state can be expressed by the formula:

[0335] Wherein, n is the time of receiving the first information, T HARQ The duration of sending feedback information. The delay is 3ms, TO k The preset value is 1, T first-SSB is the duration between the first time domain unit and the second time domain unit of TRP2, T SSB_TRP1 is the SSB period of TRP1, T SSB_TRP2 is the SSB period of TRP2, T SSB-proc To parse the duration of SSB, NR slot length is the length of the time domain unit.

[0336] It should be noted that the time delay from receiving the first information to activating the TCI state can be expressed by the formula:

[0337] Wherein, n is the time of receiving the first information, T HARQ The duration of sending feedback information. The delay is 3ms, TO k The preset value is 1, T first-SSB T is the duration between the first time domain unit and the second time domain unit with a larger SSB period, SSB-proc To parse the duration of SSB, NR slot length is the length of the time domain unit.

[0394] FIG6 is a flow chart of a method for activating a TCI state according to an embodiment of the present disclosure. As shown in FIG6 , the embodiment of the present disclosure relates to a method for activating a TCI state, and the method includes:

[0395] Step S6101: The terminal determines the total TCI activation delay.

[0396] For two TRP case, the total TCI activation delay is defined based on the maximum delay required to perform TCI state switch for each TRP.For each TCI activation delay,if the TCI state is known but not in the active TCI state list,extra time and frequency tracking is needed.The extra T / F tracking delay is based on the first SSB after MAC CE command.if the two SSBs after MAC CE is not overlapped,the delay requirement is defined based on the maximum length of the two TCI state switch time as shown in Fig.1.

[0397] Fig.1 Total delay for mTRP

[0398] Therefore, the maximum delay for two TCI state switching where two SSBs are not overlapped is:

[0399] In TDM scheme, UE can only receive one SSB from one TRP by one panel at one time. After MAC CE, when the first SSBs of two TRPs are overlapped, UE can only receive one SSB.

[0400] For example, if UE receive SSB from TRP1, UE will wait for the 2 nd SSB of TRP2.The 2 nd SSB arriving time will depend on the SSB periodicity. The SSB periodicity will have impact the delay. (For example, if the UE receives an SSB from TRP1, the UE will wait for the second SSB from TRP2. The time when the second SSB arrives will depend on the SSB periodicity. The SSB periodicity will have an impact on the delay.)

[0401] Since the periodicity of two SSBs are different,the delay to process SSB will be different.Suppose the periodicity of TRP1is T SSB_TRP1 and periodicity of TRP2is T SSB_TRP2 .(Since the two SSB cycles are different, the delay in processing SSB will also be different. Let the cycle of TRP1 be TSSB_TRP1 and the cycle of TRP2 be T SSB_TRP2 )T SSB_TRP1 <T SSB_TRP2 .

[0402] As shown in Fig.2, after MAC CE command, when the overlapped two SSBs arrived, UE will skip he SSB with larger periodicity and keep SSB with smaller periodicity, i.e., UE will receive SSB1 for TRP1 and will skip SSB1 from TRP2. For TRP2, UE need to wait until the next SSB(SSB2) of TRP2.

[0403] Fig.2case 1:drop the SSB with larger periodicity

[0404] The total delay of process SSB from two TRPS will be

[0405] where T first-SSB_TRP1 is the first SSB of TRP1after MAC CE.T SSB_TRP2 is the SSB periodicity of TRP2. (Tfirst-SSB_TRP1 is the first SSB of TRP1 after MAC CE. TSSB_TRP2 is the SSB periodicity of TRP2)

[0406] However, if UE skips the SSB with smaller periodicity (first SSB of TRP1) and drop the SSB with larger periodicity, the delay will be reduced since T SSB_TRP1 <T SSB_TRP2,, as shown in Fig. 3. (However, if the UE skips the SSB with a smaller period (the first SSB of TRP1) and discards the SSB with a larger period, the delay will be reduced because TSSB_TRP1 < TSSB_TRP2, as shown in Fig. 3)

[0407] Fig. 3 case 2: drop the SSB with smaller periodicity

[0408] UE will receive first SSB from TRP2, then UE wait for receiving the 2 nd SSB from TRP1, the total delay will be reduced the total is: (UE will receive the first SSB from TRP2, then UE waits for receiving the second SSB from TRP1, and the total delay will be reduced, and the total is)

[0409] where T first-SSB_TRP1 is the first SSB of TRP2 after MAC CE. T SSB_TRP1 is the SSB periodicity of TRP1.

[0410] Delay reduction in sDCI (One command activates the two TRPs)

[0411] Therefore, when the first SSBs from two TRPs are overlapped, UE can drop the SSB whose periodicity is smaller, then UE can receive the corresponding 2 nd SSB faster. The total delay can be reduced. With the enhanced method, the total delay will be: (Therefore, when the first SSBs from two TRPs overlap, the UE can discard the SSB with a smaller period, and then the UE can receive the corresponding second SSB faster. The total delay can be reduced. Using the enhanced method, the total delay will be)

[0412] where T first-SSB is the first SSB with larger periodicity between TRPs after MAC CE command.min(T SSB_TRP1 ,T SSB_TRP2 ) is the smaller SSB periodicity between two TRPs. (Where Tfirst-SSB is the first SSB with the larger period between TRPs after the MAC CE command. min(TSSB_TRP1,TSSB_TRP2) is the smaller SSB periodicity between two TRPs.)

[0413] Delay reduction in mDCI

[0414] Similarly, the mDCI based TCI activation delay will be reduced either.For mDCI case,two separate target TCIs state will be sent from two TRPs respectively.If the two first SSBs from two TRPs are overlapped,no matter which MAC CE command arrives earlier,UE will drop the first SSB with smaller periodicity,as shown below:

[0415] Case 1: if the delay requirement is defined separately for two TRPs

[0416] For mDCI,if the delay requirement is defined separately for two TRPs,then the requirement will be as below:

[0417] The delay for TRP with smaller SSB periodicity (TRP1) will be: (For mDCI, if the delay requirements are defined for the two TRPs separately, the requirements are as follows:

[0418] The delay of TRP (TRP1) with smaller SSB period is:

[0419] where T first-SSB Tfirst-SSB is the first SSB with smaller periodicity between TRPs after MAC CE command.

[0420] The delay for TRP with larger SSB periodicity (TRP2) will be:

[0421] where T first-SSB Tfirst-SSB is the first SSB with larger periodicity between TRPs after MAC CE command.

[0422] Case 2: if total delay requirement is defined for two TRPs together

[0423] If one total delay requirement is defined for two TRPs together, the total delay is:

[0424] where T first-SSB is the first SSB with larger periodicity between TRPs after MAC CE command.min(T SSB_TRP1 ,T SSB_TRP2 ) is the smaller SSB periodicity between two TRPs. (Where Tfirst-SSB is the first SSB with the larger period between TRPs after the MAC CE command. min(TSSB_TRP1,TSSB_TRP2) is the smaller SSB periodicity between two TRPs.)
