In step S2201, the network device sends at least one first information to the terminal.

In some embodiments, the at least one first information is used to indicate that the TCI state corresponding to the first TRP is activated and the TCI state corresponding to the second TRP is activated.

Step S2201 is similar to step S2101 in the above embodiment, and is not described herein.

wherein n is the time of receiving the first information, T _HARQ In order to transmit the duration of the feedback information, For a delay of 3ms, TO _k For a preset value of 1, T _{first-SSB_TRP2} For the duration between the first time domain unit and the second time domain unit of TRP2，T _{SSB_TRP1} Period of SSB, T, which is TRP1 _SSB-proc For resolving the duration of SSB, NR slot length is the length of the time domain unit.

In some embodiments, when each of the plurality of first information indicates that the TCI state corresponding to one TRP is activated, and the first SSB of the first TRP overlaps with the first SSB of the second TRP, the terminal determines a second delay based on a duration interval between a time when parsing the first information is completed and a time when receiving the first SSB of the TRP corresponding to the maximum SSB period and the minimum SSB period, the second delay being used to indicate a delay for activating the TCI state of the TRP corresponding to the minimum SSB period.

In some embodiments, when each of the plurality of first information indicates that the TCI state corresponding to one TRP is activated, 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 a duration interval between a time when parsing the first information is completed and a time when the first SSB of the TRP corresponding to the maximum SSB period is received, the third delay being used to indicate a time delay for activating the TCI state of the TRP corresponding to the maximum SSB period.

In step S6101, the terminal determines the total TCI activation delay.

For two TRP cases, 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 (For two TRP cases, the total TCI activation delay is defined in terms of the maximum delay required For each TRP to perform a TCI state switch

Fig.1total delay for mTRP

Thefecore the maximum delay for two TCI state switching where two SSBs are not overlapped is (thus, when two ssbs do not overlap, the maximum delay of two TCI state switches is:)

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. (In TDM scheme, UE can only receive one SSB of one panel from one TRP at a time, after MAC CE, UE can only receive one SSB when the first SSB of two TRP overlaps

For example,if UEreceive 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 (e.g., if the UE receives an SSB from TRP1, the UE will wait for the second SSB of TRP2. The time for the second SSB to arrive will depend on the period of the SSB. The periodicity of the SSB will have an effect on delay.)

Since the periodicity of two SSBs are different,the delay to process SSB will be different.Suppose the periodicity of TRP1 is T _{SSB_TRP1} and periodicity of TRP2 is T _{SSB_TRP2} (the delay in handling SSB will be different due to the different periods of the two SSB. Let TRP1 have a period of TSSB_TRP1 and TRP2 have a period of T _{SSB_TRP2} )T _{SSB_TRP1} <T _{SSB_TRP2.}

As show in fig.2, after MAC CE command, when the overlapped two SSB arrived, UE will skip he SSB with larger periodicity and keep SSB with smaller periodicity, i.e., UE will receive SSB for TRP1 and will skip SSB1 from TRP2 for TRP2, UE need to wait until the next SSB (SSB 2) of TRP2 (As shown in fig.2, after a MAC CE command, when two overlapping SSBs arrive, the UE skips SSBs with larger period, retains SSBs with smaller period, i.e., the UE receives SSB1 of TRP1, skips SSB1 from TRP2.For TRP2, the UE needs to wait for the next SSB (SSB 2) of TRP2.

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

The total delay of process SSB from two TRPS will be (the total delay of the process SSB of two TRPS will be

where T _{first-SSB_TRP1} is the first SSB of TRP1 after MAC CE.T _{SSB_TRP2} is the SSB periodicity of TRP2 (wherein TfirstSSB_TRP1 is the first SSB.TSSB_TRP2 of TRP1 after MAC CE is the SSB period of TRP 2)

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 show in fig.3 (however, if the UE skips the less periodic SSB (the first SSB of TRP 1), discards the more periodic SSB, then due to tssb_trp1<TSSB_TRP2, delay is reduced as shown in FIG.3

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

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 and then UE waits for the second SSB from TRP1, the total delay will decrease, totaling

where T _{first-SSB_TRP1} is the first SSB of TRP2 after MAC CE.T _{SSB_TRP1} is the SSB periodicity of TRP1.

Delay reduction in sDCI (one command to activate two TRPs)

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 master total delay can be reduced. With the enhanced method, the total delay will be (so that when the first SSBs from two trps overlap, the UE can discard SSBs with smaller periods, then the UE can receive the corresponding second SSB faster.) the total delay can be reduced using the enhanced approach, the total delay will be

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 a larger period between trps after a MAC CE command. min (TSSB_TRP1, TSSB_TRP2) is the smaller SSB period between two TRP

Delay reduction in mDCI

Similarly, TCI activation delay based on mDCI will also decrease for the mDCI case, two separate target TCI states will be sent from two trp separately for the mDCI case, if the first two SSBs of the two trp overlap, whichever MAC CE command arrives earlier, the UE will discard the first SSB with less period, as shown in the following figure

Case1: if the delay requirement is defined separately for two TRPs (love) Condition 1 if two trp define delay requirements respectively

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

The delay for TRP with smaller SSB periodicity (TRP 1) will be (for mDCI, if delay requirements are defined for two TRP respectively, the requirements are as follows:

the delay of TRP (TRP 1) with smaller SSB period is:)

where T _first-SSB is the first SSB with smaller periodicity between TRPs after MAC CE command (where TfirstSSB is the first SSB with smaller period between trp after the MAC CE command)

The delay for TRP with larger SSB periodicity (TRP 2) will be (delay of TRP (TRP 2) with larger SSB period is:)

/>

where T _first-SSB is the first SSB with larger periodicity between TRPs after MAC CE command (where TfirstSSB is the first SSB with a larger period between trp after the MAC CE command)

Case2: if total delay requirement is defined for two TRPs together (love) Condition 2 if two trp together define the total delay requirement

if one total delay requirement is defined for two TRPs together, the total delay is (if a total delay requirement is defined for two trp together, the total delay is:)
