To facilitate an understanding of the disclosed embodiments, an exemplary embodiment is provided.

In an exemplary embodiment, for mTRP cases, multiple TCI states will be activated. These TCI states may be activated in one MAC CE (sdi) or in a separate MAC CE (mdi).

In some embodiments, for mTRP, there are different transmission schemes: the multiple panels receive simultaneously or the single panels receive asynchronously.

In some embodiments, for simultaneous reception, two signals from two TRPs will be received simultaneously. For non-simultaneous reception, the UE will apply one panel to receive signals from two TRPs in a TDM fashion. Different transmission schemes have different known conditions for the TCI state to be activated in the MAC CE command.

In the disclosed embodiments, known conditions for TCI activation of mTRP need to be defined. The impact of group-based reporting needs to be considered and the dual TCI state-known conditions based on sdi cannot be directly applied to mci.

In some embodiments, the known conditions for two TCI states received non-simultaneously:

for non-simultaneous reception in FR2, such as a TDM scheme. The two TCI states will be used to receive data from the two TRPs in a TDM fashion. For example, a terminal will receive data from TRP1 of slot 1 and data from TRP2 of slot 2. The two TCI states are independent and known conditions may be defined for each TCI state separately. The known conditions already only consider the L1-RSRP report. Here, the TCI status to be activated in the MAC CE may be reported in a group-based report. Thus, in addition to the traditional L1 RSRP report, group-based reporting is also considered a known condition for a single TCI state.

In some embodiments, the known condition of a single TCI state will be updated as:

during a period from a last transmission of an RS resource for an L1-RSRP measurement report of a target downlink TCI state to completion of an active downlink TCI state handover, wherein the RS resource for the L1-RSRP measurement is an RS in the target downlink TCI state or QCL to the target downlink TCI state;

the downlink TCI state switch command is received within 1280 ms after the last transmission of the RS resource for beam reporting or measurement;

at least 1L 1-RSRP report or group-based report has been sent for the target downlink TCI state prior to the downlink TCI state switch command;

during the downlink TCI state switching, the target downlink TCI state is still detectable;

during a downlink TCI handoff, SSBs associated with the downlink TCI state are still detectable;

the signal to noise ratio of the downlink TCI state is more than or equal to-3 dB;

the SSB may be associated with a serving cell PCI or with a PCI different from the serving cell PCI.

In some embodiments, the known conditions for two TCI states received simultaneously:

for simultaneous reception in FR2, two panels are required for a TCI state switch based on MAC CE. Each panel receives data from one TRP, and the network device needs to activate or switch two TCI states through both panels in order for the terminal to better receive signals from both TRPs. Before the TCI state pair changes, the terminal needs to perform L1-RSRP on both TRPS and report the best beam pair in a group-based report. In a group-based report, the two TCI states associated with the best beam pair will inform the network device. Later the network device will configure the TCI state pair to the terminal.

The known conditions for simultaneous reception are based on the definition of the FR2 group-based report as follows:

the dual TCI state is known if the following conditions are met:

the dual TCI state is QCL, and within a group is the D-type to reported beam pair (i.e., RS resource pair);

during the TCI state switch, all RSs in the dual TCI state and both QCL chains remain detectable;

the signal to noise ratio of the TCI state is more than or equal to-3 dB;

RS resource pairs configured for dual TCI state are reported in the last [1280] ms.

In some embodiments, the known condition for the dual TCI state of mci:

for mci based TCI activation, two separate MAC CEs will be sent to the terminal. For each MAC CE, only one TCI state will be activated in one command. Each MAC CE activation will be handled separately. The known conditions for simultaneous reception can only be defined for one TCI state, since there is only one TCI state in each MAC CE. The known conditional double TCI state of sdi cannot be directly applied to the mdis scheme.

Assume that two TCI states in two MAC CEs are:

case 1: { TCI state 1 in MAC CE1 in group-based report, TCI state 2 in MAC CE2 is not in group-based report }.

Case 2: { TCI state 1 in MAC CE1 in group-based report, TCI state 2 in MAC CE2 in group-based report }.

The known state of TCI state 1 cannot be determined by MAC CE 1 alone. Case 1 is unknown and case 2 is known.

Since the TCI state differs in the delay requirement for the known case and the unknown case, the known condition will have an impact on the delay requirement for each TRP.

In some embodiments, for the known conditions of mdis, there are two possible solutions:

solution 1: the independent assumption remains in mdis, known conditional solution 2 defining a single TCI state in one MAC CE: the independent hypotheses in the mdis are deleted and known conditions are defined for the two MAC CEs together.

In some embodiments, for solution 1, the known condition is still defined based on a single TCI, but the report will change to a group-based report.

In some embodiments, for solution 2, a certain relationship may also be created between two MAC CEs, and two TCI states are considered simultaneously, then the double TCI state-known condition may be reused. It is therefore necessary to define conditions on how to link two separate TCI states together to instruct two MAC CE activations for multiple panels to receive simultaneously. There are several options to define the conditions:

option 1: depending on the timing offset between the two MAC CEs.

For option 1, if the timing offset between two MAC CEs is small, we can assume that the two TCI states are considered together. It is well known that for simultaneous reception in mTRP, it requires that the timing offset between two TRPs is small and that both TRPs function well. If two MAC CEs arrive within [ x ] ms, the UE may combine the two target TCI states into a pair and consider them.

Option 2: depending on the group-based reporting.

Two MAC CEs from mTRP may be considered as a pair if a group-based report was previously reported.

Option 3: depending on whether the UE sends a multi-RX indication back to the NW. Illustratively, the multiple RX indication is the first indication information in the above embodiments.

If the UE sends a multiple RX indication with "YES" to the NW before the MAC CE command. If it indicates current, the UE acknowledges simultaneous reception. Then the two MAC CEs received from mTRP may be considered as a pair.

Option 4: the NW sends an indication of Multi-RX to the UE. Illustratively, the indication about Multi-RX is the second indication information in the above-described embodiment.

If the NW sends an indication to the UE, the UE will receive signals from both TRPs at the same time. Then two MAC CEs may be considered as a pair.

Option 5: depending on the combination of options 1, 2, 3, 4.

In practice, only option 1 or option 2 cannot guarantee that two TCI states are used for simultaneous reception. As for option 1, in the TDM scheme of mTRP, two MAC CEs may be received for activating TCI. Therefore, at least two of options 1, 2, 3, 4 are preferably used simultaneously.

In some embodiments, the known conditions for FR 1: for simultaneous reception of FR1, the dual TCI state will not involve QCL-type and will not be reported in the form of beam pairs. Since it is used for beam pair reporting, it is only used for FR2. Therefore, the known condition for simultaneously receiving FR1 is different from FR2. For FR1, the two TCI states are measured and reported separately. Thus, the known conditions can only be defined for each TCI state separately.
