The disclosure provides method for configuring transmission configuration indicator (TCI) states for user equipment (UE) and UE. In the embodiments of the disclosure, the details about how to exactly use the TCI-based structure for indicating a common beam for various purposes (e.g., both DL/UL, UL (only) or DL (only)) have been introduced. In addition, the embodiments of the disclosure have proposed the exact behavior of switching different TCI state for different purpose as well. Accordingly, efficient beam indication for both DL/UL transmission, UL only transmission, and DL only transmission can be facilitated, and the procedure(s) related to seamlessly switching among different beam indication signaling are also specified.

Method for configuring TCI states for UE and UE using the same

A method of a non-terrestrial network (NTN) assistance information update procedure for a user equipment (UE) is provided. The method includes receiving, by the UE from a first cell, first NTN assistance information associated with the first cell; and performing, by the UE, the NTN assistance information update procedure based on at least one of UE-specific control signaling or an NTN-specific system information block (SIB) by which the UE receives the first NTN assistance information.

A wireless communication method, a User Equipment (UE), and a Base Station (BS) for performing repetition-based Uplink (UL) transmissions are provided. The wireless communication method includes receiving, from the BS, a Radio Resource Control (RRC) message including first information indicating a repetition type, second information indicating a plurality of Transmission Configuration Indicator (TCI) states, and third information including a plurality of items each configuring a Physical Uplink Shared Channel (PUSCH) resource allocation; receiving Downlink Control Information (DCI) that indicates one of the plurality of items; determining a set of nominal PUSCH repetitions; and transmitting at least one actual PUSCH repetition that is determined based on the set of nominal PUSCH repetitions, wherein each nominal PUSCH repetition in the set of nominal PUSCH repetitions maps to one of the plurality of TCI states.

Wireless communication method and User Equipment for performing repetition-based Uplink transmissions

A method of configuring a set of active cells among neighboring cells to reduce latency and interruption for inter-cell mobility is proposed. The set of active cells is an active set of cells among which UE can do fast cell switching. The set of active cells is configured by the network based on UE measurement report or network deployment information. UE maintains the configuration and can perform pre-synchronization to the configured active cells in downlink (DL) only or in both DL and uplink (UL). UE maintains the DL/UL synchronization with the active cells, and applies configuration once UE is indicated to switch to an active cell as the target cell. Because UE maintains the configuration and DL/UL timing of the target cell before receiving the cell-switch command, the mobility latency and interruption time for inter-cell mobility is reduced.
