    Abstract: Methods, systems, and apparatuses are provided for User Equipment (UE) Timing Advance (TA) reporting in a wireless communication system. The UE can appropriately trigger the TA report with the different configurations by system information (e.g., for Random Access (RA) procedure, for TA report during RA, etc.) and dedicated signaling (e.g., for Radio Resource Control (RRC) connected mode, for event-triggered TA report, etc.). A method for a UE in a wireless communication system can comprise receiving a first configuration of TA report, receiving a second configuration of TA report, and determining whether to trigger a second TA report upon receiving the second configuration based on whether a first TA report has been transmitted to a serving cell.

    Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE initiates a first Early Data Transmission (EDT) in RRC_INACTIVE state. Responsive to initiating the first EDT, the UE initiates a Random Access (RA) procedure in a cell configured with a normal uplink (NUL) carrier and a supplementary uplink (SUL) carrier. The UE selects the SUL carrier or the NUL carrier for performing the RA procedure based on at least one of whether there are one or more available Physical Random Access Channel (PRACH) resources for EDT on the SUL carrier or whether there are one or more available PRACH resources for EDT on the NUL carrier.

    Abstract: A method for a wireless communications system is disclosed. In one example, user equipment (UE) (e.g. a mobile phone) receives an indication from a network (for example, by way of a transmission and reception point (TRP)) indicating whether a first transmission and a second transmission to the UE can be combined for decoding. The UE also receives the first transmission via a first UE beam and the second transmission via a second UE beam. The first transmission and the second transmission are received concurrently. The first and second transmissions can arrive via different serving beams and/or different TRPs of the same cell. Based on the indication, the UE combines the first and second transmissions for decoding purposes.

    Abstract: Methods and apparatuses for triggering a beam state information report by a user equipment in a wireless communication system are disclosed herein. In one method, a user equipment measures multiple beam reference signals of non-serving beams from a cell and derives multiple values from measurements. The UE derives a first value, wherein the first value is a highest value, a lowest value, or an average value of the multiple values. The UE triggers to report a measurement result for a beam reference signal if at least one condition is satisfied, wherein the condition is based on comparing the first value to a threshold.
