Abstract: Methods and apparatuses of beam failure recovery via random access procedure in a wireless communication system are disclosed herein. In one method, a user equipment (UE) initiates a beam failure recovery procedure when beam failure is detected based on a beam failure indication. The UE initiates a random access procedure, wherein the random access procedure is a contention-based random access procedure and initiated based on the beam failure indication. The UE considers the beam failure recovery procedure successfully completed based on completion of the random access procedure.

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.

Abstract: A method for a wireless communications system is disclosed. In one example, a network node transmits an indication to a UE to enable or disable UE beamforming. The indication also serves to initiate a random access procedure. The indication is transmitted together with other information. The other information can include configuration information related to random access. The indication and the other information can be provided via the same RRC message. The UE initiates a random access procedure in response to receiving the indication.

Abstract: A method and apparatus are disclosed from the perspective of an User Equipment (UE). In one embodiment, the method includes the UE deriving a first pathloss value from a first pathloss reference of a serving cell, wherein the first pathloss value is used for deriving a power headroom value included in a first power headroom report. The method also includes the UE deriving a second pathloss value from a second pathloss reference of the serving cell after deriving the first pathloss value, wherein the second pathloss reference is used for power control for a first Physical Uplink Shared Channel (PUSCH) transmission on the serving cell. The method further includes the UE deriving the pathloss change based on the first pathloss value and the second pathloss value. In addition, the method includes the UE determining whether a second power headroom report is triggered based on whether the pathloss change is more than a threshold.

Abstract: Method and apparatus for handling upon UL timing asynchronism in a wireless communication system are disclosed herein. The user equipment (UE) maintains a timing advance (TA) value for each of a plurality of beams used for uplink transmissions to a cell, or a transmitter/reception point (TRP) operatively connected to a gNodeB. If less than all of the maintained TA values become invalid, then the UE will continue transmission on any beam for which the TA value remains valid, while discontinuing transmission on any beam with an invalid TA value.
