Abstract: A method and device are disclosed from the perspective of a User Equipment (UE). The method includes the UE receiving a configuration, from a network node, indicating that Random Access Channel (RACH) occasion(s) of a first Random Access (RA) type are not configured. The method further includes the UE determining if RACH occasion(s) of the first RA type are shared with a second RA type or a third RA type, and/or includes the UE determining the starting point of preambles for the first RA type based on at least RA parameter(s) for more than one RA type.

Abstract: A method and device are disclosed from the perspective of a User Equipment (UE). In one embodiment, the method includes the UE initiating a 2-step Random Access (RA) procedure including Uplink (UL) data in RRC_INACTIVE state. The method further includes the UE switching from the 2-step RA procedure to a 4-step RA procedure not including the UL data in response to a condition.

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: To perform successful transmission using Preconfigured Uplink Resources (PUR) in RRC_IDLE state, the UE (User Equipment) should maintain a valid timing adjustment (or timing alignment, TA). Currently the maximum of TA timer (excluding infinity value) is 10.24 seconds. In many or most cases, the TA timer will expire before the next PUR occasion occurs, resulting in the UE being unable to perform transmission using PUR. To solve such issue, the UE could apply different length for the TA timer in RRC_IDLE state. A method and apparatus are disclosed from the perspective of a User Equipment (UE). In one embodiment, the method includes the UE receiving a configuration of a first timer indicating a first length in a RRCConnectionRelease message, wherein the first timer is used to control validity of a first Timing Adjustment (TA) for a transmission using Preconfigured Uplink Resources (PUR) in RRC_IDLE state. The method also includes the UE considering the first TA as invalid in response to initiating a Random Access (RA) procedure while the UE is in the RRC_IDLE state.

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: Methods and apparatuses for random access procedures for a system information request in a wireless communication system are disclosed herein. In one method, a user equipment (UE) initiates a random access procedure to request a system information. The UE transmits a random access preamble during the random access procedure. The UE monitors a control channel for a random access response immediately after transmitting the random access preamble for a request of the system information.
