    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 selecting beam for preconfigured uplink resources in a wireless communication system are disclosed herein. In one method, a user equipment (UE) receives, from a network node, a signaling to configure at least one Preconfigured Uplink Resource (PUR) associated with one or more beams from multiple beams. The UE selects a first beam from the multiple beams and performs a transmission of data in RRC_INACTIVE state using the at least one PUR via the first beam if the first beam fulfills at least one condition, wherein the at least one condition comprises that the first beam is associated with the at least one PUR and Reference Symbol Received Power (RSRP) of the first beam is better than a first threshold. The UE initiates a Random Access (RA) procedure and performs the transmission during the RA procedure if no beam of the multiple beams fulfills the at least one condition.

    Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE keeps a dedicated Preconfigured Uplink Resources (PUR) configuration when the UE is in Radio Resource Control (RRC) idle state and a serving cell of the UE is a second cell, wherein the UE is configured with the dedicated PUR configuration in a first cell different than the second cell. The UE selects a third cell during a RRC connection re-establishment procedure. In response to the selecting the third cell, the UE determines whether or not to release the dedicated PUR configuration based upon whether or not the third cell is the same as the first cell, wherein the determining whether or not to release the dedicated PUR configuration is performed when the UE is in RRC connected state.
