    Abstract: Methods and apparatuses are provided for a User Equipment (UE) to determine the value of a parameter, such as a timeToTrigger, a reportOnLeave, a useWhiteCellList, etc., when the measurement reporting procedure is associated with multiple triggering events. For example, a UE can receive a measurement configuration comprising a combined triggering condition of a first triggering event and a second triggering event, trigger a first measurement report in response to fulfilment of an entering condition of the first triggering event and an entering condition of the second triggering event, and trigger a second measurement report in response to fulfilment of one of a leaving condition of the first triggering event and a leaving condition of the second triggering event, if at least a first parameter for the first triggering event or for the second triggering event is set to TRUE.

    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 device are disclosed from the perspective of a User Equipment (UE). In one embodiment, the method includes the UE receiving a first Physical Downlink Control Channel (PDCCH)-related configuration in system information. The method further includes the UE initiating a Small Data Transmission (SDT) procedure in RRC_INACTIVE state, wherein the SDT procedure comprises a Random Access (RA) procedure and at least one subsequent transmission after the RA procedure. The method also includes the UE monitoring PDCCH, based on the first PDCCH-related configuration, during the RA procedure in RRC_INACTIVE state. In addition, the method includes the UE monitoring the PDCCH, based on a second PDCCH-related configuration, for the at least one subsequent transmission in RRC_INACTIVE state if the second PDCCH-related configuration is received by the UE.

    Abstract: A method and apparatus are disclosed from the perspective of a UE (User Equipment). In one embodiment, the method includes the UE receiving an SCell activation/deactivation MAC (Medium Access Control) control element to activate the SCell. The method further includes the UE activates the SCell based on the SCell activation/deactivation MAC control element. The method also includes the UE receiving a beam indication by a MAC control element via the PCell, wherein the beam indication includes a cell index and the beam indication is used to derive at least one beam to be used in the SCell. In addition, the method includes the UE using the at least one beam for a DL (Downlink) transmission or an UL (Uplink) transmission in the SCell.
