    Abstract: Methods, systems, and apparatuses are provided for mobile terminated small data transmission in a wireless communication system. A User Equipment (UE) can apply Downlink (DL) Semi Persistent Scheduling (SPS) in a Mobile Terminated Small Data Transmission (MT-SDT) procedure. The UE can handle the configured DL assignment for DL SPS. A method for a UE in a wireless communication system can comprise receiving one or more configurations of DL SPS for Radio Resource Control Inactive (RRC_INACTIVE) state, initiating a MT-SDT procedure in response to receiving a paging indicating MT-SDT, receiving, in RRC_INACTIVE state, one or more DL transmissions using a configured DL assignment for the DL SPS during the MT-SDT procedure, and keeping the one or more configurations of the DL SPS and entering RRC_CONNECTED state in response to receiving a RRC resume message during the MT-SDT procedure.

    Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE receives, via a Radio Resource Control (RRC) message, a resource configuration of a first configured grant to be used in RRC inactive state. The UE performs a first new transmission using the first configured grant in RRC inactive state. After the performing the first new transmission, the UE receives an uplink grant in RRC inactive state via Physical Downlink Control Channel (PDCCH). The UE determines whether the uplink grant is for performance of a second new transmission or for performance of a first retransmission. The UE performs the second new transmission using the uplink grant in RRC inactive state if the UE determines that the uplink grant is for performance of the second new transmission.

    Abstract: A method and apparatus are disclosed from the perspective of a UE (User Equipment). In one embodiment, the method includes the UE receiving a first MAC-CE (Medium Access Control-Control Element) including or indicating a plurality of TCI (Transmission Configuration Indication) state IDs (Identities) to be activated for receiving PDSCH (Physical Downlink Shared Channel), wherein format of the first MAC-CE depends on amount of the plurality of TCI state IDs. The method further includes the UE activating a plurality of TCI states associated with the plurality of TCI state IDs included or indicated in the first MAC-CE for receiving the PDSCH in response to reception of the first MAC-CE.

    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.
