Abstract: Methods and apparatuses for releasing preconfigured uplink resources configuration in a wireless communication system are disclosed herein. In one method, a User Equipment (UE) receives a configuration of a preconfigured uplink resource (PUR) when the UE is in a first RRC_CONNECTED state. The UE enters a first RRC_IDLE state from the first RRC_CONNECTED state. The UE performs a first transmission using the PUR when the UE is in the first RRC_IDLE state. The UE enters a second RRC_CONNECTED state from the first RRC_IDLE state. The UE suspends the configuration when the UE is in the second RRC_CONNECTED state. The UE resumes the configuration when the UE enters a second RRC_IDLE state from the second RRC_CONNECTED state. The UE performs a second transmission using the PUR when the UE is in the second RRC_IDLE state.

Abstract: A method and apparatus are disclosed from the perspective of a User Equipment (UE). In one embodiment, the method includes receiving, from a network node, a configuration of Preconfigured Uplink Resources (PUR), when the UE is in RRC_CONNECTED state, wherein the PUR is used for a transmission when the UE is in RRC_IDLE state. The method also includes determining to generate a first Radio Resource Control (RRC) message or a second RRC message for the transmission based on whether the transmission is to be transmitted using the PUR or not, wherein the first RRC message includes a UE identity and the second RRC message does not include the UE identity. The method further includes performing the transmission including the first RRC message or the second RRC message when the UE is in RRC_IDLE state.

Abstract: A method and apparatus are disclosed from the perspective of a first node supporting wireless access and wireless backhaul. In one embodiment, the method includes the first node transmitting a first message to a second node, for updating a second routing path maintained by the second node.

Abstract: A method and apparatus are disclosed. In an example, a first node may trigger a scheduling request (SR) based upon an expected transmission from a second node which is a child node of the first node. The first node may determine a first SR configuration for the SR from a plurality of SR configurations configured to the first node.

Abstract: A method and apparatus are disclosed from the perspective of a UE (User Equipment). In one embodiment, the method includes the UE initiating a Random Access (RA) procedure on a Serving Cell, wherein the UE has multiple active uplink bandwidth parts (UL BWP) for the Serving Cell. The method further includes the UE selecting a UL BWP from the multiple active UL BWPs for an Msg1 transmission, based on a first rule. The method also includes the UE transmitting the Msg1 on the selected UL BWP.

Abstract: Methods and apparatuses of handling a bandwidth part (BWP) inactivity timer during a Random Access procedure in a wireless communication system are disclosed herein. In one method, a user equipment (UE) starts a BWP timer for a serving cell operating in a paired spectrum. The UE initiates a contention-based Random Access (RA) procedure on the serving cell and stops the BWP timer. The UE starts the BWP timer upon successful completion of the RA procedure, wherein the UE considers the contention-based RA procedure successfully completed if a Physical Downlink Control Channel (PDCCH) addressed to a Cell Network Temporary Identifier (C-RNTI) of the UE is received and the PDCCH contains an uplink grant for a 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 generating a system information request message. The method further includes the UE transmitting the system information request message to a base station through DCCH (Dedicated Control Channel) if the UE is in RRC_CONNECTED state. The method also includes the UE transmitting the system information request message to the base station through CCCH (Common Control Channel) if the UE is not in RRC_CONNECTED state.

Abstract: A method and apparatus are disclosed from the perspective of a UE (User Equipment). In one embodiment, the method includes transmitting a Scheduling Request (SR) on a first uplink bandwidth part (BWP). The method further includes receiving a response for the SR on a first downlink BWP. The method also includes detecting a beam failure when using the first uplink BWP and the first downlink BWP. In addition, the method includes transmitting a beam failure recovery (BFR) request to a network node on the first uplink BWP. Furthermore, the method includes receiving a control signalling on a second downlink BWP from the network node after transmitting the BFR request, wherein the control signalling is a response for the BFR request and the second downlink BWP is associated with the first uplink BWP.

Abstract: A method and apparatus are disclosed from the perspective of a User Equipment (UE), wherein the UE is configured with multiple Bandwidth Parts (BWPs). In one embodiment, the method includes the UE receiving information from a network node to associate a RACH (Random Access Channel) configuration with a BWP among the multiple BWPs. The method further includes that the UE performing a RACH transmission in the BWP using the RACH configuration associated with the BWP.

Abstract: A method and apparatus are disclosed from the perspective of a UE. In one embodiment, the method includes triggering a first SR by a first LCH, wherein the first LCH is associated with a first SR configuration. The method also includes triggering a second SR by a second LCH while the first SR is pending, wherein the second LCH is associated with a second SR configuration, and the first SR configuration and the second SR configuration are configured for the same serving cell. The method further includes using a first SR opportunity and a second SR opportunity to transmit SRs to a network node until the SRs are cancelled, wherein the first SR opportunity corresponds to the first SR configuration and the second SR opportunity corresponds to the second SR configuration.
