Abstract: A method and apparatus for implementing reference signal transmissions in a wireless communication system. In one embodiment, the method includes the cell, transmission point (TP), or transmission and reception point (TRP) broadcasting a first RS periodically for measurement, wherein the first RS is transmitted at multiple occasions (or timings) in each period on different beams. The method also includes the cell, TP, or TRP transmitting a second RS to a UE for PDCCH demodulation, wherein the second RS is transmitted on multiple beams in a beam set of the UE in a subframe (or symbol) in which the PDCCH is transmitted.

Abstract: Methods and apparatuses for transmission or reception using beamforming in a wireless communication system are disclosed herein. In one method, a user equipment receives a second signal indicating a first information. The UE derives at least one specific UE beam based on the first information. The UE uses the at least one specific UE beam to receive or transmit at least one transmission, in which the at least one transmission is periodic channel state indication, scheduling request, and/or scheduling information for downlink assignment or uplink resource.

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: 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 a Random Access Channel (RACH) configuration from a network node, wherein the RACH configuration indicates at least one Physical Random Access Channel (PRACH) resource for beam failure recovery. The method further includes receiving a timing advance command from the network node, and starting or restarting a time alignment timer when receiving the timing advance command. The method also includes releasing the at least one PRACH resource for the beam failure recovery indicated by the RACH configuration when the timing alignment timer expires.

Abstract: Method and apparatus for a user equipment (UE) operating in a serving cell is disclosed. The UE, in a first RRC_CONNECTED state, transmits an interest indication for a broadcast or a multicast service to a first serving cell. The interest indication includes at least some information associated with a broadcast or a multicast service. Upon entering a second RRC_CONNECTED state from an RRC_INACTIVE state, the UE may or may not send an interest indication to a second serving cell, taking into account the differences between the first and second serving cell, whether the second serving cell requested transmission of an interest indication, or whether the content of the second interest indication would be the same as the content of the first interest indication. A network node may retain UE context and other UE-related information after the UE has left an RRC_CONNECTED state, forward the information to another network node, and/or process the information when the UE re-enters the RRC_CONNECTED state.

Abstract: Methods and apparatuses for handling transmission during a random access procedure are disclosed herein. In one method, the UE initiates a random access (RA) procedure. The UE receives a RA response during the RA procedure, wherein the RA response indicates a first uplink (UL) grant for the UE to perform a Msg3 transmission by a specific hybrid automatic repeat request (HARQ) process. The UE receives a second UL grant for the UE to perform a specific transmission, wherein the specific transmission is to be performed during the RA procedure. The UE determines whether to perform the specific transmission based on at least whether the specific transmission is to be performed by the specific HARQ process used for the Msg3 transmission, wherein the Msg3 transmission and the specific transmission are not overlapped in a time domain.

Abstract: In one example, user equipment (UE) maintains one or multiple serving beams, and uses a serving beam to perform an uplink (UL) transmission of data. The data is stored in an uplink hybrid automatic repeat request (UL HARQ) buffer. When there is a failure to track the one or multiple serving beams, a beam recovery procedure is initialized. After successful completion of the beam recovery procedure, the UE retransmits the data stored in the UL HARQ buffer. The UE prevents the data from being flushed from the UL HARQ buffer when the failure to track the one or multiple serving beams occurs, so that the data can be retransmitted.
