Abstract: Methods and apparatuses for improving initialization of sidelink duplication reception in a wireless communication system are disclosed herein. In one method, a User Equipment (UE) receives a first Packet Data Convergence Protocol (PDCP) Protocol Data Unit (PDU) on a logical channel associated with a sidelink radio bearer (SLRB). The UE initializes a first state variable based on a partial Reordering_Window and a PDCP Sequence Number (SN) of the first received PDCP PDU, wherein the first state variable indicates the PDCP SN of a last PDCP Service Data Unit (SDU) delivered to the upper layers by a PDCP entity created for the SLRB, and the partial Reordering_Window is less than a Reordering_Window. The UE performs a re-ordering procedure for the first PDCP PDU using the initialized first state variable.

Abstract: Methods and apparatuses for implementing reference signal transmissions in a wireless communication system. According to one method, the UE receives a downlink transmission burst from a base station in a first unlicensed channel. The UE also receives an information in a second channel, wherein the information defines whether a subframe is an end subframe of the downlink transmission burst in the first unlicensed channel. The UE determines whether or not to receive a control message, data, or a reference signal from a next frame in the first unlicensed channel. The UE receives the control message, data, or the reference signal from the next frame in the first unlicensed channel if the information indicates that the subframe is not the end subframe of the downlink transmission burst. Alternatively, the UE refuses to receive the control message, data, or the reference signal from the next frame in the first unlicensed channel if the information indicates that the subframe is the end subframe of the downlink transmission burst.

Abstract: A method and apparatus are disclosed, from the perspective of the UE, for performing random access procedure. In one embodiment, the method includes the UE receives a first back-off information from the network in a broadcast message, wherein the first back-off information includes a start offset of back-off interval. The method further includes the UE transmits a first preamble to the network. In addition, the method includes the UE determines a back-off interval based on the first back-off information and a second back-off information, wherein the second back-off information is received when the UE monitors a response for the first preamble. The method also includes the UE transmits a second preamble to the network after the back-off interval is finished.

Abstract: A method and device are disclosed for a User Equipment (UE) to sidelink discontinuous reception (DRX) for sidelink groupcast communication associated with a group. In one embodiment, the method includes the UE assuming or considering a sidelink DRX configuration applied for the sidelink groupcast communication associated with the group, wherein the sidelink DRX configuration comprises at least one of an on-duration timer length used for determining an on-duration at the beginning of each sidelink DRX cycle and/or a cycle length used for determining a length of each sidelink DRX cycle. The method also includes the UE deriving or determining a time to start of on-duration for each sidelink DRX cycle or start of each sidelink DRX cycle based on at least an identifier associated with the group. The method further includes the UE transmitting a sidelink control information associated with the group on a sidelink control channel in a period, wherein the period is determined based on the SL DRX configuration and the time to start of on-duration for each sidelink DRX cycle or start of each sidelink DRX cycle.

Abstract: In an example, a User Equipment (UE) receives and/or detects a transmission of data from a network. The transmission of the data is addressed to a Group Radio Network Temporary Identifier (G-RNTI) for a Hybrid Automatic Repeat Request (HARQ) process. In response to receiving and/or detecting the transmission of the data, the UE (i) starts a first HARQ Round Trip Time (RTT) timer associated with the G-RNTI for the HARQ process, and (ii) starts a second HARQ RTT timer associated with a Cell Radio Network Temporary Identifier (C-RNTI) for the HARQ process. The UE starts a multicast retransmission timer for the HARQ process in response to expiry of the first HARQ RTT timer. The UE starts a unicast retransmission timer for the HARQ process in response to expiry of the second HARQ RTT timer. The UE receives and/or detects a first retransmission of the DL data addressed to the G-RNTI for the HARQ process. In response to receiving and/or detecting the first retransmission of the data, the UE (i) stops the multicast retransmission timer, and (ii) stops the unicast retransmission timer.
