The present application provides a method and device for sidelink wireless communications. A first node receives a first signaling via an air interface; as a response to receiving the first signaling, transmits a first radio signal, the first radio signal comprises a second signaling; receives a second data unit set via an air interface; herein, the second signaling indicates that a first data unit set is not received, and both the first data unit set and the second data unit set are transmitted through a first radio bearer; the second signaling is used to determine the second data unit set; a transmitter of the first signaling is non-co-located with a receiver of the first radio signal; the first data unit set comprises at least one data unit; the second data unit set comprises the first data unit set. The present application can effectively reduce data retransmission.

According to certain embodiments, a method performed by a wireless device for paging occasion (PO) allocation is provided. The method includes determining that a PO configured for the wireless device in a Discontinuous Reception (DRX) cycle is problematic. A non-problematic PO is selected based on one or more criteria. One or more paging messages are monitored for during the selected non-problematic PO.

The present invention discloses a method for a base station to transmit a radio link monitoring-reference signal (RLM-RS) in an unlicensed band. In particular, the method may divide a frequency band for the RLM-RS into a plurality of sub-bands, perform a channel clearance assessment (CCA) for each of the plurality of sub-bands, and transmit the RLM-RS via each of the plurality of sub-bands on the basis of the result of performing the CCA.

Embodiments of a system and method for providing DRX enhancements in LTE systems are generally described herein. In some embodiments, a system control module is provided for controlling communications via a communications interface. A processor is coupled to the system control module and is arranged to implement an inactivity timer and an on-duration timer for determining an active time for monitoring subframes on the physical downlink control channel for control signals, the processor further monitoring subframes after the active time.

Disclosed are techniques for determining a position of a user equipment (UE). A differential round-trip-time (RTT) based positioning procedure is proposed to determine the UE position. In this technique, the UE position is determined based on the differences of the RTTs between the UE and a plurality of base stations. The differential RTT based positioning procedure has much looser inter-gNodeB timing synchronization requirements than the OTDOA technique and also has much looser group delay requirements than traditional RTT procedures.
