    摘要: An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for Reference Signal Time Difference (RSTD)-based 5G-NR positioning. The processing circuitry is to determine a first PRS BW associated with a first PRS received from a first gNB associated with a first cell. A second PRS BW is determined, which is associated with a second PRS received from a second gNB of a second cell. An RSTD report resolution is determined based on the first PRS BW and the second PRS BW. A receive (Rx) timing difference between the first cell and the second cell is measured based on reception times of the first PRS and the second PRS. The measured Rx timing difference is mapped into an RSTD report for transmission to the first gNB, based on the RSTD report resolution.

    摘要: A delegate-based group channel access method is disclosed for machine-to-machine (M2M) communication. The delegate-based group channel access method groups M2M devices having common characteristics together, assigns a single delegate or multiple delegates from the group according to some criteria, and uses the assigned delegate to perform channel access. This method avoids unnecessary peer-to-peer communication between M2M devices reduces the probability of collision on the channel during initial channel access, and reduces the control signaling overhead. The, delegate-based group channel access method also coordinates the number of slots to backoff so that all M2M devices in the group keep pace with the delegate.
