  • Publication number: 20190124692
    Abstract: Techniques for procedures using request to send/clear to send (RTS/CTS) procedures and multiple timers are described. A RTS/CTS procedure using multiple timers may use a first timer and a second timer. The first timer may be associated with a duration to transmit and receive a request to send (RTS) message and a clear to send (CTS) message. The second timer may be associated with a duration to transmit a data message. A network device may transmit a RTS message to request communication resources to transmit data. If the CTS message is not received prior to the expiration of the first timer, neighboring network devices may determine that the communication resources were not allocated and may attempt to request the newly available resources. If a CTS message is received, the network device may communicate the second timer data to the neighboring network devices in a variety of ways.

  • Publication number: 20190082332
    Abstract: A beam selection method and apparatus suitable for millimeter wave (mmW) communication systems is disclosed. In one aspect, a user equipment (UE) may perform a beam sweep procedure to identify suitable downlink beams candidates from one or more gNBs.
