  • Publication number: 20200145921
    Abstract: Techniques for improved wake-up signal (WUS) operation in a wireless communication system are described. In accordance with one embodiment, a wireless communications device may receive, from a gNB, information indicating parameters associated with a wake-up signal time window and may power down its first receiver and second receiver based on a discontinuous reception (DRX) cycle. The wireless communications device may wake up the second receiver to receive, from the gNB, a wake-up signal during a configured WUS time window and determine whether a wake-up or a non-wake-up condition is indicated. If a wake-up condition is indicated, then the wireless communications device may wake up the first receiver before an on duration of the DRX cycle to synchronize timing with the gNB, detect a new radio physical downlink control channel (NR-PDCCH) during the on duration of the DRX cycle, and reset a size of the wake-up signal time window.

  • Publication number: 20200136758
    Abstract: A method and apparatus are disclosed for identifying different types of reception failures of a packet. A station (STA) may receive a packet from a transmitting STA and determine whether it is properly received by performing at least one check of a plurality of checks. The STA may determine that reception of the packet was not properly received due to a reception failure based on the at least one check and may generate a negative acknowledgement signal (NACK) signal including an indication of the reception failure cause to enable the transmitting STA to remediate the reception failure cause. The least one check includes determining whether a frame check sequence (FCS) passes, whether a CSMA wireless medium remains busy immediately after an expected packet transmission time, whether there is a power spike during reception of the signal, or whether there are Short training field (STF) and Long Training Field (MT) correlations.
