  • Publication number: 20230209366
    Abstract: A new design for physical downlink control channel (PDCCH) is proposed for the next generation 5G new radio systems. A UE receives the configuration of a default control resource set (CORESET) in MIB/SIB from its serving base station. The default CORESET contains both common search space and UE-specific search space for candidate PDCCH transmission. A PDCCH in a default CORESET is mapped to physical resource in a distributed or localized manner. Specifically, various REG-to-CCE mapping rules are proposed to improve frequency diversity gain, or frequency selectivity gain, or to reduce latency of PDCCH processing. Further, to facilitate analog beamforming in mmWave systems, the default CORESET is transmitted in a synchronization signal (SS) block associated with a corresponding analog beam direction.

  • Patent number: 11653301
    Abstract: Various solutions for wake-up signal and preamble design for mobile communications are described. An apparatus, while in a first mode of operation, receives a wake-up signal (WUS) from a network. In response to receiving the WUS, the apparatus switches to a second mode of operation from the first mode of operation. The apparatus then detects a preamble in downlink (DL) transmissions from the network. In response to detecting the preamble, the apparatus monitors a physical downlink control channel (PDCCH) to check for an uplink (UL) transmission grant for the apparatus from the network.
