  • Publication number: 20210226734
    Abstract: A method, an apparatus, a base station, and a user equipment (UE) for wireless communication are provided to reduce the retransmission latency for URLLC communications. Upon receiving a downlink data transmission, a UE waits until it completes decoding of the received downlink data transmission before it can send an ACK/NAK report on the decoded downlink data transmission. In case of a decoding failure, the base station cannot start retransmission until the UE finishes the decoding of the downlink data transmission and sends the ACK/NAK report and until the base station finishes decoding of an NAK in the ACK/NAK report. This considerable retransmission latency may not meet stringent latency requirements of some URLLC applications. A two-stage ACK/NAK reporting is disclosed to reduce the retransmission latency where the UE sends an early ACK/NAK report upon partially completing the decoding of the downlink data transmission.

  • Publication number: 20210218450
    Abstract: This disclosure provides systems, methods and apparatus for wireless communications in narrowband frequency bands using frequency hopping. In some implementations, a base station (BS) groups a plurality of hopping channels of a frequency hopping pattern into a number of groups based on a bandwidth part (BWP) hopping frequency of each hopping channel of the frequency hopping pattern. The BS transmits indications of the frequency hopping pattern and the grouping of hopping channels to user equipments (UEs). The BS transmits a channel state information reference signal (CSI-RS) on a first hopping channel, and receives channel state information (CSI) of the first hopping channel from one or more of the UEs. In some other implementations, a UE receives indications of the frequency hopping pattern and hopping channel groups, and determines CSI of the first hopping channel based on the received CSI-RS. The UE may transmit the CSI to the BS.
