  • Patent number: 10931412
    Abstract: Embodiments of the present disclosure provide a method and apparatus of obtaining feedback of HARQ acknowledgment information. The method comprises allocating to UE an uplink control channel resource for report of HARQ acknowledgment information related to downlink data transmission on an unlicensed carrier. The method also comprises obtaining feedback of the HARQ acknowledgment information from the UE within a predefined deferral window. The predefined deferral window specifies a minimum delay and a maximum delay for report of the HARQ acknowledgment information. The embodiments of the present disclosure may increase the reliability and reduce the latency of HARQ acknowledgment information feedback. In addition, the embodiments of the present disclosure may not only be for LAA scenarios, but also may be extended to standalone LAA access scenarios on unlicensed carriers.

  • Publication number: 20200382248
    Abstract: Embodiments of the present disclosure relate to a method and device for backhaul transmission. In example embodiments, the first network device transmits uplink (UL) data to a second network device in a first UL backhaul link, the first UL backhaul link being scheduled by the first network device. The second network device is located in upstream of the first network device. The first network device receives downlink (DL) data from the second network device in a first DL backhaul link. The first DL backhaul link is scheduled by the second network device. In this way, the transmission latency may be reduced, and the transmission efficiency may be improved.

  • Publication number: 20200383031
    Abstract: Embodiments of the present disclosure provide a method, device and computer readable storage medium implemented at a relay device. According to embodiments of the present disclosure, the relay device determines whether a terminal device served by a network slice has to be handed over. In a case of determining that the terminal device has to be handed over, the relay device sends a request for local information to at least one candidate relay device, and the local information includes at least one of information associated with a backhaul link from a candidate relay device to a network device and slice configuration information of the candidate relay device. Based on the received local information, the relay device determines a candidate relay device for handover of the terminal device.

  • Publication number: 20190159243
    Abstract: The disclosure provides a method for assisting a UE to implement a UL channel access in a base station of an eLAA-based communication system. The method comprises determining a listen-before-talk (LBT) priority for the UE; and transmitting a first signaling indicating the determined LBT priority to the UE. An enhanced UL channel access mechanism is proposed by the disclosure. In this mechanism, the eNB can provide some assistance to facilitate UL access. Chances of multiple user multiplexing and spectrum efficiency in LAA UL can be improved by this solution.
