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.
