摘要： The disclosure provides methods and apparatuses for adjusting a CWS value between a predefined minimal CWS value and a predefined maximal CWS value at a UE side for UL transmissions. The method includes performing a plurality of CCAs within one UL LBT round to determine measurements of channel conditions in respective CCAs; and adjusting the CWS value according to the measurements of channel conditions in the plurality of CCAs for use in the next UL LBT round. Another method includes acquiring information about HARQ feedback values for a reference subframe set; and adjusting the CWS value according to the information for use in a next LBT round.

摘要： Embodiments of the present disclosure relate to a method of autonomous uplink signal transmission and a corresponding terminal device and network device. For example, at a side of a terminal device in a communication network, an indication of a resource configuration is received from a network device for transmitting an autonomous uplink signal to the network device, and a sub-frame is determined based on the received indication of the resource configuration for transmitting the autonomous uplink signal. Then, the terminal device transmits the autonomous uplink signal to the network device in the determined sub-frame. The corresponding method implemented at the network device as well as the terminal device and network device capable of implementing the above methods are also disclosed.

摘要： The present disclosure relates to a method and device for signal processing in a communication system. The present disclosure uses orthogonal and quasi-orthogonal spreading sequences and spatial channels to discriminate data of a terminal device. Since the spreading sequences utilized by data of the same terminal device are orthogonal, interference from the user itself is eliminated. As spreading sequences utilized by different terminal devices are quasi-orthogonal, interference between users is inhibited through spatial channels. Compared with other non-orthogonal multi-user access scheme, the present disclosure increase the supported overloading factor by combining the orthogonal spreading sequences and spatial channels.

摘要： 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.

摘要： 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.
