  • Data transmission method and user equipment
    Patent number: 10165556
    Abstract: Embodiments disclose a data transmission method and user equipment. The method includes sending, by user equipment (UE), uplink data to a network side device; and processing, by the UE according to feedback information for the uplink data and received from the network side device, a buffer status report (BSR) corresponding to the uplink data or a scheduling request (SR) corresponding to the uplink data.
    Type: Grant
    Filed: March 11, 2016
    Date of Patent: December 25, 2018
    Assignee: Huawei Technologies Co., Ltd.
    Inventors: Xunxun Chu, Zhaodi Chen
  • Physical uplink control channel resource allocation method and apparatus
    Patent number: 10111214
    Abstract: The present disclosure discloses a physical uplink control channel resource allocation method and apparatus. The method includes: configuring a PUCCH resource for a PCC, where the PUCCH resource includes at least two PUCCH code channel groups, and each PUCCH code channel group includes at least two PUCCH code channel pairs; determining a PUCCH resource allocated to an SCC, where a same code channel group in the PUCCH resource is allocated to at least two SCCs; and determining code channel pairs used by the SCCs to which the same code channel group in the PUCCH resource is allocated, so that any two SCCs among the SCCs to which the same code channel group in the PUCCH resource is allocated use non-overlapping code channel pairs, so that multiple SCCs share a same PUCCH resource, thereby reducing PUCCH resource consumption, and increasing PUCCH resource utilization, and also increasing an uplink system throughput.
