Definitions

  • the present disclosure relates to the field of communication technologies, and in particular, to a data transmission method, device, base station, terminal, and computer-readable storage medium.
  • the base station configures multiple control resource sets CORESET for the terminal, and one CORESET can be associated with multiple search spaces with different periods.
  • CORESET without the transmission downlink control channel can be used for data channel transmission; at the same time, in order to simplify the complexity of the terminal when performing rate matching of the data channel, the terminal is allowed to perform rate matching around a specific CORESET.
  • the terminal cannot monitor the downlink control channel within the CORESET, which will cause scheduling restrictions.
  • CORESET may be configured as a rate matching resource (RMR) through high-level signaling.
  • RMR rate matching resource
  • This resource can be configured by the base station into different types of RMRs through high-level signaling, that is, semi-static RMRs and dynamic RMRs.
  • Semi-static RMR means that no downlink data (including the downlink data channel PDSCH and downlink control channel PDCCH) can be transmitted within this resource.
  • Dynamic RMR means that it can only be dynamically performed through L1 signaling (downlink control information DCI carried on the PDCCH). Indicates whether the resource can be used for PDSCH transmission.
  • the terminal cannot monitor the downlink control channel in a CORESET that has any resource conflict with it. This means that once the CORESET is configured as a semi-static RMR, the terminal will never be able to listen to the PDCCH in the CORESET and cannot transmit PDSCH within the CORESET; this will cause great restrictions on the scheduling of the terminal.

数据传输方法、装置、基站、终端及计算机可读存储介质
相关申请的交叉引用
本申请主张在2018年8月16日在中国提交的中国专利申请No.201810936964.5的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,特别是指一种数据传输方法、装置、基站、终端及计算机可读存储介质。
背景技术
在5G系统中,基站为终端配置多个控制资源集CORESET,且一个CORESET可以与多个具有不同周期的搜索空间相关联。为了提高频谱利用效率,没有传输下行控制信道的CORESET可以用于数据信道的传输;同时为了简化终端在做数据信道速率匹配(rate matching)时的复杂度,允许终端围绕特定的CORESET进行rate matching。但是一旦CORESET配置为速率匹配资源,终端将无法在该CORESET内监听下行控制信道,将造成调度限制。
具体地,CORESET可以通过高层信令配置为速率匹配资源(rate matching resource,RMR)。该资源可由基站通过高层信令配置成不同类型的RMR,即半静态的RMR和动态的RMR。半静态的RMR意味着在该资源内不能传输下行数据(包括下行数据信道PDSCH以及下行控制信道PDCCH),动态的RMR意味着只可以通过L1信令(PDCCH上承载的下行控制信息DCI)动态的指示该资源能否用于PDSCH的传输。
而对于半静态配置的RMR,终端不能在与其有任何资源冲突的CORESET内监听下行控制信道。这就意味着一旦CORESET被配置为半静态的RMR,则终端将始终不能在该CORESET内监听PDCCH以及不能在该CORESET内传输PDSCH;这将对终端的调度造成很大的限制。
