Description

信息传输方法、基站和终端设备Information transmission method, base station and terminal device

技术领域Technical field

本发明实施例涉及通信技术，尤其涉及一种信息传输方法、基站和终端设备。The embodiments of the present invention relate to communication technologies, and in particular, to an information transmission method, a base station, and a terminal device.

背景技术Background technique

第5代(5^th Generation，简称5G)通信***致力于支持更高***性能，业务类型也呈现多样化。其中，对于时延敏感的业务如车联网、机器人等场景，都对端到端传输的时延及可靠性有着非常严苛的要求。该时延敏感业务可称为超可靠低延迟通信(Ultra-Reliable and Low Latency Communications，简称URLLC)业务。5th generation (5 ^th Generation, referred 5G) communication system is committed to supporting higher system performance, type of business is also diversified. Among them, delay-sensitive services such as car networking, robots and other scenarios have very strict requirements on the delay and reliability of end-to-end transmission. The delay sensitive service may be referred to as an Ultra-Reliable and Low Latency Communications (URLLC) service.

目前的长期演进(Long Term Evolution，简称LTE)的通信***中，为避免资源浪费，终端设备在没有上线数据传输的情况下，基站通常不会为其分配上行资源的。如源终端设备每次向目标终端设备传输数据之前，均需先向基站发送调度请求(Scheduling Request，简称SR)，使得基站为该终端设备分配缓存状态请求(Buffer Status Report，简称BSR)的上行资源。该源终端设备根据该BSR的上行资源向该基站发送BSR，使得该基站根据该BSR确定该源终端设备待传输数据量，继而根据待传输数据量为该源终端设备分配上行数据的上行资源。源终端设备在确定上行数据的上行资源后，可根据该上行数据的上行资源通过数据信道传输上行数据，继而由基站将该上行数据传输至目标终端设备，实现源终端设备与目标终端设备间点到点(Point To Point)的数据传输。In the current Long Term Evolution (LTE) communication system, in order to avoid waste of resources, the terminal device usually does not allocate uplink resources to the terminal device without uplink data transmission. For example, the source terminal device needs to send a scheduling request (Scheduling Request, SR for short) to the base station before the source terminal device transmits the data to the target terminal device, so that the base station allocates a buffer status request (BSR) uplink to the terminal device. Resources. The source terminal device sends a BSR to the base station according to the uplink resource of the BSR, so that the base station determines, according to the BSR, the amount of data to be transmitted by the source terminal device, and then allocates uplink resources for the source terminal device according to the amount of data to be transmitted. After determining the uplink resource of the uplink data, the source terminal device may transmit the uplink data through the data channel according to the uplink resource of the uplink data, and then the base station transmits the uplink data to the target terminal device to implement the point between the source terminal device and the target terminal device. Data transfer to Point To Point.

然而，源终端设备每次向目标终端设备传输数据之前均需向基站请求上行资源，并且，用于请求上行资源的SR和BSR均是通过控制信道发送的，这使得由源终端设备与目标终端设备间点到点(Point To Point)的数据传输的时延较大。However, the source terminal device needs to request the uplink resource from the base station before transmitting the data to the target terminal device, and the SR and the BSR for requesting the uplink resource are all sent through the control channel, which is caused by the source terminal device and the target terminal. The data transmission time between points to Point (Point To Point) is large.
