Information sending and receiving method, terminal and control node

Abstract

The present invention provides an information sending and receiving method, a terminal and a control node, and relates to the field of communication technology. The information sending method, applied to a sending end, comprises: sending first information to a receiving end; the first information is used to assist the receiving end in determining whether to perform hybrid automatic repeat request HARQ feedback; wherein the first information comprises at least one of the following: a communication range indication, a correspondence between the length of a geographical area side and the communication range, a geographical area division rule and a coverage area identifier of the control node where the sending end is located. The above scheme can solve the problem of the HARQ feedback method in the prior art, which leads to large signaling overhead and low system resource utilization, thereby reducing communication overhead.
