Abstract

The invention provides methods and devices for sending and receiving random access signals. The receiving method comprises the steps that a first node sends resource configuration information to a second node; and the first node receives a random access signal sent by the second node according to the resource configuration information, wherein the resource configuration information is used for indicating the second node to send the random access signal at an effective random access opportunity. Through the method and the device, the problem of effectiveness judgment of the random access opportunity in related technologies is solved, so that the effects of more reasonably judging the effectiveness of the random access opportunity, reducing useless signal transmission and avoiding unnecessary interference and power consumption are achieved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for sending and receiving random access signals. Background technique [0002] The new generation mobile communication system (New Radio, NR for short) allows more flexible network networking methods and the existence of new types of network nodes than 2G, 3G, and 4G systems. At present, a new type of node integrating a backhaul link (Backhaul Link) and a normal NR access link (Access Link) integrated access and backhaul node (Integrated Access and Backhaul Node, referred to as IAB) can provide better than a single cellular coverage. The most flexible coverage and networking methods will be an important part of the future mobile communication network. [0003] For a new generation of mobile communication systems using IAB nodes, IAB nodes can be regarded as ordinary terminal UEs or as base stations accessed by other UEs. Since IAB nodes cannot transmit a...
