Abstract

The present application discloses a method and an apparatus used in a node for wireless communication. The first node receives a target signal and a first reference signal; sends a first signal group; wherein the first reference signal is used to determine a first measurement result, and the first measurement result is used to start a first timer; The first measurement result is used to trigger the first signal group; the first signal group is used to determine a second reference signal; the duration of the first timer is related to the first time window; the first A signal group occupies a second set of time-frequency resources, the second set of time-frequency resources is associated with the target signal; the target signal includes a broadcast signal; the first reference signal and the second reference signal are different ; the first signal group is used for random access. In this application, by setting the first timer associated with the first time window, the signaling process is adjusted and optimized, the time delay is reduced, and the efficiency is improved.

Description

technical field [0001] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular, to a transmission method and apparatus related to beam and link recovery to reduce time delay in wireless communication, improve transmission reliability. Background technique [0002] The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios place different performance requirements on the system. In order to meet the different performance requirements of various application scenarios, at the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network, Radio Access Network) #72 plenary meeting, it was decided that the new air interface technology (NR, New Radio) (or Fifth Generation, 5G) conducted research, passed the WI (Work Item, work item) of NR at the 3GPP RAN#75 plenary meeting, and began to standardize NR. [0003] In communication, ...
