Title:
METHOD AND APPARATUS USED IN NODE FOR WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2022/057817
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus used in a node for wireless communication. The method comprises: a node first sending a first feature sequence and a target signal; then, monitoring first signaling in a first time window; and when the first signaling is detected, demodulating a first signal, wherein a channel occupied by the first feature sequence comprises a random-access-related channel; the target signal comprises a first identifier, the first signal comprises the first identifier and a second identifier, and a CRC check included in the first signaling is scrambled by means of a third identifier; the first signaling indicates the first signal; the target signal is used for triggering the first signal; the first identifier and the second identifier are respectively a C-RNTI, and the third identifier is different from the first identifier; and the first time window is related to a time-domain resource occupied by the target signal. In the present application, a mobility management method and apparatus for a physical layer under beamforming are optimized, so as to improve the positioning performance.
