Title:
METHOD AND DEVICE USED IN USER EQUIPMENT AND IN BASE STATION FOR WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2019/119174
Kind Code:
A1
Abstract:
The present application discloses a method and a device used in user equipment and in a base station for wireless communication. The method comprises: user equipment receiving first information, the first information being used for determining N multi-carrier symbols on a first sub-band, N being a positive integer greater than 1; performing first access detection to determine M multi-carrier symbols among the N multi-carrier symbols; for the N multi-carrier symbols on the first sub-band, sending M reference signals merely in the M multi-carrier symbols, respectively, the M reference signals being used to determine the M multi-carrier symbols among the N multi-carrier symbols, M being a positive integer not greater than N. The method above solves the problem of transmission of a plurality of uplink wireless signals corresponding to beam-based unlicensed spectrum access detection.
