Title:
METHOD AND DEVICE IN NODE FOR USE IN WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2020/207243
Kind Code:
A1
Abstract:
Disclosed are a method and device in a node for use in wireless communication. A first node first performs channel monitoring so as to determine that K1 sub frequency bands in K sub frequency bands are idle, and then transmits a first control information block and a second control information block on a first channel; the first channel occupies the K1 sub frequency bands in the K sub frequency bands; K1 copied first control information blocks are respectively transmitted on the K1 sub frequency bands, and the second control information block is merely transmitted once on the first channel; the first control information block is used for indicating the sub frequency band occupied by the second control information block; the mapping of the second control information block in the sub frequency band is uncorrelated with K1. By classifying uplink control information, transmitting same in different modes, and performing mutual indication on different groups of uplink control information, the present application improves uplink transmission efficiency and performance on an unlicensed spectrum.
