Document Type and Number:
WIPO Patent Application WO/2019/076171
Kind Code:
A1
Abstract:
Disclosed are a method, terminal, and network device for information transmission in an unlicensed band. The method comprises: listening to transmission channels of a first bandwidth part of an unlicensed frequency band to produce a channel listening result, where the first bandwidth part is at least one bandwidth part corresponding to received uplink grant scheduling information and/or uplink transmission resource preconfiguration information; if the channel listening result indicates that a bandwidth part having transmission channels is present in the first bandwidth part, then at least one bandwidth part is selected from the bandwidth part having idling transmission channels for activation to produce a first activated bandwidth part; and information is transmitted to a network device on the first activated bandwidth part.
