Abstract

The invention discloses a method and a device in user equipment and a base station used for wireless communication. The user equipment receives first information and sends a first wireless signal in afirst time window on a first sub-band; the first information is used for determining the first time window; the time offset of the initial sending moment of the first wireless signal relative to thereference moment belongs to a target offset set, and the target offset set comprises W offset values; the time offsets of the W starting moments relative to the reference moment are respectively equalto the W offset values; any starting moment in the W starting moments belongs to one time unit in N time units, and any time unit in the N time units comprises at least one starting moment in the W starting moments; and at least one of the N and the target offset set is related to a subcarrier interval of a subcarrier occupied by the first wireless signal.

Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, in particular to a communication method and device supporting data transmission on an unlicensed spectrum (Unlicensed Spectrum). Background technique [0002] In the traditional 3GPP (3rd Generation Partner Project, third-generation partnership project) LTE (Long-term Evolution, long-term evolution) system, data transmission can only occur on the licensed spectrum. However, with the rapid increase of traffic, Especially in some urban areas, the licensed spectrum may be difficult to meet the demand of business volume. The communication on the unlicensed spectrum in Release 13 and Release 14 is introduced by the cellular system and used for downlink and uplink data transmission. In order to ensure compatibility with other access technologies on unlicensed spectrum, LBT (Listen Before Talk) technology is adopted by LAA (Licensed Assisted Access) of LTE...
