Problems solved by technology

[0006] In the traditional 3GPP (3rd Generation Partner Project, 3rd 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, licensed spectrum may be difficult to meet traffic demands

Abstract

The invention discloses a method and a device in user equipment and a base station used for wireless communication. The user equipment receives a first broadcast signal on the first sub-band, and receives a second broadcast signal on a second sub-band; the first broadcast signal comprises a first type of synchronization signal and a first type of information block; a third broadcast signal transmitted on the second sub-band comprises a first type of synchronization signal and a first type of information block; only the first type information block included in the first broadcast signal in the first type information block included in the first broadcast signal and the first type information block included in the third broadcast signal is applied to the second broadcast signal. According to the application, the second broadcast signal is transmitted on the second sub-band through the design, and transmission of part of broadcast signals corresponding to one frequency band on the other frequency band is realized, so that the flexibility of broadcast signal transmission is improved, and the overall performance of the system is improved.

Description

[0001] This application is a divisional application of the following original application: [0002] --The filing date of the original application: 2018.01.11 [0003] --Application number of the original application: 201810025081.9 [0004] --The name of the invention of the original application: a user equipment used in wireless communication, a method and a device in a base station technical field [0005] The present application relates to a transmission method and device in a wireless communication system, in particular to a transmission method and device for a broadcast signal on an unlicensed spectrum (Unlicensed Spectrum). Background technique [0006] In the traditional 3GPP (3rd Generation Partner Project, 3rd 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, licensed spectrum may be difficult ...
