- -application number of the original application: 201810025081.9

The invention of the original application is named: method and device used in user equipment and base station for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus for a broadcast signal over an Unlicensed Spectrum (Unlicensed Spectrum).

Background

In a conventional 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system, data transmission can only occur on a licensed spectrum, however, with a drastic increase in traffic, especially in some urban areas, the licensed spectrum may be difficult to meet the traffic demand. Communication over unlicensed spectrum in Release 13 and Release 14 was introduced by the cellular system and used for transmission of downlink and uplink data. To ensure compatibility with other Access technologies over unlicensed spectrum, LBT (Listen Before Talk) technology is adopted by LAA (Licensed Assisted Access) to avoid interference due to multiple transmitters simultaneously occupying the same frequency resources. In Release 13 and Release 14, a base station on an unlicensed spectrum indicates whether a subsequent time domain resource of a user equipment is occupied by the base station by sending a Control signaling scrambled by a CC-RNTI (Common Control Radio Network Temporary Identifier).

Currently, a technical discussion of 5G NR (New Radio Access Technology) is in progress, wherein an important feature is unlicensed spectrum service of SA (Stand-Alone), an SA scenario broadcast signal needs to be able to support being transmitted on an unlicensed spectrum, and the transmission opportunity of the broadcast signal will be significantly reduced due to uncertainty of LBT result.

Layer 1(L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY 301. Layer 2(L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY 301.
