Method and device used in user equipment and base station for wireless communication

Technical Field

The present invention relates to a transmission method and apparatus in a wireless communication system, and in particular, to a transmission method and apparatus for Unlicensed Spectrum (Unlicensed Spectrum) uplink and downlink control information.

Background

In a conventional 3GPP (3 rd 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, where an important feature is unlicensed spectrum service of SA (Stand-Alone), there is no way for the licensed spectrum to transmit downlink control signaling in an SA scenario, and meanwhile, due to uncertainty of LBT result, the transmission opportunity of the downlink control signaling will be significantly reduced.
