Description

Method and device used in user equipment and base station of unlicensed spectrum

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus over an unlicensed spectrum.

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of multiple application scenarios, a New air interface technology (NR, New Radio) (or 5G) is determined to be studied in 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 guilds, and standardization Work on NR starts after passing through WI (Work Item) of the New air interface technology (NR, New Radio) in 3GPP RAN #75 guilds.

In order to be able to adapt to diverse application scenarios and to meet different requirements, a research project of access to Unlicensed Spectrum (Unlicensed Spectrum) under NR is also passed on 3GPP RAN #75 universal meetings, which is expected to be completed in version R15, and then WI is started to standardize the related art in version R16.

Disclosure of Invention

In the LAA (licensed Assisted Access) project of LTE (Long Term Evolution), in order to determine that an unlicensed spectrum is available while ensuring synchronization on the unlicensed spectrum, an LTE base station (eNB) transmits a DRS (Discovery Reference Signal) on an unlicensed frequency domain. DRS can only be transmitted on configured resources available for DRS transmission while meeting unlicensed spectrum access regulations (e.g., LBT, Listen Before Talk). A signal similar to DRS is also required in unlicensed spectrum access by NR. In the unlicensed spectrum of NR, including the spectrum of the high band (generally higher than 6GHz), it becomes necessary to implement coverage using a large-scale antenna because the transmission loss of the high band spectrum is very large. But in order to achieve the limitation of simplicity and cost, Beam Sweeping (Beam Sweeping) based on Analog Beamforming (Analog Beamforming) is widely adopted. Special design is required when using beam sweeping for DRS-like signal transmission.
