Description

User equipment, method and device in base station used 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 method and apparatus for supporting reference signal based channel measurement on Unlicensed Spectrum.

Background technique

In the traditional 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system, data transmission can only occur on the licensed spectrum, but with the sharp increase of traffic, especially In some urban areas, licensed spectrum may be difficult to meet the demand for traffic. The communication on the unlicensed spectrum in Release 13 and Release 14 is introduced by the cellular system and used for the transmission of downlink and uplink data. To ensure compatibility with access technologies on other unlicensed spectrums, LBT (Listen Before Talk) technology is adopted by LAA (Licensed Assisted Access) to avoid multiple transmitters occupying the same time. The interference caused by the frequency resources.

At present, the technical discussion of 5G NR (New Radio Access Technology) is underway, among which Massive MIMO (Multi-Input Multi-Output) is a research hotspot of next-generation mobile communication. In massive MIMO, multiple antennas are beamforming to form a beam directed to a specific spatial direction to improve communication quality. When considering the coverage characteristics brought by beamforming, the LBT scheme in the traditional LAA needs Reconsidered.

And send the measurement results to the base station to improve transmission performance. In the LAA discussion of Release-13 and Release-14, considering the uncertainty of channel occupancy and the uncertainty of the base station transmit power, the user equipment will only assume the CRS in a downlink burst (DL Burst). The transmit power of the Cell Reference Signal (Cell Reference Signal) and the CSI-RS (Channel State Information Reference Signal) are the same, so that the user equipment will not target CRS or CSI between different downlink bursts. The measurement of the RS generates a measurement result report. At the same time, the UE (User Equipment) can perform measurement results of DRS (Discovery Reference Signal) in multiple DMTC (Discovery Signals Measurement Timing Configuration) Occasion (Time) Average to obtain mobility management for Layer 3 and path loss for uplink power control.

In 5G systems, beamforming will be used on a large scale.
