Title:

CSI FEEDBACK IN LTE(R)/LTE-ADVANCED SYSTEMS WITH UNLICENSED SPECTRUM

Document Type and Number:

Japanese Patent JP2020036329

Kind Code:

A

Abstract:

To provide methods of channel state information (CSI) feedback in long term evolution (LTE) and LTE-Advanced (LTE-A) networks including unlicensed spectrum.SOLUTION: A base station obtains 500 clear channel assessment (CCA) result information about multiple neighboring base stations. The base station generates 501 control signaling on the basis at least partly of the obtained CCA result information for multiple user equipment pieces (UEs) served by the base station. The base station transmits 502 the generated control signaling to the multiple UEs.SELECTED DRAWING: Figure 5A
