Method for indicating and determining listen-before-talk parameters, base station and user equipment

摘要

Provided are a method used for indicating and determining a parameter value of Listen-Before-Talk (LBT) parameters, a base station and a user equipment, the method including: determining a parameter value of LBT parameters, the LBT parameters including an LBT type, an LBT priority, and a start position of a physical uplink shared channel PUSCH; determining an index for carrying out joint indication of the LBT parameters on the basis of a subset of a full set which is formed by combining possible parameter values of each LBT parameter; generating downlink control information including the index; and sending the downlink control information to a user equipment.
