Title:
METHOD AND APPARATUS FOR RECEIVING DOWNLINK AND UPLINK RADIO RESOURCES IN UNLICENSED BAND
Document Type and Number:
WIPO Patent Application WO/2021/242059
Kind Code:
A1
Abstract:
The present invention relates to a method and an apparatus for configuring downlink and uplink radio resources in an unlicensed band. The present invention provides a method comprising the steps of: receiving information indicating at least one synchronization signal/physical broadcast channel (SS/PBCH) block index from a base station in the unlicensed band; and receiving downlink control information (DCI) for allocation of resources for a physical downlink shared channel (PDSCH) in the unlicensed band from the base station. Therefore, efficient transmission of downlink and/or uplink data or control information in an unlicensed band is possible.
