Title:
FREQUENCY HOPPING METHOD AND DEVICE IN UNLICENSED BAND
Document Type and Number:
WIPO Patent Application WO/2020/036464
Kind Code:
A1
Abstract:
The present embodiments provide a method and a device therefor, the method comprising: on the basis of uplink frequency-domain resource allocation information for uplink data transmission in a bandwidth part configured in a unlicensed band or a cell system bandwidth configured in a unlicensed band, performing an LBT operation for each subband to which frequency resources allocated for uplink data transmission belong; determining a subband for uplink data transmission on the basis of the result of the LBT operation; and when uplink data is transmitted in the determined subband, transmitting the uplink data by performing subband-based frequency hopping or bandwidth part-based frequency hopping.
