Method and apparatus for uplink communication in unlicensed band
Abstract:
An operation method of a terminal may comprise receiving information on one CG configuration for uplink transmission from a base station; obtaining common time domain resource allocation information for combinations of RB sets based on the information on the one CG configuration; obtaining frequency domain resource allocation information for each of the combinations of the RB sets based on the information on the one CG configuration; determining a number of PRBs to which an uplink channel is mapped based on the frequency domain resource allocation information corresponding to one combination of the combinations; determining a TBS based on the common time domain resource allocation information and the number of PRBs; and transmitting a TB having the TBS to the base station within the one combination through the uplink channel according to the common time domain resource allocation information and the frequency domain resource allocation information.
