Abstract
A method by which a terminal operating in an unlicensed band transmits a signal includes the steps of: receiving, from a base station, configuration information about a carrier; receiving configuration information for configuring N (where N is an integer) guard band(s) for some frequency domains of the carrier; and transmitting a signal to the base station by using a first frequency domain of a bandwidth part belonging to the carrier, wherein the first frequency domain can be a domain excluding the N guard band(s) from the frequency domain of the bandwidth part.
Claims20
A method for transmitting a signal, performed by a terminal operating in an unlicensed band, the method comprising:
- receiving, from a base station, first configuration information of a carrier including a first set of resource blocks (RBs), the carrier including guard band(s) and subbands;
- receiving, from the base station, second configuration information for configuring location(s) of the guard band(s), the guard band(s) being a first subset of RBs belonging to the first set, the subbands being a second subset of RBs belonging to the first set,
- receiving, from the base station, third configuration information for configuring a bandwidth part including one or more subbands among the subbands, the bandwidth part belonging to the carrier;
- and
- transmitting a signal to the base station using a third subset of RB(s) of the bandwidth part.
