1. A user equipment (UE) comprising:
a processor; and
memory storing computer-executable instructions that, when executed by the processor, causes the UE to at least:
determine a wide channel;
determine at least one sub-channel within the wide channel, a channel bandwidth (BW) of the at least one sub-channel being a first BW;
receive a configuration of at least one downlink (DL) or uplink (UL) carrier, a channel BW of the at least one carrier being a second BW;
determine a first and last usable physical resource block (PRBs) of the at least one sub-channel based on the first BW and the second BW by
setting first and last useable PRBs of the at least one sub-channel based on a first pair of guard bands (GBs), if a size of the second BW is equal to a size of the first BW, and
setting the first and last useable PRBs of the at least one sub-channel based on a second pair of GBs, if the size of a second BW is less than the size of the first BW, a size of a total bandwidth of the second pair of GBs being greater than a size of a total bandwidth of the first pair of GBs; and
perform at least one of transmitting data to, or receiving data from, a network element via the at least one DL carrier or UL carrier.
