The gNB channel bandwidth supports a single NR RF carrier in the uplink or downlink. Different UE channel bandwidths may be supported within the same spectrum for transmitting to and receiving from UEs connected to the gNB. The assignment of the UE channel bandwidth is flexible and within the gNB channel bandwidth. The NR base station is able to transmit to and/or receive from one or more UE bandwidth parts (BWPs) that are smaller than or equal to the number of carrier resource blocks on the RF carrier [9]. The number of physical resource blocks configured in any channel bandwidth ensures that the required minimum guard band between neighboring ...
