Multiple concurrent bandwidth parts for a base station of a cellular network

A cellular communication system, the cellular communication system comprising:

• a base station functioning as part of a cellular network that communicates with a plurality of user equipment, wherein the base station is configured to:
• define a first bandwidth part and a second bandwidth part to be implemented concurrently by the base station of the cellular network, wherein:
• the first bandwidth part and the second bandwidth part do not overlap and are separated by a guard band;
• the first bandwidth part has a wider bandwidth than the second bandwidth part;
• and
• the first bandwidth part uses a first subcarrier spacing (SCS) that is greater than a second SCS of the second bandwidth part;
• assign a first set of user equipment to use the first bandwidth part and the first SCS for communication with the base station based on a signal strength of each piece of user equipment of the first set of user equipment being greater than a signal strength threshold;
• assign a second set of user equipment, distinct from the first set of user equipment, to use the second bandwidth part and the second SCS for communication with the base station based on a signal strength of each piece of user equipment of the second set of user equipment being less than the signal strength threshold;
• and
• perform communication with the first set of user equipment using the first bandwidth part and the first SCS and the second set of user equipment using the second bandwidth part and the second SCS.
