8. A network entity for assigning a frequency channel, the network entity comprising:
a transceiver; and
a processor coupled to the transceiver and configured to:
receive a frequency channel assignment request from a first device;
identify a first device cluster in which the first device is includable from among at least one device cluster being operated by the network entity, wherein the first device cluster is generated based on a condition satisfied by the first device;
in case that the first device cluster is identified, update the first device cluster to include the first device; and
assign, to the first device, at least one frequency channel included in a frequency channel set assigned to the first device cluster including the first device,
wherein the first device cluster satisfies the condition and is a set of a plurality of devices, the plurality of devices to be sharing at least one frequency channel included in the frequency channel set,
wherein, in case that the first device cluster is not identified, generating a second device cluster including the first device,
wherein the first device is operated by a first network operator and a second device included in the first device cluster is operated by a second network operator, and
wherein the processor is further configured to:
from among the at least one frequency channel included in the frequency channel set:
assign a first frequency channel to the first device to be used as a primary user, and
assign a second frequency channel to the first device to be used as a secondary user when utilization of the second frequency channel is less than a threshold utilization level.
