Assigning uplink and downlink resources within bandwidth parts
Uplink and downlink resources within a wireless network are assigned such that full duplex operation is enabled within a bandwidth parts. A first bandwidth part and non-overlapping second bandwidth part are assigned for use by respective first and second groups of user equipment. Uplink resources and downlink resources are also allocated within each bandwidth part.
