Adaptive uplink/downlink timeslot assignment in a hybrid wireless time division multiple access/code division multiple access communication system
Abstract
A hybrid time division duplex/code division multiple access communication system comprises a radio network controller coupled to a plurality of Node-Bs. The radio network controller comprises a resource allocation device for providing each Node-B with a list of timeslots that the Node-B can use to assign uplink timeslots and downlink timeslots. The list of timeslots does not include all potential timeslots as being assignable for uplink communications and does not include all potential timeslots as being assignable for downlink communications. Each of the plurality of Node-Bs comprises an assignment device for dynamically assigning uplink and downlink communications to users of the Node-B in response to the assignable uplink and downlink timeslots of the list.
