Patent ID: 8126472

Claim:
A hybrid wireless communication system supporting a time division duplexing (TDD) mode and a frequency division duplexing (FDD) mode, the system comprising: a base station having a cellular communication range based on a cellular mode; the base station determining a location of a switching time of each frame based on the amount of traffic necessary for each of a real-time service and non-real-time service; and a plurality of mobile stations within the cellular communication range, wherein the base station is configured to divide each available frequency resource into frames for communication, each frame switches between a real-time service mode and a non-real-time service mode at the switching time within the frame, communication is performed with the plurality of mobile stations via an uplink and a downlink in the real-time service mode of each frame according to the cellular mode based on the FDD mode, and communication is performed with the plurality of mobile stations via the uplink and the downlink in the non-real-time service mode of each frame according to an ad hoc mode based on the TDD mode, and wherein the base station is configured to vary the location of the switching time of each frame based on the amount of traffic necessary for each of a real-time service and a non-real-time service, the base station communicates directly with a target mobile station in the FDD mode and the base station communicates with the target mobile station via at least one relay node in the TDD mode, time slots of the uplink and the downlink have an asymmetric ratio or a symmetric ratio depending on the amount of traffic necessary for each of the uplink and the downlink and the base station broadcasts the switching time to each of the plurality of mobile stations.
