    摘要: In an adaptive feedback method for a cellular communication system having plural terminals feeding back channel information to an access point, the system selects one of an opportunistic mode and a polling mode as a feedback mode between an access point and the terminals on the basis of system and traffic parameters, sets up the access point and the terminals for the selected feedback mode, and feeds back the channel information from the terminals to the access point in the selected feedback mode. The adaptive feedback method changes the feedback mechanism adaptively to the system and traffic environment, making it possible to increase the system throughput as well as to decrease the MAC overhead regardless of the variation of the number of MSs.

    摘要: A method for transmitting to one cell a frame including broadcast channels in a cellular wireless communication system in which a base station supports a plurality of physical channels corresponding to the broadcast channels. The base station generates the frame and transmits the generated frame to a mobile station. The frame includes separate broadcast channels for the respective physical channels. A position, in the frame, of a first broadcast channel for a physical channel capable of supporting a mobile station having the worst channel state is fixed in all of transmission frames. The first broadcast channel includes positional information of the remaining broadcast channels except for the first broadcast channel. The mobile station detects only an address of a broadcast channel for a physical channel allocated thereto from the first broadcast channel among broadcast channels belonging to the frame.

    摘要: A mobile communication system includes a medium access control (MAC) layer, and the MAC layer supports an idle state (719) in which no downlink and uplink dedicated control channel and dedicated traffic channel exists and also supports an active state (711) in which the downlink and uplink dedicated control channel and dedicated traffic channel exist. The MAC layer controls transitioning to a contention state (717) and then transitioning from the contention state (717) to the active state (711) through contention-based access, if there is transmission data in the idle state; transitioning to a fast access state (713) or a slow access state (715) according to priority of the data if there is no transmission data in the active state (711) for a preset time; transitioning to the active state (711) through contention-free-based access if there is transmission data in the fast access state (713); and transitioning to the active state (711) through contention-free-based access if there is transmission data in the slow access state (715).

    摘要: A method of constructing a micro- or pico-cells and a virtual macro-cell hierarchical cellular system structure comprising contiguous cells each containing a base station and sectors, wherein a virtual cell comprising three surrounding FDD macro-cell base stations over underlay the TDD micro- or pico-cells. In the proposed TDD/virtual FDD hierarchical cellular structure, a method of locating underlay cells' base station and macro-cells' base station to keep a least interference distance and a method of aligning the TDD micro-or pico-cells' sectors antenna beam direction with the FDD macro-cells' sectors beam direction are proposed, such that this system can suppress the additional inter-system interference and adjacent channel interference. The algorithm of utilising and borrowing the underused FDD macro-cells' resource and the mechanism of deciding the feasible resource borrowing region and smart antenna applicable region is proposed in such a way that the radio network controller and TDD micro- or pico-cell base stations can build up and decide the preference list of which sector, users, and resource to be served, which eventually resulting in the flexible and adaptive radio resource management of the RNC and achieving the optimal utilisation of the overall system resource.
