    摘要: A resource allocation scheduling method for a cellular communication system that can avoid interference between cells. The method includes dividing a frequency band of a system into frames each having preferential allocation blocks and general allocation blocks on a time axis, classifying terminals in each cell into groups of terminals vulnerable to interference and terminals non-vulnerable to interference, and allocating resources by terminal groups according to priority orders given to the terminal groups. The preferential allocation resources designed to have the orthogonality to the interference cells, i.e., sectors, on the time axis are allocated to the terminals vulnerable to the interference, and the remaining resources are allocated to the terminals non-vulnerable to the interference.

    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: An uplink resource allocation method is provided for transmitting a control packet on a channel different from a currently connected channel in a wireless communication system for supporting a packet based real-time service. A new format of a grant management subheader is proposed in which a piggyback request conventionally used only for the same connection can be used also for a different connection. A resource allocation request for the different connection can be made using the newly proposed grant management subheader. When the resource allocation request for a new connection is made using the grant management subheader, a resource allocation time can be reduced and loss of resources allocated for an existing connection can be minimized.

    摘要: A dynamic resource allocation method in an OFDMA system is provided. A base station determines if each of a plurality of SSs supports subchannel-based dynamic resource allocation. If an SS supports the subchannel-based dynamic resource allocation, the base station allocates resources to the SS on a subchannel basis. If the SS does not support the subchannel-based dynamic resource allocation, the base station allocates resources to the SS on a burst basis.

    摘要: A channel allocation method in a BS that communicates on at least two channels in a wireless communication system is provided. The BS receives information related to the data rates of the available channels from the MSs within its cell area, calculates the variance of the data rates for each channel, arranges the channels according to the variances, and allocates the channels in the arranged order to the MSs to satisfy the required data rates of the traffic for the MSs.
