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 that supports an idle state in which no downlink and uplink dedicated control channel and dedicated traffic channel exists and also supports an active state in which the downlink and uplink dedicated control channel and dedicated traffic channel exist. The MAC layer controls transitioning to a contention state and then transitioning from the contention state to the active state through contention-based access, if there is transmission data in the idle state; transitioning to a fast access state or a slow access state according to priority of the data if there is no transmission data in the active state for a preset time; transitioning to the active state through contention-free-based access if there is transmission data in the fast access state; and transitioning to the active state through contention-free-based access if there is transmission data in the slow access state.

摘要： Provided is an apparatus and method for enhancing the link performance of a multicast service for UEs in a wireless system. In the method, multicast data received in an Nth frame is recovered using systematic packets. When the recovery fails, parity packets are received in an (N+1)th frame and are used to recover the multicast data. When the recovery fails again, an autonomous handover is performed to receive parity packets from a neighboring cell or sector, which are used to recover and the multicast data.
