    摘要： Disclosed is a method for transmitting an uplink data during handoff A method for transmitting uplink data in a soft handoff system, in which a mobile station is simultaneously connected with at least two base transceiver systems under a control of a base station controller, includes selecting one of the base transceiver systems as a main base transceiver system, transmitting uplink signals to the main base transceiver system and sub-base transceiver systems, and transmitting by the sub-base transceiver systems received uplink signals to the main base transceiver system. Through the method, a main BTS for diversity combining and decoding soft bit strings is established among BTSs connected to a mobile station, so that it is possible to distribute a data processing amount centralized on a BSC to a BTS.

    摘要： A method for determining a handoff of a mobile station (MS) in a mobile communication system. In the method, a serving base station (BS) measures a level of a first uplink signal by monitoring an uplink to the MS. The serving BS receives a level of a second uplink signal, measured and reported by at least one neighbor BS. The serving BS determines a handoff for the MS considering the level of the first uplink signal and the level of the second uplink signal.

    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.
