    摘要： A transmission method based on random beamforming. A base station receives, from mobile stations, feedback information including channel-by-channel transmission rates for a weight vector arbitrarily set by the base station. The base station compares transmission rates of identical channels received from the mobile stations. The base station allocates an associated channel to a mobile station with a large transmission rate and transmits a signal through the allocated channel. The transmission method based on random beamforming can improve fairness and efficiency of a resource allocation by simultaneously allocating different channels to multiple terminals and can increase a total system capacity through the improved fairness and efficiency.

    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.
