摘要： A handoff method in a mobile communication system using frequency hopping-orthogonal frequency division multiplexing (FH-OFDM). A mobile host predicts a handoff according to strength of transmission power of a currently serving base station, reserves a physical channel required for the handoff associated with at least one candidate base station, selects a handoff target base station from the at least one candidate base station, releases a channel with the serving base station, and performs data communication with the target base station through the reserved physical channel.

摘要： A radio resource allocating method in an adaptive antenna system is provided. The radio resource allocating method includes selecting one user when there are one or more users allocable to a current spatial frame; calculating a sum of Modulation order Product code Rate (MPR) values with respect to users allocated a same radio resource including the selected user when a total transmit power of a Base Station (BS) is divided by a current spatial frame index; and allocating the selected user to the current spatial frame by taking into account the calculated sum and a sum of MPR values with respect to users allocated to a previous spatial frame. Accordingly, a system throughput or a scheduler performance can be maximized.

摘要： Provided is an apparatus and method for allocating a radio frequency band resource in a Space Division Multiple Access (SDMA) system. The scheduler allocates a data burst, extracts a surplus power resource from each channel band, redistributes the extracted surplus power resource to the data burst, outputs redistributed transmission power information to a power controller, and outputs allocated burst information and the data burst to a modulation block. The power controller receives the transmission power information from the scheduler, and outputs a weight associated with a transmission power. The multiplier receives a frequency domain signal, multiplies the received frequency domain signal by the weight, and outputs the multiplied result to an IFFT operator.

摘要： Provided is an apparatus and method for power allocation in a Space Division Multiple Access (SDMA) system. The apparatus includes an encoder, an antenna weighting calculator, and an antenna. The antenna weighting calculator divides a transmission power of a Base Station (BS) by number of Mobile Stations (MSs), fixedly distributes the divided transmission powers to the MSs, calculates a surplus power of each MS, sums up the calculated surplus power to thereby calculate a total surplus power, calculates a power per MS needed for an MPR one level higher, determines whether there is an MS whose power needed for a next level MPR is smaller than the total surplus power, and additionally allocates the total surplus power when there is the MS.
