    Abstract: PROBLEM TO BE SOLVED: To control access to an uplink link so as to prevent increase of failed access of subscriber's terminals to a radio communication system. SOLUTION: To easily maintain the target performance an uplink and a desired service area map of the uplink, and control an access by a subscriber terminal 24 to the radio communication system 11, a radio communication system 11 measures a first and a second performance indicator for the uplink to a base station 10 which the subscriber terminal 24 is searching for so as to access. A blocking threshold is established based on the second performance indicator. The radio communication system 11 determines whether or not to allow access by subscriber terminal 24 based on a comparison between the measured first performance indicator and the established blocking threshold.

    Abstract: PROBLEM TO BE SOLVED: To control the level of power transmitted by a radio terminal corresponding to the violently fluctuating condition of an environmental factor between confusion and quietness by transmitting a second signal at a second power level based on a first power level and a step size. SOLUTION: In spite of whether a power control parameter updating message is transmitted or not, power control bi is transmitted to a radio terminal 502. The radio terminal 502 receives the transmitted power control signal bi . Then, the radio terminal 502 determines the control step size of a recent power level Pi-1 for generating a power level Pi for a signal Si to be next transmitted by analyzing (n) pieces of power control signals bi-n+1 to b1 received recently. The radio terminal 502 determines the power level Pi-1 to transmit the signal Si . The power level Pi is based on the preceding power level Pi-1 , power control signal bi and step size.

    Abstract: A method is provided for operating a multi-bandwidth OFDMA system that can achieve an enhanced bandwidth efficiency due to windowing without significantly impacting the underlying physical design of the receive filters. The method comprises establishing a bandwidth over which the radio resources transmit signals, the bandwidth being comprised of an edge-band and a center-band. Narrow band radio resources are assigned to a portion of the bandwidth that is at least partially within the edge-band.

    Abstract: A technique for controlling the power with which a wireless terminal transmits is disclosed. One embodiment of the present invention comprises: transmitting a first signal at a first power level; receiving a series of n power control signals, bi-n+1 through bi; setting a step size based on a measure of dispersion of the n power control signals; and transmitting a second signal at a second power level that is based on the first power level and the step size.
