    Abstract: A method for controlling access of a subscriber station to a wireless communications system facilitates the maintenance of a performance target of the reverse link and desired geographic coverage of the reverse link. The method for controlling access of a subscriber station to a wireless communications system includes measuring a first performance indicator and a second performance indicator for a reverse link associated with a subscriber station seeking access to a wireless communications system. A blocking threshold value is established based upon the measured second performance indicator and may be adjusted to allow more or less blocking based on any additional metrics that characterize the performance of the current subscriber stations. The decision to grant or deny access of the subscriber station to the wireless communications system is determined based on a comparison of the measured first performance indicator to the established blocking threshold value.

    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.

    Abstract: A method is provided for maintaining synchronization between an AT and a base station during an idle period. During the idle period, a reduced number of uplink reference signals for uplink channel quality estimation are sent to the base station by the AT. The uplink reference signals are sent to assist coherent demodulation and uplink channel quality estimation for scheduling. During the uplink idle period, the numbers of uplink reference signals are designed to be reduced in selective coherent bandwidths. The selection of the coherent bandwidth alternates in time and covers the entire spectrum to allow the channel quality estimation through the entire spectrum.

    Abstract: The present invention provides a method for using uplink reference signals for access grant requests. The method includes determining at the base station that at least one mobile unit is requesting access to at least one uplink channel based on information indicative of a change in a masking sequence applied to at least one reference signal. Another embodiment of the present invention includes providing by a mobile station a first reference signal modulated by a first masking sequence to indicate a request for access to at least one uplink channel.
