摘要： 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.

摘要： In a method for minimizing reverse link power control overshoot in a wireless communications system, the output power of a mobile station is detected to determine whether it falls outside a dynamic range of the mobile station. If outside the dynamic range, a new output power falling within the dynamic range is calculated and set, and the mobile station is instructed to transmit at the new output power.

摘要： A method is disclosed for determining when a request for a higher transmission rate should be granted to a mobile station that currently has access to a communication system to facilitate the maintenance of a performance target (quality of service level) of the reverse link. The method for determining when a mobile station can have access to a higher transmission rate includes obtaining first and second estimated performance indicators for a reverse link of the base station that a mobile station is currently accessing. A blocking threshold value is established. Access at the requested higher transmission rate is based on a comparison of the first and second indicators relative to the established blocking threshold value. If access is denied at the requested higher rate, access will be granted at the next lower rate which will not degrade the performance of the wireless communication system.

摘要： A wireless communication system is provided that includes a network and a plurality of access terminals. The plurality of access terminals includes a first group of access terminals configured to receive control information at a first data rate and send a response to the received control information, as well as a second group of access terminals configured to receive the control information at a second data rate and send a response to the received control information. The second data rate is higher than the first data rate. The network is configured to send the control information via a control channel at the first data rate and the second data rate, receive responses from the access terminals, and establish a traffic channel with at least one of the access terminals based on the control information and associated response from at least one of the access terminals.

摘要： The present invention provides a method for implementation in a base station that supports at least one downlink traffic channel and at least one overhead channel. The method includes determining power allocation(s) for overhead channel(s) based upon a measurement of downlink traffic channel power and a maximum transmission power of the base station. The method also includes transmitting signals over the overhead channel(s) using the power allocation concurrently with transmission of signals over the downlink traffic channel.

摘要： Link performance is measured in a code division multiple access (CDMA) personal communication service (PCS) or cellular system, or other type of wireless system, using a test set-up which permits the simulation of various changes in system configuration. An illustrative embodiment includes a first attenuator arranged in a common portion of a receive path and a transmit path of a mobile station of the system, and a second attenuator arranged in either a receive-only portion of the receive path or a transmit-only portion of the transmit path. The amounts of attenuation provided by the first and second attenuators are decoupled such that a different amount of attenuation can be provided on the transmit path than on the receive path. Performance of forward and reverse links of the system are measured while varying a value of at least one of the first or second attenuators. For a given measurement, the attenuator values may be selected to simulate performance of the system in a configuration in which base station amplifier power is increased or decreased. As another example, the attenuator values may be selected to simulate performance of the system in a configuration in which cell size is increased. This arrangement of decoupled forward and reverse link attenuation in accordance with the invention permits efficient and accurate determination of link balance conditions.
