A method that adjusts the power level of a set of forward-link signals of a base station responsive to the loading of the forward link as determined by a power level measurement of the signal set. One power level measurement is a pilot fraction of the forward link. Other power level measurements, such as the signal sets power level, can be used, alone or in combination, instead of or in addition to the pilot fraction of the forward link to adjust the power level of the signal set. The power level of the signal set can be changed in any manner, including by scaling it by a scaling factor, or by increasing the power level by a fixed or a variable amount. The power level measurement of the signal set is obtained during a current time period. The scaling factor that will be used in the subsequent time period is determined using the power level measurement. In one embodiment of the invention, the scaling factor can be obtained from a look-up table that is based on the power level measurement.

A method for determining the initial power to be allocated to a secondary channel having a desired data rate. An SNR setpoint is first calculated where such setpoint is based on the SNR setpoint of the associated primary channel and system offset values. The initial power is then calculated based on the calculated setpoint.

A method and apparatus for estimating the initial power level and transmission rate of a burst on a secondary channel when the secondary channel is on fewer legs of a handoff, such as a soft or softer handoff, than the primary channel. In accordance with the present invention, the initial power level of the burst transmitted over a current secondary channel on a particular leg(s) is a function of a power level of a previous burst transmitted over a previous secondary channel on the identical leg(s) as the current secondary channel. For example, the initial power level of the burst can be based on the power level at the end of the previous burst shortly prior to the termination of the previous burst, where the termination of the previous burst was within a predetermined time interval of the start of the burst. Optionally, the initial power level of a burst can also be additionally adjusted based on characteristics of the communication link of the primary channel, the previous secondary channel, and the current secondary channel. The transmission rate may then be adjusted based on the initial power level determined as described above to obtain a more efficient transmission rate.

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.

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.

A system and a method for reverse link power control in a wireless communications network generates power adjust commands for mobiles being served by a network base station in a centralized manner by considering overall system performance when an increased interference condition is detected. In one implementation, a base station power control processor adopts a modified reverse inner loop power control (RILPC) and/or a reverse outer loop power control (ROLPC) algorithm when an increased interference condition is detected. According to the modified RILPC algorithm, a percentage of power-up adjust commands which would normally be generated when E/Nmeasurements for served mobiles do not meet target E/Nlevels are converted to power down-adjust commands, thereby forcing some mobiles to reduce transmit power, at least temporarily, to constrain interference. When the increased interference condition persists, the percentage of power-up adjust commands which are converted to power-down commands may be changed. According to the modified ROLPC algorithm, the power control processor adjusts target E/Nlevels in a centralized manner based on an overall system state so that only a limited number of target E/Nlevels are allowed to increase when frame erasures occur.

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.

A method of applying one of several resource distribution algorithms to an incoming call to a communication system. The applied resource distribution algorithm is based on resource parameters obtained from a main scheduler of the communication system. Some of the resource parameters include the type of call, the resource usage and the resource allocation scheme. The resource parameters generally describe the amount of resources that are currently being used by the system and which resources are available to the incoming call. The method of the present invention admits the incoming call to the communication system in accordance with one of the resource distribution allocation schemes. In this manner, the resources of the communication system can be efficiently and fairly distributed to different types of users requesting admission to the communication system.
