A method for substantially reducing the frame erasure rate (FER) to approximately 1 percent dynamically changes the power down to power up ratio from 100 to 1 to 200 to 1 to minimize subsequent frame erasures. During call startup periods the method () loosely monitors the power. Whereas for consecutive error bursts of frame erasures, the process () does not change the power threshold. This power threshold is the level received signals are compared against to determine if a power up or a power down step needs to be performed. Likewise, RF fades will not cause the power threshold to be increased. Further, should the power threshold exceed its maximum, it is reset by process ().

The present invention relates to a method and a system for handling one or more soft handoff (SHO) requests from one or more mobile stations in a wireless communication system. The method comprises determining a set of parameters corresponding to each SHO request corresponding to each mobile station. The method further comprises processing each SHO request corresponding to each mobile station based on the set of parameters corresponding to each SHO request.

A method, device and computer-readable storage element for dynamically changing a maximum access channel rate at a site in a communication system. The method includes setting a maximum access channel rate for an access channel at a site, which comprises a coverage area for a base station. The method further includes determining a first access probe success rate that measures a rate at which first attempt access probes sent from the terminals on the access channel are received, and changing the maximum access channel rate based on the first access probe success rate.

A method and Node B are disclosed for allocation of “sticky” resources in an Orthogonal Frequency Division Multiplexing communication system. The Node B comprises a scheduler that is configured to make a sticky resource allocation to a user equipment, determine that a transmit power level allocated for transmissions to the user equipment should be adjusted, determine whether the resources allocated to the user equipment comprise a Quadrature Phase Shift Keying (QPSK) modulation scheme, and in response to determining that the resources allocated to the user equipment comprise a QPSK modulation scheme, adjust the allocated transmit power level without informing the user equipment of the adjustment. The Node B further may condition the determination to adjust the allocated transmit power level without informing the UE of the adjustment based on a size of the adjustment.

A power control method () is applicable either to a base station or a mobile station (-N). This method takes into account the previous two power control bits (-). The method then determines a correction factor by multiplying the power control step size by the sum of the previous two power control bits (). A corrected received signal is produced () and compared to a threshold signal (). Based on this comparison, power control is set up () for data frames below the signal threshold or power is set down () for data frames equal to or above the signal threshold.

A mobile unit which is in a soft handoff condition with a base station () has the power transmitted by the base station () on the mobile link () controlled. The base station () determines () when a frame erasure count reaches a particular level N. The base station then places this link in a clamped state () at minimum power. When the base station determines that M consecutive good frames have been received (), the base station restores the link () to a normal state (). A recovery arrangement (and ) prevents clamping by all base stations (-) and loss of the link.

A method and apparatus of managing an active set of a mobile station in a soft-handoff environment includes for a reverse link, comparing a reverse link quality metric to a reverse link quality threshold, where the reverse link is associated with a base station in the active set, and determining an aggregate reverse link quality metric corresponding to at least one base station that is a member of the active set but is not under consideration to be dropped from the active set. If the reverse link quality metric is below the reverse link quality threshold for a time period, the aggregate reverse link quality metric is compared to an aggregate reverse link quality threshold, and if the aggregate reverse link quality metric compares favorably to the aggregate reverse link quality threshold, the base station is removed from the active set.
