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.

Method and apparatus for resource allocation in an orthogonal frequency division multiplexing communication system

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.

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.

Method and system for handling soft handoff in a wireless communication system

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 ().

Power control method for handling frame erasure of data in mobile links in a mobile telecommunication system

A mobile unitwhich is in a soft handoff conditionwith 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.
