A method for controlling downlink power in a time-division multiplex wireless system may provide different downlink transmit signal powers to different time-division multiplex channels of a single carrier. A base station receives a measured signal parameter data for a downlink transmit signal of a time-division multiplex channel. The base station determines an initial adjustment for the downlink transmit signal power of the time division multiplex channel if the measured signal parameter data differs from a target signal parameter data. The base station determines a revised adjustment for the downlink transmit power of the time division multiplex channel based on the initial adjustment and at least one adjustment range as appropriate to achieve synchronization of the demodulation of the downlink transmit signal.

A computer implemented method and apparatus that schedules broadcast short message service (BSMS) messages in a manner that reduces the adverse impact on voice quality and system capacity, attributable to the transmission of the BSMS messages, in a wireless telecommunications system. The method and apparatus utilize a quality of service (QoS) based broadcast message scheduler to negotiate and schedule the transmission times of BSMS messages to the individual users in the system. The quality of service (QoS) based broadcast message scheduler also allows a user to tradeoff voice quality for broadcast capacity.

The present invention, in illustrative embodiments, implements systems and methods for adjusting the timing of access requests in mobile communications systems, such as IS-95-A mobile telephone systems, to reduce the likelihood of request collisionsâespecially during periods of very high calling rates. These embodiments employ measurements of access channel occupancy, as well as system operator inputs, to develop thresholds and parameter translations at a base station. Execution of control algorithms at a base station advantageously yields modified persistence test parameters sent to mobile stations. When overload conditions are present, these modified parameters cause the mobile stations to experience variable delays through judicious control of persistence testing at the mobile stations.

Disclosed is a method for improving call quality and capacity by integrating a dynamic channel allocation technique into an intelligent antenna system. The intelligent antenna systems includes beams which are grouped into sets, wherein each set has associated a long list and a primary short list, and each beam has associated a secondary short list. In one embodiment, long term interference levels are measured on each beam in a set of beams for a plurality of communication channels to produce the long list; short term interference levels are measured on each beam in the set of beams for a portion of the plurality of communication channels to produce a plurality of secondary short lists and the primary short list; and communication channels are assigned to a mobile-station from the portion of the plurality of communication channels based on the measured short term interference levels on each beam in the set of beams. The long list and the primary short list are based upon highest measured long and short term interference levels, respectively, for each of the plurality of communication channels across each beam in the set of beams.

In the method according to the present invention, a signal from a mobile station is received. The standard deviation of the symbol error rate is determined, and power control with adaptive adjustment of an amount of change in the target signal-to-noise ratio is performed based on the determined standard deviation of the signal error rate and a target associated therewith.

A code-division multiple access power control for paging channel power and initial traffic channel power dynamically determines optimum initial channel power in accordance with pilot signal strength of a pilot signal as received at a mobile station and current forward link loading of the desired sector. The optimum initial paging channel power and initial traffic channel power may be determined either at a base station or a mobile switching center of the mobile communication system. A paging signal or call is transmitted from the base station to the mobile station over a paging channel and a traffic channel at the optimum paging channel and initial traffic channel power.

The present invention provides a method and an apparatus for a wireless communication between a base station and at least one mobile station. The method includes receiving a request for a data rate from the mobile station on a reverse link channel to the base station. The method further includes, in response to the request, skipping a first slot after a delay for a portion of a slot on a forward link transmission before transmitting a data packet in a second slot. By beginning the forward link transmission at the start of the second slot, for example, a software module may cause the base station to skip a slot immediately after the half slot delay. This additional delay of one slot or a portion of the slot may expand radius of a cell for a wireless communication between the base station and the mobile station in a relatively high-speed wireless data network.

An interference based dynamic channel assignment scheme for a wireless communication network, for self configuring dynamic channel assignment of a plurality of channels, comprises the steps of: prioritizing a channel list and prioritizing a selected subset of the prioritized channel list. In further enhancements of the present invention, prioritizing a channel list is distributed on a per cell/sector basis so that prioritization is independent of frequency usage information from other cells/sectors and prioritization is based upon uplink and downlink characteristics.
