International Classification:

H04Q 7/20

US Classification:

455450, 455453, 455436, 455433, 455509, 455553

Abstract:

A method of processing, in parallel fashion, messages from a User Equipment (UE) in soft handoff with a plurality of base stations of a wireless communication system. Measurement Messages from the User Equipment are received and stored in a message buffer for a defined period of time. Later arriving messages replace previous messages during the defined period of time. When the defined period of time elapses, the latest stored message is processed in parallel fashion in a processing pipeline with other messages for the UE and other UEs. The latest message is processed by first converting it to soft handoff actions and inserting such actions into a processing pipeline. A conflict table is generated during the parallel processing of the soft handoff actions to avoid the processing of messages that conflict with each other. Conflicting messages are put into a pending state and remain in such state until they are canceled by subsequent messages or the conflict no longer exists.

International Classification:

H04W 4/00

US Classification:

370332, 455 69, 455522

Abstract:

In an aspect of the method, a received data packet is decoded in order to determine a packet error rate value, and an average package error value for N received data packets is updated based on the determined packet error rate value. The updated average packet error rate value is then compared against a threshold value and a data rate request is issued based on this comparison. In another aspect, a response to a transmitted data packet is received, the response being related to an average packet error rate value. The average packet error rate value is compared against a threshold and a data rate is modified based on the comparison. In each of the above aspects, a data rate control margin that is used to overcome channel estimate errors resulting from transmission delays may be dynamically adjusted, e. g. , in real time, in order to optimize system resources.

International Classification:

H04L 27/06

US Classification:

375267, 455101

Abstract:

A method and system for predicting a signal power to interference metric for a communication channel in a coverage area of a phase sweep diversity communication system are provided. In the method, a signal power to interference metric for the communication channel is predicted based on a sweep frequency for transmissions in the coverage area. The signal power to interference metric predicted may be a carrier-to-interference ratio or a signal-to-noise plus interference ratio.

International Classification:

H04W 24/00
H04M 11/04

US Classification:

4554561, 4554042, 4554563

Abstract:

A method for estimating a geographic location of a mobile station within a coverage area of a wireless network includes: determining a radial distance of the mobile station from a serving base station based on a round trip measurement and calculating an angular position of the mobile station in relation to the radial distance based on a first signal strength measurement, a second signal strength measurement, and an angular position reference that extends outward from the serving base station. The signal strength measurements representative of power characteristics of RF signals received by the mobile station from first and second sector antennas of the serving base station. An apparatus associated therewith includes a distance module to perform the determining and an angular position module to perform the calculating. The apparatus may be implemented in a base station, a geo-location service node, a network management node, or other communication nodes.
