摘要： In providing a wireless location communication service including a location based service to a user of a mobile device, the mobile device sends information concerning a location of the device relative to a given position in a wireless communication system. The given position may be that of a base station in the system. First information concerning a location of the base station (e.g, GPS information) is communicated to the mobile device, e.g., via broadcast. The mobile device determines second information concerning its location, e.g., based on signals from GPS satellites received thereby. The mobile device then generates relative location information based at least on the first and second information.

摘要： A method and apparatus to quickly adjust a targeted Eb/N0 in a wireless communication system by using an effective Eb/N0 for each frame. The Eb/N0 distribution of a frame produces a certain frame error rate. Effective Eb/N0 is the Eb/N0 that would produce the same frame error rate in a model channel, such as an additive white Gaussian noise (AWGN) channel. The effective Eb/N0 for each frame is obtained and compared to a model targeted Eb/N0. The Eb/N0 for all of the power control groups in one frame compose the vector Eb/N0. The effective Eb/N0 for the frame is obtained by mapping a vector Eb/N0 into a scalar. The model targeted Eb/N0 is the Eb/N0 value that produces a desired frame error rate in the model channel. The targeted Eb/N0 is increased by one up step size when the effective Eb/N0 is smaller than the model targeted Eb/N0 and is decreased by one down step size when the effective Eb/N0 is larger than the model targeted Eb/N0. Eb/N0 are measured for each power control group in a frame. The wireless communication system includes a transmitter to transmit a signal, a receiver to receive the signal, and an outer control loop to adjust the targeted Eb/N0 based on a comparison of the effective Eb/N0 of the signal to the model targeted Eb/N0. Preferably, the outer control loop is implemented in software, although it can be implemented in hardware. Obtaining an effective Eb/N0 for each time period allows quicker adjustments of the targeted Eb/N0. This permits the targeted Eb/N0 to be closer to an Eb/N0 that produces a desired frame error rate, especially if the mobile is moving. This allows the transmitted power to be closer to the power needed to produce the desired frame error rate, permitting an increase in the capacity of the wireless communication system while still maintaining an acceptable number of errors.

摘要： A mobile telecommunication system power control loop includes a symbol error rate detector to detect a number of symbol errors induced during transmission, a summing node to subtract the output of the symbol error rate detector from a symbol error rate target, a multiplier to introduce an adjustment factor, and an integration element to sum the output of the multiplier with past outputs of the multiplier. The output of the integration element is a signal power to noise power ratio target which is used to control the transmission power of the mobile telecommunication system. In one embodiment the symbol error rate target is a constant or parameter set by the user. In another embodiment the symbol error rate target is adjusted automatically to maintain a constant frame error rate.

摘要： A method of handoff utilizing a combined signal quality measurement to trigger or initiate a handoff of a mobile station to a plurality of neighbor base stations, wherein the combined signal quality measurement corresponds to a summation of signal quality measurements associated with the plurality of neighbor base stations. The handoff is triggered when the combined signal quality measurement is greater than a handoff threshold. By using the combined signal quality measurement instead of a signal quality measurement of an individual neighbor base station, handoffs can be triggered earlier along a boundary shared by neighbor cells, thereby reducing interference associated with later triggered handoffs. When triggered, the mobile station is handed off to a plurality of neighbor base stations allowing the mobile station to establish simultaneous communication links with two or more neighbor base station. This increases the chance that at least one of the communication links or the combination thereof is a strong communication link, thereby improving the reliability and success rate of handoffs.

摘要： A system is implemented on a wireless network for adjusting a forward link power control parameter based on forward link feedback. A wireless unit is in communication with several base stations during soft handoff, and provides feedback relating to forward link quality, e.g., forward link pilot signal strength or traffic channel frame error rate. The feedback is compared to a comparison or reference point (such as target frame error rate, or a maximum pilot signal strength in the active set) chosen for gauging the quality or nature of the feedback for power control purposes. Based on this comparison, a power control parameter of one or more of the base stations may be adjusted upwards or downward. The power control parameter may be a forward link reference transmit power level “Pref” used to control base station power transmission levels in the presence of power control bit errors.
