摘要： Methods and systems are provided for conducting power control based on reverse-link RF conditions. In an embodiment, a base station periodically calculates a reverse noise rise (RNR), periodically calculates a collective reverse-link frame error rate (RFER), and periodically checks whether a new call-origination message has been received. If a call origination has not been received, the base station checks whether the RNR is less than a threshold. If the RNR is less than the threshold, the base station sends power-up commands to each of mobile stations. If the RNR is not less than the threshold, the base station sends power-down commands to each of the mobile stations so long as the collective RFER is less than a maximum RFER. If a call origination has been received, the base station sends power-down commands to each of the mobile stations until the collective RFER reaches the maximum RFER.

摘要： A mobile station receives a target pilot signal transmitted by a target transmitter in a spread spectrum communication system and measures its phase. The mobile station then defines a search window to search for the target pilot signal at a later time. The mobile station defines the center point of the search window based on the previously-measured phase and the mobile station's direction of motion and speed relative to the target transmitter. If the mobile station is moving toward the target transmitter, the center point is less than the previously-measured phase by an adjustment amount. If the mobile station is moving away from the target transmitter, the center point is greater than the previously-measured phase by an adjustment amount. The adjustment amount may depend on the mobile station's speed. After the search window is defined, the mobile station uses the search window to search for the target pilot signal.

摘要： A method for selecting a wireless coverage sector to serve a mobile station, such as in response to a handoff request that designates a sector-identifier that represents two or more possible sectors. A serving radio access network (RAN) may identify potential sectors in the region and may then select the sector whose azimuth is closest to the geographic bearing of the mobile station from the sector's base station. Further, in the event of a tie between two or more sectors or in other circumstances, the RAN may also take into consideration how close the mobile station is to various base stations, such as selecting the sector to whose base station the mobile station is closest. In a system that uses neighbor lists to govern handoff, the invention can help to facilitate handoff in a scenario where a mobile station requests handoff to a sector not listed in the mobile station's neighbor list.

摘要： A method and apparatus for selecting channel elements in a wireless communication system based on their performance history. Data is collected indicating the performance of various channel elements over time, preferably eliminating from consideration any performance degradation due to air interface (e.g., radio frequency) issues. The data is then used to sort the channel elements in a priority order, from best-performing to worst-performing. When a channel element is to be selected for use in connection with an air interface channel (e.g., traffic channel or control channel), the channel element is then selected in accordance with the priority order, such as by selecting the channel element that has performed best over time. The priority-based selection of channel elements can thus leave poor-performing channel elements for use as a last resort, which can be advantageous in times of heavy network loading for instance.

摘要： A method and system is disclosed for dynamically adjusting a signal-to-noise (SNR) bias based on relative load between a macro type base station and a micro type base station of a wireless communication system. The SNR bias corresponds to a threshold differential SNR between SNRs of the macro base station and of the micro base station, wherein the SNR bias is configured to be provided to an access terminal (or user equipment) to cause the access terminal (i) to be biased to seek service from the micro base station if the access terminal detects an SNR from the micro base station that is less than the threshold differential SNR below an SNR that the access terminal detects from the macro base station, and (ii) to be biased to seek service from the macro base station otherwise. Once the SNR bias is determined based on the relative load, it is communicated to one or more access terminals.

摘要： A first serving system controls a first group of sectors that transmit pilot signals having pseudonoise (PN) offsets corresponding to a first PN increment, and a second serving system controls a second group of sectors that transmit pilot signals having PN offsets corresponding to a second PN increment. The first serving system serves a mobile station via a sector in the first group and determines that the mobile station is likely to be in a communication range of at least one sector in the second group. In response, the first serving system instructs the mobile station to use the second PN increment when scanning for pilot signals. Thereafter, the mobile station may use the first PN increment to scan for pilot signals to add to its remaining set and, if the remaining set is not large enough, may then use the second PN increment to scan for additional pilot signals.
