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： An access terminal in a coverage area of an access network may be monitoring a level of loading on the coverage area's reverse link, such as by monitoring a series of reverse activity bits sent by the access network. The access terminal may then detect new data for transmission to the access network and responsively select a reverse-link data rate based on the monitored level of loading. In this respect, the access terminal may select (a) a first data rate (e.g., a reverse-link data rate at which the access terminal last transmitted data) if the access terminal detects a low load, and (b) a second data rate (e.g., a minimum available reverse-link data rate) if the access terminal detects a high load, where the second data rate is lower than the first data rate. The access terminal may also consider its location in selecting the reverse-link data rate.

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 mobile station that is being served by a current sector receives a neighbor list that identifies a plurality of neighboring sectors and a respective priority for each neighboring sector. For each neighboring sector, the mobile station scans for the sector's pilot signal at a respective scanning frequency during a measurement interval. The scanning frequency for a sector defines how frequently the mobile station scans for the sector's pilot signal during the measurement interval. The mobile station selects a scanning frequency for a neighboring sector based on at least a signal strength of the current sector and the neighboring sector's priority. When the current sector's signal strength is high, the mobile station scans for high-priority sectors more frequently than low-priority sectors. When the current sector's signal strength is low, the mobile station scans for low-priority sectors more frequently than high-priority sectors.

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.
