摘要： Disclosed is a method and apparatus for dynamically varying the amount of time a hybrid access terminal operates on a first air interface protocol between instances of temporarily switching over to scan a second air interface protocol for broadcast information such as network operational parameters or page messages. The hybrid access terminal dynamically sets a minimum interval of operation on the first air interface protocol based on how long the access terminal has tended to be temporarily switched away to scan for broadcast information on the second air interface protocol. For example, as the switch-away time increases, the access terminal may increase the interval on the first air interface protocol, and as the switch-away time decreases, the access terminal may decrease the interval on the first air interface protocol.

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： 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： Methods and apparatus are provided for a wireless communication device (WCD) to utilize one or more search windows to capture both an earliest-received signal and a strongest received signal. In an embodiment, in a first time period, the WCD detects an arrival time of an earliest-received signal and an arrival time of a strongest received signal in one or more search windows for each of at least one set of signals. The WCD then centers a first search window based on the arrival time of the earliest-received signal and centers a second search window based on the arrival time of the strongest received signal for each of the at least one set of signals. In a second time period, the WCD searches for signals using the first and second search windows.

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.
