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： 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： 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.
