摘要： During a first time interval, an access point transmits orthogonal frequency division multiplexing (OFDM) signals using a first cyclic prefix length. The access point receives a plurality of signal reports, such as Channel Quality Indicators (CQIs), from user devices being served by the access point. Based on the signal reports, the access point determines a distribution of signal qualities experienced by the user devices. The access point selects a second cyclic prefix length based, at least in part, on the distribution of signal qualities. The access point transmits OFDM signals using the second cyclic prefix length during a second time interval.

摘要： Systems and methods for dynamically adjusting a metric that influences power management of an access terminal are provided. Initially, an access node is configured to distribute reverse-activity bits (RAB's) to the access terminal, which conveys data, at a particular rate, to the access node. Adjusting the dynamic metric involves establishing a number of slots allocated for a filtered reverse-activity bit (FRAB) window and a hybrid reverse-activity bit (HRAB) window, wherein each of the slots are allocated to accept a RAB. The RAB's accepted to the slots of the FRAB window and the HRAB window are recursively averaged to derive a FRAB parameter and an HRAB parameter, respectively. The dynamic metric is adjusted by incorporating either the FRAB parameter or an HRAB parameter therein based on whether ramping conditions are satisfied. The rate of data conveyed from the access terminal is controlled based on the adjusted dynamic metric.

摘要： A method and system for monitoring data rate requests (DRRs) transmitted from an access terminal (AT) to an access network (AN). Each DRR includes a parameter indicating whether it is a null or non-null DRR. Upon the AT transitioning to a null-DRR state, the AT and AN determine an average parameter of a given number of DRRs and compare the average to a threshold. The AT selects a time duration based on the average and starts a timer. When the timer counts to the selected duration, the AT transitions from a mode in which the AT transmits data channel traffic and other traffic to a mode in which the AT prevents transmission of data channel traffic but allows transmission of other traffic. The AN compares the average to another threshold and determines whether it should transmit forward-link traffic channel data to the AT at a null or non-null data rate.

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 system is disclosed for selectively scheduling control channel messages ahead of traffic channel data. When a RAN in a wireless communication system operating at least according to IS-856 determines that a delay condition exists in the transmission of a particular control packet to access terminals, the RAN will determine if there is a particular traffic packet in active transmission that is classified according to best effort service (or similarly-characterized service class), and further if at least a threshold number of a nominal number of time-slot segments of the particular traffic packet remain untransmitted. If such a traffic packet is identified, the RAN will cancel transmission of the particular traffic packet and replace it with immediate transmission of the particular control packet.

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 method and system is disclosed for dynamic adjustment of forward-link rate-control parameters. An access terminal in a wireless communication system that includes a base station will determine a requested forward-link data rate by measuring a signal-to-noise ratio (SNR) of the forward link, and looking up a corresponding forward-link data rate in one of three different tabulations of SNR threshold values against forward-link data rates. The AT will operate in a first state in which the access terminal uses a single tabulation for both increasing and decreasing measurements of SNR, and upon receiving a message from the base station indicating high time slot utilization on the forward link, the AT will transition to operating in a second state in which the access terminal uses a dual tabulation, wherein one of the dual tabulations is used for increasing measurement of SNR, and the other is used for decreasing measures of SNR.
