摘要： An improved mechanism for managing allocation of air interface timeslots for transmission of data to access terminals. When an access terminal requests an access network to transmit data to the access terminal in a first sector, the access terminal will identify within its request a second sector that the access network can optionally use instead. The access network will then determine whether a threshold number of upcoming timeslots in the first sector are already scheduled to carry data to other access terminals and whether at least one of those timeslots is available for use in the second sector. If so, the access network will then responsively transmit the data to the access terminal in the at least one timeslot on the second sector. Advantageously, this process can help to increase sector throughput.

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： Disclosed herein is a method and system to help manage transmission power for wireless communications. A radio access network (RAN) will artificially increase target frame error rate (FER) for certain mobile stations in a coverage area for just a portion of a defined call drop timer period, and the RAN will automatically revert to apply a baseline target FER for a duration sufficient to allow recovery of the mobile station's communications before expiration of the call drop timer period. By increasing the target FER for the mobile stations, noise on the air interface can be reduced. And by reverting the target FER to its baseline level for a sufficient duration, call drops resulting from the increased target FER can be avoided.

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： Methods and systems for adjusting a transmit power of a forward link or reverse link signal make use of variable adjustment parameters. The wireless signal is received to obtain a received signal. An observed signal-to-noise ratio (SNR) and an observed frame error rate (FER) for the received signal are determined. In an outer loop process, an adjustment increment is selected based on how much the observed FER differs from the target FER, and the target SNR is adjusted by the adjustment increment. In an inner loop process, a power adjustment command is selected based on a comparison between the observed SNR and a target SNR. The power adjustment command instructs the transmitter of the wireless signal to either increase or decrease the transmit power of the wireless signal. The power adjustment increment may also depend on the observed FER.

摘要： Methods and computer-readable media are provided to enable the selection of a cell tower sector that is used by the mobile device to provide higher quality signals in a current frame. Signal quality data is retrieved for a previous quantity of frames, and indicates the signal quality of signals communicated from multiple sectors to a mobile device during soft handoff. A sector that has been communicating higher quality signals is then selected. Loading, signal-to-noise ratio, and a number of traffic channels may be used independently or in conjunction to determine which sector to select. For time slots of a current frame, an overall power control command is communicated to each sector that corresponds to a power control command assigned to the selected sector.
