    摘要: Disclosed are methods for determining which page attempt to shed. In accordance with these methods, when a page attempt from a first sequence directed to a first access terminal (AT) contends with a page attempt from a second sequence directed to a second AT for transmission over the air interface of a RAN, the RAN determines which sequence has been shed to a greater extent. The RAN then transmits the page attempt from the sequence that has been shed to a greater extent and sheds the page attempt from the sequence that has been shed to a lesser extent. The methods advantageously help to avoid one sequence of page attempts being disproportionately shed.

    摘要: A method and system is disclosed for shifting the phase of a PN long code for access attempts by an access terminal in a wireless communication network. An access terminal may seek to acquire access from a base station that is detected by the access terminal above a threshold power level, even if the access terminal is further away from the base station than a threshold distance beyond which access is not normally granted. According to one embodiment, the access terminal will, upon determining that it is beyond the threshold distance, embed in an access request message an apparent distance that is smaller than the threshold distance, by phase-shifting a timing signal and encoding the access request message with the phase-shifted timing signal. The access terminal will then transmit the access request message on an air interface communication link to the base station.

    摘要: A method and system is disclosed for dynamic adaptation of reverse-link power control based on the distribution of ATs implementing different protocol versions. An access terminal in a wireless communication system that includes a base station may operate in a first state in which, at least, the access terminal uses a first protocol for determining and adjusting transmission power on a reverse link of an air interface with the base station. While operating in the first state, responsive to receiving a protocol version message from the base station on a forward link of the air interface, the access terminal will transition to operating in a second state in which, at least, the access terminal uses a second protocol for determining and adjusting transmission power on the reverse link of the air interface with the base station. The first protocol is different from the second protocol.

    摘要: A mobile station and a radio access network (RAN) use a single-channel forward link and a single-channel reverse link for a communication session. If the quality of the communication session degrades, the single-channel forward link is replaced with a multi-channel forward link and/or the single-channel reverse link is replaced with a multi-channel reverse link. The multi-channel forward link may include a first forward link channel and a second forward link channel, each with a higher coding gain than that of the single-channel forward link, to provide an aggregate data rate that is substantially the same as that of the single-channel forward link. The multi-channel reverse link may include a first reverse link channel and a second reverse link channel, each with a higher coding gain than that of the single-channel reverse link, to provide an aggregate data rate that is substantially the same as that of the single-channel reverse link.

    摘要: Methods and apparatuses are provided for identifying and selectively controlling reverse-noise contribution on a per-access terminal basis. In an embodiment, an access node provides wireless service to access terminals, and measures reverse noise rise (RNR) during at least one turn of a round-robin process involving access terminals taking turns transmitting data or taking turns not transmitting data. The access node thereby determines a respective RNR contribution of at least one access terminal based at least on the measurement of RNR taken during the access terminals' turns. A high-contributor set of one or more access terminals is identified and then instructed to reduce reverse-link transmission power.

    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: 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: 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.

    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.
