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 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： 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： 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 spread spectrum communication system includes a base station that is able to transmit wireless signals that are spread by any of a plurality of orthogonal spreading codes and receive wireless signals that mobile stations transmit in an access channel. One of the orthogonal spreading codes is reserved as an indicator code that the base station uses to indicate when the access channel is occupied by a transmission from a mobile station. When the base station detects a transmission in the access channel, the base station estimates a completion time when the transmission will be completed and transmits an indicator signal spread with the indicator code until the completion time is reached. Before a mobile station transmits a message in the access channel, the mobile station determines whether the access channel is occupied by determining whether the base station is transmitting the indicator signal.
