    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: 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.

    摘要: Methods and systems use traffic channels to extend wireless coverage areas. In an embodiment, an access node transmits a standard pilot signal over a pilot channel. The access node initially operates in a standard transmission mode, wherein the access node transmits a standard traffic signal over a traffic channel at a first power level. The access node makes a determination to operate in an alternative transmission mode involving the access node generating and transmitting a modified traffic signal comprising (i) a standard traffic signal and (ii) a modified pilot signal. The access node transmits the modified traffic signal at a second power level that is greater than the first power level.

    摘要: Methods and apparatus are provided for adjusting a forward-link power-control step size. An initial active set of coverage areas for a mobile station is maintained within which a first coverage area in the initial active set has a signal strength that is stronger than that of each of the other coverage areas in the initial active set. The first coverage area is determined to have dropped from the initial active set, resulting in a modified active set. In response, a signal-strength factor is calculated based on (a) a last non-zero signal-strength measurement of the first coverage area and (b) a second value. One or more forward-link power-control step sizes is selected based on at least the calculated factor. The one or more selected step sizes is used to increase the forward-link transmission power of at least one coverage area in the modified active set.

    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.

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.
