摘要： A method and system is disclosed for dynamically adapting operation of an auxiliary pilot according to reverse noise. An access terminal in a wireless communication system that includes a base station may operate in a first state in which the access terminal transmits a primary pilot signal on an air interface communication link to the base station, and also transmits an auxiliary pilot signal on the air interface communication link to the base station concurrently with transmission of the primary pilot signal. While operating in the first state, responsive at least to receiving a noise-level message from the base station indicating excessive reverse-link noise, the access terminal may transition to a second state in which it ceases to transmit the auxiliary pilot signal but continues to transmit the primary pilot signal.

摘要： A mobile station transmits a message by transmitting an access probe that includes the message preceded by a preamble. The mobile station selects the length of the preamble from among a first preamble length and a second preamble length. The second preamble length is greater than the first preamble length. The mobile station makes the selection based, at least in part, on the distance between the mobile station and the mobile station's primary base transceiver station (BTS). If the distance is greater than a threshold distance, the mobile station selects the second preamble length. If the distance is less than the threshold distance, the mobile station selects the first preamble length, provided that an idle handoff to a neighboring BTS that is more than the threshold distance away is unlikely.

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 enhanced idle-state sector selection during hybrid-mode operation of an access terminal. A hybrid access terminal engaged in an IS-856 data communication session in a hybrid IS-2000/IS-856 wireless communication system will, responsive to a handoff of the IS-856 session, select a sector for its next, upcoming IS-2000 idle-state scan prior to the start of the scan. The selection will be made during an interval between IS-2000 idle-state scans, thereby reducing or eliminating the possible need for idle-state handoffs during idle-state scans, and resulting in shorter idle-state scans and better IS-856 performance.

摘要： Systems, methods, and computer-readable media for adjusting a timer mechanism based on radio frequency (RF) conditions of a network connecting source and destination devices are provided. Initially, data packets transmitted by the source device are assigned an ordering. This ordering is compared to an actual order in which the data packets are received at the destination device to ascertain whether any data packets were missing due to RF conditions. A negative response indicating missing, or lost, data packets may be returned, thereby invoking the source device to retransmit the data packets identified as missing. The device(s) may compute a probability of packet-loss (utilizing a recorded history of the transmitted packets in conjunction with the data packets actually received) and utilize the packet-loss probability to dynamically tune a time-interval of the timer mechanism. Upon expiration of the time-interval, the timer mechanism instructs the source device to retransmit the initial data packets.

摘要： A method is disclosed for implementing an overlay carrier frequency in a wireless coverage area in response to low load in the coverage area. Normally, an carrier frequency may be added in response to high load. However, the disclosed method involves adding a carrier frequency in response to low load, as the addition of a carrier may advantageously increase the likelihood of soft handoff in certain situations, and as low load may facilitate operation on the added carrier without the need to add expensive supporting infrastructure that would typically be added to support full operation on an added carrier frequency.

摘要： Methods and systems provide dynamic determination of a control-channel bit rate. An access node provides service on a carrier comprising active and idle timeslots, active timeslots comprising a data channel for carrying a control channel at a bit rate that can be set to a lower value or a higher value, and traffic channels. The access node determines whether the number of active timeslots over a time period is less than a first threshold. If so, the access node sets the bit rate to the lower value. If not, the access node sets the bit rate to the higher value if at least one of the following is true: (a) control-channel occupancy exceeds a second threshold, (b) the amount of data in a traffic buffer exceeds a third threshold, and (c) control-channel occupancy exceeds a fourth threshold and the amount of data in the traffic buffer exceeds a fifth threshold.

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： A method of selecting a type of resource-allocation to use for a call in a cellular wireless system, such as selecting a type of radio configuration to use for the call. According to the method, resource-availability in one more adjacent coverage areas may be used as a basis to select the type of resource-allocation to use in a current coverage area. For instance, given the choice between a radio configuration that consumes less base station power and a radio configuration that consumes more base station power, the radio configuration consuming more base station power may be selected if base station sufficient power is available in one or more adjacent coverage area(s), and the other radio configuration may be selected if insufficient base station power is available in the one or more adjacent coverage area(s). Distance between the mobile station and a current base station may be considered as well.

摘要： A mobile station uses a search window to search for a target pilot signal transmitted by a target transmitter in a spread spectrum communication system. The search window may be centered on the expected phase of the target pilot signal at the mobile station. To calculate the expected phase, the mobile station estimates a transmission delay associated with the target pilot signal, based on at least the target transmitter's location and the mobile station's location. The transmission delay may account for the time it takes for the target pilot signal to propagate from the target transmitter to the mobile station. The expected phase of the target pilot signal may then be calculated based on at least a nominal phase of the target pilot signal (e.g., the phase when transmitted by the target transmitter) and the estimated transmission delay.
