摘要： A mobile station receives a target pilot signal transmitted by a target transmitter in a spread spectrum communication system and measures its phase. The mobile station then defines a search window to search for the target pilot signal at a later time. The mobile station defines the center point of the search window based on the previously-measured phase and the mobile station's direction of motion and speed relative to the target transmitter. If the mobile station is moving toward the target transmitter, the center point is less than the previously-measured phase by an adjustment amount. If the mobile station is moving away from the target transmitter, the center point is greater than the previously-measured phase by an adjustment amount. The adjustment amount may depend on the mobile station's speed. After the search window is defined, the mobile station uses the search window to search for the target pilot signal.

摘要： A method and system is disclosed for enhanced Simultaneous Hybrid Dual Receive operation. A hybrid access terminal engaged in an IS-856 data communication in a hybrid IS-2000/IS-856 wireless communication system will use its high-gain antenna to conduct IS-2000 tuneaway scans when the access terminal determines that the IS-2000 signal received from its serving base station is below a level that can be reliably detected by its low-gain antenna. At the same time, the access terminal will continue to use its low-gain antenna to engage in the ongoing IS-856 communication, thereby avoiding interruption of the IS-856 communication by IS-2000 tuneaway scans, even when RF conditions are sub-optimal. The access terminal may apply a DRC offset to its DRC request when using just its low-gain antenna for IS-856 communications.

摘要： In methods and systems for adjusting forward link transmit power of wireless coverage areas, forward link signal strength is observed to obtain a signal-to-noise ratio (SNR) and/or an observed frame error rate (FER) for the received signal. A determination is made whether to request a forward link power adjustment. If the determination is that a forward link power adjustment is required, a request may be made into a radio access network (RAN) to adjust power. The RAN may select a subset of wireless coverage areas in which to adjust power. If further power adjustment is required, a further request may be made into the RAN, and the RAN may select a different subset of wireless coverage areas in which to adjust power.

摘要： A method and system is disclosed for dynamic adjustment of auxiliary pilot triggering based on latency. In an example embodiment, an AT that engages in a data communication that requires low latency will transmit its auxiliary pilot unconditionally and without regard to the payload sizes of the packets it transmits. Thus, the AT will not use a comparison of payload packet size with a threshold packet size when determining whether to transmit its auxiliary pilot. Rather, the AT will begin transmitting its auxiliary pilot upon a determination that it is engaged or will engage or has begun to engage in a communication that requires low latency. At the same time, an AT that engages in data communication that does not require low latency will advantageously trigger its auxiliary pilot less aggressively in response to an instruction from the base station to do so.

摘要： A method and system is disclosed for intelligent power control in a wireless communication system. In accordance with an example embodiment, a first device will operate in a dynamic-power state in which it transmits a power-increment command or power-decrement command in response to each of periodic comparisons of a signal power level of a signal received from a second device with a threshold power level. While operating in the dynamic-power state, the first device will recognize when it has transmitted a threshold number of alternating power-increment and power-decrement commands, and responsively will transition to operating in a steady-power state in which it continues to transmit alternating power-increment and power-decrement commands even if it detects that the second device has ceased responding to the alternating power-increment and power-decrement commands. While operating in the steady-power state, the first device will recognize when the difference between a currently-received signal power level and the threshold power level is greater than a differential threshold power, and based at least on the recognition will transition to operating in the dynamic power state.

摘要： A method and system is disclosed for variable persistence delay in access terminals receiving a concatenate page message. When an access terminal (e.g., a mobile station or wireless communication device) receives a page message that it determines is part of a concatenated page message, the access terminal will compute a backoff delay and a persistence delay according to delay parameters selected based upon the determination. According to an example embodiment, the access terminal will use the place-order of the received page record in the concatenation of page records in the page message to select values of the delay parameters. Other access terminals receiving the same concatenated page message will similarly select delay parameters. By associating the delay parameter values with place-order in the concatenated page message, each access terminal may used different values, and thereby compute different delays.

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 for vertical handoff of a mobile station from a first-protocol RAN to a second-protocol RAN. The method and system provide a make-before-break vertical handoff, by having the first-protocol RAN (i) acquire, on behalf of the mobile station, a traffic channel assignment defining one or more traffic channel parameters for air interface communication in the second-protocol RAN, and (ii) pass to the mobile station, via the first air interface protocol, the one or more traffic channel parameters so that the mobile station can then readily switch over to communication under the second-protocol RAN. Optimally, the acquisition and passing of the one or more second-protocol traffic channel parameters may occur without the mobile station having requested the handoff, without the mobile station having asked for the traffic channel assignment, and without the mobile station having yet begun communication with the second-protocol RAN.

摘要： A method and system is disclosed for setting forward-link power for an access terminal operating in a coverage area of a wireless communication system, whereby power is redistributed from access terminals operating in the same coverage area and having forward-link power in excess of their needs for maintaining acceptable service quality, to an access terminal that is in need of additional forward-link power in order to attain a desired or required level of service quality. Following a determination that a given access terminal is requesting a forward-link transmission power level that exceeds a first threshold power level, a number of other access terminals are identified as each having requested a respective decrease in forward-link transmission power level by an amount at least as large as a respective threshold amount. Forward link power to the given access terminal is then increased by an incremental amount, and the forward-link transmission power level to each of the number of other access terminals is decreased by a respective decremental amount, wherein the sum of all the respective decremental amounts equals at least the incremental amount.

摘要： A wireless network is used for a communication session between a mobile station and an endpoint. The wireless network receives endpoint bits representing communications from the endpoint for the mobile station and uses a first sector to transmit a forward link signal that encodes the endpoint hits. The mobile station generates mobile station hits representing communications from the mobile station for the endpoint and transmits a reverse link signal encoding the mobile station bits. A controller detects an imbalance between an error level in the forward link signal received by the mobile station and an error level in the reverse link signal received by the first sector. In response, the wireless network uses a second sector to receive the reverse link signal without using the second sector to transmit the endpoint bits. The reverse link signals received by the first and second sectors may be combined for diversity gain.
