    摘要: A communication transceiver transmits a power-controlled first signal responsive to received power control commands and transmits one or more additional signals at variable power gains relative to the transmit power of the first signal based on reception quality feedback received for the additional signals. Thus, a mobile station may transmit a traffic channel at a variable power gain relative to its pilot signal power and vary that gain responsive to reception quality feedback received by it for the traffic signal. Of course, the mobile station may float more than one traffic channel using variable gains and may use different variable gains for each one. Further, the mobile station may float one or more non-pilot channels relative to the pilot or relative to another channel, while transmitting one or more fixed gain channels. Similar variable power gain may be employed at network base stations for forward link signals.

    摘要: Systems and methodologies are described that facilitate providing neighbor lists to devices comprising pilot frequencies of access points in a specific geographic region. Using the neighbor list, the devices can discover the access points based on scanning the frequencies for the pilot and can determine additional communication parameters from the discovery or based on a subsequent request resulting from discovery. In this regard, access point information need not be provisioned to the devices for locating the access points, selecting/reselecting the access points, providing the access points in a list to an interface, locating the device using triangulation based on GPS position of the access points, and/or the like.

    摘要: A wireless communication network receives packet data transmissions from a mobile station, tracks the occurrence of retransmission requests sent to the mobile station responsive thereto, and modifies the radio link assignments for the mobile station based at least in part on said tracking. For example, a base station controller may be configured to manage the active set of a mobile station based on the number and/or frequency of NACK messages sent by the radio base stations in the mobile station's active set(s) responsive to packet data transmissions from the mobile station. The ACK/NACK response of a radio base station to mobile station transmissions may be used to detect link imbalance, identify poor reverse link channels, etc. The base station controller can add or change radio links based on the ACK/NACK response to improve reverse link performance, trigger voice call handoff, correct link imbalance, etc.

    摘要: A method of reverse link power control for a reverse packet data channel in a wireless communication system allows a mobile station to autonomously change its data transmission rate. The mobile station transmits packet data over a reverse packet data channel having a data rate variant transmit power level that varies based on a transmit data rate on the packet data channel. The mobile station further transmits control signals over a reverse control channel associated with the reverse packet data channel. The transmit power level of the reverse control channel is such that the transmit power level does not vary with the transmit data rate on the packet data channel. The radio base station measures the strength of the received signals on the reverse control channel, compares the measured strength to a power control set point, and generates a power control signal responsive to the comparison of the control signal to the power control set point.

    摘要: A code division multiple access (CDMA) communications system comprises a plurality of CDMA transmitters and at least one reception station coupled together by a communications channel. Each CDMA transmitter encodes a digital signal with a spreading code, each bit of the digital signal being encoded by a spreading code segment comprising a multiplicity of chips. All of the transmitters transmit their respective encoded signals to the reception station asynchronously via the communications channel so as to occupy the same bandwidth. Each receiver receives the combined signals of all of the transmitters and correlates it with a selected one of the spreading code segments to detect the digital signal from the corresponding transmitter. Each receiver uses also the signal-to-noise ratios of detected signals other than its own, with respect to chip delays relative to a reference one of the signals, to suppress multiple access interference (MAI) caused by such other detected signals.

    摘要: Systems, apparatus and methods for facilitating identification and/or acquisition of an access point are provided. Methods can include transmitting or receiving access point information (“API”) indicative of an identification of the access point (“AP”). The API can be provided at the AP through hardwiring or receipt of configuration information input by a user or transmitted to the AP by a network operator through Over-The-Air (“OTA”) signaling. The API can be computer-readable and, in some embodiments, the API can also be human-readable. The API can be transmitted on a paging channel from which user equipment (“UE”) can receive information. The frequency at which the API is transmitted can be fixed, dynamic and/or configurable. Upon receipt of the API, acquisition of the AP is attempted if the AP is determined to be a permitted AP.

    摘要: Systems and methodologies are described that facilitate identifying and/or selecting femto cells in a wireless communication environment. A mobile device can scan an Auxiliary Pilot Channel to detect auxiliary pilot channel information (e.g., a particular Walsh Code, . . . ) sent from a base station. Moreover, the identified auxiliary pilot channel information can be evaluated to detect a characteristic of the base station. For instance, the identified auxiliary pilot channel information can be compared with stored auxiliary pilot channel information (e.g., Walsh Code(s) included in a whitelist, blacklist, . . . ). Moreover, a Synchronization Channel can be read based upon the detected characteristic. Further, a Common Pilot Channel, for example, can be analyzed to search for pseudo-noise (PN) offset(s) reserved for femto cell base stations, and the scan of the Auxiliary Pilot Channel can be initiated in response to detecting at least one reserved PN offset.
