  • Patent number: 9467950
    Abstract: A system is implemented on a wireless network for adjusting a forward link power control parameter based on forward link feedback. A wireless unit is in communication with several base stations during soft handoff, and provides feedback relating to forward link quality, e.g., forward link pilot signal strength or traffic channel frame error rate. The feedback is compared to a comparison or reference point (such as target frame error rate, or a maximum pilot signal strength in the active set) chosen for gauging the quality or nature of the feedback for power control purposes. Based on this comparison, a power control parameter of one or more of the base stations may be adjusted upwards or downward. The power control parameter may be a forward link reference transmit power level “Pref” used to control base station power transmission levels in the presence of power control bit errors.

  • Patent number: 8335503
    Abstract: In an idle state transition from a macro mobile network to a femtocell, a mobile station looks for the femtocell to operate in a frequency band typically assigned to a macro network. For normal macro network operations, mobile stations look for base stations operating on various channels, e.g. based on hashing of respective mobile station identifiers. Femtocells generate a pilot beacon on a carrier frequency to enable mobile station acquisition, e.g. to redirect a mobile station to the operating frequency of the femtocell. To avoid the need to continually cycle or hop through all possible macro assigned carrier frequencies, pilot beacon transmissions of a particular femtocell are prioritized to correspond to the mobile station(s) expected to utilize that femtocell, e.g. by using existing network information, provisioning device information or self learning/calculating information regarding the carrier most likely to be used by any particular mobile station expected to use the femtocell.

  • Publication number: 20080076436
    Abstract: A method of call setup in a wireless communication system in which cross carrier Y traffic channels at a serving base station and one or more neighbor base stations are assigned to a mobile station during system access to improve call setup when the mobile station is in a cross carrier Y cell or coverage area of one of the neighbor base stations. The serving base station is selected by the mobile station based on the signal quality of an access carrier X. Traffic channels are assigned to the mobile station on the cross carrier Y at the serving base station and one or more neighbor base stations. If the cross carrier Y cell of the serving base station covers less geographical area than a corresponding access carrier X cell, then the mobile station may be in the cross carrier Y cell of one of the neighbor base stations.

  • Patent number: 7006485
    Abstract: A method for reducing multiple dominant pilots in a CDMA transmission system comprises linking a transceiver element with a nearby base station for transporting signals between the transceiver element and the nearby base station. Transmitting from the transceiver element forward link signals of a nearby sector associated with the nearby base station. An apparatus is also described.

  • Patent number: 6374103
    Abstract: A method and apparatus for arranging transmission of overhead messages on the paging channel of a wireless communications system is described. Certain paging channel slots are established, based on a timing reference, that must contain an overhead message. In the intervening slots or slot fragments, the base station transmits mobile-directed messages, when they are available. When no mobile directed messages are available for transmission, the base station selects an overhead message from a queue for transmission on the intervening paging channel slot or slot fragment.
