  • Patent number: 9084151
    Abstract: Wireless communication in a multicarrier radio access network may be implemented where a user equipment (UE) maintains communication with various carrier frequencies in the multicarrier network. The UE will receive an indication from a node B to measure a signal quality on one of a number of carrier frequencies in the network. The UE will then measure the signal quality on the carrier frequency based on measurements using a downlink synchronization code transmitted by the node B on the downlink pilot channel of the carrier frequencies in the multicarrier network. The UE may then report the channel quality back to the node B.

  • Patent number: 9084126
    Abstract: Methods and apparatuses are presented for determining a location of a mobile station. In some embodiments, a mobile station may acquire at least one attribute of a reference base station to obtain the identity of the reference base station. A first and a second locally unique attribute of a local base station may then be acquired. The mobile station may then compute a distance metric from the mobile station to the reference base station based on the at least one attribute, and the first and second locally unique attributes. The location of the mobile station may be determined based at least in part on the distance metric. In some embodiments, the distance metric may include a number of how many base stations away (i.e. “hops” or number of handovers) the mobile station is from the reference base station.

  • Patent number: 9084184
    Abstract: In a wireless communication system, a user equipment (UE) may be capable of communication on multiple radio access networks. A UE may be in simultaneous communication with one radio access network, such as TD-SCDMA for circuit-switched voice calls and with another radio access network, such as TDD-LTE for packet-switched data communications. When the TDD-LTE network is idle, the UE may evaluate signal strength of the respective network for potential cell reselection. The UE may measure only a serving TD-SCDMA cell for purposes of switching packet-switched service to the TD-SCDMA network, thereby avoiding a situation where the UE attempts to connect to a different TD-SCDMA cell for purposes of packet-switched communications than the cell presently affiliated with the UE for circuit-switched communications.
