  • Patent number: 9060317
    Abstract: A method, computer readable medium and mobile device for operating using more than one Radio Access Technology (RAT) are provided. When the mobile device is operating in a serving cell of a first RAT, it obtains, through at least one of wireless access radios in the mobile device, a first set of candidate information from a message transmitted for the serving cell. It also obtains, through at least one of the wireless access radios, a second set of candidate information from a message transmitted for a neighbor cell of the serving cell. The mobile device considers the candidate information from the first set and the candidate information from the second set for reselection by the mobile device.

  • Patent number: 8582522
    Abstract: Systems, apparatus and methods can be implemented for handling physical uplink shared channel (PUSCH) transmissions. A user equipment (UE) can decode, on a physical hybrid automatic repeat request (HARQ) indicator channel (PHICH), a negative acknowledgement (NACK) associated with an HARQ process. The UE can also receive, from a base station, an uplink grant without an associated transport block. The decoded NACK and the received uplink grant can trigger a respective transmission during a PUSCH transmission opportunity. The UE can then perform, during the PUSCH transmission opportunity, one of transmission of a PUSCH transmission associated with the HARQ process, transmission of control information based on the received uplink grant, or disregarding the decoded NACK and the received uplink grant.

  • Patent number: 8554206
    Abstract: A handheld electronic device adapted to display a listing of known networks, scan for available networks, display a listing of the available networks and enable the entry of information relating to manually entered networks. In addition, the device is adapted to (1) enable the addition of preferred networks to a preferred network list wherein the preferred networks are one or more of: (i) certain of the known networks selected from the listing of known networks, (ii) certain of the available networks selected from the listing of available networks, and (iii) the manually entered networks; (2) enable the assignment of a priority value to each of the preferred networks; and (3) utilize the preferred networks for performing wireless communications when the device is in a roaming situation, wherein the preferred networks are utilized in a priority order that is based on the priority value assigned to each of the preferred networks.
