Abstract: Various techniques are disclosed for unambiguously determining and tracking frame offset in asynchronous wireless communication user equipment. The user equipment determines the unambiguous connection frame number of a downlink channel. The equipment then determines frame timing information for neighbor cells. The frame timing information for the primary common control physical channel and uplink dedicated physical channels is determined. The frame timing is determined as a coarse resolution frame offset in conjunction with a fine resolution chip offset. The frame numbering information for the uplink and downlink dedicated physical channels and the primary common control physical channel is also determined. Then the frame number and timing information is updated using a counter accurate to one chip resolution. The frame offset is updated if the number of chips underflows or overflows a predetermined window. Frame timing may be updated by updating only the fine chip offset or may be completely determined.

Abstract: A method and apparatus for providing a mobile station user (8) with information about anticipated roaming charges. The visitor communication system (7) transmits a graded roaming signal to the mobile station user (8) indicative of the anticipated roaming costs. The graded roaming signal is determined by contractual agreements between the visitor communication system provider and user's service provider. This information is stored in a database at the user's home communication system (2) and is provided to the visitor communication system (7) upon request for authorization to provide service. The graded roaming signal is broadcast to the mobile station (8) and displayed to allow the mobile station user to estimate the cost of the service being provided.

Abstract: A rake receiver finger assignor is configured to assign a rake receiver finger to a time offset between identified signal path time offsets in accordance with a concentration of identified signal paths from a transmitter to a rake receiver. In accordance with the exemplary embodiment, a number of identified signal paths having time offsets within a time window are observed to determine the concentration of signal paths identified by a path searcher. If the number of identified signal paths indicates a concentrated distribution of signal paths such as during a fat path condition, at least one rake finger is assigned between at a time offset between two identified signal paths.

Abstract: Methods, systems and devices are provided for controlling a communication device. Embodiments include receiving, through the transceiver, a voice call from a first network subscription associated with a first SIM of the communication device. The voice call may interrupt an active data services session through the transceiver with a second network subscription associated with a second SIM of the communication device. Also, embodiments include establishing an active voice communication connection for the voice call on the transceiver with the first network subscription. Additionally, reestablishing the active data services session through the transceiver with the first network subscription while maintaining the active voice communication connection for the voice call with the first network subscription.

Abstract: Various embodiments include methods, systems, and devices for tuning away a mobile device's receiver without retuning the mobile device's transmitter, thereby allowing the mobile device to monitor multiple networks with a single radio frequency (RF) chain while avoiding the problems often associated with tune-away methods, such as loss of throughput, loss of tracking or synchronization, delays in acknowledgments, delays in rate control or channel quality control feedback, etc. The transmitter may remain tuned to a first network while the receiver may be separately tuned to one or more other networks. In various embodiments, the separately tuned receiver may monitor for paging signals on one or more networks while the transmitter remains tuned to the first network and transmits data or control signals.

Abstract: Techniques for operating a diversity receiver are described. A user equipment (UE) may include (i) a first receive chain having an equalizer and a first rake receiver and (ii) a second receive chain having a second rake receiver. The UE may support (i) a first mode in which only the equalizer is used to process a received transmission and (ii) a second mode in which both rake receivers are used to process the received transmission. The UE may determine a first performance metric for the first mode (e.g., based on the performance of the equalizer) and a second performance metric for the second mode (e.g., based on the performance of both rake receivers or only the first rake receiver). The UE may select the first or second mode based on the performance metrics and may power down the second receive chain if the first mode is selected.
