Abstract:
A user equipment (UE) is configured to adaptively switch between different techniques/methods for performing inter-frequency or inter-radio access technology measurement. The UE may use one technique for measurement based on certain communication conditions and in response to a change in communication conditions may switch to another measurement technique. Different techniques may be used such as using a network configured communication gap, using a connected discontinuous reception cycle off-period for measurement, or other techniques.
Abstract:
A user equipment (UE) periodically suspends communications on a first radio access technology (RAT) to redirect another communication or initiate the other communication on a second RAT. In one instance, the UE suspends an application running on the first RAT before switching to the second RAT. Prior to returning from the second RAT to the first RAT, the UE ranks frequencies of the first RAT in an acquisition history based on a type of a suspended application in the first RAT, and characteristics of each frequency in the acquisition history. The UE then search one or more frequencies in the acquisition history in accordance with the ranking.
Abstract:
A user equipment (UE) reduces redirection failure resulting from failed paging responses and/or location area updates when a user equipment is redirected from a first radio access technology (RAT) to a second RAT in accordance with a mobile terminated (MT) call. The UE is redirected from a first RAT to a second RAT in response to receiving a page for a call. The UE searches for neighbor cells of a first cell when a first paging response failed for the first cell in the second RAT. The UE also attempts to acquire a neighbor cell. The UE sends a second paging response, with a redirection indicator, to either the first cell or the neighbor cell based on a signal quality of the first cell and a signal quality of the neighbor cell when a failure of the first paging response to the first cell occurred within a predetermined time period.
Abstract:
A multi-subscriber identity module (SIM) user equipment (UE) reduces call interruptions caused by tuning away. In one instance, the user equipment determines whether to abort a tune away procedure to a second subscriber identity module at the user equipment. The determination is based on a type of procedure running on a first subscriber identity module at the user equipment and/or a characteristic of an intended tune away to the second subscriber identity module.
Abstract:
A user equipment (UE) improves measurement procedures, such as signal quality measurements and base station identity code (BSIC) procedures. In one instance, the UE determines signal qualities of a serving cell and neighbor cells of a serving RAT (radio access technology). The UE the adjusts a C-DRX off duration connected discontinuous reception off duration) on a component carrier to perform measurements of a non-serving RAT during the C-DRX off duration based on the determined signal qualities of the serving RAT.
Abstract:
A method and apparatus for wireless communication avoids handover to a non-best neighbor cell. While in a connected mode of operation, a user equipment (UE) determines whether a neighbor cell is the best cell. When the neighbor cell is not the best cell and a time to trigger (TTT) associated with the neighbor cell expires, the UE delays reporting the non-best neighbor cell to a network.
Abstract:
A method and/or apparatus for wireless communication in a multi-SIM user equipment includes receiving a list of neighboring base stations from a serving base station of a first SIM. The serving base station of a second SIM is identified and a final target base station is determined for a cell reselection procedure and/or cell change order procedure from among the neighboring base stations and the serving base station of the second SIM.
Abstract:
A method of wireless communication includes receiving a first grant and first high speed downlink data before tuning away from a first RAT and storing the first high speed data in a buffer corresponding to a first HARQ ID indicated in the first grant after failing to decode the first high speed downlink data. The method also includes receiving a second grant and second high speed data after tuning back to the first RAT after tuning away to a second RAT. The method further includes determining whether the second high speed data is a new transmission or a retransmission of the first high speed data without processing a new data indicator.
Abstract:
A user equipment (UE) expedites cell reselection from a higher priority radio access technology (RAT) to a lower priority RAT. In one instance, the UE determines whether a serving cell signal quality exceeds a threshold when a UE is in idle mode. The serving cell is associated with a higher priority RAT. In another instance, the UE performs an expedited search and measurement of cells of a lower priority RAT when the serving cell signal quality is below the threshold by commencing search and measurement before a next discontinuous reception (DRX) cycle scheduled for measurement.
Abstract:
An apparatus and method for wireless communication extends a measurement gap in a high speed data network. When it is determined a high speed data channel will fall within a measurement gap, the monitoring of the grant channel corresponding to the high speed data channel is skipped. The measurement gap is extended for inter radio access technology (IRAT) measurement to include the time slot containing the grant channel when the time slot only includes the grant channel corresponding to the high speed data channel that will fall in the measurement gap.
