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.

Abstract: A process includes receiving a first communication on a first call associated with a first subscriber identity module (SIM) in an user equipment (UE). The process further includes receiving a second communications on a second call associated with a second SIM in the UE. The process also includes outputting from the UE the received first communications and the received second communications. The process further includes selectively transmitting communications from the UE to an active call selected from one of the first call or the second call.

Abstract: A system acquisition is initiated to perform inter radio access technology (IRAT) measurement. A waiting period of time is provided before aborting the system acquisition. The period of time is adjustable based on at least one metric. The metric can be a frequency of available measurement gaps, a total number of available measurement gaps, and/or a length of each measurement gap within a subframe. The metric could also be an absolute signal strength of a single neighbor cell and/or a relative signal strength between neighbor cells. The metric could also be a user equipment (UE) measured signal strength compared to a network indicated threshold value for triggering an IRAT measurement report. The metric could also be a percentage of a tone that falls within a measurement gap.

Abstract: A method, an apparatus, and a computer program product for wireless communication at a fourth generation (4G) capable user equipment (UE) include determining, when the 4G capable UE does not report a 4G capability but reports one or more other radio access technology (RAT) capabilities, a 4G service change possibility for the 4G capable UE, performing a 4G network search and measurement procedure in response to the determination of the 4G service change possibility, and performing a combined evolved packet system/circuit switched (EPS/CS) attach attempt procedure when the 4G network search and measurement procedure indicates a 4G network availability.

Abstract: A UE is configured to collect multiple absolute radio frequency channel numbers (ARFCNs) in parallel via a wideband receiver during a transmission gap. Inter-radio access technology (IRAT) measurements are performed based on the collected AFRCN samples.

Abstract: A method of wireless communication measures a signal strength and/or quality of a target cell. An absolute threshold value is set based at least in part on the rank difference between a serving cell and the target cell. The serving cell and target cell may have the same priority or no network indicated priority. The UE reselects to the target cell when the signal strength exceeds the absolute threshold value.

Abstract: In a system and method for wireless communication, a user equipment (UE) is configured to determine whether it failed to detect and decode a data transmission while the UE tuned away from a first RAT to a second RAT based on a grant sequence number. The HARQ buffer is flushed when the UE determines it missed a grant and the duration of the tune away gap meets a particular criteria.

Abstract: A user equipment (UE) determines which neighbor cell frequencies and radio access technologies (RATs) to measure based on the UE's recorded history of measurement results and searches. In one instance, the UE determines a set of neighbor cells for each of multiple serving cells. The UE records measurement results and search history for each of the set of neighbor cells, and the corresponding multiple serving cells. In another instance, the UE determines a measurement schedule for neighbor cells, including neighbor RATs and/or frequencies, based on the recorded measurement results, search history and the current serving cell.

Abstract: Methods and apparatuses relating to wireless communication of a user equipment (UE) are provided including receiving an indication to perform a call origination procedure when communicating in a serving cell, selecting a neighbor cell for performing the call origination procedure based at least in part on receiving the indication and performing the call origination procedure with a wireless network using the neighbor cell after selecting the neighbor cell in response to receiving the indication. Selecting the neighbor cell can include performing reselection or switching subscriptions in a multiple subscription UE while delaying the call origination procedure until after the selection.

Abstract: A user equipment (UE) transmits measurement reports, and postpones the transmission of a measurement report when a neighbor cell signal strength is greater than the signal strength of the target cell(s). In one instance, the UE identifies a target cell having the strongest signal strength. In another instance, the UE postpones a transmission of a measurement report for a target cell when a neighbor cell signal strength is greater than the strongest target cell signal strength and the strongest target cell signal strength is below an absolute threshold value.

Abstract: A user equipment (UE) determines an uplink timing advance of a target NodeB, such as an uplink dedicated physical channel (DPCH) transmit timing, during handover transition when the UE receives a handover command without a random access configuration. In one instance, the UE modifies a current timing advance of a source eNodeB based on a difference between an uplink timing of the source eNodeB and a downlink timing of the source eNodeB and a difference between an uplink timing of the target NodeB and a downlink timing of the target NodeB. In another instance, the UE determines the uplink timing advance of the target NodeB based on the modified current uplink timing advance of the source eNodeB.

Abstract: In an aspect of the disclosure, a method of wireless communication is provided. The method may include starting a first timer for changing to a first network cell with a first radio access technology (RAT) and starting a second timer for changing to a second network cell with a second RAT. Further, the method may include changing to the first network cell when the first timer expires. The method may also include determining that the second network cell satisfies a cell change condition and continuing to run the second timer after the change to the first network cell in response to the second network cell satisfying the cell change condition. The method may further include changing to the second network cell after starting a third timer for a third network cell with the first RAT, a duration of the second timer being longer than a duration of the third timer.

Abstract: A user equipment (UE) reselects to a higher priority cell even when a cell reselection timer of a low priority cell and/or rank based cell expires before a cell reselection timer of the higher priority cell. In one instance, the UE determines an expiration of a first cell reselection timer for the low priority cell and/or an expiration of a second cell reselection timer for the rank based cell while a third cell reselection timer is running, but not expired. The third cell reselection timer corresponds to the high priority based cell. The UE delays performing cell reselection to the low priority or rank based cell until the high priority based cell is evaluated, even when a cell reselection condition has been stratified for the low priority or rank based cell.

Abstract: A method of wireless communication is presented. The method includes receiving a grant insufficient for all hybrid automatic repeat request (HARQ) processes waiting for retransmission. The grant may be received after a measurement gap. The method also includes discarding one or more HARQ processes having a timing of previous ACK/NACK feedback coinciding with the measurement gap.

Abstract: A method and apparatus for wireless communication comprising switching an uplink (UL) from a source cell to a target cell; and receiving a Synchronization Shift (SS) command from the source cell, wherein the SS command is generated by the target cell. In one aspect, the method and apparatus further comprise switching a downlink (DL) through the target cell; completing a physical channel reconfiguration; and sending a Physical Channel Reconfiguration Complete message to the Radio Network Controller (RNC) through the target cell.

Abstract: Methods and apparatus are provided for selecting identifying numbers associated with a mobile station (MS) having multiple subscriber identity modules (SIMs) such that the paging intervals for both identifying numbers are aligned. The MS having multiple SIMs may operate in a network via a particular radio access technology (RAT), such as Wideband Code Division Multiple Access (W-CDMA). By having aligned paging intervals, the MS may wake up only once during the paging cycles for the various identifying numbers rather than waking up multiple times, thereby reducing power consumption of the MS during idle mode compared to a conventional MS with multiple SIMs, and thus multiple identifying numbers.

Abstract: A user equipment (UE) may perform an inter radio access technology (IRAT) measurement in time slots not deemed to be carrying critical data. In such instances, the UE only transmits and decodes critical data in the critical time slots when a serving cell signal is low for a determined period of time. Otherwise, when the time slots do not carry critical data, i.e., non-critical time slots, the UE stops transmitting and decoding and uses the non-critical time slots for IRAT measurement.

Abstract: Described herein are aspects related to communicating with a first radio access technology (RAT) and a second RAT, wherein a set of multi-input, multi-output (MIMO) resources is allocated for communication between a mobile station (MS) and a base station (BS) of the first RAT. A request message is sent to the BS of the first RAT requesting reallocation of at least a portion of the set of MIMO resources in a scan duration. During the scan duration, signals are received from a BS of the second RAT over a reallocated subset of the set of MIMO resources and communications occur with the BS of the first RAT over a non-reallocated subset of the set of MIMO resources. During a normal duration subsequent to the scan duration, communications occur with the BS of the first RAT using the set of MIMO resources including at least some of the reallocated subset of the set of MIMO resources.

Abstract: A user equipment (UE) performs hard handover rather than baton handover when a handover command includes a scheduling request configuration and includes no random access configuration. When the UE receives a handover command including a scheduling request configuration, and no random access configuration, the UE determines the random access configuration for the hard handover based on the scheduling request configuration.

Abstract: A method of wireless communication adjusts the transmit power for high speed data communications. A UE determines whether a random access channel is configured on an uplink traffic time slot. When the random access channel is configured on the uplink traffic time slot, the UE transmits a high speed data channel with adjusted transmit (TX) power based at least in part on transmit power used for a scheduling request.
