Abstract: A method and apparatus for wireless communication adjusts thresholds for performing IRAT neighbor measurements and inter-frequency neighbor measurements. A serving cell search threshold for determining when to perform IRAT neighbor measurements is scaled and a serving cell search threshold for determining when to perform inter-frequency neighbor cell measurements is maintained. Inter-frequency neighbor measurements are performed when a serving cell signal quality is below the maintained, non-scaled, serving cell search threshold and IRAT neighbor measurements are performed when the serving cell signal quality is below the scaled serving cell search threshold.

Abstract: A user equipment (UE) camped on a first RAT and in a coverage area of a second RAT searches for one or more frequencies of the second RAT and measures one or more detected cells corresponding to the one or more frequencies of the second RAT. When the measurement indicates that cell reselection/handover trigger conditions are met the UE starts a cell reselection timer or time to trigger. The UE schedules a measurement of the neighbor cell during a time instance close to when the reselection timer or time to trigger expires.

Abstract: A method for cell reselection includes camping on a first cell in response to detecting the first cell during a first background search. The method also includes recording an IRAT cell reselection serving cell threshold and reselecting a second cell of a second RAT when the first cell of the first RAT is below the threshold and the second cell of the second RAT is above a threshold. The method further includes detecting a second cell of the first RAT in response to performing a second background search and comparing a signal quality of the second cell with a sum of the recorded threshold and a predefined threshold value. The method still further includes on the second cell when the signal quality of the second cell exceeds the threshold plus a predefined threshold.

Abstract: In a method of wireless communication, a grant allocating a plurality of high speed subframes for high speed data channels is received before a measurement gap for tuning away from a serving radio access technology (RAT). At least one high speed subframe is allocated in the grant falling within the measurement gap. High speed data is processed only on high speed subframes of the plurality of high speed subframes before and after the measurement gap. An acknowledgement/negative acknowledgement (ACK/NACK) feedback is transmitting and only the high speed subframes of the plurality of high speed subframes before and after the measurement gap are considered.

Abstract: A method and apparatus for improved downlink data transport with hybrid automatic repeat request (HARQ) feedback and a measurement gap are provided. A user equipment (UE) receives from a network a transmission grant for downlink data on a first control channel. The UE receives the data from the network via a transport channel. In response to the received data, the UE determines whether transmission of an acknowledgement message falls in a measurement gap. Upon determining that the transmission of the acknowledgement message by the UE falls in the measurement gap, and prior to receiving from the network a retransmission grant for the data on the first control channel, the UE sends the acknowledgement message on a second control channel in a sub-frame following the measurement gap. The first control channel is associated with the second control channel.

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: 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 may improve throughput between the user equipment and a nodeB by reducing a delay associated with transmitting new scheduling information. In some instances, when scheduling information changes during or prior to the retransmission of the previous scheduling information, the user equipment aborts a retransmission of the previous scheduling information and initiates a new scheduling information transmission using a scheduling grant received at the time of aborting or after the time of aborting.
