Abstract: A user equipment (UE) reduces call drop during a measurement procedures. In one instance the UE determines whether a connected mode discontinuous reception (C-DRX) off period in a C-DRX cycle is longer than a synchronization channel repetition period of a neighbor radio access technology (RAT). The UE then performs inter RAT measurement when the C-DRX off period in the C-DRX cycle is longer and a serving cell signal quality is below the UE determined threshold. The UE sleeps when the C-DRX off period is shorter or the serving cell signal quality is above the UE determined threshold.

Abstract translation: 用户设备（UE）在测量过程中减少呼叫丢弃。 在一个实例中，UE确定C-DRX周期中连接的模式不连续接收（C-DRX）关闭周期是否长于相邻无线电接入技术（RAT）的同步信道重复周期。 然后，当C-DRX周期中的C-DRX关闭时段较长并且服务小区信号质量低于UE确定的阈值时，UE执行RAT间测量。 当C-DRX关闭时段较短或服务小区信号质量高于UE确定的阈值时，UE休眠。

Abstract: A user equipment (UE) reduces handover failure when the UE is prematurely handed over to a target cell during a single radio-voice call continuity (SRVCC) procedure or when the target cell is unavailable. In one instance, the UE prevents handover of a packet-switched (PS) voice call from a serving cell of a PS radio access technology (RAT) to the target cell of a circuit-switched (CS) RAT after the UE sends a measurement report for the target cell but before receiving a handover command. The UE prevents the handover if the target cell becomes undesirable for handover and/or the serving cell becomes desirable for maintaining the PS voice call.

Abstract translation: 当UE在单个无线电语音呼叫连续性（SRVCC）过程期间或当目标小区不可用时，UE在过早地切换到目标小区时，用户设备（UE）减少切换失败。 在一种情况下，UE在UE发送测量之后防止分组交换（PS）语音呼叫从PS无线电接入技术（RAT）的服务小区切换到电路交换（CS）RAT的目标小区 报告目标小区，但在接收到切换命令之前。 如果目标小区变得不希望用于切换，和/或服务小区变得期望用于维持PS语音呼叫，则UE防止切换。

Abstract: A measurement report may trigger a handover based on relative signal strengths of a serving cell and an intra/inter-RAT (radio access technology) neighbor cell. This may result in a UE being handed over to a weak cell and cause a voice call to drop. A method of wireless communication includes determining whether to delay sending an inter-RAT or an intra-RAT measurement report based in part on a current status of a call setup and whether the UE and a network support an inter-RAT handover while in the current status of the call setup. The measurement report is delayed for a predetermined time period based in part on the determination. The method also includes sending the measurement report when the predetermined time period expire and/or the current status of the call setup changes to a new status when both the UE and the network support the inter-RAT handover.

Abstract: A user equipment (UE) may reduce potential delay when attempting to return to a first radio access technology (RAT) after a circuit-switched fall back (CSFB) call releases at a second RAT. The UE may first determine its speed when the CSFB call releases. The UE then suspends a return to the first RAT without searching non-dedicated frequencies of the first RAT. This occurs when the UE speed is above a first predefined threshold and a signal quality of a dedicated frequency of the first RAT, included in a release message from a network of the second RAT or in a record of the UE, is below a second predetermined threshold. The UE may also search non-dedicated frequencies of the first RAT when the UE speed is below the first predefined threshold and the signal quality of the dedicated frequency of the first RAT is below the second predetermined threshold.

Abstract translation: 当在第二RAT处的电路交换回退（CSFB）呼叫释放之后尝试返回到第一无线电接入技术（RAT）时，用户设备（UE）可以减少潜在的延迟。 当CSFB呼叫释放时，UE可以首先确定其速度。 然后，UE暂停返回到第一RAT而不搜索第一RAT的非专用频率。 这发生在UE速度高于第一预定义阈值并且包括在来自第二RAT的网络的释放消息中或在UE的记录中的第一RAT的专用频率的信号质量低于第二预定阈值时 阈。 当UE速度低于第一预定阈值并且第一RAT的专用频率的信号质量低于第二预定阈值时，UE还可以搜索第一RAT的非专用频率。

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.
