Abstract: Certain aspects of the present disclosure provide techniques for user equipment (UE) initiated enhanced connected discontinuous reception (C-DRX) commands. An example method, performed at a user equipment (UE), generally includes receiving first signaling configuring the UE for an enhanced connected discontinuous reception (C-DRX) mode, and transmitting a request for the UE to enter a low power state during a current C-DRX cycle prior to expiration of at least one of an on duration timer or inactivity timer, wherein the request proposes the UE remain in the low power state for a first number of one or more future C-DRX cycles.

Abstract: A method for wireless communication performed by a user equipment (UE) includes transmitting, to a first network, a first message comprising a first measurement gap configuration, a measurement gap reconfiguration, a selection from a measurement gap pool, or a measurement gap release. The method also includes receiving a second message, from the first network. The second message may configure a measurement gap, reconfigure a measurement gap, or release a measurement gap. The second message may also suspend data communication from the UE during a configured measurement gap. The method additionally includes suspending communication with the first network during the configured measurement gap. The communication may be suspended to save power, tune away for a multiple subscriber identity module (MSIM) of the UE, or measure a neighbor cell.

Abstract: Aspects relate to methods and apparatus for dedicated bearer (DB) establishment handling during call setup for long term evolution. According to aspects, a method is provided herein for wireless communications that may be performed, for example, by a user equipment (UE). The method generally includes establishing a connection with a first access point (AP) to perform a call set up procedure for a call; receiving from the first AP a message associated with handover to a second AP; delaying giving up the call setup procedure for a duration if the message includes or is associated with an indication to release a dedicated bearer; and allowing establishment of a DB with the second AP during the duration. Consequently, the DB can be established with the second AP, without the UE giving up the call setup, and the call can be performed, thus improving user experience. Numerous other aspects are provided.

Abstract: A user equipment (UE) reduces delays associated with inter-radio access technology (IRAT) measurements. In one instance, the UE determines whether a first signal quality of a serving cell, a second signal quality of an intra frequency neighbor cell of a serving RAT (radio access technology), and/or a third signal quality of an inter frequency neighbor cell of the serving RAT is below a first threshold. The UE also determines whether a fourth signal quality of at least one cell of a neighbor RAT is above a second threshold. The UE further allocates one or more measurement gaps for a synchronization channel decoding procedure for the neighbor RAT based at least in part on the determining whether the fourth signal quality is above the second threshold and determining whether the first, second, and/or third signal quality is below the first threshold.

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: 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: 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 translation: 测量报告可以基于服务小区和帧内/ RAT间（无线接入技术）相邻小区的相对信号强度触发切换。 这可能导致UE被切换到弱小区并导致语音呼叫掉线。 一种无线通信方法包括：部分地基于呼叫建立的当前状态来确定是否延迟发送RAT间或RAT内测量报告，以及UE在当前和当前时刻是否支持RAT间切换 通话设置状态。 部分地基于确定，测量报告被延迟预定的时间段。 该方法还包括当UE和网络都支持RAT间切换时，当预定时间段到期时和/或呼叫建立的当前状态变为新状态，发送测量报告。

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。
