Abstract: Certain aspects of the present disclosure relate to methods and apparatus for sending fast negative acknowledgements (NACKs) after a user equipment (UE) tunes back to a first network after tuning away from the first network. The UE may determine that a trigger event has occurred, and in response to the determination, modify a NACK timing configuration from a default configuration. Modifying the NACK timing configuration may include using an aggressive NACK timing configuration for a configurable period of time, in response to detecting a trigger event. The trigger event may include detecting missed packets after a tune back, unavailability of sufficient memory to hold packets until a gap created by missed packets may be filled, or tuning back to a network.

Abstract translation: 本公开的某些方面涉及用于在从第一网络调谐之后用户设备（UE）回调到第一网络之后发送快速否定确认（NACK）的方法和装置。 UE可以确定已经发生触发事件，并且响应于该确定，从默认配置修改NACK定时配置。 修改NACK定时配置可以包括响应于检测到触发事件而在可配置的时间段内使用积极的NACK定时配置。 触发事件可以包括在回调之后检测错过的分组，不可用的足够的存储器来保存分组，直到由丢失的分组创建的间隙可能被填充或者回调到网络。

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE) or component thereof. The apparatus may be configured to transmit to a base station a first request to transmit data in a buffer. The apparatus may be further configured to transmit to the base station a second request to transmit the data in the buffer in absence of a grant in response to the first transmit request. The apparatus may be further configured to remain awake for at least a portion of a scheduled discontinuous reception (DRX) sleep state following the transmission of the second request.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor packet data convergence protocol (PDCP) counter values associated with PDCP packets. The UE may control a PDCP mode of the UE based at least in part on the monitoring of the PDCP counter values. Numerous other aspects are provided.

Abstract: Aspects described herein relate to wireless communications. Protocol data units (PDUs) can be received at a network layer from one or more transmitting nodes using a link associated with each respective transmitting node. One or more missing PDUs can be detected based, at least in part, on sequence numbers of the received PDUs. A timer can be started based on the detection of the one or more missing PDUs. In response to expiration of the timer, and without receiving the one or more missing PDUs before the expiration of the timer, a lower network layer can be notified that the one or more missing PDUs are received to prevent attempted transmitting/retransmitting or other processing of the one or more missing PDUs.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for quick radio link control (RLC) retransmission on hybrid automatic repeat request (HARQ) failure during tune away. According to certain aspects, a method for wireless communications is provided. The method generally includes performing communications with a base station (BS) using radio components tuned to a first air interface, detecting a tune-away of the radio components from the first air interface to a second air interface while performing the communications, and scheduling one or more packets for retransmission to the BS upon completion of the tune-away, wherein the one or more packets are one or more packets that failed to be transmitted due to the tune-away.

Abstract: Aspects of the present disclosure provide methods, systems, devices and/or apparatuses for logical channel prioritization by a user equipment (UE) within a Long Term Evolution (LTE) wireless communications network. The UE may have multiple logical channels each associated with one or more applications or services of the UE. The UE may identify whether a quality of service (QoS) obligation to allocate at least a portion of uplink resources to a logical channel for a time period is present, and may also identify whether the logical channel has control data to be transmitted from the UE. If a QoS obligation and/or control data are present for the logical channel, the UE may allocate at least a portion of the uplink resources to the logical channel.

Abstract translation: 本公开的方面提供了用于在长期演进（LTE）无线通信网络内的用户设备（UE）进行逻辑信道优先化的方法，系统，设备和/或设备。 UE可以具有与UE的一个或多个应用或服务相关联的多个逻辑信道。 UE可以识别在一段时间内是否存在向逻辑信道分配上行链路资源的至少一部分的服务质量（QoS）义务，并且还可以识别逻辑信道是否具有要从UE发送的控制数据 。 如果对于逻辑信道存在QoS义务和/或控制数据，则UE可以将至少一部分上行链路资源分配给逻辑信道。
