Abstract: Aspects generally relate to wireless communications and, more particularly, to methods, systems and apparatus for timing synchronization during a wireless uplink random access procedure. For example, certain aspects relate to a technique for receiving first timing advance information associated with uplink wireless communications with a base station (BS), transmitting a random access connection request message to the BS, receiving a random access response from the BS while the first timing advance information is within a valid time period, the random access response comprising second timing advance information associated with uplink wireless communications with the base station, determining, after receiving the random access response, that the valid time period for the first timing advance information has expired, and utilizing the second timing advance information for uplink communications with the BS after determining that the valid time period for the first timing advance information has expired. Numerous other aspects are provided.

Abstract: Various embodiments implemented on a mobile communication device (e.g., a multi-SIM-multi-active communication device) mitigate degraded transmit performance typically experienced by a lower-priority subscription during a Tx collision event in which a higher-priority subscription receives a shared Tx resource of the mobile communication device to the exclusion of the lower-priority subscription. Specifically, in various embodiments, a processor of the mobile communication device may determine when an upcoming transmission of the lower-priority subscription will collide with a scheduled transmission of the higher-priority subscription (i.e., may determine when a Tx collision event will occur between the subscriptions) and may implement one or more Tx collision management strategies in response to determining that the lower-priority subscription's upcoming transmission will collide with a transmission of the higher-priority subscription, thus improving the lower-priority subscription's overall performance.

Abstract: Systems and methods are described for scheduling transmission for a first radio access technology (RAT) and a second RAT including, but not limited to, determining likelihood of successful transmission for each of a plurality of frames associated with the second RAT based on an activity pattern associated with the first RAT. Transmission cost associated with each of a plurality of data blocks is determined. Each of the plurality of data blocks is transmittable via the second RAT. A first data block of the plurality of data blocks is assigned to a frame of the plurality of frames based, at least in part, on the likelihood of successful transmission associated with the frame and the transmission cost associated with the first data block (the data with highest priority/delay sensitivity is assigned to the subframe with highest likelihood of success).

Abstract: Methods, systems, and devices are described for improving discontinuous reception (DRX) periods using enhanced physical HARQ indicator channel (PHICH) decoding. A user equipment (UE) may determine that an uplink (UL) retransmission (ReTx) is unnecessary based on the content of the original UL transmission. For example, the transmission may include media access control (MAC) layer padding rather than relevant application layer data. The UE may then identify a DRX sleep period that includes the subframe where the ReTx would take place. In some cases, the DRX sleep period may include a subframe where the UE would otherwise receive an acknowledgement message (AM) from a base station. The UE may then enter a DRX sleep state. In another example, the DRX sleep period is based on the content of a received AM. If the UE receives an ACK, the UL ReTx may be unnecessary.
Abstract translation: 描述了使用增强的物理HARQ指示符信道（PHICH）解码来改善不连续接收（DRX）周期的方法，系统和设备。 用户设备（UE）可以基于原始UL传输的内容来确定不需要上行链路（UL）重传（ReTx）。 例如，传输可以包括媒体访问控制（MAC）层填充而不是相关的应用层数据。 然后，UE可以识别包括将发生ReTx的子帧的DRX休眠周期。 在一些情况下，DRX休眠期可以包括UE将否则从基站接收确认消息（AM）的子帧。 然后，UE可以进入DRX睡眠状态。 在另一示例中，DRX休眠期基于所接收的AM的内容。 如果UE接收到ACK，那么UL ReTx可能是不必要的。

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: Certain aspects of the present disclosure provide techniques for defending against false semi-persistent scheduling (SPS) activation detection and/or missed SPS release. According to certain aspects, a user equipment (UE) may detect one or more conditions for a semi-persistent scheduling (SPS) activation or release are met based on a downlink transmission, generate one or more metrics related to downlink transmission, and determine a valid SPS activation or release has occurred if the one or more metrics satisfy one or more criteria. According to certain aspects, a UE may determine a valid semi-persistent scheduling (SPS) activation has occurred, detect a number of PDSCH CRC failures, and implicitly declare an SPS release based on the detection.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for a user equipment (UE) to delay RLC retransmissions (e.g., during off-durations, including CDRX off-durations). According to aspects of the present disclosure, a UE may delay triggering an RLC retransmission of an RLC PDU until after a next opportunity for the UE to receive an RLC ACK of the RLC PDU. By delaying RLC retransmissions, a UE may be prevented from waking up from one or more CDRX off-durations and using power associated with waking up from the one or more CDRX off-durations.
