Abstract: Methods, systems, and devices are described for managing power of a user equipment (UE). A UE modem may determine the state of charge of the battery to determine that the battery is in one of two or more charge state levels, and may invoke one or more modem power saving modes based on the charge state level. Power saving modes may include, for example, reducing a number of available receive chains in a UE, initiating a time delay between one or more frequency scan requests performed by the UE, reducing a rate of neighbor search requests performed by the UE, providing a buffer status report (BSR) parameter that indicates a reduced amount of buffer data relative to an actual amount of buffer data for the UE, and/or adjusting a maximum transmit power level for an uplink channel.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus is a UE. The UE transmits data packets. The UE determines to implement a flow control to reduce a transmission rate of the data packets. The UE determines whether the data packets include known or potential real-time data packets. The UE refrains from implementing the flow control to reduce the transmission rate of the known/potential real-time data packets when the data packets include known/potential real-time data packets.

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.

Abstract: A mobile device determines that a primary cell (PCell) and a secondary cell (SCell) belong to a same multicast-broadcast single frequency network (MBSFN) area or that the PCell and the SCell can broadcast the same service. The mobile device determines a communication state of the SCell. If the SCell is active, the mobile device compares signal quality on the PCell and the SCell and selects to decode broadcast content on the PCell or the SCell. If the communication state indicating the SCell is deactivated or released, the mobile device switches to decode the broadcast content on the PCell. If the SCell is released and if the mobile device determines that the PCell is also released, then the mobile device switches to decode the broadcast content on the PCell and initiates a neighbor cell search.

Abstract: Techniques for optimized HARQ recombining are provided. In one exemplary embodiment, a method for wireless communication comprises receiving a broadcast message to determine a timing of a transmission window, receiving at least one transmission within the transmission window, and determining whether the at least one transmission is successfully decoded. The method further comprises instructing a lower protocol layer to ignore remaining transmissions within the transmission window upon a determination that the at least one transmission is successfully decoded, wherein the remaining transmissions and the at least one transmission comprise duplicate copies of a message segment.
