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: 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: A method for power optimization by an apparatus is disclosed. The method includes identifying one or more network parameters that affect one or more of a processing rate and a power usage of the processor in a connected state. The method also includes identifying a trigger event for the one or more network parameters. The method further includes adjusting a performance of the processor in the connected state when the trigger event occurs.

Abstract: Certain aspects of the disclosure relate generally to techniques for managing scheduling requests (SRs) for resources for uplink transmission. For example, certain aspects of the present disclosure relate to a method for wireless communication including determining a transmit opportunity for transmitting SR for uplink resources based, at least in part, on a discontinuous reception (DRX) time cycle. According to certain aspects, a user equipment (UE) may delay transmitting the SR based on the DRX time cycle to prevent repeated interruption of the DRX cycle that may reduce benefits of the power-saving DRX scheme.

Abstract: Methods, systems, and devices are described for data transmission using header compression techniques that may include dropping all of a portion of a payload for one or more Protocol Data Units (PDUs). A wireless communications device may determine that a robust header compression (RoHC) mode is in an initialization and refresh (IR) state, indicating a full Packet Data Convergence Protocol (PDCP) Protocol Data Unit (PDU), including complete header information, is to be transmitted. The wireless communications device may identify that a payload of at least part of a media frame is to be transmitted in the IR state, and drop at least part of the payload when a probability of segmenting the payload during transmission in the IR state exceeds a threshold.

Abstract: Certain aspects of the present disclosure may help reduce power consumption by allowing a UE to remain in a low power state by not attempting to decode ACK/NACK transmissions after receiving a positive acknowledgement (ACK).

Abstract: Certain aspects of the disclosure relate generally to uplink flow control of wireless devices for mitigation of overload issues. A user equipment (UE) may reduce an average transmit power for the uplink channel based on whether an overload metric (e.g., temperature metric) exceeds a threshold value. The UE may perform duty cycling for an uplink control channel when an overactive uplink control channel is a dominating factor in a thermal issue. The UE may further reduce a maximum power transmit limit (MTPL) for one or more uplink channels, such as physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH).

Abstract: Techniques are provided for controlling downlink data transfer during carrier aggregation. For example, a method may control a secondary component carrier downlink (DL) in a wireless communication network using carrier aggregation. The method may include detecting, by a mobile entity, an event indicating a resource constraint at the mobile entity related to a data transmission from a base station to the mobile entity on a secondary component carrier of a carrier aggregation enabled connection. The method may include, in response to detecting the event, controlling the data transmission by signaling a status of the secondary component carrier DL to the base station.

Abstract: A technique for uplink data throttling includes buffer status report (BSR) scaling. A target data flow rate may be determined based on at least on condition of a wireless device. The buffer status report may be adjusted to cause the target flow rate and transmitted by the wireless device. The wireless device may then receive a flow control command based on the buffer status report.

Abstract: Techniques for controlling internal operation of a user equipment (UE) based on physical layer (PHY) parameters of a wireless network are disclosed. The PHY parameters may include a system bandwidth, an uplink-downlink configuration, a number of antennas, a number of carriers, etc. In one design, the UE may receive system information from the wireless network. The UE may obtain at least one PHY parameter of the wireless network, at a physical layer on the UE, based on the system information and/or other signaling. The UE may provide the at least one physical layer parameter to at least one entity (e.g., a memory and flow controller, a clock controller, a thermal mitigator, an application processor, etc.) within the UE for use to control internal operation of the UE.

Abstract: Certain aspects of the present disclosure relate to wireless communications and methods and apparatus for downlink flow control at a user equipment (UE). Aspects generally include monitoring, by a UE, one or more parameters related to the UE, and selectively dropping received packets based on the one or more parameters in order to trigger a rate control mechanism. Selectively dropping received packets may occur at a Packet Data Convergence Protocol (PDCP) layer in order to reduce a corresponding transmission control protocol (TCP) throughput. Accordingly, packets may be selectively dropped prior to reaching an applications processor.

Abstract: The described aspects include methods and apparatus for aligning a voice over data vocoder timing at a user equipment (UE). A scheduling interval timing is determined at the UE, and a timing of a vocoder of the UE can be aligned based on the scheduling interval timing. The UE transmits one or more packets generated by the vocoder according to the timing in at least one transmission period related to the scheduling interval timing. Thus, time delay between packet generation and transmission can be minimized.

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: Aspects of the present disclosure generally relate to wireless communication and to mechanisms designed to help improve dynamic sharing of one or more receive chains among different radio access technologies (RATs).

Abstract: Disclosed are methods and apparatus for improving the performance of a user equipment handover during a data call. In one aspect, a source base station determines to handover user equipment (UE) to a target base station. The source base station first determines whether the UE is in a data call prior to the handover. The source base station then modifies one or more of connected mode discontinuous reception (CDRX) and semi-persistent scheduling (SPS) parameters with the UE based on determining to handover the UE and determining that the UE is in the data call.

In addition, the apparatus determines a delay of at least one data packet of the data packets in the buffer. Furthermore, the apparatus controls a TCP data flow rate based on the determined delay. The apparatus may also store ACKs in a second buffer and drop an ACK of the stored ACKs when one of a number of stored ACKs is greater than a first threshold or a size of the stored ACKs is greater than a second threshold.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a probability of occurrence of an event expected to occur within a period of time is determined, where the event comprises one or more of a tune-away event and a suspension event. One or more transmission control protocol parameters are manipulated before the occurrence of the event when the probability of occurrence exceeds a threshold to increase a retransmission time out parameter value, or to maintain a desirable congestion window size. The transmission control protocol parameters may be manipulated by delaying, duplicating or dropping acknowledgements and/or by selectively dropping received packets before, during, or after the event.
