  • Publication number: 20130064153
    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).

  • Publication number: 20130039173
    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).

  • Publication number: 20130021995
    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.

  • Publication number: 20120176898
    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.

  • Publication number: 20110296064
    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.
