    摘要: 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.

    摘要: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus stores data packets in a buffer. 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.

    摘要: 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.
