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.

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.

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).
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.

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.

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).
摘要:
Methods and apparatuses are provided for managing a performance level of a processing circuit, such as a modem, by making adjustments to one or more operating parameters provided to the processing circuit, such as a voltage supplied to the processing circuit and/or a clock frequency of the processing circuit. The processing circuit is adapted to monitor wireless wide area network (WWAN) protocol information. The processing circuit may adjust at least one operating parameter provided to the processing circuit in response to the monitored wireless wide area network (WWAN) protocol information.
