A processor can include various processing pipelines that perform different data processing operations, with different pipelines having dedicated logic and memory circuits. A power management circuit can determine when to supply power to various pipelines, including the logic and memory circuits of the various pipelines, depending on a current operating mode of the processor. When a memory circuit transitions to a lower power state such as a sleep state, data can be saved to a different memory circuit that is not transitioning to a lower power state, and when the memory circuit is powered up again, the data can be restored from the different memory circuit.

Adaptive wake-up for power conservation in a processor

A wireless communication system may adapt physical downlink control channel (PDCCH) monitoring behaviors using downlink control information (DCI). The change in monitoring behavior may be skipping or switching. The timeline for applying switching or skipping may be applied after a reference point and a processing time. In some embodiments, the processing time may be either based on UE processing, network processing, or a combination.

Application timeline with unified design for active mode user equipment power saving for apparatuses, systems, and methods

Aspects of the present disclosure provide techniques for the user equipment (UE) to select a power management mode from a plurality of power management modes supported by the UE based on decoding of a portion of the downlink subframe. For example, when the UE receives a subframe from a base station, the UE may decode a control channel region of the subframe to determine whether the subframe includes a channel grant allocated to the UE. If no channel grant is included in the subframe, the UE may select a power management mode for the UE from the plurality of power management modes supported by the UE that maximizes the UE's sleep opportunities while balancing the deficient performance costs.

Techniques to control UE power-usage on shared downlink shared channel region of a subframe

Managing of secondary carriers for a multicarrier user equipment (UE) is described in which the UE initiates or provides input for activation and deactivation of selected secondary cells in a carrier aggregation depending on allocation or provisioning of UE radio frequency resources.

UE-initiated dynamic activation and de-activation of secondary carriers

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a stream of RTP data packets over a wireless channel and applies ROHC decompression to decode the packets. Upon a failure of ROHC decompression, the apparatus identifies the RTP sequence number (SN), RTP Timestamp (TS), and PDCP receive time (RT) of a prior successfully decoded packet, and the PDCP SN and PDCP RT of the failed packets. Using the identified information, the apparatus estimates the RTP SN and RTP TS of each of the failed packets. The apparatus decodes the packets using the estimated information.

Call continuity in high uplink interference state

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.

Techniques for controlling power usage based on network parameters

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). For example, the mechanisms may be used with LTE and other RATs where Carrier Aggregation is used for simultaneous voice and LTE (SV-LTE) applications.

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.

Embodiments include systems and methods for managing tune-way in a multi-subscription communication device. A processor of a multi-subscription communication device may determine a first signal strength of a first cell signal and a second signal strength of a second cell signal. The processor may perform a tune-away procedure to a weaker of the first cell signal and the second cell signal. Embodiments may include determining signal strengths of each component carrier of the first cell signal and the second cell signal.

Managing tune-away in a multi-subscriber identity module communication device

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.

Delay based active queue management for uplink traffic in user equipment

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.

Context establishment in marginal grant conditions

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.

Method and apparatus for excluding guaranteed bit rate traffic bearers from LTE UL flow control

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.

Power optimization using scheduling request delay

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).
