    Abstract: Some embodiments enable low power mode for wireless local area network (WLAN) subsystem of an electronic device to improve power usage at the electronic device and increase response time of the WLAN subsystem to prioritized application(s). For example, a method includes enabling a sleep mode of the WLAN subsystem of the electronic device. The electronic device maintains a connection with an access point of a wireless network during the sleep mode. The method further includes receiving a request from an application to communicate with the wireless network. The application is included in a list of prioritized applications. In response to determining that a metric associated with the sleep mode does not exceed a power budget, the sleep mode of the WLAN subsystem is suspended and the communication between the application and the access point of the wireless network is enabled (after the suspension of the sleep mode).

    Abstract: A compressor may obtain information indicative of a transmit delay representative of a time duration that elapses between creation (e.g. by the compressor) of a packet and the transmission of the packet, e.g. over a wireless link. The transmit delay may be determined based at least on information indicative of the uplink capacity of the cellular network. The uplink capacity may be determined/obtained based on the uplink throughput and uplink power headroom. When the compressor receives a negative acknowledgement transmission/packet from the decompressor, if the transmit delay is not greater than a specified threshold value, the compressor may process the received negative acknowledgement packet. If the transmit delay is greater than the specified threshold value, the compressor may first discard the buffered compressed packet scheduled to be transmitted next to the decompressor, and transmit an initialization and refresh (IR) or IR dynamic packet to the decompressor instead.

    Abstract: This disclosure relates to techniques for scheduling radio resource control connections between a wireless device and a network element of a network in advance. According to some embodiments, a wireless device may provide an indication of one or more types of upcoming data traffic to the network element. The network element may schedule one or more radio resource control connections for the wireless device based at least in part on the indication of one or more types of upcoming data traffic. The network element may provide an indication of the scheduled radio resource control connection(s) to the wireless device. The wireless device and the network may establish the scheduled radio resource control connection at the scheduled time.

    Abstract: Techniques discussed herein can facilitate power management at a User Equipment (UE) via selection of a power management stage based on a current power status. One example aspect is a UE comprising one or more processors configured to: monitor a temperature of the UE via one or more temperature sensors and a power usage of the UE; determine a power status of the UE based at least in part on the temperature of the UE and the power usage of the UE; select, based at least in part on the determined power status, a power management stage of a plurality of power management stages; and implement one or more power management techniques associated with the selected power management stage. A notification can be triggered to alert a user that the processor is implementing the one or more power management techniques prior to implementation.
