Abstract: A method, an apparatus, and a computer program product are provided. The apparatus may be configured to establish a first call for a first subscription, and accept a second call for a second subscription while maintaining the first call. A single transmit chain may be used to transmit uplink traffic associated with the first call and uplink traffic associated with the second call. A timesharing schedule for the transmit chain may determine when the uplink traffic associated with the first call is transmitted and when the uplink traffic associated with the second call is transmitted on the transmit chain. Downlink traffic associated with the first and second calls may be received using different receive chain. Downlink traffic associated with the first and second calls may be received using the same receive chain.

Abstract: Aspects of the present disclosure provide an apparatus and method for modem-assisted video telephony. As one example, a user equipment (UE) utilizes a modem to perform video telephony (VT) communication with a remote device through a wireless network. The UE determines a network metric indicative of congestion in the wireless network based on modem information obtained from the modem, independent of feedback information received from the remote device. The UE dynamically adjusts a data rate of the VT communication by an amount proportional to a quantity based on the network metric.

Abstract: Methods, systems, and devices are described for managing power consumption in a modem of a mobile device. A receive power associated with a receiver of the modem may be measured during a scheduled power-up of the modem associated with checking for paging messages. A power consumption metric associated with transmitting a pending wireless data transaction at a transmitter of the modem may then be estimated based on the measured receive power associated with the receiver. A determination of whether to transmit the pending wireless data transaction at a first time may then be made based at least in part on the estimated power consumption metric.

Abstract: Access terminals are adapted to regulate power in wireless receiver circuits. In one example, access terminals include a communications interface with at least one wireless receiver circuit. A processing circuit coupled with the communications interface can determine that data is not expected to be received by the access terminal for a period of time while operating in a connected mode. One or more components of the wireless receiver circuit, including a low noise amplifier (LNA) of the wireless receiver circuit, can subsequently be powered down (e.g., set to a passive state) in response to such a determination. Other aspects, embodiments, and features are also claimed and described.

Abstract: In a high data rate communication system capable of variable rate transmission, an open loop rate control can be adjusted with a closed loop rate control to maximize throughput. An access point generates interleaved multi-slot packets that allow an access terminal to transmit indicator messages to the access point in accordance with recently received data carried within slots of the multi-slot packets.
