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: This disclosure provides systems, methods, and apparatus for mobile transmit diversity. In one aspect, a wireless communication apparatus is provided. The wireless communication apparatus includes a transmit circuit configured to transmit wireless communications via either a first antenna or a second antenna. The wireless communication apparatus further includes a receive circuit configured to receive wireless communications using either the first antenna or the second antenna. The wireless communication apparatus further includes a controller configured to switch the transmit circuit and the receive circuit from transmitting and receiving wireless communications via the first antenna to transmit and receive wireless communications via the second antenna in response to detecting that a first receive power level of the first antenna is less than a second receive power level of the second antenna and a difference between the second receive power level and the first receive power level is greater than a threshold.
