Abstract: Aspects of the present disclosure relate to apparatuses and methods for performing adaptive receive-diversity (RxD) to improve power consumption using multiple antennas/receivers. In one aspect, a first receive-diversity (RxD) state is enabled at an access terminal utilizing two receive chains for a communication link. Link quality metrics corresponding to the communication link are determined. The access terminal selectively switches from the first RxD state to a second RxD state utilizing three or more receive chains dependent upon the link quality metrics, such that the energy per bit of the second RxD state is more energy efficient than the energy per bit of the first RxD state.

Abstract: Aspects of the present disclosure relate to wireless communication devices and methods configured to operate with multiple communication protocols in tune-away operations. Some aspects of the present disclosure may improve the legacy tune-away operations at an access terminal. An access terminal establishes a call utilizing a first communication protocol, tunes away from the call to receive cell signaling utilizing a second communication protocol, and tunes back to the call utilizing the first communication protocol. Following the tuning back, during a first predetermined number of subframes and if the size of a reverse link (RL) packet is smaller than a first packet size and larger than a second packet size, the access terminal forces the RL packet to be a low latency (LoLat) packet.

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: System(s) and method(s) are provided for handover of a mobile terminal in a wireless communication system. Handoff resolution relies on both a downlink channel quality indication between a serving base station and the mobile terminal, and uplink channel quality indications amongst the terminal and a measurement set of target base stations. To generate UL channel quality indicators, the mobile station conveys a narrowband or broadband sounding reference signal, and serving and target base stations measure UL and DL performance metrics (e.g., RSRP, RSSI, or RSOT). In backward handover, UL channel state information from target cells is received at the serving base station through backhaul communication, and handoff is resolved based on both UL and DL quality reports. In forward handover, the set of UL quality reports are conveyed to the mobile station to determine a target cell for handoff.

Abstract: Apparatus and methods are disclosed for gating reverse link transmissions of ¼ rate, ½ rate, ¾ rate, and/or full rate frames in a wireless communication system, such that an access terminal can reduce its power consumption. The gating or discontinuous transmission (DTX) of the reverse link transmission may be conditionally applied based on factors such as the state of the access terminal, the filtered average power of gated the transmissions, or other factors. Further, the gating utilizes a pattern configured to be orthogonal to a pattern utilized for 1x smart blanking, and further configured not to interrupt forward link or reverse link power control signaling. Other aspects, embodiments, and features are also claimed and discussed.
