Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to intelligent resource assignment to increase throughput in LTE multiple input multiple output (MIMO) and carrier aggregation (CA) capable devices. In certain aspects, a MIMO and CA capable wireless communication device communicates with a base station (BS) on multiple component carriers (CCs) through multiple radio frequency (RF) chains. In such aspects, the device tentatively switches one or more first RF chains, not assigned to a first CC of the multiple CCs, to the first CC for evaluating a rank of the first CC. The device then determines that the first CC has a higher rank indication (RI) with the one or more RF chains. The device subsequently evaluates one or more performance factors, in conjunction with the higher rank, based on which the device then additionally assigns one or more second RF chains to the first CC.

Abstract: Techniques are provided to initiate signal transmissions for possible opportunistic reception by a mobile device, and/or to initiate opportunistic reception of signal transmissions for use in mobile device position location estimation. For example, a mobile device may use assistance data to identify a first signal to be transmitted over a first frequency band and a second signal to be transmitted over a second frequency band during a specific period of time. At least a portion of the second frequency band may be outside of the first frequency band. The mobile device subsequently attempts to opportunistically receive at least the first signal and the second signal via a receiver tuned to a reception frequency band that encompasses at least the first frequency band and the second frequency band. The mobile device may then process the opportunistically received signals to obtain measurements corresponding to at least the first and second signals.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. A wireless communication device may determine a plurality of differential back-off values based at least in part on at least one of a set of parameter values relating to one or more of a plurality of uplink carriers associated with uplink carrier aggregation or any uplink grants associated with the plurality of uplink carriers. The plurality of differential back-off values may relate to a specific absorption rate (SAR) back-off or a thermal back-off of the wireless communication device. The wireless communication device may apply the plurality of differential back-off values to a respective plurality of transmit powers associated, respectively, with the plurality of uplink carriers.

Abstract: Methods, systems, and devices for wireless communication by a user equipment (UE) are described. A UE may be operating in a downlink carrier (DL) carrier aggregation (CA) mode, which may include a first component carrier and a second carrier component of a set of component carriers. The UE may determine the second component carrier satisfies throughput requirements associated with an uplink (UL) data transmission. The UE may determine, a transmission current consumption relationship between the first component carrier and the second component carrier. The UE may determine, based on the transmission current consumption relationship, whether to switch the anchor carrier from the first component carrier to the second component carrier. When the UE determined to switch the anchor carrier, the UE may modify a measurement report to satisfy a condition for switching the anchor carrier from the first component carrier to the second component carrier.
