Abstract: One or more scheduling grants may be received from a Node B related to a plurality of uplink MIMO streams. A determination may be made as to a primary transport power and a primary transport block size for a primary stream. A secondary transmit power and a secondary transport block size for a secondary stream may also be determined. An enhanced relative grant channel from the Node B, as well as another E-RGC from a non-serving Node B may be received for each of the plurality of uplink MIMO streams.

Abstract: Systems, devices, and methods for managing multiple radio access bearer communications are provided. In one aspect, a device configured to communicate a voice and data communication via a wireless communication link is provided. The device includes a receiver configured to receive information selection criteria associated with a power limited condition. The device further includes a processor configured to detect the power limited condition. The processor is further configured to select information for transmission on a data channel, independent of the received information selection criteria.
Abstract: An amplifier with integrated filter (e.g., an LNA) is described. In one design, the amplifier may include a gain stage, a filter stage, and a buffer stage. The gain stage may provide signal amplification for an input signal. The filter stage may provide filtering for the input signal. The buffer stage may buffer a filtered signal from the filter stage. The amplifier may further include a second filter stage and a second buffer stage. The second filter stage may provide additional filtering for the input signal. The second buffer stage may buffer a second filtered signal from the second filter stage. All of the stages may be stacked and coupled between a supply voltage and circuit ground. The filter stage(s) may implement an elliptical lowpass filter. Each filter stage may include an inductor and a capacitor coupled in parallel and forming a resonator tank to attenuate interfering signals.
