    Abstract: Techniques for improving rejection of out-of-band interference in a noise-cancelling receive architecture. In an aspect, capacitors blocking in-band signals and passing through out-of-band signals destructively couple an auxiliary mixer output to a mixer output. In a further aspect, cross-coupling capacitors are provided to couple a first signal path with a second signal path of the noise-cancelling receive signal path. Baseband poly phase cross-coupling blocker filtering is further provided for out-of-band interference cancellation to create notch responses at blocker offset frequencies. The techniques disclosed may readily be adapted for multi-phase local oscillator systems.

    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may dynamically select subsets of antenna elements within an array based on power consumption and link performance and/or a configuration of components at the wireless device. For example, a wireless device may identify an antenna array having multiple antenna elements, and the wireless device may select respective subsets of antenna elements (e.g., subarrays) for uplink and downlink transmissions. In such cases, the selection may be based on a tradeoff of power consumption at the device and link performance. Additionally or alternatively, the selection may be based on a configuration and/or constraints on a number of radio frequency (RF) components of the wireless device. The wireless device may communicate based on the dynamic selection of different subsets of antenna elements of an array for uplink and downlink communications.

    Abstract: Certain aspects are directed to an apparatus configured for wireless communication. The apparatus may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the one or more processors are configured to cause the apparatus to obtain a sample of an analog signal. In some examples, the one or more processors are configured to cause the apparatus to output the sample to an analog-to-digital converter (ADC) via one of at least a first path or a second path based at least in part on whether the sample satisfies a first threshold condition or a second threshold condition.
