Abstract: Devices and methods for detection of active return loss for an antenna element of a plurality of antenna elements of a phased array antenna are provided. An exemplary device can convert a voltage differential at an input of a power amplifier (PA) to first current. The device can convert a coupled voltage corresponding to a signal transmitted from the PA to a respective antenna element, to a second current. The device can convert a reflected voltage corresponding to a signal reflected from the respective antenna element, to a third current. The device can convert the first current, the second current, and the third current to an output voltage at a generator output. The device can further have a controller that can adaptively generate codebooks for transmission based on the output voltage.

Abstract: Scheduling with split symbols for beam management is described. An apparatus is configured to receive, from a network node, DL signaling including a symbol in a first slot, and to measure a first measurement of a first beam during a first time portion, and a second measurement of a second beam during a second different time portion, of the symbol. The apparatus is configured to communicate, with the network node, using the first or second beam based on at least one of the first measurement or the second measurement. Another apparatus is configured to provide, for a UE, DL signaling including a symbol in a first slot, and to communicate, with the UE, using the first or second beam based on a first and/or second measurement. The first and second measurements are of first and second beams during a first and second different time portions of the symbol, respectively.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to determine a PSD based on a transmission power associated with transmission of an uplink signal. The apparatus may be configured to select one of a first beam or a second beam for the transmission of the uplink signal based on the PSD. The second beam may be wider than the first beam, and may be generated by a single antenna element of the apparatus. The apparatus may be configured to transmit the uplink signal using the selected one of the first beam or the second beam.

Abstract: A user equipment (UE) includes a first communication component configured to use a first frequency band, such as ultra-wide band (UWB), and a second communication component configured to use an intermediate frequency (IF) band that overlaps with the UWB band, such as an IF millimeter wave (mmWave) band. The second communication component conducts an IF signal along an internal signal conduction line that may interfere with UWB processing. A processor of the UE is configured to detect an indication of such interference, and, in response to the indication of interference, control the second communication component to adjust a characteristic of the IF band signal to mitigate the interference, such as by reducing its signal strength. The amount by which the IF band signal strength is reduced may be controlled to achieve a desired tradeoff between various performance metrics, such as power consumption and quality of service.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink communications with a receive beam that is formed using a set of antenna elements. The UE may measure, in parallel with the receiving the downlink communications, a channel impulse response (CIR) for each antenna element of the set of antenna elements in a round-robin fashion. The UE may generate a second receive beam or a transmit beam based at least in part on the CIRs for the set of antenna elements. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure generally relate to jamming detection for radio frequency (RF) front-end circuitry. For example, certain aspects provide an apparatus having a first counter configured to count a number of times that a power of a reception signal exceeds a first threshold. The apparatus also includes a second counter configured to count a number of measurements of the power of the reception signal. The apparatus further includes control logic having a first input coupled to an output of the first counter and having a second input coupled to an output of the second counter. The control logic is configured to determine an amount of jamming over a measurement window based on the number of times that the power of the reception signal exceeds the first threshold and on the number of measurements.
