Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a user equipment (UE) device within a wireless communication system may select a desired number of antenna elements for receiving a communication from another device based on a channel quality determination. The UE receives a first signal from a transmitting device using a first beam. The UE determines a channel quality metric and compares the channel quality metric with a channel quality threshold. The UE adjusts a number of antenna elements used for beamformed wireless communication between the transmitting device and the UE based on the comparison between the channel quality metric and the channel quality threshold. Based on this adjustment, the UE receives a second signal from the transmitting device using a second beam that has a different number of antenna elements than the first beam.

Abstract: This disclosure provides methods, devices and systems for reducing PAPR in wireless communications. Some implementations more specifically relate to suppressing the amplitudes of a data signal that exceed a threshold amplitude level. In some implementations, a transmitting device may detect one or more peaks associated with a data signal to be transmitted to a receiving device. A peak may be any sample of a data signal having an amplitude that exceeds a threshold amplitude level. The transmitting device generates peak suppression information indicating the amplitude, a phase and a position of each of the samples associated with the detected peaks. The transmitting device adjusts the data signal by reducing the amplitudes associated with the detected peaks and transmits the adjusted data signal, with the peak suppression information, to the receiving device. In some implementations, the transmitting device may compress the peak suppression information to reduce the overhead of the transmission.

Abstract: A system that incorporates the subject disclosure may include, for example, a process that includes adjusting a filter in electrical communication between an input terminal and a demodulator. The filter is applied to an information bearing signal, e.g., to mitigate interference, received at the input terminal, resulting in a filtered signal. An error signal is received, indicative of errors detected within information obtained by demodulation of a modulated carrier of the filtered signal. A modified filter state is determined in response to the error signal and the filter is adjusted according to the modified filter state, e.g., to improve mitigation of the interference. Other embodiments are disclosed.

Abstract: The techniques described herein provide procedures at user equipment (UEs) for performing channel state information (CSI) reporting and sounding reference signal (SRS) transmissions based on an ultra-reliable low latency communication (URLLC) block error rate (BLER) target and for reliably receiving PDCCH transmissions.

For SRS transmissions, a UE may be configured to transmit SRS based on an SRS configuration determined based on a BLER target. For receiving PDCCH transmissions, a UE may be configured to receive and combine DCI received from multiple base stations.
