Abstract: Methods, systems, and devices for wireless communication are described. A first device may transmit an indication of a first set of signal strength metrics for signal strengths of transmit beams of a second device using receive beams of the first device and a second set of signal strength metrics for signal strengths of transmit beams of the first device using the receive beams of the first device. The first device may determine, for one or more signal strength metrics in the first set of signal strength metrics, the second set of signal strength metrics, or both, a change in the corresponding signal strength. The first device may transmit, based at least in part on the determining, an indication of the change in the corresponding signal strength for each of the one or more signal strength metrics.

Abstract: Techniques for wireless communications are described. A demodulation reference signal generated using user information and a noncoherent modulation technique may be communicated between wireless devices. A data sequence may be extracted from the demodulation reference signal based on demodulating the demodulation reference signal using the noncoherent modulation technique and decoding the demodulation reference signal. The data sequence may be used to reconstruct a version of the demodulation reference signal used to descramble a received version of the demodulation reference signal. The descrambled demodulation reference signal may be used to estimate a data channel between a transmitting device and a receiving device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a first set of signal strength metrics for signal strengths of transmit beams of a base station using receive beams of the UE. The UE may identify a second set of signal strength metrics for signal strengths of transmit beams of the UE using receive beams of the UE. The UE may transmit an indication of the first set of signal strength metrics and the second set of signal strength metrics to the base station. The UE may communicate with the base station based at least in part on the indication.

Abstract: Methods, systems, and devices for wireless communications are described. The following relates more specifically to hierarchical hybrid automatic repeat request (HARM) for multi-level coding with multi-level sequential demodulation and decoding and code block grouping per decoding level. A user equipment (UE) may receive, during a first time period, a transmission from a base station including a first and second code block group (CBG) with codeblocks associated with a first and second decoding level. The UE may fail to decode the first CBG, may not decode the second CBG, may store post processing samples for the second CBG, and may transmit a feedback message to the base station. The base station may retransmit the first CBG and new data on the second CBG in a second time period. The UE may decode the first CBG and use the post processing samples to decode the second CBG from the first time period.

Abstract: A base station transmits a first transmission using a first directional beam and determines an equivalent isotropic radiated power (EIRP) relationship between the first transmission and a physical downlink shared channel (PDSCH) for a user equipment (UE). The base station transmits, to the UE, an indication of the EIRP relationship between the first transmission and the PDSCH. Then, the base station transmits the PDSCH to the UE using the second directional beam. The UE uses the indication of the EIRP relationship to receive the PDSCH from the base station over the second directional beam.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a first demodulation reference signal for each of one or more sub-bands and configured in accordance with a first one or more demodulation reference signal configurations. The UE may select a second demodulation reference signal configuration from a respective set of second demodulation reference signal configurations for each of the one or more sub-bands and may transmit an indication of the second demodulation reference signal configuration for each of the one or more sub-bands. The base station may receive the indication and may transmit, to the UE, a second demodulation reference signal for each of the one or more sub-bands and configured in accordance with the second demodulation reference signal configuration for each of the one or more sub-bands.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may encode a set of bits to transmit to a receiving device based on a repetition factor. The transmitting device may map, based on the repetition factor, the set of encoded bits to a subset of subcarriers such as adjacent subcarriers of a set of subcarriers. The transmitting device may generate a signal including the set of encoded bits based on the mapping, and transmit the generated signal to the receiving device. The receiving device may receive a modulated signal from the transmitting device, and identify, based on a repetition factor, a subset of subcarriers including adjacent subcarriers of a set of subcarriers associated with the modulated signal. The receiving device may average the subset of subcarriers including the adjacent subcarriers, and demodulate the modulated signal in accordance with the averaged subset of subcarriers including the adjacent subcarriers.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may measure a received power of one or more reference signals, such as channel state information (CSI) reference signals (CSI-RSs) or synchronization signal blocks (SSBs), transmitted by a base station for a beam management procedure. The UE may determine a set of channel statistics associated with a channel used by the base station to transmit the one or more reference signals based on performing the beam management procedure. The UE may transmit a report to the base station, the report including at least an indication of the received of the one or more reference signals and the set of channel statistics. The base station may select a beam or a channel for communication with the UE based on at least the indication of the received power and the set of channel statistics.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify conditions associated with one or more physical channels, for example, a set of resources with which the UE may be configured to communicate with a base station. The UE may determine whether to enable a reduced power mode based on the conditions satisfying certain criteria, for example, the set of resources corresponding allocated for particular transmissions. The UE may identify that the conditions satisfy corresponding criteria, and the UE may determine to enable the reduced power mode. The UE may accordingly modify operations one or more components of a receive chain of the UE. The UE may determine to disable the reduced power mode based on the conditions failing to satisfy the criteria, and the UE may modify operations of the one or more components of the receive chain accordingly.
