Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a first set of random access occasions associated with a synchronization signal block that corresponds with a first receive beam of a base station. The UE may receive a second indication of a second set of random access occasions that are each associated with a respective receive beam of a set of receive beams of the base station. Each receive beam of the set of receive beams may spatially overlap a portion of the first receive beam. The UE may transmit the random access message using a selected random access occasion of the second set of random access occasions.

Abstract: Methods, systems, and devices for wireless communications are described. One or more UEs communicating over sidelink may indicate transmit and receive categories to other UEs. A first UE may receive, in a sidelink communication message, an indication of a receive category of a second wireless device. The first UE may then transmit a shared sidelink channel message to the second wireless device based on the receive category of the second wireless device. In another case, a first UE may receive, in a sidelink communication message, an indication of a transmit category of a second wireless device. The first wireless device may then compare the transmit category of the second wireless device with a receive category of the first wireless device. The first wireless device may determine whether to decode a shared sidelink channel message from the second UE based on the comparing.

Abstract: This disclosure provides methods, devices and systems for pre-compensation of downlink communication based on a transmission of a request for the pre-compensation from a user equipment (UE). For example, the UE may determine an impairment at the UE that has a greater severity (a greater impact on downlink communication) or is associated with a greater amount of resources for processing relative to a remainder of a set of impairments that is experienced at the UE and the UE may transmit a request for pre-compensation of the impairment by a base station. The base station may transmit feedback to the UE indicating a confirmation of pre-compensation for the impairment by the base station or to deferment of compensation for the impairment back to the UE. If the base station acknowledges pre-compensation for the impairment, the base station may pre-compensate a downlink transmission to the UE for the impairment.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration of random access resources from a base station. The configuration may indicate a quantity of a plurality of random access preambles, a quantity of a plurality of synchronization signal blocks (S SBs), and a quantity of random access preambles per SSB. The received configuration may indicate that each random access preamble of the plurality of random access preambles is available to the UE in the random access occasion for each SSB of a plurality of SSBs transmitted by the base station. The UE may select a random access preamble of the plurality of random access preambles based at least in part on the received configuration and transmit the selected random access preamble to the base station in the random access occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit control signaling including a beam shaping configuration to a channel engineering device. The channel engineering device may apply the beam shaping configuration during a time period in which the base station is communicating with a user equipment (UE). The beam shaping configuration may include one or more parameters that modify one or more deflection settings at the channel engineering device to adjust an electronic metamaterial of the channel engineering device to focus received signal energy, reflect received signal energy, refract received signal energy, filter received signal energy, or any combination thereof. The base station and one or more UEs may communicate using the channel engineering device based on the beam shaping configuration.

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. 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.
