Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reconfigurable intelligent surface (RIS) may select a weight vector, from a plurality of stored weight vectors, for enabling a spatially multiplexed communication, between a transmitter and a receiver, that includes two or more layers for each polarization of a plurality of polarizations for the spatially multiplexed communication. The RIS may receive the spatially multiplexed communication from the transmitter. The RIS may transmit the spatially multiplexed communication to the receiver in accordance with the weight vector. Numerous other aspects are described.

Weight vector selection for reconfigurable intelligent surface

Systems and methods for predictive coordination of ego radar and interferer radar parameters are disclosed. In some aspects, a processor associated with a first radar system transmitting a first radar waveform to detect a target may identify a presence of a second radar system transmitting a second radar waveform in a vicinity of the first radar system. The processor may further predict an upcoming interference by the second radar waveform of the detection of the target by the first radar system. In addition, the processor may, in response to the predicting the upcoming interference, determine an adjustment to a first parameter of the first radar waveform and/or to a second parameter of the second radar waveform.

A first wireless communication device configured to encode real samples of data to obtain encoded data based at least in part on adding one or more time domain complex samples to the real samples of the data, wherein a function of the one or more time domain complex samples is a known value, and wherein the function is a sum of exponentials of the one or more time domain complex samples. The first wireless communication device is configured to transmit, to a second wireless communication device, the encoded data.

Sample-level error-correcting code

Methods, systems, and devices for wireless communications supporting techniques for enhanced line-of-sight (LOS) communications with analog multi-path beamforming are described. A first wireless device may receive, from a second wireless device, an indication of a capability of the second wireless device to concurrently transmit first signaling in a first analog beamforming direction using a first transmission configuration indicator (TCI) state corresponding to a LOS mode, and second signaling in a second analog beamforming direction using a second TCI state corresponding to an indirect LOS mode. The first wireless device may then receive, from the second wireless device, a first downlink message in the first analog beamforming direction using the first TCI state concurrently with a second downlink message in the second analog beamforming direction using the second TCI state.

Systems and methods for adjusting radar transmission parameters based on congestion level measurements are disclosed. In some aspects, a congestion level of radar signals at a location in a vicinity of a radar source may be measured or otherwise determined. In some aspects, a transmission parameter of radar signals configured for transmission to the location by the radar source may be adjusted based on the congestion levels.
