Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a base station may participate in a one-shot initial access procedure involving a reconfigurable intelligent surface (RIS) divided into a number of sub-RISs, each sub-RIS associated with a different configuration for reflecting signaling from the base station. In some aspects, the base station may configure each sub-RIS to have a different frequency shift and transmit, to the UE, a parameter indicating a quantity of synchronization rasters associated with each of a set of beams that the base station may use as part of the one-shot initial access procedure. The UE may, for each beam, monitor a quantity of monitoring occasions corresponding to the quantity of synchronization rasters and transmit random access signaling to the base station based on which synchronization raster of which beam provides a greatest signal strength at the UE.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE determines whether to deactivate a semi-persistent (SP) channel state information (CSI) report associated with a first CSI report setting that is linked with a CSI report associated with a second CSI report setting. The second CSI report setting has a longer reporting periodicity than the first CSI report setting. The UE deactivates the SP CSI report, when at least the CSI report associated with the second CSI report setting is active.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to use one or more channel state information (CSI) omission configurations for omitting portions of a CSI report. For example, a UE may receive a trigger to report CSI, and the UE may identify that a payload of the CSI report exceeds a capacity of resources for transmitting the report. As such, the UE may determine to use one or more CSI omission configurations, where each CSI omission configuration may correspond to dropping different portions of the CSI report. The selection of the CSI omission configuration to use may be based on a set of parameters associated with CSI reporting. In some cases, the UE selects the CSI omission configuration based on an explicit indication from the base station. Additionally or alternatively, the UE may implicitly determine the CSI omission configuration based on the parameters.

The example method may further include determining, based at least in part on the measurement information, a set of weights for a plurality of reflective elements of the reconfigurable reflective surface to be used in reflecting communications between the first wireless device and a second wireless device.

Other aspects relate to receiving the CSI encoder output and assistance information, and transmitting the scheduling grant.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may communicate with a user equipment (UE) via a reconfigurable intelligent surface (RIS) which is capable of adjusting a reflection characteristic to reflect incident signaling in different directions. The base station and the RIS may establish a beamformed connection and, in some scenarios, the base station and the RIS may experience a beam failure. In such scenarios, the base station, the UE, and the RIS may participate in a two-step beam training procedure to reduce an amount of possible beam pair hypotheses that the communicating devices test in order to re-establish communication between the base station and the UE via the RIS. The two-step beam training procedure may include a first procedure in which the RIS selects a suitable beam toward the base station and a second procedure that leverages the selected beam.

Abstract: Methods, systems, and devices for wireless communication are described to support reducing a time domain selectivity of a downlink channel with multiple signal paths. A base station may spatially precode multiple channel state information reference signals (CSI-RSs) and transmit the spatially precoded CSI-RSs to a user equipment (UE), where at least one spatially precoded CSI-RS may correspond to each signal path. Based on the spatially precoded CSI-RSs, the UE may determine a mean or average Doppler shift for each signal path. The UE may transmit, to the base station, signaling indicative of the respective average Doppler shifts for each signal path. Based on the indication of the Doppler shifts, the base station may spatially and temporally precode one or more downlink transmissions to the UE, which may reduce the time domain selectivity of the downlink channel.

Abstract: Reinforcement learning of beam codebooks for millimeter wave and terahertz multiple-input-multiple-output (MIMO) systems is provided. Millimeter wave (mmWave) and terahertz (THz) MIMO systems rely on predefined beamforming codebooks for both initial access and data transmission. These predefined codebooks, however, are commonly not optimized for specific environments, user distributions, and/or possible hardware impairments. To overcome these limitations, this disclosure develops a deep reinforcement learning framework that learns how to optimize the codebook beam patterns relying only on receive power measurements. The developed model learns how to adapt the beam patterns based on the surrounding environment, user distribution, hardware impairments, and array geometry. Further, this approach does not require any knowledge about the channel, radio frequency (RF) hardware, or user positions.

Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, the described techniques provide for identifying interference signals on multiple layers or resources and determining whether the interference signals transmitted on a particular layer or resource were precoded using linear precoding (LP) or NLP. In this aspect, a receiving device may equalize signals received from a transmitting device (e. g., filter out interference signals) based on determining whether the interference signals were precoded using a first type of precoding (e. g., linear precoding (LP)) or a second type of precoding (e. g., NLP). In another aspect, the described techniques provide for performing interference measurements on signals precoded using NLP based on categorizing interference resources as being precoded using LP or NLP. In this aspect, a receiving device may perform and report measurements differently for interference signals precoded using LP and interference signals precoded using NLP.
