Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may include a first set of antenna arrays disposed in a first shape and a receiving device may include a second set of antenna arrays disposed in a second shape. A first axis that intersects an antenna array of the first set of antenna arrays and a centroid of the first shape may be offset from a vertical direction by a first angular offset. A second axis that intersects an antenna array of the second set of antenna arrays and a centroid of the second shape may be offset from the vertical direction by a second angular offset that is different than the first angular offset. The transmitting device may transmit signaling to the receiving device using the first and second sets of antenna arrays, respectively based on difference between the first and second angular offsets.

Abstract: Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

Abstract: Methods, systems, and devices for wireless communications are described. A codebook adaptation may be performed for a flexible user equipment (UEs) to determine a codebook for a physical configuration of the UE. For example, if the UE determines that the physical configuration does not correspond to a pre-loaded codebook in its memory, the UE may provide information about the physical configuration to a base station to determine a corresponding codebook. Additionally, the UE may request that the base station provide channel information to assist with the codebook determination. In some cases, this request may indicate for the base station to allocate a specific number of channel state information reference signal symbols that the UE can use for the codebook determination. Additionally or alternatively, the UE may generate the codebook internally and then signal to the base station a request for a beam refinement procedure with the generated codebook.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicating a first uplink message using a first uplink carrier and a first timing advance (TA) value associated with a first transmission configuration indicator (TCI) state and a second uplink message using a second uplink carrier and a second TA value associated with a second TCI state for the UE. The UE may receive a timing advance group (TAG) configuration which indicates a TA value to apply for a supplementary uplink (SUL) carrier of the serving cell, which is one of the first TA or second TA values. The UE may then transmit a SUL message using the SUL carrier of the serving cell in accordance with the TA value determined for the SUL carrier based on the TAG configuration for the UE.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a first device may calculate hybrid beamforming parameters for a second device. The first device may calculate the hybrid beamforming parameters based on an estimation of channel information associated with at least a portion of a communication link at the second device via a machine learning model. Inputs to the machine learning model may include measured model parameters based on measurements performed by one or more other devices. The first device may transmit a message to the second device to indicate the hybrid beamforming parameters, which may include an input for a beam refinement process. The second device may perform the beam refinement process based on the hybrid beamforming parameters to identify one or more beams. The first and second devices may communicate using the one or more beams based on the beam refinement process.

Abstract: Aspects of the present disclosure provide techniques for utilizing road side unit (RSU) that may be stationary units or mobile user equipments (UEs) (e.g., part of a vehicle) for managing scheduling requests from one or more UEs for side-link cellular vehicle-to-everything (CV2X) communication between UEs. To this end, an RSU may determine characteristics associated with the scheduling requests (e.g., traffic type, latency requirements, etc.) to allocate resources in the resource pool to the one or more UEs that comply with the half-duplex constraints.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a digital repeater may receive, from a control node, a configuration that indicates a digital processing operation, wherein the digital processing operation comprises a digital processing option selected from a plurality of digital processing options. The digital repeater may receive a first signal. The digital repeater may perform the digital processing operation on the first signal to generate a second signal, wherein the second signal comprises a re-generated version of the first signal. The digital repeater may transmit the second signal. Numerous other aspects are provided.

Abstract: A first wireless communication device, such as a base station, may include separate transmit and receive antenna arrays. The separation between the transmit and receive antenna arrays may cause a direction of a transmit beam formed at the transmit antenna array to be different from a direction of a receive beam formed at the receive antenna array. The transmit and receive beams may be formed for communication with a second wireless communication device, such as a user equipment (UE). The described aspects enable the first wireless communication device to monitor a difference between a first direction of the transmit beam and a second direction of the receive beam. The first wireless communication device may transmit an indication of a beam correspondence failure to the second wireless communication device when the difference between the first and second directions is greater than or equal to a beam correspondence threshold.
