Abstract: Aspects described herein relate to encoding, based on an estimated channel matrix of a reference signal received from a base station, channel state information (CSI) using a machine learning (ML)-based CSI encoder, transmitting, to the base station, an output of the ML-based CSI encoder and assistance information related to the estimated channel matrix, and receiving, from the base station, a scheduling grant for a downlink channel having at least one parameter that is based on the output of the ML-based CSI encoder and the assistance information. Other aspects relate to receiving the CSI encoder output and assistance information, and transmitting the scheduling grant.

Abstract: Techniques for channel state feedback using sensing reference signals are disclosed. The techniques can include identifying a channel state information (CSI) report configuration based on CSI reporting configuration information received from a radio access network (RAN) node of a RAN, based on the CSI report configuration, identifying a set of basis reference signals to be measured on a wireless channel of the RAN, wherein the set of basis reference signals includes one or more sensing reference signals, measuring the set of basis reference signals to obtain channel state measurements, determining channel state information based on the channel state measurements, and transmitting a CSI report including the channel state information to the RAN node.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process includes receiving a signal comprising a slot including at least one shared signal resource. The process further includes determining whether the slot is allocated for sensing and communications or is allocated for communications. The process further includes determining whether to demodulate the at least one shared signal resource using at least one sensing reference signal (RS) resource or at least one communication RS based whether the slot is allocated for sensing and communications or is allocated for communications.

Abstract: Aspects presented herein may improve the performance and accuracy of a UE positioning based on RIS, such as when the RIS has a limited number of control voltage sets available. In one aspect, a UE obtains an indication of beam pattern information for a set of DL beams for a network entity, where the set of DL beams is associated with an RIS. The UE adjusts a first transmission angle for a set of UL beams based on the beam pattern information and measurement for the set of DL beams, where the first transmission angle for the set of UL beams is adjusted to proximately align with a second transmission angle of the set of DL beams from the RIS. The UE transmits, via the RIS, the set of UL beams to the network entity based on the adjusted first transmission angle.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) determines a transmit power of at least one sensing reference signal (S-RS) transmitted by a network node, wherein the transmit power of the at least one S-RS is determined based on a transmit power offset relative to a transmit power of a reference channel or reference signal transmitted by the network node, and determines an enhanced channel estimate of the at least one S-RS based on the transmit power of the at least one S-RS.
