Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication by a user equipment, comprising receiving a first configuration indicating a scheduled time at which a signal is to be communicated between the apparatus and a network entity, the scheduled time being within a time interval associated with a first network energy state of the network entity. The implementations further include receiving a second configuration mapping the signal with a second network energy state of the network entity. The implementations further include receiving or transmitting the signal at the scheduled time while the network entity is in the second network energy state based on the second configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, downlink control information (DCI) associated with a reconfigurable intelligence surface (RIS) beam training, wherein the DCI configures an RIS controller and the UE for the RIS beam training. The UE may transmit, to the base station, a report based at least in part on the DCI associated with the RIS beam training. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a controller of a reconfigurable intelligent surface (RIS) may receive a signal including a plurality of demodulation reference signals (DMRSs). The controller of the RIS may configure a set of reflective elements of the RIS such that a first DMRS of the plurality of DMRSs is reflected using a first beamformer and a second DMRS of the plurality of DMRSs is reflected using a second beamformer different than the first beamformer. Numerous other aspects are described.

Abstract: Embodiments described herein provide for an RIS-aided determination of the location of mobile device that enables the signal reflected by the RIS to be identified through channel estimation. More specifically, an Orthogonal Cover Code (OCC)-based approach may be taken where the RIS is configured to use different weights to reflect different reference signals, enabling a receiving device to identify the reflected signal. This can be utilized on signals used for positioning of the mobile device. Additionally or alternatively, this can be used for positioning of the RIS.

Abstract: Certain aspects of the present disclosure provide techniques for allocating channel state information (CSI) processing unit (CPU) for user equipment (UE) initiated CSI. For example, the UE may receive an indication from a network entity (e.g., a base station or gNB) configuring the UE with a number of one or more CPUs allowed to be occupied for UE-initiated CSI feedback. The UE uses the at least one of the CPUs to calculate UE-initiated CSI feedback. The UE transmits at least one report including the UE-initiated CSI feedback if one or more conditions are met, such as when a mismatch between a CSI metric for a scheduled physical downlink shared channel (PDSCH) and a CSI metric calculated as part of the UE-initiated CSI feedback is equal to or exceeding a threshold value.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for indicating or switching among or between different precoding types for one or more communication elements. The one or more communication elements may be antennas of a wireless communication device (e.g., a UE or a BS) or elements of a reconfigurable intelligent surface (RIS). Techniques herein relate to indicating to one or more devices which precoding type to use for precoding one or more communication elements. For example, the techniques herein may be used for precoding communication elements of any suitable wireless communication device, such as antennas of a UE or BS, or RIS elements of a RIS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) associated with a first numerology. The UE may receive, from a base station and based at least in part on the SSB associated with the first numerology, information identifying time domain and frequency domain locations of one or more SSBs associated with a second numerology. Numerous other aspects are described.
