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, a channel state information (CSI) report configuration including configuration information that identifies a channel measurement resource associated with a first numerology and configuration information that identifies an interference measurement resource associated with a second numerology that is different from the first numerology. The UE may perform a channel measurement on the channel measurement resource associated with the first numerology and an interference measurement on the interference measurement resource associated with the second numerology. The UE may transmit, to the base station, a CSI report based at least in part on the channel measurement and the interference measurement. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, information that indicates a periodic sequence of network energy saving (NES) states that are each associated with an antenna configuration of the network node. The UE may receive, from the network node during a current time period, one or more downlink transmissions using a maximum quantity of multiple input multiple output (MIMO) layers associated with an active NES state that is identified for a current time period based at least in part on the periodic sequence of NES states. Additionally or alternatively, the UE may transmit, to the network node during the current time period, one or more sounding reference signal (SRS) transmissions using an SRS antenna sounding configuration associated with the active NES state for the current time period. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques support decoupled uplink and downlink communications via reconfigurable intelligent surfaces. Generally, the described techniques provide for using different passive network nodes for uplink and downlink communications. A user equipment (UE) may receive, from a base station, an indication of a first transmission configuration indicator state for downlink communications with the base station and a second transmission configuration indicator state for uplink communications with the base station. The UE may receive, from the base station via a first passive device (e.g., a first reconfigurable intelligent surface (RIS)) associated with the first transmission configuration indicator state, a downlink message in a radio frame. The UE may transmit, to the base station via a second passive device (e.g., a second RIS) associated with the second transmission configuration indicator state, an uplink message in the radio frame.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive, from a base station, an indication of a degree of UE loading for at least one of a set of reconfigurable reflective surfaces that are configured to assist in communications between the UE and the base station. The UE may select a reconfigurable reflective surface for use in the communications between the UE and the base station based on the degree of UE loading of the selected reconfigurable reflective surface, and transmit a signal to the base station via the selected reconfigurable reflective surface. In some cases, the UE may receive, from the base station, an indication for the UE to use a different reconfigurable reflective surface than the selected reconfigurable reflective surface, and may transmit a second signal to the base station via a second reconfigurable reflective surface based on the indication.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a method for reconfigurable intelligent surface (RIS)-assisted sensing performed by a base station (BS) includes configuring one or more reciprocal RIS beam pairs for sensing, wherein each of the one or more reciprocal RIS beam pairs comprises a downlink (DL) beam having a DL angle of departure (DL AoD) from a RIS controlled by a first set of control voltages and an uplink (UL) beam having an UL AoD from the RIS controlled by a second set of control voltages. The BS may send, to the RIS, information identifying the one or more reciprocal RIS beam pairs. The BS may perform monostatic sensing using at least one of the one or more reciprocal RIS beam pairs.
