    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying a set of sub-bands for receiving, via a set of reconfigurable intelligent surfaces (RISs), a signal. The UE may receive, via a first RIS of the set of RISs, the signal in a first sub-band of the set of sub-bands. The UE may receive, via a second RIS of the set of RISs, the signal in a second sub-band of the set of sub-bands. The UE may transmit, based at least in part on receiving the signal, RIS information indicating at least one of: first RIS information regarding the first RIS, or second RIS information regarding the second RIS. Numerous other aspects are described.

    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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to transmit, to a base station via a reconfigurable surface at a first transmission occasion, a first reference signal associated with a first reflection matrix configuration used by the reconfigurable surface to reflect signals, the first reflection matrix configuration included within a set of reflection matrix configurations. The UE may then transmit, to the base station via the reconfigurable surface at a second transmission occasion, a second reference signal associated with a second reflection matrix configuration used by the reconfigurable surface to reflect signals, the second reflection matrix configuration included within the set of reflection matrix configurations. The may then communicate with the base station via the reconfigurable surface based on transmitting the first reference signal, the second reference signal, or both.

    Abstract: An apparatus for wireless communication is provided. The apparatus may be a network node. The apparatus receives a set of uplink transmissions from a set of user equipments (UEs) via a first resource of a non-orthogonal channel, wherein the apparatus is unable to decode the set of uplink transmissions. The apparatus transmits a retransmission request to a subset of the set of UEs. The apparatus receives a retransmission of a first uplink transmission in the set of uplink transmissions via a second resource of the non-orthogonal channel in response to the retransmission request. The apparatus decodes a second uplink transmission in the set of uplink transmissions based on at least the retransmission of the first uplink transmission.
