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 configuration of a beam report associated with a set of base station transmit beams, the set of base station transmit beams being directed to the UE via a backscatter link reflected by a backscatter device. The UE may transmit, to the base station, the beam report based at least in part on the configuration of the beam report, the beam report corresponding to the backscatter link. Numerous other aspects are described.

An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive, from a base station, a configuration of a beam report associated with a set of base station transmit beams, the set of base station transmit beams being directed to the UE via a backscatter link reflected by a backscatter device;
- and
- transmit, to the base station, the beam report based at least in part on the configuration of the beam report, the beam report corresponding to the backscatter link.
An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive, from a base station, a configuration of an uplink transmission, wherein the UE is in wireless communication with the base station via a direct link and via a backscatter link reflected by a backscatter device;
- and
- transmit, to the base station and based at least in part on the configuration, the uplink transmission via the direct link and via the backscatter link during a period of mandatory reflection associated with the backscatter device.
