Abstract: A system for reflecting an RF signal comprises a plurality of antenna units configured to receive the RF signal and passively reflect the RF signal. The antenna units are reconfigurable to achieve beamforming in reception and reflection, respectively, of the RF signal. The system may be a Large Intelligent Surface (LIS). A control system is configured to: detect (301) a wake-up signal WUS1, and after detecting WUS1, perform a first training operation (I) comprising: receiving (302), by the antenna units, a first reference signal RS1 from a first device D1 and reconfiguring (303) the antenna units based on RS1 to achieve beamforming in reception in a direction of D1. By the combination of WUS1 and the first training operation, the system may be automatically configured to achieve beamforming in relation to D1 which is thereby enabled to communicate via the system.

Abstract: A method includes receiving (402) a plurality of reference signals (301-303) at an antenna port of a communication device (101). Each reference signal (301-303) is sent using a corresponding precoder. The precoder is selected from a first set of precoders. The method further includes determining (403) a channel estimate based on the received plurality of reference signals (301-303), and selecting (404) a precoder from a second set of precoders based on the determined channel estimate. The second set of precoders comprises at least one precoder in addition to the precoders of the first set of precoders.
