An RIS-assisted communication system with K mobile users.

Caption

A multi-user MISO communication system is considered, where a BS equipped with Nt antennas serves K (K < Nt) single-antenna users. The communication is assisted by an RIS comprising of M nearly-passive reflecting elements and one RIS micro-controller. We assume that the BS and the RIS keep static and the users are moving with the same velocity.
