PHASE CONTINUITY ASSOCIATED WITH RECONFIGURABLE INTELLIGENT SURFACES

Abstract

Methods, systems, and devices for wireless communications are described. A reconfigurable intelligent surface (RIS) may indicate an ability to maintain phase continuity across transmissions. The RIS may transmit a capability information message and receive control signaling indicating one or more conditions under which the RIS may maintain phase continuity. For example, the RIS may maintain phase continuity when the separation time between consecutive transmissions may be long enough for the RIS to change to an original configuration or original set of transmission parameters. In other cases, the RIS may maintain phase continuity when the same configuration or set of transmission parameters are used between consecutive transmissions, and the time between the transmissions does not exceed a threshold. The RIS may relay signals based on the one or more conditions.
