Signalling methods for a network with reconfigurable intelligent surface and repeaters

A method of communication in a cellular network, the method comprising:

• establishing, by at least one first node, a connection with at least one second node;
• transmitting, by the at least one first node, control information to the at least one second node, wherein the control information comprises a beamforming information and at least one first time resource where the control information is to be applied,
• wherein transmitting the control information is using at least one of a dedicated channel and a shared channel,
• wherein transmitting is in at least one of:
• time-frequency resources in at least one of a guard symbol and a guard band of a channel used for communication between the at least one first node and at least one third node, and
• time-frequency resources overlapping with the time-frequency resources used for communication between the at least one first node and the at least one third node;
• and,
• performing, by the at least one first node, at least one operation with the at least one third node through the at least one second node in the at least one first time resource,
• wherein the at least one operation comprises one of transmitting a signal to the at least one third node and receiving a signal from the at least one third node.
