Mesh topology for sub-thz deployment

An apparatus for wireless communication at a network entity, comprising:

• a memory;
• and
• at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
• establish a first communication with a user equipment (UE) and a first sub-Terahertz (THz) repeater on a primary cell;
• receive, from the first sub-THz repeater via the primary cell, a capability indication related to a sub-THz band;
• transmit an activation for a sub-THz communication for the UE, the sub-THz communication being on a first frequency range that does not include a second frequency of the first communication;
• transmit, for the first sub-THz repeater based on the capability indication via the primary cell, the activation for the sub-THz communication and at least one configuration of a synchronization and beam management session for the first sub-THz repeater;
• communicate, via the primary cell, scheduling information for at least one data channel transmission over the sub-THz band for the UE;
• and
• communicate, via the first sub-THz repeater and the sub-THz communication, the at least one data channel transmission for the UE.
