Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform single frequency network (SFN) manner relaying in sidelink to support exchanging packets between UEs, for example, without maintaining beamforming alignment between the UEs. A first UE (e.g., a source UE or destination UE) may establish a pre-agreement with a second UE for the second UE to operate as an SFN-manner relay over sidelink for the first UE. The pre-agreement may be reached via a publish-and-subscription procedure, in which the second UE publishes an SFN-type relaying service and the first UE subscribes to the SFN-type relaying service. The second UE may receive sidelink signaling associated with the first UE (e.g., transmitted by or to the first UE) and may relay the sidelink signaling in a resource configured for SFN-type transmission based on the first UE being subscribed to the SFN-type relaying service.
