This disclosure describes systems, devices, and computer-implemented methods that facilitate the simultaneous transmission of subsets of user plane data to a telecommunications network via two or more uplink transmission paths. More specifically, a mobile device may detect user plane data within a buffer pool and in doing so, transmit a resource allocation request for the uplink transmission of the user plane data. In response, the mobile device may receive a set of control plane data associated with the uplink transmission via two or more uplink transmission paths. The mobile device may simultaneously transmit subsets of user plane data to the telecommunications network via multiple base station nodes, based at least in part on the control plane data.
