A user equipment (UE), in general, has access to multiple radio access technologies (RATS). Besides primary base stations, secondary base stations can also aid the UE’s communication. Thus data can reach the UE via multiple secondary base stations. Taking advantage of the benefits of using such multiple paths, we propose in this paper a soft combining scheme that improves block error rate (BLER) and throughput. We propose data duplication and integration at the Physical layer of layer 1 for downlink operations of 4G LTE, 5G NR, and WLAN. At the Physical layer of ENodeB (gnodeB), the data above the Physical layer is duplicated and sent to the UE via various paths. All these PDUs have the same sequence number (SN). Data from various networks are then linked together using the assigned SN at EnodeB to obtain an enhanced version of the PDU at UE. Although this technique involves new procedures when aggregating data at the Physical layer, the average delay for a Physical-based aggregation scheme is very small compared with the conventional method because of the significant improvement in the block error rate (BLER) provided by the scheme over the BLER of the traditional standalone system. Finally, the BLER improvement results in throughput enhancement.
