A Multi-Service Oriented Multiple Access Scheme for M2M Support in Future LTE

Abstract : We propose a novel multiple access technique to overcome the shortcomings of the current proposals for the future releases of LTE. We provide a unified radio access system that efficiently and flexibly integrates both traditional cellular services and M2M connections arising from IoT applications. The proposed solution, referred to as MOMA, is based on establishing separate classes of users using relevant criteria that go beyond the simple handheld-IoT device split; service-dependent hierarchical spreading of the data signals; and a mix of multiuser and single-user detection schemes at the receiver. Signal spreading in MOMA allows densely connected devices with different QoS profiles to be handled, and at the same time its flexible receiver structure allows the receiver computational resources to be allocated to the connections that need them most. This yields scalable and efficient use of the available radio resources and better service integration. While providing significant advantages for key future communications scenarios, MOMA can be incorporated into LTE with a limited impact on the protocol structure and the signaling overhead. © 2017 IEEE.
