Abstract In a wireless self-organizing and the network-assisted Device-to-Device (D2D) network, proximal Device Discovery (DD) plays a noteworthy role. It is the foundation for self-governing, coverage expansion and performance improvement for example, cooperative and multi-hop transmission. Energy efficiency and discovery accuracy are critical performance measures for proximal DD. A novel DD procedure using Non-orthogonal Multiple Access based Multi-user Shared Access (MUSA) is proposed in this article for network-assisted D2D communication. The proposed shared access scheme uses a complex spreading pattern to accommodate dense device discovery and enhance discovery distance in the cellular systems. A discovery signal shared access method with supplementary schemes for multi-user detection is also designed. With MUSA and its spreading pattern demodulation, 12% enhanced energy efficiency, and 98% overall improved accuracy is achieved contrasted with the customary DD methods.

1 Introduction New applications in wireless and telecommunication network request low latency, higher data rate, the better quality of service and enhanced coverage from the current wireless system setup. The wireless system performance can be enhanced by incorporating the developing technologies and innovations. One of the innovations to achieve the new application requirements is Device-to-Device (D2D) communication in which devices communicate autonomously or with the supervision of the base station [1]. In addi-

tion, the base station can be eased from substantial cellular traffic burden due to proximity services and it is a primary advantage in which devices must know their proximal companions [2,3]. Therefore, numerous physical and technical issues are experienced in accomplishment of proximity services and D2D communication, for example, Device Discovery (DD), collaboration and interference among devices, and energy utilization [4,5]. One of the basic physical and technical issues is the DD, which is used to initiate proximity services in D2D communication. A proximal DD procedure utilizes for recognizing neighbor mobile devices, which can specifically speak with one another and is a fundamental i
