Joint Power Allocation for a Novel Positioning-communication Integrated Signal

This paper develops a positioning-communication joint power allocation method for a novel positioning-communication integrated signal called Multi-Scale Non-Orthogonal Multiple Access (MS-NOMA). One of the main differences between the MS-NOMA and the traditional positioning signal is MS-NOMA supports configurable powers for different positioning users (P-Users) to obtain better ranging accuracy and signal coverage. In this paper, the proposed joint power allocation method minimizes the average range measurement error of all P-Users in the network. Meanwhile, it guarantees QoS (Quality of Services) requirements, which BER (Bit Error Rate) is selected to evaluate, and total transmit power budget of all users, including P-Users and communication users (C-Users). The numerical results show the effectiveness of the proposed joint power allocation method.
