Design and Evaluation of Buffer-Aided Cooperative NOMA with Direct Transmission in IoT
IEEE Internet of Things Journal(2021)
摘要
The high spectrum efficiency of nonorthogonal multiple access (NOMA) is attractive to solve the massive number of connections in the Internet of Things (IoT). This article investigates a buffer-aided cooperative NOMA (C-NOMA) system in the IoT, where the intended users are equipped with buffers for cooperation. The direct transmission from the access point to the users and the buffer-aided coopera...
