Optimizing Information Freshness via Multiuser Scheduling With Adaptive NOMA/OMA
IEEE Transactions on Wireless Communications(2022)
摘要
This paper considers a wireless network with a base station (BS) conducting timely status updates to multiple clients via adaptive non-orthogonal multiple access (NOMA)/orthogonal multiple access (OMA). Specifically, the BS is able to adaptively switch between NOMA and OMA for the downlink transmission to optimize the information freshness of the network, characterized by the Age of Information (A...
