这封信的目的是开发一种新的认知无线电启发的非正交多址接入（CR-NOMA）设计，它确保可以支持多个新用户，而不会对传统网络造成中断。分析结果的特点，支持新用户的数量的统计特性。所提出的CR-NOMA方案由于可以作为一个简单的附加设备实现，因此可以兼容各种通信网络，并给出了在时分多址网络中使用CR-NOMA作为一个附加设备来减少信息年龄的一个例子。
The aim of this letter is to develop a new design of cognitive radio inspired non-orthogonal multiple access (CR-NOMA), which ensures that multiple new users can be supported without causing disruption to the legacy network. Analytical results are developed to characterize the statistical properties of the number of supported new users. The developed CR-NOMA scheme is compatible to various communication networks, because it can be implemented as a simple add-on. An example of using CR-NOMA as an add-on in time-division multiple access networks for age of information reduction is illustrated.
