论文摘要
半偏见（半GF）非正交多访问（NOMA）启用赠款（GF）和基于赠款（GB）的用户共享相同的资源块，从而平衡了通信的连接性和稳定性。这封信分析了半GF NOMA系统的奇异率。首先，本文利用了一个被表示为动态协议的半GF协议，用于通过GB用户的瞬时收到的功率将GF用户选择进入被占用的GB频道。在此协议下，得出了沿着沿阵行率的封闭形式的分析和近似表达式。数值结果表明，GF用户（弱NOMA用户）具有性能上限，而GB用户（强NOMA用户）的Ergodic速率与发射信号噪声比率相比增加了。
Semi-grant-free (Semi-GF) non-orthogonal multiple access (NOMA) enables grant-free (GF) and grant-based (GB) users to share the same resource blocks, thereby balancing the connectivity and stability of communications. This letter analyzes ergodic rates of Semi-GF NOMA systems. First, this paper exploits a Semi-GF protocol, denoted as dynamic protocol, for selecting GF users into the occupied GB channels via the GB user's instantaneous received power. Under this protocol, the closed-form analytical and approximated expressions for ergodic rates are derived. The numerical results illustrate that the GF user (weak NOMA user) has a performance upper limit, while the ergodic rate of the GB user (strong NOMA user) increases linearly versus the transmit signal-to-noise ratio.
