提出了一种新的随机接入媒体接入控制（MAC）协议，即全双工多包接收媒体接入控制（FM-MAC）协议，它结合了带内全双工（FDX）和多包接收（MPR）技术。该协议旨在通过结合FDX加倍潜力和MPR能力来最大限度地提高频谱效率，以处理并发传输造成的干扰。一个跨层的方法如下：FM-MAC选择传输模式，并定义传输功率，以最大限度地提高吞吐量，保证最小的带宽为移动的终端（MT），不能使用FDX。使用具有10个MT的模拟来评估性能，该模拟研究了FDX和半双工（HDX）MT的不同组合中的负载的影响。结果表明，在系统不进入饱和状态的前提下，用FDX替换HDX MT，吞吐量提高了33%，延迟降低了。
This paper proposes a new random access Medium Access Control (MAC) protocol, named as Full-duplex Multipacket reception Medium Access Control (FM-MAC), which jointly uses In-band Full-Duplex (FDX) and MultiPacket Reception (MPR) techniques. The protocol was designed to maximize the spectral efficiency by combining the FDX doubling potential and the MPR capability to handle interference due to concurrent transmissions. A cross-layer approach was followed: FM-MAC selects the transmission mode and defines the transmission power to maximize throughput, guaranteeing a minimal bandwidth for mobile terminals (MTs) that cannot use FDX. The performance was evaluated using simulations with 10 MTs, which studied the influence of the load in different combinations of FDX and half-duplex (HDX) MTs. The results show that replacing HDX MTs for FDX increases the throughput 33% and reduces the delay, as long as, the system does not enter into saturation.
