阅读说明：本技术 用于非正交多址无线通信的参考信号传输技术 (Reference signal transmission techniques for non-orthogonal multiple access wireless communications ) 是由 雷静 R·王 S·朴 N·布衫 J·K·森达拉拉扬 J·B·索里亚加 T·姬 于 2019-02-01 设计创作，主要内容包括：描述了用于无线通信的方法、系统和设备,该方法、系统和设备提供使用公用资源的来自多个非正交多址(NOMA)发射机的并发参考信号传输,诸如解调参考信号(DMRS)传输。不同发射机可以将不同的序列用于参考信号传输,这可允许接收机(诸如无线基站)解码每一个NOMA发射机的参考信号传输并且为每一个NOMA发射机执行信道估计。参考信号传输可以是具有有界定时偏移的异步的或者是准同步的,并且参考信号序列选择可以提供相对可靠的信道估计和相干解调。(Methods, systems, and devices are described for wireless communication that provide concurrent reference signal transmissions, such as demodulation reference signal (DMRS) transmissions, from multiple non-orthogonal multiple access (NOMA) transmitters using common resources. Different transmitters may use different sequences for reference signal transmission, which may allow a receiver (such as a wireless base station) to decode the reference signal transmission of each NOMA transmitter and perform channel estimation for each NOMA transmitter. Reference signal transmission may be asynchronous or quasi-synchronous with bounded timing offsets, and reference signal sequence selection may provide relatively reliable channel estimation and coherent demodulation.)
