阅读说明：本技术 用于非正交多址无线通信的信号扩展技术 (Signal spreading techniques for non-orthogonal multiple access wireless communications ) 是由 雷静 S·朴 N·布衫 于 2019-01-14 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,其中不同的扩展序列可被用于区分并发的非正交多址(NOMA)传输。这些扩展序列可以基于在用户设备(UE)处配置的一个或多个码本以及用于上行链路NOMA传输的码本来选择,该用于上行链路NOMA传输的码本是基于为上行链路NOMA传输分配的共用资源集以及传送方群中的预期传送方数目来确定的。该UE可标识要在上行链路NOMA传输中传送的数据,将扩展序列应用于数据,并且在上行链路NOMA传输中传送经扩展数据。基站可以接收多个并发的上行链路NOMA传输,执行接收信号处理以标识扩展信号和UE身份,基于不同的扩展序列来解扩展信号,并且解调和解码NOMA UE的经解扩展信号。(Methods, systems, and devices are described for wireless communications in which different spreading sequences may be used to distinguish concurrent non-orthogonal multiple access (NOMA) transmissions. The spreading sequences may be selected based on one or more codebooks configured at a User Equipment (UE) and a codebook for uplink NOMA transmission determined based on a set of common resources allocated for uplink NOMA transmission and an expected number of transmitters in a group of transmitters. The UE may identify data to be transmitted in an uplink NOMA transmission, apply a spreading sequence to the data, and transmit the spread data in the uplink NOMA transmission. The base station may receive multiple concurrent uplink NOMA transmissions, perform received signal processing to identify a spread signal and a UE identity, despread the signal based on different spreading sequences, and demodulate and decode the despread signal of a NOMA UE.)
