摘要： This disclosure describes systems, methods, and devices for signaling multiple modulation and coding schemes for a single user. A device may generate a common field of an ultra-high reliability signal (UHR-SIG) content channel field, the common field including signaling for station devices; generate a number of spatial streams (NSS) subfield of a user specific field of the UHR-SIG content channel field, the user specific field addressed to a first station device of the multiple station devices; generate a 6-bit modulation and coding scheme (MCS) subfield of the user specific field, wherein the 6-bit MCS subfield maps, based on a number of spatial streams signaled by the NSS subfield, to one or more MCSs assigned to the first station device; generate a frame including the UHR-SIG content channel field, wherein a user field of the user specific field includes at least 22 bits including the MCS subfield; and send the frame.

摘要： Geometrical closed loop line of sight (LOS) multiple-input-multiple-output (MIMO). Singular value decomposition (SVD) processing for a LOS communication channel into respective channel matrices, and appropriate processing of signals within transmitter and/or receiver communication devices operate to support very high data throughput, including approaching or converging to the Shannon limit channel capacity (e.g., bits/sec/Hz). Certain communication systems operate with multi-antenna communication devices, and sometimes, the optimal spacing between those respective antennae cannot be achieved. Appropriate processing can recover most, if not all, of any performance degradation as may be incurred by a deviation from the perfectly optimal spacing between those respective antennae. In addition, any deleterious effects of phase noise among the antennae may be mitigated by driving the antennae using a common or singular local oscillator, or tracking the communication channel (e.g., channel estimation, tracking, etc.) and updating the respective SVD channel matrices based upon such phase noise.

摘要翻译：几何闭环视距（LOS）多输入多输出（MIMO）。用于LOS通信信道到相应信道矩阵的奇异值分解（SVD）处理，以及发射机和/或接收机通信设备内的信号的适当处理，以支持非常高的数据吞吐量，包括接近或收敛于香农极限信道容量（例如，，比特/秒/ Hz）。某些通信系统与多天线通信设备一起工作，有时候无法实现这些相应天线之间的最佳间隔。适当的处理可以恢复由于偏离这些相应天线之间的完美最佳间隔而引起的任何性能下降的大部分（如果不是全部）。此外，通过使用公共或单个本地振荡器驱动天线或跟踪通信信道（例如，信道估计，跟踪等）和更新相应的SVD信道矩阵，可以减轻天线之间的相位噪声的任何有害影响基于这种相位噪声。
