摘要：
Multi-user uplink communications within multiple user, multiple access, and/or MIMO wireless communication systems. Within such communication systems, uplink communications from various receiving wireless communication devices (e.g., STAs) to a transmitting wireless communication device (e.g., AP) may occur in any of a number of various dimensions or combinations thereof including MU-MIMO dimension and frequency dimension (asynchronous FDM or synchronous FDM). In accordance with such uplink communications, various considerations such as time synchronization, frequency synchronization, and/or power control (including wireless communication device grouping). When performing uplink asynchronous FDM signaling, power control as grouping is used. When performing uplink synchronous FDM signaling, time synchronization, frequency synchronization, and power control (such as including wireless communication device grouping) is performed.
