System and method for coordinating multiple wireless communications devices in a wireless communications network

A wireless communications network including:

• a coordinating wireless communications device;
• and
• a plurality of wireless communications devices, coordinated by the coordinating wireless communications device;
• wherein:
• the coordinating wireless communications device obtains a plurality of supported narrow-band channels in the wireless communications network;
• the coordinating wireless communications device selects a primary channel from the supported narrow-band channels and using the primary channel to communicate with the plurality of wireless communications devices;
• the coordinating wireless communications device organizes the plurality of wireless communications devices into one or more communication groups;
• and
• the coordinating wireless communications device assigns one of the one or more communication groups a non-overlapping operating channel for multi-user down-link multiple-input multiple-output (MU DL MIMO) operation with the coordinating wireless communications device, wherein the non-overlapping operating channel contains at least two of the plurality of supported narrow-band channels in a coalesced manner in frequency domain;
• and
• the coordinating wireless communications device assigns another one of the one or more communication groups another non-overlapping operating channel for multi-user up-link multiple-input multiple-output (MU UL MIMO) operation with the coordinating wireless communications device, wherein the another non-overlapping operating channel contains at least two of the plurality of supported narrow-band channels in a coalesced manner in the frequency domain,
• wherein communication on the non-overlapping operating channel for the MU DL MIMO operation and communication on the another non-overlapping operating channel for the MU UL MIMO operation are concurrent, wherein the bandwidth of each of the non-overlapping operating channel and the another non-overlapping operating channel is determined based on at least one parameter selected from a group comprising the availability of the number of the supported narrow-band channels, the level of the interference of each supported narrow-band channel, and the respective supported narrow-band channels supported by each of the wireless communications device, and the bandwidth of at least one of the non-overlapping operating channel and the another non-overlapping operating channel is less than a sum of the bandwidths of the plurality of supported narrow-band channels.
