Client grouping for point to multipoint communications
A communication system for point to multipoint communications by grouping client devices based on associated modes is provided. In one example implementation, point to multipoint communication improvements are achieved by grouping a plurality of client devices by their optimal modes for communication. For example, the communication system can determine, based on channel quality indicators (CQIs) that two client devices of a plurality of client devices are associated with an optimal first mode of a modal antenna. The system can group the two client devices into a first group, the first group associated with communication using the first mode of the modal antenna. The modal antenna can communicate with the first group using the first mode of a modal antenna during a single frame of communication.
1. A communication system for implementing a control routine comprising:
a modal antenna operable in a plurality of modes, each of the plurality of modes associated with a distinct radiation pattern;
a transceiver configured to communicate with a plurality of client devices over a wireless communication medium via the modal antenna over a plurality of frames, and
one or more control devices configured to perform operations, the operations comprising:
determining a trigger condition;
initiating a training mode based, at least in part, on the trigger condition;
generating group index data associating each client device of the plurality of client devices with one or more groups, wherein the group index data is generated based at least in part on channel quality indicators obtained while operating the communication system in the training mode; and
storing the group index data in one or more memory devices.
2. The communication system of claim 1 , wherein the trigger condition is associated with startup or setup of the communication system.
3. The communication system of claim 1 , wherein the trigger condition is associated with a manual request to enter the training mode.
4. The communication system of claim 1 , wherein the trigger condition is associated with changes of the one or more channel quality indicators associated with communicating to a particular group of client devices by a threshold amount.
5. The communication system of claim 1 , wherein the training mode is an interframe training mode, the interframe training mode associated with a plurality of frames.
6. The communication system of claim 5 , wherein the interframe training mode is implemented in one or more receive frames for a client device.
7. The communication system of claim 1 , wherein the training mode is an intraframe training mode, the intraframe training mode is associated with a first frame, the first frame comprises at least one of a preamble or a channel estimation.

configuring the modal antenna in the plurality of modes; and
selecting one of the plurality of mode based on the group index data.
9. A method for implementing a control routine in a communication system, the method comprising:
determining a trigger condition;
initiating a training mode based, at least in part, on the trigger condition;
generating group index data associating each client device of a plurality of client devices with one or more groups, wherein the group index data is generated based at least in part on channel quality indicators obtained while operating the communication system in the training mode; and
storing the group index data in one or more memory devices.
10. The method of claim 9 , wherein the trigger condition is associated with startup or setup of the communication system.
11. The method of claim 9 , wherein the trigger condition is associated with a manual request to enter the training mode.
12. The method of claim 9 , wherein the trigger condition is associated with changes of the one or more channel quality indicators associated with communicating to a particular group of client devices by a threshold amount.
13. The method of claim 9 , wherein the training mode is an interframe training mode, the interframe training mode associated with a plurality of frames.
14. The method of claim 13 , wherein the interframe training mode is implemented in one or more receive frames for a client device.
15. The method of claim 9 , wherein the training mode is an intraframe training mode, the intraframe training mode is associated with a first frame, the first frame comprises at least one of a preamble or a channel estimation.
16. The communication system of claim 15 further comprising:
configuring the modal antenna in the plurality of modes; and
selecting one of the plurality of mode based on the group index data.
