Method of data rate adaptation for multicast communication
First Claim
Patent Images
1. A method comprising:
- transmitting multicast data frames at a first data rate;
receiving a number of acknowledgments of successful frame reception using the first data rate;
increasing the first data rate to a second data rate for a period of time in response to the number of acknowledgements;
transmitting multicast data frames at the second data rate;
determining frame loss during the period of time; and
determining a third multicast data rate responsive to the multicast frame loss, wherein the step of determining a third multicast data rate responsive to the multicast frame loss comprises using the second data rate as a new multicast data rate if the frame loss is less than a threshold, and wherein the threshold is a probability threshold based upon a ratio of transmission times of the second data rate and the first data rate.

Abstract
A method to implement an adaptive multicast data rate transmission selection includes determining the lowest signal strength station in a multicast group, using signal strength as an indicator to increase data rate, and determining if the increase in data rate is viable for multicast transmission by determining frame or packet loss using the increased data rate.
