METHOD, SYSTEM AND APPARATUS FOR MULTICAST DATA RATE SELECTION
First Claim
1. A method of multicast data rate selection in an access point, the method comprising:
- establishing respective connections between the access point and a plurality of client devices;
determining whether to set a legacy client presence flag in a memory of the access point based on whether the plurality of client devices includes a legacy client device;
prior to initiating a multicast transmission to the plurality of client devices, determining whether the legacy client presence flag is set;
when the legacy client presence flag is set, setting a selected multicast data rate corresponding to a first maximum data rate in a subset of legacy-compatible data rates stored in the memory; and
when the legacy client presence flag is not set, setting the selected multicast data rate corresponding to a second maximum data rate in a subset of non-legacy-compatible data rates stored in the memory.

Abstract
A method of multicast data rate selection in an access point includes: establishing respective connections between the access point and a plurality of client devices; determining whether to set a legacy client presence flag in a memory of the access point based on whether the plurality of client devices includes or does not include a legacy client device; prior to initiating a multicast transmission to the plurality of client devices, determining whether the legacy client presence flag is set; when the legacy client presence flag is set, setting a selected multicast data rate corresponding to a first maximum data rate in a subset of legacy-compatible data rates stored in the memory; and when the legacy client presence flag is not set, setting the selected multicast data rate corresponding to a second maximum data rate in a subset of non-legacy-compatible data rates stored in the memory.

11. An access point device, comprising:
-
a communications interface; a memory; and a connection manager configured to establish respective connections with a plurality of client devices via the communications interface; a legacy client monitor configured to determine whether to set a legacy client presence flag in the memory based on whether the plurality of client devices includes a legacy client device; a data rate selector configured to; prior to initiating a multicast transmission to the plurality of client devices, determine whether the legacy client presence flag is set; when the legacy client presence flag is set, set a selected multicast data rate corresponding to a first maximum data rate in a subset of legacy-compatible data rates stored in the memory; and when the legacy client presence flag is not set, set the selected multicast data rate corresponding to a second maximum data rate in a subset of non-legacy-compatible data rates stored in the memory. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
