1. A method comprising:
- dynamically assigning, to a receiving device, an available time slot in a first frequency channel of a broadcast communication signal including a plurality of frequency channels;
associating a unique ID with a first data packet to thereby identify the receiving device for the first data packet;
receiving information identifying a link condition for the receiving device;
dynamically assigning a modulation and coding format for the first data packet to account for the identified link condition;
generating a frame including;
a slot including a first field specifying the modulation and coding format and a second field identifying a next time slot in a subsequent frame for the receiving device to receive a subsequent data packet, wherein the subsequent frame may specify a new modulation and coding format for the receiving device; and
one or more additional slots including the first data packet and a second set of data packets destined for other users; and
transmitting the frame to the receiving device, wherein the first data packet is transmitted within the frame according to the modulation and coding format in the dynamically assigned time slot of the first frequency channel.

Abstract
An architecture for the dynamic assignment of links in a multi-user communication system. A plurality of information channels are provided in a forward communication link of the communication system for carrying channel information of the plurality of information channels from a transmitter to a plurality of corresponding receiving devices. The channel information in corresponding select ones of the plurality of information channels is varied dynamically in response to link conditions of the associated receiving devices to more efficiently utilize the channel bandwidth.
