Method and apparatus for providing an efficient control channel structure in a wireless communication system
First Claim
1. A method for processing information in a communication system, comprising:
- partitioning, at an access point, a control region used for transmitting control information into a plurality of subsets of resources;
selecting, based on one or more selection criteria, a first subset of the plurality of subsets of resources within the control region to be used for transmitting the control information from the access point to a first user terminal;
selecting, based on the one or more selection criteria, a second subset of the plurality of subsets of resources within the control region to be used for transmitting the control information from the access point to a second user terminal; and
transmitting the control information in the control region from the access point, wherein the control information transmitted on the first subset of the plurality of subsets of resources is transmitted at a different code rate than the control information transmitted on the second subset of the plurality of subsets of resources.

Abstract
According to one aspect of the invention, a method is provided in which a control channel used for transmitting control information is partitioned into a plurality of subchannels each of which is operated at a specific data rate. For each of one or more user terminals, one of the subchannels is selected based on one or more selection criteria for transmitting control information from an access point to the respective user terminal. Control information is transmitted from the access point to a user terminal on a particular subchannel selected for the respective user terminal. At the user terminal, one or more subchannels are decoded to obtain control information designated for the user terminal.
