Method and system for evaluating a wireless link
First Claim
1. A method for evaluating a wireless link between a transmitter and a first receiver in a multiple access wireless communications system, wherein said transmitter is transmitting information intended for a first receiver in a first transmission mode and information intended for said second receiver in a second transmission mode that is different from said first transmission mode, comprising:
- receiving, at said first receiver, said information that is intended for said second receiver and that is transmitted in said second transmission mode;
obtaining, at said first receiver, an error measure for said information that is received at said first receiver and intended for said second receiver; and
determining if said second transmission mode is an acceptable transmission mode at least in part based on said error measure obtained for said information that is received at said first receiver and intended for said second receiver.

Abstract
A wireless link between a first transmitter and a first receiver in a multiple access communications system is evaluated by receiving, at the first transmitter, information that is intended for a second receiver and that is transmitted in a second transmission mode that is different from the current transmission mode and obtaining an error measure for the information that is received at the first receiver and intended for the second receiver. The obtained error measure is then used to determine if the second transmission mode is an acceptable transmission mode. In an embodiment, if the second transmission mode is determined to be acceptable, then the current transmission mode of the first receiver can be replaced by the second transmission mode. In an embodiment, the current transmission mode is replaced by the second transmission mode only if the second transmission mode is a “higher” transmission mode than the current transmission.

-
a transmitter;
a first receiver;
a second receiver;
said transmitter including means for transmitting frames of information intended for said first receiver in a first transmission mode and for transmitting frames of information intended for said second receiver in a second transmission mode that is different from said first transmission mode;
said first receiver including;
