ABSTRACT:
Method and apparatus are provided for the determination of the downlink quality of a channel between a base station and a mobile station. The methods and apparatus involve the use of existing system measurements, system parameters and mobile station measurements, thereby ensuring backward compatibility with existing mobile stations. The methods and apparatus can also be employed for the determination of the downlink channel quality for a mobile station which has established radio links with one or more base stations while the mobile station is performing soft handover.
