CELL SELECTION IN HIGH-SPEED DOWNLINK PACKET ACCESS COMMUNICATIONS SYSTEMS

摘要

The usual determination of signal-to-noise ratio Ec/b in a communication system is modified such that Ec/lo is also based on either or both of the path delay profile (PDP) and estimates of the load on a cell in the communication system. The PDP may be obtained from a path searcher in a receiver that is already needed for estimating the received signal code power of a channel such as a common pilot channel. Because PDP information is already available, it can easily be incorporated into the E0ZIo measurements.
