ABSTRACT:
A method and apparatus controls a plurality of receiver channel elements (102a–102n), such as RAKE receiver fingers in a CDMA receiver, by assigning a real time priority metric to each channel type. For example, a receiver channel element management module (109) generates a channel weight value (216) and a receiver channel element factor value (218). The channel weight value (216) is dynamically determined on a per channel type basis representing an extent of energy demanded by a channel. For example, a channel at a higher rate may be programmed to start off with higher energy needs as compared to a different channel type, such as a voice channel which may communicate information at a lower rate. The receiver channel element factor value (218) is used to determine an impact of deassigning receiver fingers so that the dropped receiver finger is the one that is least harmful to all channels.
