Abstract:
1. An apparatus for use in a communication system, the apparatus comprising: a receiver, including a plurality of receiver chains adapted for processing in the receiver, for receiving a pilot channel and determining a channel condition of said pilot channel; and a control system for controlling receive diversity and power consumption of said receiver by selecting a number of said plurality of receiver chains based on said determined channel condition; wherein: said control system is configured for reducing said number of selected receiver chains when said determined channel condition is above a first channel condition threshold, said control system is configured for increasing said number of selected receiver chains when said determined channel condition is below a second channel condition threshold, said first channel condition threshold corresponds to a stronger channel condition than a channel condition corresponding to said second channel condition threshold, and said control system is configured for adjusting a delta threshold corresponding to a difference between said first and second channel condition thresholds based on a mobility level of said receiver in said communication system.
