Abstract
Methods and apparatus for efficiently implementing a rake receiver which allows for rake receiver elements, e.g., fingers, to be dynamically assigned to antenna elements are described. In at least some embodiments multiple antennas are used. Rake elements are allocated to antennas in a dynamic manner with sets of weights also being assigned dynamically, e.g., based on channel estimates. Rake finger assignment to antenna's is made, in some embodiments, to maximize signal recovery taking into consideration the channel conditions detected by each antenna for the various delays that may be supported. Through the dynamic assignment of rake finger's to antenna's, a single rake finger may be coupled to different antennas at different times allowing for more efficient use as compared to systems where rake fingers are dedicated on a fixed basis to an individual antenna.
