Abstract
A method for dynamically adjusting the revisit rate of a rake receiver for an individual UE is disclosed, such that the time to initially acquire the UL transmission is optimized while the ongoing Central Processing Unit (CPU) loading during normal operation is minimized. The method may comprise operating a multipath searcher in a first mode of operation at a first time, the first mode being an acquisition mode, the multipath searcher operating with a revisit rate of 100 percent; and, operating the multipath searcher in a second mode of operation at a second time, the second mode being a steady-state mode and the multipath searcher operating with a revisit rate of less than 100 percent.
Claims9
A method for operating a rake receiver in a code division multiple access (CDMA) radio transceiver, comprising:
- operating a multipath searcher in a first mode of operation at a first time, wherein the first mode is an acquisition mode wherein the multipath searcher operates with a revisit rate of 100 percent;
- and,
- operating the multipath searcher in a second mode of operation at a second time, wherein the second mode is a steady-state mode wherein the multipath searcher operates with a revisit rate of less than 100 percent.
