1. A method for determining a position of a remote terminal in a communication system, the method comprising:

  • identifying a first set of one or more base stations in active communication with the remote terminal;

    assigning at least one finger processor of a rake receiver to each base station in the first set;

    identifying a second set of one or more base stations not in active communication with the remote terminal;

    assigning an available finger processor to at least one base station in the second set;

    performing a time measurement for each base station assigned with at least one finger processor;

    wherein the performing includes processing a multipath for the base station to obtain samples, and processing the samples to determine a start of a radio frame for a particular transmission, and wherein the time measurement is indicative of the start of the radio frame, and providing outputs indicative of time measurements obtained for base stations assigned with finger processors.
