Abstract
Methods and apparatus in a multi-carrier cellular wireless network (303, 304, 305, 320) with random access improve receiving reliability and reduce interference of uplink signals of a random access, while improving the detection performance of a base station receiver (310, 320) by employing specifically configured ranging signals.
