Title
(EN) METHOD AND APPARATUS FOR RANDOM ACCESS PREAMBLE DETECTION
Abstract
(EN) Embodiments of the present disclosure provide a method in a base station for random access preamble detection. The method comprises determining a frequency offset of a received uplink signal and adjusting the received uplink signal with the determined frequency offset. The method also comprises detecting from the adjusted uplink signal whether there is a random access preamble with a first false alarm value. Additionally the method may further comprise detecting from the received uplink signal whether there is a random access preamble with a second false alarm value before determining the frequency offset of the received uplink signal. Determining the frequency offset of the received uplink signal may be performed in response that a random access preamble is detected with the second false alarm value the second false alarm value being higher than the first false alarm value. Embodiments of the present disclosure also relate to a corresponding apparatus and a base station using the method.
