Methods and apparatus for random access in multi-carrier communication systems
Methods and apparatus in a multi-carrier cellular wireless network with random access improve receiving reliability and reduce interference of uplink orthogonal frequency division multiplex (OFDM) signals of a random access, while improving the detection performance of a base station receiver by employing specifically configured ranging signals. The OFDM signals of the random access are transmitted in a at least one block indicated in configuration information. Uplink signals are transmitted with a timing adjusted based on a received time advance and a power adjusted based on a received power adjustment.
