1. A base station to receive a preamble sequence from a user equipment (UE) to at least improve detection performance comprising:
a transmitter within the base station that is configured to transmit, to the UE over a broadcast channel, position information of an allocated random access channel resource, the position information including frequency information and timing information, wherein the timing information indicates a subframe; and
a receiver within the base station that is configured to receive from the UE, based on the transmitted position information, on a random access channel, a preamble sequence transmitted using at least one 1 ms duration subframe from the UE to access a cellular network, wherein the preamble sequence has the form of a single cyclic prefix (CP) concatenated to a front-end of an N-time repetition, where N is an integer greater than 1, of the product of a Zadoff-Chu Constant Amplitude Zero Auto Correlation (CAZAC) based sequence with an exponential sequence, wherein the base station is configured to use frames for communication and each of the frames is divided into 1 ms duration subframes.
