Abstract:
1. A method for transmitting a ranging signal by a user equipment (UE) in a wireless communication system, the method comprising: receiving frequency partition configuration information from a base station (BS); determining a ranging channel (RCH) in a reuse-1 frequency partition, or in a power-boosted reuse-3 frequency partition only when there is no reuse-1 frequency partition, based on cell ID information (IDcell) of the BS and the frequency partition configuration information; and transmitting the ranging signal to the BS using the RCH, wherein the RCH is a non-synchronized ranging channel (NS-RCH) when the UE is not synchronized to the BS, and a frequency resource for the NS-RCH is determined according to Equation 1: where I where L
