DEVICE AND METHOD FOR TRANSMITTING RANDOM ACCESS PREAMBLE

摘要

Base Station (BS) and User Equipment (UE) apparatuses for configuring a Random Access CHannel (RACH), and methods thereof, are provided. The method for a BS to configure a RACH includes generating configuration information on RACH resources, transmitting the configuration information on the RACH resources to a UE, receiving a random access preamble multiplexed on a plurality of continuous RACH resources from the UE, extracting the random access preamble multiplexed on the plurality of continuous RACH resources, and detecting the extracted random access preamble. The method for a UE to configure a RACH includes receiving configuration information on RACH resources from a BS, selecting occupied RACH resources among a plurality of continuous RACH resources, generating a random access preamble, multiplexing the generated random access preamble on the selected RACH resources, and transmitting the random access preamble on the selected RACH resources to the BS.

1. A method for transmitting a random access preamble by a terminal in a wireless communication system, the method comprising:
receiving configuration information from a base station; acquiring a physical resource block using a frequency resource index according to the configuration information; transmitting a first random access preamble using a first resource determined based on the physical resource block at one side of a system bandwidth in a first time; and transmitting a second random access preamble using a second resource determined based on the physical resource block at the other side of the system bandwidth in a second time.
