    Abstract: PURPOSE: A device and a method for transmitting a random access preamble are provided to acquire excellent frequency diversity by distributing PACH(Random Access CHannel) backup resources at the both ends of a frequency band. CONSTITUTION: Firstly, UE(User Equipment) receives signal from a BS(Base Station) through a transmitting/receiving unit(504). The received signal is de-multiplexed through a physical channel de-multiplexer(503) and broadcast information(501) on RACH configuration and SRS configuration information(502) are obtained; Then, if it is necessary to transmit the random access preamble, UE selects its occupied RACH resources from the plurality of continuous ones at one end of the system frequency band according to currently configured RACH resource configuration pattern. Now, the random access preamble is generated in a random access preamble generator(506). After multiplexed by a physical channel multiplexer(505) into the selected RACH resources, the preamble is transmitted through the transmitting/receiving unit. In the case that BS configures the frequencies other than those for RACH resources to be transmit SRS, UE generates STS in an SRS generator(507), multiplexes it into the BS's configured frequencies through the physical channel multiplexer, and then transmits it through the transmitting/receiving unit.

    Abstract translation: 目的：提供一种用于发送随机接入前同步码的装置和方法，以通过在频带的两端分配PACH（随机接入信道）备份资源来获得优异的频率分集。 构成：首先，UE（用户设备）通过发送/接收单元（504）从BS（基站）接收信号。 接收到的信号通过物理信道解复用器（503）解复用，获得关于RACH配置和SRS配置信息（502）的广播信息（501） 然后，如果需要发送随机接入前导码，则UE根据当前配置的RACH资源配置模式，在系统频带的一端从多个连续的RACH资源中选择其占用的RACH资源。 现在，在随机接入前导码生成器（506）中生成随机接入前同步码。 在通过物理信道多路复用器（505）复用到所选择的RACH资源之后，通过发送/接收单元发送前导码。 在BS配置不同于RACH资源发送SRS的频率的情况下，UE在SRS发生器（507）中生成STS，通过物理信道多路复用器将其复用到BS的配置频率中，然后通过发送 /接收单元。
