Abstract: A random access method in a mobile communication system, the random access method for supporting random access with a cell size of about 100 kilometers (km) or more and a power limited terminal and a preamble structure thereof are provided. While a conventional long term evolution (LTE) random access preamble sequence is reused, a difference in a round-trip delay time between terminals in a large cell area may be compensated. Additionally, since higher power transmission is achieved per bandwidth, a higher link margin may be secured. Also, compatibility with resource scheduling of the conventional LTE may be maintained. Random access may be supported in a large cell, and a preamble structure of a satellite mobile communication may be implemented based on terrestrial LTE.
Abstract translation: 提供了一种移动通信系统中的随机接入方法，提供了用于支持大约100千米（km）以上的小区大小的随机接入的随机接入方法和功率限制终端及其前导码结构。 虽然传统的长期演进（LTE）随机接入前导码序列被重用，但可以补偿大小区域中的终端之间的往返延迟时间的差异。 此外，由于每个带宽实现更高的功率传输，所以可以确保更高的链路余量。 此外，可以保持与常规LTE的资源调度的兼容性。 可以在大小区中支持随机接入，并且可以基于地面LTE来实现卫星移动通信的前导码结构。
