METHOD AND APPARATUS FOR IMPROVING RANDOM ACCESS PREAMBLE TRANSMISSION IN A WIRELESS COMMUNICATION SYSTEM

摘要

Methods and apparatuses are disclosed for improving Random Access preamble transmission in a wireless communication system. The method includes receiving a configuration of an initial power and a power ramping step for a preamble transmission. The method also includes transmitting a first Preamble using a first power based on at least the initial power and the power ramping step, wherein the first Preamble is the last preamble transmission of a first Random Access procedure. The method includes determining whether the first Random Access procedure is successfully completed. The method also includes transmitting a second Preamble using a second power based on at least the first power, wherein the second Preamble is the first preamble transmission of a second Random Access procedure.
