RANDOM ACCESS METHOD OF TIME DIVISION SYNCHRONIZATION CODE DIVISION MULITPLE ACCESS ENHANCED UPLINK SYSTEM

摘要

A random access method of time division synchronization code division multiple access (TD-SCDMA) enhanced uplink system is disclosed, the method includes the following steps: the channel resources of the fast physical access channel (FPACH) and the physical random access channel (PRACH) and the enhanced random access uplink control channel (E-RUCHH) are configured on the main carrier of the TD-SCDMA enhanced uplink system, and synchronous code set is configured for the main carrier in order to indicate the general random access and the enhanced uplink random access; the uplink pilot timeslot resources are used, and the physical channel resources of FPACH and E-RUCHH are configured on the assistant carrier of the TD-SCDMA enhanced uplink system; The user device can be accessed in a transmission time interval (TTI) by adopting the general random access and/or adopting the enhanced random access.
