Document Type and Number:
WIPO Patent Application WO/2010/075701
Kind Code:
A1
Abstract:
The present invention discloses a method and a system for random access, wherein, the method includes: network side sending the special random access preamble index of a terminal to the terminal; the terminal sending the random access request to the network side according to the received special random access preamble index; the network side allocating the Physical Uplink Common Control Channel (PUCCH) resource and Sounding Reference Signal (SRS) resource to the terminal according to the random access request, and sending the allocated PUCCH resource and SRS resource to the terminal. By means of the technical solution of the present invention, the problem of taking long time for the synchronization recovery process between User Equipment (UE) and network side is solved, and the delay of the data transmission is shortened, the requirement for the hardware of the network side is decreased, and the experience of users is improved.
