Embodiment Construction

[0040] The present invention provides a method for establishing UpPCH and FPACH on the auxiliary carrier frequency. The core of the present invention is: when UpPCH is established on the auxiliary carrier frequency, add the carrier frequency of UpPCH in the cell establishment request message of the multi-carrier frequency cell information.

[0041] Describe the present invention in detail below in conjunction with accompanying drawing, the processing flowchart of the specific implementation mode of the method of the present invention is as follows figure 2 shown, including the following steps:

[0042] Step 2-1: Add the carrier frequency information of the UpPCH in the cell establishment request message of the multi-carrier frequency cell.

[0043] When the UpPCH is established on the auxiliary carrier frequency, the cell establishment request message of the existing multi-carrier frequency cell needs to be modified. The carrier frequency information of the UpPCH shown in T...

Abstract

The invention discloses a building upward pilot channel and rapid physical switch-in channel method on assist carrier, which is characterized by the following: when the UpPCH of communication system is built on the assist carrier, the carrier information of UpPCH is carried in CELL SETUP REQUEST information; the carrier information of FPACH is definited according to carrier information of UpPCH; FPACH is built on the assist carrier. The UpPCH and FPACH are built on assist carrier when the multiple carrier subdistricts is built with the invention.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for configuring UpPCH (Uplink Pilot Channel) and FPACH (Fast Physical Access Channel) on an auxiliary carrier frequency. Background technique [0002] TD-SCDMA (Time Division Synchronous Code Division Multiple Access) is one of the three major standards of the third generation mobile communication. The capacity of TD-SCDMA is mainly limited by the channel code resource of the cell. In order to improve the system capacity, a multi-carrier frequency scheme is adopted in TD-SCDMA at present. That is, multiple carrier frequencies are used in one cell. The carrier frequency where the PCCPCH (Common Control Physical Channel) is located is the primary carrier frequency, and other carrier frequencies are secondary carrier frequencies. [0003] In a wireless communication system, the message flow of the process of establishing a cell on a NodeB (base station) is as follows: ...
