Embodiment Construction

[0060] figure 2 It is a flowchart of a method for sending scheduling information triggered by a terminal in the present invention. When high-speed packet access technology is used in a wireless communication system and data transmission is performed on dual carriers, as shown in figure 2 shown, including:

[0061] Step 200: Activating / deactivating the uplink secondary carrier.

[0062] In this step, according to the existing procedure, the serving Node B notifies the terminal to activate or deactivate the uplink secondary carrier through the HS-SCCH order. The specific implementation process of activating or deactivating the uplink secondary carrier (referred to as activation / deactivation herein) belongs to the technology known to those skilled in the art, and will not be described in detail here.

[0063] The activation / deactivation of the uplink secondary carrier in this step refers to:

[0064] When the terminal receives the HS-SCCH order to activate the uplink seconda...

Abstract

The invention provides a method and system for triggering transmission of scheduling information by a terminal. In a wireless communication system, when a high speed packet access (HSPA) technology is used for carrying out data transmission on double carriers, in uplink auxiliary carrier activation / deactivation, the terminal triggers the transmission of the scheduling information. In the invention, by the scheduling information reported by the terminal, a service node B knows the concrete resource utilization condition of the terminal and the information of a buffer area, so that the node B fully utilizes the system resources and terminal power to supply the optimal scheduling matched with the current network performance and terminal interference conditions, thereby realizing the optimal scheduling control.

Description

technical field [0001] The present invention relates to a dispatching information triggering mechanism in a wireless communication system, in particular to a method and system for a terminal to trigger dispatching information transmission when data transmission is performed on dual carriers using high-speed packet access technology in the wireless communication system. Background technique [0002] In the existing system, the scheduling information is the reference information for scheduling as the core serving Node B. The scheduling information is located at the end of the protocol data unit of the MAC entity handling the enhanced dedicated channel. The scheduling information is used to give the serving Node B a better perspective to observe the total amount of system resources required by the terminal and the total amount of system resources actually used or available by the terminal. [0003] The scheduling information is sent by the terminal to the serving node B, and i...
