Problems solved by technology

If Node B can only schedule a small number of EUDCH data channels at the same time, if many EUDCH users send uplink scheduling request signaling at the same time, most of the uplink scheduling request signaling will not be responded, resulting in waste, and the uplink scheduling Too much request signaling will cause increased uplink interference

Embodiment Construction

[0031]The present invention proposes a method for Node B to flexibly control UE to send uplink scheduling request signaling in EUDCH. The existing Node B-controlled scheduling method increases the control of EUDCH users sending uplink scheduling request signaling, and reduces uplink interference.

[0032] figure 2 It is a schematic diagram of the idea of ​​the present invention. Such as figure 2 As shown in block 201, the Node B generates EUDCH uplink signaling general speed control parameters.

[0033] In module 202, the Node B broadcasts the EUDCH uplink signaling general speed control parameters to all EUDCH users.

[0034] In module 203, EUDCH users need to send uplink signaling to change the TFC subset controlled by Node B, and before sending uplink signaling, they must be controlled by general speed control parameters. If the TTI is allowed to send uplink signaling, go to step 204 . In step 204, uplink signaling is sent. Otherwise, the processing of this TTI ends...

Abstract

A means for controlling EUDCH user sending upgoing request signal, including steps: Node B calculates general speed control parameter of the upgoing signal of the EUDCH user in next cycle; NodeB broadcasts the parameter to users; EUDCH user designs whether its TTI sends upgoing request signal according to the general speed control parameter before he sends upgoing signal to change the TFC subset which is controlled by the NodeB, if it can sends, TTI sends the upgoing signal, if it can not, TTI does not send the upgoing signal. The invention can equipped user signal general speed control parameter according to the current surveying RoT and EUDCH user and control the probability that EUDCH user sends upgoing-dispatching signal flexibly.

Description

technical field [0001] The present invention relates to the third-generation mobile communication, and particularly relates to a method for flexibly controlling the uplink scheduling request signaling sent by the EUDCH user terminal in the dedicated channel uplink enhancement (hereinafter referred to as EUDCH). Background technique [0002] The second generation mobile communication system includes GSM (Global System for Mobile Communications) and IS (Interim Standard)-95, the main goal is to provide voice services. GSM adopts TDMA (Time Division Multiple Access) technology, which was commercialized in 1992 and is mainly used in Europe and China. What IS-95 uses is code division multiple access technology, mainly used in the United States and South Korea. [0003] At present, mobile communication technology has evolved into the third generation mobile communication system, which provides high-speed and high-quality data services and multimedia services in addition to voice ...
