Problems solved by technology

[0003] In the prior art, the power of SCCPCH does not change with the size of the FACH transport block carried by it
In addition, in the TD-SCDMA system, the FACH can also be shaped, and the SCCPCH power does not change depending on whether the FACH is shaped or not in the prior art.
In this way, power will be wasted and unnecessary interference will be increased

Embodiment Construction

[0023] The preferred embodiments of this solution will be described below in conjunction with the accompanying drawings.

[0024] Please refer to figure 1 , is a flow chart of the first embodiment of a method for controlling FACH power and SCCPCH power of the present invention, the method comprising:

[0025] s101. Setting the power level parameter of the forward access channel FACH;

[0026] The power level parameter of the FACH is carried in the frame of the FACH, and the power level parameter of the FACH can be directly provided by the manufacturer's equipment, or can be determined according to the size of the transmission block, whether it is shaped, user path loss, etc. .

[0027] Setting the power level parameters of the forward access channel FACH can be based on one or any combination of the following factors:

[0028] The transmission block coding gain of the FACH, the shaping gain and the transmission path loss of the FACH.

[0029] The FACH power is determined a...

Abstract

The present invention relates to a mobile communication field, and discloses a method for controlling the FACH power and the SCCPCH power. The method comprises the following procedures: transmitting the power grade parameter of the forward access channel FACH by a radio network controller RNC to a base station Node B; and calculating the power of the FACH and the power of the secondary common control physical channel SCCPCH by the base station Node B according to the power grade parameter. At the same time, the invention also discloses a corresponding system. The power of FACH and power of the SCCPCH can be adjusted to the appropriate magnitude through the method and system for controlling the power of the FACH and the power of the SCCPCH thereby reducing the interference and increasing the capability to obtain the effective utilization of the power.

Description

technical field [0001] The present invention relates to mobile communication, in particular to a method and system for controlling FACH power and SCCPCH power. Background technique [0002] In the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access technology) system, according to the 3GPP protocol, the common transmission channel FACH (Forward Access Channel, forward access channel) will be mapped to the SCCPCH ( Secondary Common Control Physical Channel, secondary common control physical channel). The current general implementation is that the Node B directly uses the SCCPCH power configured by the RNC (Radio Network Controller, radio network controller) to transmit on the air interface, without using the power level parameter of the transmission channel, which includes the following steps: RNC directly configures the Node B The power of the SCCPCH; the power of the FACH is generated according to the p...
