Problems solved by technology

In this way, if the transmission power used can just make the transmission performance of the E-DPDCH channel with a spreading factor of 4 meet the system requirements, then the transmission performance of the E-DPDCH channel with a spreading factor of 2 will not meet the system requirements. It will reduce the receiving performance; if the transmission performance of the E-DPDCH channel with a spreading factor of 2 is to meet the system requirements, the transmission power on the E-DPDCH channel with a spreading factor of 4 will be wasted, and this part of power could have been Transmits more data, thus reducing system uplink throughput

Embodiment Construction

[0059] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0060] Fig. 2 is the flow chart of the first embodiment that the present invention provides, as shown in Fig. 2, the specific processing procedure of the setting method of a kind of data channel gain factor of the present invention comprises the following steps:

[0061] Step 201: Make the spreading factor SF smaller than the set value SF g of data channels converted to SF g / SF spreading factor is SF g The data channel of , calculate the gain factor β of the converted data channel according to the selected parameters sfg .

[0062] Step 202: Determine the spreading factor SF of the data channel in the current data channel set k Is it less than the set value SF g , if yes, go to step 203, otherwise go to step 204.

[0063] Step 203...

Abstract

This invention discloses a set method for gain factors of data channels, which computes gain factor betasfg of the data channel with the spectrum-spread factor not greater than a set value SFg to further compute gain factor betak of the current channel centralizing the data channels and quantizes gain factor betak of the data channels of different spectrum-spread factors. This invention also discloses a set terminal for gain factors of data channels. This invention ensures the proportion relation of gain factors of data channels of different spectrum-spread factors by differentiating spectrum-spread factors to quantize gain factors of data channels to reach the same transmission performance.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method for setting a data channel gain factor and a terminal Background technique [0002] In order to improve the system uplink throughput rate and reduce the uplink delay, 3GPP (3 rd Generation Project Partner, third-generation project partner) introduced the concept of Enhanced Dedicated Channel (Enhanced Dedicated Channel, E-DCH) in the Release 6 series of standards. Incoming (High Speed ​​Uplink Packet Access, HSUPA). In order to support E-DCH, 3GPP introduced a new physical channel E-DPDCH (Enhanced Dedicated Physical Data Channel) in the WCDMA (Wideband Code Division Multiple Access) system to transmit Uplink business data. When using the E-DCH to transmit uplink data, each UE (UserEquipment, user terminal) can only have one E-DCH transmission channel, but this E-DCH transmission channel can be mapped to one or more E-DPDCH physical channels. [0003] In E-...
