Problems solved by technology

[0018] The disadvantage of the method of decoding operation on the NodeB side in the above-mentioned prior art is: the decoding operation on the E-DPCCH of one channel needs to perform 1024*30=30720 multiplication and addition operations, and the amount of calculation is very huge, so the decoding speed is relatively high. slow

Embodiment Construction

[0047] The present invention provides a method for improving the decoding speed of the base station. The core of the present invention is: the NodeB and the UE use the known size and content of the uplink available transmission format subset used by the UE to convert it into the available transmission format subset The index number of is used as a valid information bit of the uplink transmission format indication information. Furthermore, the NodeB determines the number of effective bits of the channel (such as E-DPCCH) where the uplink transmission format indication information is located, calculates the dimension of the matrix (such as Hardamard) to be used, and reduces the dimension of the matrix to improve the base station's uplink The transport format dictates the decoding speed of the channel on which the information resides.

[0048] The present invention will be described in detail below in conjunction with the accompanying drawings. The present invention takes the int...

Abstract

The invention relates to a method for improving the decoding speed of base station. Wherein, it comprises: user end uses its index number in available transmission format subset as the effective information bit in the ascending transmission format instruction information; sends said ascending transmission format instruction information via its signal channel to the base station; the base station based on the effective information bits, decodes the message of user end sent at the signal channel of ascending transmission format instruction information. The inventive method can reduce the calculation on decoding operation and improve the decoding speed of base station.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for enhancing the decoding speed of a base station. Background technique [0002] With the development of third-generation mobile communication systems such as UMTS (Universal Mobile Telecommunications System), people's demand for mobile communication is no longer satisfied with traditional voice services. High data rate services, so a large number of multimedia services have emerged in the third-generation mobile communication system, such as: video calls, picture uploads, high-speed Internet browsing and other services. Therefore, in the third generation mobile communication system, in order to enhance the uplink capacity and user uplink performance, an enhanced uplink technology (that is, high-speed uplink packet access) is introduced. [0003] In the enhanced uplink technology, an important feature is flexible NodeB (base station) scheduling control. The resource indicati...
