Embodiment Construction

[0061]The HSDPA channel includes two new transmission channels and corresponding physical channels: HS-SCCH and HS-DSCH. Since HS-SCCH and HS-DSCH and their physical channels support a wide range of data rates and modulation formats, in order to ensure the comprehensive test coverage of the transmission performance of the HSPDA channel, and the investment is small, it is necessary to design a set The minimum set of sufficient minimum test sequences, and at the same time, the test adequacy needs to be designed after the minimum set is found.

[0062] Based on the above requirements, the present invention mainly adopts a method of randomly generating HSDPA transmission and physical channel test sequences to generate the test sequence, and based on the test sequence to test the transmission performance of the HSPDA channel; generation of the test sequence By subdividing the various processing stages of HSDPA transmission and physical channels, a minimum set of test sequences is given...

Abstract

This invention relates to method to test HSDPA signal channel transmission property, which adopts One random generation HSDPA transmission and physical signal channel testing sequence method to generate test sequence and testing the transmission property based on the said test sequence; testing sequence generation through divided HSDPA transmission and physical signal channel each process phase to give one test sequence minimum set and then on the base forming abundant test sequence set through overlapping.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a method for testing the transmission performance of an HSDPA channel. Background technique [0002] HSDPA (High Speed ​​Downlink Packet Data Transmission) is a key technology in the third-generation mobile communication system WCDMA (Wideband Code Division Multiple Access) standard R5 version. HSDPA technology can realize high-speed data transmission in a shared manner, thereby enhancing WCDMA downlink data Transmission capabilities enrich the types of services provided. [0003] The HSDPA technology introduces two new transmission channels and corresponding physical channels for the WCDMA standard: HS-SCCH (High-speed Downlink Shared Channel Shared Control Channel) and HS-DSCH (High-speed Downlink Shared Channel). [0004] At present, the standards for HSDPA technology have been basically formulated, but products with HSDPA functions have not yet been provide...
