Problems solved by technology

The UE performs the above-mentioned blind detection of the transmission format, which is very complicated to implement, and the calculation of decoding and CRC check is very large
Especially when there are many TrCHs mapped to the CCTrCH or the TFCS contains many TFCs, the above blind transmission format detection process will consume a lot of time and system resources

Embodiment Construction

[0027] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.

[0028] figure 1 The flow chart of the method of the present invention is shown. Such as figure 1 Shown, the inventive method comprises the steps:

[0029] In step 10, the UE, as the receiving end of the downlink, determines the blind detection mode adopted by each TrCH according to the TFCS configured by the RNC.

[0030] When establishing a service link, the RNC will configure CCTrCH information to the corresponding NodeB and UE, including transmission channel parameters, TFCS corresponding to the CCTrCH, and physical channel parameters.

[0031] Step 20, judging whether there is a transmission channel for blind detection based on the guide, if yes, go to step 30,...

Abstract

The invention discloses a transmission format blind detection method of a user terminal based on a guide. The transmission format blind detection method can reduce the complexity of transmission format blind detection and comprises the steps: determining blind detection modes adopted by transmission channels according to a transmission format combinatorial set configured by a wireless network controller by the user terminal, obtaining the transmission channels and collecting data in one transmission time interval of the transmission channels; obtaining data before decoding in one transmissiontime interval of the transmission channels, respectively processing the data before decoding in one transmission time interval of each transmission channel in a respective blind detection mode, and verifying the transmission format. The invention reduces the complexity of transmission format blind detection and the amount of calculation.

Description

technical field [0001] The present invention relates to a transmission format blind detection method, in particular to a user terminal guide-based transmission format blind detection method. Background technique [0002] WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) is a widely influential standard in 3G (third generation mobile communication system), and will inevitably occupy an important position in the 3G market structure. In a WCDMA system, data carried on each TrCH (Transport Channel, transport channel) is a data transmission block or a data transmission block set that occurs periodically in a TTI (Transmission Time Interval). Different TrCHs may have different TTIs. In the process of data transmission, the TrCH carrying these data transmission blocks is multiplexed together after channel coding to form a CCTrCH (Coded Composite Transport Channel, coded composite transport channel), and then the physical channel is divided and ...
