Embodiment Construction

[0074] The decoding method and device of the embodiment of the present invention uses historical data to make this judgment when the MF result is unreliable, so it can avoid the wrong judgment result caused by using the untrustworthy MF result to make the judgment, and improve the E- Accuracy of HICH.

[0075] The decoding method of the embodiment of the present invention, such as image 3 shown, including:

[0076] Obtain the spread code codeword sequence used by the E-HICH to send the transmission response information;

[0077] Carrying out soft bit mapping to the codeword sequence of the spreading code to obtain the soft bit sequence of the codeword of the local spreading code;

[0078] Perform matched filtering calculation on the soft bit sequence of the code word of the local spreading code and the soft bit sequence detected from E-HICH, and obtain the current matched filtering result;

[0079] Judging whether the current matched filtering result is credible, and obtai...

Abstract

The invention discloses a decoding method and a decoding device. The decoding method comprises the following steps: acquiring an extended code codeword sequence used for an E-HICH to send transmission response information; carrying out soft bit mapping to obtain a local extended code codeword soft bit sequence; performing matched filtering calculation on the local extended code codeword soft bit sequence and a soft bit sequence detected from the E-HICH to obtain a current matched filtering result; making a judgment according to the relationship between the current matched filtering calculation result and a judgment threshold to obtain a first judgment result when the current matched filtering result is credible; making a judgment according to historical values of judgment-related parameters to obtain a second judgment result when the current matched filtering result is not credible; and storing the values of the judgment-related parameters corresponding to the acquired first or second judgment result. The decoding performance of the E-HICH is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a decoding method and a decoding device. Background technique [0002] In order to adapt to the rapid growth of data services in mobile networks, the third generation cooperative standard organization (3GPP) introduced the high-speed uplink packet access (HSUPA) technology in Release 6 (Release6). The HSUPA introduced in Release6 is another major improvement in the wireless part of the time-division synchronous code division multiple access (TD-SCDMA) system following the high-speed downlink packet access (HSDPA). [0003] In HSUPA technology, in the downlink direction, in order to support base station scheduling, an enhanced uplink absolute access grant channel (E-AGCH) is added to transmit base station scheduling information, and an enhanced uplink hybrid automatic repeat request (HARQ) response indication channel (E-AGCH) is added. -HICH) to support the transmiss...
