Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] figure 1 It is a processing flow chart of the analysis method for combining calculation values ​​into transmission format indications according to the present invention. like figure 1 As shown, the analysis method of the present invention to realize the transmission format combination calculation value to the transmission format indication is specifically divided into the following processing steps:

[0038] Step 1. The receiver obtains the transmission format combination calculation value CTFC, the number I of transmission channels and the number L of transmission formats of each transmission channel through the physical layer signaling of the transmission format combination indication TFCI 1 , L 2 ...,L I value;

[0039] Step 2, setting the initial values ​​of the intermediate variable T_CTFC and the loop variable i to be the tra...

Abstract

This invention relates to an analysis method from the transmission form combined computing value (CTFC) to the transmission form instruction(TFI) of each transmission channel. TFI of each transmissionchannel is got by recursion pattern and contain operation of CTFC and transmission from number L of each channel including the following steps: L1, L2. L1 a receiving party obtains parameter CTFC, transmit channel number and form numbers by the TFCI physical signaling, setting the initial value of the intermediate variable T-CTFC and circulation variable I to be CTFC and 1, carrying out circulation operation TFIi=T-CTFC MODLi, T-CTFC=T-CTFC DIVLi, among which, MOD and DIV are pattern and contain operation separately, adding 1 to I, carrying out next circulation till I=I get TF1.
