Abstract
The present disclosure provides a data transmitting method. The method includes that a device detects SA, generates a DMRS sequence and a scrambling code of a data channel for the SA correctly decoded; and performs processing for the data channel scheduled by the SA correctly decoded according to the DMRS sequence and the scrambling code. According to the method of the present disclosure, MDRS sequence randomization and scrambling code randomization of the data channel can be better supported, so as to optimize transmission performance.
Claims21
A data transmitting method in a wireless communication system, the method comprising:
- identifying scheduling assignment information for transmitting the data;
- identifying cyclic redundancy check (CRC) information based on the scheduling assignment information;
- transmitting the scheduling assignment information and the CRC information to a terminal in a first subframe;
- and
- transmitting the data and a demodulation reference signal (DMRS) for the data to the terminal based on the scheduling assignment information in the first subframe,
- wherein the data and the DMRS are generated based on the CRC information which is 16 bits.
