3GPP New Radio Base Graph Selection

摘要

According to some embodiments, the method used in a wireless transmitter of a wireless communication network that encodes a transport block has a code rate of R_threshold or less (R_threshold is 1/5 and 1) for transmitting the transport block. Determining (with / 3) includes selecting base graph 2 of the New Radio (NR) Low Density Parity Check (LDPC) for encoding the transport block. Otherwise, the method encodes the transport block unless the transport block size (TBS) of the transport block is less than or equal to the size threshold (X) and the code rate for transmitting the transport block is less than or equal to 2/3. The method may include selecting the base graph 1 of the NR LDPC to be made, in which case the method may include selecting the base graph 2. The method further comprises encoding the transport block using the selected base graph and transmitting the encoded transport block to the radio receiver. [Selection diagram] Fig. 6
