Abstract: A signal processing method and an apparatus thereof. A first signal is received, wherein the first signal includes x symbols. N types of quantization levels are determined based on a signal distribution parameter of the first signal. A second signal is determined based on the first signal. Quantization processing is performed on the second signal to obtain x groups of first quantization results, wherein the x symbols are in one-to-one correspondence with the x groups of first quantization results. The x groups of first quantization results are mapped to a quantized first signal, wherein the quantized first signal includes x quantization levels, and each group of first quantization results is mapped to one of the N types of quantization levels. Signal processing is performed on the quantized first signal.

Abstract: A method for determining an auxiliary bit of a polar code and an apparatus. At least K sub-channels are determined based on reliability of a first sub-channel set, where the K sub-channels carry information bits. S sub-channel subsets are determined based on the first sub-channel set, an ith sub-channel subset in the S sub-channel subsets includes Ji sub-channels carrying auxiliary bits and Ki sub-channels in the K sub-channels. Sequence numbers of the Ji sub-channels carrying the auxiliary bits are after sequence numbers of the Ki sub-channels. The auxiliary bits are known redundancy check RC bits. Polar encoding is performed on the information bits and the auxiliary bits, to output polar-encoded data.

Abstract: This application provides a scheduling method, a scheduling system, and a scheduling apparatus. After obtaining a reward feedback for a previous scheduling decision sent by a terminal device, a scheduler may send, in N time units after the reward feedback is received, a current scheduling decision calculated based on the reward feedback, where N>1 and N is an integer, so that sufficient time can be left for the scheduler to calculate and code the scheduling decision, thereby effectively resolve a problem that a scheduling procedure mismatches and conflicts with an over-the-air time sequence when the scheduler cannot obtain a reward of the previous scheduling decision in time.
