摘要： The present invention provides a method and a communications device for transmitting information. The method includes: determining a quantity N of padding bits according to a quantity M of effective information bits included in a code block and a quantity L of effective input ports of a polar code encoder, where M and L are positive integers, and N is a difference between L and M; determining input bits that are to be input into the polar code encoder, where the input bits include the M effective information bits and the N padding bits; inputting, according to a mapping relationship between the L effective input ports and the input bits, the input bits into the polar code encoder through the L effective input ports to perform coding, so as to obtain coded bits; and transmitting the coded bits. In this way, when the quantity of the effective information bits included in the code block is less than the quantity of the effective input ports of the polar code encoder, coding can be successfully performed in a bit-padding manner by using polar code, thereby ensuring successful information transmission.

摘要： The present invention discloses a method and an apparatus for transmitting indication information. The method includes: determining, according to one or more codebooks, a first codebook to be used by a terminal device to send an uplink data stream; determining codebook indication information used to indicate the first codebook; and determining codebook indication information used to indicate the first codebook. For the method and the apparatus for transmitting indication information according to embodiments of the present invention, a network device determines, according to one or more codebooks, a first codebook to be used by a terminal device to send an uplink data stream, determines codebook indication information used to indicate the first codebook, and sends the codebook indication information to the terminal device, so that the terminal device can determine the first codebook assigned by the network device and transmit data by using the first codebook. Therefore, network capacity of a system can be effectively improved.
