    Abstract: Embodiments of this application disclose a resource mapping method and an apparatus. The method includes: network device performs nested-structure mapping on a modulated symbol set to obtain a first resource block, where the modulated symbol set carries downlink control information corresponding to each of at least one user equipment, and modulated symbols of same user equipment that are carried on the first resource block are consecutive; then reconstructs, the first resource block to obtain a second resource block, where modulated symbols of same user equipment that are carried on the second resource block are non-consecutive; and maps the second resource block to a time-frequency resource, so that the user equipment obtains the modulated symbol set based on the time-frequency resource.

    Abstract: Embodiments of the application provide a method for transmitting data in a wireless communication network. A device of the network receives a bit sequence of K information bits. The device polar codes the bit sequence to obtain a first encoded sequence, wherein a length of the first encoded sequence is N, and N is greater than or equal to K. The device block interleaves the first encoded sequence to obtain an interleaved bit sequence. The device determines a transmission code rate R. When the transmission code rate R is less than the code rate threshold, the device outputs a second bit sequence. The length of the second bit sequence is M, M is smaller than N. The second bit sequence is punctured from the interleaved bit sequence by removing (N−M) bits from beginning of the interleaved bit sequence.

    Abstract: The application provides manner for communicating channel state information (CSI) in a communication network. A preset length is used for equalizing lengths of CSI to be reported. The preset length is determined based on a quantity of CSI-reference signal (RS) ports. A communication device determines whether a total length of one or more indication information items to be included in the CSI is less than the preset length. If the total length of the one or more indication information items to be included in the CSI is less than the preset length, the communication device adds one or more padding bits, to obtain a CSI bit sequence including the one or more indication information items and the one or more padding bits. A total length of the CSI bit sequence is consistent with the preset length. The communication device then outputs the CSI bit sequence.

    Abstract: Embodiments of this application provides a communication method in a wireless communication network. A communication device obtains an information bit sequence and obtain a first sequence, wherein the first sequence comprises sequence numbers of N channels ordered in ascending order of channel reliability, wherein N is 1024 and wherein a channel whose sequence number is 0, a channel whose sequence number is 1, and a channel whose sequence number is 2 are ordered in ascending order of channel reliability; then polar encode the information bits based on the first sequence to obtain an encoded bit sequence and output the encoded bit sequence.

    Abstract: A rate matching method for a polar code is provided, to improve performance. The method includes: encoding, based on an N*N encoding matrix of a polar code, a sequence including N first bits, to generate a mother code including N second bits, where the N first bits are in a one-to-one correspondence with N rows in the encoding matrix in sequence, and the N second bits are in a one-to-one correspondence with N columns in the encoding matrix in sequence; determining N−M to-be-punctured second bits from the N second bits, where at least one first bit in N−M first bits participating in encoding of the N−M second bits belongs to the first M first bits in the N first bits, and the N−M first bits are fixed bits; and puncturing the N−M second bits, to obtain a target polar code including M second bits.
