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: Embodiment techniques map parity bits to sub-channels based on their row weights. The row weight for a sub-channel may be viewed as the number of “ones” in the corresponding row of the Kronecker matrix or as a power of 2 with the exponent (i.e. the hamming weight) being the number of “ones” in the binary representation of the sub-channel index (further described below). In one embodiment, candidate sub-channels that have certain row weight values are reserved for parity bit(s). Thereafter, K information bits may be mapped to the K most reliable remaining sub-channels, and a number of frozen bits (e.g. N−K) may be mapped to the least reliable remaining sub-channels. Parity bits may then mapped to the candidate sub-channels, and parity bit values are determined based on a function of the information bits.

Abstract: User equipment receives at least one TAC that is broadcast by a network device, where the TAC includes geographical location information, and the geographical location information is used to indicate a geographical location of a preset location point in a TA corresponding to the TAC. The user equipment determines, based on the TAC and a tracking area list (TAL), whether the TAL needs to be updated. If it is determined that the TAL needs to be updated, the user equipment sends a tracking area update request to the network device. The user equipment receives a response message, of the tracking area update request, returned by the network device.
