Abstract: This application provides a method for communicating a modulation and coding scheme (MCS). A terminal device obtains a modulation order, a code rate, or a spectral efficiency, determines an index of a reference MCS from a mapping table based on the obtained modulation order, code rate, or spectral efficiency, and reports the index of the reference MCS to a network device. The mapping table includes one or more mapping relationships between an MCS index and a modulation order, a code rate, or a spectral efficiency. The terminal device may process uplink or downlink data based on the determined MCS, thereby improving data transmission reliability.

Abstract: Embodiments of this application disclose a polar coding method, apparatus, and device, so as to reduce storage overheads of a system. A sequence for polar coding is obtained based on a length M of a target polar code, wherein the sequence comprises L sequence numbers, ordering of the L sequence numbers in the sequence is the same as ordering of the L sequence numbers in a maximum mother code sequence, wherein the maximum mother code sequence is obtained by sorting N sequence numbers of N polarized channels in ascending order or descending order of reliability metrics, wherein L and N are integer power of 2, M is smaller than or equal to L, L is smaller than or equal to N.

Abstract: This application describes examples of antenna modules, MIMO antennas, and terminals. One example antenna module includes a clearance area, a support, and at least two branches. Each branch is disposed on the support, and a partial projection of the support on a horizontal plane falls within the clearance area, while a projection on the horizontal plane of one end that is of each branch and that is configured to connect to a feed point is outside the clearance area. A projection of a tail end on the horizontal plane is inside the clearance area.

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.
