Abstract: A rate matching method including: determining a receiving capability of a receive end, where the receiving capability is used to indicate a maximum data processing volume of the receive end in a first transmission time, and/or the receiving capability is used to indicate a maximum data buffer volume of the receive end in a first transmission time; the first transmission time is used to transmit a first transport block to which a first code block belongs; determining NCB based on the receiving capability, where NCB represents a code block size used for rate matching; performing rate matching on the first code block based on NCB. The receive end can adjust, based on a processing capability and/or a buffer capability that are/is of the receive end in a period of time, the code block size used for rate de-matching, to avoid insufficiency in processing capability and/or buffer overflow at the receive end.

Abstract: Example polar code-based transmission methods and apparatus are provided, to apply polar encoding to a physical broadcast channel (PBCH). One example method includes performing polar encoding on a to-be-encoded first bit sequence by a transmit end to generate an encoded sequence. The transmit end performs a transformation operation on the encoded sequence to obtain a second bit sequence, where the transformation operation includes at least one of scrambling, interleaving, or reordering. The transmit end sends the second bit sequence in M inconsecutive time units, where at least two time intervals between the time units in the M inconsecutive time units are unequal.

Abstract: A terminal device determines a resource of a physical uplink control channel. The physical uplink control channel carries a first encoded bit sequence and a second encoded bit sequence, the first encoded bit sequence is corresponding to first uplink control information, and the second encoded bit sequence is corresponding to second uplink control information. The resource for the physical uplink control channel includes N orthogonal frequency division multiplexing (OFDM) symbol sets. The first encoded bit sequence is carried in an OFDM symbol included in j OFDM symbol sets, the j OFDM symbol sets are a part of or all of of the N OFDM symbol sets, where j is a positive integer less than or equal to N. The terminal device sends, on the resource for the physical uplink control channel, a signal that is generated based on the first uplink control information and the second uplink control information.
