摘要

Embodiments of the present invention provide a control information transmission method and apparatus. The control information transmission method includes: determining, by a network device, N pieces of to-be-jointly-coded downlink control information DCI, where N is an integer greater than or equal to 2; coding, by the network device, the N pieces of DCI in a polar coding manner, to obtain one codeword; and mapping, by the network device, the codeword to a time-frequency resource of a downlink control channel for sending. According to the embodiments of the present invention, not only a relatively high coding gain can be obtained, but a relatively low average processing latency on a decoder side can also be obtained.
