1. A method, comprising:
- receiving a first control channel from a network device, wherein the first control channel is mapped to M consecutively-numbered transmission elements, the first control channel is used to schedule a data channel, each transmission element of the M consecutively-numbered transmission elements is respectively a smallest unit used to transmit the first control channel, and M≥
1, and wherein each of the M consecutively-numbered transmission elements comprises T groups of resource elements (REs); and
receiving or sending data on the data channel based on the first control channel;
wherein the first control channel is mapped to the M consecutively-numbered transmission elements in an interleaved mapping manner that comprises;
successively occupying a respective ith group of REs in each of the M consecutively-numbered transmission elements; and
after all the respective ith groups of REs in each of the M consecutively-numbered transmission elements are occupied, successively occupying a respective (i+1)th group of REs in each of the M consecutively-numbered transmission elements, wherein T≥
2, and a value of i ranges from 1 to T.
