INFORMATION TRANSMISSION METHOD AND DEVICE

摘要

The present invention provides an information transmission method and apparatus. The information transmission method includes: obtaining, by a terminal, subframe configuration information of at least two serving cells, and transmitting, by the terminal according to HARQ timing relationships respectively corresponding to the at least two serving cells, information with a network side device in uplink subframes and/or downlink subframes indicated by the subframe configuration information; where the at least two serving cells include at least one first serving cell, where an HARQ timing relationship of the first serving cell is an HARQ timing relationship of TDD configuration n, and an uplink and downlink configuration of TDD configuration n is different from an uplink and downlink configuration of the first serving cell; or, a timing relationship of a first downlink subframe set of the first serving cell is an HARQ timing relationship of FDD and a timing relationship of a second downlink subframe set is an HARQ timing relationship of TDD.
