Title: COMMUNICATION METHOD, DEVICE, AND SYSTEM
Abstract:
The present application provides a communication method, comprising: an access network device and a terminal determine a format of at least one small slot group according to a first subcarrier width used by a first control channel and a second subcarrier width used by a second control channel, respectively; the access network device sends first indication information and second indication information respectively to the terminal, such that the terminal determines a time domain position of each small slot group comprising the second control channel according to the first indication information, and determines time domain positions of small slots, in each small slot group, comprising the second control channel according to the format of the small slot group and the second indication information. The method of the present application can flexibly indicate time domain positions of small slots comprising a second control channel according to the change in a subcarrier width used by the second control channel; a terminal can only detect some of the small slots, such that the energy the terminal consumes to detect each small slot is reduced.
