Abstract
Embodiments of the present invention disclose a method, a device, and a system for sending, receiving, and determining timing reference information, and pertain to the communications field. The method for sending timing reference information includes: acquiring access time difference information reported by a mobile terminal; generating timing reference information according to the access time difference information, where the timing reference information includes identifier information of a timing reference cell; and sending the timing reference information to the mobile terminal. By technical means of determining one of two cells with different downlink channel timings as a timing reference cell and using the timing reference cell as a benchmark to feed back HARQ-ACK information, the present invention solves a timing problem encountered when a UE uses a same HS-DPCCH to jointly feed back two pieces of HARQ-ACK information of a serving cell and an assisting serving cell.
