METHOD, DEVICE, AND SYSTEM FOR SENDING, RECEIVING, AND DETERMINING TIMING REFERENCE INFORMATION

摘要

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.

主权项

1. A method for sending timing reference information, wherein the method is used in a communications system comprising two cells with different downlink channel timings, wherein the two cells both adopt a hybrid automatic repeat request process in high speed downlink packet access to perform downlink transmission, and the method comprises:
acquiring access time difference information reported by a mobile terminal; generating timing reference information according to the access time difference information, wherein the timing reference information comprises identifier information of a timing reference cell; and sending the timing reference information to the mobile terminal.
