METHOD, SYSTEM, BASE STATION AND TERMINAL FOR SENDING MULTIPOINT TRANSMISSION SYSTEM DATA

摘要

The present document provides a method, a multi-point transmission system, a base station and a terminal for transmitting data in a multi-point transmission system. The method includes: for a User Equipment (UE) enabling multi-point transmission, a base station to which a secondary serving cell of the UE belongs adjusting a time when a High Speed Shared Control Channel (HS-SCCH) and a High Speed Dedicated Physical Control Channel (HS-PDSCH) are transmitted to the UE according to frame offset information of the primary and secondary serving cells of the UE, so that a subframe boundary offset between the HS-PDSCHs of the primary and secondary serving cells received by the UE is within a specified range, and a subframe boundary offset between the HS-SCCHs of the primary and secondary serving cells received by the UE is within the same specified range. The technical solution above realizes synchronization of the HS-PDSCH and the HS-SCCH of the primary and secondary serving cell.
