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.

1. A method for transmitting data in a multi-point transmission system, comprising:
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 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 method further comprising: the base station to which the secondary serving cell belongs obtaining the frame offset information by any one of the following modes: the UE measuring the frame timing information of the primary and secondary serving cells, calculating and obtaining frame offset information according to the frame timing information, and reporting the frame offset information to a radio network controller, and the radio network controller transmitting the frame offset information to the base station to which the secondary serving cell belongs; the UE measuring and obtaining the frame timing information of the primary and secondary serving cells, and transmitting the frame timing information to a radio network controller; and the radio network controller obtaining the frame offset information according to the frame timing information, and transmitting the frame offset information to the base station to which the secondary serving cell belongs; the UE measuring and obtaining the frame timing information of the primary and secondary serving cells, and transmitting the frame timing information to a radio network controller; the radio network controller transmitting the frame timing information to the base station to which the secondary serving cell belongs; and the base station to which the secondary serving cell belongs obtaining the frame offset information according to the frame timing information.
