Abstract

Provided are a method for configuring downlink multipoint transmission for a terminal, a method for a terminal to configure downlink multipoint transmission, a radio network controller and a terminal. In the method for configuring downlink multipoint transmission for a terminal, a terminal resides in a main cell and in a CELL_FACH state, a radio network controller indicates the terminal to sift a candidate subordinate cell of CELL_FACH downlink multipoint transmission and receives the candidate subordinate cell of CELL_FACH downlink multipoint transmission reported by the terminal and whether the terminal has the CELL_FACH downlink multipoint transmission capability; the radio network controller sends a downlink multipoint transmission configuration indication to the terminal to indicate the terminal to complete the configuration of the candidate subordinate cell of CELL_FACH downlink multipoint transmission. The implementation of the present invention is advantageous for improving the data throughput rate of a terminal at the cell edge under the CELL_FACH mode and improving user experience.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for configuring downlink multipoint transmission, a terminal, and a wireless network controller. Background technique [0002] In the Release-5 (R5) version of UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System), HSDPA (High Speed ​​Downlink Packages Access) technology is introduced. [0003] The HSDPA channel includes a high-speed shared data channel (HS-PDSCH, HighSpeedPhysicalDataShareChannel), a corresponding downlink shared control channel (HS-SCCH, HighSpeedSharedControlChannel) and an uplink dedicated physical control channel (HS-DPCCH, HighSpeedDedicatedPhysicalControlChannel). The downlink shared control channel (HS-SCCH) carries the control information from MAC-hs to the terminal, including the mobile station identity mark, H-ARQ related parameters and the transmission format used by HS-DSCH. The informa...
