Detect on hs-scch by after the down dispatch information that G-RNTI scrambles, receive the configuration information comprising E-RNTI and H-RNTI that this component promising is joined using this G-RNTI scrambling according to this down dispatch information on hs-scch.
To sum up, the beneficial effect comprise that
In the scheme that the embodiment of the present invention provides, after each terminal unit that the RNTI being used for schedule data transmission joined for component is sent in this group by access network equipment, the schedule information of mark in group that send use this RNTI scrambling to the terminal unit needing scheduling, that comprise this terminal unit, the schedule information of mark in group that the detection of this terminal unit uses this RNTI scrambling, that comprise this terminal unit, and carry out data transmission according to the schedule information detected.Visible, this programme achieves scheduling scheme based on group.
The present invention is to describe with reference to method, equipment (system) and the flow chart of computer program according to embodiments of the present invention and/or block diagram.It should be understood that can be by the flow process in each flow process in computer program instructions flowchart and/or block diagram and/or square frame and flow chart and/or block diagram and/or the combination of square frame.These computer program instructions can be provided to produce a machine to the processor of general purpose computer, special-purpose computer, Embedded Processor or other programmable data processing device so that the instruction performed by the processor of computer or other programmable data processing device is produced for realizing the device of function specified in one flow process of flow chart or multiple flow process and/or one square frame of block diagram or multiple square frame.
These computer program instructions may be alternatively stored in and can guide in the computer-readable memory that computer or other programmable data processing device work in a specific way, the instruction making to be stored in this computer-readable memory produces the manufacture including command device, and this command device realizes the function specified in one flow process of flow chart or multiple flow process and/or one square frame of block diagram or multiple square frame.
These computer program instructions also can be loaded in computer or other programmable data processing device, make to perform sequence of operations step on computer or other programmable devices to produce computer implemented process, thus the instruction performed on computer or other programmable devices provides the step of the function specified in one flow process of flow chart or multiple flow process and/or one square frame of block diagram or multiple square frame for realization.
Although preferred embodiments of the present invention have been described, but those skilled in the art once know basic creative concept, then these embodiments can be made other change and amendment.So, claims are intended to be construed to include preferred embodiment and fall into all changes and the amendment of the scope of the invention.
Obviously, those skilled in the art can carry out various change and modification without departing from the spirit and scope of the present invention to the present invention.So, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
