For the objects, technical solutions and advantages of the present invention are more clearly understood, develop simultaneously embodiment referring to the drawings, right
Scheme of the present invention is described in further detail.
A kind of terminal measurement reporting method is proposed in the embodiment of the present invention, applied to macrocell and Microcell alien frequencies is overlapping covers
Lid, and chain of command and user's separation, Microcell only have user plane, for chain of command all in the scene of macrocell, macrocell can also
There is user plane.Connected between macrocell and Microcell by non-ideal return link.
In the specific embodiment of the invention different Physical Cell Identifier (Physical is used for macrocell and Microcell
Cell ID), enable the terminals to distinguish which mark corresponding to cell be macrocell, that identify corresponding to cell be Microcell.
During specific implementation, it can such as arrange the inhomogeneous cell of Digital ID in different pieces of information section；Increasing can also be passed through
Add the mark which kind of cell the differentiation of the marks such as letter is.It is not limited, can be answered according to specific in the specific embodiment of the invention
With determination implementation.
In the application scenarios of the embodiment of the present invention, terminal is when in connection status, it is still desirable to measuring reference signals
Receiving power (Reference Signal Receiving Power, RSRP), Reference Signal Received Quality (Reference
Signal Receiving Quality, RSRQ) and channel condition information (Channel State Information, CSI),
Therefore, terminal still needs to obtain the cell information of macrocell, and the cell letter of the Microcell of covering overlapping with the macrocell
Breath, the coverage that overlapping covering here refers to macrocell are more than the coverage of Microcell.
During specific implementation, macrocell broadcast transmission carries the RRC signaling of its cell information；Broadcast transmission is carried and overlapped
Cover the RRC signaling of the cell information of Microcell.
When the terminal of covering overlapping with the macrocell receives the RRC signaling for carrying its cell information of macrocell broadcast,
Obtain the cell information of the macrocell；When receiving the RRC signaling of the cell information of the carrying Microcell of macrocell broadcast, obtain
The cell information of the Microcell.
Broadcast for the cell information of macrocell is consistent with processing mode in the unseparated scene of user plane with chain of command；
Broadcast for the cell information of Microcell is different from the processing mode in chain of command and the unseparated scene of user plane, this implementation
No longer it is by its cell information of Microcell own broadcast in example；But the cell information of the Microcell is broadcasted by macrocell.
The cell information for the Microcell that covering is overlapped due to macrocell broadcast is the realization that newly increases, therefore, this hair
Bright specific embodiment is in specific implementation, the RRC signaling of the cell information of the Microcell for overlapping covering of macrocell broadcast

CSI, and report the macrocell.
When terminal processes connection status, handover between cells may both occur, it is also desirable to data transfer, therefore, it is necessary to
RSRP, RSRQ and CSI of Microcell are measured, but due to not having chain of command on Microcell, cell will not be carried out by Microcell
Between switch, therefore, RSRP and RSRQ for the small region measurement are reported to the macrocell for overlapping covering；And will measurement
The CSI feedback of the obtained Microcell gives the Microcell user data transmission.
Due to having chain of command on macrocell, it is also possible to by user plane, therefore, need to measure RSRP, RSRQ for macrocell
With CSI and all report macrocell, for handover between cells and data transfer.
Step 102, the macrocell receives the RSRP and RSRQ for the Microcell that the terminal reports, for determining that this is small
Whether area is the terminal service.
Microcell receives the CSI that the terminal reports, and the CSI reported according to this carries out data transmission.
When the terminal is in idle condition, it is contemplated that Microcell is now only needed grand without data transfer, terminal
Switched between cell, therefore, do not measure and do not report RSRP, RSRQ and CSI of the Microcell (to greatly reduce signaling
Expense)；The RSRP and RSRQ of the macrocell are measured, and reports the macrocell.
Macrocell receives the RSRP and RSRQ of this macrocell that terminal reports, and is used to determine whether to carry out cutting for minizone
