Description
Technical field
The present invention relates to wireless communication technology field, more particularly to a kind of method for carrying out up transfer, system and equipment.
Background technology
Current LTE (Long Term Evolution, Long Term Evolution) system, can only there is a carrier wave in a cell,
And maximum bandwidth is 20Mhz.For LTE-A (LTE-Advanced strengthens Long Term Evolution) system, the peak value of lte-a system
Speed ratio LTE system is greatly improved, and lte-a system requirement reaches descending 1Gbps, up 500Mbps.Obviously, 20Mhz
Bandwidth cannot meet this demand.In order to lte-a system can be met the requirements, CA (Carrier are introduced
Aggregation, carrier aggregation) technology.
Carrier aggregation technology is that terminal can simultaneously work in multiple cells, and these cells can be continuous on frequency domain
Or it is discrete, the bandwidth of each cell can be with identical or difference.To keep compatible with LTE system, each cell is most
Big bandwidth is limited to 20MHz.At present it is generally acknowledged that the cell form of a user terminal polymerization is 5 to the maximum.Additionally, based on not
Difference in functionality may be supported with cell, cell of the lte-a system also to user terminal polymerization is classified, as follows：
PCell (Primary Cell, main plot)：Only one of which cell is defined as in the multiple cells of terminal polymerization
PCell, PCell by base station selected, and by RRC (Radio Resource Control, wireless heterogeneous networks) signal deployment
To terminal.PUCCH (Physical Uplink Control Channel, physical layer upload control are configured with only PCell
Channel).
SCell (secondary cell, Secondary Cell)：Cell in all cells of terminal polymerization in addition to PCell
All it is SCell.
The regulation UE of LTE-AR (Release, version) 10/R 11 are only capable of sending PUCCH on PCell.So no matter UE gathers
The different districts of conjunction receive descending using the duplex mode of identical (or different) by from which carrier wave (or which sending entity)
Signaling (or data), is required for the uplink transmission power of UE to be promoted to the degree that macro base station can be received.Such as R10UE carrier waves
The different scenes of polymerization, the different carrier waves of UE polymerizations belong to same base station entity, and the scheduling of UE is equal with up-downgoing data transmit-receive
Controlled by same base station entity.Even if by RRH (Remote Radio Heads, far end radio frequency head) remote radios or making
Supplemented with repeaters (repeater) and covered, the descending of UE can be received by RRH entities or repeaters entities, but by
Only it is limited in dominant frequency point (PCC) in uplink such as PUCCH/UL SPS, it is necessary to directly receive the up of UE by base station entity.
For the UE of LTE R10/R11 versions, the carrier resource of its same base station that is only capable of being polymerized, therefore according to current
Measurement mechanism, base station can determine that terminal carries out data transmission reducing by which cell and disturb and economize on electricity.
But the UE of R12 versions is possible to the resource of the multiple base stations of polymerization simultaneously, if local node is under grand covering,
The uplink such as its PUCCH/UL SPS are still kept only by leading apart from the slightly remote UE of macro base station for being covered down in local node
The limitation that frequency is received, can increase and disturb and be unfavorable for that UE economizes on electricity.
The content of the invention
A kind of method for carrying out up transfer provided in an embodiment of the present invention, system and equipment, are used to solve prior art
Present in local node be in grand covering under, still keep it apart from the slightly remote UE of macro base station for being covered down in local node

Specific embodiment
Embodiment of the present invention network side equipment according to circuit loss value it is determined that user equipment up needs transfer after, by user
The up of equipment is transferred on local node；Or user equipment according to circuit loss value it is determined that the up needs transfer of user equipment is logical
Know network side equipment, up by user equipment is transferred on local node.Due to that can be that UE selections are carried out according to path loss
The node of row transmission, can be it for being collectively covered down but apart from the slightly remote UE of macro base station in local node and macro base station
The less local node of selection path loss receives the upward signal of UE, so as to reduce the transmission power of UE, reduction is disturbed and saved
The electricity of UE.
Wherein, the local node in the embodiment of the present invention includes but is not limited at least one of following：

Shift；Can also judge whether the up of user equipment needs transfer and report network side by user equipment according to circuit loss value
Equipment, is introduced separately below.
First, network side equipment judges whether the up of user equipment needs transfer according to circuit loss value.
As shown in figure 1, the embodiment of the present invention the first method for carrying out up transfer comprises the following steps：
Step 101, network side equipment are according to the circuit loss value between user equipment and at least one local node and user
Circuit loss value between equipment and network side equipment, judges whether the up of user equipment needs transfer；
Step 102, network side equipment it is determined that user equipment up needs transfer after, by the up transfer of user equipment
Onto local node.
It is preferred that in step 101, network side equipment determines that the mode of the circuit loss value between user equipment and local node has
Many kinds, are set forth below several：
Mode one, network side equipment is according to the reference signal power value of at least one local node and user equipment to report
Reference Signal Received Power value, determines the circuit loss value between user equipment and local node.
In force, reference signal power value and user equipment to report of the network side equipment according at least one local node
Reference Signal Received Power value, determining the mode of the circuit loss value between user equipment and local node has many kinds：
Such as network side equipment can be by the reference signal power information of other nodes of acquisition, and the RRM for passing through UE
Measurement reports content, determines the circuit loss value between UE and different local nodes.
The RRM measurements that R10 UE are reported report the signal intensity and/or signal that multiple Serving cells can be carried in content
Quality.Network side equipment passes through the signal measurement amount of multiple Serving cells for receiving, with local node/transmission power difference,
May determine that whether UE is nearer apart from local node, and then judge whether to be fully transferred to local node to reduce by the up of UE
The up generation power of UE, saves UE electricity, specifically may refer to Figure 10.
Network side equipment is according to the reference signal power value of at least one local node and the reference letter of user equipment to report
Number received power value, determines that the formula of the circuit loss value between user equipment and local node may refer to 3GPP TS 36.213 and assist
View, will not be repeated here.

Road common configuration) the middle CRS power for obtaining primary/secondary cell, the RSRP values of primary/secondary cell can be measured and path loss formula is utilized,
Calculate the path loss between UE and each cell.Local node in the embodiment of the present invention, because it is likely to be at not with macro base station
Frequency where same geographical position, and local node and macro base station it is not consistent, it is necessary to recalculate UE and local node it
Between path loss.
User equipment is it is determined that " reference signal power " needs to be set to same with " Reference Signal Received Power " during circuit loss value
The parameter of the reference signal of class, can only simultaneously be CRS, or be CSI-RS's.If so network interaction is
CSI-RS power, if the receiving power of UE measurements also CSI-RS.Such as using CSI-RS reference signals, it is necessary to pass through OAM
Or X2/S1 mouthfuls of notice CSI-RS power, and UE being handed down to, UE needs to use the CSI-RS reference signals to carry out the measurement of RSRP etc..
