The eNodeB is used between the UE based on the corresponding MIMO configuration information in the band of position where the UE
MIMO method is communicated.
In the specific implementation process, for downlink transmission, the signal of each RRU can be received based on UE
(Reference Signal Receiving Power, RSRP) value, determines the band of position where UE, can specifically have following
Two ways；
Mode one: the uplink signal based on received UE calculates the downlink RSRP value of UE.
Specifically, eNodeB determines that the step of band of position in the cell after the merging where the UE includes:
It is received for each RRU in the cell after merging, the eNodeB according to the transmission power of the UE and the RRU
The uplink receiving signal strength of the signal of the UE determines uplink loss value, and is based on the uplink loss value, and determining should
Downlink loss value of the RRU to UE transmission signal；According to the transmission power of the RRU and the downlink loss determined
Value, determines that UE receives the Reference Signal Received Power RSRP value of the signal of the RRU；
The eNodeB determines that the UE receives the maximum value in the RSRP value of the signal of each RRU；
If the difference of RSRP value and the maximum value that the UE receives the signal of any RRU is less than or equal to setting thresholding
Value, it is determined that any RRU belongs to the RRU set for covering the band of position where the UE；
It will be in the cell after the merging of all RRU collectively covered where area is determined as the UE in determining RRU set
The band of position.
In this mode, the RRU is subtracted using the transmission power of UE and receives the upper of the UE for each RRU, eNodeB
The uplink receiving signal strength of row signal, obtains uplink loss value；And it is based on transmission loss model and the uplink
Loss value, if calculating downlink loss value of the RRU to UE transmission of downlink signal；It is subtracted really using the transmission power of the RRU
Fixed downlink loss value obtains the RSRP value that UE receives the signal of the RRU.Successively determine that UE receives the letter of each RRU
Number RSRP value, and determine maximum value therein；For the RSRP value of the signal of the received other RRU of UE, by the RSRP value
It is compared with the maximum value, if the difference of the RSRP value and the maximum value is less than or equal to (such as 3 points of setting threshold value
Shellfish (dB)), then a RRU being determined as other RRU in the RRU set of the band of position where covering UE, here,
RRU in RRU set includes the RRU of the corresponding maximum value (difference of the RRU and the maximum value is 0).
Mode two, eNodeB receive the RSRP value that UE is reported；
Specifically, eNodeB determines the band of position in the cell after the merging where the UE, comprising:
The eNodeB receives the Reference Signal Received Power RSRP that each RRU reference signal that the UE is reported reaches the UE
Value；
The eNodeB determines the maximum value in received each RSRP value；
If the difference of the RSRP value for any RRU that the UE is reported and the maximum value is less than or equal to setting threshold value,
Then determine that any RRU belongs to the RRU set for covering the band of position where the UE；
It will be in the cell after the merging of all RRU collectively covered where area is determined as the UE in determining RRU set
The band of position.
In this mode, eNodeB can indicate that UE reaches the downlink RSRP of the UE to each RRU to UE sending measuring list
Value measures, and UE reports the RSRP measured value to RRU.After eNodeB receives the RSRP value for each RRU that UE is reported, subsequent place
Reason process is identical as mode one, and which is not described herein again.

The corresponding MIMO configuration information in a band of position includes the letter of all RRU in the RRU set for cover any one band of position
Breath.
S403: the eNodeB determine need with communicated between UE after, it is small after determining the merging where the UE
The band of position in area.
Here, determine that the process in the position UE region may is that for each RRU, eNodeB is according to the transmitting function of UE
Rate and the RRU receive the uplink receiving signal strength of the signal of the UE, determine uplink loss value, and be based on the uplink
Loss value determines downlink loss value of the RRU to UE transmission signal；Described according to the transmission power of the RRU and determining
Downlink loss value determines that UE receives the Reference Signal Received Power RSRP value of the signal of the RRU；If UE receives any RRU
Signal RSRP value, with UE receive the maximum value in the RSRP value of the signal of each RRU difference be less than or equal to setting door
Limit value, it is determined that any RRU belongs to the RRU set of the band of position where covering UE；All RRU in determining RRU set
The area that collectively covers be the band of position in cell after merging where UE.
S404:eNodeB is according to the corresponding MIMO configuration information in the band of position and each band of position where UE, really
