As shown in Figure 1, RRU (Radio Remote Unit, Remote Radio Unit) provided in an embodiment of the present invention, including：
Anneta module 101, antenna Subarray partition module 102 and radio-frequency module 103, wherein：
Anneta module 101 includes at least two antenna submatrixs, and each antenna submatrix includes at least one antenna oscillator；
Radio-frequency module 103 includes the RF signal receiving and s ending channel identical with antenna submatrix quantity；
Antenna Subarray partition module 102 is used for each antenna oscillator in each antenna submatrix is corresponding with the antenna submatrix
RF signal receiving and s ending channel is connected.
It is by antenna Subarray partition module 102 that each antenna is sub due to being mutiple antennas submatrix by each antenna partition
Each antenna oscillator RF signal receiving and s ending channel corresponding with the antenna submatrix in battle array is connected so that the day in an antenna submatrix
Linear oscillator shares a RF signal receiving and s ending channel, so reducing the number of devices of Remote Radio Unit, reduces extensive
The complexity of mimo system.
Anneta module 101 is used for completing the transmitting and reception of wireless signal.Specifically, as shown in Fig. 2, carry out antenna submatrix
Division when, all antenna oscillators are divided into k groups according to the rule of setting, every group forms a day comprising several antenna oscillators
Line submatrix, i.e. i-th of antenna submatrix include MiA antenna oscillator, entire Anneta module include N number of antenna oscillator (N=M altogether1+M2
+…+Mi+…+Mk)。
Above-mentioned antenna Subarray partition module 102, i.e. feeding network between radio-frequency module and Anneta module, for by radio frequency
Transmitting-receiving letter channel is corresponded with antenna submatrix.Antenna Subarray partition module 102 is in the side being connect with Anneta module 101
N number of interface altogether, Anneta module and antenna Subarray partition module can be separate design or integrated design, they it
Between N number of interface, can be connected by via mode or radio frequency connector mode.Antenna Subarray partition module 102 is with penetrating
The common k interface in side that frequency module 103 connects, can be interconnected by radio frequency connector mode.Antenna Subarray partition module 102 can
To be realized by the power splitter identical with antenna submatrix quantity.

Desired antenna pattern is realized in Anneta module.
Consider that, according to the application scenarios of Massive MIMO base stations, Subarray partition can be from antenna Subarray partition dimension
Vertical direction Subarray partition, horizontal direction Subarray partition or plane Subarray partition.Vertical direction Subarray partition, that is, same day
Each antenna oscillator orientation in line submatrix is each in ground, horizontal direction Subarray partition, that is, same antenna submatrix
Antenna oscillator orientation is parallel to ground, and each antenna oscillator in plane Subarray partition, that is, same antenna submatrix is flat in one
Face.After Subarray partition, antenna element (center of two submatrixs) the center spacing for being equivalent to group battle array becomes larger, in the mistake of wave beam adjustment
Cheng Zhong easily goes out graing lobe, that is, in the case of ensureing same antenna index, adjustable angle range becomes smaller.Bay is adopted in consideration
Which kind of, with the Subarray partition of dimension, can require to consider from the angular range of antenna beam.By taking macro base station as an example, due to base station
Highly much smaller than base station covering radius, therefore it is required that the angle of coverage of vertical dimensions is smaller, and in the angle of coverage of horizontal dimensions
It is larger.Therefore, preferably with vertical direction Subarray partition, ensure that horizontal direction has enough degree of freedom.It is tieed up in this way in level
Degree, antenna beam is adjustable in the range of larger angle.

Linear oscillator (N=M1+M2+…+Mi+…+Mk), it is divided equally into k antenna submatrix, the antenna oscillator number in each antenna submatrix
Measure equal, i.e. M1=M2=...=Mi=...=Mk=M meets N=M*k, and the antenna oscillator in each antenna submatrix has
Identical spread pattern.Correspondingly, in antenna Subarray partition module, connect from the interface of radio-frequency module side k to Anneta module side is N number of
The feeding network of mouth is that constant power distributes.
Subarray partition is not irregularly overlapped, specific method is the N number of antenna oscillator (N=M for being included Anneta module1+
M2+…+Mi+…+Mk), irregular to be divided into k antenna submatrix, the antenna oscillator number that each antenna submatrix includes can
Difference, and the spread pattern of the antenna oscillator of each antenna submatrix can also be different.Correspondingly, antenna Subarray partition module
In, it is distributed from the interface of radio-frequency module side k to the feeding network of the N number of interface in Anneta module side for unequal power.It does not weigh irregularly
Folded subarray configuration destroys the periodicity of array beams, can be good at reducing the influence of graing lobe, grid zero.
Rule overlapping Subarray partition, specific method is by antenna oscillator N number of included in Anneta module, is regularly divided
For k antenna submatrix, the antenna oscillator quantity in each antenna submatrix is equal, i.e. M1=M2=...=Mi=...=Mk=M, and
Each submatrix has same shape, but same antenna oscillator can be divided into different antenna submatrixs, and array element, which is repeated, to be made
With, i.e., be to be overlapped between submatrix, i.e. M*k>N.Rule overlapping submatrix increases under the conditions of submatrix center-spaced is not increased
Submatrix aperture will not increase graing lobe quantity, and the secondary lobe of directional diagram can be forced down by the method for density or amplitude weighting, increase
The flexibility of wave beam is added.
Remote Radio Unit provided in an embodiment of the present invention, penetrating in reduction Massive MIMO base stations that can be by a relatively large margin
Frequency transmitting-receiving letter number of channels reduces the complexity of system on hardware view.Meanwhile it is assigned according to the wave beam of the application scenarios of base station
Shape requirement, selects different antenna Subarray partition schemes, can greatly improve the spirit of Massive MIMO base station wave beam formings
