Specific embodiment
It is more fully described the exemplary embodiment of the disclosure below with reference to accompanying drawings.Although showing in accompanying drawing
The exemplary embodiment of the disclosure it being understood, however, that may be realized in various forms the disclosure and should be by
Embodiments set forth here is limited.On the contrary, these embodiments are provided to be able to be best understood from this
Open, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Full dimension multiple-input and multiple-output FD-MIMO is based primarily upon two-dimensional antenna array (multiple skies of same row
Linear array is connected to multiple transceiver channels), as shown in Fig. 2 wherein, physical antenna array 1 and transceiver channel
2 is all two-dimensional array.The power that two-dimensional antenna array each transceiver channel corresponding of FD-MIMO is supported is big
Little is consistent, and for example the total transmission power of FD-MIMO base station is 40W, has 64 passages, typically
For each channel power be (40/64) W.
The two-dimensional antenna array adopting with regard to FD-MIMO in 3GPP at present can be described with following parameter
(M, N, P, M_TXRU), wherein M represent a period of time number of a like-polarized array antenna, and N represents antenna array
The columns of row, P=2 represents and adopts dual polarized antenna, M_TXRU represents the corresponding transmitting-receiving of same row antenna element
The number of passage, a transceiver channel may correspond to several antenna element, and Q=2N*M_TXRU represents
Transceiver channel sum in this aerial array corresponding transceiver channel array.For example, aerial array (M, N, P,
M_TXRU)=(8,4,2,4) corresponding transceiver channel sum Q is 32.
Specifically, the physical antenna array of two-dimensional antenna array and transceiver channel array are all two-dimentional, often
Individual physical antenna a period of time corresponds to a transceiver channel, so not only between multiple physical antenna a period of time of level dimension
Phase difference can adjust, and the phase difference between multiple physical antenna a period of time of vertical dimension can also adjust,
FD-MIMO can not only carry out wave beam forming in level dimension, and can carry out wave beam forming in vertical dimension.Though
So FD-MIMO can form narrower business beam and can make maximum wave beam in vertical dimension adjustment direction
User is pointed in direction, but for broadcast beam, due to cell specific reference signal CRS, physical down control
The common control signals such as channel PDCCH processed depend on broadcast beam, different high in order to cover this cell as far as possible
The user of degree, FD-MIMO needs to form wider broadcast beam.In addition, TM2 in transmission mode,
TM3 etc. relies on the transmission mode that CRS is demodulated also can be affected by broadcast beam gain.
FD-MIMO typically forms broadcast beam by broadcasting shape-endowing weight value, in general, each antenna list
The beam angle of unit is wider (typically have 65 degree, 90 degree etc.), and therefore, two-dimensional antenna array to be allowed is formed
Broadcast beam, its broadcast shape-endowing weight value can introduce certain power loss, and antenna element number is more, Ke Nengyin
The power loss entering is bigger.With the horizontal 3dB width of individual antenna beam of unit and vertical 3dB width it is all
As a example 65 degree, for the 64TXRU aerial array for (M, N, P, M_TXRU)=(8,4,2,64), if will
Form about 60 degree of horizontal broadcast beam and about 60 degree of vertical broadcast beam, broadcast weight value can bring larger
Weights loss, for example with signal amplitude weights Am=[0.45,1,1,0.53] of horizontal broadcast beam, phase place
Pm=[120,149,156,328], the signal amplitude weights of vertical broadcast beam are
Am=[0.45,1,0.9,0.4,0.9,1,0.45], phase place Pm=[0,90,165, -120, -190,175,90, -10], water
The weights loss that the signal amplitude weights of flat broadcast beam lead to is about -2.07dB, the signal of vertical broadcast beam
The weights loss that amplitude weights lead to is about -2.65dB, and total weights loss is about -4.72dB.
Broadcast shape-endowing weight value weights loss can lead to reduce broadcast beam gain, thus reduce CRS,
The covering performance of the common control signals such as PDCCH, in addition, TM2, TM3 etc. rely on CRS to be demodulated
Transmission mode also can be affected.
