Description

Collaborative transmission method between a kind of wave beam, apparatus and system
Technical field
The present invention relates to radio communication field, and in particular to collaborative transmission method between a kind of wave beam, device And system.
Background technology
5th Generation Mobile Communication System progressively expands communication spectrum to millimeter wave frequency band.WAP The use of high-density deployment and big bandwidth narrow beam millimeter wave is to solve 5G (5Generation) broadband to pass Defeated technical way, from access point deployment mode, millimeter wave access network has following features：
1) access point dense deployment causes the millimeter wave that diverse access point (identical or different operator) is sent Inter-beam interference chance is big, and cooperation chance is big；2) millimeter wave propagation path loss is big.
The above-mentioned occupation mode of millimeter wave and propagation loss characteristic require that the 5th Generation Mobile Communication System uses wave beam Between cooperative transmission technology between interference coordination technique and wave beam.
Inter-beam interference coordination technique is to existing Inter-Cell Interference Coordination (ICIC：Inter Cell Interference Coordination) technology development, cooperative transmission technology is that existing multiple spot is assisted between wave beam With transmission (CoMP:Coordinated Multi-Point) technology development.
Inter-Cell Interference Coordination technology is interference coordination between the common frequency multi-cell of the implementation on frequency domain.ICIC Basic fundamental be divided into two classes：Partial frequency multiplexing technology (FFR：Fractional Frequency Reuse) With soft-frequency reuse technology (SFR：Soft Frequency Reuse).
Enhanced Inter-Cell Interference Coordination (eICIC:Enhanced Inter Cell Interference Coordination it is) interference coordination between the common frequency multi-cell implemented in time domain, eICIC core thinking is Interference is staggered in time.One or more sub-frame configurations it is " the almost son of blank by macrocell Frame (ABS:Almost Blank SubFrame) ", Microcell is cell-edge terminals in ABS subframes (UE) service is provided, so as to avoid the main interference from macrocell, cell edge UE is improved Service speed.
FeICIC(Further Enhanced Inter Cell Interference Coordination：Further increase Strong Inter-Cell Interference Coordination) it is the enhancing to eICIC technologies, under FeICIC, macro station can be UE special PDCCH (Physical Downlink Control Channel, thing are dispatched in ABS subframes Manage down control channel) or PDSCH (Physical Downlink Shared Channel, physical down Shared channel)；Therefore, in general, in this case, macro station can be with very low transmission power To dispatch the UE that its channel condition is good, to avoid producing interference to micro- station.Now, PDCCH/PDSCH/PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) It can be launched Deng channel with the power of very little, but enable these channels to be decoded reliably again. Macro station can launch the special PDCCH or PDSCH of UE, but precondition is, macro station needs Transmission power is reduced in ABS subframes to reduce the interference to micro- station, and is needed in ABS subframes Transmission power size related signaling tell micro- station.This point is eICIC and FeICIC fundamental difference.
Under FeICIC, macro station can dispatch UE in ABS subframes；Accordingly, with respect to eICIC, FeICIC more effectively can be used in combination with CoMP (multipoint cooperative transmitting/reception).
The transmission rate for being proposed to be lifted cell-edge terminals of multi-point cooperative transmission, be exactly specifically The signal intensity that terminal in lifting fringe region is received.The realization of multi-point cooperative transmission (CoMP) It is that premised on Inter-Cell Interference Coordination, multi-point cooperative transmission must be avoided in multi-point interference In the case of the transmitting diversity realized, (Multiple-Input Multiple-Output, multi input is more by MIMO Output) transmission means.
CS/CB (Coordinated scheduling and beamforming, coordinated scheduling and wave beam forming) It is coordination technique between a kind of wave beam, the technology can dynamically reduce the interference from other cells.UE's Data can only be obtained from service node, and the scheduling of user and wave beam forming are based in CoMP clusters Coordination result between eNodeBs (evolved base station).
Descending CoMP core technology is JPT (Joint processing and transmission, joint Processing and transmission), JPT includes two kinds of implementations：
Dynamic node is selected, according to CSI (Channel State Information, channel condition information), An eNodeB is selected in the eNodeBs for dynamically participating in coordinated emission from cluster to be used to send to UE Data；
Joint is sent, according to CSI, and two are selected in the eNodeBs for dynamically participating in coordinated emission from cluster Individual or multiple eNodeB to UE simultaneously for sending data；
For multiple eNodeB simultaneously for sending data to UE, it is divided into two kinds of situations：Incoherent hair Penetrate and coherent transmitting, the noncoherent transmission typical way is transmitting diversity, the typical case of the coherent transmitting Mode is MIMO transmission.
The shortcoming of prior art is：The inter-beam interference based on beam position or terminal orientation is not supported to coordinate Between wave beam cooperative transmission, the directional information of wave beam or the azimuth information of terminal can not be obtained in real time, and The potential interference relation or potential cooperative transmission relation between diverse access point wave beam can not be determined in real time.
