Under super cell, combine the radio frequency resource of each single cell, to dispatch the TM9 of more numbers of plies.Specifically basis
The combination of different CSI-RS port, generating corresponding PMI, (Precoding Matrix Indicator, pre-coding matrix refer to
Show) code book, and be distributed to each prevention at radio-frequency port and send, it is received by terminal.
Particular by every group of physical port (certain more physical antenna port or RRU (the Radio Remote of base station side cell
Unit, Remote Radio Unit) under antenna combination) receive the signal strength of some terminal, to identify this terminal whether should be
Current radio frequency port activation, subsequent carry out receiving and transmitting signal.
The CQI (Channel Quality Indicator, quality of wireless channel) and present flow rate reported according to terminal
(default refers to downlink traffic, and Uplink MIMO is similarly), base station end (default terminal to support to determine whether terminal needs to be switched to TM9
TM9), the RI (Rank Indication, order instruction) that then base station end is reported according to terminal in TM9, determines whether terminal protects
Hold TM9 scheduling.However terminal to be reported at TM9 RI >=3, it is necessary to guarantee terminal in CSI-RS (Channel State
Information-Reference Signals, channel state information reference signals) subframe is capable of measuring multiple CSI-RS
Port, and it is mutually orthogonal.Provide that the CSI-RS port that 4 layers of TM9 are used is { 15,16,17,18 } in 3GPP TS 36.213,
The CSI-RS port that 8 layers of TM9 are used is { 15,16,17,18,19,20,21,22 }, i.e. base station end must all issue 4 layers or 8
CSI-RS port required for layer.
One, the super cell of 2 antennas
For the cell of 2 antennas, the CSI-RS port combination that base station end can configure has { 15,16 } and { 17,18 }, surpasses
It is any can to configure the two for former cell each of under grade cell (being formed by multiple cell combinations, United Dispatching time-frequency domain resources)
One combination, for example there are three former cell combinations into super cell, the CSI-RS port of former cell 1 is configured to { 15,16 }, former
The CSI-RS port of cell 2 is configured to { 17,18 }, and the CSI-RS port of former cell 3 is configured to { 15,16 }, then this is super
The CSI-RS port configuration set of cell is { 15,16,17,18 }.When the mobile friendship in former cell 1 and former cell 2 of some terminal
When the overlapping region of folded region or former cell 2 and former cell 3, the CSI-RS port collection that this terminal can receive be combined into 15,16,
17,18 }, then base station can allow this terminal to attempt scheduling TM9 mode, if this terminal reports RI to stablize at 3 or 4, that
It is one times more intimate than the gain of TM3 under 2 antenna cells of scheduling.If certain terminal is moved to the friendship of former cell 1 and former cell 3
When folded region, since the collection of receivable CSI-RS port signal is combined into { 15,16 }, base station end can keep this terminal at TM3
Scheduling, and more no gain before, certain base station end can also allow this terminal scheduling TM9 2*2MIMO, but due to 2 antennas
TM9 2*2MIMO than the TM3 2*2MIMO of 2 antennas need base station interface-free resources increase CSI-RS port transmission, occupy
RB resource, therefore generally terminal will not be allowed in this scene switching to TM9.
Usual deployment scenario, multiple CP overlapping coverage areas and the single overlay area CP.
As shown in Fig. 3, in multiple CP overlapping coverage areas, user is located at the overlapping region of two CP while can receive
To multiple port downlink signals are combined, (it is { 15,16 } that former cell 1, which configures CSI-RS port, and former cell 2 configures CSI-RS port
For { 17,18 }), in the case where channel condition meets, maximum achievable downlink TM9 combines multiport MIMO, to mention to user
For higher downlink traffic.
As shown in Fig. 4, in single CP overlapping coverage area, for the single overlay area CP user UE1 and
UE2, due to being only capable of receiving the port signal of single CP, CSI-RS port is { 15,16 } or { 17,18 }, can not be combined
The gain of multiport.If certain UE is under the super cell that identical one group of CSI-RS port is configured, even if small in multiple originals
The overlapping region in area, since terminal can only receive two CSI-RS port, even if base station allows terminal to be switched to TM9 scheduling,
Downlink traffic gain cannot be brought.
Two, the super cell of 4 antennas
For the cell of 4 antennas, guaranteeing that former cell can dispatch 4 layers of MIMO of TM9 (CSI-RS port couple in single cell
The PMI that answers needs orthogonal) under the premise of, the CSI-RS port combination that can be configured have { 15,17,19,21 } and 16,18,20,
22 }, the receivable CSI-RS port collection of super cell overlapping region of two former cell combinations be combined into 15,16,17,18,19,
20,21,22 }, schedulable TM9 8*8MIMO, in former cell receivable CSI-RS port collection be combined into { 15,17,19,21 } or
{ 16,18,20,22 }, schedulable TM9 8*4MIMO.
It is important that other combinations it cannot be guaranteed that 4 antenna original Intra-cell PMI orthogonality, for example former cell 1 configures
CSI-RS port is { 15,16,17,18 }, and the CSI-RS port that former cell 2 configures is { 19,20,21,22 }, even if two small
Area's overlapping region can satisfy TM9 8*8MIMO, but former Intra-cell { 15,16,17,18 } or { 19,20,21,22 } is corresponding
PMI is non-orthogonal, i.e., cannot dispatch TM9 8*4MIMO.
4 antenna original cells both can configure any one combination each of under super cell, then super cell can be with
Signal is sent as 8 antennas, the collection of CSI-RS port configuration is combined into { 15,16,17,18,19,20,21,22 }, when some
Terminal is mobile can to dispatch TM9 8*4MIMO in some former cell area, when it is mobile be combined into collection 15,16,17,18,
When two or more former cell overlapping regions 19,20,21,22 }, so that it may be switched to 8*n MIMO, 4≤n≤8, n according to
Terminal is determined in the RI that overlapping region reports.
It is 4port below for CSI-RS, is fed back to obtain PMI code book according to UE are as follows:
When former cell 1 configuration CSI-RS port group is combined into { 15,16 }, the radio-frequency module of this cell only needs to send square
Battle array front two row weight；When former cell 2 is configured to { 17,18 }, the radio-frequency module of this cell only needs two rows after sending metrix to weigh
Value.Terminal in two cell overlapping regions, so that it may which the collection for receiving CSI-RS port is combined into { 15,16,17,18 }.
When CSI-RS is configured to 8port, need to be adjusted PMI matrix, i.e., { 15,17,19,21 } and 16,18,
20,22 }, corresponding weight is sent according to the CSI-RS Port configuration of single former cell.Guarantee that overlapping region maximum can dispatch
TM9 8*8MIMO, single original Intra-cell can dispatch TM9 8*4MIMO.
This ensures that base station decides whether that this terminal can be adjusted according to the RI that it is reported when dispatching some terminal
Spend TM9 multilayer transmission.
Since super cell is formed by the multiple cell combinations of tradition, the radio frequency resource of each conventional cell can be unified to adjust
Degree, the antenna number for being equivalent to super cell is the sum of the antenna number of multiple combination cells.So super cell can dispatch
The data flow number of plies will be more or even double than conventional cell.Under the premise of network disposes super cell, by software
Algorithm process is realized distributed MIMO (Multiple-Input Multiple-Output, multiple-input and multiple-output) scheduling, and is led to
It crosses actual network deployment to optimize and revise, allows multiple radio-frequency antennas that can cooperate with transmitting and receiving data, do not increasing physical network
In the case where equipment, so that it may which the handling capacity for improving subzone network reaches portfolio and increases income.
The scheme provided according to embodiments of the present invention combines the TM9 that multiple radio frequency resources dispatch more numbers of plies, fewer than the number of plies
When flow it is bigger, cell throughout is more.
Although describing the invention in detail above, but the invention is not restricted to this, those skilled in the art of the present technique
It can be carry out various modifications with principle according to the present invention.Therefore, all to be modified according to made by the principle of the invention, all it should be understood as
Fall into protection scope of the present invention.
