Each large operator wants to generate more throughput in a limited network deployment. However, in the conventional deployment, after the number of logical antenna ports in the same cell is fixed, the maximum throughput that can be generated is basically fixed (related to the transmission mode and the number of layers). For example, in an LTE (Long Term Evolution) wireless system, the number of data stream layers that can only be scheduled by a 2-antenna cell is at most 4, and the number of data stream layers that can only be scheduled by a 4-antenna cell is at most 4. The more layers of data streams, the larger the throughput basically, but the number of layers is completely limited by the number of logical antenna ports.

Under the super cell, the radio frequency resources of each single cell are combined to schedule more layers of TM9. Specifically, according to the combination of different CSI-RS ports, a corresponding PMI (Precoding Matrix Indicator) codebook is generated and distributed to each rf port for transmission and reception by the terminal.
Specifically, each group of physical ports (a certain multiple physical antenna port or an antenna combination under a Radio Remote Unit (RRU)) of a cell on the base station side receives the signal strength of a certain terminal, so as to identify whether the terminal should be activated at the current Radio frequency port, and subsequently transmit and receive signals.
According to the CQI (Channel Quality Indicator, radio Channel Quality) reported by the terminal and the current traffic (default refers to downlink traffic and uplink MIMO, the same applies), the base station determines whether the terminal needs to switch to TM9 (the default terminal supports TM 9), and then the base station determines whether the terminal keeps TM9 scheduling according to the RI (Rank Indication ) reported by the terminal when the terminal is in TM9. However, to report RI > =3 in TM9, it is necessary to ensure that the terminal can measure multiple CSI-RS ports in CSI-RS (Channel State Information-Reference Signals) subframes and be orthogonal to each other. The 3GPP TS 36.213 specifies that the CSI-RS port used by the 4-layer TM9 is {15,16,17,18}, and the CSI-RS port used by the 8-layer TM9 is {15,16,17,18,19,20,21,22}, i.e., the base station must send all the CSI-RS ports required by the 4-layer or 8-layer.
1. 2 super cell of antenna
For a 2-antenna cell, the CSI-RS port combinations that can be configured by the base station side include {15,16} and {17,18}, each original cell under a super cell (formed by combining a plurality of cells and scheduling time-frequency-domain resources in a unified manner) can configure any combination of the two, for example, three original cells are combined into a super cell, the CSI-RS port of the original cell 1 is configured as {15,16}, the CSI-RS port of the original cell 2 is configured as {17,18}, the CSI-RS port of the original cell 3 is configured as {15,16}, and then the CSI-RS port configuration set of the super cell is {15,16,17,18}. When a terminal moves in the overlapping area of the original cell 1 and the original cell 2 or the overlapping area of the original cell 2 and the original cell 3, the CSI-RS port set that the terminal can receive is {15,16,17,18}, then the base station can let the terminal try to schedule the TM9 mode, and if the terminal reports that the RI is stable at 3 or 4, it has approximately one time gain than the TM3 under the scheduling 2 antenna cell. Certainly, if a terminal moves to an overlapping area of an original cell 1 and an original cell 3, because the set of the receivable CSI-RS port signals is {15,16}, the base station end can keep the terminal scheduled under TM3, and there is no gain compared with the previous one, and certainly the base station end can also let the terminal schedule TM9 × 2mimo, but because TM9 × 2mimo with 2 antennas needs the base station to increase the sending of the CSI-RS port at the air interface resources compared with TM3 × 2mimo with 2 antennas, RB resources are occupied, the terminal is generally not allowed to switch to TM9 in this scenario.
Common deployment scenarios, multiple CPs overlap coverage areas and a single CP coverage area.
As shown in fig. 3, in the overlapping coverage area of multiple CPs, a user located in the overlapping area of two CPs can receive downlink signals combining multiple ports (CSI-RS port configured by the original cell 1 is {15,16}, CSI-RS port configured by the original cell 2 is {17,18 }), and can maximally implement downlink TM9 combined multi-port MIMO under the condition that channel conditions are satisfied, thereby providing higher downlink traffic for the user.
As shown in FIG. 4, in a single CP overlapping coverage area, for UE1 and UE2 of users in the single CP coverage area, since only port signals of a single CP can be received, CSI-RS ports are {15,16} or {17,18}, and thus, the gain of joint multi-port cannot be obtained. Certainly, if the UE is in a super cell configured by the same group of CSI-RS ports, even in an overlapping area of multiple original cells, since the terminal can only receive two CSI-RS ports, even if the base station switches the terminal to TM9 scheduling, it cannot bring downlink traffic gain.
2. 4-antenna super cell
Aiming at a 4-antenna cell, under the premise of ensuring that an original cell can schedule TM9 4-layer MIMO (PMI corresponding to CSI-RS ports in a single cell needs to be orthogonal), configurable CSI-RS ports are combined into {15,17,19,21} and {16,18,20,22}, a set of CSI-RS ports receivable in a super cell overlapping region of two original cell combinations is {15,16,17,18,19,20,21,22}, the adjustable TM9 x 8MIMO, and a set of CSI-RS ports receivable in the original cell is {15,17,19,21} or {16,18,20,22}, and the adjustable TM9 x 4MIMO.
It is important that other combinations cannot guarantee the orthogonality of PMIs inside the 4-antenna original cell, for example, CSI-RS port configured by original cell 1 is {15,16,17,18}, CSI-RS port configured by original cell 2 is {19,20,21,22}, even though the overlapping region of two cells can satisfy TM9 × 8mimo, PMIs corresponding to {15,16,17,18} or {19,20,21,22} inside the original cell are not orthogonal, i.e., TM9 × 8mimo 4 cannot be scheduled.
Each 4-antenna original cell under the super cell can be configured with any combination of the two, so the super cell can be used as 8 antennas to transmit signals, the set of CSI-RS port configurations is {15,16,17,18,19,20,21,22}, when a certain terminal moves in a certain original cell region, TM9 x 4MIMO can be scheduled, and when a certain terminal moves in an overlapping region of two or more original cells of {15,16,17,18,19,20,21,22}, the super cell can be switched to 8 x n MIMO,4< = n < =8, n according to the RI decision reported by the terminal in the overlapping region.
The following PMI codebook obtained according to the UE feedback for CSI-RS as 4port is:
when the original cell 1 is configured with a CSI-RS port combination of {15,16}, the radio frequency module of the cell only needs to send the first two rows of matrix weights; when the original cell 2 is configured as {17,18}, the rf module of this cell only needs to transmit two rows of weights after the matrix. A terminal in the overlapping area of two cells can receive the CSI-RS port set as 15,16,17, 18.
When the CSI-RS is configured to be 8 ports, the PMI matrix needs to be adjusted, namely {15,17,19,21} and {16,18,20,22}, and corresponding weights are sent according to the CSI-RS Port configuration of a single original cell. And ensuring that the maximum overlapping region can schedule TM 9X 8MIMO, and the interior of a single original cell can schedule TM 9X 4MIMO.
Thus, when a base station schedules a certain terminal, the base station can determine whether the terminal can schedule TM9 multi-layer transmission according to the RI reported by the base station.
Because the super cell is formed by combining a plurality of traditional cells, the radio frequency resource of each traditional cell can be uniformly scheduled, which is equivalent to the sum of the number of antennas of the super cell and the number of antennas of a plurality of combined cells. The number of data stream layers that can be scheduled by the super cell is larger than that of the conventional cell, and even doubles. On the premise that a super cell is deployed in a network, distributed MIMO (Multiple-Input Multiple-Output) scheduling is realized through algorithm processing on software, and Multiple radio frequency antennas can cooperatively send and receive data through actual network deployment optimization adjustment, so that the throughput of a cell network can be improved under the condition that physical network equipment is not increased, and the increase of the traffic volume is achieved.
According to the scheme provided by the embodiment of the invention, TM9 with more layers is scheduled by combining a plurality of radio frequency resources, and compared with the condition that the number of the layers is less, the flow is larger, and the cell throughput is more.
Although the present invention has been described in detail, the present invention is not limited thereto, and those skilled in the art can make various modifications according to the principle of the present invention. Thus, modifications made in accordance with the principles of the present invention should be understood to fall within the scope of the present invention.
