Description

Method, device and storage medium for resisting sudden interference fluctuation of adjacent cells

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a storage medium for resisting sudden interference fluctuation in a neighboring cell.

Background

In a hot spot high-capacity scene, a wireless network environment is complex and interference is variable, and when networking is performed, although the utilization rate of wireless resources and the spectrum efficiency can be improved through base station ultra-dense networking, many problems are brought at the same time.

For example, in ultra-dense networking, co-channel interference becomes more and more severe as distances between low-power nodes become closer and closer due to deployment of a large number of unplanned low-power wireless access points. Although the inter-cell interference can be reduced through power control, as cells are deployed more and more densely, the cells are deployed with a randomized distribution, so that the interference relationship in a shorter distance ultra-dense networking scenario becomes more complex than an ultra-dense networking scenario.

In a shorter distance ultra-dense network, one cell is often interfered by several interference sources in surrounding cells, including interference from macro base stations and interference from surrounding small base stations. Interference from multiple cells in the network needs to be considered when designing an interference management scheme. The interference can be reduced to a certain extent by adopting joint resource allocation and interference alignment as much as possible in time domain, frequency domain and space domain through joint resource scheduling among multiple cells.

With shorter distance ultra-dense cell deployments, as the distance between low power nodes gets closer and closer, the cell radius becomes smaller and the inter-cell handovers are too frequent as users move between cells. When there are only a few users in a cell, all users can maintain a high transmission rate due to the close radio transmission distance. However, when a user suddenly arrives in a neighboring cell or leaves the neighboring cell, the data transmission rate will change, and the interference of the neighboring cell will fluctuate obviously.

In addition, as the distance between low-power nodes is closer and closer, the network deployment density is increased, and the network energy consumption is increased. Although energy can be saved and energy efficiency can be improved by the cell dynamic turn-off/turn-on strategy. However, since the turn-off and turn-on of the neighboring cells require long configuration and scheduling time, the interference of the neighboring cells may also fluctuate significantly.

Furthermore, the number of users served in each cell becomes smaller due to the closer distance between the low power nodes. For example, when each cell may have only a few users, sometimes or no users serving them, frequent bursty data accesses by users of neighboring cells may also cause fluctuations in interference signals to neighboring cells.

The SINR measured value of the current cell user is obtained by calculating the ratio of the energy of the downlink reference signal of the current cell to the energy of the received interference signal of the adjacent cell to the noise sum of the cell. Namely:

SINR-current cell measurement reference signal energy/(neighbor cell interference signal energy + current cell noise signal energy).

And because the calculation of the CQI is obtained based on the SINR measurement value, the SINR measurement value of the user in the current cell may fluctuate due to the fluctuation of the interference of the neighboring cell, which may cause the CQI measured by the user terminal in the current cell based on the current subframe to fluctuate. Meanwhile, the communication delay between the base station of the current cell and the user is reduced when the cell becomes small, the user side detects that the CQI is fed back to the base station through the uplink channel and is the CQI of the channel of the previous subframe, the current channel quality cannot be reflected in real time, the traditional scheduling algorithm based on the CQI is inaccurate, and network oscillation is caused.

In view of this, reducing the bursty interference fluctuation between adjacent areas in a shorter-distance ultra-dense network is a technical problem to be solved urgently.

Detailed Description

The embodiment of the invention provides a method, a device and a storage medium for resisting sudden interference fluctuation of an adjacent region, and aims to solve the technical problem that the sudden interference fluctuation of the adjacent region is larger in a shorter-distance ultra-dense network in the prior art.

In order to solve the technical problems, the general idea of the embodiment of the present application is as follows:

the method for resisting the sudden interference fluctuation of the adjacent cell is applied to a local data center in a shorter-distance ultra-dense network, wherein the local data center is connected between a local control center and a micro base station, and comprises the following steps: measuring the idle time of a link layer data cache queue of each cell governed by each micro base station in a service area of a local control center; when a first cell generates interference to an adjacent cell in a service area, based on a first idle time corresponding to the first cell, sending first indication information to a first micro base station corresponding to the first cell, wherein the first indication information is used for indicating the first micro base station to execute a setting operation to the first cell, so that the first cell reduces sudden interference fluctuation to the adjacent cell.

In the scheme, the idle time of the link layer data cache queue of each cell governed by each micro base station in the service area of the local control center is measured; when a first cell generates interference to adjacent cells in a service area, based on a first idle time corresponding to the first cell, sending first indication information to a first micro base station corresponding to the first cell, wherein the first indication information is used for indicating the first micro base station to execute a setting operation on the first cell, so that the first cell reduces the generation of sudden interference fluctuation to the adjacent cells, and the sudden interference fluctuation generated between the cells in a shorter-distance ultra-dense network is reduced.

In order to better understand the technical solutions of the present invention, the following detailed descriptions of the technical solutions of the present invention are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the examples of the present invention are the detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the examples of the present invention may be combined with each other without conflict.

Referring to fig. 1, an embodiment of the present invention provides a method for resisting sudden interference fluctuation of a neighboring cell, which is applied to a local data center in a shorter-distance ultra-dense network, where the local data center is connected between a local control center and a micro base station, and a processing procedure of the method is as follows.

Step 101: and measuring the idle time of a link layer data cache queue of each cell governed by each micro base station in the service area of the local control center.

Step 102: when a first cell generates interference to an adjacent cell in a service area, based on a first idle time corresponding to the first cell, sending first indication information to a first micro base station corresponding to the first cell, wherein the first indication information is used for indicating the first micro base station to execute a setting operation to the first cell, so that the first cell reduces sudden interference fluctuation to the adjacent cell.

It should be noted that in the embodiments provided in the present invention, the first cell may be any cell within the service area of the local control center, and should not be understood as a specific cell or specific cells within the service area.

In the embodiment provided by the present invention, when the first idle duration is less than the set threshold, the setting operation is to send the random symbol as data to the first user terminal in the first cell when no data is sent.

Fig. 2 is a diagram of an architecture of a shorter distance ultra-dense network according to an embodiment of the present invention.

In the shorter distance ultra-dense network of fig. 2, a local control center, a local data center, a plurality of micro base stations, and a user terminal communicating with the micro base stations are included.

The local control center is used for transmitting control plane data of a plurality of cells, and is carried by a Centralized Unit (CU). Its main functions include: radio Resource Management (RRM) for multi-cell association, heterogeneous coordination, Quality of Service (QoS) guarantee, cell mobility Management, local Radio link control, and the like.

The local data center is used for transmitting user plane data of a plurality of cells, and is carried by a Distributed Unit (DU). Its main functions include: the data center is provided with a plurality of link layer data buffer queues, wherein each link layer data buffer queue corresponds to a cell service data, and whether a user corresponding to a cell has a user plane data service can be detected by detecting the link layer data buffer queues.

For example, in fig. 2, the link layer buffer queue corresponding to the cell 1 is the buffer queue 1, the link layer buffer queue corresponding to the cell 2 is the buffer queue 2, and the link layer buffer queue corresponding to the cell 3 is the buffer queue 3. The local data center detects the idle states of the buffer queue 1, the buffer queue 2 and the buffer queue 3, and then can know whether the corresponding cell has user plane service data to be transmitted. When a certain buffer queue is detected to be in an idle state, timing can be carried out on the buffer queue until the buffer queue is in a non-idle state, and the current timed duration can be read at any time in the process of timing the idle state of the buffer queue, so that the idle duration of the buffer queue can be obtained.

Assuming that idle time lengths corresponding to the buffer queue 1, the buffer queue 2 and the buffer queue 3 are sequentially recorded as idle time length 1, idle time length 2 and idle time length 3, before the cell 1 is idle, interference is not generated on an adjacent cell, before the cell 2 and the cell 3 are idle, interference is generated on the adjacent cell, the idle time length 1 and the idle time length 2 are both smaller than a set threshold, and the idle time length 3 is larger than the set threshold.

Because the cell 2 generates interference to the adjacent cell before being idle, and the idle time 2 corresponding to the cell 2 is less than the set threshold, the local data center sends the first indication information to the micro base station (i.e. the first micro base station) where the cell 2 (i.e. the first cell) is located, so that the micro base station sends the random symbol as data to the first user terminal in the cell 2 when no data is sent, thereby keeping the cell 2 continuously generating interference to the adjacent cell, keeping the measured value of the signal quality measured by the user terminal of the adjacent cell unchanged, and reducing the occurrence of sudden interference fluctuation between cells in a shorter-distance ultra-dense network.

It should be noted that, in fig. 2, one micro base station only shows one cell, and does not represent that only one cell is served by one micro base station, and actually, there are multiple cells served by one micro base station. Cell 1 to cell 3 may all be referred to as a first cell. In a shorter distance ultra-dense network, the distance between micro base stations is shorter than the distance between micro base stations in the ultra-dense network.

In the embodiment provided by the invention, the setting operation is that when no data is sent, a random symbol is sent to a first user terminal in a first cell as data, after the setting operation is executed, a local data center can receive signal quality measurement information obtained by measuring the signal quality of the first cell and reported by a second micro base station corresponding to an adjacent cell, and the signal quality measurement information is forwarded to a local control center, so that the local control center performs multi-cell joint resource allocation on the cells in a service cell, and therefore, the resources of each cell are orthogonal as much as possible to avoid interference, and for the cells without the orthogonal resource allocation, joint precoding and interference alignment are adopted to inhibit the interference among the cells; and the signal quality measurement information is reported to the second micro base station by the second user terminal in the adjacent cell.

For example, still taking the cell 2 in fig. 2 as an example, after the local data center sends the first indication information to the micro base station (i.e., the first micro base station) corresponding to the cell 2 (i.e., the first cell), the micro base station sends a random symbol to the first user terminal in the cell 2. After measuring the signal quality of the cell 2, the second user terminals in the adjacent cells (i.e., the cell 1 and the cell 3 in fig. 2) of the cell 2 send the measurement results (i.e., signal quality measurement information) to the respective corresponding second micro base stations, and the second micro base stations send the measurement results to the local control center, so that the local data center forwards the signal quality measurement information reported by the respective second user terminals to the local control center, and the local control center performs multi-cell joint resource allocation on the cells in the service area, so as to form a neighboring cell interference suppression signal shown in fig. 2 between the cells, thereby reducing the occurrence of bursty interference fluctuation between the cells in the shorter-distance ultra-dense network.

In the embodiment provided by the present invention, the first micro base station and the second micro base station are the same micro base station or different micro base stations.

For example, assuming that the first cell is cell 2 and its neighboring cells are cell 1, cell 3, and cell 5, where cell 2 and cell 5 are located under micro base station 2, cell 1 is located under micro base station 1, and cell 3 is located under micro base station 1, the micro base station corresponding to cell 1 is micro base station 2, micro base station 2 is a first micro base station, and cell 1, cell 3, and cell 5 are all neighboring cells of cell 2, so their respective corresponding micro base stations are second micro base stations.

It can be seen that, when the first cell (e.g. cell 1) and the neighboring cell (cell 5) are under the same micro base station, the first micro base station and the second micro base station are the same micro base station, and when the first cell (e.g. cell 1) and the neighboring cell (cell 1, cell 3) are under different micro base stations, the first micro base station and the second micro base station are different micro base stations.

In the embodiment provided by the invention, after the local data center forwards the signal quality measurement information to the local control center, the local control center receives the second indication information for performing joint resource allocation on the multiple cells, and forwards the second indication information to all micro base stations in the service area of the local control center.

For example, still taking the example of fig. 2 as an example, after the local control center performs multi-cell joint resource allocation on the cells in the service area, the second indication information for performing joint resource allocation on the multi-cells is sent to the local data center, and the local data center forwards the second indication information to all the micro base stations in the service area of the local control center, so that the micro base stations perform resource allocation according to the second indication information, so that the interference signal for suppressing the neighboring cell as shown in fig. 2 can be formed between the cells, thereby reducing the occurrence of sudden interference fluctuation between the cells in the shorter-distance ultra-dense network.

In an embodiment provided by the present invention, the signal quality measurement information includes:

channel State Information (CSI), Channel Quality Indicator (CQI), Rank Indication Information (RI), Signal to Interference plus Noise Ratio (SINR), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal strength Indication (Received Signal strength Indication), RSSI, block error rate, Hybrid Automatic Repeat Request (HARQ) Information, or a combination thereof.

In the embodiment provided by the invention, when the first idle duration is greater than or equal to the set threshold, the setting operation is to silence the first cell.

In the embodiment provided by the invention, when the setting operation is the silent first cell, the first micro base station is reported to the local control center after the setting operation is executed.

Still taking fig. 2 as an example, if the idle duration 3 (i.e., the first idle duration) corresponding to the cell 3 (i.e., the first cell) is greater than the set threshold, it indicates that there is no service data to be sent for a long time in the cell 3, and at this time, the local data center notifies the micro base station (i.e., the first micro base station) corresponding to the cell 3 to silence the cell 3, and reports the micro base station including the cell 3 in the governed cell to the local control center, so that the local control center performs record management on the micro base station.

After introducing the method for resisting the sudden interference fluctuation of the adjacent cell from the local data center side, introducing the method from the first micro base station side, specifically as follows:

based on the same inventive concept, an embodiment of the present invention provides a method for resisting sudden interference fluctuation of an adjacent cell, which is applied to a first micro base station in a shorter-distance ultra-dense network, where a local data center is connected between a local control center and the first micro base station, as shown in fig. 3, and the method includes:

step 301: receiving first indication information sent by a local data center; the first indication information is generated by the local data center based on a first idle duration of a link layer data cache queue corresponding to a first cell when the first cell is determined to generate interference to an adjacent cell in a service area of the local control center.

Step 302: and according to the first indication information, performing setting operation on the first cell to enable the first cell to reduce sudden interference fluctuation generated on adjacent cells.

In the embodiment provided by the present invention, the setting operation is to send the random symbol as data to the first user terminal in the first cell when no data is sent; and the random symbol is sent when the first idle time length is less than a set threshold value and the first indication information indicates that no data is sent.

For example, taking the micro base station (i.e. the first micro base station) corresponding to the cell 2 (i.e. the first cell) in fig. 2 as an example, after the micro base station corresponding to the cell 2 receives the first indication information sent by the local data center, according to the first indication information, a setting operation is performed on the first cell, where the setting operation is to send a random symbol as data to the first user terminal in the cell 2 when the first base station has no data to send, so that the cell 2 can reduce the occurrence of sudden interference fluctuation on the adjacent cell; and the random symbol is sent when the first idle time length is less than a set threshold value and the first indication information indicates that no data is sent.

In the embodiment provided by the present invention, after sending the random symbol as data to the first user terminal in the first cell, if the first cell and the neighboring cell are located under the same micro base station, the method further includes:

and receiving signal quality measurement information which is sent by a second user terminal in an adjacent cell and is obtained by measuring the signal quality of the first cell.

And sending the signal quality measurement information to a local data center, so that the local data center forwards the signal quality measurement information to a local control center, and then the local control center performs multi-cell joint resource allocation on the cells in the service area.

It should be noted that, if the first cell and the adjacent cell are located under different micro base stations, the second micro base station corresponding to the adjacent cell receives signal quality measurement information, which is sent by the second user terminal in the adjacent cell and is used for measuring the signal quality of the first cell, and forwards the local data to the local control center for multi-cell joint resource allocation.

In the embodiment provided by the present invention, the setting operation may also be muting the first cell; and when the first idle time length is greater than or equal to the set threshold, the first indication information indicates to silence the first cell.

For example, in fig. 2, if it is determined that the idle duration 2 (i.e., the first idle duration) of the buffer queue 2 corresponding to the cell 2 (i.e., the first cell) is greater than the set threshold, the local data center sends the first indication information of the silent cell 2 (i.e., the first cell) to the micro base station (i.e., the first micro base station) corresponding to the cell 2, so that the cell 2 does not send a message to the first user terminal in the cell 2, and therefore, it can be avoided that the cell 2 generates bursty interference fluctuation to an adjacent cell in a short-distance ultra-dense network.

After introducing the method for resisting the sudden interference fluctuation of the adjacent cell from the micro base station side, introducing the method from the local control center side, specifically as follows:

based on the same inventive concept, an embodiment of the present invention provides a method for resisting sudden interference fluctuation of an adjacent cell, which is applied to a local control center in a shorter-distance ultra-dense network, where a local data center is connected between the local control center and a micro base station, and please refer to fig. 4, where the method includes:

step 401: receiving signal quality measurement information forwarded by a local data center by a second micro base station corresponding to an adjacent cell of a first cell; the signal quality measurement information is obtained by performing signal quality measurement on a first cell by a second user terminal in an adjacent cell after the second user terminal sends a random symbol to the first micro base station, the random symbol is sent to a first user terminal in the first cell by the first micro base station when no data is sent, and the first cell is a cell which has interference on the adjacent cell and has a first idle time of a link layer data cache queue smaller than a set threshold value.

Step 402: and performing multi-cell joint resource allocation on the cells in the service area according to the signal quality measurement information.

Step 403: and forwarding the second indication information of the resource allocation to all the micro base stations in the service area through the local data center.

For example, in fig. 2, a cell 2 (i.e., a first cell) interferes with an adjacent cell, and a first idle duration of a link layer data buffer queue is less than a set threshold, when a local data center sends an indication to a first micro base station where the cell 2 is located and no data is sent, a random symbol is sent to a first user terminal in the cell 2, so that the cell 2 continues to interfere with the adjacent cell, and further a measured value of signal quality measured by a second user terminal in the adjacent cell remains unchanged, and after a second user terminal under the jurisdiction of the micro base station in the adjacent cell measures signal quality, the measured signal quality information is forwarded to a local control through the second micro base station and the local data center.

After receiving the signal quality information, the local control center performs multi-cell joint resource allocation on the cells in the service area according to the signal quality measurement information, for example, joint scheduling and resource allocation of joint time domain, frequency domain, space domain beam and power domain are performed on the cells 1 to 3 in the service area, so that the resources of each cell are orthogonal to each other as much as possible to avoid interference, and for the cells without orthogonal resource allocation, joint precoding and interference alignment are adopted to suppress inter-cell interference. And forwarding the second indication information of the resource allocation to all the micro base stations in the service area through the local data center.

In order to make those skilled in the art fully understand the technical solution provided by the present invention, how the above components in the shorter-distance ultra-dense network perform joint operation will be described, specifically please refer to the two embodiments provided below.

Fig. 5 is a flowchart of resisting sudden interference fluctuation of a neighboring cell when a link layer buffer queue of a first cell is idle for a short period according to a first embodiment of the present invention.

Step 501: and the local data center measures a first idle time of a link layer data cache queue corresponding to the first cell.

It should be noted that, in this embodiment, only the first cell is taken as an example, and the local data center actually measures the idle time of the link layer data buffer queue of each cell. For convenience of description, the idle duration corresponding to the first cell is referred to as a first idle duration.

Step 502: the local data center determines that the first idle time is less than a set threshold.

This indicates that the link layer data buffer queue corresponding to the first cell is in a short-term idle state.

Step 503: the local data center sends first indication information to the first micro base station.

Assuming that the first cell is located under the first micro base station, the first indication information is used to indicate that the first micro base station sends a random symbol to the first user terminal in the first cell when the first micro base station does not send data, that is, the first micro base station performs a setting operation on the first cell, and the setting operation is to send the random symbol to the first user terminal in the first cell when the first micro base station does not send data.

Step 504: and when the first micro base station does not send data, the first micro base station sends a random symbol to the first user terminal of the first cell.

Therefore, the interference of the first cell to the adjacent cell can be kept, the measured value of the signal quality measured by the second user terminal of the adjacent cell is unchanged, and the sudden interference fluctuation of the adjacent cell caused by the signal fluctuation of the first cell in a shorter-distance ultra-dense network can be reduced.

It should be noted that, in fig. 5, the first cell and the neighboring cell are located under the same micro base station, that is, the first micro base station is the same as the second micro base station.

Step 505: the first user terminal performs signal quality measurement on the first cell.

For example, CQI values and neighbor interference signal quality are measured.

It should be noted that, in a shorter-distance ultra-dense network, there are multiple micro base stations, each of which manages multiple user terminals, and a same user terminal may be located in both a first cell and a second cell, for example, a user terminal in an intersection region of cell 1 and cell 3 in fig. 2.

Step 506: the first user terminal sends signal quality measurement information to the first micro base station.

And the first user terminal feeds back the signal quality measurement information to the first micro base station through the uplink signal.

It should be noted that, in the shorter-distance ultra-dense network, there are multiple micro base stations, each of which governs multiple user terminals, and in practical application, the second user terminals governed by the second micro base stations corresponding to all the neighboring cells need to send signal quality measurement information to the corresponding second micro base stations. The second micro base station may be the same as or different from the first micro base station.

Step 507: and the first micro base station forwards the signal quality measurement information to a local control center through a local data center.

Meanwhile, step 507 a: and the first micro base station performs resource allocation based on the signal quality measurement information and sends the resource allocation to the first user terminal.

It should be noted that, when the second micro base station is different from the first micro base station and/or the second user terminal is different from the first user terminal, the actions that the second micro base station and the second user terminal need to perform are the same as the actions that the first micro base station and the first user terminal perform in steps 505 to 507a, respectively.

Step 508: and the local control center performs multi-cell joint resource allocation.

And after receiving all the signal quality measurement information, the local control center performs multi-cell joint resource allocation, and puts an allocation result into second indication information for sending.

Specifically, the local control center performs joint scheduling and resource allocation of joint time domain, frequency domain, space domain beam and power domain on cells in the service area, so that the resources of each cell are orthogonal to each other as much as possible to avoid interference, and joint precoding and interference alignment are adopted to suppress inter-cell interference for non-orthogonal resource allocation.

509: and the local control center sends the second indication information to all the micro base stations through the local control center.

510: and each micro base station carries out resource scheduling according to the second indication information.

It should be noted that, for convenience of description, only the first micro base station is shown in fig. 5.

Fig. 6 is a flowchart of resisting sudden interference fluctuation of a neighboring cell when a link layer buffer queue of a first cell provided in an embodiment of the present invention is idle for a long time.

Step 601: and the local data center measures a first idle time of a link layer data cache queue corresponding to the first cell.

It should be noted that, in this embodiment, only the first cell is taken as an example, and the local data center actually measures the idle time of the link layer data buffer queue of each cell.

Step 602: the local data center determines that the first idle time is greater than or equal to a set threshold.

This indicates that the link layer data buffer queue corresponding to the first cell has a long-term idle state.

Step 603: and the local data center sends first indication information to a first micro base station corresponding to the first cell.

The first cell is located under the first micro base station, and the first indication information is used for indicating the first micro base station to silence the first cell (namely, the first micro base station executes setting operation on the first cell), so that the first cell does not generate signal fluctuation, and interference signal fluctuation of adjacent cells is not caused, thereby reducing sudden interference fluctuation to the adjacent cells in a shorter-distance ultra-dense network.

Step 604: and the local data center reports the first micro base station to the local control center.

For example, the ID of the first micro base station corresponding to the first cell may be reported to the local control center, so that the local control center archives the ID.
