Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the rapid development of services, a single frequency network has been unable to meet the capacity requirements of users. In service hot spots and explosion areas, the 4G network is often extended to multi-frequency networks, such as three-frequency networks and four-frequency networks. However, in many hot spot scenarios, some frequency bands of the 4G network are prone to external interference. In some areas affected by interference, even the affected frequency band may not be used. Therefore, how to reduce the influence of external interference and reuse the interfered spectrum resources becomes the focus of the current 4G network operation.
For this situation, in the prior art, a method of avoiding an interference frequency band is generally adopted, and an interfered frequency band is abandoned and changed into a clean frequency band. However, in actual use, the amount of spectrum resources is limited, and as traffic volume rapidly increases, operators have put all spectrum resources into full use. Therefore, if the interfered spectrum resources are directly abandoned, the spectrum resources are more strained. Especially for hot spot areas, the abandonment of the interfered frequency band easily leads to the further reduction of the number of frequency band resources, thereby causing the capacity problem to become more serious.
In order to solve the problems, the application provides an anti-interference communication method. In practical use, the transmission power of the base station is far greater than that of the mobile phone. And the interference source is mostly a low power signal. Therefore, during communication, the interference experienced is usually uplink interference. In addition, the currently common 4G standard is LTE-FDD. In the LTE-FDD network, the capacity bottleneck mainly lies in data downlink in the data uplink and downlink process.
Aiming at the uplink interference and downlink capacity bottleneck of data, the method for reducing the uplink interference influence of the data of the 4G network, improving the downlink data capacity and improving the user perception through uplink and downlink decoupling and carrier aggregation technology is provided. Specifically, the uplink and downlink decoupling technology is utilized to decouple the interfered frequency band, namely the uplink frequency band and the downlink frequency band of the first carrier. According to the method and the device, a carrier aggregation technology is utilized to aggregate the downlink frequency band of the first carrier and the uplink frequency band of the second carrier so as to ensure the capacity of downlink data. Meanwhile, the uplink frequency band of the first carrier in the first cell is replaced by the uplink frequency band of the second carrier, so that normal uplink of data in the first cell is guaranteed.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 illustrates a scene diagram of interference-resistant communication according to an embodiment of the present application. As shown in fig. 1, the figure includes a terminal and a base station. The data interaction process between the terminal and the base station comprises data uplink and data downlink.
As shown in fig. 1(a), the first carrier used by the first cell in which the terminal is located includes carrier a and carrier B. Due to external interference, the uplink frequency bands of carrier a and carrier B are interfered. The terminal cannot realize data uplink through the carrier A and the carrier B. But the base station can still realize the downlink of data through the downlink frequency bands of the carrier a and the carrier B.
As shown in fig. 1(b), the base station optimizes the carrier of the first cell using the method shown in the present application. After optimization, the terminal of the first cell realizes uplink of data through uplink frequency bands of the carrier C and the carrier D. Meanwhile, the downlink carrier of the base station to the first cell is aggregated with carrier a, carrier B, carrier C and carrier D. The method not only ensures the uplink data of the interfered cell, but also recycles the interfered frequency band, improves the downlink data capacity, saves the investment cost and improves the user perception of the interference area.
In the present application, a base station is used as an execution subject, and the following anti-interference communication method is executed. Specifically, the execution subject may be a hardware device of the base station, or a software application implementing the following embodiments in the base station, or a computer readable storage medium installed with the software application implementing the following embodiments, or computer instructions implementing the following embodiments.
Fig. 2 shows a flowchart of a method for interference-free communication according to an embodiment of the present application. On the basis of the embodiment shown in fig. 1, as shown in fig. 2, with a base station as an execution subject, the method of this embodiment may include the following steps:
s101, judging whether the first carrier is interfered or not according to the background noise of the first carrier.
In this embodiment, the base station obtains the background noise of each measurement point in the first cell. The first cell is a cell for realizing data interaction with the base station by using the first carrier. And the base station determines whether the first carrier is interfered or not according to the background noise. The frequency of the base station acquiring the background noise of each measurement point can be determined according to actual needs. For example, the base station acquires the noise floor from each measurement point every hour.
Or, the base station may also directly obtain alarm information of each measurement point in the first cell. The base station may determine that the first carrier of the first cell is interfered according to the alarm information. And each measuring point in the first cell can measure the background noise of the first carrier wave in real time. And when the background noise of the first carrier wave is abnormal, the measuring point generates alarm information according to the abnormality and sends the alarm information to the base station.
S102, if the first carrier is interfered, the uplink frequency band of the first carrier is forbidden, and the uplink frequency band of the second carrier is used for realizing data uplink.
In this embodiment, when the base station determines that the first carrier is interfered, the terminal of the user in the first cell usually cannot implement data uplink, or the efficiency and accuracy of data uplink are very low. At this time, the base station disables the uplink frequency band of the first carrier in the first cell. The forbidding of the uplink frequency band of the first carrier can effectively avoid that the uplink data of the terminal in the first cell is abnormal when the terminal is in uplink data, thereby reducing the user experience. Meanwhile, the base station selects a second carrier of the second cell, and takes the uplink frequency band of the second carrier as the uplink frequency band of the first cell. When the terminal of the first cell needs uplink data, the terminal triggers switching to switch the original first carrier into the second carrier, so that normal uplink of the data is realized.
In one example, the cell in which the first carrier is located is a first cell and the cell in which the second carrier is located is a second cell.
In this example, the first cell uses the first carrier to implement uplink and downlink of data without being interfered. And the second cell realizes uplink and downlink of data by using the second carrier. The first cell and the second cell realize the access of the 4G network through the same base station.
And S103, realizing data downlink by using the downlink frequency band after the aggregation of the first carrier and the second carrier.
In this embodiment, the base station acquires the downlink frequency band in the first carrier after completing the switching of the uplink frequency band in the first cell. And the base station polymerizes the downlink frequency band in the first carrier and the downlink frequency band in the second carrier to obtain a polymerized downlink frequency band. And the base station determines the downlink frequency band after the aggregation as the downlink frequency band corresponding to the uplink frequency band of the second carrier, and applies the downlink frequency band to the first cell and the second cell.
For example, as shown in fig. 3, the communication carriers of the base station include carrier a, carrier B, carrier C, and carrier D. Where carrier a and carrier B apply to a first cell and carrier C and carrier D apply to a second cell. For convenience of illustration, the uplink frequency band and the downlink frequency band of the first cell and the second cell are assumed to have capacities of 30 MHz. As shown in fig. 3(a), in the initial state, the first cell communicates using carrier a and carrier B. The second cell communicates using carrier C and carrier D. When the carrier a and the carrier B of the first cell are interfered, as shown in fig. 3(B), the base station may optimize the communication situation of the first cell using the above S101 to S103. The first cell uses the carrier C and the carrier D to realize data uplink, and uses the aggregated carrier of the carrier A, the carrier B, the carrier C and the carrier D to realize data downlink. The capacity of the aggregated carrier of the carrier A, the carrier B, the carrier C and the carrier D is 60 MHz.
After the base station completes the aggregation of the first carrier and the second carrier, for the downlink frequency band after the aggregation, the first cell and the second cell share the use of the main frequency band and the auxiliary frequency band according to the actual situation when the data is downlink. The sharing scheme specifically includes:
in one example, when the reference signal received power is less than or equal to a second preset value, the terminal of the first cell triggers inter-frequency point handover to access the second carrier.
In this example, the base station stores a second preset value. The second preset value may be an empirical value. The value of this second preset value may be-85 dBm.
And when the reference signal receiving power is less than or equal to a second preset value, the base station determines that the first carrier of the first cell cannot bear downlink data. At this time, the terminal in the first cell triggers the inter-frequency point handover to access the second carrier. And the base station sends the downlink data to the terminal of the first cell through the downlink frequency band of the second carrier.
Otherwise, when the reference signal received power is greater than the second preset value, the base station determines that the first carrier of the first cell can carry downlink data. At this time, the terminal in the first cell does not trigger the inter-frequency point handover, and still uses the first carrier. And the base station transmits the downlink data to the terminal of the first cell through the downlink frequency band of the first carrier.
In another example, when the reference signal received power is greater than a third preset value, the terminal of the second cell triggers handover to the first carrier.
In this example, the base station stores a third preset value. The third preset value may be an empirical value. The value of this third preset value may be-81 dBm.
And when the reference signal received power is greater than a third preset value, the base station determines that the first carrier data has vacant load. At this time, the terminal in the second cell may trigger the different frequency point switching to access the first carrier according to actual needs. And the base station sends the downlink data to the terminal of the second cell through the downlink frequency band of the first carrier.
According to the anti-interference communication method, the base station acquires the background noise of each measuring point in the first cell. And the base station determines whether the first carrier is interfered or not according to the background noise. When the base station determines that the first carrier is interfered, the base station forbids an uplink frequency band of the first carrier in the first cell. Meanwhile, the base station selects a second carrier of the second cell, and takes the uplink frequency band of the second carrier as the uplink frequency band of the first cell. After completing the switching of the uplink frequency band in the first cell, the base station acquires the downlink frequency band in the first carrier. And the base station polymerizes the downlink frequency band in the first carrier and the downlink frequency band in the second carrier to obtain a polymerized downlink frequency band. And the base station determines the downlink frequency band after the aggregation as the downlink frequency band corresponding to the uplink frequency band of the second carrier, and applies the downlink frequency band to the first cell and the second cell. In the method and the device, the uplink carrier of the first cell is switched to the second carrier, so that the problem that data cannot be uplink after the first carrier is interfered in the first cell is avoided. The uplink frequency band of the first carrier is forbidden, so that the problem that the terminal still preferentially uses the first carrier after the uplink data of the first cell is switched to the second carrier, and the data uplink cannot be realized is solved. The method and the device have the advantages that the downlink data of the first carrier and the downlink data of the second carrier are aggregated, so that the capacity of the downlink data of the first cell and the capacity of the downlink data of the second cell are expanded, the data downlink efficiency of the first cell and the data downlink efficiency of the second cell are improved, and the frequency band resources of the first carrier and the second carrier are fully utilized.
Fig. 4 is a flowchart illustrating another method for interference-free communication according to an embodiment of the present application. On the basis of the embodiments shown in fig. 1 to fig. 3, as shown in fig. 4, with a base station as an execution subject, the method of the embodiment may include the following steps:
s201, when the background noise of the first carrier is larger than a first preset value, determining that the first carrier is interfered.
In this embodiment, the base station stores a first preset value. The first preset value may be an empirical value. The value of the first preset value may be-100 dBm. And after obtaining the background noise, the base station compares the first preset value with the background noise. And when the background noise is larger than a first preset value, the base station determines that the first carrier is interfered. And when the background noise is less than or equal to a preset value, the base station considers that the first carrier is not interfered or the interference degree is not deep.
S202, decoupling an uplink frequency band and a downlink frequency band of the first carrier.
In this embodiment, after determining that the first carrier is interfered, the base station may perform a decoupling operation on the first carrier to obtain an uplink frequency band of the first carrier and a downlink frequency band of the first carrier, respectively.
And S203, if the first carrier is interfered, forbidding the uplink frequency band of the first carrier, and realizing data uplink by using the uplink frequency band of the second carrier.
And S204, using the downlink frequency band after the aggregation of the first carrier and the second carrier to realize data downlink.
Steps S203 and S204 are similar to steps S102 and S103 in the embodiment of fig. 2, and are not described again in this embodiment.
According to the anti-interference communication method, after the base station obtains the background noise, the first preset value is compared with the background noise. And when the background noise is larger than a first preset value, the base station determines that the first carrier is interfered. After determining that the first carrier is interfered, the base station may perform a decoupling operation on the first carrier to obtain an uplink frequency band of the first carrier and a downlink frequency band of the first carrier, respectively. The base station disables the uplink frequency band of the first carrier in the first cell. Meanwhile, the base station selects a second carrier of the second cell, and takes the uplink frequency band of the second carrier as the uplink frequency band of the first cell. After completing the switching of the uplink frequency band in the first cell, the base station acquires the downlink frequency band in the first carrier. And the base station polymerizes the downlink frequency band in the first carrier and the downlink frequency band in the second carrier to obtain a polymerized downlink frequency band. And the base station determines the downlink frequency band after the aggregation as the downlink frequency band corresponding to the uplink frequency band of the second carrier, and applies the downlink frequency band to the first cell and the second cell. In the method and the device, the uplink carrier of the first cell is switched to the second carrier, so that the problem that data cannot be uplink after the first carrier is interfered in the first cell is avoided. The uplink frequency band of the first carrier is forbidden, so that the problem that the terminal still preferentially uses the first carrier after the uplink data of the first cell is switched to the second carrier, and the data uplink cannot be realized is solved. The method and the device have the advantages that the downlink data of the first carrier and the downlink data of the second carrier are aggregated, so that the capacity of the downlink data of the first cell and the capacity of the downlink data of the second cell are expanded, the data downlink efficiency of the first cell and the data downlink efficiency of the second cell are improved, and the frequency band resources of the first carrier and the second carrier are fully utilized.
