Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1, a flowchart of specific steps of a method for processing atmospheric waveguide interference according to an embodiment of the present invention is shown and applied to a first base station.
Step 101, detecting whether the target cells in the carrier aggregation cell set have atmospheric waveguide interference, wherein the cells in the carrier aggregation cell set have the same long-distance same-frequency interference source; the target cell is a cell in which the atmosphere waveguide detection switch in the carrier aggregation cell set is in an on state.
Atmospheric waveguide interference is actually long-distance co-channel interference, i.e. under specific climatic, terrain and temperature environments, the propagation loss of electromagnetic wave energy in the atmospheric waveguide layer is very small, and interference is caused to a remote receiver. Atmospheric waveguide interference makes it possible for the radar to observe several times the target at normal detection distance, but for time-division long term evolution (TD-LTE, time Division Long Term Evolution) systems, it can cause stronger co-channel interference. From the principle and practical point of view, the atmospheric waveguide interference does not affect the second Generation mobile communication technology (2G,Second Generation), the third Generation mobile communication technology (3 g,3 rd-Generation) and the fourth Generation mobile communication technology (4G,the4thGeneration mobile communication technology) of the frequency division duplex (FDD, frequency Division Duplexing) system, and mainly affects the time division duplex (TDD, time Division Duplexing) system. The invention mainly provides a method for processing atmospheric waveguide interference of a TD-LTE system.
For the detection of the atmospheric waveguide, it is preferable to perform the atmospheric waveguide interference identification according to the frequency domain characteristic of the atmospheric waveguide interference, and if the background noise of all or most of the physical resource blocks (PRBs, physical Resource Blocks) covering the base stations of the cells in the carrier aggregation cell set is increased at the same time, and the interference intensity of the idle PRBs is not greatly different from the interference intensity of the non-idle PRBs, it is determined that the cells are interfered by the atmospheric waveguide. Other methods of detecting atmospheric waveguide interference may be employed by those skilled in the art, and the present application is not particularly limited.
The application processes the atmospheric waveguide interference by taking each cell in the carrier aggregation cell as a whole. Carrier aggregation (CA, carrier Aggregation) refers to that the frequency band used by the long term evolution Advanced (LTE-a, long Term Evolution-Advanced) system is formed by aggregation of 2 or more long term evolution (LTE, long Term Evolution) carrier elements (CC, component Carrier) to form a frequency bandwidth that meets the LTE-a related technical specifications, such as 10MHz, 20MHz, and even 100MHz. Carrier aggregation is a key feature of LTE-a, and by aggregating multiple continuous or discontinuous carrier units into a larger frequency band, a terminal can access multiple carriers simultaneously, and perform uplink and downlink data transmission on the multiple carrier units simultaneously. When carrier aggregation configuration is carried out, adding the cells where the aggregated carrier units are located into a carrier aggregation cell set, wherein the cells in the carrier aggregation cell set can be covered by the same base station or a plurality of near-end base stations. In the embodiment of the present application, the first base station is a base station covering any target cell in the carrier aggregation cell set.
Under the atmospheric waveguide phenomenon, electromagnetic waves are refracted by the atmosphere to realize long-distance transmission, and when the long-distance transmission time exceeds the uplink and downlink protection time slot (GP, guard Period) of the TDD system, the downlink signal of the far-end base station is received by the near-end base station in the uplink receiving time slot of the near-end base station, so that the uplink signal receiving of the near-end base station is interfered. Because the carrier aggregation cell sets are cell sets configured in the station or between the near-end stations, if one cell in the carrier aggregation cell set is interfered by the atmospheric waveguide, other cells are also interfered by the atmospheric waveguide, namely, each cell in the carrier aggregation cell set has the same long-distance same-frequency interference source.
The method initializes the target cell in the carrier aggregation cell set, adjusts the atmosphere waveguide detection switch of the target cell to be in an on state, and detects whether atmosphere waveguide interference exists in the target cell in the carrier aggregation cell set in which the atmosphere waveguide detection switch is in the on state.
From the time dimension, atmospheric waveguide interference generally occurs between nine pm and nine am, and is not present at any time, so there is no need to continuously monitor the cell for atmospheric waveguide interference twenty-four hours. In the embodiment of the invention, the atmospheric waveguide detection switch is arranged on the cell, so that the atmospheric waveguide detection switch of the cell can be started only in the period with higher occurrence probability of atmospheric waveguide interference, whether the cell has atmospheric waveguide interference or not is detected, the atmospheric waveguide detection switch of the cell is not started in the period with lower occurrence probability of atmospheric waveguide interference, and whether the cell has atmospheric waveguide interference or not is not detected, thereby carrying out the atmospheric waveguide interference detection in a targeted manner according to the time characteristic of the atmospheric waveguide interference, not only improving the anti-interference capability of the cell to the atmospheric waveguide, but also reducing the resource consumption of the anti-interference to the base station.
Step 102, if at least one target cell in the carrier aggregation cell set has atmospheric waveguide interference, each cell in the carrier aggregation cell set is adjusted to be in an anti-interference state.
In the embodiment of the invention, the cells in the carrier aggregation cell set are used as a whole to carry out the atmospheric waveguide interference treatment, and if at least one target cell in the carrier aggregation cell set has atmospheric waveguide interference, each cell in the carrier aggregation cell set is adjusted to be in an anti-interference state.
The cell performs the atmospheric waveguide interference processing under the anti-interference state so as to reduce the influence of the atmospheric waveguide interference on communication.
Preferably, an F+D/F+E dual-layer network is deployed; if the cell is detected to enter an anti-interference state, migrating a user of the cell from an F cell to a D or E cell; wherein D, E, F is the working frequency band of the TDD system, F frequency band is 1.9GHz, D frequency band is 2.6GHz, E frequency band is 2.3GHz, and the frequency band is an indoor coverage special frequency band.
Preferably, if it is detected that a cell enters an anti-interference state, adjusting an antenna pitch angle of the cell according to an antenna hanging height of the cell, wherein the larger the antenna hanging height is, the larger the antenna pitch angle is; the smaller the antenna hook height, the smaller the antenna pitch angle.
Specifically, if the antenna hanging height of the cell is more than 45 meters, adjusting the antenna pitch angle of the cell to be not less than 10 degrees; if the antenna hanging height of the cell is more than 40 meters and less than 45 meters, adjusting the antenna pitch angle of the cell to be not less than 8 degrees; if the antenna hanging height of the cell is more than 30 meters and less than 40 meters, adjusting the antenna pitch angle of the cell to 8 degrees; if the antenna hanging height of the cell is smaller than 30 meters, the antenna pitch angle of the cell is kept unchanged.
The invention provides a method for processing atmospheric waveguide interference, which comprises the following steps: detecting whether the target cells in the carrier aggregation cell set have atmospheric waveguide interference or not, wherein the cells in the carrier aggregation cell set have the same long-distance same-frequency interference source; the target cell is a cell in which an atmospheric waveguide detection switch in the carrier aggregation cell is in an on state; and if at least one target cell in the carrier aggregation cell set has atmospheric waveguide interference, adjusting each cell in the carrier aggregation cell set to be in an anti-interference state. The invention can maintain the consistency of the carrier aggregation cell set for the atmospheric waveguide interference processing, so that each cell in the carrier aggregation cell set can synchronously resume normal communication.
Example two
Referring to fig. 2, a flowchart of specific steps of a method for processing atmospheric waveguide interference according to a second embodiment of the present invention is shown and is applied to a first base station.
Step 201, if a target cell belonging to a second base station exists in a carrier aggregation cell set, acquiring an atmospheric waveguide interference detection result of the target cell of the second base station from the second base station; each cell in the carrier aggregation cell set has the same long-distance same-frequency interference source; the target cell is a cell in which the atmosphere waveguide detection switch in the carrier aggregation cell set is in an on state.
The cell in the carrier aggregation cell set may be a cell covered by the same base station or a cell covered by a different base station, and if the cell in the carrier aggregation cell set belongs to a second base station, that is, the cell in the carrier aggregation cell set is a cell covered by a non-same base station, the atmospheric waveguide interference detection result of the cell of the second base station is obtained from the second base station.
If the carrier aggregation cells are concentrated to the cells belonging to the second base station, the first base station acquires the atmospheric waveguide interference detection result of the cells of the second base station from the second base station through an inter-base station X2 interface.
For example, if the carrier aggregation CELL set includes CELLs CELL1, CELL2, CELL3, CELL4, CELL5, and CELL6, where the CELLs CELL1-CELL4 are covered by the BASE station BASE1 and the CELLs CELL5-CELL6 are covered by the BASE station BASE2, the BASE station BASE1 needs to obtain the atmospheric waveguide interference detection result of the CELLs CELL5-CELL6 from the BASE station BASE2 through the inter-BASE station X2 interface, and thus, the BASE station BASE1 obtains the atmospheric waveguide detection results of all the CELLs in the carrier aggregation CELL set.
Step 202, judging whether the target cell in the carrier aggregation cell has the atmospheric waveguide interference according to the atmospheric waveguide interference detection result of the target cell of the first base station and the atmospheric waveguide interference detection result of the target cell of the second base station.
And step 203, if at least one target cell in the carrier aggregation cell set has atmospheric waveguide interference, adjusting the cell belonging to the first base station in the carrier aggregation cell set to an anti-interference state.
This step may be described with reference to step 102, and will not be described in detail herein.
Preferably, in another embodiment of the present invention, if at least one target cell in the carrier aggregation cell set has the atmospheric waveguide interference, the protection time slot of each cell in the carrier aggregation cell set is increased.
The radio frame structure of the TD-LTE system is 10ms and consists of 10 subframes of 1ms, wherein the subframes comprise 8-9 common subframes and 1-2 special subframes. The normal subframe is used for data scheduling and transmission, and the special subframe comprises 3 special time slots: doWnlink Pilot Time Slot (DwPTS), uplink Pilot Time Slot (UpPTS, uplink Pilot Time Slot), guard Time Slot (GP, guard Period), dwPTS being used for data transmission of normal DoWnlink control channel and DoWnlink shared channel, upPTS being used for carrying uplink physical random access channel and Pilot signal, GP being used for Guard interval between uplink and DoWnlink, total length of special Time Slot being generally 14 orthogonal frequency division multiplexing (OFDM, orthogonal Frequency Division Multiplexing) symbols. The proportion of special subframes used by the F frequency band of the TD-LTE network at present is 9:3:2, wherein 9 is the number of symbols used by DwPTS, 3 is the number of symbols of GP, 2 is the number of symbols of UpPTS, one symbol number is 71.4us, the corresponding protection distance is 21.4km, and thus the protection distance corresponding to the GP of 3 symbols is 64.3km.
In the embodiment of the present invention, if at least one target cell in the carrier aggregation cell set has the atmospheric waveguide interference, the protection time slot of each cell in the carrier aggregation cell set is increased, for example, the proportion of the special subframe is adjusted to be 3:9:2, and the protection time slot is increased to be 9 symbol numbers, at this time, the corresponding protection distance is 192.6km, so as to reduce the influence of the far-end interference caused by the atmospheric waveguide.
Step 204, notifying the second base station to adjust the cells belonging to the second base station in the carrier aggregation cell set to an anti-interference state.
For the cells in the carrier aggregation cell set, which do not belong to the coverage of the first base station, the second base station corresponding to the cells is required to adjust the cells to an anti-interference state, so that when the first base station detects that at least one cell in the carrier aggregation cell set has the atmospheric waveguide interference, the second base station is informed to adjust the cells of the second base station to the anti-interference state.
And step 205, if none of the target cells in the carrier aggregation cell set has atmospheric waveguide interference, adjusting each cell in the carrier aggregation cell set to be in a normal communication state.
For the carrier aggregation cell set with the atmospheric waveguide detection just started, if the target cells in the carrier aggregation cell set have no atmospheric waveguide interference, each cell in the carrier aggregation cell set keeps a normal communication state, namely, the current communication parameter value is kept unchanged. Taking adjusting the special subframe ratio as an example, when the situation that the target cells in the carrier aggregation cell set are not interfered by the atmospheric wave guide is detected, keeping the special subframe ratio of each cell in the carrier aggregation cell set to be 9:3:2 unchanged.
For the carrier aggregation cell set entering the anti-interference state, each cell in the carrier aggregation cell set is adjusted to be in a normal communication state only when all target cells in the carrier aggregation cell set are detected to have no atmospheric waveguide interference, namely, the communication parameter value of the cell is adjusted to be the communication parameter value before entering the anti-interference state. Taking adjusting the special subframe ratio as an example, when the target cells in the carrier aggregation cell set are detected to have no atmospheric waveguide interference, adjusting the special subframe ratio of each cell in the carrier aggregation cell set from 3:9:2 in the anti-interference state to 9:3:2 in the normal communication state.
The invention provides a method for processing atmospheric waveguide interference, which comprises the following steps: if the carrier aggregation cells intensively exist the target cells belonging to the second base station, acquiring an atmospheric waveguide interference detection result of the target cells of the second base station from the second base station; judging whether the target cells in the carrier aggregation cell set have atmospheric waveguide interference according to the atmospheric waveguide interference detection result of the target cell of the first base station and the atmospheric waveguide interference detection result of the target cell of the second base station; if the target cells in the carrier aggregation cell set do not have atmospheric waveguide interference, adjusting each cell in the carrier aggregation cell set to be in a normal communication state; if at least one target cell in the carrier aggregation cell set has atmospheric waveguide interference, adjusting the cell belonging to the first base station in the carrier aggregation cell set to be in an anti-interference state; and notifying the second base station to adjust the cells belonging to the second base station in the carrier aggregation cell set to an anti-interference state. According to the invention, by arranging the atmospheric waveguide detection switch, the atmospheric waveguide interference of the cell can be monitored in a targeted manner according to the time characteristic of the atmospheric waveguide interference, continuous monitoring is not needed, and the equipment operation loss is reduced. The invention can maintain the consistency of the carrier aggregation cell set for the atmospheric waveguide interference processing, so that each cell in the carrier aggregation cell set can synchronously resume normal communication, and the processing efficiency of the atmospheric waveguide interference of each cell in the carrier aggregation cell set is improved.
