Description

Scheduling method, device and base station

technical field

The present invention relates to the field of communication technologies, in particular to a scheduling method, device and base station.

Background technique

LTE (Long Term Evaluation, long-term evolution) system currently has a variety of technologies to improve uplink performance: such as uplink frequency selection, uplink ICIC (Inter cell Interference collaboration, inter-cell interference coordination technology), etc., including some link layer Adaptive technology: MRC/IRC (Maximum RatioCombining/Interference Rejection Combining, Maximum Ratio Combining/Interference Rejection Combining) adaptive and advanced receivers, etc. However, this type of technology is independently processed by a single cell, and the demand for coordinated processing of a larger and wider multi-cell is not fully considered. Taking the current China Mobile 8R scenario as an example, through the analysis of the distribution of IOT (Interference Over Thermal noise) in the entire network, 67% of the interference comes from neighboring cells, that is, the IOT of neighboring cells in the station accounts for the main factor.

In an omni-directional base station, edge users located at the edge of a cell usually have strong interference to adjacent cells, while central users located at the center of the cell have weak interference to adjacent cells. The traditional way to suppress uplink interference between adjacent cells is as follows: determine the edge users and central users in the cell through the difference in path loss, that is, determine the user with large path loss as the edge user with strong external interference, and the user with small path loss The user is determined as the central user with weak external interference, as shown in Figure 1, there are three cells cell0, cell1 and cell2 in the figure, and the vertical table in the figure is the frequency domain, as can be seen from the figure, each of cell0, cell1 and cell2 The frequency band positions of the cell are divided into two parts, of which: 1/3 is used for the edge frequency band (the area filled with oblique lines in the figure), which is used to schedule edge users located at the edge of the cell, and 2/3 is used for the center frequency band (the white area in the figure ), which is used to schedule the center user located in the center of the cell, and when scheduling, the edge frequency band in the adjacent cell overlaps with the center frequency band, and the center frequency band overlaps with the edge frequency band in the adjacent cell. The interference is strong, so that the edge frequency bands of different cells can be staggered all or partially in the same time period, and the edge users in different cells that interfere strongly with adjacent cells are scheduled in different time periods, so that the edge users at the edge of the cell are affected. Interference is reduced and throughput of edge users is improved.

The traditional method of suppressing uplink interference between adjacent cells is suitable for omni-directional base stations, but not for directional base stations. This is because in the directional base station, the edge users with large path loss are weak interference to the outside world, such as main lobe edge users, and the central users with small path loss may be strong interference to the outside world, such as left and right side lobe edge users, so in the directional The base station still adopts the traditional method of suppressing uplink interference between adjacent cells, which will cause the edge users with weak external interference to overlap the scheduling frequency bands of central users with strong external interference in the adjacent cell, and then cause the edge users with weak external interference to be affected. The interference of the directional base station increases, which leads to the decrease of the throughput of the edge users with weak external interference in the directional base station.

Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings For further detailed explanation.

Fig. 2a is a schematic flowchart of a scheduling method provided by an embodiment of the present invention. As shown in Fig. 2a, the method may include: S101: The base station obtains the location area of the first terminal.

The scheduling method provided by the embodiment of the present invention can be applied to a directional base station, which includes at least two cells, a first cell and a second cell, and the base station can control the scheduling of terminals in the first cell and the second cell. In the embodiment of the present invention, the first cell is a serving cell of the first terminal, and the second cell is a neighboring cell of the first cell.

S102: The base station determines the interference type corresponding to the location area as the interference type of the first terminal.

The interference type of the first terminal indicates the degree of interference caused by the first terminal to the neighboring cell of the serving cell, that is, the second cell. In this embodiment of the present invention, optionally, the interference type may include strong interference and weak interference.

In the omni-directional base station, the interference caused by the terminal located at the edge of the serving cell to the adjacent cell of the serving cell is strong interference, and the interference caused by the terminal located in the center of the serving cell to the adjacent cell of the serving cell is weak interference, that is, the interference caused by the terminal located at the edge of the serving cell is weak. The interference type of the terminal is strong interference, and the interference type of the terminal located in the center of the serving cell is weak interference, so the difference in path loss of the terminal transmission signal can be directly used to determine the interference type of the terminal.

However, in a directional base station, due to the use of a directional antenna, the interference type of the terminal cannot be directly determined by the difference in path loss due to the influence of the beam transmitted by the directional antenna. For example, if the terminal located under the signal tower of the directional base station is calculated according to the traditional path loss difference, the interference type is weak interference; compared with other terminals in the same cell, these terminals receive the downlink RSRP (Reference Signal Receiving Power) of the serving cell. , Reference Signal Received Power) intensity is high, the strength of the downlink RSRP received from the adjacent cell of the serving cell is also large, and the interference caused to the adjacent cell is strong interference, that is, the interference type of the terminal actually located under the signal tower of the directional base station is strong interference.

However, according to the transmission beam characteristics of the directional antenna in the directional base station, the interference of the terminals in different location areas in the directional base station cell to the adjacent cell is determined, and the corresponding relationship between the location area and the interference type can be saved in advance in the base station, as shown in the figure 1 is a table of correspondence between location areas and interference types provided by the embodiment of the present invention.

Table 1

location area interference type main lobe area weak interference main lobe edge area weak interference Tower area strong interference left side lobe edge area strong interference right side lobe border area strong interference

Optionally, in this embodiment of the present invention, the base station may look up the interference type corresponding to the determined location area of the first terminal in a table of correspondence between location areas and interference types, and use the found interference type as the first terminal type of interference.

In the embodiment of the present invention, the edge users in the directional base station refer to the users located at the edge of the cell in the directional base station, that is, the users in the edge area of the main lobe in Table 1.

S103: The base station schedules the first terminal on the first frequency band of the first cell according to the interference type of the first terminal.

In the embodiment of the present invention, the first frequency band is different from the second frequency band, and the second frequency band refers to the frequency band where the base station schedules the second terminal in the second cell, the serving cell of the second terminal is the second cell, and the second terminal The interference type of is different from the interference type of the first terminal.

Optionally, the difference between the first frequency band and the second frequency band means that the first frequency band and the second frequency band do not overlap, as shown in Figure 2b, in which cell01 is the first cell, cell02 is the second cell, and the first frequency band is the first The area filled with oblique lines in the cell, and the second frequency band is the area filled with oblique lines in the second cell. It can be seen from the figure that the first frequency band does not overlap with the second frequency band. Optionally, the difference between the first frequency band and the second frequency band may also mean that the first frequency band partially overlaps with the second frequency band. Here, the partial overlap means that the overlap between the first frequency band and the second frequency band is smaller than that of the first frequency band and the second frequency band. Any one of , as shown in Figure 2c.

In the method provided by the embodiment of the present invention, by obtaining the location area where the first terminal is located in the serving cell, the degree of interference of the first terminal to the neighboring cells of the serving cell can be determined. When scheduling the first terminal, the base station controls the scheduling of the first The first frequency band of the first terminal in the cell is different from the second frequency band for scheduling the second terminal in the second cell, and the interference types of the first terminal and the second terminal are different, so that the first frequency occupied by the first terminal during scheduling The frequency band does not overlap with the second frequency band occupied by the second terminal during scheduling, or partially overlaps. When the first frequency band and the second frequency band do not overlap, the first terminal will not be interfered by the second terminal in the second cell, However, when the first frequency band partially overlaps with the second frequency band, the first terminal will be interfered by the second terminal only on a part of the first frequency band.

Compared with the prior art, the method provided by the embodiment of the present invention can stagger the frequency bands occupied by terminals with different interference types in different cells in the directional base station during scheduling, and reduce the marginal users located in the directional base station with weak external interference Interference from neighboring cells improves the throughput of edge users with weak external interference in the directional base station.

In the above table, the relationship of each location area in the first cell can be referred to as shown in Figure 3b. In the figure, A is the signal tower of the directional base station, and the cell of the directional base station is divided into multiple parts and numbered. The corresponding relationship between location areas is shown in Table 3:

table 3

location area serial number Tower area 001 main lobe area 002, 005 and 007 main lobe edge area 003 left side lobe edge area 004 right side lobe border area 006

S204: The base station determines the interference type corresponding to the location area as the interference type of the first terminal.

S205: The base station schedules the first terminal on the first frequency band of the first cell according to the interference type of the first terminal.

Wherein, step 204 is the same as step S102 in the embodiment shown in FIG. 2a, and step S205 is the same as step S103 in the embodiment shown in FIG.

The method provided by the embodiment of the present invention can determine the location area where the first terminal is located in the first cell by detecting the first uplink RSRP and the second uplink RSRP, and then determine the impact of the first terminal on the second cell according to the type of interference in the location area. The interference degree of the cell, and schedule the first terminal on the first frequency band of all frequency bands in the first cell. The first frequency band is different from the second frequency band in which the base station schedules the second terminal in the second cell. The second terminal and the first Terminals have different types of interference.

Fig. 4 is a schematic flowchart of a scheduling method provided by another embodiment of the present invention. As shown in Fig. 4, the method may include:

S301: The base station receives a report from the first terminal.

The report sent by the first terminal carries the first downlink RSRP of the first cell and the second difference between the first downlink RSRP and the second downlink RSRP in the second cell.

At present, when the existing terminal is working normally, it will always measure the downlink RSRP of the serving cell and the neighboring cells of the serving cell, and judge whether the RSRP difference between the serving cell and the neighboring cells of the serving cell satisfies the configured A3 offset (A3 The offset is defined as the difference between the downlink RSRP of the neighboring cell of the serving cell - the downlink RSRP of the serving cell) to determine whether to report the A3 time. Optionally, in the embodiment of the present invention, by adjusting the value of the existing A3 offset condition, the terminal can be controlled to automatically report the difference between the downlink RSRP of the neighboring cell of the serving cell and the downlink RSRP of the serving cell .

S302: The base station searches the location area of the first terminal in the first cell in the second preset relationship table according to the second difference.

In the embodiment of the present invention, the second preset relationship table includes: the corresponding relationship between the second difference and different location areas in the first cell, and/or, the combination of the second difference and the first downlink RSRP and the first Correspondence between different location areas in the cell, wherein the absolute value of the second difference is smaller than the third threshold or larger than the fourth threshold, corresponding to: the location area of the first cell is the left side lobe edge area or the right side lobe edge area in the first cell side lobe edge area; the absolute value of the second difference is between the third threshold and the fourth threshold, and the first downlink RSRP is in the third interval, corresponding to: the location area of the first cell is within the first cell The area under the tower; the absolute value of the second difference is between the third threshold and the fourth threshold, and the first downlink RSRP is in the fourth interval, corresponding to: the location area of the first cell is the main lobe in the first cell area or main lobe margin area.

The above-mentioned third threshold is smaller than the fourth threshold, and the lower limit of the third interval is less than or equal to the upper limit of the fourth interval. Based on the following formula (1), the calculation formula (2) for calculating the downlink RSRP can be obtained.

Cell downlink transmit power - downlink RSRP = terminal uplink transmit power - uplink RSRP (1)

Downlink RSRP = (cell downlink transmit power - terminal uplink transmit power) + uplink RSRP (2)

Further, the first power difference between the downlink transmission power of the first cell and the uplink transmission power of the first terminal, and the second power difference between the downlink transmission power of the second cell and the uplink transmission power of the first terminal are acquired in advance, and the above-mentioned On the basis of step S201 and Table 2, the second preset relationship is obtained.

S303: The base station determines the interference type corresponding to the location area as the interference type of the first terminal.

Wherein, step 303 is the same as step S102 in the embodiment shown in FIG. 2a, and step S304 is the same as step S103 in the embodiment shown in FIG.

Fig. 5 is a schematic flowchart of a scheduling method provided by another embodiment of the present invention. As shown in Figure 5, the method may include:

S401: The base station acquires the location area of the first terminal.

S402: The base station determines the interference type corresponding to the location area as the interference type of the first terminal.

S403: The base station selects a first frequency band allocated to the first terminal from all frequency bands of the first cell according to the interference type of the first terminal.

Optionally, in this embodiment of the present invention, as shown in FIG. 6, step S403 may include:

S4031: Determine whether the interference type of the first terminal is strong interference or weak interference. When the interference type of the first terminal is strong interference, perform S4032; when the interference type of the first terminal is weak interference, perform S4033.

S4032: The base station selects a first frequency band in a first area of all frequency bands of the first cell, and the first area is dedicated to scheduling terminals whose interference type is strong interference.

S4033: The base station selects a first frequency band in a second area of all frequency bands of the first cell, and the second area is dedicated to scheduling terminals whose interference type is weak interference.

The position of the first area may be arbitrarily selected from all frequency bands of the first cell as long as the first frequency band is different from the second frequency band. In the embodiment of the present invention, the first area is selected to be located at the high-frequency end or the low-frequency end of all frequency bands of the first cell.

In the embodiment of the present invention, when the first area is selected to be located at the high-frequency end or the low-frequency end of the entire frequency band of the first cell, the second area is located at the end of the entire frequency band of the second cell that is different from the first area.

Fig. 7 is a schematic flowchart of a scheduling method provided by another embodiment of the present invention. As shown in Figure 7, the method may also include:

S501: The base station acquires frequency band utilization rates of the first cell and the second cell.

After the base station schedules the first terminal on the first frequency band, the base station can also count the numbers of occupied radio bearers in all frequency bands of the first cell and the second cell respectively, and the number of occupied radio bearers in all frequency bands of the first cell is related to The ratio of the total number of radio bearers in all frequency bands is the frequency band utilization of the first cell, and the ratio of the number of occupied radio bearers in all frequency bands of the second cell to the total number of radio bearers in all frequency bands is the ratio of the second cell's Frequency Band Utilization.

S502: The base station judges whether the frequency band utilization rates of the first cell and the second cell are both smaller than a preset value. When both are less than the preset value, go to S503, otherwise, end. If the frequency band utilization rate is less than a preset value, it means that there is an idle frequency band in the cell. Optionally, in this embodiment of the present invention, the preset value may be 30%.

S503: The base station judges whether the first frequency band partially overlaps with the second frequency band. When the first frequency band partially overlaps the second frequency band, perform S504, otherwise, end.

In other embodiments of the present invention, optionally, S503 may be performed first, and then step S501 may be performed, or step S501 and step S503 may be performed simultaneously. As long as it is satisfied that the frequency band utilization rates of the first cell and the second cell are both less than a preset value and the first frequency band partially overlaps with the second frequency band, 504 may be performed.

S504: The base station determines a third frequency band in all frequency bands of the first cell.

Partial overlap between the first frequency band and the second frequency band will cause the terminal whose interference type is weak interference among the first terminal and the second terminal to be partially interfered by the terminal whose interference type is strong interference, and the overlap between the first frequency band and the second frequency band The larger the part, the greater the degree of interference received by the terminal whose interference type is weak interference among the first terminal and the second terminal.

Therefore, the purpose of determining the third frequency band is to find a frequency band in the first cell whose overlapping portion with the second frequency band is smaller than the overlapping portion between the first frequency band and the second frequency band in the case that there are idle frequency bands in the first cell and the second cell Scheduling the first terminal, so as to reduce the interference from the second cell when the interference type of the first terminal is weak interference, or reduce the interference caused to the second cell when the interference type of the first terminal is strong interference interference. In the embodiment of the present invention, the third frequency band does not overlap with the second frequency band, or, the overlapping portion between the third frequency band and the second frequency band is smaller than the overlapping portion between the first frequency band and the second frequency band.

The solution provided by the embodiment of the present invention will be described below by taking FIG. 8a and FIG. 8b as examples.

In Figure 8a, the left part is a schematic diagram of the frequency band before the third frequency band is determined, in the figure cell01 is the first cell, cell02 is the second cell, the first frequency band partially overlaps with the second frequency band, and the right part is a schematic diagram of the frequency band after the third frequency band is determined , it can be seen from the figure that the third frequency band has no overlap with the second frequency band. In Fig. 8b, the left part is a schematic diagram of the positions of the first frequency band and the second frequency band, in which the first frequency band partially overlaps with the second frequency band, and the right part is the third frequency band determined by the base station in the first cell, from the figure It is seen that the overlapping portion of the third frequency band and the second frequency band is smaller than the overlapping portion of the first frequency band and the second frequency band.

Optionally, in this embodiment of the present invention, the specific method of determining the third frequency band may be: taking the central position of all frequency bands of the first cell as a symmetry point, and determining a frequency band that is completely symmetrical with the first frequency band as the third frequency band, or , taking the central position of the first area or the second area where the first frequency band is located as a symmetry point, and determining a frequency band that is completely symmetrical to the first frequency band as the third frequency band. Of course, in other embodiments of the present invention, it is only necessary to satisfy the requirement that the third frequency band does not overlap with the second frequency band, or that the overlapping portion between the third frequency band and the second frequency band is smaller than the overlapping portion between the first frequency band and the second frequency band, and The third frequency band may be determined in other ways.

S505: The base station schedules the first terminal on the third frequency band.

Optionally, in the embodiment of the present invention, as shown in FIG. 7, the method may further include:

S506: The base station finishes scheduling the first terminal on the first frequency band.

This step may be performed after step S505, or may be performed after it is determined that both the frequency band utilization rates of the first cell and the second cell are less than a preset value and the first frequency band partially overlaps with the second frequency band.

In the method provided by the embodiment of the present invention, when the first frequency band partially overlaps with the second frequency band, the position of the frequency band for scheduling the first terminal can also be adjusted by detecting the actual frequency band utilization rate of the cell in the base station, so that when the second When the interference type of a terminal is weak interference, reduce the interference received by the terminal whose interference type is strong interference in the second cell, or, when the interference type of the first terminal is strong interference, reduce the interference to the second cell whose interference type is strong interference Interference caused by weakly interfering terminals. Therefore, this method can reduce the interference of neighboring cells for edge users located in the directional base station with weak external interference, and improve the throughput of the edge users with weak external interference in the directional base station.

Optionally, in the embodiment of the present invention, in step S503, when it is judged that the first frequency band partially overlaps with the second frequency band, the method may further include:

The base station determines a fourth frequency band in the second cell, and the base station schedules the second terminal on the fourth frequency band.

In the embodiment shown in FIG. 7 , in the case that there are free frequency bands in the first cell and the second cell, search for a frequency band in the first cell whose overlapping portion with the second frequency band is smaller than the overlapping portion between the first frequency band and the second frequency band to schedule the first terminal. Optionally, in this embodiment of the present invention, it is also possible to search for a fourth frequency band in the second cell, and the fourth frequency band does not overlap with the first frequency band, or, the overlap between the fourth frequency band and the first frequency band is smaller than that between the first frequency band and the first frequency band. The overlapping portion of the second frequency band. Similarly, when the interference type of the first terminal is weak interference, the interference from the second cell can be reduced, or when the interference type of the first terminal is strong interference, the interference caused to the second cell can be reduced.

Optionally, when the base station schedules the second terminal on the fourth frequency band, the method may further include: the base station finishes scheduling the second terminal on the second frequency band.

Same as step S506, ending the scheduling of the second terminal on the second frequency band can be performed after the base station starts to schedule the second terminal on the fourth frequency band, or it can be performed after determining the frequency band utilization of the first cell and the second cell It is executed after the rates are all less than the preset value and the first frequency band partially overlaps with the second frequency band.

In the method provided by the present invention, when the first frequency band partially overlaps with the second frequency band, the position of the frequency band for scheduling the second terminal can also be adjusted by detecting the actual frequency band utilization rate of the cell in the base station. Therefore, this method can also reduce the interference of neighboring cells for marginal users located in the directional base station with weak external interference, and improve the throughput of the marginal users with weak external interference in the directional base station.
