Method and device for interference coordination, and base station

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to an interference coordination method and device, and a base station.

Background technique

The 5G network needs to support a 1,000-fold increase in business volume. The core technology is to deploy an ultra-dense network. By increasing the number of low-power sites and reducing the radius of the cell, the transmission capacity per unit area can be improved and the system capacity can be improved. In an ultra-dense network scenario, the site deployment density increases and the distance between sites decreases, which will lead to more serious inter-cell interference. At the cell edge, it is difficult to effectively improve user speed and experience. And due to the increase of adjacent stations, there may be multiple interference sources with similar strengths, which makes the interference situation more complicated. How to avoid inter-cell interference through site cooperation is an important problem to be solved in ultra-dense networks.

The key to inter-cell interference coordination in the time domain in an ultra-dense networking scenario is to determine the almost blank subframe (ABS) patterns used by the base station to which the interfering cell belongs and the base station to which the interfered cell belongs. The traditional method is to use the interfered base station to which the interfered cell belongs to discover the interfering base station to which the interfering cell belongs to a certain user, and then send a time-domain inter-cell interference coordination request to the interfering base station according to the network quality feedback from the user, and then interfere. The base station sends an ABS pattern set to the interfered base station, and the interfered base station selects an ABS pattern and feeds it back to the interferer base station for confirmation, and then performs resource scheduling based on the confirmed pattern; or the interfered base station directly sends the ABS pattern set to the interferer base station, which is determined by After the interfering base station selects an ABS pattern, the interfering base station and the interfered base station perform resource scheduling based on the confirmed pattern. However, with the rapid development of mobile Internet services and the rise of 5G+ vertical industry services, business types with regular changes in network requirements have gradually emerged. For example, the robot 4K video inspection service starts continuous 4K video live broadcast after the user equipment starts to work. The demand for the mobile network is relatively fixed, that is, the 4K video transmission is completed. At the same time, the robot may move according to the design of business logic. route.

At this time, the interfered base station to which the serving cell belongs and the new interferer cell are required. The interfering base station performs interference coordination again, but before that, the user equipment has been subjected to new interference, which affects data transmission and reduces user experience.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to represent examples, illustrations, or descriptions. Any embodiments or designs described as "exemplary" or "such as" in the embodiments of the present invention should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present the related concepts in a specific manner.

The basic idea of inter-cell interference coordination is to coordinate the scheduling and allocation of resources among cells according to certain rules and methods to reduce inter-cell interference. In order to complete the interference coordination between cells in the time domain, the concept of ABS is introduced. For the ABS, only some necessary paging or system message signals are included, and the configured power is very low, so the ABS is configured in the interfering base station to which the interfering cell belongs, and the interfered base station to which the interfered cell belongs is located at the position of these ABSs. Users perform scheduling, thereby realizing inter-cell interference coordination in the time domain. Using the traditional ABS coordination method, when the user equipment moves from one location to another, the serving cell (that is, the interfered cell) is handed over. At this time, the interfered base station to which the serving cell belongs and the new interferer cell are required. The interfering base station performs interference coordination again, but before that, the user equipment has been subjected to new interference, which affects data transmission and reduces user experience.

FIG. 1 shows a scenario diagram of inter-cell interference. As shown in FIG. 1 , it includes an interfered base station 101 , an interferer base station 102 and a user terminal 103 . The coverage area of the interfered base station 101 is the interfered cell 1011 , and the area covered by the interferer base station 102 is the interferer cell 1021 . In the scenario of FIG. 1 , the interfered base station 101 serves the user terminal 103 and provides the user terminal 103 with an interference signal, and the user terminal 103 is interfered by the interferer base station 102 and provides the user terminal 103 with an interference signal. Here, it should be pointed out that although FIG. 1 schematically shows one interfering cell 1021 associated with one interfering base station 102, in other embodiments of the present invention, there may be multiple interfering base stations 102 and associated interference Cell 1021.

Based on the above technical background and the problems existing in the prior art, referring to FIG. 2 , an embodiment of the present invention provides an interference coordination method, which is applied to an interference coordination device, where the interference coordination device is an interfered base station or a chip in the interfered base station, In the following example, the interfered base station performs the method as an example for description, and the method includes:

201. The interfered base station confirms that the user equipment moves from the interfered cell to the interferer cell, then obtains the service type that the user equipment is running, and sends the almost blank subframe ABS pattern set and the service type to the interferer base station; so that the interferer base station confirms according to the service type ABS patterns available in the ABS pattern set.

The signal of the interfering base station covers the interfering cell; the signal of the interfered base station covers the interfered cell.

Optionally, confirming that the interfered base station moves the user equipment from the interfered cell to the interferer cell specifically includes: acquiring a measurement report of the user equipment, and determining that the user equipment moves from the interfered cell to the interferer cell according to the measurement report.

Optionally, acquiring the service type run by the user equipment specifically includes: acquiring service data, and identifying the service type run by the user equipment according to the service data; wherein the service data includes any of the following: a service identifier, a destination IP address of a service data packet , the port number of the service data packet, and the domain name of the service data packet.

Exemplarily, the device that performs the identification of the service type run by the user equipment may be the interfered base station to which the interfered cell belongs, or the MEC server serving the interfered base station. When the MEC server identifies the service run by the user equipment. type, and send the service type run by the user equipment to the interfered base station. The method for identifying the type of service running on the user equipment can be negotiated with the user equipment or the designated service client on the user equipment. When the user equipment starts to perform the specified type of service, the user equipment or the designated service client on the user equipment sends the service to the service. The interfered base station or MEC server of the user equipment sends a specific identifier (such as a service identifier), and the aforementioned interfered base station or MEC server identifies the service type of the user equipment by identifying the identifier; the user equipment can also be analyzed by the interfered base station or MEC server. The destination IP of sending the service data packet, the port number of the service data packet, and the domain name of the service data packet), identify the service type that the user equipment runs. For example, a mobile robot, as a mobile device, according to the negotiation with the MEC server, sends a data packet with a specific identifier to indicate that it will continue to carry out 4K mobile monitoring services in a specific encoding format, and the network bandwidth requirement is about 20Mbps.

In addition, after the interfered base station obtains the measurement report of the user equipment, and determines according to the measurement report that the user equipment moves from the interfered cell to the interferer cell, the method further includes: the interfered base station sends the measurement report and the identifier of the user equipment to the interferer base station, so as to interfere with the interference. The base station confirms, according to the measurement report and the identity of the user equipment, that the service serving cell of the user equipment needs to be handed over from the interfered cell to the interferer cell.

It should be noted that the interfered base station determines that the user needs to be handed over from the interfered cell to the interferer cell after receiving the measurement report of the user equipment according to the conventional handover process. Based on the reciprocity of interference, the user's initial interfered cell is switched to the interferer. In the case of a cell, the one with the strongest interference is generally the current interfered cell. Therefore, when the interfered base station corresponding to the interfered cell sends a handover request message to the interferer base station or mobile core network corresponding to the interfered cell, the interfered base station sends the identity of the user equipment, the service type of the user equipment, and the ABS pattern set that can be used. sent to the interfering base station. The identifier of the user equipment may be information such as the IMEI and IP address of the equipment, which is used to uniquely indicate the user equipment. For example, when the service type of the user equipment is a 4K mobile surveillance service in a specific encoding format, the network bandwidth requirement is about 20 Mbps.

202. The interfered base station receives the ABS pattern returned by the interferer base station.

It should be noted that the interfering base station determines the network resources that need to be configured for the user after switching to the cell according to the obtained service type of the user equipment, the identifier of the user equipment and the user measurement report. For example, the network bandwidth requirement of 20 Mbps requires the interfering base station corresponding to the interfering cell and the interfered base station corresponding to the interfered cell to negotiate to configure 3 ABS blank subframes for the service type of the user equipment; and then according to the interference coordination with other cells and the interfered The allowed ABS pattern set sent by the cell defines the ABS pattern to be used after the user completes handover.

203. After determining that the user equipment is switched from the interfered cell to the interfered cell, the interfered base station performs subframe muting at the corresponding location according to the ABS pattern; so that the interfered base station performs service type data transmission at the corresponding location according to the ABS pattern.

Specifically, after determining that the user equipment is switched from the interfered cell to the interfered cell, the interfered base station performs subframe muting at the corresponding location according to the time set by the ABS pattern, so that the interferer base station performs services at the corresponding location according to the time set by the ABS pattern type of data transfer. For example, the data transmission of a certain service in the service type is performed within the time of xms to yms.

Optionally, when the user equipment completes the handover, that is, after the interfered base station corresponding to the interfered cell receives the user equipment context release message sent from the mobile core network or the interferer base station corresponding to the interferer cell, the interferer cell becomes the serving cell of the user. A data transmission service is provided, and the interfered base station corresponding to the interfered cell and the interferer base station corresponding to the interferer cell perform data transmission or resource scheduling of the service type according to the negotiated ABS pattern.

In the above method, considering that the handover of the serving cell causes the user equipment to suffer new interference; therefore, after confirming that the serving cell of the user equipment has changed from the interfered cell to the interfering cell covered by the signal of the interfering base station, the handover occurs in the serving cell. Before, by sending the ABS pattern set and the service type obtained by the user equipment to the interfering base station; and receiving the interfering base station to confirm the ABS pattern that can be used in the ABS pattern set according to the service type; then determine that the user equipment switches from the interfered cell to the interferer cell. Then, the subframe of the corresponding position is muted according to the ABS pattern; the interfering base station is made to perform data transmission of the service type in the corresponding position according to the ABS pattern, so as to solve the problem that after the switching of the serving cell of the user equipment, the interference coordination is not carried out in time, resulting in new The resulting interference affects the data transmission of the user equipment and reduces the user experience.
