Description

Interference coordination method and device, and base station

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to an interference coordination method, an interference coordination device and a base station.

Background

The 5G network supports 1000-time magnitude increase of traffic, the core technology is to deploy an ultra-dense network, and the cell radius is reduced by increasing the number of low-power sites so as to improve the transmission capability of unit area and improve the system capacity. In an ultra-dense network scene, the deployment density of stations is increased, and the distance between stations is reduced, which leads to more serious inter-cell interference. At the cell edge, the user rate and experience are difficult to be effectively improved. And as the number of neighboring stations increases, there may be multiple interferers of close strength, making the interference situation more complex. How to avoid inter-cell interference through site cooperation is an important problem to be solved by ultra-dense networks.

In time domain inter-cell interference coordination in an ultra-dense networking scene, it is necessary to determine an Almost Blank Subframe (ABS) pattern used by an interfering base station to which an interfering cell belongs and an interfered base station to which an interfered cell belongs. In a traditional mode, after an interfered base station discovers an interfering base station for a certain user, a time domain inter-cell interference coordination request is sent to the interfering base station according to the network quality condition fed back by the user, then the interfering base station sends an ABS pattern set to the interfered base station, the interfered base station selects an ABS pattern and feeds back the ABS pattern to the interfering base station for confirmation, and then resource scheduling is carried out based on the confirmed pattern; or the interfered base station directly sends an ABS pattern set to the interfering base station, and after the interfering base station selects one ABS pattern, the interfering base station and the interfered base station carry out resource scheduling based on the confirmed pattern. However, with the rapid development of mobile internet services and the rise of 5G + industry vertical services, there gradually appears a service type in which the demand for a network is regularly changed. For example, in a mobile network video on demand service, a user terminal generally opens a video playing page and initiates DNS query and signaling interaction, and the data transmission rate requirement at this stage is low; and then, the transmission and playing of the video data are completed, and the data transmission rate requirement at this stage is high. By using the conventional ABS negotiation method, when the transmission rate requirement changes, the originally negotiated ABS pattern can not meet the latest requirement very much, and then the negotiation needs to be performed again, so that the efficiency of interference coordination is low.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and 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 indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

It should be noted that, in the embodiments of the present invention, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that, when the difference is not emphasized, the intended meaning is consistent.

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 accomplish interference coordination between cells in 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 that 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 schedules the user at the position of these ABSs, thereby implementing inter-cell interference coordination in the time domain.

In a traditional ABS interference coordination mode, after an interfered base station finds an interfering base station for a certain user, a time domain inter-cell interference coordination request is sent to the interfering base station according to the network quality condition fed back by the user, then the interfering base station sends an ABS pattern set to the interfered base station, the interfered base station selects an ABS pattern and feeds back the ABS pattern set to the interfering base station for confirmation, and then resource scheduling is carried out based on the confirmed pattern; or the interfered base station directly sends an ABS pattern set to the interfering base station, and after the interfering base station selects one ABS pattern, the interfering base station and the interfered base station carry out resource scheduling based on the confirmed pattern. However, with the rapid development of mobile internet services and the rise of 5G + industry vertical services, there gradually appears a service type in which the demand for a network is regularly changed. For example, in a mobile network video on demand service, a user terminal generally opens a video playing page and initiates DNS query and signaling interaction, and the data transmission rate requirement at this stage is low; and then, the transmission and playing of the video data are completed, and the data transmission rate requirement at this stage is high. By using the conventional ABS negotiation method, when the transmission rate requirement changes, the originally negotiated ABS pattern can not meet the latest requirement very much, and then the negotiation needs to be performed again, so that the efficiency of interference coordination is low.

Fig. 1 shows a scenario diagram of inter-cell interference. As shown in fig. 1, includes: the interfered base station 101, the interfering base station 102 and the user terminal 103 are configured such that the coverage area of the interfered base station 101 is an interfered cell 1011 and the coverage area of the interfering base station 102 is an interfering cell 1021. In the scenario of fig. 1, the interfered base station 101 serves the user terminal 103 to provide an interference signal to the user terminal 103, and the user terminal 103 is interfered by the interfering base station 102 to provide an interference signal to the user terminal 103. Here, it is to be noted that although one interfering cell 1021 associated with one interfering base station 102 is schematically shown in fig. 1, in other embodiments of the present invention, there may be a plurality of interfering base stations 102 and associated interfering cells 1021.

Based on the problems 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 apparatus, where the interference coordination apparatus is an interference base station or a chip in the interference base station, and the following example takes the interference base station to execute the method as an example to describe, where the method includes:

201. and the interfering base station receives the user traffic sent by the interfered base station and the ABS configuration requirement of the almost blank subframe.

For example, the user service is mainly identified by the interfered base station, and the device for executing the user service identification operation may be a base station to which the interfered base station belongs, or an MEC server serving the base station to which the interfered base station belongs. The method for identifying the user service can be through consulting with the user terminal or the appointed service client on the user terminal, when the user terminal starts to carry out the appointed service, the appointed service client on the user terminal or the user terminal sends an appointed mark to the base station serving the user, and the base station or the MEC server identifies the user service through the mark; or the base station or the MEC server can analyze the information such as IP, port number or domain name and the like in the destination of the data packet sent by the user terminal to identify the user service. For example, for a mobile network video on demand service, the MEC server parses domain name information in a Domain Name System (DNS) request initiated by a user, and identifies the mobile network video on demand service with a service type of 4K bit rate for the user.

In addition, the ABS configuration requirement may contain information such as the number of currently required ABS, the location where ABS is not allowed to be configured, and the location where ABS needs to be configured. For example, an ABS configuration requirement for mobile network video on demand service may include that n ABS are currently required and that ABS is not allowed to be configured in location 1.

202. And the interference base station predicts the requirements of different user service types on the network bearing capacity in the next preset time period according to the user service.

Optionally, when the user service is a video-on-demand service, step 102 specifically includes: the interference base station predicts the network bandwidth requirements of domain name system DNS query, signaling interaction, video data transmission and video data playing in the corresponding transmission time respectively in the next preset time period according to the video on demand service; wherein the requirement of the network bearer capability comprises a network bandwidth requirement at a corresponding transmission time.

It should be noted that, the interference base station predicts the requirements of different user service types on the network carrying capacity in the next preset time period according to the user service, specifically, determines the requirements of different user service types on the network carrying capacities such as bandwidth, delay, bit error rate and the like when executing the user service in the next preset time period according to the user service types. For example, for a video on-demand service of a mobile network, a user terminal generally opens a video playing page and initiates DNS query, then completes signaling interaction such as TCP link establishment, and finally starts to complete video transmission and playing. When a user terminal carries out DNS query service, the transmitted data volume is small, the requirement on network bandwidth is low, and an interference base station predicts that the network bandwidth required by the user terminal is a Mbps and continuously transmits the data for x ms; when the user terminal carries out the service of initial signaling interaction, the transmitted data volume is small, the requirement on the network bandwidth is low, and the interference base station predicts that the network bandwidth required by the user terminal is b Mbps and continuously transmits y ms; when the user terminal carries out video data transmission, the transmitted data volume is large, the requirement on the network bandwidth is high, the interference base station predicts the network bandwidth required by the user terminal to be c Mbps according to the 4K code rate of the video requested by the user terminal, and the video data is continuously transmitted for at least z ms.

203. The interference base station makes a time-varying ABS pattern list of the next preset time period according to the requirement of the user service type on the network bearing capacity and the ABS configuration requirement, and sends the time-varying ABS pattern list to the interfered base station, so that the interfered base station transmits data corresponding to the user service type at the corresponding position of the preset time in the next preset time period according to the time-varying ABS pattern list.

For example, the time-varying ABS pattern list may include ABS configuration results generated according to corresponding transmission time and network bandwidth requirements when different user traffic types are executed within a next preset time period.

Optionally, the interfering base station may make a time-varying ABS pattern list of a next preset time period according to a requirement of the user service type on the network carrying capacity and an ABS configuration requirement, where the time-varying ABS pattern list specifically includes:

and S1, the interference base station determines the ABS position where the user service type is not allowed to be configured in the next preset time period and the ABS quantity needing to be configured according to the ABS configuration requirement.

And S2, the interfering base station makes a time-varying ABS pattern list of the next preset time period according to the position of the ABS which is not allowed to be configured, the number of the ABS which needs to be configured and the requirement of the network bearing capacity.

In addition, after the interfering base station makes a time-varying ABS pattern list for the next preset time period according to the requirement of the user service type on the network carrying capacity and the ABS configuration requirement, the method further includes: and the interference base station performs subframe silencing at the corresponding position of the preset time in the next preset time period according to the time-varying ABS pattern list.

It should be noted that subframe muting means that ABS allocated at a position corresponding to a preset time within a next preset time period is only used for transmitting data corresponding to a specific user service type in an interfered base station, and other user services cannot be used.

Optionally, the interfering base station determines, according to the received ABS configuration requirement, the ABS location that is not allowed to be configured in the next preset time period and the number of ABSs that need to be configured, and determines, based on the requirement conditions of different user service types to the network carrying capacity predicted in step 102, a time-varying ABS pattern list that should be changed in time correspondingly after the current and subsequent changes with the user service requirement. For example, for the mobile video-on-demand service in step 202, when the user terminal opens a video playing page and initiates DNS query, the interfering base station predicts that the network bandwidth required by the user terminal is a Mbps, and will transmit continuously for x ms; when the user terminal carries out the service of initial signaling interaction, the interference base station predicts that the network bandwidth required by the user terminal is bMbps and continuously transmits y ms; when the user terminal carries out video data transmission, the interference base station predicts the network bandwidth required by the user terminal to be c Mbps for 4K code rate according to the video requested by the user terminal, and continuously transmits the data for at least z ms. Combining the above, the ABS pattern is designed to configure the position 2 to the position 1+ n as ABS within x ms; when an initial signaling interaction service is started later, according to the network bandwidth requirement of b Mbps, it is estimated that m ABS are needed to ensure the transmission quality, and then ABS patterns are designed to be configured as ABS from the position 2 to the position 1+ m within the time from (x +1) ms to (x + y) ms; then, starting video service data transmission, and predicting that q ABS are needed to ensure transmission quality according to the bandwidth requirement of c Mbps, designing an ABS pattern to configure positions 2 to 1+ q as ABS within the time from (x + y +1) ms to (x + y + z) ms, that is, a subsequent time-varying ABS pattern list of (x + y + z) ms specifically includes: within x ms, the ABS pattern is configured to be ABS from position 2 to position 1+ n; within (x +1) ms to (x + y) ms, the ABS pattern configures all of position 2 to position 1+ m as ABS; within (x + y +1) ms to (x + y + z) ms, the ABS pattern configures each of position 2 to position 1+ q as an ABS.

In addition, the interfering base station performs subframe silencing at a position corresponding to a preset time in a next preset time period according to the time-varying ABS pattern list, and the interfered base station performs data transmission corresponding to a user service type at a position corresponding to a preset time in a next preset time period according to the time-varying ABS pattern list, which supports the above example, and the specific implementation manner includes: within x ms, the subframe from the position 2 to the position 1+ n of the interfering base station is silenced, and the interfered base station allocates resources for the user terminal at the corresponding position so as to complete data transmission; within (x +1) ms to (x + y) ms, the subframe of the interference base station from the position 2 to the position 1+ m is silenced, and the interfered base station allocates resources for the user terminal at the corresponding position so as to complete data transmission; and within (x + y +1) ms to (x + y + z) ms, the subframes from the position 2 to the position 1+ q of the interference base station are silenced, and the interfered base station allocates resources for the user terminal at the corresponding position so as to complete data transmission.

The embodiment of the present invention may perform functional module division on the interfering base station according to the method embodiment, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated in one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode.

In an exemplary scheme, the processing unit 302 is specifically configured to determine, according to the ABS configuration requirement received by the receiving unit 301, an ABS location where a user service type is not allowed to be configured in a next preset time period and a number of ABSs that need to be configured;

the processing unit 302 is further configured to customize a time-varying ABS pattern list for a next preset time period according to the configured ABS location, the number of ABS needing to be configured, and the network carrying capacity requirement.
