In the fifth generation mobile communication network (The 5Generation Mobile Communication Technology, 5G for short), in order to support a variety of deployment scenarios, the system adapts to the spectrum range from below 1GHz to millimeter wave, 5GNR supports flexible and variable OFDM numerology parameters Set, support flexible frame structure and time slot configuration. The choice of parameter set depends on many factors, including the way of deployment (FDD or TDD), carrier frequency, service requirements (latency, reliability and data rate), mobility, and implementation complexity. For example, the purpose of designing large subcarrier spacing is to support delay-sensitive services (URLLC) and high carrier frequency scenarios, while the purpose of designing small subcarrier spacing is to support low carrier frequency scenarios, large area coverage scenarios, and narrow bandwidth devices. , and enhanced broadcast/multicast (eMBMSs) services. Dynamic time division duplex D-TDD technology came into being.

However, in the current D-TDD technology, different requirements of various services require flexible uplink and downlink time slot allocation, and different uplink and downlink time slot allocations bring serious cross-link interference. In view of the actual situation of this network configuration, the embodiments of the present disclosure solve and alleviate the problems of interference and performance degradation caused by different time slot allocations, and propose a method and device for interference processing for cooperation between base stations, which can effectively reduce cross-linking road interference.

Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of an interference processing method according to an embodiment of the present disclosure. The method includes steps S101 - S103 .

In step S101, the interference time-frequency resource position between the first transmission device and the second transmission device is determined.

In this embodiment, the first transmission device and the second transmission device are base stations, which are gNB1 and gNB2 respectively. Due to the cross-link interference caused by different frame structures and time slots, first determine that the uplink interfered base station gNB1 is the first transmission device , and the base station gNB2 that interferes in the downlink is the second transmission device. As shown in Figure 2, due to the different frame structures of the uplink and downlink, the base station measures the interference in the third time slot, which is the downlink interference of gNB1 to the uplink of gNB2.

Specifically, before step S101, the following steps a-c are also included:

a. Acquire uplink and downlink frame structure configuration information of each transmission device in the preset area.

Specifically, in an area where there is a difference in the configuration of the uplink and downlink time slots, that is, the base stations at the junction of the coverage have an adjacent relationship, acquire and exchange the uplink and downlink frame structure configuration information of the corresponding base station, wherein the uplink and downlink frame structure configuration information Include at least one of the following:

Numerology parameter set, subframe type, slot information, relationship between subframe and slot, relationship between subframe and minislot, relationship between slot and minislot, vacant resource information, resource configuration information, frame structure, carrier information, pattern index number , dynamic resource information and fixed resource information.

b. Identify the uplink interfered transmission device based on the uplink and downlink frame structure configuration information, and determine it as the first transmission device; and,

c. Identifying, based on the configuration information of the uplink and downlink frame structure, the transmission device that emits interference, and determining it as the second transmission device.

According to the configuration information of the uplink and downlink frame structures, that is, the configuration information of the uplink and downlink time slots, determine that the base station that is interfered in the uplink is the first base station, and the base station that emits the interference is the second base station; determine the time slot or time frequency without cross-link interference resources; and time slots or time-frequency resources with cross-link interference; wherein, exemplarily, in a radio frame period of 10ms, base station A’s uplink and downlink time slots are allocated a ratio of 5:5, and base station B’s uplink and downlink time slots are allocated The ratio is 7:3. Base stations A and B are synchronized and aligned at the beginning of the radio frame period. The number of uplink time slots of base station A is 5, which is greater than the number of time slots of adjacent base station B, which is 3. Base station A has two uplink time slots that are strongly interfered by base station B's downlink. Correspondingly, the location of the downlink interference time slot of the base station B can be determined. Base station A is the first base station, and base station B is the second base station.

Further, the interfering cell of the second base station that interferes with the receiver of the first base station can be determined according to the adjacent cells or the adjacent relationship covered by the cell of the base station. Wherein, for the cell with interference in the uplink of the first base station, it is a cell in the adjacent second base station facing the first base station in the antenna coverage direction. In some embodiments, the first base station may also perform uplink time slot interference monitoring to determine the second base station and cell from which the downlink signal of the base station interferes.

In step S102, the uplink time-frequency resource and the downlink time-frequency resource are allocated according to a preset ratio on the interference time-frequency resource position; and,

In step S103, service data is transmitted based on the uplink time-frequency resource and the downlink time-frequency resource at the position of the interference time-frequency resource, respectively.

In this embodiment, when data is sent on resources with interference, corresponding uplink and downlink time-frequency resources are allocated according to a preset ratio—the ratio of resource requirements, which may be staggered in time domain or frequency domain. Specifically, the preset ratio is calculated according to the following formula:

In the above formula, H represents a preset ratio, and the RLC (Radio Link Control Process, radio link control layer) downlink buffer data volume is the downlink buffer data volume obtained by the base station side, and in some embodiments, it may also be PDCP (Packet Data Convergence Protocol, packet data convergence protocol) buffer data volume, the base station side obtains the buffer data volume; BSR uplink buffer data volume is the uplink buffer data volume reported by the UE side, specifically, the BSR (Buffer Status Report, buffer status reported by the UE side) report) buffer data amount; N1 is the buffer time threshold in the downlink direction, M1 is the data volume threshold in the downlink direction, M2 is the buffer time threshold in the uplink direction, and R is the selected allocation coefficient.

It can be understood that, in this embodiment, the downstream direction, the buffered data volume threshold M1, and the buffering time threshold N1 are preset; and the upstream direction, the buffered data volume threshold M2, and the buffering time threshold N2 are preset.

In some embodiments, uplink and downlink data transmission is preferentially performed on non-interference resources. Obtain the buffer information of uplink data scheduled by the first base station in the non-interference time slot, including the buffer size and the average buffer duration; obtain the buffer information of the downlink data scheduled by the second base station in the non-interference time slot, including the buffer size and the average buffer duration. If the buffered information is higher than the threshold, then according to the preset proportional relationship, different time-frequency resources are occupied to transmit in the interference time slot.

In the related art, in order to solve the problem of duplex link interference, various configuration and scheduling information related to uplink and downlink resource allocation of adjacent base stations are collected and exchanged. resources, or by reducing power, and performing operations such as resource staggering for transmission. The purpose is to completely dynamically allocate uplink and downlink resources and flexibly duplex to avoid interference. In order to realize flexible dynamic duplexing in the above-mentioned related technologies, it is necessary to coordinate related resources such as time-frequency space domain, etc., which is complicated to implement, difficult to implement in equipment, and cannot be supported by an actual network. In practical applications, the time slot configuration generally adopts a semi-static configuration of different time slots and a method of dynamically scheduling time-frequency resources.

Compared with the above-mentioned related art, this embodiment determines the interference time-frequency resource positions between base stations according to the actual situation of the network configuration, and allocates the upper and lower time-frequency resources according to a preset ratio, wherein the preset ratio is based on the uplink and downlink buffers seen by the base stations. Information such as data volume and cache duration are calculated and obtained, and then the time-frequency resources with cross-interference are used to transmit service data, so as to solve and alleviate the problems of interference and performance deterioration caused by different time slot ratios. The lower one is a scheme of cooperation between base stations, which effectively reduces the interference of cross-links.

Please refer to FIG. 3 . FIG. 3 is a schematic flowchart of an interference processing method provided by another embodiment of the present disclosure. On the basis of the previous embodiment, in this embodiment, the time-frequency of non-interference resources is preferentially scheduled, and the uplink and downlink buffer information are both scheduled. When a certain limit is exceeded, different time-frequency resources are occupied on the interference resources for data transmission to further reduce the scheduling complexity and improve the user experience. Specifically, the interference between the first transmission device and the second transmission device is determined. After the time-frequency resource position (step S101); and before allocating uplink time-frequency resources and downlink time-frequency resources according to a preset ratio on the interference time-frequency resource position (step S102), the following steps are also included:

In step S301, determine a non-interference time-frequency resource location between the first transmission device and the second transmission device;

In step S302, obtain first buffer information scheduled by the first transmission device at the non-interference time-frequency resource location, where the first buffer information includes a first buffer data amount and a first buffer average duration;

In step S303, obtain second buffer information scheduled by the second transmission device at the non-interference time-frequency resource location, where the second buffer information includes the second buffer data volume and the second buffer average duration;

In step S304, it is determined whether the first buffered data volume is greater than the preset first buffered data volume threshold, and whether the average first buffered duration is greater than the preset first time threshold, and if so, execute the step S305, otherwise, step S306 is executed.

In step S305, it is determined whether the amount of the second cached data is greater than a preset threshold, the preset threshold is calculated based on the preset second cache threshold and the preset second time threshold, if the If the second amount of buffered data is greater than the preset threshold, step S102 is performed to allocate uplink time-frequency resources and downlink time-frequency resources at the interference time-frequency resource position according to a preset ratio, otherwise, step S306 is performed.

It should be noted that, in some embodiments, step S304 and step S305 may be performed simultaneously, or step S305 is performed first and then step S304 is performed. This embodiment only provides an exemplary manner, which is not limited thereto.

In step S306, skip the step of allocating uplink time-frequency resources and downlink time-frequency resources according to a preset ratio at the interference time-frequency resource positions, and transmit service data at the non-interference time-frequency resource positions.

The first transmission device is the transmission device that is interfered in the uplink, and the second transmission device is the transmission device that interferes in the downlink.

Specifically, firstly compare the first buffered information and the second buffered information with the set thresholds. If the information is lower than the threshold, continue to send in the non-interference time slot, and if it is higher than the threshold, it will be scheduled in the interference time slot; If all of them are higher than the threshold, then according to a certain proportional relationship, different time-frequency resources are occupied to transmit in the interference time slot.

Specifically, set the downlink direction, the buffered data volume threshold M1, and the buffering time threshold N1; set the uplink direction, the buffered data volume threshold M2, and the buffering time threshold N2;

Among them, for the downlink direction, if the following judgment criteria are met, it is sent on the interference resource; otherwise, it is only sent on the non-interference resource:

RLC downlink buffer data volume>max(RLC air interface rate*N1, M1)

For the uplink direction, if the amount of buffered data reported by the terminal side BSR (buffer status report) is greater than M2, and the duration is greater than N2, it is determined that the threshold is exceeded, and it is sent on the resource with interference; otherwise, it is only sent on the resource without interference.

If both the uplink and downlink directions exceed the threshold, when data is sent on the interfering resources, the uplink and downlink time-frequency resources are allocated according to the ratio of resource requirements, and the transmission can be staggered in the time domain or frequency domain.

For example, radio resources such as time and frequency may be allocated according to the following proportions.
