To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, specific embodiments of the present disclosure are described below in detail with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In a fifth Generation Mobile Communication network (5G for short), The system adapts to a spectrum range from below 1GHz to mm-wave in order to support a wide variety of deployment scenarios, and The 5G NR supports a flexible and variable OFDM numerology parameter set, supporting a flexible frame structure and slot allocation. The choice of parameter set depends on many factors including the way of deployment (FDD or TDD), carrier frequency, traffic requirements (delay, reliability and data rate), mobility, and implementation complexity. For example, large subcarrier spacing is designed to support delay sensitive services (URLLC) and high carrier frequency scenarios, while small subcarrier spacing is designed to support low carrier frequency scenarios, large coverage scenarios, narrow bandwidth devices, and enhanced broadcast/multicast (embmbs). Dynamic time division duplex (D-TDD) technology is available.
However, in the current D-TDD technology, different requirements of multiple services require flexible uplink and downlink timeslot matching, and different uplink and downlink timeslot matching brings severe cross link interference. The embodiments of the present disclosure provide an interference processing method and apparatus for cooperation between base stations, which can effectively reduce interference of a cross link, for solving and reducing the interference and performance degradation caused by different timeslot ratios in the actual situation of the network configuration.
Referring to fig. 1, fig. 1 is a flowchart illustrating an interference processing method according to an embodiment of the present disclosure, where the method includes steps S101 to S103.
In step S101, the interference time-frequency resource location 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 respectively a gNB1 and a gNB2, and due to cross link interference caused by different frame structure timeslots, it is first determined that the uplink interfered base station gNB1 is the first transmission device, and the downlink interfering base station gNB2 is the second transmission device, as shown in fig. 2, due to different uplink and downlink frame structures, interference measured by the base station is interference of downlink of the gNB1 on uplink of the gNB2 on the third timeslot.
Specifically, before step S101, the following steps a-c are further included:
a. and acquiring the configuration information of the uplink and downlink frame structures of each transmission device in a preset area.
Specifically, configuring areas with differences in uplink and downlink time slots, that is, base stations at covered junctions have an adjacent relationship, and acquiring and exchanging uplink and downlink frame structure configuration information of corresponding base stations, where the uplink and downlink frame structure configuration information includes at least one of the following:
numerology parameter set, subframe type, slot information, subframe-to-slot relationship, subframe-to-small-slot relationship, slot-to-small-slot relationship, idle resource information, resource configuration information, frame structure, carrier information, pattern index number, dynamic resource information, and fixed resource information.
b. Identifying the transmission equipment interfered by the uplink based on the configuration information of the uplink and downlink frame structures, and determining the transmission equipment interfered by the uplink as first transmission equipment; and (c) a second step of,
c. and identifying the transmission equipment which sends interference based on the configuration information of the uplink and downlink frame structures, and determining the transmission equipment as second transmission equipment.
Determining the base station with the uplink interference as a first base station and determining the base station sending the interference as a second base station according to the configuration information of the uplink and downlink frame structures, namely the configuration information of the uplink and downlink time slots; determining time slots or time frequency resources without cross link interference; and time slot or time frequency resource with cross link interference; in an exemplary embodiment, in a radio frame period of 10ms, the uplink and downlink timeslot ratio of the base station a is 5: 5, the ratio of uplink time slots and downlink time slots of the base station B is 7: 3. the starting positions of the wireless frame periods of the base stations A, B are aligned synchronously, the number of uplink time slots of the base station A is 5 and is larger than the number of time slots of the adjacent base station B by 3, and two uplink time slots of the base station A are strongly interfered by the downlink of the base station B. Accordingly, the position of the downlink interference timeslot of the base station B can be determined. The base station a is a first base station and the base station B is a second base station.
Further, an interfering cell of the second base station, which interferes with the first base station receiver, may be determined according to a neighboring cell or a neighboring relationship covered by the base station cell. The cell with interference on the uplink of the first base station is a cell facing the first base station in the antenna coverage direction in the adjacent second base station. In some embodiments, the second base station and the cell from which the downlink signal interference of the base station comes are also determined by performing uplink timeslot interference monitoring at the first base station.
In step S102, allocating uplink time-frequency resources and downlink time-frequency resources at the interference time-frequency resource position according to a preset ratio; and the number of the first and second groups,
in step S103, service data is transmitted based on the uplink time-frequency resource and the downlink time-frequency resource at the interference time-frequency resource location, respectively.
In this embodiment, when data is sent on an interfered resource, corresponding uplink and downlink time-frequency resources are allocated according to a preset ratio, that is, a ratio of resource requirements, and the data can be sent in a staggered manner in a time domain or a frequency domain. Specifically, the preset proportion 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 amount is a downlink buffer Data amount acquired by the base station side, and in some embodiments, may also be a PDCP (Packet Data Convergence Protocol) buffer Data amount, and the base station side acquires the buffer Data amount; the BSR uplink Buffer data volume is an uplink Buffer data volume reported by the UE side, and specifically, the BSR (Buffer Status Report) Buffer data volume reported by the UE side; n1 is a downlink buffering time threshold, M1 is a downlink data amount threshold, M2 is an uplink buffering time threshold, and R is a selected distribution coefficient.
It can be understood that, in this embodiment, the downlink direction, the buffer data amount threshold M1, and the buffer time threshold N1 are preset; and presetting an uplink direction, a buffer data volume threshold M2 and a buffer time threshold N2.
In some embodiments, upstream and downstream data transmissions are prioritized over non-interfering resources. Acquiring uplink data caching information including caching size and caching average duration scheduled by a first base station in an interference-free time slot; and acquiring downlink data caching information including caching size and caching average duration scheduled by the second base station in the non-interference time slot, and when the uplink and downlink data caching information is higher than a threshold, occupying different time-frequency resources to transmit in the interference time slot according to a preset proportional relation.
In the related art, in order to solve the problem of duplex link interference, various configurations and scheduling information related to uplink and downlink resource allocation of adjacent base stations are mainly collected and exchanged, and according to the conditions of resource allocation and interference detection, the related resources are staggered (vacant), or power is reduced, and other means are performed to perform operations such as resource staggering and the like for transmission. In order to realize flexible dynamic duplex, the related technologies need to coordinate resources such as a time-frequency space domain and the like, and have high realization complexity, difficult equipment realization and incapability of being supported by an actual network. In practical application, the time slot configuration generally adopts different semi-static time slot configurations and a mode of dynamically scheduling time frequency resources.
Compared with the related art, the embodiment determines the interference time-frequency resource position between the base stations according to the actual situation of the network configuration, allocates the upper and lower time-frequency resources according to the preset proportion, wherein the preset proportion is calculated and obtained based on the information of the uplink and downlink buffer data amount, the buffer duration and the like seen by the base stations, and then uses the time-frequency resources with cross interference to transmit the service data, so as to solve and reduce the interference and performance deterioration problems caused by different time slot ratios.
Referring to fig. 3, fig. 3 is a schematic flow chart of an interference processing method according to another embodiment of the present disclosure, in the above embodiment, the embodiment preferentially schedules time and frequency of an interference-free resource, and when uplink and downlink cache information both exceed a certain limit, then occupies different time and frequency resources on the interference resource to perform data transmission, so as to further reduce scheduling complexity and improve user experience, specifically, after determining an interference time and frequency resource position between a first transmission device and a second transmission device (step S101); and before allocating the uplink time-frequency resource and the downlink time-frequency resource according to the preset proportion at the interference time-frequency resource position (step S102), the method further comprises the following steps:
in step S301, determining a location of an interference-free time-frequency resource between the first transmission device and the second transmission device;
in step S302, first buffer information scheduled by the first transmission device at the non-interference time-frequency resource location is obtained, where the first buffer information includes a first buffer data size and a first buffer average duration;
in step S303, second cache information scheduled by the second transmission device at the non-interference time-frequency resource location is obtained, where the second cache information includes a second cache data amount and a second cache average duration;
in step S304, it is determined whether the first buffer data amount is greater than a preset first buffer data amount threshold, and whether the first buffer average duration is greater than a preset first time threshold, if so, step S305 is executed, otherwise, step S306 is executed.
In step S305, it is determined whether the second cache data amount is greater than a preset threshold, where the preset threshold is calculated based on a preset second cache threshold and a preset second time threshold, if the second cache data amount is greater than the preset threshold, step S102 is executed 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 executed.
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, and this embodiment only provides an example manner, and does not limit this.
In step S306, a step of allocating uplink time-frequency resources and downlink time-frequency resources at the interference time-frequency resource position according to a preset ratio is skipped, and service data is transmitted at the interference-free time-frequency resource position.
The first transmission device is an uplink interfered transmission device, and the second transmission device is a downlink interference-emitting transmission device.
Specifically, first, comparing the first buffer information and the second buffer information with a set threshold respectively, if the first buffer information and the second buffer information are lower than the threshold, continuing to transmit in an interference-free time slot, and if the first buffer information and the second buffer information are higher than the threshold, scheduling in an interference-free time slot; if both are higher than the threshold, then according to a certain proportional relation, different time frequency resources are occupied for transmitting in the interference time slot.
Specifically, a downlink direction, a buffer data volume threshold M1 and a buffer time threshold N1 are set; setting an uplink direction, a buffer data volume threshold M2 and a buffer time threshold N2;
for the downlink direction, if the following judgment standard is met, sending on the interference resource; otherwise, only transmitting on non-interfering resources:
RLC downlink buffer data volume > max (RLC idle rate N1, M1)
For the uplink direction, if the buffer data volume of the BSR (buffer status report) reported by the terminal side is greater than M2 and the duration is greater than N2, the terminal side determines that the buffer data volume exceeds the threshold and sends the buffer data on the interfered resources; otherwise, only transmitting on non-interference resources.
If the uplink and downlink directions both exceed the threshold, when data is transmitted on the resource with interference, the uplink and downlink time-frequency resources are allocated according to the proportion of resource requirements, and staggered transmission can be performed on a time domain or a frequency domain.
