Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way limits the present invention and its application or use.

[0034] For technologies, methods, and devices known to those of ordinary skill in the relevant art, detailed discussions may not be made, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorization specification.

[0035] In all the examples shown and discussed here, any specific value should be construed as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0037] Figure 1The flowchart shows a communication control method according to some embodiments of the present invention. As Figure 1 shown, the communication control method of this embodiment includes steps S102 to S108. Steps S102 to S106 are executed on the DSS base station side.

[0038] In step S102, identify the location of an NR (New Radio) terminal in the connected state. The NR terminal accesses the DSS base station.

[0039] In some embodiments, based on the reporting events of the NR terminal (such as A3, A4, A5 events) and the neighbor cell relationship, determine the location of the NR terminal. For example, the A3 event indicates that the measurement result of the neighbor cell is better than that of the serving cell. Combining the signal quality of each cell in the neighbor cell relationship, the location of the NR terminal can be determined.

[0040] In step S104, in response to identifying that the new radio NR terminal in the connected state moves to the boundary of the coverage areas of the DSS base station and the LTE (Long Term Evolution) base station, determine the resource occupancy information of the NR terminal.

[0041] In some embodiments, the resource occupancy information includes the uplink PRB (Physical Resource Block) index number, the downlink PRB index number, and the scheduling timing information.

[0042] In some embodiments, the LTE base station does not support DSS.

[0043] In some embodiments, the LTE base station and the DSS base station are networked through a hybrid networking method. Thus, this embodiment can reduce interference on the premise of reducing the networking construction cost.

[0044] In step S106, send an intelligent scheduling request to the LTE base station, where the intelligent scheduling request includes the resource occupancy information of the NR terminal.

[0045] In some embodiments, the DSS base station sends an intelligent scheduling request to the LTE base station through the NG interface. The NG interface is the interface between the radio access network and the 5G core network.

[0046] In step S108, the LTE base station adjusts the resource configuration of the LTE base station according to the intelligent scheduling request, so that the adjusted resource configuration avoids the resources occupied by the NR terminal.

[0047] For example, the LTE base station adjusts the scheduling timing pattern of the LTE base station, so that the LTE base station performs avoidance scheduling on the uplink and downlink PRBs occupied by the NR terminal and the scheduling timing, thereby effectively eliminating the uplink and downlink interference between the NR terminal and the LTE base station.

[0048] In some embodiments, after the adjustment, the LTE base station sends the adjustment result of the resource configuration to the DSS base station. If the LTE base station is unable to make an adjustment or the adjustment fails, the LTE base station can also inform the DSS base station of the result so that the DSS base station can take other measures.

[0049] Through the method of the above embodiments, in the scenario of the DSS base station and the LTE base station networking, when the terminal moves to the coverage boundary of the two, which may cause uplink and downlink interference, the DSS base station informs the LTE base station of the resource occupancy information of the NR terminal, so that the LTE base station can adaptively adjust its own resource configuration to avoid the resources occupied by the NR terminal. Without wasting the PRB resources of the DSS and LTE base stations, the above embodiments greatly improve the networking flexibility and resource utilization rate, and reduce the uplink and downlink interference. And in the case of the hybrid networking of the LTE base station and the DSS base station, the construction cost in the initial stage of building the 4G / 5G DSS network is reduced.

[0050] Table 1 exemplarily shows the situation of the PRBs occupied by a certain NR terminal. The underlined part indicates the PRB resources occupied by the NR terminal.

[0051] Table 1

[0052]

[0053] After the DSS base station sends this information to the LTE base station, the LTE base station can perform avoidance scheduling. For example, the LTE base station uses the resource configuration in Table 2 for scheduling.

[0054] Table 2

[0055]

[0056] It can be seen that through adaptive scheduling, the LTE base station can avoid the resources occupied by the NR terminal and reduce the uplink and downlink interference.

[0057] In some embodiments, a new signaling can be added between the DSS base station and the LTE base station to enable their interaction. The following refers to Figure 2 Describe the embodiments of the communication control method of the present invention.

[0058] Figure 2 Shows a schematic flowchart of a communication control method according to other embodiments of the present invention. AsFigure 2 As shown, the communication control method of this embodiment includes steps S202 to S208.

[0059] In step S202, in response to identifying that a New Radio (NR) terminal in the connected state moves to the boundary of the coverage areas of a Dynamic Spectrum Sharing (DSS) base station and a Long-Term Evolution (LTE) base station, the DSS base station determines the resource occupancy information of the NR terminal.

[0060] In step S204, the DSS base station sends an Adaptive Scheduling Request (ASR, hereinafter referred to as) to the LTE base station via the NG interface. The adaptive scheduling request includes an intelligent scheduling request, and the intelligent scheduling request includes the resource occupancy information of the NR terminal.

[0061] In step S206, the LTE base station adjusts the resource configuration of the LTE base station according to the intelligent scheduling request, so that the adjusted resource configuration avoids the resources occupied by the NR terminal.

[0062] In step S208, the LTE base station receives an adaptive adjustment response sent by the LTE base station via the NG interface. The adaptive adjustment response includes the adjustment result of the resource configuration of the LTE base station.

[0063] The method of the above embodiment adds signaling based on the NG interface. Through the newly added adaptive scheduling request and adaptive adjustment response, the DSS base station and the LTE base station can implement an adaptive adjustment scheme for reducing uplink and downlink interference.
