[0037] Existing carrier aggregation solutions are based on the way that network control nodes such as base stations (in LTE systems, eNBs, for example) participate in scheduling, that is, various behaviors of carrier aggregation performed by the base station, such as related measurement, decision-making, and event triggering Scheduling, this mode of carrier aggregation is referred to as base station scheduling mode hereinafter. Moreover, the current carrier aggregation communication is mainly applied to the link between the network control terminal and the network node, such as Uulink.
[0038] However, as mentioned above, in the sidelink scenario where network nodes communicate directly with network nodes, the communication between network nodes can be done without the participation of network control nodes. Therefore, in the case of using carrier aggregation for communication, the existing carrier aggregation Various behaviors may not be performed correctly. In view of this...

[0083] An example in which the electronic device 100 is located on the network control node side will be described in this embodiment. According to this example, the configuration of the PCC and the SCC is performed by the network control node, that is, the scheduling mode is performed by the network control node that performs related operations of carrier aggregation, which is applicable to the IC scenario.
[0084]In this mode, the network control node selects and configures the PCC as described above, and periodically sends measurement events to the network nodes through the PCC, and the measurement period is configured by high-level signaling, for example. The network nodes perform measurement operations on the respective available CCs, for example, measure parameters of the communication quality of the respective available CCs. Similarly, parameters indicating communication quality of available CCs may include signal strength information on corresponding CCs. For example...

[0093] As mentioned above, due to the movement of network nodes, mutual switching between OCC scenarios and IC scenarios may occur, such as Figure 13 with 14 shown. in, Figure 13 shows the switching from the OOC scene to the IC scene, Figure 14 shows the switching from the IC scene to the OOC scene.
[0094] In the case that the first network node and the second network node are currently in OOC, the judging unit 101 of the electronic device 100 may also be configured to judge whether the first network node and the second network node have moved within the coverage of the network control node, And if it is judged as yes, the configuration unit 102 negotiates with the second network node whether to transfer decision-making operations related to carrier aggregation to the network control node, and if it is judged as no, continue the current carrier aggregation operation. In other words, when switching from OOC to IC occurs, the communication parties negotiate to decide wh...
