• Step 4 The eNB sends a measurement task to UE2, and measures cells on G and ⁇ , f4;
• Step 5 The UE2 performs the measurement and reports the measurement report.
• the Cell2 on the G meets the reporting condition and reports it to the eNB.
• the Cell3 on the ⁇ also satisfies the reporting condition and is also reported to the eNB.
• the Cell4 on the f4 also satisfies the reporting condition. Also reported to the eNB;
• Step 6 The eNB finds that UE2 supports carrier aggregation between frequency bands 33, 34, 35, and 36 according to the capability of UE2, but does not support aggregation of TDD cells with different subframe configurations when frequency bands 33, 34 and frequency band 36 are aggregated, nor Supports simultaneous transmission and reception in the same sub-frame. Others support it. Therefore, only the Cell2 configured on UE2 and the Cell3 on ⁇ are aggregated and configured to UE2 through the RRC reconfiguration command. In this embodiment, the base station, according to the capability information reported by the terminal (Table 5-2), concludes that when the frequency bands 33, 34, 35, 36 are aggregated, the terminal does not support the TDD cells with different subframe configurations for aggregation.
