Method and device for terminal to report MTA (multiple time advance) capacity in carrier aggregation system

[0052]In this example, if figure 2 and image 3 As shown, it is assumed that f1 and f2 belong to frequency band 1, f3 belongs to frequency band 3, the cell on f1 is Cell1, the cell on f2 is Cell2, and the cell on f3 is Cell3. The specific steps are described as follows:

[0053] Step 1: UE1 enters the connection state through Cell1 in the eNB;

[0054] Step 2: The eNB initiates a capability query process to UE1, and UE1 reports that it supports carrier aggregation of frequency band 1 and frequency band 1, carrier aggregation of frequency band 1 and frequency band 3, and an MTA that supports carrier aggregation of the same frequency band at the same time, and an MTA that does not support carrier aggregation of different frequency bands;

[0055] Step 3: UE1 moves into the coverage of RRH and repeater. Due to the increase of traffic, eNB decides to configure carrier aggregation;

[0056] Step 4: eNB issues a measurement task to UE1 to measure the cells on f2 and f3;

[0070] In this example, if figure 2 and image 3 As shown, it is assumed that f1 and f2 belong to frequency band 1, f3 belongs to frequency band 3, the cell on f1 is Cell1, the cell on f2 is Cell2, and the cell on f3 is Cell3. The specific steps are described as follows:

[0071] Step 1: UE1 enters the connection state through Cell1 in the eNB;

[0072] Step 2: eNB initiates a capability query process to UE1, UE1 reports support for carrier aggregation of frequency band 1 and frequency band 1, carrier aggregation of frequency band 1 and frequency band 3, and supports MTA at the same time;

[0073] Step 3: UE1 moves into the coverage of RRH and repeater. Due to the increase of traffic, eNB decides to configure carrier aggregation;

[0074] Step 4: eNB issues a measurement task to UE1 to measure the cells on f2 and f3;

[0075] Step 5: UE1 performs measurement and reports a measurement report. Cell2 on f2 meets the reporting conditions and reports to eNB. Meanwhile, Cell3 on f
