- CA Carrier Aggregation
- the CA technology means that multiple carriers with overlapping coverage areas in the physical space are grouped together under the same eNB, and one UE (user equipment) is served to provide the service rate required by the UE.
- Each carrier participating in the CA is called a CC (Component Carrier) of the UE.
- CC Component Carrier
- each cell under the eNB is defined and has only one carrier. Therefore, carrier aggregation can also be understood as the fact that one UE simultaneously uses
- FIG. 1 is a schematic diagram of a CA technology of LTE-A in the prior art.
- the eNB base station
- the eNB simultaneously performs data transmission with the UE on 4 CCs to improve system UE throughput.
- LTE-A and LTE UEs For both LTE-A and LTE UEs, they can see four LTE-A cells with the same coverage under the eNB.
- the LTE-A UE can schedule the resources of one or more cells to serve the UE according to the requirements of the user service rate.
- the network For the LTE UE, the network can only schedule the resources of one cell to serve the UE.
- FIG. 2 is a structural diagram of the downlink subframe.
- Each downlink subframe is composed of several OFDM symbols, and the first 0 to 3 OFDM of the downlink subframe (Orthogonal)
- the frequency division multiplexing (OFDM) symbol is a control symbol for carrying downlink control signaling, and the channel carrying downlink control signaling is called a PDCCH (Packet Data Control CHannel) channel.
- PDCCH Packet Data Control CHannel
- the remaining OFDM symbols carry the downlink data, and the physical layer channel carrying the downlink data is called a PDSCH (Physical Downlink Shared CHannel) channel.
- the control signaling may include: scheduling information about the current downlink subframe and the corresponding uplink subframe, and related HARQ (Hybrid Automatic Repeat reQuest) information.
- the UE determines whether resources are allocated in the corresponding subframe by receiving control signaling of the downlink subframe. If the resource is allocated, the UE obtains the time frequency location of the resource according to the indication of the scheduling signaling, and performs data transmission and reception.
- a disadvantage of the prior art is that since the CA technology is introduced in the LTE-A system, that is, the UE may configure multiple CCs at the same time, one LTE-A UE may simultaneously use multiple CCs for data transmission.

- the terminal UE simultaneously monitors the PDCCH and the PDSCH on multiple CCs.
- the amount of data of the terminal UE is not large, there is not much need to monitor multiple CCs at the same time. If the reception and decoding of unused CCs are stopped, the terminal will be saved.
- the UE has a large amount of data to be sent and received, the UE needs to enable monitoring of the corresponding CC carrier.
- the set of carriers that the UE needs to listen to is determined by the network. This requires that the UE be notified when the network decides to change the set of carriers that the LTE-A UE needs to listen to.

- the bitmap of the first byte corresponds to the CC of 0 ⁇ 6
- the bitmap of the second byte corresponds to the CC of 7 ⁇ 13, and so on. If a bit is set to 1 in the bitmap, the UE needs to activate the monitoring of the CC corresponding to the bit; otherwise, the UE should deactivate the monitoring of the CC corresponding to the bit.
- Step S602 The UE instructs the MAC CE to change the listening instruction according to the component carrier and the corresponding CC activates or deactivates the monitoring of the corresponding CC.
- the eNB also needs to update the listening record of the corresponding UE. Specifically, the eNB updates the CC listening record of the UE according to the transmitted component carrier MAC CE, to ensure that the UE and the network side consistently monitor the CC records monitored by the UE.
