Therefore, it is recommended that the radio frequency (RF) bandwidth of the terminal device can be adjusted according to the actual throughput of the terminal device. For this reason, the concept of Bandwidth Part (BWP) is introduced, and the motivation of BWP is to optimize the power consumption of terminal devices.

Since both asymmetric carrier aggregation and symmetric carrier aggregation are supported, the carriers required to be aggregated must have downlink carriers, but may not have uplink carriers. Moreover, for the primary carrier cell, there must be a physical downlink control channel (PDCCH) and PUCCH of the cell, and only the primary carrier cell has a PUCCH, and other secondary carrier cells may have a PDCCH.
- PDCH physical downlink control channel
