AI Technical Summary
In wireless communication systems, when using unlicensed frequency bands, existing technologies struggle to guarantee communication quality and avoid interference with existing wireless communication devices. This is especially true when using LTE and NR technologies in unlicensed frequency bands, where robust coexistence mechanisms need to be developed to ensure effective sharing and communication quality between devices.
By using a guard band on a carrier, the terminal receives information related to the resource area, receives indications of multiple resource sets from the base station, and receives downlink channels on designated resources. It communicates using the physical downlink control channel and the shared channel. The base station sends information related to the guard band to configure the resource set and ensure the effectiveness of channel transmission.
It enables efficient configuration of uplink and downlink channel resources in the presence of guard bands, improving channel transmission efficiency and communication quality, and reducing interference with existing equipment.
