Definitions
- LTE devices can inherit the traditional advantages of LTE devices for wireless communication through licensed carriers, such as mobility, security, quality of service, and at the same time.
- licensed carriers such as mobility, security, quality of service
- the advantage of handling multi-user scheduling can also achieve the purpose of network capacity offloading by using the unlicensed carrier, thereby reducing the load of the licensed carrier.
- LAA system uses unlicensed band resources, it is subject to local regulations for the use of unlicensed bands.
- Resource sharing on the unlicensed band means that the use of a specific spectrum only specifies the limits of the transmit power and out-of-band leakage to ensure that the basic coexistence requirements are met between multiple devices sharing the band, and the radio is not limited.
- Operators can use the unlicensed band resources to achieve the purpose of network capacity offloading, but need to comply with the regulatory requirements of the unlicensed band resources in different geographies and different spectrums. These requirements are usually designed to protect public systems such as radar, as well as to ensure that multiple systems do not cause harmful effects and fair coexistence with each other, including emission power limits, out-of-band leak indicators, indoor and outdoor use restrictions, and areas. There are also some additional coexistence strategies and so on.
