The 38.211 application field and working principle is an important part of the 5G Standard, serving as the foundation for the communication of devices in the 5G network. This document outlines the application fields and the working principle of 38.211, by specifying the interfaces between various devices in the network, the physical layer services provided by this standard, along with the scheduling principles of the physical layer resources.

The application field of 38.211 can be mainly divided into two parts: the macro-model network and the mobile network. The 38.211 application field in the macro-model network contains mainly the access network for wide range of wireless settings, including macrocellular access, metro access, access to Local Area Networks (LAN) and wide area networks (WAN). In these settings, the 38.211 technology is responsible for the mobility management of terminals, base stations, as well as the broadcasting and the provision of services for various multimedia applications.

In the field of the mobile network, the 38.211 application field can include mobile networks such as GSM, GPRS, UMTS as well as the emerging 4G and 5G networks. In these settings,38.211 technology provides access and mobility management, schedulers for base station radio resource management, and radio access network (RAN) connection management. This technology has also begun to make headways in the areas of multimedia broadcasting, multimedia delivery, and access to WiMax networks.

As for the working principle of 38.211, its architecture mainly consist of two main facets: the physical layer services and scheduling principles. Regarding the physical layer services, 38.211 specifies the interfaces between the devices in the communication network, including the transmission, reception and medium access control related functions. It also outlines the frequency-hopping patterns, multiple-access scheme selection, media avoidance, modulation, coding distribution, and the power control procedures of these physical layer resources.

The other aspect of its working principle is the scheduling principles of different physical layer resources. This involves addressing various factors such as channel attenuation, frequencies, contention lookups, and air-link duration. The scheduling principles also serves as a round robin mechanism that determines the order between different physical layer resources in the communication. This will enable the effective utilization of the physical layer resources according to pre-defined technical control plans and rules and prevent any potential congestion or interference.

In conclusion, the 38.211 application field and working principle is an important part of the 5G Standard. It enables the communication of devices in the 5G network, providing access network coverage and radio access network management, as well as the physical layer services and scheduling principles. These technologies will play an essential role in the development of 5G network and its emerging services.
