SRIT (Set of Radio Interface Technologies) Explained in Detail
SRIT stands for Set of Radio Interface Technologies. It plays a crucial role in the development and standardization of mobile communication technologies, particularly for 5G (Fifth Generation) networks.
Here's a breakdown of the technical aspects:
IMT-2020 and 3GPP:
- The International Telecommunication Union (ITU) defines a series of recommendations for mobile telecommunication systems, with IMT-2020 outlining the requirements for 5G technology.
- 3GPP (3rd Generation Partnership Project) is a collaborative body of telecommunication standards organizations responsible for developing specifications for mobile networks, including those that meet IMT-2020 requirements.
Two Types of SRIT Submissions:
3GPP submitted two proposals to ITU for IMT-2020 compliance:
- Single Radio Interface Technology (RIT):
- This submission focuses on a single radio interface technology, specifically NR (New Radio) defined by 3GPP. NR is the core technology for 5G, offering features like enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (URLLC), and massive machine-type communication (mMTC).
- Set of Radio Interface Technologies (SRIT):
- This submission encompasses NR (as the core technology) along with other complementary radio interface technologies that can be used in conjunction with NR to meet the diverse requirements of IMT-2020. These include:
- E-UTRA/LTE (Evolved UMTS Terrestrial Radio Access Network/Long Term Evolution): This established technology from 4G can be utilized for backward compatibility with existing devices and infrastructure, as well as for scenarios where NR might not be the most suitable option.
- NB-IoT (Narrowband Internet of Things): This technology caters to low-power, wide-area IoT applications with minimal data transfer needs.
- eMTC (enhanced Machine-Type Communication): This technology addresses the needs of industrial IoT applications requiring moderate data rates and reliable communication.
- NR-NR Dual Connectivity: This allows a UE to simultaneously connect to both NR and LTE networks, potentially leveraging the strengths of both technologies.
- This submission encompasses NR (as the core technology) along with other complementary radio interface technologies that can be used in conjunction with NR to meet the diverse requirements of IMT-2020. These include:
Benefits of SRIT:
- Flexibility and Scalability: SRIT offers greater flexibility and scalability for 5G networks. Operators can choose the most appropriate technology (NR or a combination from the SRIT) based on specific user needs and network conditions.
- Backward Compatibility: The inclusion of LTE within SRIT facilitates a smoother transition from 4G to 5G, ensuring existing devices can still function on the network.
- Diverse Use Cases: SRIT caters to a wider range of use cases by providing technologies suited for various data requirements and communication characteristics.
Additional Notes:
- The specific details of the technologies within SRIT, and their integration with NR, can be found in the relevant 3GPP specifications for 5G NR and related technologies.
- The inclusion of additional technologies within the SRIT concept might be a possibility for future advancements in mobile communication.
I hope this explanation clarifies the technical aspects of SRIT and its role in 5G network standardization.
