Design new standards for emerging technologies
By Vikram Singh
Different standardization bodies define the specification for different systems. One such standardization body is 3GPP which define protocols for 4G and 5G networks. The standards are designed separately for layer-1 (physical layer), layer-2 (MAC layer, radio link control layer, Service Data Adaptation Protocol (SDAP) layer and Packet Data Convergence Protocol (PDCP) layer) and layer-3 (RRC sublayer). The standards evolve over successive releases based on the objectives setup by 3GPP and prioritization by 3GPP-SA group. In every release of 3GPP, the stake holders considers the standards/protocols from previous release as the baseline and then enhance the signaling, air interface and procedure to meet the requirements. Finally based on the consensus amongst the companies, the agreements are taken as the precursor for other RAN working groups work.
In order to carry out This work, the participants are required with system-level simulators for following purposes:
- To first evaluate the performance of the network based on previous release signaling/protocols/procedures.
- These evaluations are considered as benchmarks for upcoming work.
- Design new methods to improve the performance of the network.
- Implement these methods and integrate then to the system level simulator for comparison with benchmarks.
- If new methods improves the performance, Identify signaling and protocol changes required to enable these methods.
These points demonstrate the importance of a system level simulator. It is crucial:
- For designing new algorithms which are compatible with practical networks.
- For identifying the enhancements requirements to enable a particular method/algorithm/technology for the network.
- For quantifying the amount of improvement offered by a particular method/algorithm/technology for various QoS.
