5G New Radio/LTE Sidelink Capacity Estimator
This 5G New Radio/LTE Sidelink Capacity Estimator computes the expected link capacity in data rate (Mbit/s) for sidelink considering 5G New Radio (NR) and Long Term Evolution (LTE) communication standards, as defined by The 3rd Generation Partnership Project (3GPP). Users can input the respective configuration parameters and evaluate the resulting capacity.
The tool provides side-by-side chart plotting between NR and LTE sidelink capacities for easy comparison. Data and generated charts can be exported to be used outside the tool.
In the current release, the tool applies to 10 MHz bands plus numerology 0 and 1 in case of 5G NR. One example is the public safety band, Band 14/n14 (the 700 MHz frequency band).
Uses
The tool can be used to estimate 5G NR and LTE sidleink capacity for 5G NR and LTE under different configurations. For 5G NR, the below configurations are supported:
- Numerology: 0 or 1 for the current release.
- Number of PRBs (Physical Resource Blocks): the allocated number of PRBs that is no larger than the maximum number of PRBs, which is 52 and 24 for numerology 0 and 1, respectively, per 3GPP for 10 MHz bands.
- Number of Layers: 1 or 2, per 3GPP for NR sidelink.
- UE (User Equipment) Max Modulation: 64QAM or 256QAM, per 3GPP and depending on the UE's capability.
- HARQ (Hybrid Automatic Repeat reQuest) Mode.
- Feedback-Based HARQ with Feedback Channel Period (slot) of 0, 1, 2, and 4 per 3GPP.
- Blind-Based HARQ with number of Blind Transmissions up to 32 per 3GPP.
For LTE, the below configurations are supported:
- The duration of the sidelink period: supported values are defined in 3GPP TS36.331.
- The duration of the physical sidelink channels within the period, i.e., Physical Sidelink Control Channel (PSCCH) and Physical Sidelink Shared Channel (PSSCH).
- The PSCCH time length: 2 – 40 Subframes per 3GPP TS36.213.
- The PSSCH time length: the remaining period duration after the preceding PSCCH.
- The selected Modulation and Coding Scheme (MCS) and number or PRBs for data transmission.
