Coexistence between LTE-MTC and NR
The present document is a technical report for the work item of R16 LTE-M [2]. The scope of the TR is as follows:
- For LTE-MTC in-band operation co-existence with NR, RAN4 will investigate the following:
- 15 kHz, 30 kHz, and 60 kHz numerologies for NR FR1 bands, with higher priority given first to 15 kHz and then to 30 kHz
- Study feasible LTE-MTC placement allocation without RF backward compatibility impact and compatible with Rel-13 LTE-MTC and Rel-15 NR, to operate simultaneously within various NR channel bandwidths
- Channel raster, PRB and subcarrier grid alignment between LTE-MTC and NR
- Synchronization issue between LTE-MTC and NR, including timing advance
- Frequency band support in LTE-MTC and NR
- Testability applicability
- Compatibility for Rel-15 NR and Rel-13/14/15 LTE-MTC
The case of NR configured with 15 kHz SS block SCS and the case of 30 kHz SS block SCS as specified in 38.101-1 are included in the study.The Rel-16 LTE-MTC and NR coexisting feature
