eRedCap Carrier Coexistence
Resource Block Multiplexing on Commercial 5G Carriers
Radio resource management mechanisms ensuring thousands of 5 MHz eRedCap devices share wideband 100 MHz carriers without degrading smartphone speeds.
Technical Explanation
Deploying dedicated spectrum for IoT is economically unviable for cellular operators. 3GPP Rel-18 ensures eRedCap devices multiplex dynamically alongside full-capability smartphones inside standard 40/80/100 MHz carriers using dedicated Bandwidth Parts and puncturing techniques, ensuring zero loss in overall network capacity.
Key Functions
- Multiplexes narrowband IoT devices seamlessly across wideband 100 MHz carriers
- Prevents IoT traffic from degrading throughput for high-speed smartphone users
- Eliminates the requirement for dedicated or fragmented carrier spectrum allocations
- Optimizes common physical channel resources across heterogeneous device populations
Specifications
3GPP TS 38.300, TS 38.211 (Rel-18)
Interfaces
Uu (Bandwidth Part)
