Unlicensed spectrum refers to radio frequency bands that are available for use without obtaining a specific license. These bands are shared among multiple users and technologies.
Carrier Aggregation:
In cellular networks, especially with 4G LTE and 5G NR, carrier aggregation is a technique where multiple frequency bands are aggregated to provide higher data rates and improved network performance.
NRU (NR Unlicensed):
If NRU has been introduced, it could refer to the use of unlicensed spectrum for NR (5G New Radio) communication. This might involve the aggregation of licensed and unlicensed spectrum bands to enhance data rates and network capacity.
Dynamic Spectrum Sharing:
Dynamic Spectrum Sharing (DSS) is a technology that allows the simultaneous usage of both 4G LTE and 5G NR in the same frequency band. It is possible that similar principles could be applied to unlicensed spectrum as well.
Licensed Assisted Access (LAA):
In 4G LTE, there's a technology called Licensed Assisted Access (LAA) that allows LTE to utilize unlicensed spectrum in conjunction with licensed bands. NRU could be a similar concept for 5G NR.
Regulatory Considerations:
The use of unlicensed spectrum is subject to regulatory considerations, and different regions may have different rules regarding its usage.
