FLEXIBLE RESOURCE ALLOCATION FOR NARROWBAND AND WIDEBAND COEXISTENCE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240195546 titled 'FLEXIBLE RESOURCE ALLOCATION FOR NARROWBAND AND WIDEBAND COEXISTENCE
Abstract: A user equipment (UE) (e.g., an enhanced machine type communication (eMTC) UE) may identify several narrowbands associated with eMTC protocol based on a system bandwidth of a new radio (NR) carrier. A base station may transmit an indication of a set of valid narrowbands for eMTC (e.g., based on coexistence considerations between eMTC and NR) to the UE. The base station may further transmit a frequency hopping pattern to the UE (e.g., associated with narrowbands within the set of valid narrowbands), and transmit one or more downlink transmissions according to the frequency hopping pattern. Additionally or alternatively, a base station may identify a subcarrier offset and/or resource block offset between resources (e.g., a resource grid) used for eMTC protocol and resources used for NR. The base station may transmit a frequency alignment parameter to the UE, and the UE may align narrowbands for eMTC accordingly.
Key Features and Innovation:
- UE identifies narrowbands for eMTC protocol based on NR carrier bandwidth.
- Base station transmits valid narrowbands and frequency hopping pattern to UE.
- Base station provides frequency alignment parameter for UE to align narrowbands.
Potential Applications: This technology can be applied in IoT devices, smart meters, and other eMTC-enabled devices that require efficient communication within a NR carrier bandwidth.
Problems Solved: This technology addresses the challenge of efficiently utilizing narrowbands for eMTC protocol within the spectrum allocated for NR carriers.
Benefits:
- Improved coexistence between eMTC and NR protocols.
- Enhanced communication efficiency for eMTC-enabled devices.
- Optimal allocation of resources for eMTC within NR carrier bandwidth.
Commercial Applications: This technology can be utilized in smart city infrastructure, industrial IoT applications, and remote monitoring systems to enhance communication reliability and efficiency.
Prior Art: Prior research in the field of spectrum allocation and resource management for IoT devices may provide insights into similar approaches to optimizing narrowband usage within a specific carrier bandwidth.
Frequently Updated Research: Ongoing research in spectrum sharing technologies and resource allocation for IoT devices may offer further advancements in optimizing communication protocols within limited bandwidth.
Questions about the Technology: 1. How does this technology improve the efficiency of communication for eMTC-enabled devices within a NR carrier bandwidth? 2. What are the potential implications of using frequency hopping patterns to optimize narrowband usage in eMTC protocols?
Original Abstract Submitted
a user equipment (ue) (e.g., an enhanced machine type communication (emtc) ue) may identify several narrowbands associated with emtc protocol based on a system bandwidth of a new radio (nr) carrier. a base station may transmit an indication of a set of valid narrowbands for emtc (e.g., based on coexistence considerations between emtc and nr) to the ue. the base station may further transmit a frequency hopping pattern to the ue (e.g., associated with narrowbands within the set of valid narrowbands), and transmit one or more downlink transmissions according to the frequency hopping pattern. additionally or alternatively, a base station may identify a subcarrier offset and/or resource block offset between resources (e.g., a resource grid) used for emtc protocol and resources used for nr. the base station may transmit a frequency alignment parameter to the ue, and the ue may align narrowbands for emtc accordingly.
