METHOD AND APPARATUS FOR LTE/NR SL CO-EXISTENCE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240114491 titled 'METHOD AND APPARATUS FOR LTE/NR SL CO-EXISTENCE
Simplified Explanation
The patent application describes a user equipment (UE) that can operate on both LTE and NR interfaces simultaneously, with different sub-carrier spacings. The UE is able to sense LTE transmissions, identify LTE subframes, and select NR resources for communication in overlapping NR slots.
- Transceiver configured for LTE and NR interfaces with different sub-carrier spacings
- Processor for sensing LTE transmissions and selecting NR resources
- LTE subframe overlapping with NR slots
- Sensing involves decoding control information and measuring receive power
- Transceiver transmitting in NR slots
Potential Applications
The technology can be applied in multi-connectivity scenarios where devices need to communicate over LTE and NR networks simultaneously.
Problems Solved
The technology solves the problem of efficiently utilizing LTE and NR resources in coexistence scenarios, ensuring seamless communication for the UE.
Benefits
The benefits of this technology include improved network efficiency, enhanced data rates, and better overall user experience in dual-connectivity environments.
Potential Commercial Applications
The technology can be utilized in 5G devices, IoT applications, smart cities, and other industries where seamless connectivity between LTE and NR networks is essential.
Possible Prior Art
One possible prior art could be the use of carrier aggregation in LTE networks to combine multiple carriers for increased data rates and improved performance.
Unanswered Questions
How does the UE handle interference between LTE and NR transmissions?
The UE may employ interference mitigation techniques such as power control, frequency hopping, or beamforming to minimize interference between LTE and NR transmissions.
What impact does the different sub-carrier spacings have on the overall system performance?
The larger sub-carrier spacing in the NR interface may lead to increased spectral efficiency but could also introduce challenges in resource allocation and interference management.
Original Abstract Submitted
a ue includes a transceiver configured to receive and transmit on a lte sl interface with a first sub carrier spacing (scs), and receive and transmit on a nr sl interface with a second scs larger than the first scs. a lte sl subframe overlaps in time with n nr sl slots. the ue further includes a processor operably coupled to the transceiver. the processor is configured to perform sensing over the lte sl interface, identify a presence of a lte sl transmission in a first lte sl sub-frame, and identify candidate nr sl resources for nr sl resource selection or reselection in n nr sl slots overlapping the first lte sl sub-frame. to perform the sensing, the processor is further configured to decode sl control information, and measure an sl reference signal receive power associated with the sci. the transceiver is further configured to transmit in the n nr sl slots.
