PRE-EMPTION, CONGESTION CONTROL, AND TX/RX ALIGNMENT FOR NR V2X UE WITH LIMITED POWER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17992413 titled 'PRE-EMPTION, CONGESTION CONTROL, AND TX/RX ALIGNMENT FOR NR V2X UE WITH LIMITED POWER
Simplified Explanation
The abstract describes a method and apparatus for pre-emption, congestion control, and Tx/Rx alignment for a partial sensing UE (User Equipment). The method involves measuring resources within a specific window, determining the number of measured resources with a certain signal strength, calculating a Channel Busy Ratio (CBR) based on the measured number of resources, and determining a Channel Reservation (CR) limit based on the CBR and transmission priority.
- The method measures resources within a specific window.
- It determines the number of measured resources with a signal strength above a certain threshold.
- It calculates a Channel Busy Ratio (CBR) based on the measured number of resources.
- It determines a Channel Reservation (CR) limit based on the CBR and transmission priority.
- The CBR is determined by comparing the total number of measured resources within the window to a second threshold.
- If the total number of measured resources is below the second threshold, a pre-configured CBR is used.
- If the total number of measured resources is equal to or above the second threshold, the CBR is calculated based on the ratio of resources with a signal strength above the threshold to the total number of measured resources.
Potential applications of this technology:
- Wireless communication systems
- Cellular networks
- Internet of Things (IoT) devices
- Smart devices and sensors
Problems solved by this technology:
- Pre-emption: The method allows for efficient pre-emption of resources by measuring their availability and determining the CBR and CR limit.
- Congestion control: By calculating the CBR based on the measured resources, the method helps in managing congestion in the network.
- Tx/Rx alignment: The method ensures proper alignment of transmission and reception by determining the CR limit based on the CBR and transmission priority.
Benefits of this technology:
- Improved resource allocation: The method helps in optimizing resource allocation by considering the measured resources and their signal strength.
- Efficient congestion control: By calculating the CBR, the method enables effective management of congestion in the network.
- Enhanced transmission and reception: The method ensures proper alignment of transmission and reception by determining the CR limit based on the CBR and transmission priority.
Original Abstract Submitted
A method and apparatus are provided for pre-emption, congestion control, and Tx/Rx alignment for use by a partial sensing UE. A method includes measuring resources within a first window; determining a number of the measured resources having an RSSI greater than a first threshold; determining a CBR based on the measured number of resources; and determining a CR limit based on the determined CBR and transmission priority. Determining the CBR based on the measured number of resources includes comparing a total number of measured resources within the first window to a second threshold; in response to the total number of measured resources being less than the second threshold, determining the CBR as a pre-configured CBR; and in response to the total number of measured resources being greater than or equal to the second threshold, determining the CBR based on a ratio of the number of the measured resources having the RSSI greater than the first threshold to the total number of measured resources within the first window.
