RATE MATCHING FOR UNLICENSED SIDELINK CHANNEL ACCESS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17840157 titled 'RATE MATCHING FOR UNLICENSED SIDELINK CHANNEL ACCESS
Simplified Explanation
Methods, systems, and devices for wireless communications are described in this patent application. The innovation focuses on improving sidelink communication in wireless networks. Here are the key points:
- The transmitting user equipment (UE) receives control information indicating a set of potential starting symbols for transmitting sidelink communication.
- The set of starting symbols includes a default starting symbol and one or more subsequent starting symbols.
- The transmitting UE performs a listen-before-talk procedure during the first slot to assess the channel's availability.
- Based on the listen-before-talk procedure's results, the transmitting UE selects a starting symbol from the set and initiates the sidelink communication.
- The selected starting symbol represents the beginning of a channel occupancy duration.
Potential applications of this technology:
- Enhancing communication between devices in wireless networks.
- Facilitating reliable and efficient sidelink communication in various scenarios, such as vehicle-to-vehicle communication, Internet of Things (IoT) devices, and proximity-based services.
- Enabling seamless and uninterrupted communication between devices in crowded wireless environments.
Problems solved by this technology:
- Mitigating interference and collisions in sidelink communication by performing a listen-before-talk procedure.
- Optimizing the selection of starting symbols to ensure efficient use of the wireless channel.
- Improving the reliability and performance of sidelink communication in wireless networks.
Benefits of this technology:
- Increased reliability and efficiency in sidelink communication.
- Enhanced overall performance of wireless networks by reducing interference and collisions.
- Improved user experience in scenarios where sidelink communication is crucial, such as vehicle-to-vehicle communication and IoT applications.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A transmitting user equipment may receive control information indicative of a plurality of starting symbols in a first slot, the plurality of starting symbols including at least one default starting symbol and one or more subsequent starting symbols, each of the plurality of starting symbols representing a potential starting symbol for transmission, by the transmitting UE, of a sidelink communication. The transmitting UE may perform a listen-before-talk procedure during at least the first slot and may transmit, to a receiving UE and based on performance of the listen-before-talk procedure during at least the first slot, at least an initial portion of the sidelink communication during a selected starting symbols of the plurality of starting symbols, the selected starting symbol being one of the one or more subsequent starting symbols and representing a beginning of a channel occupancy duration.
