REFERENCE RESOURCE FOR DOWNLINK PREEMPTION IN NR-U - A simplified explanation of the abstract
This abstract first appeared for US patent application 17914536 titled 'REFERENCE RESOURCE FOR DOWNLINK PREEMPTION IN NR-U
Simplified Explanation
The abstract describes a method used by a network node in a wireless communication network to improve downlink transmission to multiple wireless devices. Here are the key points:
- The network node buffers data for downlink transmission to a first wireless device.
- The first data is preemptively transmitted on a channel that is subject to clear channel assessment procedures.
- The first data is transmitted in a specific domain within the channel, known as the reference downlink resource (RDR) domain.
- This RDR domain is the same channel where second data for a second wireless device was previously scheduled for transmission by the network node.
- A preemption indicator is also transmitted to the second wireless device, informing it about the RDR domain being used.
Potential applications of this technology:
- Wireless communication networks where multiple devices need to be served simultaneously.
- Networks with limited channel capacity that require efficient transmission methods.
- Environments where preemptive transmission can improve overall network performance.
Problems solved by this technology:
- Efficient utilization of available channel capacity by preemptively transmitting data in a specific domain.
- Minimizing delays and improving throughput for multiple wireless devices.
- Avoiding collisions and interference between simultaneous downlink transmissions.
Benefits of this technology:
- Improved downlink transmission efficiency and overall network performance.
- Reduced delays and improved throughput for wireless devices.
- Enhanced utilization of available channel capacity.
- Minimized collisions and interference between simultaneous transmissions.
Original Abstract Submitted
A method by a network node in a wireless communication network includes buffering first data for downlink transmission to a first wireless device, and preemptively transmitting the first data on a channel that is subject to clear channel assessment procedures. The first data is transmitted in a reference downlink resource (RDR) domain in the channel in which second data for a second wireless device was previously scheduled for transmission by the network node. The method further includes transmitting a preemption indicator to the second wireless device, the preemption indicator identifying the RDR domain. Related network nodes, methods of operating a wireless device, and wireless devices are also disclosed.
