DOWNLINK PRE-EMPTION AND UPLINK CANCELLATION FOR FULL-DUPLEX SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17879655 titled 'DOWNLINK PRE-EMPTION AND UPLINK CANCELLATION FOR FULL-DUPLEX SYSTEMS
Simplified Explanation
Methods, systems, and devices for wireless communication are described in this patent application. The patent application focuses on a specific aspect of wireless communication called sub-band full-duplex (SBFD) configuration.
- The user equipment (UE) receives an indication of the SBFD configuration of a cell serving the UE.
- The SBFD configuration includes a first set of resources for downlink communications and a second set of resources for uplink communications.
- The first set of resources and the second set of resources consist of non-overlapping frequency resources in the same time interval.
- The UE also receives a control message that indicates a pre-emption of the first set of resources or a cancellation of the second set of resources.
- Based on the control message and the SBFD configuration of the cell, the UE determines whether downlink transmissions in at least a portion of the first set of resources are pre-empted or whether uplink transmissions in at least a portion of the second set of resources are cancelled.
Potential Applications:
- This technology can be applied in various wireless communication systems, such as cellular networks, Wi-Fi networks, and other wireless communication networks.
- It can improve the efficiency and capacity of wireless communication by allowing simultaneous transmission and reception in different frequency resources.
Problems Solved:
- Traditional wireless communication systems often require separate frequency resources for uplink and downlink communications, which can limit the overall capacity and efficiency.
- This technology solves the problem of resource allocation by providing non-overlapping frequency resources for uplink and downlink communications in the same time interval.
Benefits:
- Enables simultaneous transmission and reception in different frequency resources, improving the overall capacity and efficiency of wireless communication.
- Enhances the flexibility of resource allocation, allowing for dynamic pre-emption or cancellation of specific frequency resources based on control messages.
- Supports various wireless communication systems, providing a versatile solution for improving wireless communication performance.
Original Abstract Submitted
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a sub-band full-duplex (SBFD) configuration of a cell serving the UE. The SBFD configuration may indicate a first set of resources for downlink communications and a second set of resources for uplink communications. The first set of resources and the second set of resources may include non-overlapping frequency resources in a same time interval. The UE may receive a control message that indicates a pre-emption of the first set of resources or a cancellation of the second set of resources. Accordingly, the UE may determine that downlink transmissions in at least a portion of the first set of resources are pre-empted or that uplink transmissions in at least a portion of the second set of resources are cancelled based on the control message and the SBFD configuration of the cell.
