TECHNIQUES FOR CROSS-CARRIER SCHEDULING FROM A SECONDARY CELL TO A PRIMARY CELL - A simplified explanation of the abstract
This abstract first appeared for US patent application 17758489 titled 'TECHNIQUES FOR CROSS-CARRIER SCHEDULING FROM A SECONDARY CELL TO A PRIMARY CELL
Simplified Explanation
Methods, systems, and devices for wireless communications are described in this patent application. The innovation focuses on a user equipment (UE) that can monitor search spaces on both a primary cell and a secondary cell in a carrier aggregation configuration. The UE monitors these search spaces based on a shared search space monitoring configuration to identify the secondary cell as a scheduling cell and the primary cell as a scheduled cell. The UE then monitors control channel candidates of search spaces on both cells for downlink control information messages that schedule data transmissions with the primary cell. The cross-carrier scheduled communications can be configured according to a scheduling configuration, which may include scheduling constraints.
- User equipment (UE) can monitor search spaces on a primary cell and a secondary cell in a carrier aggregation configuration.
- The UE identifies the secondary cell as a scheduling cell and the primary cell as a scheduled cell.
- Control channel candidates of search spaces on both cells are monitored for downlink control information messages.
- The control information messages schedule data transmissions with the primary cell.
- Cross-carrier scheduled communications can be configured with scheduling constraints.
Potential Applications
This technology has potential applications in the field of wireless communications, particularly in carrier aggregation configurations. It can be utilized in various wireless communication systems and devices, such as smartphones, tablets, and other mobile devices. The innovation enables efficient monitoring and scheduling of data transmissions across multiple cells, improving overall network performance and user experience.
Problems Solved
The technology solves the problem of efficiently monitoring and scheduling data transmissions in carrier aggregation configurations. By identifying the primary and secondary cells and monitoring their respective search spaces, the UE can effectively receive control information messages and schedule data transmissions with the primary cell. This helps optimize network resources and improve data transmission efficiency.
Benefits
The benefits of this technology include:
- Improved network performance and efficiency in carrier aggregation configurations.
- Enhanced user experience with faster and more reliable data transmissions.
- Optimal utilization of network resources through efficient monitoring and scheduling.
- Compatibility with various wireless communication systems and devices.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to monitor search spaces on a primary cell and an secondary cell in a carrier aggregation configuration. The UE may monitor the search spaces for control information according to a shared search space monitoring configuration. Based on the shared search space monitoring configuration, the UE may identify that the secondary cell is a scheduling cell and the primary cell is a scheduled cell (e.g., cross-carrier scheduling). The UE may monitor control channel candidates of search spaces on the primary cell and on the secondary cell for downlink control information messages scheduling data transmissions with the primary cell. In some examples, the cross-carrier scheduled communications may be configured according to a scheduling configuration, which may include one or more scheduling constraints.
