CONTROL CHANNEL CARRIER SWITCHING FOR SUBSLOT-BASED CELLS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17947571 titled 'CONTROL CHANNEL CARRIER SWITCHING FOR SUBSLOT-BASED CELLS
Simplified Explanation
The patent application describes techniques for facilitating control channel carrier switching for a subslot-based cell. The method involves configuring two cells with physical uplink control channel (PUCCH) resources and configuring at least one of the cells for subslot-based hybrid automatic repeat request acknowledgment (HARQ-ACK) reporting. The method also includes receiving a physical downlink control channel (PDCCH) and selecting a target PUCCH cell based on target PUCCH cell switching information. The selected cell is used for transmitting a PUCCH with HARQ-ACK feedback for the PDCCH or a physical downlink shared channel (PDSCH) scheduled by the PDCCH.
- The method involves configuring two cells with PUCCH resources and selecting a target PUCCH cell for transmitting PUCCH with HARQ-ACK feedback.
- The selection of the target PUCCH cell is based on target PUCCH cell switching information.
- The method allows for subslot-based HARQ-ACK reporting and transmission of PUCCH in a subslot or slot on the target PUCCH cell.
Potential Applications
- This technology can be applied in cellular networks to improve control channel carrier switching for subslot-based cells.
- It can enhance the efficiency and reliability of communication between user equipment (UE) and base stations.
Problems Solved
- The technique solves the problem of control channel carrier switching for subslot-based cells in cellular networks.
- It addresses the challenge of selecting the appropriate PUCCH cell for transmitting PUCCH with HARQ-ACK feedback.
Benefits
- The method improves the control channel carrier switching process, leading to better performance and reliability in cellular networks.
- It allows for efficient subslot-based HARQ-ACK reporting, enhancing the overall communication efficiency between UE and base stations.
Original Abstract Submitted
Certain aspects of the present disclosure provide techniques for facilitating control channel carrier switching for subslot-based cell. A method that may be performed by a user equipment (UE) includes receiving signaling configuring a first cell with physical uplink control channel (PUCCH) resources, configuring a second cell with PUCCH resources, and configuring at least one of the first cell or the second cell for subslot-based hybrid automatic repeat request acknowledgment (HARQ-ACK) reporting, receiving a physical downlink control channel (PDCCH), selecting, based on target PUCCH cell switching information, the first cell or the second cell as a target PUCCH cell for transmitting a PUCCH with HARQ-ACK feedback for the PDCCH or a physical downlink shared channel (PDSCH) scheduled by the PDCCH, and transmitting the PUCCH with the HARQ-ACK feedback in a subslot or slot on the target PUCCH cell, in accordance with the selection.
