FEEDBACK CODEBOOK CONSTRUCTION FOR CONTROL CHANNEL CARRIER SWITCHING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17885208 titled 'FEEDBACK CODEBOOK CONSTRUCTION FOR CONTROL CHANNEL CARRIER SWITCHING
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications, specifically focusing on feedback messages generated by user equipment (UE) according to a feedback codebook and scheme for physical downlink shared channels (PDSCHs) prior to a bandwidth part (BWP) switch.
- User equipment (UE) determines whether to include or exclude feedback information for PDSCHs occurring before a BWP switch.
- UE decides whether to include feedback information for PDSCHs before an uplink BWP switch based on cell switching support, the cell of the uplink BWP switch, the cell of scheduled feedback transmission, and the mode of PUCCH cell switching.
- UE also determines whether to send retransmissions of feedback information after a BWP switch.
- Potential Applications
- 5G and future wireless communication systems
- Mobile devices and networks
- Internet of Things (IoT) devices
- Problems Solved
- Efficient handling of feedback information in wireless communication systems
- Seamless switching between cells in a network
- Optimizing resource allocation for PDSCHs and feedback transmissions
- Benefits
- Improved reliability and performance in wireless communications
- Enhanced user experience with faster and more efficient data transmission
- Better utilization of network resources for increased capacity and coverage.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may generate feedback messages according to a feedback codebook according to a feedback scheme indicating whether the UE is to include, or exclude, feedback information for physical downlink shared channels (PDSCHs) occurring prior to a bandwidth part (BWP) switch. For example, the UE may determine whether to include feedback information for any PDSCHs that occur prior to an uplink BWP switch for a UE that supports cell switching based on the cell in which the uplink BWP switch occurs, the cell in which the feedback message is scheduled for transmission (e.g., the same cell in which the PDSCHs occur, or a different cell), and a mode of PUCCH cell switching (e.g., dynamic or semi-static). The UE may also determine whether to send retransmissions of feedback information after a BWP switch.
