IDENTIFICATION OF CONTROL CHANNEL RESOURCE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17956557 titled 'IDENTIFICATION OF CONTROL CHANNEL RESOURCE
Simplified Explanation
The patent application relates to the transmission of physical uplink control channel (PUCCH) information. It describes a method for a user equipment to receive and identify a PUCCH resource for transmitting information associated with a physical downlink shared channel (PDSCH) transmission.
- The user equipment receives a first physical downlink control channel (PDCCH) candidate that carries a second PDCCH candidate, both associated with different aggregation levels.
- The user equipment identifies a PUCCH resource for transmitting information (e.g., ACK or NACK) related to a PDSCH transmission scheduled by the first PDCCH candidate.
- The PUCCH resource is identified based on a control channel element (CCE) index corresponding to the starting CCE of the first and second PDCCH candidates.
Potential Applications
- Wireless communication systems
- Mobile networks
- 5G and beyond technologies
Problems Solved
- Efficient transmission of PUCCH information
- Identification of PUCCH resource associated with a specific PDSCH transmission
- Handling multiple PDCCH candidates with different aggregation levels
Benefits
- Improved reliability and efficiency of PUCCH transmission
- Enhanced performance of wireless communication systems
- Optimal utilization of network resources
Original Abstract Submitted
Aspects relate to transmission of physical uplink control channel (PUCCH) information. A user equipment may receive a first physical downlink control channel (PDCCH) candidate carried by a control resource set that also carries a second PDCCH candidate, where these PDCCH candidates are associated with different aggregation levels. The user equipment may identify a PUCCH resource for transmission of information (e.g., an ACK or a NACK) that is associated with a physical downlink shared channel (PDSCH) transmission scheduled by the first PDCCH candidate. For example, the user equipment may identify the PUCCH resource based on a control channel element (CCE) index that corresponds to a starting CCE of the first PDCCH candidate and the second PDCCH candidate.
