SCHEDULED CELL IDENTIFICATION FOR MULTI-CELL SCHEDULING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17883560 titled 'SCHEDULED CELL IDENTIFICATION FOR MULTI-CELL SCHEDULING
Simplified Explanation
Methods, systems, and devices for wireless communications are described in this patent application. The focus is on reducing the overhead of a downlink control information (DCI) by compressing or removing the carrier indication field (CIF). The patent introduces the concept of multi-cell downlink control information (MC-DCI), which allows a user equipment (UE) to receive scheduling information for multiple scheduled cells via a scheduling cell.
- The patent proposes compressing or removing the carrier indication field (CIF) to reduce the overhead of the DCI.
- Radio resource control signaling is used to indicate the DCI payload size, control channel elements (CCEs), and/or physical downlink control channel (PDCCH) candidates per scheduled cell or group of scheduled cells.
- If the DCI payload sizes, CCEs, and/or PDCCH candidates differ for the scheduled cells indicated in the radio resource control message, the UE can determine to which scheduled cell(s) a received DCI in a PDCCH monitoring occasion applies based on the payload size and/or CCEs of the PDCCH monitoring occasion without using a CIF.
Potential applications of this technology:
- Wireless communication systems and networks
- Mobile devices and smartphones
- Internet of Things (IoT) devices
- 5G and future generations of wireless networks
Problems solved by this technology:
- Reducing the overhead of downlink control information (DCI)
- Efficiently scheduling communications for multiple scheduled cells
- Optimizing radio resource allocation in wireless networks
Benefits of this technology:
- Improved efficiency and capacity in wireless communications
- Reduced overhead and signaling complexity
- Enhanced user experience with faster and more reliable data transmission
- Better utilization of radio resources in multi-cell environments
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a multi-cell downlink control information (MC-DCI) that via a scheduling cell may schedule communications for more than one scheduled cells. The overhead of a DCI (e.g., an MC-DCI) may be reduced by compressing or removing the carrier indication field (CIF). For example, radio resource control signaling may indicate, to a UE, a DCI payload size, control channel elements (CCE)s, and/or physical downlink control channel (PDCCH) candidates per scheduled cell or per group of scheduled cells. If the DCI payload sizes, CCEs, and/or PDCCH candidates are different for the scheduled cells indicated in the radio resource control message, the UE may determine to which scheduled cell(s) a DCI received in a PDCCH monitoring occasion applies based on the payload size and/or CCEs of the PDCCH monitoring occasion without using a CIF.
