METHODS FOR DCI CONFIGURATIONS AND PROCEDURES WITH MULTI-CELL SCHEDULING DCI - A simplified explanation of the abstract
This abstract first appeared for US patent application 18116168 titled 'METHODS FOR DCI CONFIGURATIONS AND PROCEDURES WITH MULTI-CELL SCHEDULING DCI
Simplified Explanation
- The patent application describes different approaches to scheduling data transmission in a wireless communication system. - One approach involves configuring only one component carrier with multi-cell scheduling control information, while the other component carriers have no control information configured. - Another approach configures all component carriers with multi-cell scheduling control information. - A third option configures one component carrier with multi-cell scheduling control information and the others with legacy single-cell scheduling control information. - A fourth option configures one component carrier with both multi-cell and single-cell scheduling control information, while the others have only single-cell scheduling control information. - A fifth option configures all component carriers with both multi-cell and single-cell scheduling control information. - The patent application also describes dropping rules for situations where there are more scheduling candidates than the user equipment can handle. - The dropping rules may prioritize candidates with multi-cell scheduling control information. - The impact on control information formats to accommodate both single-cell and multi-cell scheduling is also discussed. - The patent application also sets limits on the number and sizes of the control information.
Original Abstract Submitted
Described are approaches to multi-cell PUSCH/PDSCH scheduling with a single DCI (downlink control information) in a wireless communication system. In one approach, only one component carrier is configured with the multi-cell scheduling DCIs, with no DCI configured on the other component carriers. In a second approach, all of the component carriers can be configured with the multi-cell scheduling DCIs. In a third option, one component carrier is configured with multi-cell scheduling DCI only, while the other component carriers can be configured with the legacy single-cell scheduling DCIs. In a fourth option, one component carrier is configured with both multi-cell scheduling DCIs and the legacy single-cell scheduling DCIs, while the other component carriers can be configured with the legacy single-cell scheduling DCIs. In the fifth option, all the component carriers can be configured with both multi-cell scheduling DCIs and the legacy single-cell scheduling DCIs. In addition, dropping rules are described for the situations of overbooking, i.e., when the number of PDCCH candidates exceeds the capabilities of the user equipment (UE). Potential dropping rules include following the legacy procedure, and providing higher priority to candidates with user-specific search spaces with multi-cell scheduling DCIs. Also described is the impact on DCI formats to accommodate single-cell and multi-cell scheduling DCIs on the same component carrier. Finally, limits on the number and sizes of the DCIs are described.
