MIMO Enhancement Through CORESET Pools for Out-of-Order Delivery

The patent segments the control resource set into multiple pools (first CORESET pool and second CORESET pool), each with independent timing relationships. This allows different segments (CORESET pools) to have different timing constraints, enabling out-of-order delivery while maintaining reliability within each segment. The UE can determine timing relationships based on which CORESET pool the DCI is received in, thus resolving the contradiction between strict timing and flexible delivery order.

The patent introduces CORESET pool index as an intermediary parameter that mediates between multiple DCIs with different timing relationships. The UE uses the CORESET pool index associated with each DCI to determine the appropriate timing relationship for PDSCH, PUSCH, and ACK/NACK. This intermediary mechanism simplifies the complexity by providing a clear mapping rule rather than requiring complex arbitration logic for multiple timing relationships.

The patent applies preliminary action by pre-configuring multiple CORESET pools with predetermined timing relationships before actual data transmission. The UE is provided with configuration information that includes the association between CORESET pool indices and timing relationships. When out-of-order delivery occurs, the UE can directly apply the pre-determined timing relationship based on the CORESET pool index, avoiding complex real-time timing calculations and thus improving productivity while maintaining timing synchronization.
