AI Technical Summary
In the new air interface system, the physical downlink control channel (PDCCH) overhead of the primary cell (PCell) is relatively large, which increases the complexity of terminal equipment.
By configuring multiple search space sets, and discarding some or all of the PDCCH candidates when the number of PDCCH candidates in the first search space set exceeds the terminal's capacity, a second search space set is formed. Control information (DCI) is transmitted on this set, and cross-carrier scheduling is performed using secondary cells (SCells) to reduce the PDCCH overhead of PCells.
It effectively reduces the PDCCH overhead of PCell, solves the problem of limited PCell control channel capacity, and improves the processing capability of terminal equipment.
