Method and device for transmitting/receiving downlink control information in wireless communication system
摘要
說明書
Here, a UE may repeatedly receive DCI from a plurality of TRPs (or base stations/cells/panels) through a plurality of PDCCH candidates, and PDCCH candidates transmitted from different TRPs may be mapped to different TCI states.
Here, the same DCI may be transmitted through PDCCH candidate 1 and PDCCH candidate 2. In addition, as described above, PDCCH candidate 1 and PDCCH candidate 2 may be transmitted based on different TCI states, respectively. In this case, as in embodiment 1-1, PDCCH candidate 1 and PDCCH candidate 2 may share one (same) CORESET, but may be defined/configured in different SS sets. Alternatively, as in embodiment 1-2, PDCCH candidate 1 and PDCCH candidate 2 may be defined/configured in one (same) CORESET and one (same) SS set. Alternatively, as in embodiment 1-3, PDCCH candidate 1 and PDCCH candidate 2 may be defined/configured in different CORESETs and may be defined/configured in different SS sets. Alternatively, as in embodiment 1-4, PDCCH candidate 1 and PDCCH candidate 2 are defined/configured in different CORESETs, but may be defined/configured in one (same) SS set. For more detailed operation, reference may be made to the above description.
To describe an example of embodiment 1-1 in more detail, in step S1901, DCI may be transmitted through a first PDCCH candidate in a first search space set and a second PDCCH candidate in a second search space set. In addition, the first search space set and the second search space set may be associated with different TCI states. That is, the first PDCCH candidate and the second PDCCH candidate may be associated with different TCI states.
