Method and device for transmitting/receiving downlink control information in wireless communication system

說明書
Alternatively, DCI 1 and DCI 2 may be DCI parts in which one DCI is divided as in embodiment 2 above. In addition, DCI 1 may be transmitted through PDCCH candidate 1, DCI 2 may be transmitted through PDCCH candidate 2, and PDCCH candidate 1 and PDCCH candidate 2 may be aggregated to form a single PDCCH candidate in which one DCI is transmitted. In addition, PDCCH candidate 1 and PDCCH candidate 2 may be transmitted based on different TCI states, respectively. In this case, as in embodiment 2-1 above, one PDCCH candidate dividedly transmitted from a plurality of TRPs may be defined/configured in one (same) CORESET, but may be defined/configured in different SS sets. Alternatively, as in embodiment 2-2 above, one PDCCH candidate dividedly transmitted from a plurality of TRPs may be defined/configured in one (same) CORESET and one (same) SS set. Alternatively, as in embodiment 2-3 above, one PDCCH candidate dividedly transmitted from a plurality of TRPs may be defined/configured in a plurality of CORESETs and may be defined/configured in a plurality of SS sets. Alternatively, as in embodiment 2-4 above, one PDCCH candidate dividedly transmitted from a plurality of TRPs is defined/configured in a plurality of CORESETs, but may be defined/configured in one SS set. For more detailed operation, reference may be made to the description of the embodiment above.
In addition, for example, as in the above-described embodiment 3, the above-described MTRP PDCCH transmission method may be determined based on configuration of CORESET and SS configured to a UE. For example, the MTRP PDCCH transmission method (scheme) may be configured based on a combination of the configured number of CORESETs and the number of SSs and/or configuration of parameters related to each CORESET/SS.
