摘要

Disclosed are a method and a device for transmitting or receiving downlink control information in a wireless communication system. A method for receiving downlink control information (DCI) according to an embodiment of the present disclosure any comprise the steps of: repeatedly receiving the DCI via a plurality of physical downlink control channel (PDCCH) candidates; and transmitting or receiving data scheduled via the DCI. The DCI may be transmitted via a first physical downlink control channel (PDCCH) candidate within a first search space set and a second PDCCH candidate within a second search space set, the first search space set and the second search space set may be related to different transmission configuration indication (TCI) states, and a window that is a duration in which the first PDCCH candidate and the second PDCCH candidate are transmitted may be preconfigured in a time domain.

說明書

Referring to FIG. 10, each PDCCH candidate may share the same CORESET and the same SS set, and FDM may be applied to PDCCH candidates 1 and 2. Both PDCCH candidates 1 and 2 may be defined/configured in one SS set and one CORESET mapped to the SS set. In this case, one of the two TCI states defined/configured in the CORESET may be used for some PDCCH candidates, and the remaining TCI state may be used for the remaining PDCCH candidates. For this, the mapping method between PDCCH candidates to TCIs may be referred to above.

For example, when there are 4 PDCCH candidates of aggregation level=4, TCI state 1 is mapped to the 1st and 3rd candidates, and TCI state 2 is mapped to the 2nd and 4th candidates, so that the TCI state may be mapped alternately. Here, PDCCH candidate 1 may exist among the first and third candidates, and PDCCH candidate 2 may exist among the second and fourth candidates. Alternatively, TCI state 1 is mapped to the 1st and 2nd candidates, and TCI state 2 is mapped to the 3rd and 4th candidates, so that the candidates of the previous half and the candidates of the following half may be mapped to different TCI states. Here, PDCCH candidate 1 may exist among the first and second candidates, and PDCCH candidate 2 may exist among the third and fourth candidates.

Extending the above example, similarly, for N TCI states, the N TCI states may be mapped one by one as the candidate index increases in a circular manner. Alternatively, all candidates may be divided into N groups by adjacent candidates (adjacent candidate indexes), and N candidate groups and N TCI states may be mapped 1:1.
