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

A subset of the TCI states defined in pdsch-Config included in the BWP-DownlinkDedicated corresponding to the serving cell and to the DL BWP to which the ControlResourceSet belong to. They are used for providing QCL relationships between the DL RS(s) in one RS Set (TCI-State) and the PDCCH DMRS ports. The network configures at most maxNrofTCI-StatesPDCCH entries.

Table 8 illustrates information signaled for ControlResourceSet.

TABLE 8 For each CORESET, the UE is provided the following by ControlResourceSet: - a CORESET index p, by controlResourceSetId, where ?- 0 < p < 12 if coresetPoolIndex is not provided, or if a value of coresetPoolIndex is same for all CORESETs if coresetPoolIndex is provided; ?- 0 < p < 16 if coresetPoolIndex is not provided for a first CORESET, or is provided and has a value 0 for a first CORESET, and is provided and has a value 1 for a second CORESET; - a DM-RS scrambling sequence initialization value by pdcch- DMRS-ScramblinglD;
