As another example, when the first CORESET is configured according to an interleaving scheme, the second CORESET is configured according to a non-interleaving scheme, and the above-described overlapping region exists, the BS may transmit or receive a PDCCH to/from the terminal in each CORESET by using at least one method among the above-described method 2 and method 4.
Hereinabove, method 1 to method 5 have been separately described, but some of method 1 to method 5 may be combined and practiced.
Hereinabove, only an example in which two CORESETs overlap each other has been described, but the disclosure may also be similarly applied to an example in which multiple CORESETs overlap one another.
Embodiment 1-1 of the disclosure proposes a method for providing, by a BS, a terminal with notification of DMRS configuration information for a CORESET.
The BS may indicate DMRS configuration information (i.e., whether DMRS configuration is DMRS configuration #1 or DMRS configuration #2) for a CORESET, in which downlink control information (DCI) for scheduling of remaining system information (RMSI) can be transmitted, to the terminal via a master information block (MIB). In this example, RMSI may correspond to essential system information (SI), except for a MIB, which is transmitted on a physical broadcast channel (PBCH), and may correspond to, for example, SIB1 and SIB2 in LTE. Alternatively, DMRS configuration information for a CORESET, in which DCI for scheduling of RMSI can be transmitted, may be fixed to DMRS configuration #1.
