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.

PDCCH DMRS scrambling initialization. When the field is absent the UE applies the value of the physCellld configured for this serving cell. precoderGranularity Precoder granularity in frequency domain rb-Offset Indicates the RB level offset in units of RB from the first RB of the first 6 RB group to the first RB of BWP. When the field is absent, the UE applies the value 0. reg-BundleSize Resource Element Groups (REGs) can be bundled to create REG bundles. This parameter defines the size of such bundles. shiftIndex When the field is absent the UE applies the value of the physCellIdconfigured for this serving cell. tci-PresentInDCI This field indicates if TCI field is present or absent in DCI format 1_1. When the field is absent, the UE considers the TCI to be absent/disabled. In case of cross carrier scheduling, the network sets this field to enabled for the ControlResourceSet used for cross carrier scheduling in the scheduling cell. tci-PresentInDCI-ForDCI-Format1-2 Configures the number of bits for “Transmission configuration indicator” in DCI format 1_2. When the field is absent the UE applies the value of 0 bit for the “Transmission configuration indicator” in DCI format 1_2. tci-StatesPDCCH-ToAddList
