Abstract: A method for receiving downlink control information by a terminal in a wireless communication system may include receiving control channel element (CCE) configuration information from a base station; determining multiple control channel candidates, each of which has one or more CCEs, on the basis of the CCE configuration information; and blind-detecting downlink control information through the multiple control channel candidates, wherein: each of the one or more CCEs includes multiple resource element groups (REGs), and the number of data resource elements (REs) for carrying the downlink control information is independently determined for each REG; and the CCE configuration information indicates whether each CCE has a fixed number of REGs or a fixed number of data REs. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: A method and apparatus for determining a control resource set for system information in a wireless communication system is provided. A user equipment (UE) receives a configuration of control resource set (CORESET) for remaining system information (RMSI) via a synchronization signal (SS) block from a network, and determines the control resource set for the RMSI according to the configuration. The SS block may include a physical broadcast channel (PBCH). A time and frequency location of a common search space (CSS) for the RMSI may be aligned with the SS block by at least one of time division multiplexing (TDM) or frequency division multiplexing (FDM).

Abstract: A user equipment, according to one embodiment of the present invention, monitors candidates of a control channel which schedules system information in a configured specific CORESET based on a PBCH signal, obtains the system information scheduled by the control channel, and obtain a only part of entire parameters for configuring the specific CORESET from the PBCH signal. In this case, the user equipment can monitor the candidates of the control channel by assuming that remaining parameters for configuring the specific CORESET not obtained through the PBCH signal are fixed as follows a size of 1 REG bundle is fixed to 6 REGs, a CCE-to-REG mapping type is fixed to interleaving, a row size of an interleaver for interleaving is fixed to 2, and a precoder granularity which is a unit of the same precoding assumption is fixed to 1 REG bundle.
