Abstract
A method, which is performed by a terminal, for receiving a Physical Downlink Control Channel (PDCCH) in a wireless communication system comprises the steps of: receiving, from a base station, configuration information about a first control resource set (CORESET); receiving, from the base station, configuration information about a second CORESET; receiving, from the base station, a first PDCCH transmitted on the first CORESET; and receiving, from the base station, a second PDCCH transmitted on the second CORESET.
Claims20
A method for a terminal to perform wireless communication in a wireless communication system, the method comprising:
- receiving configuration information about a first control resource set (CORESET);
- receiving configuration information about a second CORESET;
- receiving configuration information about a first search space associated with the first CORESET;
- receiving configuration information about a second search space associated with the second CORESET;
- receiving a first PDCCH transmitted on the first search space;
- receiving a second PDCCH transmitted on the second search space,
- wherein first downlink control information (DCI) included in the first PDCCH and second DCI included in the second PDCCH are identical to each other;
- and
- transmitting a physical uplink control channel (PUCCH) on a resource determined based on an index of the first search space and an index of the second search space.
A terminal for performing wireless communication in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a processor configured to control the transceiver,
- wherein the processor is configured to:
- receive configuration information about a first control resource set (CORESET);
- receive configuration information about a second CORESET,
- receive configuration information about a first search space associated with the first CORESET,
- receive configuration information about a second search space associated with the second CORESET,
- receive a first PDCCH transmitted on the first search space,
- receive a second PDCCH transmitted on the second search space,
- wherein the first PDCCH and the second PDCCH are each repeatedly transmitted from the base station,
- wherein first downlink control information (DCI) included in the first PDCCH and second DCI included in the second PDCCH are identical to each other,
- transmit a physical uplink control channel (PUCCH) on a resource determined based on an index of the first search space and an index of the second search space.
