Method and apparatus for transmitting and receiving wireless signal in wireless communication system
The present disclosure relates to a wireless communication system and, specifically, to a method and a device therefor, the method comprising the steps of: monitoring a plurality of PDCCH candidate sets within an SS set on a scheduling cell, to detect a PDCCH including scheduling information on at least one cell, wherein each PDCCH candidate set is associated with only one corresponding cell index, and if the at least one cell corresponds to a plurality of cells, PDCCH candidates for the PDCCH are configured in a PDCCH candidate set associated with a smallest cell index among cell indexes of the plurality of cells; and performing data communication on the at least one cell on the basis of the PDCCH.
1. A method of performing communication by a user equipment (UE) in a wireless communication system, the method comprising:
monitoring, by the UE, a plurality of physical downlink control channel (PDCCH) candidates;
decoding, by the UE, DCI (Downlink Control Information);
determining, by the UE, one or more scheduled cells based on the DCI; and
transmitting, by the UE, a PUSCH (Physical Uplink Shared Channel) in the one or more scheduled cells,
wherein the one or more scheduled cells are determined by a field in the DCI,
wherein a length of the field is based on a number of entries,
wherein the entries include combinations of scheduled cells for Uplink scheduling.
2. The method according to claim 1 , wherein the field is ceiling [log 2 (the number of entries)] bits.
3. A user equipment (UE) used in a wireless communication system, the UE comprising:
at least one radio frequency (RF) unit;
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor perform operations comprising:
monitoring a plurality of physical downlink control channel (PDCCH) candidates;
decoding DCI (Downlink Control Information);
determining one or more scheduled cells based on the DCI; and
transmitting a PUSCH (Physical Uplink Shared Channel) in the one or more scheduled cells,
wherein the one or more scheduled cells are determined by a field in the DCI,
wherein a length of the field is based on a number of entries,
wherein the entries include combinations of scheduled cells for Uplink scheduling.
4. The UE according to claim 3 , wherein the field is ceiling [log 2 (the number of entries)] bits.
5. A non-transitory computer-readable storage medium configured to store instructions that, when executed, cause at least one processor to perform operations comprising:
monitoring a plurality of physical downlink control channel (PDCCH) candidates;
decoding DCI (Downlink Control Information);
determining one or more scheduled cells based on the DCI; and
transmitting a PUSCH (Physical Uplink Shared Channel) in the one or more scheduled cells,
wherein the one or more scheduled cells are determined by a field in the DCI,
wherein a length of the field is based on a number of entries,
wherein the entries include combinations of scheduled cells for Uplink scheduling.
