The present disclosure relates to a communication technique for converging, with an IoT technology, a 5G communication system for supporting a higher data transfer rate than 4G systems, and a system therefor. The present disclosure may be applied to 5G communication technology and IoT related technology-based intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail, security and safety related services, etc.). The present invention relates to a scheduling method and apparatus for uplink data transmission and downlink data reception.
1. A method for communicating with a base station by a terminal in a wireless communication system, the method comprising:
receiving, from the base station, downlink control information (DCI) comprising scheduling information through a control resource set (CORESET);
determining a time resource set to which the scheduling information is to be applied between a first time resource table and a second time resource table, wherein one of the first time resource table or the second time resource table is selected based on a position of the CORESET in a slot; and
communicating with the base station according to time domain resource allocation information indicated by the scheduling information in the determined time resource set,
wherein the first time resource table and the second time resource table are separately configured,
wherein the first time resource table is selected in case that the position of the CORESET precedes a position of predetermined symbol, and
wherein the second time resource table is selected in case that the position of the CORESET follows the position of predetermined symbol.
2. The method of claim 1 , wherein 1 ,
the second time resource table has a timepoint coming after the first time resource table.
3. The method of claim 1 , wherein the position of the CORESET is determined by a first or last symbol of the CORESET, and
in the communicating with the base station, an uplink signal is transmitted to the base station through a physical uplink shared channel (PUSCH), or a downlink signal is received from the base station through a physical downlink shared channel (PDSCH).
4. A terminal configured to communicate with a base station in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to:
receive, from the base station, downlink control information (DCI) comprising scheduling information through a control resource set (CORESET),
determine a time resource set to which the scheduling information is to be applied between a first time resource table and a second time resource table, wherein one of the first time resource table or the second time resource table is selected based on a position of the CORESET in a slot, and
communicate with the base station according to time domain allocation information indicated by the scheduling information in the determined time resource set,
wherein the first time resource table and the second time resource table are separately configured,
wherein the first time resource table is selected in case that the position of the CORESET precedes a position of predetermined symbol, and
wherein the second time resource table is selected in case that the position of the CORESET follows the position of predetermined symbol.
5. The terminal of claim 4 , wherein,
the second time resource table has a timepoint coming after the first time resource table.
6. The terminal of claim 4 , wherein the position of the CORESET is determined by a first or last symbol of the CORESET, and
the controller is configured to transmit an uplink signal to the base station through a physical uplink shared channel (PUSCH) or receive a downlink signal from the base station through a physical downlink shared channel (PDSCH).
7. A method for communicating with a terminal by a base station in a wireless communication system, the method comprising:
transmitting, to the terminal, downlink control information (DCI) comprising scheduling information through a control resource set (CORESET); and
communicating with the terminal according to time domain resource allocation information indicated by the scheduling information,
wherein a time resource set to which the scheduling information is to be applied is determined between a first time resource table and a second time resource table, wherein one of the first time resource table or the second time resource table is selected based on a position of the CORESET in a slot,
wherein the first time resource table and the second time resource table are separately configured,
wherein the first time resource table is selected in case that the position of the CORESET precedes a position of predetermined symbol, and
wherein the second time resource table is selected in case that the position of the CORESET follows the position of predetermined symbol.
8. The method of claim 7 , wherein
the second time resource table has a timepoint coming after the first time resource table.
9. The method of claim 8 , wherein the position of the CORESET is determined by a first or last symbol of the CORESET, and
in the communicating with the terminal, an uplink signal is received from the terminal through a physical uplink shared channel (PUSCH), or a downlink signal is transmitted to the terminal through a physical downlink shared channel (PDSCH).
10. A base station configured to communicate with a terminal in a wireless communication system, the base station comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to:
transmit, to the terminal, downlink control information (DCI) comprising scheduling information through a control resource set (CORESET), and
communicate with the terminal according to time domain resource allocation information indicated by the scheduling information,
wherein a time resource set to which the scheduling information is to be applied is determined between a first time resource table and a second time resource table, wherein one of the first time resource table or the second time resource table is selected based on a position of the CORESET in a slot,
wherein the first time resource table and the second time resource table are separately configured,
wherein the first time resource table is selected in case that the position of the CORESET precedes a position of predetermined symbol, and
wherein the second time resource table is selected in case that the position of the CORESET follows the position of predetermined symbol.
11. The base station of claim 10 , wherein
the second time resource table has a timepoint coming after the first time resource table.
12. The base station of claim 11 , wherein the position of the CORESET is determined by a first or last symbol of the CORESET, and
