Abstract

A method of receiving, by a user equipment, a physical downlink shared channel (PDSCH) in a wireless communication system. The method includes receiving, from a base station (BS), a higher layer signal including first information for an uplink (UL)-downlink (DL) configuration; repeatedly receiving, from the BS, a first transport block (TB) via the PDSCH based on the first information for the UL-DL configuration; receiving, from the BS, a first control channel including second information for the UL-DL configuration; and discarding a second control channel based on: (i) the second control channel scheduling a PDSCH repetition of a second TB in a transmission time unit, (ii) the first information for the UL-DL configuration indicating the transmission time unit as an uplink, and (iii) the second information for the UL-DL configuration indicating the transmission time unit as a downlink.

Claims (30)

1. A method of receiving, by a user equipment, a physical downlink shared channel (PDSCH) in a wireless communication system, the method comprising:

receiving, from a base station (BS), a higher layer signal comprising first information for an uplink (UL)-downlink (DL) configuration;

repeatedly receiving, from the BS, a first transport block (TB) via the PDSCH based on the first information for the UL-DL configuration;

receiving, from the BS, a first control channel comprising second information for the UL-DL configuration; and

discarding a second control channel scheduling a PDSCH repetition of a second TB in a transmission time unit based on (i) the first information for the UL-DL configuration indicating the transmission time unit as an uplink, and (ii) the second information for the UL-DL configuration indicating the transmission time unit as a downlink.

2. The method of claim 1 , wherein the transmission time unit is a subframe or a special subframe.

3. The method of claim 1 , wherein the higher layer signal further comprises information for configuration of an enhanced interference mitigation and traffic adaptation (eIMTA) operation.

4. The method of claim 1 , wherein the first control channel is a physical downlink control channel (PDCCH) with a cyclic redundancy check (CRC) scrambled by an eIMTA-radio network temporary identifier (RNTI).

5. A user equipment (UE) configured to receive a physical downlink shared channel (PDSCH) in a wireless communication system, the UE comprising:

a transceiver;

at least one processor; and

at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:

receiving, from a base station (BS), a higher layer signal comprising first information for an uplink (UL)-downlink (DL) configuration;

repeatedly receiving, from the BS, a first transport block (TB) via the PDSCH based on the first information for the UL-DL configuration;

receiving, from the BS, a first control channel comprising second information for the UL-DL configuration; and

discarding a second control channel scheduling a PDSCH repetition of a second TB in a transmission time unit based on (i) the first information for the UL-DL configuration indicating the transmission time unit as an uplink, and (ii) the second information for the UL-DL configuration indicating the transmission time unit as a downlink.

6. The UE of claim 5 , wherein the transmission time unit is a subframe or a special subframe.

7. The UE of claim 5 , wherein the higher layer signal further comprises information for configuration of an enhanced interference mitigation and traffic adaptation (eIMTA) operation.

8. The UE of claim 5 , wherein the first control channel is a physical downlink control channel (PDCCH) with a cyclic redundancy check (CRC) scrambled by an eIMTA-radio network temporary identifier (RNTI).

9. A base station configured to transmit a physical downlink shared channel (PDSCH) in a wireless communication system, the base station comprising:

a transceiver;

at least one processor; and

at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:

transmitting, to a user equipment (UE), a higher layer signal comprising first information for an uplink (UL)-downlink (DL) configuration;

repeatedly transmitting, to the UE, a first transport block (TB) via the PDSCH; and

transmitting, to the UE, a first control channel comprising second information for the UL-DL configuration,

wherein a second control channel scheduling a PDSCH repetition of a second TB is discarded in a transmission time unit based on (i) the first information for the UL-DL configuration indicating the transmission time unit as an uplink, and (ii) the second information for the UL-DL configuration indicating the transmission time unit as a downlink.

10. The base station of claim 9 , wherein the transmission time unit is a subframe or a special subframe.

11. The base station of claim 9 , wherein the higher layer signal further comprises information for configuration of an enhanced interference mitigation and traffic adaptation (eIMTA) operation.

12. The base station of claim 9 , wherein the first control channel is a physical downlink control channel (PDCCH) with a cyclic redundancy check (CRC) scrambled by an eIMTA-radio network temporary identifier (RNTI).
