Abstract

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The disclosure discloses a method performed by a user equipment (UE) in a wireless communication system and a UE performing the method. The method comprises receiving a downlink control information DCI format, wherein the DCI format is used for scheduling one or more uplink channels or downlink channels; and transmitting the one or more uplink channels or receiving the one or more downlink channels according to the DCI format.

Claims (36)

1 . A method performed by a user equipment (UE) in a wireless communication system, the method comprising:

receiving, from a base station, downlink control information (DCI) scheduling a plurality of physical downlink shared channels (PDSCHs) on a cell, wherein the DCI indicates a hybrid automatic repeat request (HARQ) process identifier (ID);

receiving, from the base station, PDSCHs among the plurality of PDSCHs scheduled by the DCI; and

transmitting, to the base station, HARQ-acknowledgement (HARQ-ACK) information associated with the PDSCHs by applying the HARQ process ID indicated by the DCI to one PDSCH of the PDSCHs and incrementing the HARQ process ID by 1 for each subsequent PDSCH of the PDSCHs, wherein the one PDSCH is a first PDSCH in time domain which does not overlap with an uplink symbol,

wherein a PDSCH which overlaps with the uplink symbol in the time domain is not received from the base station, and the HARQ process ID is not incremented for the PDSCH which overlaps with the uplink symbol.

2 . The method of claim 1 , wherein the HARQ-ACK information includes N bits for HARQ bundling.

3 . The method of claim 2 , wherein the N bits are identified based on a reception of a PDSCH not overlapping with the uplink symbol.

4 . The method of claim 1 , wherein the uplink symbol is indicated by a common time division duplex uplink and downlink configuration (tdd-UL-DL-ConfigurationCommon) or a dedicated time division duplex uplink and downlink configuration (tdd-UL-DL-ConfigurationDedicated) received from the base station.

5 . A method performed by a base station in a wireless communication system, the method comprising:

transmitting, to a user equipment (UE), downlink control information (DCI) scheduling a plurality of physical downlink shared channels (PDSCHs) on a cell, wherein the DCI indicates a hybrid automatic repeat request (HARQ) process identifier (ID); and

receiving, from the UE, HARQ-acknowledgement (HARQ-ACK) information associated with PDSCHs among the plurality of PDSCHs scheduled by the DCI, wherein the HARQ process ID indicated by the DCI is applied to one PDSCH of the PDSCHs and incremented by 1 for each subsequent PDSCH of the PDSCHs, and the one PDSCH is a first PDSCH in time domain which does not overlap with an uplink symbol,

wherein the HARQ process ID is not incremented for a PDSCH which overlaps with the uplink symbol.

6 . The method of claim 5 , wherein the HARQ-ACK information includes N bits for HARQ bundling.

7 . The method of claim 6 , wherein the N bits indicate a result of a reception of a PDSCH not overlapping with the uplink symbol.

8 . The method of claim 5 , wherein the uplink symbol is indicated by a common time division duplex uplink and downlink configuration (tdd-UL-DL-ConfigurationCommon) or a dedicated time division duplex uplink and downlink configuration (tdd-UL-DL-ConfigurationDedicated) transmitted to the UE.

9 . A user equipment (UE) comprising:

at least one transceiver;

at least one processor communicatively coupled to the at least one transceiver; and

at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the UE to:

receive, from a base station, downlink control information (DCI) scheduling a plurality of physical downlink shared channels (PDSCHs) on a cell, wherein the DCI indicates a hybrid automatic repeat request (HARQ) process identifier (ID),

receive, from the base station, PDSCHs among the plurality of PDSCHs scheduled by the DCI, and

transmit, to the base station, HARQ-acknowledgement (HARQ-ACK) information associated with the PDSCHs by applying the HARQ process ID indicated by the DCI to one PDSCH of the PDSCHs and incrementing the HARQ process ID by 1 for each subsequent PDSCH of the PDSCHs, wherein the one PDSCH is a first PDSCH in time domain which does not overlap with an uplink symbol,

10 . The UE of claim 9 , wherein the HARQ-ACK information includes N bits for HARQ bundling.

11 . The UE of claim 10 , wherein the N bits are identified based on a reception of a PDSCH not overlapping with the uplink symbol.

12 . The UE of claim 9 , wherein the uplink symbol is indicated by a common time division duplex uplink and downlink configuration (tdd-UL-DL-ConfigurationCommon) or a dedicated time division duplex uplink and downlink configuration (tdd-UL-DL-ConfigurationDedicated) received from the base station.

13 . A base station comprising:

at least one transceiver;

at least one processor communicatively coupled to the at least one transceiver; and

at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the base station to:

transmit, to a user equipment (UE), downlink control information (DCI) scheduling a plurality of physical downlink shared channels (PDSCHs) on a cell, wherein the DCI indicates a hybrid automatic repeat request (HARQ) process identifier (ID), and

receive, from the UE, HARQ-acknowledgement (HARQ-ACK) information associated with PDSCHs among the plurality of PDSCHs scheduled by the DCI, wherein the HARQ process ID indicated by the DCI is applied to one PDSCH of the PDSCHs and incremented by 1 for each subsequent PDSCH of the PDSCHs, and the one PDSCH is a first PDSCH in time domain which does not overlap with an uplink symbol,

wherein the HARQ process ID is not incremented for a PDSCH which overlaps with the uplink symbol.

14 . The base station of claim 13 , wherein the HARQ-ACK information includes N bits for HARQ bundling.

15 . The base station of claim 14 , wherein the N bits indicate a result of a reception of a PDSCH not overlapping with the uplink symbol.

16 . The base station of claim 13 , wherein the uplink symbol is indicated by a common time division duplex uplink and downlink configuration (tdd-UL-DL-ConfigurationCommon) or a dedicated time division duplex uplink and downlink configuration (tdd-UL-DL-ConfigurationDedicated) transmitted to the UE.
