System and method for a user equipment to process overlapping physical downlink shared channels

1 . A method, comprising:

receiving a first physical downlink shared channel (PDSCH);

receiving a second PDSCH that overlaps in time with the first PDSCH;

determining a delay in processing time for a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) corresponding to the second PDSCH based on the overlapping time between the first PDSCH and the second PDSCH;

determining a symbol to initiate transmitting the HARQ-ACK corresponding to the second PDSCH based on the determined delay in processing time; and

transmitting, starting at the determined symbol, the HARQ-ACK corresponding to the second PDSCH.

2 . The method of claim 1 , wherein the delay in processing time is determined based on a fixed value of delay between a user equipment (UE) and a terminal.

3 . The method of claim 1 , wherein the delay in processing time is determined based on a user equipment (UE) capability.

4 . The method of claim 3 , wherein the delay in processing time is determined to be between a UE capability value indicating a minimum delay supported by the UE and a maximum processing time relaxation amount allowed by a network.

5 . The method of claim 1 , wherein the delay in processing time is determined based on a code block (CB) user equipment (UE) processing time.

6 . The method of claim 5 , wherein the delay in processing time is further determined based on a CB processing time of the first PDSCH.

7 . The method of claim 6 , wherein the delay in processing time is further determined based on a maximum overall CB of the first PDSCH.

8 . A user equipment (UE), comprising:

a transceiver; and

a processor configured to:

receive, from a terminal, a first physical downlink shared channel (PDSCH);

receive, from the terminal, a second PDSCH that overlaps in time with the first PDSCH;

determine a delay in processing time for a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) corresponding to the second PDSCH based on the overlapping time between the first PDSCH and the second PDSCH;

determine a symbol to initiate transmitting the HARQ-ACK corresponding to the second PDSCH based on the determined delay in processing time; and

transmit, to the terminal, starting at the determined symbol, the HARQ-ACK corresponding to the second PDSCH.

9 . The UE of claim 8 , wherein the processor is further configured to determine the delay in processing time based on a fixed value of delay between the UE and the terminal.

10 . The UE of claim 8 , wherein the processor is further configured to determine the delay in processing time based on a UE capability.

11 . The UE of claim 10 , wherein the processor is further configured to determine the delay in processing time to be between a UE capability value indicating a minimum delay supported by the UE and a maximum processing time relaxation amount allowed by a network.

12 . The UE of claim 8 , wherein the processor is further configured to determine the delay in processing time based on a code block (CB) UE processing time.

13 . The UE of claim 12 , wherein the processor is further configured to determine the delay in processing time based on a CB processing time of the first PDSCH.

14 . The UE of claim 13 , wherein the processor is further configured to determine the delay in processing time based on a maximum overall CB of the first PDSCH.

15 . A terminal, comprising:

a transceiver; and

a controller configured to:

transmit, to a user equipment (UE), a first physical downlink shared channel (PDSCH);

transmit, to the UE, a second PDSCH that overlaps in time with the first PDSCH;

receive, from the UE, a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) corresponding to the second PDSCH,

wherein the HARQ-ACK corresponding to the second PDSCH is received starting in a symbol determined in according with a delay in processing time that is delayed determined by the UE based on the overlapping time between the first PDSCH and the second PDSCH.

16 . The terminal of claim 15 , wherein the HARQ-ACK is delayed by the UE based on a fixed value of delay between the UE and the terminal.

17 . The terminal of claim 15 , wherein the HARQ-ACK is delayed by the UE based on a UE capability.

18 . The terminal of claim 17 , wherein the delay of the HARQ-ACK is determined by the UE to be between a UE capability value indicating a minimum delay supported by the UE and a maximum processing time relaxation amount allowed by a network.

19 . The terminal of claim 15 , wherein the HARQ-ACK is delayed by the UE based on a code block (CB) UE processing time.

20 . The terminal of claim 19 , wherein HARQ-ACK is delayed by the UE based on a CB processing time of the first PDSCH.
