Abstract

Claims (55)

1. An apparatus comprising:

a processor;

memory coupled with the processor, and

instructions stored in the memory and executable by the processor to cause the apparatus to:

receive a downlink channel transmission carrying a downlink control information format that schedules a first uplink channel transmission;

determine an overlap between the first uplink channel transmission and a second uplink channel transmission, wherein the first uplink channel transmission is associated with a first priority, wherein the second uplink channel transmission is associated with a second priority different than the first priority; and

cancel the second uplink channel transmission before a symbol associated with the overlap between the first uplink channel transmission and the second uplink channel transmission,

wherein the symbol associated with the overlap is based on timing related to receiving the downlink channel transmission carrying the downlink control information format.

2. The apparatus of claim 1 , wherein the apparatus comprises a user equipment (UE).

3. The apparatus of claim 1 , wherein the symbol comprises an initial symbol associated with the overlap between the first uplink channel transmission and the second uplink channel transmission.

4. The apparatus of claim 1 , wherein the first uplink channel transmission comprises a first physical uplink control channel (PUCCH) transmission, and wherein the second uplink channel transmission comprises a second physical uplink shared channel (PUSCH) transmission or a second PUCCH transmission.

5. The apparatus of claim 4 , wherein the instructions are further executable by the processor to cause the apparatus to:

cancel the second PUSCH transmission or the second PUCCH transmission before the symbol associated with the overlap between the first PUCCH transmission and the second PUSCH transmission or the second PUCCH transmission.

6. The apparatus of claim 1 , wherein the first uplink channel transmission comprises a first physical uplink shared channel (PUSCH) transmission, and wherein the second uplink channel transmission comprises a second PUSCH transmission or a second physical uplink control channel (PUCCH) transmission.

7. The apparatus of claim 6 , wherein the instructions are further executable by the processor to cause the apparatus to:

cancel the second PUSCH transmission or the second PUCCH transmission before the symbol associated with the overlap between the first PUSCH transmission and the second PUSCH transmission or the second PUCCH transmission.

8. The apparatus of claim 1 , wherein the instructions are further executable by the processor to cause the apparatus to:

determine a last symbol associated with the downlink channel transmission; and

determine an initial symbol associated with the first uplink channel transmission based at least in part on the last symbol associated with the downlink channel transmission.

9. The apparatus of claim 8 , wherein the instructions are further executable by the processor to cause the apparatus to:

determine an uplink channel preparation time associated with the first uplink channel transmission; and

determine the initial symbol associated with the first uplink channel transmission based at least in part on the last symbol associated with the downlink channel transmission and the uplink channel preparation time associated with the first uplink channel transmission,

wherein the second uplink channel transmission is canceled based on the initial symbol.

10. A processor comprising:

a controller coupled with a memory and configured to cause the processor to:

receive a downlink channel transmission carrying a downlink control information format that schedules a first uplink channel transmission;

determine an overlap between the first uplink channel transmission and a second uplink channel transmission, wherein the first uplink channel transmission is associated with a first priority, wherein the second uplink channel transmission is associated with a second priority different than the first priority; and

cancel the second uplink channel transmission before a symbol associated with the overlap between the first uplink channel transmission and the second uplink channel transmission,

wherein the symbol associated with the overlap is based on timing related to receiving the downlink channel transmission carrying the downlink control information format.

11. The processor of claim 10 , wherein the symbol comprises an initial symbol associated with the overlap between the first uplink channel transmission and the second uplink channel transmission.

12. The processor of claim 10 , wherein the first uplink channel transmission comprises a first physical uplink control channel (PUCCH) transmission, and wherein the second uplink channel transmission comprises a second physical uplink shared channel (PUSCH) transmission or a second PUCCH transmission.

13. The processor of claim 12 , wherein the controller is further configured to cause the processor to:

cancel the second PUSCH transmission or the second PUCCH transmission before the symbol associated with the overlap between the first PUCCH transmission and the second PUSCH transmission or the second PUCCH transmission.

14. The processor of claim 10 , wherein the first uplink channel transmission comprises a first physical uplink shared channel (PUSCH) transmission, and wherein the second uplink channel transmission comprises a PUSCH transmission or a second physical uplink control channel (PUCCH) transmission.

15. The processor of claim 14 , wherein the controller is further configured to cause the processor to:

cancel the second PUSCH transmission or the second PUCCH transmission before the symbol associated with the overlap between the first PUSCH transmission and the second PUSCH transmission or the second PUCCH transmission.

16. The processor of claim 10 , wherein the controller is further configured to cause the processor to:

determine a last symbol associated with the downlink channel transmission; and

determine an initial symbol associated with the first uplink channel transmission based at least in part on the last symbol associated with the downlink channel transmission.

17. The processor of claim 16 , wherein the controller is further configured to cause the processor to:

determine an uplink channel preparation time associated with the first uplink channel transmission; and

determine the initial symbol associated with the first uplink channel transmission based at least in part on the last symbol associated with the downlink channel transmission and the uplink channel preparation time associated with the first uplink channel transmission,

wherein the second uplink channel transmission is canceled based on the initial symbol.

18. A method of wireless communication at a user equipment (UE), the method comprising:

receiving a downlink channel transmission carrying a downlink control information format that schedules a first uplink channel transmission;

determining an overlap between the first uplink channel transmission and a second uplink channel transmission, wherein the first uplink channel transmission is associated with a first priority, wherein the second uplink channel transmission is associated with a second priority different than the first priority; and

canceling the second uplink channel transmission, before a symbol associated with the overlap between the first uplink channel transmission and the second uplink channel transmission,

wherein the symbol associated with the overlap is based on timing related to receiving the downlink channel transmission carrying the downlink control information format.

19. The method of claim 18 , further comprising:

determining a last symbol associated with the downlink channel transmission; and

determining an initial symbol associated with the first uplink channel transmission based at least in part on the last symbol associated with the downlink channel transmission.

20. The method of claim 19 , further comprising:

determining an uplink channel preparation time associated with the first uplink channel transmission; and

determining the initial symbol associated with the first uplink channel transmission based at least in part on the last symbol associated with the downlink channel transmission and the uplink channel preparation time associated with the first uplink channel transmission,
