Interrupted transmission in control channel repetition
A wireless device may receive a physical downlink control channel (PDCCH) with first downlink control information (DCI) scheduling an uplink transmission. The wireless device may receive, via at least one PDCCH monitoring occasion of PDCCH monitoring occasions, a repetition of second DCI that indicates cancelation of one or more symbols of the uplink transmission. The wireless device may cancel the one or more symbols of the uplink transmission based on a last symbol of the PDCCH reception with the first DCI being earlier than a starting symbol of the PDCCH monitoring occasions.
1. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive a radio resource control (RRC) message comprising one or more configuration parameters, wherein:
the one or more configuration parameters indicate two search space sets for physical downlink control channel (PDCCH) repetition; and
each search space set of the two search space sets is associated with a respective control resource set (coreset) of two coresets;
receive, in one or more first symbols, a PDCCH with first downlink control information (DCI) scheduling an uplink transmission;
receive, via at least one PDCCH monitoring occasion of PDCCH monitoring occasions of PDCCH candidates corresponding to the two search space sets, second DCI that indicates cancelation of one or more symbols of the uplink transmission, wherein the second DCI is being repeated in the PDCCH monitoring occasions; and
cancel, based on a last symbol of the PDCCH reception with the first DCI being earlier than a starting symbol of the PDCCH monitoring occasions, the one or more symbols of the uplink transmission, wherein the last symbol is a latest symbol in time among the one or more first symbols.
2. The wireless device of claim 1 , wherein the two coresets comprise:
a first coreset associated with a first search space set of the two search space sets; and
a second coreset associated with a second search space set of the two search space sets.
3. The wireless device of claim 2 , wherein:
a first duration of the first coreset and a second duration of the second coreset of the two coresets are the same; and
a first number of control channel elements (CCEs) of the first coreset and a second number of CCEs of the second coreset are the same.
4. The wireless device of claim 3 , wherein the PDCCH monitoring occasions are in a slot.
5. The wireless device of claim 4 , wherein the uplink transmission is at least one of:
a physical uplink shared channel (PUSCH) transmission; or
a sounding reference signal (SRS) transmission.
6. The wireless device of claim 5 , wherein the one or more configuration parameters comprise an uplink cancelation parameter for canceling the one or more symbols.
7. The wireless device of claim 6 , wherein the instructions further cause the wireless device to cancel the one or more symbols by not performing the uplink transmission in at least one symbol of the one or more symbols.
8. The wireless device of claim 7 , wherein the instructions further cause the wireless device to monitor, in the PDCCH monitoring occasions, the PDCCH candidates for a DCI format, wherein each repetition of the DCI format has the same payload.
9. The wireless device of claim 8 , wherein the instructions further cause the wireless device to:
receive a PDCCH with third DCI scheduling a second uplink transmission;
receive, via at least one second PDCCH monitoring occasion of second PDCCH monitoring occasions of second PDCCH candidates corresponding to the two search space sets, fourth DCI that indicates cancelation of one or more second symbols of the second uplink transmission; and
not canceling, based on a last symbol of the PDCCH reception with the third DCI not being earlier than a starting symbol of the second PDCCH monitoring occasions, the one or more second symbols of the second uplink transmission.
10. The wireless device of claim 9 , wherein the not cancelling the one or more second symbols of the second uplink transmission comprises performing the second uplink transmission in the one or more second symbols.
11. The wireless device of claim 1 , wherein the instructions further cause the wireless device to:
receive a PDCCH with third DCI scheduling a second uplink transmission;
receive, via at least one second PDCCH monitoring occasion of second PDCCH monitoring occasions of second DCCH candidates corresponding to the two search space sets, fourth DCI that indicates cancelation of one or more second symbols of the second uplink transmission; and
not canceling, based on a last symbol of the PDCCH reception with the third DCI not being earlier than a starting symbol of the second PDCCH monitoring occasions, the one or more second symbols of the second uplink transmission.
12. The wireless device of claim 11 , wherein the not cancelling the one or more second symbols of the second uplink transmission comprises performing the second uplink transmission in the one or more second symbols.
13. The wireless device of claim 12 , wherein the two coresets comprise:
a first coreset associated with a first search space set of the two search space sets; and
a second coreset associated with a second search space set of the two search space sets.
14. The wireless device of claim 13 , wherein:
a first duration of the first coreset and a second duration of the second coreset of the two coresets are the same; and
a first number of control channel elements (CCEs) of the first coreset and a second number of CCEs of the second coreset are the same.
15. The wireless device of claim 14 , wherein the PDCCH monitoring occasions are in a slot.
16. The wireless device of claim 15 , wherein the uplink transmission is at least one of:
a physical uplink shared channel (PUSCH) transmission; or
a sounding reference signal (SRS) transmission.
17. The wireless device of claim 1 , wherein:
a first duration of the first coreset and a second duration of the second coreset of the two coresets are the same; and
a first number of control channel elements (CCEs) of the first coreset and a second number of CCEs of the second coreset are the same.
18. The wireless device of claim 17 , wherein the one or more configuration parameters comprise an uplink cancelation parameter for canceling the one or more symbols.
19. The wireless device of claim 18 , wherein the instructions further cause the wireless device to:
receive a PDCCH with third DCI scheduling a second uplink transmission;
receive, via at least one second PDCCH monitoring occasion of second PDCCH monitoring occasions of second DCCH candidates corresponding to the two search space sets, fourth DCI that indicates cancelation of one or more second symbols of the second uplink transmission; and
not canceling, based on a last symbol of the PDCCH reception with the third DCI not being earlier than a starting symbol of the second PDCCH monitoring occasions, the one or more second symbols of the second uplink transmission.
20. The wireless device of claim 19 , wherein the not cancelling the one or more second symbols of the second uplink transmission comprises performing the second uplink transmission in the one or more second symbols.
