Wireless resource determination and use
Wireless resource determination and use are described. A wireless device may determine to use a resource (e.g., PUCCH resource), indicated by control information (e.g., DCI), for sending an acknowledgement (e.g., HARQ-ACK feedback) of a reception of data (e.g., at least one transport block). The control information may be received in a message of a plurality of messages. The wireless device may select the control information (e.g., for determining the resource) from among other control information in the plurality of messages, based on one or more factors.
1. A method comprising:
receiving, by a wireless device:
via a first control resource set (CORESET) associated with a first search space set identified by a first search space set index, first downlink control information (DCI); and
via a second CORESET associated with a second search space set identified by a second search space set index, second DCI;
determining a physical uplink control channel (PUCCH) resource based on the first DCI, wherein the first DCI is selected based on the first search space set index being lower than the second search space set index; and
transmitting, via the PUCCH resource, hybrid automatic repeat request acknowledgement (HARQ-ACK) information corresponding to downlink reception scheduled by the first DCI.
2. The method of claim 1 , wherein the HARQ-ACK information further corresponds to downlink reception scheduled by the second DCI.
3. The method of claim 1 , wherein the determining the PUCCH resource based on the first DCI comprises determining the PUCCH resource based on a PUCCH resource indicator field in the first DCI.
4. The method of claim 1 , wherein the first DCI or the second DCI indicates scheduling information for reception of a transport block (TB).
5. The method of claim 1 , wherein:
the receiving the first DCI comprises receiving the first DCI during a first PDCCH monitoring occasion; and
the receiving the second DCI comprises receiving the second DCI during a second PDCCH monitoring occasion.
6. The method of claim 1 , wherein the first DCI and the second DCI indicate an uplink time slot for transmission of the HARQ-ACK information.
7. The method of claim 1 , wherein the first DCI is further selected based on at least one of:
a priority parameter of the first DCI; or
a service type of the first DCI.
8. 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:
via a first control resource set (CORESET) associated with a first search space set identified by a first search space set index, first downlink control information (DCI); and
via a second CORESET associated with a second search space set identified by a second search space set index, second DCI;
determine a physical uplink control channel (PUCCH) resource based on the first DCI, wherein the first DCI is selected based on the first search space set index being lower than the second search space set index; and
transmit, via the PUCCH resource, hybrid automatic repeat request acknowledgement (HARQ-ACK) information corresponding to downlink reception scheduled by the first DCI.
9. The wireless device of claim 8 , wherein the HARQ-ACK information further corresponds to downlink reception scheduled by the second DCI.
10. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, cause the wireless device to determine the PUCCH resource based on the first DCI by causing determining the PUCCH resource based on a PUCCH resource indicator field in the first DCI.
11. The wireless device of claim 8 , wherein the first DCI or the second DCI indicates scheduling information for reception of a transport block (TB).
12. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, cause the wireless device to:
receive the first DCI by causing receiving the first DCI during a first PDCCH monitoring occasion; and
receive the second DCI by causing receiving the second DCI during a second PDCCH monitoring occasion.
13. The wireless device of claim 8 , wherein the first DCI and the second DCI indicate an uplink time slot for transmission of the HARQ-ACK information.
14. The wireless device of claim 8 , wherein the first DCI is further selected based on at least one of:
a priority parameter of the first DCI; or
a service type of the first DCI.
15. A non-transitory computer readable medium storing instructions that, when executed, cause:
receiving, by a wireless device:
via a first control resource set (CORESET) associated with a first search space set identified by a first search space set index, first downlink control information (DCI); and
via a second CORESET associated with a second search space set identified by a second search space set index, second DCI;
determining a physical uplink control channel (PUCCH) resource based on the first DCI, wherein the first DCI is selected based on the first search space set index being lower than the second search space set index; and
transmitting, via the PUCCH resource, hybrid automatic repeat request acknowledgement (HARQ-ACK) information corresponding to downlink reception scheduled by the first DCI.
16. The non-transitory computer readable medium of claim 15 , wherein the HARQ-ACK information further corresponds to downlink reception scheduled by the second DCI.
17. The non-transitory computer readable medium of claim 15 , wherein the instructions, when executed, cause determining the PUCCH resource based on the first DCI by causing determining the PUCCH resource based on a PUCCH resource indicator field in the first DCI.
18. The non-transitory computer readable medium of claim 15 , wherein the first DCI or the second DCI indicates scheduling information for reception of a transport block (TB).
19. The non-transitory computer readable medium of claim 15 , wherein the instructions, when executed, cause:
receiving the first DCI by causing receiving the first DCI during a first PDCCH monitoring occasion; and
receiving the second DCI by causing receiving the second DCI during a second PDCCH monitoring occasion.
20. The non-transitory computer readable medium of claim 15 , wherein the first DCI and the second DCI indicate an uplink time slot for transmission of the HARQ-ACK information.
21. The non-transitory computer readable medium of claim 15 , wherein the first DCI is further selected based on at least one of:
a priority parameter of the first DCI; or
a service type of the first DCI.
22. The method of claim 1 , wherein the determining the PUCCH resource based on the first DCI comprises comparing the first search space set index with the second search space set index.
23. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, cause the wireless device to determine the PUCCH resource based on the first DCI by causing comparing the first search space set index with the second search space set index.
24. The non-transitory computer readable medium of claim 15 , wherein the instructions, when executed, cause determining the PUCCH resource based on the first DCI by causing comparing the first search space set index with the second search space set index.
