Feedback transmission with multiple transmission reception points
In some embodiments, a wireless device receives a plurality of downlink control information (DCIs) via a plurality of resource block (RB) sets of a bandwidth part of a cell. The plurality of DCIs indicate downlink radio resources. The wireless device receives a transport block via the downlink radio resources. Based on RB set indexes of the plurality of RB sets, the wireless device determines a DCI from the plurality of DCIs. Then, the wireless device transmits feedback information, for the transport block, via an uplink control channel resource determined based on the DCI.

10. The method of claim 6 , wherein the first DCIs and the second DCIs comprise same downlink radio resources for the transport block.
11. 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 transport block via the one or more downlink radio resources;
determine, based on RB set indexes of the plurality of RB sets of the bandwidth part of the cell, a DCI from the plurality of DCIs; and
transmit feedback information, for the transport block, via an uplink control channel resource determined based on the DCI.
12. The wireless device of claim 11 , wherein each DCI of the plurality of DCIs is received via a respective RB set of the plurality of RB sets.
13. The wireless device of claim 11 , wherein the instructions further cause the wireless device to index the plurality of DCIs based on the RB set indexes of the plurality of RB sets.
14. The wireless device of claim 13 , wherein the plurality of DCIs are indexed in an order of the RB set indexes of the plurality of RB sets.
15. The wireless device of claim 13 , wherein the DCI is determined as a DCI, among the plurality of DCIs, having a highest index among indexes of the plurality of DCIs.
16. The wireless device of claim 11 , wherein the plurality of DCIs comprise:
one or more first DCIs received via a first control resource set associated with a first control resource set pool index; and
one or more second DCIs received via a second control resource set associated with a second control resource set pool index.
17. The wireless device of claim 16 , wherein the instructions further cause the wireless device to index the plurality of DCIs in an order of control resource set pool indexes.
18. The wireless device of claim 16 , wherein one or more DCIs are determined further based on a corresponding control resource set pool index.
19. The wireless device of claim 16 , wherein the instructions further cause the wireless device to index the plurality of DCIs first in an ascending order of the RB set indexes with a same control resource set pool index and second in an ascending order of control resource set pool indexes.
