Feedback Transmission with Multiple Transmission Reception Points

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 plurality of downlink control information (DCIs) via a plurality of resource block (RB) sets of a bandwidth part of a cell, wherein the plurality of DCIs indicate downlink radio resources;
• receive a transport block via the downlink radio resources;
• determine, based on RB set indexes of the plurality of RB sets, 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.

A system comprising:

• a base station comprising:
• one or more first processors and first memory storing first instructions that, when executed by the one or more first processors, cause the base station to:
• transmit a plurality of downlink control information (DCIs) via a plurality of resource block (RB) sets of a bandwidth part of a cell, wherein the plurality of DCIs indicate downlink radio resources;
• and
• a wireless device comprising:
• one or more second processors and second memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:
• receive, from the base station, the plurality of DCIs via the plurality of resource block (RB) sets of the bandwidth part of the cell;
• receive, from the base station, a transport block via the downlink radio resources;
• determine, based on RB set indexes of the plurality of RB sets, a DCI from the plurality of DCIs;
• and
• transmit feedback information, for the transport block, to the base station via an uplink control channel resource determined based on the DCI.
