The wireless device transmits a random-access preamble for the random-access procedure. The wireless device receives a downlink control information (DCI), scheduling a random-access response corresponding to the random-access preamble, via a second coreset with a second coreset group index. Reception of the DCI is based on: a first transmission configuration indicator (TCI) state of the first coreset when the first coreset group index is the same as the second coreset group index, and a second TCI state of the second coreset when the first coreset group index is different from the second coreset group index. ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 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 one or more messages comprising one or more configuration parameters, wherein the one or more configuration parameters indicate: a first control resource set (coreset) group index for one or more first coresets; and a second coreset group index for one or more second coresets; receive, via a first coreset of the one or more first coresets, a physical downlink control channel (PDCCH) order triggering a random-access procedure; transmit a random-access preamble for the random-access procedure; and receive, via a second coreset associated with a Type1 PDCCH common search space (CSS) set with the second coreset group index, downlink control information (DCI) scheduling a random-access response corresponding to the random-access preamble, wherein: based on the first coreset group index, of the first coreset that the wireless device receives the PDCCH order being different from the second coreset group index, the DCI is received using demodulation reference signal (DM-RS) antenna port quasi co-location properties of the second coreset associated with the Type1 PDCCH CSS set;
