Random Access Procedure in Multiple Transmission and 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 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;
• and
• based on the first coreset group index being the same as the second coreset group index, the DCI is received using DM-RS antenna port quasi co-location properties of the PDCCH order.
