Transmission configuration indication state partitioning in multi-beam scenarios

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 downlink control information (DCI), wherein the DCI indicates a resource for reception of a transport block;
• select a transmission configuration indicator (TCI) state among a first TCI state associated with a first set of transmission time intervals (TTIs) and a second TCI state associated with a second set of TTIs, based on which of the first set of TTIs or the second set of TTIs overlaps in time with the resource indicated by the DCI;
• and
• receive the transport block via the resource based on the selected TCI state.

A system comprising:

• a base station;
• 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 downlink control information (DCI) indicating a resource for reception of a transport block;
• 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 the DCI;
• select, for reception of the transport block, a transmission configuration indicator (TCI) state among a first TCI state associated with a first set of transmission time intervals (TTIs) and a second TCI state associated with a second set of TTIs, based on which of the first set of TTIs or the second set of TTIs overlaps in time with the resource indicated by the DCI;
• and
• receive, from the base station and based on the selected TCI state, the transport block via the resource.
