Reliability for beam failure recovery and search space and control resource set index 0

A method, comprising:

• by a cellular base station:
• determining a search space (SS) and control resource set (CORESET) index 0 configuration for a wireless link with a wireless device, wherein the SS and CORESET index 0 configuration supports single frequency network (SFN) physical downlink control channel (PDCCH) repetitions, wherein the SFN PDCCH repetitions have different active transmission configuration indicator (TCI) states and are to be received in the same SS;
• and
• providing multiple PDCCH repetitions to the wireless device in accordance with the SS and CORESET index 0 configuration and the different active TCI states, wherein providing according to the different active TCI states is not applicable to a type0 common SS.

A cellular base station, comprising:

• an antenna;
• a radio coupled to the antenna;
• and a processor operably coupled to the radio,
• wherein the cellular base station is configured to:
• determine a search space (SS) and control resource set (CORESET) index 0 configuration for a wireless link with a wireless device, wherein the SS and CORESET index 0 configuration supports single frequency network (SFN) physical downlink control channel (PDCCH) repetitions wherein the SFN PDCCH repetitions have different active transmission configuration indicator (TCI) states and are to be received in the same SS;
• and
• providing multiple PDCCH repetitions to the wireless device in accordance with the SS and CORESET index 0 configuration and the different active TCI states, wherein providing according to the different active TCI states is not applicable to a type° common SS.
