Beam Management in Multiple Transmission and Reception Points

A base station comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the base station to:
• transmit, to a wireless device, one or more radio resource control (RRC) configuration parameters indicating an index for one or more sounding reference signal (SRS) resources, wherein:
• a first value of the index indicates to apply a first transmission configuration indicator (TCI) state associated with a first control resource set (coreset) pool index to first transmissions via the one or more SRS resources;
• and
• a second value of the index indicates to apply a second TCI state associated with a second coreset pool index to second transmissions via the one or more SRS resources;
• and
• receiving, via the one or more SRS resources, an SRS based on a TCI state, among the first TCI state and the second TCI state, associated with the index.

A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:

• receive one or more radio resource control (RRC) configuration parameters indicating an index for one or more sounding reference signal (SRS) resources, wherein:
• a first value of the index indicates to apply a first transmission configuration indicator (TCI) state associated with a first control resource set (coreset) pool index to first transmissions via the one or more SRS resources;
• and
• a second value of the index indicates to apply a second TCI state associated with a second coreset pool index to second transmissions via the one or more SRS resources;
• and
• transmit, via the one or more SRS resources, an SRS using a TCI state, among the first TCI state and the second TCI state, determined based on the index.
