Beamforming with multiple panels in a radio system

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 a medium access control element (MAC CE) comprising:
• a plurality of first bit fields corresponding to a plurality of antenna panels, wherein each first bit field comprises one or more bits indicating activation or deactivation of a corresponding antenna panel;
• and
• a plurality of second bit fields corresponding to a plurality of transmission configuration indication (TCI) state indexes, wherein each second bit field comprises one or more bits indicating activation or deactivation of at least one TCI state in every activated antenna panel of the plurality of antenna panels;
• receive a downlink control information (DCI) indicating a TCI state index of the plurality of TCI state indexes;
• determine, based on the MAC CE, that the TCI state index indicated by the DCI corresponds to:
• a first TCI state of a first activated antenna panel;
• and
• a second TCI state of a second activated antenna panel;
• transmit, via the first activated antenna panel, one or more first transport blocks based on the first TCI state;
• and
• transmit, via the second activated antenna panel, one or more second transport blocks based on the second TCI state.

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

• receive a medium access control element (MAC CE) comprising:
• a plurality of first bit fields corresponding to a plurality of antenna panels, wherein each first bit field comprises one or more bits indicating activation or deactivation of a corresponding antenna panel;
• and
• a plurality of second bit fields corresponding to a plurality of transmission configuration indication (TCI) state indexes, wherein each second bit field comprises one or more bits indicating activation or deactivation of at least one TCI state in every activated antenna panel of the plurality of antenna panels;
• receive a downlink control information (DCI) indicating a TCI state index of the plurality of TCI state indexes;
• determine, based on the MAC CE, that the TCI state index indicated by the DCI corresponds to:
• a first TCI state of a first activated antenna panel;
• and
• a second TCI state of a second activated antenna panel;
• transmit, via the first activated antenna panel, one or more first transport blocks based on the first TCI state;
• and
• transmit, via the second activated antenna panel, one or more second transport blocks based on the second TCI state.
