Pusch multiple trp reliability with ul tci indication

A method performed by a base station, the method comprising:

• transmitting, to a wireless device, a configuration of Transmission Configuration Indicator (TCI) states for Physical Uplink Shared Channel (PUSCH) transmission, wherein the configuration is transmitted via radio resource control (RRC) signaling;
• transmitting, to the wireless device, a downlink control information (DCI) message comprising a bit field, wherein a mapping applies between code points of the bit field and configured TCI states such that:
• a first code point of the bit field is mapped to a first TCI state and a second TCI state;
• and
• a second code point of the bit field is mapped to the first TCI state;
• when the DCI message comprises the first code point in the bit field, receiving a plurality of PUSCH transmission occasions, where a first subset of the PUSCH transmission occasions is associated with the first TCI state, and where a second subset of the PUSCH transmission occasions is associated with the second TCI state;
• and
• when the DCI message comprises the second code point in the bit field, receiving the plurality of PUSCH transmission occasions, where the PUSCH transmission occasions are associated with the first TCI state.

A wireless device comprising:

• one or more transmitters;
• one or more receivers;
• and
• processing circuitry associated with the one or more transmitters and the one or more receivers, the processing circuitry configured to cause the wireless device to:
• receive a configuration of Transmission Configuration Indicator (TCI) states for Physical Uplink Shared Channel (PUSCH) transmission, wherein the configuration is received via radio resource control (RRC) signaling;
• receive a downlink control information (DCI) message comprising a bit field, wherein a mapping applies between code points of the bit field and configured TCI states such that:
• a first code point of the bit field is mapped to a first TCI state and a second TCI state;
• and
• a second code point of the bit field is mapped to the first TCI state;
• when the DCI message comprises the first code point in the bit field, transmit a plurality of PUSCH transmission occasions, where a first subset of the PUSCH transmission occasions is associated with the first TCI state, and where a second subset of the PUSCH transmission occasions is associated with the second TCI state;
• and
• when the DCI message comprises the second code point in the bit field, transmitting the plurality of PUSCH transmission occasions, where the PUSCH transmission occasions are associated with the first TCI state.
