Data transmissions using multiple transmission reception points

An apparatus comprising:

• a transmitter that:
• transmits a downlink control information format in a downlink control channel to a user equipment, wherein:
• the downlink control information format comprises a transmission configuration indication field;
• the transmission configuration indication field indicates two transmission configuration indication states;
• and
• each transmission configuration indication state of the two transmission configuration indication states contains parameters for configuring a quasi-colocation relationship associating at least one downlink reference signal resource with a demodulation reference signal of a downlink data channel;
• and
• transmits the downlink data channel from two transmission reception points, wherein each transmission reception point of the two transmission reception points transmits each data layer of one or more data layers and a demodulation reference signal associated with each data layer.

An apparatus comprising:

• a receiver that:
• receives a downlink control information format in a downlink control channel from a network unit, wherein:
• the downlink control information format comprises a transmission configuration indication field;
• the transmission configuration indication field indicates two transmission configuration indication states;
• and
• each transmission configuration indication state of the two transmission configuration indication states contains parameters for configuring a quasi-colocation relationship associating at least one downlink reference signal resource with a demodulation reference signal of a downlink data channel;
• and
• receives the downlink data channel, wherein each data layer of one or more data layers and a demodulation reference signal associated with each data layer is associated with the two transmission configuration indication states.
