1. A method performed by a base station, the method comprising:
transmitting 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 number of demodulation reference signals associated with a downlink data channel; and
transmitting the downlink data channel from two transmission reception points, wherein:
a first transmission reception point of the two transmission reception points transmits each data layer of a plurality of data layers;
a second transmission reception point of the two transmission reception points transmits each data layer of the plurality of data layers; and
each transmission reception point of the two transmission reception points transmits a demodulation reference signal associated with each data layer of the plurality of data layers, the demodulation reference signal comprising a demodulation reference signal of the number of demodulation reference signals, and the demodulation reference signal of each data layer of the plurality of data layers is associated with two channel state information reference signal (CSI-RS) resources.
