1. A method, comprising:
receiving downlink control information (DCI) including beam indication information, wherein the beam indication information indicates:
one or more temporal units in a sequence of 14 symbols in a slot;
for each of the one or more temporal units, an indication of an uplink or downlink direction of data flow during that temporal interval; and
a first beam pattern from a predetermined list of multiple beam patterns, wherein each beam pattern of the predetermined list of beam patterns specifies a respective beam index for each respective temporal unit of the slot, wherein each beam pattern includes changing beams at least once during the slot and at least a subset of the beam patterns of the predetermined list of beam patterns includes using at least 3 different beams during the slot.
