17. An apparatus for feeding back layer information, comprising:
one or more processors; and
one or more memories storing a computer program that when executed by the one or more processors cause the one or more processors to perform operations, the operations comprising:
receiving configuration information of a first communication node;
determining layer information of the first communication node according to the configuration information; and
feeding back the layer information to the first communication node;
determining a transmission rank order according to the layer information;
wherein the layer information comprises layer received strength, a layer delay and a layer index number; and
the transmission rank order comprises at least one of: a layer reporting order, an order of layers in a reporting sequence, a layer priority or a layer index number or
the transmission rank order comprises at least one of: a layer reporting order, an order of layers in a reporting sequence or a layer priority;
wherein the determining a transmission rank order according to the layer information comprises at least one of the following:
determining the transmission rank order according to a configuration order of the layer index number; or
determining the transmission rank order according to a reporting order of the layer index number;
wherein the feeding back the layer information to the first communication node comprises:
reporting layer information of a second preset number of layers with a lowest layer delay to the first communication node.
