Claim 5:
6. A method in a second node used for multi-antenna transmission, comprising:
transmitting Q1 pieces of second downlink information and Q2 pieces of third downlink information, wherein the Q1 pieces of second downlink information are respectively used for determining Q1 first-type radio resources and Q1 first-type identifiers, the Q1 first-type identifiers respectively correspond to the Q1 first-type radio resources, the Q2 pieces of third downlink information are respectively used for determining Q2 second-type radio resources and Q2 second-type identifiers, the Q2 second-type identifiers respectively correspond to the Q2 second-type radio resources, Q1 and Q2 are positive integers greater than 1, respectively; and
transmitting first downlink information;
wherein the first downlink information is an information element, the first downlink information comprises a first field and a second field, the first field of the first downlink information is used for determining a first radio resource, the second field of the first downlink information indicates a second identifier of the Q2 second-type identifiers, the second identifier corresponds to a second radio resource in the Q2 second-type radio resources;
the first radio resource is reserved for a first-type reference signal, the second radio resource is reserved for a second-type reference signal; a transmitter of the first-type reference signal is the second node, a target receiver of the second-type reference signal comprises the second node; a measurement on the first-type reference signal is used for generating the second-type reference signal; the second node is a base station, wherein the first downlink information further comprises a fourth field, the fourth field of the first downlink information is used for identifying the information element.
