Method and device in ue and base station used for multi-antenna transmission

A method in a second node used for multi-antenna transmission, comprising:

• 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 is used for determining a second radio resource;
• 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.
