Embodiments of the present disclosure relate to a method, device and computer readable storage medium of communication. The method implemented at a first device comprises receiving, from a second device, a first configuration about a first measurement of first downlink reference signals of the second device and a second configuration about a second measurement of second downlink reference signals of a third device; determining, based on an active bandwidth part of the first device and the first and second configurations, first information for the first measurement and second information for the second measurement; determining a first result of the first measurement based on the first information and a second result of the second measurement based on the second information; and transmitting the first result and the second result to the second device.
