Method and device used in ue and base station for wireless communication

A base station for wireless communications, comprising:

• a second transmitter, which transmits a first signaling, the first signaling indicating N1 time-frequency resource blocks;
• and
• a second transceiver, which processes N radio signals respectively in N time-frequency resource blocks;
• wherein the N1 time-frequency resource blocks respectively belong to N1 frequency sub-bands in frequency domain, any two frequency sub-bands of the N1 frequency sub-bands being orthogonal, N1 being a positive integer greater than 1;
• any time-frequency resource block of the N time-frequency resource blocks is one of the N1 time-frequency resource blocks, N being a positive integer greater than 1 and no greater than the N1;
• the N radio signals respectively comprise N first-type reference signals, and an antenna port for transmitting each of the N first-type reference signals is associated with a first antenna port;
• a first target signal is any first-type reference signal of the N first-type reference signals, and frequency density of the first target signal is related to only a target time-frequency resource block of the N1 time-frequency resource blocks, the target time-frequency resource block being one of the N1 time-frequency resource blocks;
• the processing action is receiving, or, the processing action is transmitting.
