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

A base station for wireless communications, comprising:

• a second transmitter, transmitting first information, the first information being used to indicate M frequency-domain resource blocks in N frequency subbands;
• and
• a second receiver, receiving a first radio signal in M1 frequency-domain resource block(s) in the N1 frequency subband(s);
• wherein any of the M frequency-domain resource blocks belongs to one of the N frequency subbands, any of the N frequency subbands comprises at least one of the M frequency-domain resource blocks;
• the M1 frequency-domain resource block(s) is(are) M1 frequency-domain resource block(s) belonging to the N1 frequency subband(s) in the M frequency-domain resource blocks;
• any two of the N frequency subbands are orthogonal, and any two of the M frequency-domain resource blocks are orthogonal in frequency domain;
• a first power value is used to determine transmit power of the first radio signal;
• the first power value is related to the N1, or, the first power value is related to the M1;
• N is a positive integer number greater than 1, M is a positive integer greater than 1, N1 is a positive integer not greater than the N, and M1 is a positive integer not greater than the M.
