Method and device in ue and base station for wireless communication

A method in a base station for wireless communication, comprising in turn:

• transmitting first control information, the first control information being used for indicating a first multiple access signature sequence, the first multiple access signature sequence comprising a first multiple access signature and a second multiple access signature in turn;
• receiving a first radio signal, the first radio signal occupying a first RE set, and the first multiple access signature being used for generating the first radio signal based on a first bit block;
• and
• receiving a second radio signal, the second radio signal occupying a second RE set, the first RE set being orthogonal to the second RE set, and the second multiple access signature being used for generating the second radio signal based on a second bit block.

A UE for wireless communication, comprising in turn:

• a first receiver module, to receive first control information, the first control information being used for indicating a first multiple access signature sequence, the first multiple access signature sequence comprising a first multiple access signature and a second multiple access signature in turn;
• a second transmitter module, to transmit a first radio signal, the first radio signal occupying a first RE set, and the first multiple access signature being used for generating the first radio signal based on a first bit block;
• and
• a third transmitter module, to transmit a second radio signal, the second radio signal occupying a second RE set, the first RE set being orthogonal to the second RE set, and the second multiple access signature being used for generating the second radio signal based on a second bit block.
