Abstract: A new air interface that is interference cancellation friendly is proposed. In one novel aspect, a base station uses one subband as the basic scheduling unit for each transport block if CWIC is configured, e.g., by static or semi-static signaling. By the use of proper bit selection and resource element mapping, the coded bits of a same code block are transmitted in the same subband. The transmission of a subband includes an integer multiple number of code blocks. As a result, only interfering code blocks at subbands co-scheduled with desired transport blocks are decoded and cancelled.
