A method, apparatus, and computer program for acquiring transmission resources during a transmission period is provided. A first communication apparatus is arranged to utilize at least a second communication apparatus to reserve at least one additional transmission band for the first communication apparatus during the transmission period of the first communication apparatus. The first communication apparatus is configured to increase its transmission band during the transmission period upon successful exchange of transmission request and transmission permission messages, wherein the transmission request and transmission permission messages are used to identify available additional transmission bands. |
