1. A method, comprising:
- acquiring, in a first wireless communication apparatus, a transmission period to transmit data on a first frequency band within a determined transmission time interval;
determining to utilize a bandwidth higher than that of the first frequency band during the transmission period;
causing transmission of a reservation request message to at least second wireless communication apparatus, wherein the reservation request message instructs the second wireless communication apparatus to reserve at least one additional frequency band for the first wireless communication apparatus during the transmission period;
receiving a reservation response message from the at least second wireless communication apparatus, wherein the reservation response message indicates that said at least one additional frequency band is available for the first wireless communication apparatus to use in transmission during the transmission period; and
in response to the reception of the reservation response message, increasing transmission band to comprise said first frequency band and said at least one additional frequency band during the transmission period.

Abstract
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 one other communication apparatus to reserve at least one additional transmission band for the first communication apparatus during the transmission period of the first communication apparatus. Upon reception of a message indicating availability of additional transmission band(s) from the at least one other communication apparatus, the first communication apparatus is configured to increase its transmission band during the transmission period.
