1. A method comprising:

  • determining a virtual transmission time interval for a medium access control entity of an apparatus;

    checking to determine whether the medium access control entity is transmitting data packets from the apparatus in a current air interface transmission time interval; and

    for the case where it is determined that the medium access control entity is not transmitting from the apparatus in the current air interface transmission time interval, transmitting a next data packet from the apparatus after a predetermined period associated with the virtual transmission time interval has elapsed, wherein the next data packet comprises at least one protocol data unit and the virtual transmission time interval is an integer multiple of the current air interface transmission time interval.
