A method and apparatus for a transmitter having a radio protocol with an
upper layer and a lower layer therein used for management of full header
transmission when transmitting data packets to a receiver are provided.
The method comprises controlling a transmission of a full header packet
by information from the lower layer, whereby, if the upper layer receives
from the lower layer, information of a failed transmission of at least
one packet, the upper layer decides whether to send a next packet as a
full header packet.
