A data packet communication system employs radio link control (RLC)
transmission between a transmitter and a receiver with an Automatic
Repeat Request (ARQ) arrangement whereby polling of the receiver is
accomplished with reduced amount of redundantly transmitted data, such as
between an access node and terminal. Upon a polling event, such as
emptying of a transmission buffer of the transmitter, expiration of a
polling timer, or reaching a radio link control (RLC) protocol data units
(PDUs) count threshold, the transmitter sends a polling command to the
receiver. This polling command is smaller than any of the RLC PDUs by
resegmenting to a variably sized PDU sending a reduced amount of data.
With evolving communication standards tending toward larger PDUs, such as
in excess of a kilobyte for HSPA+ (High-Speed Packet Access Evolution)
and 3GPP LTE (Long Term Evolution), this inefficiency can be of
increasing impact.
