Abstract:
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.
