Abstract
A method for servicing a data communication in a cellular wireless communication system adjusts the ARQ operations of an upper protocol layer to compensate for fluctuating bandwidth provided by the cellular wireless communication system. In one embodiment, a Retransmission Time Out (RTO) of the ARQ operations of the upper protocol layer, e.g., Transmission Control Protocol layer, is adjusted to compensate for the fluctuating bandwidth provided by the cellular wireless communication system. Radio resources include a fundamental channel (FCH) and a supplemental channel (SCH). The FCH is allocated for the duration of the data communication while the SCH is periodically allocated and released. The RTO is adjusted so that unnecessary retransmissions are precluded when the SCH is released and also so that retransmissions of lost data segments occur.
