Abstract

A mobile communication device (110) with a wireless module (111) and a controller module (112) is provided for improving data throughput by dynamically adjusting a window size of the TCP/IP communication protocol layer. The wireless module (111) performs wireless transceiving to and from a service network (120). The controller module (112) measures a link quality of the service network (120) associated with the physical layer (e.g. channel quality indicator-CQI) via the wireless module (111), and determines a number of transmission layers supported for spatial multiplexing (MIMO) associated with the physical layer (e.g. rank indcator-RI) . The controller module (112) then adjusts the TCP/IP window associated with the transport/network layer according to the link quality and the number of transmission layers associated with the physical layer.
