Signal transmission method and apparatus in wireless communication system

A signal transmission apparatus in a wireless communication system using transmission control protocol/internet protocol (TCP/IP), the signal transmission apparatus comprising:

• a transceiver coupled to at least one antenna configured to perform wireless communication;
• a packet signal generator configured to generate packet signals to be transmitted through the transceiver;
• a protocol stack queue configured to store the generated packet signals;
• and
• a controller configured to divide the generated packet signals into a plurality of control signals and multiple data based on a payload size of each of the packet signals, store a first control signal as a latest generated control signal among the plurality of control signals in the protocol stack queue by inputting the first control signal to a head of the protocol stack queue, store the multiple data in the protocol stack queue by inputting the multiple data to a tail of the protocol stack queue according to an order of generation, and control the transceiver to transmit the first control signal and the multiple data in order stored in a location closest to the head of the protocol stack queue such that the first control signal is transmitted before the multiple data is transmitted.

A wireless communication system configured for transmission control protocol/internet protocol (TCP/IP) communication, the wireless communication system comprising:

• at least two nodes, wherein each of the at least two nodes comprises:
• a transceiver configured to perform wireless communication;
• a packet signal generator configured to generate packet signals to be transmitted through the transceiver;
• a stack queue memory configured to store the generated packet signals;
• and
• a controller configured to divide the generated packet signals into a plurality of control signals and multiple data based on a payload size of each of the packet signals, store a first control signal as a latest generated control signal among the plurality of control signals in the stack queue memory by inputting the first control signal to a head of the stack queue memory, store the multiple data in the stack queue memory by inputting the multiple data to a tail of the stack queue memory according to an order of generation, and to control the transceiver to transmit the first control signal and the multiple data in order stored in a location closest to the head of the stack queue memory such that the first control signal is transmitted before the multiple data is transmitted.
