Abstract
Provided are apparatus and method for transmitting and receiving data for a wireless communication system. The method includes generating a first aggregation packet by controlling the number of preambles or by controlling a size of a packet according to a channel state of a channel formed to at least one reception terminal or according to a state of the reception terminal, and transmitting the first aggregation packet to the reception terminal.
Claims19
A method for transmitting data for a wireless communication system, comprising:
- transmitting a second aggregation packet to a reception terminal;
- receiving error information for the second aggregation packet from the reception terminal;
- generating a first aggregation packet by controlling the number of preambles or by controlling a size of a packet according to a channel state of a channel formed to at least one reception terminal or according to a state of the reception terminal;
- and
- transmitting the first aggregation packet to the reception terminal,
- wherein the first aggregation packet is generated according to error information indicating the channel state and the state of the reception terminal.
A method for transmitting data for a wireless communication system, comprising:
- transmitting a second aggregation packet to a reception terminal;
- receiving error information for the second aggregation packet from the reception terminal;
- generating a first aggregation packet;
- and
- transmitting the first aggregation packet by controlling a data transmit rate according to a channel state of a channel formed to at least one reception terminal and a state of the reception terminal,
- wherein the data transmit rate of the first aggregation packet is controlled according to the error information indicating the channel state and the state of the reception terminal.
An apparatus for transmitting data for a wireless communication system, comprising:
- a data processor configured to generate a first aggregation packet by controlling the number of preambles or by controlling a size of packet according to a channel state of a channel to at least one reception terminal or according to a state of the reception terminal;
