Abstract
Rate adaptation is carried out using bit error rate (BER) to enable effective multimedia transmission. The BER can be estimated using signal strength in a MAC layer and modulation information (FIGS. 7-9), and can be compatibly used in different wireless networks by means of message standardization.
Claims10
An apparatus of receiving multimedia, the apparatus comprising:
- a message generator configured to generate a message including an indicator indicating a layer where a bit error rate is generated among a plurality of different layers including at least one of a physical (PHY) layer and an MAC (Media Access Control) layer,
- wherein the message generator is implemented in a processor.
An apparatus of transmitting multimedia, the apparatus comprising:
- a message receiver configured to receive a message including an indicator indicating a layer where a bit error rate is generated among a plurality of different layers including at least one of a physical (PHY) layer and an MAC (Media Access Control) layer.
An apparatus of estimating a channel condition using a bit error rate, the apparatus comprising:
- a BER generator configured to generate the bit error rate (BER) using side information among a plurality of different layers including at least one of a physical layer and an MAC layer;
- and
- a transmitter configured to include the bit error rate and an indicator indicating a layer where the generated bit error rate is generated in a message and to transmit the message to another layer,
- wherein the BER generator is implemented in a processor.
