Radio communication system, radio communication device, and radio communication method
First Claim
1. A radio communication system for transmitting voice or music data, comprising:
- a data supplying source device for supplying the voice or music data, the data supplying source device having a reflector for transmitting a reflected wave signal obtained by modulating a received radio wave based on the data to be transmitted; and
a data supply destination device for receiving the voice or music data, the data supply destination device having a reflected wave reader for transmitting an unmodulated carrier and for reading a reflected wave signal resulting from modulation of the unmodulated carrier;
wherein the voice or music data is transmitted in packets to be reproduced on said data supply destination device by reflected wave transmission between the data supplying source device and the data supply destination device; and
wherein when a data type indicator in the data packet indicates that the data type is voice or music the data supply destination device begins a process of decoding a part of the voice or music data packet without waiting for the voice or music data packet to be operated on by a process of a communication protocol that is at a higher protocol level than the decoding process,wherein when the data type indicator in the data packet indicates that the data type is a content that the data supply destination device is not ready for decoding, the data supply destination device discards the data packet including the content that the data supply destination device is not ready for decoding without waiting transfer to a process of the communication protocol that is at a higher protocol level than the decoding process, andwherein when the data type indicator in the data packet indicates that the data type is command a notification thereof is made to a higher protocol level than the decoding process.

Abstract
A radio communication system for transmitting voice or music data includes a data supplying source device for supplying the voice or music data, the data supplying source device having a reflector for transmitting a reflected wave signal obtained by modulating a received radio wave based on the data to be transmitted; and a data supply destination device for receiving the voice or music data, the data supply destination device having a reflected wave reader for transmitting an unmodulated carrier and for reading a reflected wave signal resulting from modulation of the unmodulated carrier. The voice or music data is transmitted by reflected wave transmission between the data supplying source device and the data supply destination device.

24. A radio communication device for supplying voice or music data by reflected wave transmission, said radio communication device comprising:
-
storing means for capturing external voice or music data and for storing the captured voice or music data; reproducing means for reproducing the stored voice or music data; a reflector for transmitting a reflected wave signal obtained by modulating a received radio wave based on the data to be transmitted in packets; and communication controlling means for controlling an operation of transmitting the reflected wave signal using the reflector; wherein the voice or music data stored by the storing means is transmitted in packets as the reflected wave signal using the reflector; and wherein when a data type indicator in the data packet indicates that the data type is voice or music the reproducing means begins a process of decoding a part of the voice or music data packet without waiting for a process on the voice or music data packet to be operated on by a process of a communication protocol that is at a higher protocol level than the decoding process, wherein when the data type indicator in the data packet indicates that the data type is a content that the data supply destination device is not ready for decoding, the data supply destination device discards the data packet including the content that the data supply destination device is not ready for decoding without waiting transfer to a process of the communication protocol that is at a higher protocol level than the decoding process, and wherein when the data type indicator in the data packet indicates that the data type is command a notification thereof is made to a higher protocol level than the decoding process. - View Dependent Claims (25)

26. A radio communication method for supplying voice or music data by reflected wave transmission, said radio communication method comprising:
-
capturing external voice or music data and storing the captured voice or music data; reproducing the stored voice or music data; and transmitting in packets a reflected wave signal obtained by modulating a received radio wave based on the stored voice or music data; and when a data type indicator in the data packet indicates that the data type is voice or music, decoding a part of the voice or music data packet without waiting for the voice or music data packet to be operated on by a process of a communication protocol that is at a higher protocol level than the decoding process, when the data type indicator in the data packet indicates that the data type is a content that the data supply destination device is not ready for decoding, the data supply destination device discards the data packet including the content that the data supply destination device is not ready for decoding not decodable without waiting transfer to a process of the communication protocol that is at a higher protocol level than the decoding process, and when the data type indicator in the data packet indicates that the data type is command, notifying a higher protocol level than the decoding process.
