Abstract

A wireless communication system, method, program, and/or circuitry which includes at least a base station device and a terminal device. The base station device is configured to transmit information indicating a slot for transmitting data by the transmission device. The terminal device is configured to decode the received information using a first communication scheme and transmit data to be allocated to the slot using a second communication scheme to an another terminal device, where the first communication scheme is a different scheme than the second communication scheme.

         5 . The transmission method according to  claim 1 , wherein
 the slot is an allocation unit which is composed of one or more frequency sub-channels and one or more time sub-channels.   
     
     
         6 . A terminal device comprising:
 a receive unit configured to receive information indicating a slot to be allocated by a base station device;   a decoding unit configured to decode the received information using a first communication scheme; and   a RF unit configured to transmit, to an another terminal device, data to be allocated to the slot using a second communication scheme, wherein   the first communication scheme is a different scheme than the second communication scheme.   
     
     
         7 . A wireless communication system comprising:
 a base station device; and   a terminal device, wherein   the base station device is configured to:
 transmit information indicating a slot for transmitting data by the transmission device, and 
   the terminal device is configured to:
