Abstract:
1. A communication system comprising a first communication device, a second communication device, and a third communication device, the first communication device configuring a cell, wherein the first communication device comprises: a notification unit configured to notify, to the second communication device, an allocation information indicating at least one subcarrier to be used for communication; a reception unit configured to receive, from the second communication device, a Discrete Fourier Transform-spread-OFDM (DFT-S-OFDM) signal; and a communication unit configured to communicate with the second communication device by using at least one first subcarrier(s) and at least one second subcarrier(s), which the at least one first subcarrier and the at least one second subcarrier are comprised of a plurality of consecutive subcarriers, wherein each of the at least one first subcarriers is used by the second communication device and the third communication device in a same time frame, the third communication device being in the cell, wherein each of the at least one second subcarriers is used by the second communication device, and is not used by the third communication device in a same time frame, and wherein the allocation information includes information on the at least one first subcarrier(s) and the at least one second subcarrier(s).
