PROBLEM TO BE SOLVED: To provide a communication system which enhances efficiency of a carrier aggregation function, and to provide a communication device, a partner communication device and a communication control method.SOLUTION: A communication system 100 comprises: a communication device 101; and partner communication device 103 performing wireless communication with the communication device 101 by using a carrier aggregation function. The communication device 101 transmits a plurality of wireless signals in the frequency bands 105A, 105B added with reference information indicating a reference time, and corrects the transmission timing of wireless signal in the frequency bands 105A, 105B based on the information indicating a reception timing difference of a plurality of wireless signals upon receiving that information. The partner communication device 103 determines the reception timing difference of a plurality of wireless signals, from the reception time and the reference time of reference information of a plurality of wireless signals, and transmits the information indicating the reception timing difference. |
