<P>PROBLEM TO BE SOLVED: To suppress increase of delay time in WCDMA communication in serial communication between RF-LSI and DBB-LSI in a wireless communication device performing multimode communication including LTE communication and the WCDMA communication. <P>SOLUTION: A wireless communication device 100 having LSIs for wireless communication which deal with at least a WCDMA communication mode and a LTE communication mode, where RF-LSI 102 and DBB-LSI 103 are connected by a serial interface, comprises: a wireless transmission part 121 and a wireless reception part 122 which transmit and receive packets in the RF-LSI 102; and an RF-LSI serial communication control part 123 and a DBB-LSI serial communication control part 131 which stop retransmission processing of the packets when the wireless communication device 100 uses the WCDMA communication mode, and perform the retransmission processing of the packets when the wireless communication device 100 uses the LTE communication mode. <P>COPYRIGHT: (C)2012,JPO&INPIT |
