RADIO COMMUNICATION UNIT, SEMICONDUCTOR INTEGRATED CIRCUIT FOR COMMUNICATION, AND COMMUNICATION SYSTEM

摘要

A radio communication unit performs packet communication like Bluetooth communication according to a specified protocol but has no packet retransmission function and is capable of synchronous communication of such a packet that the header has no area for the information indicative of the order of packet. The radio communication unit is provided with a function for judging presence/absence of a reception packet at a specified interval and informing the loss (missing) of a packet to a host controller when a reception packet is not present.
