COMMUNICATION DEVICE AND COMMUNICATION METHOD

摘要

A BTS (100) comprises: a MAC-hs processing unit (120) that determines the priority level of a communication that is to be executed in response to an accepted communication request; and a HARQ process control unit (121) that, if it is determined that the foregoing priority level is equal to or higher than a predetermined priority level, allocates, as a priority-given communication, the communication that is to be executed in response to the communication request to one of a plurality of HARQ processes, which are a unit of processing automatic retransmission requests, on a priority basis over the other communications.  When all of the HARQ processes are occupied by other communications, the HARQ process control unit (121) discards some of packets stored in a HARQ buffer (123) in accordance with the number of HARQ processes required for the execution of the priority-given communications.
