COMMUNICATION APPARATUS, COMMUNICATION METHOD, COMMUNICATION PROGRAM, RECORDING MEDIUM, MOBILE STATION, BASE STATION, AND COMMUNICATION SYSTEM

摘要

A communication apparatus, a communication method, a communication program, a recording medium, a mobile station, a base station, and a communication system capable of guaranteeing communication quality. A packet judgment block (101) divides packets of different communication qualities in accordance with additional information added to the packets into three buffer groups: a group for real time RT, a group for quasi-real time QRT, and a group for non-real time NRT for each of the communication qualities, and the packets are stored in accordance with the empty state of each of the buffers. At every time slot, the three buffer groups are circulated by a boundary allocation controller (105) so as to check whether a stored packet is present, so that stored packets are successively fetched from a buffer group having a stored packet and at every time slot, the code of the packet fetched by the boundary allocation controller (105) is multiplexed by a CDMA multiplex processor (111), thereby obtaining a transmission output ot.
