1. A base station, comprising:
- an acquisition unit configured to acquire from a terminal device a plurality of packets to be transmitted to a mobile station;
a priority calculation unit configured to calculate a priority of transmission of one packet of said plurality of packets relative to at least another packet of said plurality of packets;
a weight processing unit configured to conduct weighting on the priority of the one packet calculated by the priority calculation unit to produce a weighted priority;
a channel control unit configured to assign a channel for transmission to the one packet based on the weighted priority; and
a transmission unit configured to transmit the one packet to the mobile station on the channel assigned by the channel control unit, whereinthe weight processing unit conducts weighting on the priority based on a reception state of the mobile station, wherein the reception state is judged based on a status of a transmission path formed between the transmission unit and the mobile station, and the priority calculation unit calculates the priority based on whether the one packet is a retransmission packet transmitted to the mobile station again by the transmission unit, a status of a transmission path formed between the transmission unit and the mobile station, and quality of service of the one packet.

Abstract
A base station includes an acquisition unit for acquiring a packet transmitted from a terminal device to a mobile station, a priority calculation unit for calculating priority of transmission of the packet acquired by the acquisition unit to the mobile station, a weight processing unit for conducting weighting on the priority of the packet calculated by the priority calculation unit, a channel control unit for assigning a channel for transmission of the packet to the mobile station, to the packet based on the priority of the packet weighted by the weight processing unit, and a transmission unit for transmitting the packet to the mobile station on the channel assigned by the channel control unit.

10. A communication method using a base station, comprising:
-
acquiring from a terminal device a plurality of packets to be transmitted to a mobile station; calculating a priority of transmission of one packet of said plurality of packets relative to at least another packet of said plurality of packets; conducting weighting on the calculated priority of the one packet to produce a weighted priority; assigning a channel for transmission to the packet based on the weighted priority of the one packet; and transmitting from a transmission unit the one packet to the mobile station on the assigned channel, wherein the conducting weighting on the priority is based on a reception state of the mobile station, wherein the reception state is judged based on a status of a transmission path formed between the transmission unit and the mobile station, and the calculating the priority of transmission is based on whether the one packet is a retransmission packet transmitted to the mobile station again by the transmission unit, a status of a transmission path formed between the transmission unit and the mobile station, and quality of service of the one packet. - View Dependent Claims (11, 12, 13, 14, 15)
