Title:
無線通信システム、再送パラメータ決定装置、および再送パラメータ通知方法
Document Type and Number:
Japanese Patent JP6991784
Kind Code:
B2
Abstract:
A wireless communication system, in which a redundancy bit is transmitted from a first communication device (10) to a second communication device (20) when the second communication device fails to decode the encoded bits, includes a selector (27a), a transmission data length calculator (27b), a transmission latency calculator (27c), and a retransmission parameter generator (27d) . The selector selects communication patterns that respectively satisfy a requested quality. The transmission data length calculator calculates, for each of the selected communication patterns, a transmission data length that indicates a length of the redundancy bit. The transmission latency calculator calculates, for each of the selected communication patterns, a transmission latency between the first communication device and the second communication device based on the calculated transmission data length. The retransmission parameter generator generates a retransmission parameter corresponding to a communication pattern with lowest transmission latency among the selected communication patterns. The first communication device transmits the redundancy bit according to the retransmission parameter, and the second communication device decodes the encoded bits by using the redundancy bit according to the retransmission parameter.
