Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we compare QoS and QoE of reliable transmission methods using retransmission and that using AL-FEC on audiovisual Groupcast over wireless LANs.
We consider audiovisual groupcast with priority control by EDCA from a single access point to multiple wireless terminals.
We compare four transmission methods: groupcast，GCR Unsolicited Retry，GCR Block Ack and groupcast with AL-FEC.
We perform a computer simulation under various network conditions to assess application-level QoS and evalute QoE by a subjectibe experiment.
As a result, we find that selecting the appropriate transmission method for the network conditions can enhance QoE.
