Resource information transmission for multicasting in a wireless network

摘要

A wireless communication apparatus comprising:
a generating unit that generates frequency information for transmitting data to a multicast group and offset information indicating an offset amount of a timing at which the data are to be transmitted with respect to a predetermined periodic reference timing; and
a transmission unit that transmits the frequency information and the offset information generated by the generating unit and transmits the data to the multicast group using a frequency determined by the frequency information at a transmission timing determined by the offset information;
wherein a time interval between the predetermined reference timing and the transmission timing of the data is set to differing time lengths depending on the offset amount indicated by the offset information; and
the frequency information and the offset information are transmitted prior to transmission of the data each time the data transmission is to be performed.
