Patent ID: 8670404

Claim:
A wireless communication method, comprising: transmitting, by a transmitter, frequency information for transmitting data to a multicast group and offset information indicating an offset amount of a timing at which the data is to be transmitted with respect to a predetermined periodic reference timing; transmitting, by the transmitter, the data to the multicast group using a frequency determined by the frequency information at a transmission timing determined by the offset information; receiving, by a receiver, the frequency information and the offset information transmitted by the transmitter; and receiving, by the receiver, data being transmitted to the multicast group based on the frequency information and the offset information, wherein a time interval between the predetermined periodic 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 when data transmission is to be performed.
