Abstract
In a time slot in which a first base station for performing a multicast transmission executes the multicast transmission, a second base station which does not perform the multicast transmission does not perform a unicast data transmission. The time slot in which the first base station performs the multicast transmission is notified to the second base station from a multicast control apparatus for performing scheduling of the multicast transmission to the first base station. Information to receive the multicast transmission is notified from the second base station to a terminal connected to the second base station.
Claims14
A wireless communication system comprising:
- a first base station for performing a multicast transmission to a plurality of terminals;
- and
- a second base station which does not perform the multicast transmission,
- wherein on the basis of a time slot in which the first base station performs the multicast transmission, said second base station controls communication to the terminal which is executed by said second base station.
A wireless communication system comprising:
- a first base station for performing a multicast transmission to a plurality of terminals;
- and
- a second base station which does not perform the multicast transmission,
- wherein the second base station notifies the terminal connected to the second base station of said time slot in which the first base station performs the multicast transmission.
A second base station in which a range of communication with a terminal overlaps with a communication range of a first base station which performs a multicast transmission, comprising:
- an obtaining unit for obtaining information regarding a time slot in which said multicast transmission is performed;
- and
- a control unit for controlling the communication with said terminal in a time slot corresponding to said obtained time slot.
