The receiver receives a multicast signal. The transmitter transmits the multicast signal to a mobile station apparatus. The determiner determines, in accordance with a status of communication with the mobile station apparatus, whether the transmission of the multicast signal is needed. The instruction sender transmits, in accordance with a result of the determination, an instruction signal indicating whether to join a group of destinations of the multicast signal to a distribution apparatus for distributing the multicast signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Base station apparatus and method for delivering multicast signal","description":"A base station apparatus includes a receiver, a transmitter, a determiner, and an instruction sender.
