Abstract
A communication system includes: a first base station that operates as a donor for integrated access and backhaul, the first base station including a central unit and a distributed unit; and one or more second base stations that operate as nodes of the integrated access and backhaul, and in a case where multicast transmission of data is performed from the first base station to a communication terminal, the central unit performs a configuration for the multicast transmission on the distributed unit and the one or more second base stations.
Claims18
A communication system comprising:
- a first base station to operate as a donor for integrated access and backhaul, the first base station including a central unit and a distributed unit;
- and
- one or more second base stations to operate as nodes of the integrated access and the backhaul, wherein
- in a case where multicast transmission of data is performed from the first base station to a communication terminal,
- the central unit performs a configuration for the multicast transmission on the distributed unit and the one or more second base stations.
A communication system comprising:
- a base station;
- a first communication terminal connected to the base station;
- and
- a second communication terminal to perform, between the first communication terminal and the second communication terminal, terminal-to-terminal communication in which communication terminals directly communicate with each other, wherein
- in a case where the base station communicates with the second communication terminal via the first communication terminal, the base station performs scheduling for communication between the base station and the first communication terminal and scheduling for communication between the first communication terminal and the second communication terminal.
A base station to operate as a donor for integrated access and backhaul, the base station including a central unit and a distributed unit, wherein
- in a case where multicast transmission of data is performed to a communication terminal,
- the central unit performs a configuration for the multicast transmission on the distributed unit and the base station that operates as a node of the integrated access and the backhaul.
A base station comprising a communication system together with a plurality of communication terminals supporting terminal-to-terminal communication in which communication terminals directly communicate with each other, wherein
- in a case where the base station communicates with a second communication terminal via a first communication terminal, the base station performs scheduling for communication between the base station and the first communication terminal and scheduling for communication between the first communication terminal and the second communication terminal.
