Abstract
A wireless communications device is configured to act as a remote node of a wireless access network by selecting, when the wireless communications device is in an idle mode in which it has not established a connection to the wireless communications network, an infrastructure equipment forming part of the radio access network of the wireless communications network to provide a network interface with a core network part of the wireless communications network via the selected infrastructure equipment.
Claims20
A wireless communications device for acting as a relay node of a wireless communications network, the wireless communications device comprising:
- circuitry configured to
- select, when the wireless communications device is in a radio resource control (RRC) idle mode, an infrastructure equipment forming part of the wireless communications network to provide a network interface with a core network part of the wireless communications network via the selected infrastructure equipment;
- transmit uplink radio signals to the selected infrastructure equipment, the uplink radio signals representing uplink data received from one or more communications devices for transmission to the core network, when the wireless communications device is operating as the relay node;
- and
- receive downlink radio signals from the selected infrastructure equipment, the downlink radio signals representing downlink data for transmission to one or more communications devices received from the core network part of the wireless communications network, when the wireless communications device is operating as the relay node, wherein
- the circuitry is configured to select the infrastructure equipment from a plurality of infrastructure equipment to provide the network interface in response to receiving, from the selected infrastructure equipment, an indication that the selected infrastructure equipment has a capability to form the network interface for the wireless communications device, and
- the circuitry is configured to select the infrastructure equipment in a case that the wireless communications device receives an indication in system information that the selected infrastructure equipment is reserved for operator use.
A method of operating a wireless communications device to act as a relay node of a wireless communications network, the method comprising:
- selecting, when the wireless communications device is in a radio resource control (RRC) idle mode, an infrastructure equipment forming part of the wireless communications network to provide a network interface with a core network part of the wireless communications network via the selected infrastructure equipment;
- transmitting uplink radio signals to the selected infrastructure equipment, the uplink radio signals representing uplink data received from one or more communications devices for transmission to the core network, when the wireless communications device is operating as the relay node;
- and
- receiving downlink radio signals from the selected infrastructure equipment, the downlink radio signals representing downlink data for transmission to one or more communications devices received from the core network part of the wireless communications network, when the wireless communications device is operating as the relay node, wherein
- the selecting includes selecting the infrastructure equipment from a plurality of infrastructure equipment to provide the network interface in response to receiving, from the selected infrastructure equipment, an indication that the selected infrastructure equipment has a capability to form the network interface for the wireless communications device, and selecting the infrastructure equipment in a case that the wireless communications device receives an indication in system information that the selected infrastructure equipment is reserved for operator use.
A wireless communications device for acting as a relay node of a wireless communications network, the wireless communications device comprising:
- circuitry configured to
- select, when the wireless communications device is in a radio resource control (RRC) idle mode, an infrastructure equipment forming part of the wireless communications network to provide a network interface with a core network part of the wireless communications network in response to receiving, from the selected infrastructure equipment, an indication that the selected infrastructure equipment has a capability to form the network interface for the wireless communications device, and in a case that the wireless communications device receives an indication in system information that the selected infrastructure equipment is reserved for operator use;
- and
- transmitting and receiving uplink radio signals and downlink radio signals to and from the selected infrastructure equipment when the wireless communications device is operating as the relay node.
