Abstract
The invention relates to an apparatus comprising: at least one processor and at least one memory including a computer program code, the at at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: transmit an indication of device-to-device communications between a plurality of user devices to an access node; receive an information on a configuration for device-to-device control information signaling via the access node, and transmit the device-to-device control signalling according to the informed configuration via the access node.
Claims17
An apparatus comprising:
- at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- obtain an indication of device-to-device communication between a plurality of user devices;
- obtain information on an operation mode of the plurality of user devices;
- if the operation mode of the plurality of user devices is a half duplex mode:
- configure a cellular uplink control channel for a first user device of the plurality of user devices and a cellular downlink control channel for a second user device of the plurality of user devices for device-to-device control information as a pair of control channels;
- if the operation mode of the plurality of user devices is a full duplex mode:
- configure a cellular shared control channel and/or reallocate an existing cellular uplink control channel and/or an existing cellular downlink control channel for device-to-device control information;
- if the operation mode of at least one of the plurality of user devices is a half duplex mode and of at least one other of the plurality of user devices is a full duplex mode:
- configure for the at least one of the plurality of user devices in the half duplex mode a cellular uplink control channel and/or a cellular downlink control channel as a pair of control channels and configure a cellular shared control channel and/or reallocate an existing cellular uplink control channel and/or an existing cellular downlink control channel for the at least one other of the plurality of user devices in the full duplex mode, the cellular uplink control channel, the cellular downlink control channel and the cellular shared control channel being for device-to-device control information, and
- inform the configuration or the reallocation to at least one of the plurality of user devices.
