Abstract
A method, system and apparatus are disclosed. A network node configured to communicate with a wireless device is provided. The network node configured to, and/or comprising a radio interface and/or comprising processing circuitry configured to receive a unicast request message from a wireless device where the unicast request message includes information associated with a request for a unicast connection, and determine whether to permit establishment of the requested unicast connection based at least in part on the information in the unicast request message.
Claims21
A network node for allocating a resource pool for use by a wireless device in device to device communications, the resource pool being one of a plurality of resource pools, each resource pool comprising one or more time and frequency resource, the network node comprising processing circuitry configured to:
- obtain one or more properties associated with one of a unicast, multicast and broadcast connection, the obtained one or more properties being received from the wireless device in a request for configuration of the one of the unicast, multicast and broadcast connection, the request message indicating a preferred casting type, a casting type being one of unicast, multicast and broadcast;
- determine whether the requested configuration can be established;
- and
- allocate a resource pool per wireless device for the requested configuration based on the one or more properties and for the preferred casting type.
A wireless device for using a resource pool for device to device communication, the resource pool being one of a plurality of resource pools, each resource pool corresponding to time and frequency resources, the wireless device comprising processing circuitry configured to:
- cause transmission of a request message that indicates one or more properties for configuration of one of a unicast, multicast and broadcast connection and indicates a preferred casting type, a casting type is one of unicast, multicast and broadcast;
- and
- receive an indication of an allocated resource pool, the resource pool being allocated to establish a unicast, multicast or broadcast connection for the wireless device and the resource pool being allocated based on one or more properties associated with the one of the unicast, multicast and broadcast connection, and the allocated resource pool being for the preferred casting type.
A method implemented by a network node for allocating a resource pool for use by a wireless device in device to device communications, the resource pool being one of a plurality of resource pools, each resource pool comprising one or more time and frequency resource, the method comprising:
- obtaining one or more properties associated with one of a unicast, multicast and broadcast connection, the obtained one or more properties being received from the wireless device in a request for configuration of the one of the unicast, multicast and broadcast connection, the request message indicating a preferred casting type, a casting type being one of unicast, multicast and broadcast;
- determining whether the requested configuration can be established;
- and
- allocating a resource pool per wireless device for the requested configuration based on the one or more properties and for the preferred casting type.
