Abstract
A method in a radio network node for handling a Device-to-Device, D2D, communication is provided. The D2D communication is wireless, and the radio network node is comprised in a wireless communication system. After receiving (201) from a first user equipment, an indication of resources that are currently available in the first user equipment for D2D communication, the radio network node identifies (202) whether or not the first user equipment currently has capacity for a D2D communication based on the received indication. The resources relates to hardware resources, to combined hardware resources and radio resources, or to combined software resources, hardware resources and radio resources.
Claims18
A method in a second user equipment for handling a Device-to-Device, D2D, communication, which D2D communication is wireless, and which second user equipment is comprised in a wireless communication system, the method comprising:
- receiving over a cellular link via a radio network node serving a first user equipment, an indication of resources of the first user equipment, the indication of resources comprising:
- an indication of current memory resource usage or buffer status of first user equipment in maintaining a current cellular communication with the radio network node over the cellular link and an indication of memory or buffer resources that are currently available in the first user equipment for D2D communication over D2D link, which memory or buffer resources relates to hardware resources, to combined hardware resources and radio resources, or to combined software resources, hardware resources and radio resources,
- identifying, based at least in part on the received indication, whether or not the first user equipment currently has capacity for simultaneously maintaining D2D communication with the second user equipment over the D2D link and a cellular communication with the radio network node over the cellular link.
A second user equipment for handling a Device-to-Device, D2D, communication, which D2D communication is wireless, the second user equipment comprising:
- a receiving port configured to receive over a cellular link via a radio network node serving a first user equipment, an indication of resources of the first user equipment, the indication of resources comprising:
- an indication of current memory resource usage or buffer status of first user equipment in maintaining a current cellular communication with the radio network node over the cellular link and an indication of memory or buffer resources that are currently available in the first user equipment for D2D communication over a D2D link, which memory or buffer resources relates to hardware resources, to combined hardware resources and radio resources, or to combined software resources, hardware resources and radio resources,
- an identifying unit configured to identify, based at least in part on the received indication, whether or not the first user equipment currently has capacity for simultaneously maintaining D2D communication with the second user equipment over the D2D link and a cellular communication with the radio network node over the cellular link.
