Abstract
In order to facilitate cellular device-to-device communication, a cross-layer optimization functionality, utilizing for example monitoring capabilities of a MAC layer entity, and adjustment capabilities of an application control entity, is introduced.
Claims19
A method comprising
- detecting a device-to-device direct communication and between a first user equipment and a second user equipment;
- and
- triggering, responsive to receiving in the first user equipment an indication from a base station, a cross-layer optimization between an application control entity and one or more link layer entities for the device-to-device direct communication.

An apparatus comprising at least one processor, and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least:
- detect a device-to-device direct communication between a first user equipment and a second user equipment;
- and
- trigger, responsive to receiving in the first user equipment an indication from a base station, a cross-layer optimization between an application control entity and one or more link layer entities for the device-to-device direct communication.
A non-transitory computer-readable medium including computer code which when executed by at least one processor provides operations comprising:
- detecting a device-to-device direct communication between a first user equipment and a second user equipment;
- and
- triggering, responsive to receiving in the first user equipment an indication from a base station, a cross-layer optimization between an application control entity and one or more link layer entities for the device-to-device direct communication.
