[Translate to englisch:] Hierarchical Radio Resource Allocation for Device to Device (D2D) Communication in LTE and 5G


Abstract

In order to provide low latencies at high reliability, a part of the radio resources need to be reserved for this traffic (semi-persistent scheduling). In case this traffic is event-based and sporadic, most of these reserved resources remain unused, resulting in a tremendous waste of resources which in turn decreases the overall network capacity.

Our approach allows a second user in vicinity to benefit and allocate these reserved, but otherwise unused resources.

In our hierarchical scheme, the base station grants resources to a highly latency and high reliability demanding communication semi-persistently (similar to the solution in LTE). In case this user does not need the granted resource, the resource is sub-granted to another user in its vicinity.


Background

In case this traffic is event-based and sporadic, most of these reserved resources remain unused, resulting in a tremendous waste of resources which in turn decreases the overall network capacity.
