- Especially in information routing with concurrent demand for limited capacity of channels there may be a need for a concept of intervention to balance between e.g. the needs of intelligible speech transmission and of sufficiently dynamic control commands. Any fixed allocation of resources will lead to a mismatch under special conditions of operations. (en)
- The cross layer approach transports feedback dynamically via the layer boundaries to enable the compensation for overload, latency or other mismatch of requirements and resources by any control input to another layer, but that layer directly affected by the detected deficiency. (en)
- For example, having knowledge of the current physical state will help a channel allocation scheme or automatic repeat request strategy at the MAC layer in optimizing tradeoffs and achieving throughput maximization. (en)
