Abstract: The power requirements of user equipments (UEs) are expected to increase as their capabilities increase. Some power saving methods have previously been proposed, but are limited by the radio resource control (RRC) protocol and do not address the power consumption associated with having to transition between different RRC states.

Within that single RRC state, there are different modes of operation, e.g. a default low power operation mode and an enhanced power operation mode. In some embodiments, the UE switches from the default operation mode to the enhanced operation mode on an on-demand basis (e.g. based on the communication capability required by the UE), and then returns back to the default operation mode.

Abstract: Batched network coding (BNC) is a low-complexity solution to network transmission in multi-hop networks with packet loss that divides data to be transmitted into multiple packets and pads the data when necessary. However, an inappropriate choice of packet size leads to a significant overhead.

The disclosed techniques for performing dynamic optimization of transmissions also reduce computational complexity, enabling use case deployments in which nodes having reduced computational resources and power requirements are utilized while maintaining improved performance of the network (e.g., in terms of throughput, etc.).
