Multi-Connectivity

How do we optimize communications for reliability rather than data rate by using multiple links?

Many new applications of wireless communication systems, such as autonomous driving, industrial robots and medical monitoring, require a very high reliability. It means that we have to be sure that the information is correctly transmitted with an extremely high probability. One well known method to increase the reliability and resilience of wireless communications systems is to provide multiple independent communication links, such that, if one or more of them fails, there is still a high probability that there will still be available resources that are good enough for communications at any given time.

This is called multi-connectivity, but the allocation of multiple communication links also increases the usage of radio resources, i.e., channels that could be otherwise used for new communications or by other users are blocked to provide redundancy.

At the BI we investigate methods that allow us to improve the efficiency of these methods, by adapting the amount of resources to the application requirements, channel conditions and traffic levels.
