The next KE Hub online Triage Workshop will be presented by BT.
Convex and quasiconvex optimization in cellular radio networks
Certain optimization problems in cellular radio networks (such as are used in 4G and 5G) give rise to non-convex problems, well-known to be difficult to solve with exact algorithms. However, some problems of interest are quasiconvex, and these can typically be solved by reduction to a sequence of convex subproblems. But though such methods are theoretically exact, in practice they often show instabilities due to the ill-conditioning or poor scaling of the sub-problems. This project thus aims to improve on existing solution techniques for quasiconvex optimization problems. Complicated nonlinear constraints also have to be taken into consideration. The particular application of current interest is reducing energy consumption in network operations, while maintaining a good service to users of the network.
Academic mathematical scientists from KE Hub partner university departments are invited to take part in these workshops. If you would like to attend, please contact your local KE Champion to receive the meeting link or get in touch with the organisers, Lauren Hyndman and Diwei Zhou.
KE Hub Triage Workshops are informal discussion sessions where one B.I.G. Partner presents a challenge they are currently facing, with the aim of determining:
- What, if any, mathematical sciences approaches can be used to address the challenge?
- Who from the mathematical sciences community would like to take on the challenge?
- What mechanisms are most appropriate for driving the challenge forward?
The purpose of these workshops is to allow the B.I.G. Partner to engage directly with academic mathematical scientists to probe the scientific content of their proposed challenge. The environment is relaxed and interactive, and we encourage questions, clarifications and discussions throughout. You can find information on all upcoming and past workshops here.
