Base station site coordination process

Can base station downlink activities mitigate inter-cell interference?

Differently from the work available in the literature, we tackle the problem of inter-cell interference mitigation from the perspective of scheduling base stations rather than users. In particular, we propose to coordinate base station downlink activities in order to mitigate the interference caused to neighboring cells.

What happens when all base stations are allocated?

When all base stations are allocated, the algorithm ends returning the complete base station scheduling plan. One of the key parameters upon which BASICS relies is the SINR threshold Th, i.e., the minimum SINR guaranteed to each scheduled user in the system.

How does a base station re-check a subnetwork?

Once base stations are sorted, the algorithm removes the most interfering base station from the set of candidate base stations (lines 12-13). The algorithm then re-checks SINR constraints for the subnetwork obtained by removing the most interfering base station and all its users from the original network.

What is a base station scheduling problem?

base station scheduling problem to decide whether a base station is allowed to transmit to any of its users in a given sub-frame, without causing excessive interference to any of the users of other scheduled base stations.
