One efficient technique to combat intercell interference is via exploiting coordination among multiple base stations, which is known as multicell processing or simply base station coordination.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.
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.
Is base station scheduling NP-hard?To this aim, we show that finding the optimal base station scheduling is NP-hard, and formulate the BASICS (BAse Station Inter-Cell Schedul-ing) algorithm, a novel heuristic to approximate the optimal solution at low complexity cost.
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.
Do all base stations use the same frequency?Unless otherwise specified, all base stations use the same frequencies. Users associate to the base station from which they receive the strongest signal, and transmission rates are selected, in each subframe, according to the Signal-plus-Noise Interference Ratio (SINR), see Table 5.1. The SINR for a certain user u = 1 : : : k is defined as follows:.
Can base station scheduling reduce interference?Interestingly, they do not identify base station scheduling as a possible tool to reduce interference, and limit their discussion to beamform-ing, coding and decoding techniques, opportunistic spectrum access, interference cancella-tion, power control and (fractional) frequency reu

In this paper, we propose a coordinated scheduling approach across multiple base stations to provide diversity for mobile terminals positioned within the overlapping coverage areas.
