“…The self-coordinator module receives as input the actions selected by each subMDP, and based on that, the possible situations to face are the following: If the actions are the same, the coordinator just executes the action, otherwise, the conflict is solved by mixed strategies through the reward matrix depicted inside the coordination box in Figure 4, where A, a, are the rewards of subMDP 1 and subMDP 2 , respectively, when executing for both subMDP α; B, b, are the rewards of subMDP 1 and subMDP 2 , respectively, when executing action α for subMDP 2 and action β for subMDP 1 ; C, c, are the rewards of subMDP 1 and subMDP 2 , respectively, when executing Hence, each player is not actually choosing α, β directly, but choosing a probability with which a player will play α. A given number p means that player 1 will play α with probability p and β with probability 1 − p. Similar considerations can be done for player 2.…”

“…Let subMDP 1 In this section, we provide an example about how the proposed functional architecture can be used to deal with the conflicts generated by the concurrent execution of multiple SON functions. The objective of this section is to show that the proposed approach is general enough to model all the SON functions and their derived conflicts.…”

“…After detection, compensation from other nodes can occur through relay assisted handover for ongoing calls, adjustments of neighboring cell sizes via power compensation or antenna tilt. In [1], the authors not only propose a cell outage management description but also describe compensation schemes. These steps of monitoring and detection, then compensation of nodes failures are comprised under the self-healing functions of future cellular networks.…”

“…With increasing scale of networks, automatic detection and compensation of cell outage has become a necessity, and, it has been included in recent 3GPP releases [6]. Therefore, the SON paradigm aims to replace these manual tasks with an autonomous process referred to cell outage management (COM) [7]- [12]. COM can be further subdivided into cell outage detection (COD) and cell outage compensation (COC).…”
