Enhancing Cellular Coverage Quality by Virtual Access Point and Wireless Power Transfer

Table 1

The game scenarios in our work.

Scenario	Actor	Strategy	Payoff
ETR game	ETRs	Each player hopes to find the optimal charging power offered to its associating VAP to maximize its individual profit.	The utility of any player is computed by formula (6).
VAP game	VAPs	Each player hopes to find the optimal forwarding power to offer data forwarding service for its associating UEs to maximize its individual profit.	The utility of any player is computed by formula (13).
Stackelberg game	MBS ETRs VAPs	The MBS hopes to obtain the maximum forwarding traffic from the VAPs but just wants to pay the minimum price of energy.	The utility of the MBS is computed by formula (17).
