Playing Radio Resource Management Games in Dense Wireless 5G Networks

Table 1

Comparison of strategies.

	Strategy name	ID	Payoff definition	Information exchanged
1	Nash equilibrium	NE	Cell rate achieved by base station: see (6)	None
2	Correlated equilibrium		It is as for NE, but the cost of rate reduction observed by other players is considered; see (9)	Channel information or payoff table
3	CE reduced		As for number 2, but reduced backhaul traffic, only the chosen payoff is updated	Payoff value for selected strategy
4	Satisfaction equilibrium binary		Wastage of redundantly assigned resources is minimized; satisfaction correspondence is calculated as (20)	None
5	Satisfaction equilibrium sigmoid		It is as for 4, but satisfaction correspondence is calculated as (21)	Satisfaction table
6	Energy efficiency		Selected strategies have been modified to include energy efficiency in the payoff definition as in (24) in Section 3.3	As in 2–5
7	Quantization		16-level quantization of the information exchanged among players is applied, Section 3.4	As in 2–5, but with reduced binary representation to 4 bits
8	Energy efficiency and quantization		Mixed strategies utilize energy efficiency increasing payoff definition and quantization, Section 3.5	As in 7
