Abstract
A fundamental problem for dynamic network planning is how many BSs can be turned off regarding traffic load variations [1]. In this section, we study the problem in a regular single-tier network providing time-varying multi-class services [2]. We optimize the density of active BSs under a tractable regularly sleeping scheme, aiming at minimizing average network power consumption while satisfying the quality of service requirements in terms of blocking probability.

Notes
- 1.
The analysis can be also applied to HetNets for intra-tier operation, by considering the network as one-tier.
- 2.
The large time scale can be of per hour level, while the small time scale can be of per second or millisecond levels.
- 3.
Note that the units of traffic arrival rate for the two models are different.
- 4.
- 5.
Notice that Proposition 1 applies to any sleeping schemes.
