This letter aims to enhance the energy-efficiency (EE) for hyper-dense small-cell networks by designing a low-complexity sleep strategy for base-stations (BSS). First, four operation modes are considered for BSS, i.e., active, standby, sleep, and off. To be specific, the active, standby, and sleep modes are for serving the delay-intolerant, delay-sensitive, and rate-sensitive demands. Second, the BSS with lower EE are iteratively considered to switch into lower-energy operation modes, if all the users with stringent delay requirement can be reassociated with the quality-of-service (QoS) provision. To improve the success rate of reassociation, all the BSS that can reach the predefined QoS can be the feasible targets. Compared with the conventional schemes, a remarkable 72% and 51% enhancement of EE can be achieved and more BSS can operate in the lower-energy modes.
