Abstract

A method and an evolved Node-B (eNB) for power saving in a heterogeneous network are provided in the embodiments of the present invention. According to the present invention, when the eNB serving an overlay capacity boosting cell does not detect any user equipments accessing the overlay capacity boosting cell, it turns off its downlink transmission; when the eNB serving the overlay capacity boosting cell detects that the user equipment is approaching its coverage area, it turns on its downlink transmission. That is, the eNB serving the overlay capacity boosting cell has two working states, a normal transmitting and receiving state, and a receiving state. The eNB serving the overlay capacity boosting cell autonomously turns on and turns off the downlink transmission according to the detection results of itself, instead of relying on the intervening or indication from the eNB serving an underlay basic coverage cell, so as to achieve the aim of power saving.
