Abstract  Abstract

A method to support an asymmetric time-division duplex (TDD) configuration at a macro node in a heterogeneous network (HetNet) is disclosed. The method at the macro node comprises transmitting a half blank subframe (HBS) of a downlink subframe during an uplink subframe of a low power node in the HetNet. An effective transmission range of the macro node can overlap with an effective transmission range of the low power node. The downlink subframe and the uplink subframe can occur on a substantially same carrier frequency. The HBS can have a reduced transmission power during an uplink control channel or a random access channel of the uplink subframe of a mobile device transmission to the low power node.
