In heterogeneous networks, Macro eNodeBs reduce transmit power on almost blank subframe (ABS) so that Pico cell range expansion(CRE) users could be protected from cross-layer interference. However, few focus on power reduction and user QoS constraints. In this paper, a joint resource allocation and ABS power control algorithm(RA-APC) is proposed. The algorithm is carried out by iterating between RA and APC under user QoS constraints. Simulation results show that the proposed algorithm converges fast and improves overall network utility.
