Abstract: Frequency selective almost blank subframes (ABS) are scheduled in a heterogeneous network in which a protected portion of an available frequency band is allocated to protected subframes transmitted in by a small cell during a first time period and an unprotected portion of the frequency band is allocated to non-protected subframes transmitted during the first time period by the macro cell. The macro cell in the heterogeneous network utilizes the unprotected portion of the frequency band to transmit data to served user equipment (UEs) during ABS while the small cell uses the protected portion of the frequency band to transmit data to served UEs during ABS. That can improve service to low latency applications both for UEs served by the macro cell and for UEs being served by the small cell(s).
