20130114434 | APPARATUS AND METHOD FOR ADAPTIVE TRANSMISSION DURING ALMOST BLANK SUBFRAMES IN A WIRELESS COMMUNICATION NETWORK - A system and method for communication in a wireless communication network are disclosed. One embodiment of the system includes an overlay access node that supports Almost Blank Subframes (ABSs). The overlay access node, such as macro eNB, can receive measurement results from one or more user equipments, including macro user equipments (UEs) and/or pico (UEs), either directly or via an underlay access node, such as a pico eNB. The macro eNB can determine a set of macro UEs that are sufficiently close to the macro eNB for transmission during ABSs with a low transmission power or beamforming without significant interference to the pico UEs. This scheme improves the throughput of transmission between the macro eNB and macro UEs while reducing interference to the pico UEs. | 05-09-2013 |
