摘要： 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.

摘要： Systems, methods, and apparatuses for phase-rotated reference signals are provided. In accordance with one implementation, phase-rotated reference signals are transmitted from multiple transmit antennas on the same reference signal (RS) resource elements. The receiver may determine channel coefficients for links corresponding to the multiple antennas, based on the received signals at the RS resource elements. Time-domain filtering or frequency-domain orthogonal codes may be used to determine the channel coefficients for links corresponding to the multiple antennas. The phase-rotation information may be broadcasted in a system information block (SIB) message or signaled in a radio resource control (RRC) message.

摘要： 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.
