One ABS pattern is used for all small cells. Different small cells can have different downlink loads from user equipments (UEs). An embodiment method includes transmitting a pilot signal in a small cell, and determining downlink load (DLL) information according to a pair of measurements from each UE served by the small cell. The pair of measurements includes a first measurement of the pilot signal and a second measurement of a second pilot signal from a macro cell. The method further includes determining a number of ABSs according to the DLL information, and reporting the DLL information and the number of ABSs to a network entity for selecting ABS density and range extension for the small cell and the macro cell.

摘要： Embodiments are provided for implementing network adaptation schemes, including small cell on/off adaptation and transmission power control. In an embodiment method for supporting network adaptation, a network component receives a discovery reference signal (DRS) from a network controller that is in a switch-off transmission mode. The network component then performs measurements according to the DRS, and reports the measurements to a network associated with the network controller. In return, the network component receives a radio resource control (RRC) signaling from the network. The RRC signaling includes configuration information allowing a connection between the network component and the network controller. The network component then connects with the network controller in accordance with the configuration information.

摘要： A transmit power control rule for device-to-device (D2D) transmissions may not be necessary during periods in which no uplink transmissions are scheduled to be received by an enhanced Node B base station (eNB). When uplink transmissions are not scheduled to be received by the eNB, the eNB may send a transmit power control (TPC) command to a D2D capable user equipment (D2D UE) that instructs the D2D UE to perform a D2D transmission at a pre-defined transmit power level (e.g., maximum transmit power level). When uplink transmissions are scheduled to be received the eNB, the eNB may send a TPC command to the D2D UE that instructs the D2D UE to perform a D2D transmission at a transmit power level defined by a power control rule.
