    摘要： A method and a user equipment in a network having a macro cell and at least one small cell, the method in one embodiment receiving a measurement restriction over a broadcast channel from the macro cell; and applying the restriction for a corresponding measurement at the user equipment. In one embodiment the method includes receiving a small cell list from the macro cell; and measuring at least one of a reference signal receive power and a reference signal received quality based on the received small cell list. The method includes, in one embodiment, receiving a neighboring small cell configurations from the macro cell; and utilizing the received small cell configurations to attach to a small cell. The method includes, in one embodiment, receiving an s-measure offset value over a broadcast channel from the macro cell; and applying the s-measure offset value to an s-measure for neighbor cell discovery.

    摘要： In a system for allocating resources of a wireless communication system power levels of downlink (DL) communication channels and coupling losses of uplink (UL) communication channels are determined. When the power level of the DL communication channel between a base station and a UA is greater than the power levels of the DL communication channels between each of a plurality of RNs and the UA, and the coupling losses of the UL communication channel between at least one of the RNs and the UA are less than the coupling losses of the UL communication channel between the base station and the UA, a DL communication channel resource on the base station to the UA, and a UL communication channel resource on the at least one of the plurality of RNs to the UA are allocated.
