摘要： A base station node (BS) of a heterogeneous radio access network comprises a terminal locator (34) and a scheduler (36). The terminal locator (34) obtains an indication of location of a wireless terminal (30) in a cell served by the base station (BS), e.g., whether the wireless terminal (30) is in a center region (M) or an edge region (E) for the cell served by the base station node (BS). The scheduler (36) uses the indication of location to assign to the wireless terminal (30) a frequency of a frequency bandwidth usable by the heterogeneous radio access network. The scheduler (36) assigns a frequency from a partitioned portion of the frequency bandwidth if the cell served by the base station node is a micro cell (28) and the wireless terminal is in an edge region of a micro cell (28). The scheduler (36) also assigns a frequency of the frequency bandwidth if the cell served by the base station node is a micro cell (28) and the wireless terminal is in a center portion of the micro cell (28).

摘要： The invention relates to a method for measuring signal interference from an interfering transceiver node (200) of a mobile communications network to a user equipment (100) served by a serving transceiver node (300). The interfering transceiver node (200) uses a plurality of defined radiation patterns for signal transmission, wherein a transmission of a sequence of the defined radiation patterns by the interfering transceiver node (200) is triggered. Furthermore, signal measurements of the signal transmitted by the interfering transceiver node (200) that uses the sequence of the defined radiation patterns are triggered at the user equipment (100) and an interference level of the signals received at the user equipment (100) is estimated from the interfering transceiver node (200) in dependence on the sequence of the defined radiation patterns, wherein the interference level is estimated based on the triggered signal measurements received from the user equipment (100).
