摘要： A method for configuring communication in a wireless communication system includes obtaining, at a first network node, information indicating a plurality of candidate subframes for downlink transmissions to a wireless communication device in a first cell served by the first network node. Each candidate subframe satisfies a candidate condition that relates to transmissions in a second cell during that subframe. The method also includes determining, based on the obtained information, a number of copies of an uplink transmission a wireless communication device should transmit in consecutive uplink subframes so that a downlink transmission related to the uplink transmission will occur during one of the candidate subframes. Additionally, the method includes configuring the wireless communication device to transmit the determined number of copies of the uplink transmission in consecutive subframes.

摘要： A method for detecting an Almost-Blank Subframe (ABS) configuration for an interfering macro cell of a heterogeneous network is implemented in a wireless terminal. For one or more resource blocks in a received signal, a first power metric is calculated as a function of channel response estimates determined for predicted cell-specific (or common) reference signal (CRS) resource element locations in a plurality of symbols. For the one or more resource blocks in the received signal, a second power metric is calculated as a function of channel response estimates determined for the predicted CRS resource element locations in a single one of the plurality of symbols. A difference between the first and second power metrics is compared to a threshold, and responsive to the comparison a determination is made as to whether the macro cell is operating in a Multicast and Broadcast Single Frequency Network (MBSFN) mode or a non-MBSFN mode.

摘要： A wireless communication node (10) dynamically estimates passive intermodulation (PIM) interference coupled into the node's receive path from the transmission of a composite signal through the node's transmit path. The node (10) then cancels the estimated PIM interference in the receive path. In some embodiments, the node dynamically estimates the PIM interference as a function of the composite signal that models PIM interference generation and coupling in the node (10) according to one or more coefficients (30). The coefficients (30) may be determined by transmitting a test signal (34) during a test stage, when the node (10) is not scheduled to receive any signal. Later, when the composite signal (18) is transmitted, the node (10) uses the coefficients (10) to dynamically estimate and cancel the resulting PIM interference.
