Almost-Blank Subframe Configuration Detection in Heterogeneous Networks |
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.
