20150282190 | INTERFERENCE CANCELLATION RECEIVING METHOD AND INTERFERENCE CANCELLATION RECEIVING TERMINAL - One embodiment of the present specification provides an interference cancellation receiving method. According to the method, interference estimation support information can be received from a serving cell. The information includes information for a time domain and information for a frequency domain, wherein the information for a time domain can indicate a section of a subframe or a radio frame in which the coherence of an interference signal is maintained, and the information for a frequency domain can indicate a section in which the coherence of the interference signal is maintained. According to the method, an interference signal introduced from a neighboring cell is estimated by using the information for a time domain and the information for a frequency domain of the interference estimation support information, and a signal from the serving cell can be detected by cancelling the estimated interference. | 2015-10-01 |
20150282191 | CSI REPORT WITH DIFFERENT RECEIVER CAPABILITIES - Reported CSI may not reflect non-cancelable CRS interference received from an interfering cell, such as when the CSI is computed when CRS interference is not received. To address the issue, a user equipment (UE) may determine an interference cancelation/suppression efficiency (CSE) associated with canceling/suppressing interference from interfering cells. In addition, based on the determined CSE, a UE may compute CSI such that the CSI reflects the true cancelation efficiency of the UE with respect to interfering cell signals. When computing the CSI based on the determined CSE, the UE may report that the CSI is worse than it is to reflect the UE's true cancelation efficiency with respect to the interfering cell signals. | 2015-10-01 |
