20150304963 | Method To Improve Throughput in Multi-SIM-Multi-Active Scenario Using Adaptive Transmit Blanking of Data and Control Channels - Various embodiments provide methods implemented on a multi-SIM-multi-active (MSMA) communication device for managing a victim subscription's de-sense by reducing transmit power of an aggressor subscription's data channel(s) before reducing transmit power of the control channel. When the victim is being/will be de-sensed, a processor of the MSMA communication device may determine a de-sense power threshold at which an aggressor subscription may transmit without de-sensing one or more victim subscriptions. The processor may reduce the transmit power of the aggressor subscription's data channel(s) to within the de-sense power threshold. If zeroing the aggressor subscription's data channel(s) transmit power is insufficient to avoid de-sense of the victim, the transmit power of the aggressor subscription's control channel may be reduced until the total transmit power of the aggressor subscription equals or is less than the de-sense power threshold. This reduces de-sense to the victim subscription with minimum impairment to the aggressor subscription's throughput. | 10-22-2015 |
