Abstract
Methods and devices are disclosed for enabling improved transmission performance on a multi-SIM wireless communication device. The wireless device may detect a voice communication in a held state on a modem stack associated with the first SIM and an active voice communication on a modem stack associated with the second SIM. The wireless device may detect a conflict between at least one silence descriptor (SID) frame scheduled for transmission by the modem stack associated with the first SIM and a transmit opportunity for the modem stack associated with the second SIM. Once the wireless device identifies a SID frame transmission rate for the modem stack associated with the first SIM, the wireless device may apply a reduction scheme to the SID frames scheduled to be transmitted by the modem stack associated with the first SIM.
