Abstract
Devices and methods are configured for resolving control channel transmission collision in a mobile device having first and second subscriptions (SUBs) when the first SUB is in an active voice call and the second SUB is in a held voice call. The devices and methods involve determining whether a control channel transmission of the first SUB would collide with a control channel transmission of the second SUB. In response to determining that the first SUB control channel transmission would collide with the second SUB control channel transmission, the devices and methods alternate the first SUB control channel transmission and the second SUB control channel transmission to avoid collision.
