Abstract
An opportunistic receive diversity scheme for VAMOS and similar deployments is disclosed. Receive diversity may be conditionally enabled when a VAMOS call is assigned to one of the SIMs of a mobile device. For example, receive diversity may be enabled when VAMOS data does not overlap with a time slot that is used by another subscription of the mobile device for receiving page messages. Also, receive diversity for a VAMOS call may be limited to situations where the VAMOS channel conditions are poor. Receive diversity may be enabled in cases where multiple subscriptions are assigned the same VAMOS channel, where VAMOS channel conditions have deteriorated, or where one of the subscriptions is not on a VAMOS channel. Also, receive diversity may be dynamically enabled for multiple subscriptions in cases where the subscriptions are assigned to different VAMOS channels.
