    摘要： Methods, devices, and systems embodiments enable a multi-antenna mobile device to mitigate radio frequency (RF) radiation exposure to users. A processor may determine a distance between the multi-antenna mobile device and the select portion of the user and switch from using a first antenna that is closer to the select portion of the user to using a second antenna when the multi-antenna mobile device is close to the user. The signal strength of the first antenna may be compared to the signal strength of a second antenna of the multi-antenna mobile device, and the second antenna may be used instead of the first antenna when the signal strength of the first antenna is within a predetermined threshold of the signal strength of the second antenna. If acceptable signal quality is not obtained with the second antenna, the multi-antenna mobile device may switch back to the first antenna.

    摘要： Embodiment methods and devices enable use of a shared radio resource on a multi-SIM wireless communication device to maintain session information on a service associated with one SIM during unused time slots of an active communication session associated with another SIM. During the session, a processor may calculate radio idle time periods in the active communication session, determine whether any of the radio idle time periods will exceed a predetermined threshold duration, and retune the shared radio resource to receive search samples on a frequency of the non-active network during radio idle time periods that exceed the predetermined threshold duration. Search samples may be stored for processing between radio idle time periods in order to maintain session information on a service associated with one SIM and provide service information to applications executing on the device during the active communication session.

    摘要： 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.
