  • Patent number: 9949196
    Abstract: A method, device, and system provide efficient way for handling LTE cells for suspending data suspending data in a carrier aggregation plus multiSIM scenario. The technique includes receiving communications corresponding to the first subscription at a user equipment over a primary cell and a secondary cell; calculating, prior to a tune away period, a first data throughput rate of the primary cell and a second data throughput rate of a secondary cell; sending at least one event measurement report if the second data throughput rate is higher than the first data throughput rate; receiving a handover command from a network node to interchange the primary cell and the secondary cell; and switching, in response to receiving the handover command, the primary cell and the secondary cell such that the primary cell becomes the secondary cell and the secondary cell becomes the primary cell for first subscription traffic.

  • Patent number: 9848408
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE which uses a first antenna and a second antenna for communication with a first RAT. The apparatus determines that the second antenna is to be used for a procedure associated with a second RAT at a first time. The apparatus reduces a UE RI from an initial value to a reduced value for the communication with the first RAT at the first time based on the determination.

  • Patent number: 9198180
    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.

  • Patent number: 9131475
    Abstract: A method and apparatus configured to perform fast acquisition in multi-subscription multi-active devices are described. The apparatus may establish a first traffic call associated with a first subscription using a first radio frequency chain and a second traffic call associated with a second subscription using a second radio frequency chain. A subscription corresponding to a third subscription may enter an out-of-service mode when the first and second traffic calls are established. A first network may be acquired for the first subscription using the first RF chain after the first traffic call is terminated. The third subscription may be transitioned from out-of-service mode to idle mode using acquisition information inherited from the subscription corresponding to the first SIM after the first network is acquired. The third subscription and the first network may be associated with a same radio access technology and a same network operator.
