    Abstract: Various aspects of the present disclosure provide for an apparatus configured to receive a transmission from a serving cell utilizing a single antenna while the apparatus is operating in a first mode. While the apparatus is operating in a second mode, the apparatus may be configured to measure a signal quality of a neighbor cell utilizing at least one of two or more antennas and use receive diversity (RxD) to receive the transmission from the serving cell utilizing the two or more antennas. While the apparatus is operating in a third mode, the apparatus may be further configured to use only RxD to receive the transmission from the serving cell utilizing the two or more antennas. The first mode may be a single-antenna mode. The second mode may be a hybrid-antenna mode. The third mode may be an RxD-only mode.

    Abstract: Methods are provided that optimize Voice over Adaptive Multi-user channels on One Slot (VAMOS) communications by recognizing that up to four independent communications are located on the same device, and assigning them to sub-channels of the same VAMOS channel. A VAMOS-capable multi-SIM wireless device such as a dual-SIM dual active (DSDA) device may have up to four simultaneous active calls on the same access network. When assigned to the same VAMOS channel, the up to four active calls may be merged to all use the same radio on the device.
