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.

Abstract: Embodiments of the present invention include wireless communication systems having one or more network components that can communicate with at least one mobile station in an interference environment. A transmitter can transmit data indicating a set of communication modes in which a mobile station is capable of operating and for at least one mode of communication in the set an indication of interference rejection capability. The indicating data can be received by a receiver. A resource allocator can allocate system resources based on the indicating data for use during a connection between network components (e.g., a network apparatus and a mobile station). Allocation of system resources can fully or partially depend on a connection's communication mode, an indication of interference rejection capability of a mobile station for the mode of communication of the connection, and/or an interference environment expected during the connection.

Abstract: A tri-axial MEMS accelerometer includes a top cap silicon wafer and a bottom cap silicon wafer coupled with a measurement mass. The measurement mass has a two level structure, each level having an inner frame coupled to an outer frame by a plurality of first elastic beams, a mass coupled to the inner frame by a plurality of second elastic beams, and a comb coupling structure between the mass and the inner frame. The comb coupling structures are arranged in an orthogonal orientation. The top level and bottom level measurement masses measure acceleration in perpendicular directions. The top level and bottom level measurement masses and the inner frame form an integral unit which moves along a third direction. Acceleration in the third direction is measured from the change in capacitance between the integral unit and the top cap silicon wafer and bottom cap silicon wafer.
