Abstract: Various embodiments provide methods, devices, and non-transitory processor-readable storage media for mitigating local oscillator (LO) spur interference between radio access technologies (RATs) operating on a multi-active communication device. The various embodiments provide methods, devices, and non-transitory processor-readable storage media to determine residual frequency error for a multi-active communication device and generate LO spur handling tables that may enable the multi-active communication device to compensate for the residual frequency error. A multi-active communication device may mitigate LO spurs by applying mitigation techniques to one or more RATs according to the LO spur handling tables. A multi-active communication device may mitigate LO spurs by turning off a LOs for one or more RATs according to the LO spur handling tables.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for enhancement of replay protection between receivers and transmitters from third party interveners in wireless communication systems. One example method generally includes transmitting one or more packets, wherein each of the packets comprises an indication of a packet number associated with that packet; determining that a condition has been met or exceeded; and based on the determination, transmitting a message indicating a packet number increase. Another example method generally includes receiving a first packet comprising an indication of a first packet number; receiving a message indicating a packet number increase; updating a packet number window based on the packet number increase; after the updating, receiving a second packet comprising an indication of a second packet number; and discarding at least a portion of the second packet if the second packet number is outside the packet number window.
