Abstract: User equipment includes a first antenna, a second antenna, a first transceiver coupled to the first antenna, a second transceiver coupled to the second antenna, and processing circuitry communicatively coupled to the first transceiver and the second transceiver. The first transceiver receives or transmits a first signal via the first antenna, and the second transceiver receives or transmits a second signal via the second antenna. The processing circuitry receives an indication that a signal characteristic of the first signal is less than a first threshold, and decreases power to the first antenna, the first receiver, or both, based on the signal characteristic of the first signal being less than the first threshold.

Abstract: Apparatuses, systems, and methods for RACH procedures to avoid excessive handover/secondary cell group failures. A base station may declare a handover and/or secondary cell group (SCG) failure and may determine that a failure threshold has been met. The base station may perform a remedial action in response to meeting the failure threshold. The failure threshold may be multi-dimensional, where a first dimension is associated with a number of handover/SCG failures and where a second dimension is associated with a time period in which the number of handover/SCG failures occurred. Further, a third dimension may be associated with a UE mobility state and a fourth dimension may be associated with whether the UE is using FR1 or FR2. The remedial action in response to meeting the failure threshold may include the base station suspending transmission of measurement object configurations for a specified period of time.
