A system comprising a relay device that configures to a first beamforming setting for a first set of antenna arrays to establish a first link between the relay device and a source device, and a second beamforming setting to establish a second link between the relay device and a destination device. A data stream is processed based on a selection of one of a passive mode or an active mode of relay operation. In the passive mode, a received radio frequency waveform of the data stream is down-converted to an intermediate frequency waveform, re-amplified, and then up-converted for transmission without requiring any data demodulation, and in the active mode, the IF waveform is demodulated and then remodulated for the transmission. The data stream is forwarded to the destination device through the second link based on the selection of one of the passive or active mode.

A system of one or more computers can be configured to perform particular operations or actions by virtue of having software, firmware, hardware, or a combination of them installed on the system that in operation causes or cause the system to execute intelligent thermal management of a WWAN modem. In at least one embodiment, the temperature conditions associated with the operation of the WWAN modem and the current communication conditions of the WWAN modem are detected. The detected temperature conditions and current communication conditions are provided to an input of a trained thermal AI/ML model, which generates a set of new communication parameters. In at least one embodiment, the WWAN modem is set to operate using one or more of the new communication parameters.

Devices exchange control signals with each other to ensure proper operation of an overall system. For instance, in a communication system, a baseband processor and a transceiver communicate with each other to exchange information for controlling the respective signal processing parts of the baseband processor and the transceiver. While Serial Peripheral Interfaces (SPIs) can be used, SPI can be extremely slow, and does not provide a protocol for allowing a complex set of control signals to be exchanged between the baseband processor and transceiver. The present disclosure describes a fast control interface which can support various modes of operation in allowing two devices to communicate with each other quickly and effectively.
