Abstract: In order to improve the quality of communication between electronic devices, one or more sub-channels used during communication between the electronic devices are dynamically modified based on one or more performance metrics and allowed transmit powers of the sub-channels. In particular, when the one or more performance metrics indicate that a distance between the electronic devices falls within a mid-range of distances, the one or more performance metrics may be used to guide selective changes to the sub-channels used during the communication based on the allowed transmit powers. The changes to the sub-channels used during the communication may increase, decrease or leave the total bandwidth unchanged. Moreover, by changing the sub-channels used during the communication, the allowed transmit power(s) of the sub-channel(s) used may be increased, which may improve the performance during the communication.

Abstract: Manners of complying with SAR limits at a user equipment (UE) configured to establish a first communication connection using a first radio and a second communication connection using a second radio. The UE determines that a first application associated with the first communication connection is to be prioritized over a second application associated with the second communication connection, determines a specific absorption rate (SAR) value associated with the UE and modifies, responsive to the SAR value associated with the UE, a parameter associated with the first radio or the second radio based on at least the priority of the first application relative to the second application.

Abstract: The present disclosure relates to systems and methods for operating a control signal to communicate signals using a first antenna and a first frequency band in response to determining that intra-device operations are occurring or are expected to occur, that a first amount of energy received by the first antenna is less than a threshold amount of energy, and that the first antenna is unaffected by the intra-device operations. The control signal may also delay communication of the signals in response to determining that intra-device operations are occurring, and that first amount of energy is greater than or equal to the threshold amount of energy.

Abstract: Embodiments are disclosed for terahertz spectroscopy and imaging in dynamic environments. In an embodiment, a method comprises emitting a continuous electromagnetic (EM) wave in a terahertz (THz) frequency band into a dynamic environment. The EM THz wave is reflected off an object in the environment. A spectral response of a received signal indicative of the reflected EM wave is determined that includes absorption spectra at a frequency in the THz frequency band. The absorption spectra is indicative of a transmission medium in the environment. The spectral response of the received signal is compensated for fixed and frequency-specific losses. The compensated absorption spectra is compared with known absorption spectra of target transmission mediums. Based on results of the comparing, a particular target transmission medium is identified as being the transmission medium in the environment. The absorption spectra loss is used to determine a concentration level of the target transmission medium.

Abstract: Devices and systems useful in concurrently receiving and transmitting Wi-Fi signals and Bluetooth signals in the same frequency band are provided. By way of example, an electronic device includes a transceiver configured to transmit data and to receive data over channels of a first wireless network and a second wireless network concurrently. The transceiver includes a plurality of filters configured to allow the transceiver to transmit the data and to receive the data in the same frequency band by reducing interference between signals of the first wireless network and the second wireless network.

Abstract: Methods and apparatuses are presented to locate a wireless communication device. A target device may be out of range of a source device for normal ranging communications according to a first radio access technology (RAT), such as ultra wideband (UWB) communications. A source device may therefore modify communications according to the first RAT, to increase the transmit power, while removing the data payload. The target device may utilize the signal strength and angle of arrival of the modified communications to guide the user to move toward the source device, e.g., until the target device is within range to perform normal ranging communications. A second RAT, such as Bluetooth, may be used to communicate between the two devices while the target device is out of range of the first RAT. For example, the target device may use the second RAT to communicate to the source device to start/stop transmitting modified communications.

Abstract: Embodiments are disclosed for terahertz spectroscopy and imaging in dynamic environments. In an embodiment, a method comprises using a sensor of an electronic device to determine an orientation of the electronic device. A transmitter of the electronic device emits an electromagnetic (EM) wave in a terahertz (THz) frequency band into a dynamic environment according to a power duty cycle that is determined at least in part by the orientation. A receiver of the electronic device receives a reflected EM wave from the environment. A spectral response of the reflected EM wave is determined that includes absorption spectra that is indicative of the transmission medium in the environment. The absorption spectra are compared with known absorption spectra of target transmission mediums. Based on the comparing, a particular target transmission medium is identified as being the transmission medium in the environment, and a concentration level of the identified target transmission medium in the environment is determined.
