Abstract: Embodiments of the present disclosure relate to a short control signaling transmission for sidelink communication in an unlicensed spectrum. According to one aspect of the present disclosure, if a control signaling is to be transmitted to a second device via a short control signaling transmission, a first device determines whether the short control signaling transmission is available based on at least information related to a counter, the counter being used for counting occasions within a period for the short control signaling transmission at a sidelink interface. If the short control signaling transmission is available, the first device transmits the control signaling to the second device on a first resource configured for the short control signaling transmission. In this way, constraints for the usage of the short control signaling transmission can be satisfied, and a reliable transmission of sidelink control signaling in the unlicensed spectrum can be achieved.

Abstract: An electronic device may have an ambient light sensor for gathering ambient light measurements. The ambient light sensor may include multiple channels for measuring different wavelengths of ambient light. An additional, modified, channel may be formed in the ambient light sensor to measure radio-frequency signals that may interfere with the ambient light measurements due to electromagnetic interference. Alternatively, circuitry separate from the ambient light sensor, such as an antenna, may measure the radio-frequency signals. If the radio-frequency signals exceed a threshold, the ambient light sensor measurements taken in the presence of the radio-frequency signals may be discarded or corrected. If the radio-frequency signals do not exceed a threshold, the ambient light sensor measurements may be kept. Therefore, the ambient light measurements that are kept and relied upon by the electronic device may be free from electromagnetic interference.
