Abstract: Method and apparatus, including computer programs, for providing a driver distraction signal and/or a system degradation signal indicating a reliability of the driver distraction signal, based on a gaze of a driver of a vehicle. Images of the driver of the vehicle are received, which contain information indicating a gaze of the driver. For each image, a gaze region for the driver is determined, including a gaze point and a gaze uncertainty value. For each image, the gaze region is associated with a region among several regions around the vehicle, wherein the regions include at least one pre-defined attentive region and at least one pre-defined inattentive region. Based on the determined gaze region, the gaze uncertainty value, and the region for a plurality of images, a driver distraction level and/or system degradation level indicating a reliability of the driver distraction level are determined.

Abstract: A method performed by a wireless device for enabling a determination of a reference signal configuration for downlink transmissions in a wireless communications network is provided. The wireless device obtains information indicating the number of used transform coefficients of the total number of transform coefficients determined in a transform-based channel estimator in the wireless device upon receiving a first downlink transmission according to a first reference signal configuration. Also, the wireless device determines, based on the obtained information, if the first reference signal configuration for downlink transmissions to the wireless device is to be modified or not. A wireless device for enabling a determination of a reference signal configuration for downlink transmissions in a wireless communications network is also provided. Further, a network node and method therein for determining a reference signal configuration for transmissions in a wireless communications network are provided.

Abstract: According to an aspect, a wireless device is configured to report, to a base station, channel quality information (CQI) using a predetermined set of CQI index values, where each CQI index value is interpreted by the wireless device and the base station as corresponding to a combination of modulation and coding rate. The wireless device determines, based on a downlink signal configuration, that a first one of the CQI index values corresponds to no modulation and coding rate that can be used for transmissions to the wireless device from the base station. The wireless device transmits the first CQI index value to the base station to signal information other than a combination of modulation and coding rate. The base station receives the first CQI index value and interprets it to signal information other than a combination of modulating and coding rate.
