Abstract: An electronic device display may have an active area with pixels. An optical sensor may be formed under a sensor region in the active area. During operation, ambient light and/or other light associated with the optical sensor may pass through the sensor region. To ensure that the light for the optical sensor can pass through the display, the display may have one or more layers with sensor openings such as a metal layer and a pressure sensitive adhesive layer that attaches the metal layer to the pixels of the display. To help minimize visibility of the openings in the sensor region, the pressure sensitive adhesive layer may be configured to have a reflectivity that matches the appearance of the display in the sensor region to surrounding areas. Undesired light output uniformity can be reduced by ensuring that the substrate material in the display has a low light absorption coefficient.

Abstract: Apparatuses, systems, and methods for performing uplink and downlink communication in cell edge scenarios with improved reliability. A wireless device may establish a radio resource control connection with a first cell. The wireless device may determine that a second cell strongly interferes with communication with the first cell. The wireless device may provide an indication that the second cell is a strongly interfering cell to the first cell. The first cell may coordinate with the second cell to transmit data to the wireless device, and to receive data from the wireless device, based at least in part on the indication that the second cell is a strongly interfering cell.

Abstract: This disclosure relates to techniques for a wireless device to dynamically adapt its bandwidth use using network scheduling information in a cellular communication system. A radio resource control connection between a cellular base station and a wireless device may be established. The wireless device may receive network scheduling information from the cellular base station. The wireless device may dynamically select a receive bandwidth for receiving transmissions from the cellular base station based at least in part on the network scheduling information.

Abstract: A base station may transmit to a device an indication of codebook subset restriction (CBSR), which includes at least a restriction on a frequency basis. The device may receive the indication of CBSR, and may transmit to the base station channel state information (CSI) according to the received indication of CBSR. The indication of CBSR may also include a restriction on a spatial basis and restrict the device from reporting the CSI based on a subset of the frequency basis in addition to the spatial basis per configuration of the base station. The indication of CBSR may include a separately configured maximum allowed amplitude of a weighting coefficient for the spatial basis and the frequency basis, where the weighting coefficient is associated with a column vector of a precoding matrix used by the base station and the device. The number of frequency bases and the frequency compression units may be determined based on a number of different criteria, for example the number of antennas, the number of subbands, etc.
