摘要： The present disclosure relates to an electronic device in a wireless communication system and a wireless communication method. The electronic device comprises: one or more processing circuits, wherein the processing circuits are configured to execute the following operations: acquiring an on/off state of a small cell base station in a pre-determined geographical area; and on the basis of the acquired on/off state of the small cell base station, generating reconfiguration information about a positioning reference signal (PRS) used for the small cell base station in the pre-determined geographical area, so as to position user equipment in the pre-determined geographical area. By using the electronic device and the wireless communication method in the present disclosure, an existing PRS signal can be reconfigured, so as to improve the positioning accuracy, and achieve the purpose of accelerating the positioning process.

摘要： Optically sensitive devices include a device comprising a first contact and a second contact, each having a work function, and an optically sensitive material between the first contact and the second contact. The optically sensitive material comprises a p-type semiconductor, and the optically sensitive material has a work function. Circuitry applies a bias voltage between the first contact and the second contact. The optically sensitive material has an electron lifetime that is greater than the electron transit time from the first contact to the second contact when the bias is applied between the first contact and the second contact. The first contact provides injection of electrons and blocking the extraction of holes. The interface between the first contact and the optically sensitive material provides a surface recombination velocity less than 1 cm/s.

摘要： A photodetector is described along with corresponding materials, systems, and methods. The photodetector comprises an integrated circuit and at least two optically sensitive layers. A first optically sensitive layer is over at least a portion of the integrated circuit, and a second optically sensitive layer is over the first optically sensitive layer. Each optically sensitive layer is interposed between two electrodes. The two electrodes include a respective first electrode and a respective second electrode. The integrated circuit selectively applies a bias to the electrodes and reads signals from the optically sensitive layers. The signal is related to the number of photons received by the respective optically sensitive layer.
