Abstract: An interaction method and a terminal device. The terminal device receives a first location signal through a screen. An interface displayed on the screen includes an operation area and a display area, the operation area includes a first target area, and a page displayed in the display area includes a first target function. The terminal device determines, based on the first location signal, that a location of a touch point is in the first target area, and then the terminal device provides a first feedback used to introduce the first target function.

Abstract: A method and base station for transmitting a signal, including: generating n pieces of coordination information respectively corresponding to n coordinated base stations, where each piece of coordination information includes a cell identity CELL ID of a serving base station, a scrambling identity SCID of a user equipment UE, and information about a port number used by a corresponding coordinated base station, and the port number used by the coordinated base station is different from a port number used by the serving base station, and n is a positive integer; and respectively sending the n pieces of coordination information to the n coordinated base stations. These embodiments enable the coordinated base station to transmit a signal according to the coordination information of the serving base station, and require no transmit antenna calibration between RRUs of different cells, thereby avoiding the impact of transmit antenna calibration on CoMP JT performance.

Abstract: This application discloses example beam direction adjustment methods, apparatuses, and media. One example method includes obtaining at least one of an azimuth or a pitch angle of a microwave antenna in an antenna system, where the antenna system includes the microwave antenna and a radome installed at an air interface of the microwave antenna, the radome includes a liquid crystal array including M×N liquid crystal cells, and both M and N are integers greater than 0. A target scanning angle of the microwave antenna is determined based on at least one of the azimuth or the pitch angle. A first bias voltage value of the liquid crystal array is determined based on the target scanning angle. A voltage of the liquid crystal array is set to the first bias voltage value.

Abstract: The present disclosure discloses a distributed antenna system. The DAS includes a signal source, a first signal generator, a first passive mixer, and a first antenna. The first signal generator is configured to: generate a first local-frequency signal, and send it to the first passive mixer by using a passive DAS line. The first passive mixer is configured to receive the first local-frequency signal, and a downlink radio frequency signal having a second radio frequency band. The first passive mixer is further configured to: perform frequency mixing processing on the received downlink radio frequency signal having the second radio frequency band by using the first local-frequency signal, to form a first downlink radio frequency signal having a first radio frequency band, and then send it to the first antenna. The first antenna is configured to transmit the received first downlink radio frequency signal having the first radio frequency band.
