Abstract: A cell search method and a communication apparatus. The method comprises: before performing cell search, a terminal device can determine, in combination with the historical access information of other terminal device, whether a cell exists at the position, and adjusts, according to the determination result, the value of the search parameter for cell search, for example, if a cell exists, the search is accelerated by adjusting the search parameter; if no cell exists, the search may not be performed or the search parameter may not be adjusted, so as to reduce unnecessary cell search performed by the terminal device, so that the power consumption of the terminal device can be reduced.

Abstract: A first electronic device determines that a first trigger condition is satisfied, sends a first instruction to enable a first sound wave transmitter to send a first sound wave signal, and sends a second instruction to enable a second sound wave transmitter to send a second sound wave signal. A second electronic device sends a third instruction to enable a first sound wave receiver to receive the first sound wave signal and the second sound wave signal, calculates a first receiving start moment and a second receiving start moment, obtains first location information, determines second location information based on the first receiving start moment, the second receiving start moment, and the first location information, and sends the second location information to the first electronic device. The first electronic device updates third location information by using the second location information.

Abstract: Embodiments of this application disclose a wireless access point deployment method and apparatus. In the method, after receiving a first operation, a terminal device displays a floor plan determining interface. Then, the terminal device receives a second operation for the floor plan determining interface, and determines a first floor plan based on the second operation. The terminal device determines an AP type recommended to be deployed currently. Next, the terminal device displays an AP deployment interface based on the first floor plan and the AP type, where the AP deployment interface is used to display a quantity of APs recommended to be deployed and locations of the APs recommended to be deployed.

Abstract: A cell search method and a communications apparatus are provided. The method includes the following: before searching for a cell, a terminal device may determine, with reference to historical access information of another terminal device, whether there is a cell at the location, and adjust, based on a determining result, a value of a search parameter used to search for a cell. For example, if there is a cell, the terminal device may adjust the search parameter to accelerate a search. If there is no cell, the terminal device may perform no search, or adjust the search parameter to reduce an unnecessary cell search performed by the terminal device, so that power consumption of the terminal device can be reduced.

Abstract: This application discloses a pulse shaping method, a transmitter, a receiver, and a system. The transmitter includes an inverse Fourier transform module, a pulse shaping filter, a pulse shaping controller, and a parallel-to-serial conversion module. The pulse shaping controller is configured to: receive pulse configuration signaling, generate, based on the pulse configuration signaling, a pulse parameter corresponding to a to-be-configured pulse, and output the pulse parameter to the pulse shaping filter. The pulse shaping filter is configured to: perform subcarrier-level filtering on an output signal of the inverse Fourier transform module, perform pulse shaping processing on the output signal of the inverse Fourier transform module based on the pulse parameter, and output a processed signal in serial by using the P/S module. Different pulse parameters correspondingly represent different pulse shapes. In the foregoing solution, pulse shaping can be flexibly configured, to support different communication scenarios.
