Abstract: This application relates to communication methods and communication apparatuses. In an example method, a terminal device or a chip in the terminal device obtains first information. The first information is used to determine an access range corresponding to a first signal. In response to determining that the terminal device is located in the access range after a first moment, the terminal device or the chip in the terminal device sends a first random access preamble. The first random access preamble is associated with the first signal.

Abstract: A communication method and apparatus are provided to reduce interference between different types of satellites. The method is: A terminal device determines a satellite type corresponding to a first area, and the terminal device determines, based on the satellite type, whether to access a network device covering the first area. The terminal device determines, based on the determined satellite type corresponding to the first area, whether the network device can be accessed, so that a type of the network device accessed by the terminal device is consistent with the satellite type of the first area, and the terminal device can access only one type of satellite. When a plurality of types of satellites reuse a same frequency, the terminal device may receive signals of the plurality of types of satellites in the first area.

Abstract: This application provides a data sending method and an apparatus. The method includes: A first device sends, to a second device, first data modulated by using a first quadrature amplitude modulation codebook. The second device receives, from the first device, the first data modulated by using the first quadrature amplitude modulation codebook. When the second device fails to decode the first data modulated by using the first quadrature amplitude modulation codebook, the first device sends, to the second device, second data modulated by using a second quadrature amplitude modulation codebook. The second data is a part or all of the first data, and the first quadrature amplitude modulation codebook is different from the second quadrature amplitude modulation codebook. The second device receives, from the first device, the second data modulated by using the second quadrature amplitude modulation codebook, and jointly decodes the first data and the second data.

Abstract: A terminal determines a validity duration of a first parameter and a validity duration of a second parameter. The first parameter includes positioning information of the terminal, and the second parameter includes one or more of the following information: ephemeris information of a serving satellite and common timing advance (TA) information. Then, the terminal determines an invalidation moment of the first parameter and an invalidation moment of the second parameter based on a validation moment of the first parameter, a validation moment of the second parameter, the validity duration of the first parameter, and the validity duration of the second parameter. The terminal updates the first parameter and the second parameter at or before an earlier invalidation moment in the invalidation moment of the first parameter and the invalidation moment of the second parameter. The terminal determines a TA adjustment value based on an updated first parameter and an updated second parameter.
