Abstract: Embodiments of this application disclose a modulation method. A first communication apparatus generates a first symbol stream based on a symbol type quantity, a probability distribution corresponding to a first symbol of each symbol type, a bit quantity corresponding to each first symbol, and a first original bit stream, the bit quantity corresponding to each first symbol is a bit quantity required by each first symbol that is represented by using a bit, and first symbols of different symbol types correspond to different probability distributions and/or different signal amplitudes; and the first communication apparatus generates a first quadrature amplitude modulation (QAM) symbol stream based on the first symbol stream and a second original bit stream.

Abstract: This application provides an initial access method and a communication apparatus to reduce an initial access delay and improve access efficiency, and can be applied to various communication systems such as a 5G system, a 6G system, a satellite communication system, an internet of vehicles system, and a V2X system. The method includes: A network device and a terminal device receive one or more SSBs on a time domain resource that carries a synchronization signal/physical broadcast channel SS/PBCH block SSB set in one SSB period, and access a network based on the received SSB. The SSB set is a set including one or more SSBs, a maximum value of a quantity of SSBs in the SSB set is Lmax, Lmax>64, and a time-frequency resource of the one or more SSBs is related to an SFN that carries the SSB.

Abstract: This application provides a communication method. The method includes: A terminal device receives a radio resource control RRC setup message from a network device. The RRC setup message includes a first parameter and first information. The first information is for configuring a scheduling-free uplink resource, and the first parameter is for determining valid duration of the scheduling-free uplink resource. The terminal device sends an RRC setup complete message to the network device on the scheduling-free uplink resource within the valid duration. In this way, scheduling-free transmission in an initial access phase is implemented.

Abstract: A synchronization signal block transmission method. When a terminal device receives at least one of N SSBs; and the terminal device determines a time position of a first SSB based on a number of the first SSB in the at least one SSB and a sending parameter, where the sending parameter is used to determine N candidate sending positions for transmitting the N SSBs in one periodicity T1, the N candidate sending positions are in at least two system frames, and the sending parameter includes one or more of the following parameters: a sweeping periodicity T3, a quantity of candidate sending positions included in each system frame, a time interval between two consecutive system frames of candidate sending positions included in each periodicity T1, and a quantity of system frames of the candidate sending positions included in each periodicity T1.
