Abstract: This application discloses a communication method and a communications apparatus. The method includes: determining, by a terminal device, transmission power for sending a random access preamble, where the transmission power is related to a random access preamble format and an offset based on the random access preamble format; and sending, by the terminal device, the random access preamble at the determined transmission power. The random access preamble format includes some or all of 0 to 3, A0 to A3, B1 to B4, C0, and C2. The corresponding apparatus is further disclosed. In this application, offsets corresponding to a plurality of random access preamble formats in a next-generation mobile communications system are provided, so that the transmission power of the random access preamble can be properly determined.

Abstract: This application discloses a communications method and apparatus. The method includes: obtaining, by a terminal device, downlink synchronization signal block index information; receiving, by the terminal device, information used to indicate an association relationship between a random access resource RO and a synchronization signal block; and accessing, by the terminal device, a network device based on the information on an RO corresponding to the synchronization signal block index information. This application further discloses a corresponding apparatus. A time-frequency location of a random access resource associated with each downlink synchronization signal is indicated, so that the terminal device obtains, through downlink synchronization, a time-frequency location for sending an uplink random access signal, to avoid a blind attempt of the terminal device and a beam mismatch of the network device occurring when the network device receives a random access signal, thereby improving efficiency.
