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.

Abstract: This application provides a random access method, a terminal, and a network device. The random access method includes: determining, by a terminal, whether a resource used for random access conflicts with a resource used for receiving a downlink signal; and if the resource used for the random access conflicts with the resource used for the downlink signal, preferentially using the conflicting random access resource for receiving the downlink signal but not for the random access. This avoids a conflict between receiving of the downlink signal and sending of an uplink random access preamble.

Abstract: A signal transmission method and an apparatus are provided, to resolve a problem, in a conventional technology, that transmission performance is poor when a signal is transmitted in a DFT-s-OFDM waveform. A transmitting end maps a plurality of modulation symbols to a plurality of layers, performs discrete Fourier transform (DFT) on a modulation symbol at a part of the layers to obtain a first symbol, and performs discrete Fourier transform DFT and phase offset on a modulation symbol at a remaining part of the layers to obtain a second symbol. Phase offset is performed on a symbol at a part of layers, so that a PAPR can be reduced.

Abstract: This application provides an uplink transmission method and an apparatus. The method includes: A network device indicates a terminal device to send a first transport block in a plurality of time units, and further indicates the terminal device to send uplink control information UCI in a first time unit. The first time unit is one of the plurality of time units. Regardless of whether the terminal device detects that the network device indicates the terminal device to send the UCI, both the network device and the terminal device calculate, based on a parameter G corresponding to the first time unit, a location of a starting bit in a coded bit sequence that is output through rate matching in a second time unit. The parameter G is a total quantity of coded bits available for transmission of the first transport block and the UCI in one time unit.
