Abstract: The present disclosure provides a downlink data transmission method, including: using a time-division multiplexing transmission mode in one transmission time interval; sending, by using a wide beam, a control signal to a user served in the current transmission time interval; and grouping users and sending data signals to different user groups by using different narrow beams. In one transmission time interval, time-division multiplexing is used, and a wide beam and a narrow beam are respectively used to transmit a control signal and a data signal. This can avoid a throughput bottleneck resulting from use of a transmission scheme that is based on frequency-division multiplexing only.

Abstract: A signal transmission method and apparatus are provided. The method includes: obtaining, by a transmitter, a to-be-sent data block; inserting one or more pilot blocks among a plurality of pieces of data of the to-be-sent data block based on an agreed position; and sending, by the transmitter, the to-be-sent data block into which the one or more pilot blocks are inserted. Inserting the one or more pilot blocks among the plurality of pieces of data of the to-be-sent data block can improve a phase noise compensation effect for a receiver without increasing pilot overheads.

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.
