Abstract: This application provides a random access method and apparatus. In the method, a terminal device may determine a first random access resource for sending a random access preamble by using reference signal grouping information. This helps the terminal device send the random access preamble to a network device on the first random access resource, thereby improving a random access success rate.

Abstract: This application provides a signal transmission method and apparatus, a reflector, and a receiver. In one example method, a reflector receives W excitation signals, where W exciters may be configured to carry data and a reference signal that are reflected by the reflector; and the reflector reflects data and L reference signals to a receiver, where the L reference signals are respectively carried in L excitation signals in the W excitation signals, where W and L are both integers greater than or equal to 1, and L is less than or equal to W.

Abstract: This disclosure describes signal transmission methods and apparatus. On example method includes: receiving, by a terminal device, a paging indication sent by a network device, where the paging indication carries information about a plurality of paging groups; and sending, by the terminal device to the network device based on an association relationship between a paged paging group in the plurality of paging groups and a random access preamble, a random access preamble associated with a paging group in which the terminal device is located.

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.
