Abstract: The present disclosure relates to signal transmission methods and apparatuses. In one example method, a transmitting end groups multiple modulation symbols into multiple groups of modulation symbols, and adds one or more preset symbols to each group of modulation symbols to obtain extended symbols. Then, the transmitting end performs second-level precoding on at least one group of extended symbols corresponding to each group of antenna ports to obtain a symbol corresponding to each antenna port in each group of antenna ports. In the second-level precoding, a dimension of a precoding matrix for each group of precoding antenna ports is related to a quantity of groups and a quantity of antenna ports included in the group of antenna ports. Finally, the transmitting end sends the symbol corresponding to each antenna port.

Abstract: A PTRS processing method and an apparatus. The method includes: receiving, by a terminal, first indication information and second indication information from a network device, where the first indication information is used to indicate a time-domain location at which a PTRS is to be sent by the terminal, and the second indication information is used to indicate an offset of an initial time-domain location to which the PTRS is mapped by the terminal; mapping, by the terminal, the PTRS to one or more DFT-s-OFDM symbols based on the first indication information and the second indication information; and sending, by the terminal, the one or more DFT-s-OFDM symbols. In this way, the PTRS mapped to the DFT-s-OFDM symbol is offset at a DFT-s-OFDM symbol level, so that PTRS collision between terminals can be avoided to an extent, thereby improving phase tracking precision.
