Abstract: A random access method and apparatus, a terminal, and a network side device are provided. The method includes: determining, by the terminal, a first signal related parameter based on terminal identifier related information. The method further includes sending, by the terminal, a first signal based on the first signal related parameter. The first signal includes at least one of a Sounding Reference Signal (SRS) or a preamble of a first random access message. The first signal related parameter includes at least one of the following: sequence identification information of the first signal; a time domain resource for the first signal; or a frequency domain resource for the first signal.

Abstract: This application discloses an information transmission method and apparatus, a device, and a storage medium. The method is performed by a communications device, and includes: obtaining channel quality of a plurality of antenna channels; and determining an antenna operation mode based on the channel quality, and transmitting information. The antenna operation mode includes: a MIMO mode, an FTN mode, or a MIMO-FTN mode in which the same antenna port group in the plurality of antenna channels operates in a MIMO precoding manner and different antenna port groups operate in an FTN manner, where each antenna port group includes at least one antenna channel.
