Abstract: An RA-RNTI processing method, an apparatus, a terminal, and a readable storage medium are provided. The method includes: calculating an RA-RNTI based on time-frequency resource information of a random access occasion (RO) for sending a preamble, which includes: calculating the RA-RNTI based on a parameter t_id, where t_id is a slot number of a 1st slot of the RO occupied for sending the preamble within a first specified time, or a number of a 1st slot group of the RO occupied for sending the preamble, or a number of a 1st PRACH slot that is of the RO occupied for sending the preamble and that is in a slot group.

Abstract: A Random access Occasion (RO) time-domain resource configuration method and apparatus and an electronic device are provided. The RO time-domain resource configuration method is performed by a terminal, and includes: obtaining a subcarrier spacing of a reference time unit determined according to a first rule; and determining, based on a first information set and the subcarrier spacing of the reference time unit, RO time-domain resource configuration information that is in each subframe and that is used for transmitting a random access preamble. Parameters of the first information set are obtained in at least one of the following manners: parameters configured by second configuration signaling; obtained by extending the parameters configured by the second configuration signaling; parameters predefined by a protocol; or obtained by extending the parameters predefined by the protocol.

Abstract: The application discloses a random access method and apparatus, a terminal, and a storage medium. The method includes: determining, by a terminal, a random access occasion (RO) time domain position group; and selecting a first RO from the RO time domain position group and calculating a random access radio network temporary identifier (RA-RNTI) of the first RO. The RO time domain position group includes at least one of the following: a transmittable frame number group and a first slot number group, or a second slot number group.
