Abstract: Embodiments of this application provide a random access processing method. A random access preamble and uplink data are sent in an initiation phase of a random access procedure, and the random access procedure is ended in time after feedback information for the uplink data is received. According to technical solutions provided in the embodiments of this application, a terminal side device may send the uplink data when sending the random access preamble in the random access procedure. In addition, the random access procedure can be ended in advance after the feedback information for the uplink data is received.

Abstract: A communication method, a communications apparatus and a non-transitory computer-readable medium are provided. A network device receives data carried on a first scheduling-free resource via a first hybrid automatic repeat request (HARQ) process from a terminal device, and decodes the data to generate HARQ feedback information. The network device sends downlink control information (DCI) to the terminal device, where the DCI includes the HARQ feedback information and first indication information. The first indication information indicates the first HARQ process.
