Abstract: This application provides a communication processing method for data transmission. A terminal-side device may adjust transmission of an uplink data burst in time based on time of arriving at an access stratum of the terminal-side device, a maximum peak rate, and a maximum data burst volume that are indicated by a network. This helps adapt to a network resource and improve a network load balancing capability.

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 data transmission method and an apparatus are provided. The method includes determining, by a first communication apparatus, that transmission of a first data packet has failed, the first data packet being transmitted in a first transmission manner; and sending, by the first communication apparatus, P data packets after the first data packet, the P data packets being sent in a second transmission manner, P is an integer greater than or equal to 1, and a second transmission reliability corresponding to the second transmission manner is greater than the first transmission reliability corresponding to the first transmission manner. In this way, because the first communication apparatus sends the P data packets after the first data packet in the second transmission manner, transmission reliability of the P data packets is improved, so that successful transmission of the P data packets can be effectively ensured, and service interruption can be avoided.
