The event processing method includes: determining first indication information, where the first indication information is used to indicate random access RA triggered by a first event or a second event, the first event refers to a quantity of transmissions of a scheduling request (SR) reaching a maximum quantity of transmissions of the SR, and the second event refers to, for an SR that has been triggered and that is in a pending state, there being no available physical uplink control channel (PUCCH) resource; and sending the first indication information.

The method includes: in response to receiving a paging message from a terminal device, a terminal device determines, based on a preconfiguration and/or the paging message, a first physical uplink shared channel (PUSCH) resource used to transmit a paging response, and sends the paging response to the access network device on the first PUSCH resource, where the paging response carries identity authentication information of the terminal device. After the access network device or a core network successfully performs identity authentication on the terminal device, downlink data transmission can be performed. Compared with a manner in which downlink data transmission can be performed only after a radio resource control (RRC) connection is set up or resumed, this manner can improve data transmission efficiency.

Communication method and apparatus

A data transmission method and an apparatus are provided. When a time-frequency resource used by a terminal device for data transmission is unavailable, the terminal device postpones, based on indication information of a network device and/or according to a postponement rule, the data transmission to a time-frequency resource closest to the time-frequency resource. Therefore, a data transmission latency is reduced.
