1. A method for data transmission in an inactive state, comprising:
receiving, by a user equipment, configuration information from a network side device, wherein the configuration information is used to indicate whether at least one of at least one logical channel and a data radio bearer (DRB) of the user equipment supports data transmission in a Radio Resource Control (RRC) inactive state;
transmitting, by the user equipment, data to be transmitted on the at least one logical channel when the configuration information indicates that the at least one logical channel supports data transmission in the RRC inactive state; and transmitting, by the user equipment, data to be transmitted on a logical channel associated with the DRB when the configuration information indicates that the DRB supports data transmission in the RRC inactive state; and
initiating, by the user equipment, an RRC resume procedure when the configuration information indicates that the at least one logical channel does not support data transmission in the RRC inactive state and the user equipment has data to be transmitted for the DRB corresponding to the at least one logical channel; and transmitting the data to be transmitted when the user equipment resumes a connected state,
wherein the at least one logical channel is determined by:
determining, by the user equipment from a set of logical channels of the user equipment, one or more logical channels that have data to be transmitted, and using the one or more logical channels that have data to be transmitted as the at least one logical channel, and
wherein the at least one logical channel is multiple logical channels, and the transmitting, by the user equipment, the data to be transmitted on the at least one logical channel comprises:
in the RRC inactive state, determining, by the user equipment, whether the multiple logical channels support data transmission in the RRC inactive state based on the configuration information corresponding to each of the multiple logical channels; and
initiating, by the user equipment, data transmission in the RRC inactive state when the multiple logical channels all support data transmission in the RRC inactive state.
