1. A method, comprising:
receiving, by a terminal, first indication information from a network device, wherein the first indication information comprises slot aggregation information of a physical uplink shared channel (PUSCH) to use in a random access procedure for early data transmission;
selecting, by the terminal according to the slot aggregation information of the PUSCH to use in the random access procedure for early data transmission and a size of first uplink data to send in the early data transmission, preamble information for the random access procedure or resource information for the random access procedure, wherein selecting, by the terminal according to the slot aggregation information of the PUSCH to use in the random access procedure for the early data transmission and the size of the first uplink data to send in the early data transmission, the preamble information for the random access procedure or the resource information for the random access procedure comprises:
when the size of the first uplink data to send in the early data transmission is not greater than a first transport block size (TBS), selecting, for the random access procedure, preamble information corresponding to slot aggregation not being performed for the PUSCH in the random access procedure or random access channel resource information corresponding to slot aggregation not being performed for the PUSCH in the random access procedure; or
when the size of the first uplink data to send in the early data transmission is greater than the first TBS, less than a product of the first TBS and a first slot aggregation level, and less than a product of the first TBS and a second slot aggregation level, selecting, for the random access procedure, first preamble information corresponding to the first slot aggregation level or first random access channel resource information corresponding to the first slot aggregation level, wherein the first slot aggregation level is less than the second slot aggregation level; and
performing, by the terminal, early data transmission based on the first indication information.
