Abstract: A Physical Uplink Shared Channel (PUSCH) transmission method by a User Equipment (UE) in a traffic adaptation system is provided. The method includes receiving, from a base station, a Physical Downlink Control Channel (PDCCH) for scheduling PUSCH resources, obtaining an Uplink (UL)-Grant in the PDCCH, determining a reference uplink and downlink configuration of the scheduled PUSCH resources in the PDCCH, based on at least one of the bit value of a UL-Index or a UL-Downlink Assignment Index (DAI) in the UL-Grant, and a serial number of a subframe in which the UL-Grant is located, and transmitting PUSCH data on the scheduled PUSCH resources according to a timing relationship corresponding to the reference uplink and downlink configuration.
