1. A method for determining a subframe type, the method comprising:
determining a first subframe, wherein a subframe type of the first subframe is an uplink subframe or a downlink subframe in an existing Long Term Evolution (LTE) Frequency Division Duplex (FDD) system;
receiving UE-specific information in a preset resource at a specific period, wherein the UE-specific information is downlink control information (DCI), the UE-specific information is used for indicating that a subframe type of the first subframe is a special subframe or a preset subframe and notifying a downlink transmission component and an uplink transmission component comprised in the special subframe or the preset subframe, and the preset resource is a set of subframes notified in configuration signaling;
determining that the subframe type of the first subframe which is the uplink subframe or the downlink subframe is changed to the subframe type of the special subframe or the preset subframe comprising the downlink transmission component and the uplink transmission component; and
determining, according to the UE-specific information, the special subframe or the preset subframe in a preset period and an allocation scheme of the downlink transmission component and the uplink transmission component in the special subframe or the preset subframe, wherein the special subframe or the preset subframe is a subframe comprising at least uplink transmission resources and downlink transmission resources.
