1. A control information receiving method, comprising:

  • receiving, by a user equipment, a control information of a first cell, the control information indicating a first subframe in the first cell, a downlink data transmission length of the first subframe being less than a first threshold; and

    determining, by the user equipment, a last OFDM symbol of a first slot included in the first subframe does not include a primary synchronization signal and a second to last OFDM symbol of a first slot included in the first subframe does not include a secondary synchronization signal, when the first subframe is a first subframe in a radio frame or a sixth subframe in a radio frame, when a downlink data transmission configuration of the first cell is a normal cyclic prefix, and when the downlink data transmission length of the first subframe is less than 12 orthogonal frequency-division multiplexing (OFDM) symbols.
