DATA TRANSMISSION METHOD AND DEVICE

摘要

Embodiments of the present invention provide a method and a device for transmitting data relate to the technical field of communications and can effectively improve resource utilization of the system. The method for transmitting data includes: a user equipment receives downlink data sent from a base station through downlink resources of a special subframe; the user equipment determines its corresponding guard period level, the guard period level corresponds to a round-trip time of the user equipment and indicates a length of an orthogonal frequency division multiplexing (OFDM) symbol in a guard period corresponding to the user equipment in the special subframe; the user equipment determines, according to its corresponding guard period level, a position of uplink resources corresponding to the user equipment in guard period resources of the special subframe; and the user equipment sends uplink data to the base station through the uplink resources corresponding to the user equipment in the guard period resources of the special subframe. Embodiments of the present invention can be applied in a wireless communication system.
