Abstract: A method for transmitting information, a base station, and a user equipment, where the method includes determining, by a user equipment, a timing advance T of a signal before sending the signal; determining, by the user equipment, an indication N of a timing adjustment according to at least the T; and sending, by the user equipment, scheduling assignment signaling that carries the N. By using allocation of non-identical time-frequency resources to different user clusters, the scheduling assignment signaling that carries the timing advance sent by the user equipment can bear more useful information, thereby avoiding unnecessary waste.

Abstract: A data transmission method and an apparatus relate to the communications field and are applied to data transmission to effectively reduce a collision reoccurrence probability after a device in a licensed-assisted access using Long Term Evolution (LAA-LTE) system preempts an unlicensed spectrum and collides with another device. A first device adjusts a detection moment or a quantity of detection times of clear channel assessment (CCA) of a channel in an unlicensed spectrum after the first device determines that the first device collides with another device when occupying the channel in the unlicensed spectrum to transmit data, and the first device occupies, according to an adjusted detection moment or an adjusted quantity of detection times of CCA of the channel in the unlicensed spectrum, the channel in the unlicensed spectrum to transmit data.

Abstract: The present invention discloses an information transmission method, a device, and a system, and relates to the communications field, so as to resolve a problem that a receiving device has excessively large power consumption because the receiving device needs to continuously perform blind detection on a channel to determine a moment at which data transmission is started. A specific solution is: obtaining, by a network device, a start location of a first subframe, configuring a first field in downlink control information DCI of a second subframe, and sending, to user equipment, the first subframe and the second subframe that are adjacent to each other, where the first field is used to indicate the start location of the first subframe. The present invention is used for information transmission.

Abstract: A method and an apparatus for transmitting a data subframe are disclosed and relate to the field of mobile communications technologies. In this method, a first device determines a to-be-transmitted data frame, where the to-be-transmitted data frame carries an identifier of an operator to which the first device belongs (100); the first device transmits the to-be-transmitted data frame to a second device (110); and the second device processes, according to the identifier of the operator to which the first device belongs, the data frame transmitted by the first device (210). Because the to-be-transmitted data frame determined by the first device carries the identifier of the operator to which the first device belongs, the first device can accurately perform channel measurement and feedback.
