Abstract: Embodiments of this application provide a channel listening method and apparatus. The method includes: receiving, by a terminal, uplink grant information sent by a base station; determining a first uplink reference resource and a second uplink reference resource based on the uplink grant information; determining a contention window size based on the first uplink reference resource and the second uplink reference resource; and listening to a channel based on the contention window size. According to this technical solution, a real-time channel state can be accurately reflected, so that a probability of a collision between nodes can be reduced, and a channel access opportunity is increased.

Abstract: Embodiments of the present invention provide an uplink information transmission method, a terminal device, and an access network device. The method includes: obtaining, by a terminal device, indication information for sending uplink information on a first symbol set of a target carrier; and sending, by the terminal device, the uplink information in a second time in a time occupied by the first symbol set. The second time is a time in the time occupied by the first symbol set other than a first time, and is a time in which the terminal device is allowed to access a channel of the target carrier to send the uplink information.

Abstract: The present disclosure provides a method and an apparatus for transmitting control data. The method includes: determining, by a terminal device, at least one target cell from at least one unlicensed cell; and transmitting, by the terminal device, control data in the target cell. This can implement transmission of the control data on an unlicensed spectrum resource, so that the control data can be transmitted not merely on a licensed spectrum resource, and communication reliability and user experience can be improved. In addition, this can reduce licensed spectrum resource overheads in a communication process, and increase a capacity of a communications system that has a limited quantity of licensed spectrum resources.

Abstract: The present disclosure relates to example data transmission methods, user equipment, and access network devices in an LAA-LTE system. An example data receiving method includes determining, by user equipment, first information of a first cell. The user equipment determines a first subframe based on the first information, where a downlink data transmission length of the first subframe is less than a first threshold. The user equipment then determines a data transmission characteristic of the cell in the first subframe based on a preset condition, so as to receive, based on the data transmission characteristic, data including the first subframe. In doing so, a data transmission characteristic of a base station or a terminal is standardized, and a reference signal such as a DRS can be correctly identified.

Abstract: Embodiments of the present disclosure provide a data channel sending method. In the method, a base station starts a clear channel assessment (CCA) on a data channel for a to-be-sent data channel. If the CCA on the data channel succeeds, the base station sends the data channel in a first subframe within a time window, where the data channel performs rate matching based on a reference signal (RS). The RS includes a first RS or a second RS. The first RS occupies continuous OFDM symbols in a subframe, and the second RS occupies discontinuous OFDM symbols in a subframe. The time window is a preset time window used to send the first RS, and the first RS is used by a user equipment (UE) to perform cell identification and/or a radio resource management (RRM) measurement on a cell served by the base station.
