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: This application provides a communication method and a communication apparatus. A terminal device receives indication information sent by a network device by using higher layer signaling, receives, based on the indication information, a downlink data channel that is sent by the network device and that carries control information, and sends an uplink channel to the network device based on the control information. In this process, a step in which the network device sends a downlink PDCCH to the terminal device and a step in which the network device sends an uplink PDCCH to the terminal device are omitted, and closed-loop service communication is implemented through only one downlink data channel and one uplink channel. There are few signaling-related steps, thereby greatly ensuring service reliability and reducing a latency.

Abstract: The present disclosure relates to methods and apparatus for transmitting uplink control information. One example method includes generating, by a terminal device, an encoded uplink data packet, where the uplink data packet belongs to an uplink channel, the uplink channel is carried on a candidate time-frequency resource in a first time transmission interval (TTI), the candidate time-frequency resource is a first time-frequency resource or a second time-frequency resource, and a second time-domain start point of the second time-frequency resource is later than a first time-domain start point of the first time-frequency resource, performing, by the terminal device, detection on a carrier in which the candidate time-frequency resource is located, and sending, by the terminal device, the uplink channel on the candidate time-frequency resource based on a result of the detection, where the uplink channel includes uplink control information and the encoded uplink data packet.

Abstract: A system and method for transmitting a reference signal in a cell that uses an unlicensed frequency band. The method includes determining a candidate resource set that is used when a first reference signal is transmitted in the cell that uses the unlicensed frequency band, where the candidate resource set includes a preset resource and at least one flexible candidate resource, determining a first candidate resource that is used when the first reference signal is transmitted in the cell that uses the unlicensed frequency band, where a channel on the unlicensed frequency band corresponding to the first candidate resource is in an idle state, and the first candidate resource is the preset resource or a flexible candidate resource in the candidate resource set, and sending the first reference signal on the first candidate resource.
