    Abstract: A data retransmission method includes transmitting, by a first device, data to a second device by using a first carrier. The first carrier is an unlicensed carrier. The method additionally includes retransmitting, by the first device, the data to the second device by using a second carrier. The first carrier and the second carrier are different carriers. The method additionally includes sending, by the first device, control signaling to the second device. The control signaling is used to indicate the data.

    Abstract: A method for transmitting hybrid automatic repeat request (HARQ) acknowledgement information and a device to provide a manner of performing HARQ feedback in a Licensed Assisted Access-Long Term Evolution (LAA-LTE) system. The method for transmitting HARQ acknowledgement information includes sending, by a network device, first information to user equipment, where the first information indicates a subframe to be used by the user equipment to send the HARQ acknowledgement information to the network device on an unlicensed carrier, and receiving, by the network device in the subframe indicated by the first information, the HARQ acknowledgement information from the user equipment.

    Abstract: A radio communications method, a base station, and a terminal, where the base station sends downlink control information to the terminal, where the downlink control information includes uplink scheduling indication information, and the uplink scheduling indication information instructing the terminal to send uplink data in a plurality of uplink sub frames on at least one unlicensed carrier, such that the terminal sends uplink data in a plurality of uplink subframes on one or more corresponding unlicensed carriers based on the uplink scheduling indication information, thereby implementing scheduling, using uplink scheduling indication information in one piece of downlink control information, of a plurality of uplink subframes to perform uplink transmission. This increases a data volume in data transmission while effectively reducing scheduling signaling overheads.

    Abstract: Embodiments provide a method and an apparatus for transmitting a channel state information-reference signal (CSI-RS). The method includes: determining, by a base station based on one physical resource block (PRB) pair, a first configuration mode used for a CSI-RS, where a resource element (RE) occupied in the first configuration mode is obtained by aggregating all or a part of resource elements REs occupied in at least two second configuration modes used for the CSI-RS. The first configuration mode is a configuration mode for more than eight CSI-RS ports, and includes a correspondence between each CSI-RS port and a resource element RE. The second configuration mode is a configuration mode for eight CSI-RS ports, and comprises a correspondence between each CSI-RS port and a resource element RE. The method also includes transmitting, by the base station, the CSI-RS to user equipment using the first configuration mode.

    Abstract: A subframe scheduling method and a base station are disclosed. The method is applied to the base station and includes: when preempting an unlicensed carrier, obtaining, by the base station, a starting position of the preempted unlicensed carrier; determining a first number and a type of a first subframe based on the starting position, where the first number is a symbol number corresponding to the starting position that is used by the base station to send data, and the first subframe is a subframe in which a symbol corresponding to the first number is located; and sending the type of the first subframe and the first number to a terminal. In embodiments of the present invention, a processing process of the terminal can be simplified.

    Abstract: A data sending method includes determining, by user equipment, a narrowband time-frequency resource scheduled by a base station. The method further includes performing, by the user equipment, clear channel assessment CCA channel detection on the narrowband time-frequency resource to obtain a channel energy value of the narrowband time-frequency resource. The method further includes determining, by the user equipment, whether the channel energy value is less than a preset energy threshold. When the channel energy value is less than the preset energy threshold, the method includes sending, by the user equipment, uplink data to the base station on the narrowband time-frequency resource.
