Abstract: Embodiments relate to a data transmission method and device. A feedback request is sent by a first device to user equipment that instructs the user equipment to feed back channel indication data to a network device. The channel indication data indicates that a channel is occupied by the first device within a time that corresponds to the channel indication data. The network device includes the first device and one additional device. The first device receives the channel indication data sent by the UE. The first device performs data transmission with the UE using the channel within the time that corresponds to the channel indication data.

Abstract: A random access method and apparatus to increase an opportunity of performing physical random access channel (PRACH) access, where the method includes receiving, by a terminal, information about a PRACH time window from a base station, where the information about the PRACH time window carries a size of the PRACH time window, preempting, by the terminal, an unlicensed carrier on which a PRACH resource is configured, and performing, by the terminal before the size of the PRACH time window is exceeded, .PRACH access on the successfully preempted unlicensed carrier on which the PRACH resource is configured. Therefore, by configuring the PRACH time window, the terminal has more opportunities to preempt the unlicensed carrier on which the PRACH resource is configured, greatly improving a PRACH access success rate.

Abstract: A multi-link configuration method, a base station, and a user equipment, where the UE generates uplink information and sends the uplink information to the base station. The base station configures a first set or a second set for the UE based on the uplink information. In this process, the transmission point included in the first set is a candidate transmission point, and the transmission point included in the second set establishes a plurality of links to a user, and is a transmission point that actually transmits data to the UE. When a signal of the transmission point included in the second set is weak or interrupted, a transmission point with good quality is selected from the first set and added to the second set to reduce a quantity of times of link interruption and service interruption.

Abstract: An interference indication method and apparatus are presented. After detecting interference from a neighboring cell, a base station sends interference indication information to the neighboring cell, where the interference indication information includes at least indication information of a frequency resource that receives the interference from the neighboring cell and that is configured to be in a flexible half-duplex mode, so as to indicate that the interference from the neighboring cell is interference on the frequency resource configured to be in the flexible half-duplex mode. In this way, in an application scenario of a flexible half-duplex technology, a base station can learn of a status of interference from a neighboring cell, so as to use a corresponding interference suppression mechanism.
