Abstract: The present application relates to a base station, user equipment, and an adaptive retransmission method. The base station includes a sending unit, configured to send a data packet to user equipment by using a radio resource on a first frequency band, The base station also includes a receiving unit, configured to receive feedback information sent by the user equipment, where the feedback information is used to indicate whether the data packet is successfully sent. The sending unit is further configured to, if the feedback information indicates that the data packet fails to be sent, send the data packet to the user equipment by using a radio resource on a second frequency band. The first frequency band and the second frequency band have an overlapping coverage area, and the user equipment is within the overlapping coverage area.

Abstract: A network-side device, user equipment, and method for blind area management. The network-side device includes a receiving module configured to receive measurement information sent by user equipment, a processor, and a non-transitory computer-readable storage medium storing a program to be executed by the processor. The program includes instructions to identify a status of the user equipment according to the measurement information received from the user equipment, wherein the status of the user equipment is a normal communication state or a blind area state, and the blind area state includes at least one of a beam biased state, an interfered state, or a blocked state, and perform blind area management of the user equipment when the user equipment is in the blind area state.

Abstract: The present invention relates to a data transmission method and a base station, the method includes: determining, by a base station according to channel state information CSI, a transmission path for forwarding first data to a first terminal, where if the base station determines that the first data needs to be forwarded by at least one small cell to the first terminal, the transmission path includes a path from the base station to a small cell and a path from the small cell to the first terminal; and sending, by the base station according to the transmission path, a first data frame to the first terminal via the at least one small cell. In the present invention, a macro base station performs centralized scheduling, and performs unified encapsulation according to a scheduled transmission path, thereby effectively simplifying processing by a forwarding node and reducing a delay.
