Embodiments of this application disclose a hybrid bonding structure and a hybrid bonding method. The hybrid bonding structure includes a first chip and a second chip. A surface of the first chip includes a first insulation dielectric and a first metal, and a first gap area exists between the first metal and the first insulation dielectric. A surface of the second chip includes a second insulation dielectric and a second metal. A surface of the first metal is higher than a surface of the first insulation dielectric. Metallic bonding is formed after the first metal is in contact with the second metal, and the first metal is longitudinally and transversely deformed in the first gap area. Insulation dielectric bonding is formed after the first insulation dielectric is in contact with the second insulation dielectric.

Embodiments of the present disclosure disclose a method for base station backhaul, a related device and a system for base station backhaul. The method for base station backhaul includes: modulating data carried on at least two channels to corresponding subcarriers respectively, combining and modulating the subcarriers to a first OFDM signal, sending a first broadband OFDM signal to a remote radio unit, sending, by the remote radio unit, the first broadband OFDM signal to an antenna port after splitting and filtering the same; receiving a second broadband OFDM signal sent by the remote radio unit, demodulating subcarriers included in the second broadband OFDM signal, and sending data obtained by demodulating to corresponding channels respectively. By adopting the present disclosure, a utilization rate of a link channel may be improved, and high-capacity base station backhaul may be achieved under a low cost condition.
