A reporting information transmission method performed by a user side device, comprising: determining whether there is a resource conflict between uplink channel resources for carrying at least two pieces of reporting information, the at least two pieces of reporting information at least comprising two of a beam failure recovery request, Synchronization Signal, SS, block-based beam reporting, Channel State Information Reference Signal, CSI-RS-based beam reporting, and Channel State Information, CSI, reporting; and transmitting one or more of the at least two pieces of reporting information, when there is the resource conflict between the uplink channel resources, wherein the at least two pieces of reporting information comprise first reporting information and second reporting information, wherein the transmitting the one or more of the at least two pieces of reporting information comprises: when the uplink channel resource is sufficient to carry the first reporting information and parts of or all of contents in the second reporting information, using the uplink channel resource to carry, and transmit, the first reporting information and parts of or all of the contents in the second reporting information on the premise that the first reporting information is carried by the uplink channel resource, the reporting information transmission method being characterized by the using the uplink channel resource to carry the first reporting information and parts of or all of the contents in the second reporting information comprises: using the uplink channel resource to carry information acquired through jointly encoding the first reporting information and parts of or all of the contents in the second reporting information; or using the uplink channel resource to carry the first reporting information and parts of or all of the contents in the second reporting information in a multiplexing manner. determining whether there is a resource conflict between uplink channel resources for carrying at least two pieces of reporting information, the at least two pieces of reporting information at least comprising two of a beam failure recovery request, Synchronization Signal, SS, block-based beam reporting, Channel State Information Reference Signal, CSI-RS-based beam reporting, and Channel State Information, CSI, reporting;
