Abstract: A method and device for reporting scheduling request are provided. The method includes the operations of acquiring a dedicated physical resource of a random access channel (RACH) configured to report a scheduling request, when the scheduling request is triggered, transmitting the RACH on the dedicated physical resource. The dedicated physical resource includes a plurality of periodic physical resources. Through this dedicated physical resource, the user equipment (UE) can report scheduling request in a contention-free random access way, and the capacity of a preamble sequence is improved and inter-cell interference is reduced.
