The invention discloses an uplink scheduling request resource allocation method and an uplink scheduling request resource allocation device applied to fast scheduling. The method comprises the following steps: generating eight orthogonal codes for a SR uplink scheduling request position resource of an uplink frame; newly adding at least one partially orthogonal code based on the weight orthogonalcodes; allocating the newly added partially orthogonal code as a SR code resource applied to fast scheduling. By application of the method and the device provided by the invention, fast scheduling average access time length of UE can be reduced, and access efficiency can be improved.
