Abstract
A system and a method for allocating Sounding Reference Signal (SRS) resources are provided in the present invention, the method includes: an e-Node-B (eNB) allocating a SRS bandwidth with 4n Resource Blocks (RBs) to a terminal, and equally dividing a time domain sequence of a SRS into t portions in the SRS bandwidth; the eNB configuring a time domain RePetition Factor (RPF) used by the UE, and the eNB configuring the UE to use one or more cyclic shifts in L cyclic shifts for each UE; then the eNB notifying the UE of a value of the time domain RPF, a location of a used frequency comb and a used cyclic shift by signaling, wherein n is a positive integer; the RPF satisfies a following condition:can be exactly divided by 12; t is an integer by whichcan be exactly divided; and L≦t.
