A resource mapping location determination method performed by user equipment and comprises: obtaining first information, wherein the first information is used to indicate a cyclic shift start resource block location or a cyclic shift end resource block location for resource mapping in a resource block cyclic shift manner in a bandwidth used by the user equipment; using the location indicated by the first information as a start location or an end location for numbering resource blocks in the bandwidth used by the user equipment, and numbering, according to the resource block cyclic shift manner, the resource blocks in the bandwidth used by the user equipment; determining, according to the resource block cyclic shift manner and the first information, a resource mapping location of a first channel or a first signal in the bandwidth used by the user equipment; and receiving or sending the first channel or the first signal at the resource mapping location; wherein the determining, according to the resource block cyclic shift manner and the first information, a resource mapping location of a first channel or a first signal in the bandwidth used by the user equipment comprises: determining, according to the numbered resource blocks and the resource block cyclic shift manner, the resource mapping location of the first channel or the first signal in the bandwidth used by equipment; said method characterised in that the obtaining first information comprises: blindly detecting a second signal in order to determine the first information according to a start location or an end location of the second signal in the bandwidth used by the user equipment, wherein the start location or the end location of the second signal in the bandwidth used by the user equipment is a start location or an end location of a bandwidth corresponding to a sequence of the second signal, a size of the bandwidth corresponding to the sequence of the second signal is predefined or is notified by a base station or blindly detected, and the bandwidth corresponding to the sequence of the second signal is a transmission bandwidth or a carrier bandwidth of the second signal. obtaining first information, wherein the first information is used to indicate a cyclic shift start resource block location or a cyclic shift end resource block location for resource mapping in a resource block cyclic shift manner in a bandwidth used by the user equipment;
