(57) Abstract :
A method for transmitting an uplink channel sounding reference signal is disclosed in the present invention. The method includes that:
a base station assigns resource to an uplink channel sounding reference signal (SRS) of a UE, and sends the SRS configuration
parameters to the UE, wherein the SRS configuration parameters include an SRS bandwidth parameter BSRS and an SRS frequency
domain position parameter nRRC; after receiving the SRS configuration parameters, the UE calculates the frequency domain starting
position of the SRS of the resource used for sending the SRS according to the SRS configuration parameters, and then sends the SRS
to the base station using the resource; wherein the frequency domain resource assigned to the SRS by the base station corresponds to a
node of a tree structure configured by an SRS bandwidth, and the configured BSRS corresponds to the level on which the node is
located, while the configured nRRC corresponds to the index of a branch node on the lowest level of the node in the tree structure. The
present invention can solve the existing problem that the frequency domain starting position of the SRS can not be determined, which
makes it difficult to perform the uplink channel sounding accurately.
