The method of allocating the bandwidth of an uplink sounding reference signal and means

The method for allocating uplink sounding reference signal bandwidth, comprising the steps of: determining a current level of a sounding reference signal according to the scheduling of bandwidth SRS bandwidth; determining a current SRS bandwidth level corresponding to the SRS transmission power margin; using the SRS transmit power margin determines whether the current whether a bandwidth corresponding to bandwidth class power limited; if so, a decline in the SRS transmission bandwidth level to redefine power margin; otherwise, the user terminal is assigned bandwidth level corresponding to the current bandwidth. Embodiments of the present invention further provides an apparatus for uplink sounding reference signal bandwidth allocation. The method and apparatus of the embodiments of the present invention enables more rational allocation of bandwidth SRS, and may improve the accuracy of channel sounding, thereby improving scheduling performance of the entire system.
