Method for allocating multi-UEs' sounding reference signal (SRS) uplink resources and eNB

摘要

The present invention is to provide a method for allocating multi-UEs' Sounding Reference Signal (SRS) uplink resources, and an eNB for allocating multi-UEs' SRS uplink resources with the method. The method may automatically and dynamically allocate multi-UEs' SRS resource in both the time domain resource and the frequency domain resource in accordance with system capacity attribute value and configured SRS transmission period. When multi-UEs' SRS are positioned in the same time domain resource and same frequency domain resource, it is also possible to further divide the multi-UEs' SRS automatically by a method of configuring cyclic shift. According to the method of the present invention, the eNB may allocate SRS resources for multi-UEs more flexibly and effectively, which reduces disturbance to multi-UEs' SRS, improves the decoding performance of physical layer, and thus improves the stability of a system.
