摘要： A cyclic shift of a reference signal is quantized as a combination of a cell specific cyclic shift with an outcome of a pseudo-random hopping, and an indication of the cell specific cyclic shift is broadcast in the cell. In one embodiment the cyclic shift is quantized as a modulo operation on a sum of the cell specific cyclic shift, the outcome of the pseudo-random hopping, and a user specific cyclic shift, in which case an indication of the user specific cyclic shift is sent in an uplink resource allocation and a user sends its cyclically shifted reference signal in the uplink resource allocated by the uplink resource allocation. The cyclic shift may also be quantized according to length of the reference signal as cyclic_shift_symbol=(cyclic_shift_value*length of the reference signal)/12; where cyclic_shift_value is between zero and eleven and cyclic_shift_symbol is the amount of cyclic shift given in reference signal symbols.

摘要： The present invention relates to a method and system for providing a downlink connection in a cellular network. A feedback information indicating a selected cell is transmitted to a central network element (20) controlling at least two network elements (N1–N3) serving cells (C1–C3) of the cellular network. The at least two network elements are controlled by the central network element based on the feedback information so as to establish the downlink connection. Thus, the downlink transmissions of the non-central network elements (N1–N3) are controlled by the network so as to decrease performance loss due to reception errors of the feedback information. The feedback information may be a temporary ID obtained in a site selection diversity transmission control scheme.
