Abstract:
1. A method for generating a reference signal, comprising: obtaining first control information, wherein the first control information indicates or comprises cyclic shift related information which is used to control an offset value of cyclic shifts in two timeslots of a same transmission time interval (TTI); and sending the first control information to a terminal belonging to the serving cell, so that the terminal belonging to the serving cell generates the reference signal according to the cyclic shift related information which is indicated or comprised by the first control information and used by the terminal to send the reference signal, wherein a variation rule of a cyclic shift which the terminal belonging to the serving cell uses to generate the reference signal is the same as that of a cyclic shift which a terminal belonging to a coordinated cell uses to generate a reference signal, and the cyclic shift which the terminal belonging to the serving cell uses to generate the reference signal is different from the cyclic shift which the terminal belonging to the coordinated cell uses to generate the reference signal; sending orthogonal cover code (OCC) information to the terminal belonging to the serving cell, the OCC information is used to superpose an orthogonal cover code on the reference signals in a same TTI, wherein, the OCC allocated to the terminal belonging to the serving cell is different from an OCC allocated to the terminal belonging to the coordinated cell.
