When the down control channel includes the demodulated reference signal of different terminals, and the demodulated reference signal of different terminals When using code division multiplexing mode to be multiplexed in time domain or frequency domain, the demodulated reference signal category that is multiplexed using same group of orthogonal code In same control group or same benchmark group.

As shown in Figure 11 A~11E, down control channel supports multiuser multiplexing using CDM mode.Pass through frequency domain/time domain Two adjacent RE distinguish different ports using different OCC.In order not to destroy the orthogonal performance of OCC, according to example When mode in 1/2/3/4 is grouped the DMRS symbol of down control channel, need to be divided by basic unit of OCC Group carries out with the DMRS on two RE of covering of group OCC or simultaneously phase rotation or simultaneously without phase rotation. The RE in dotted line frame in such as figure needs to be divided to same group, such as control group, to carry out phase rotation.

Example 5-1: phase rotation value is 0 or π.Wherein, phase rotation 0 indicates that transmitted bit 0, phase rotation π indicate to pass Defeated bit 1.The program transmits 1 bit information using reference signal phase rotation in each down control channel.

Example 5-2: phase rotation value 0, pi/2, π, 3 pi/2s.Wherein, phase rotation 0 indicates transmitted bit 00, phase rotation Turning pi/2 indicates that transmitted bit 01, phase rotation π indicate that transmitted bit 11,3 pi/2 of phase rotation indicate transmitted bit 10.The program 2 bit informations are transmitted using reference signal phase rotation in each down control channel.
