摘要：
Technology for user equipment (UE)-specific assigning of demodulation reference signal (DM-RS) sequences to support uplink (UL) coordinated multipoint (CoMP) is disclosed. One method can include a DM-RS sequence assignment device sorting the plurality of UE into a list according to a number of reception point (RP) links for each UE in a CoMP set, and assigning a base DM-RS sequence and a cyclic shift (CS) to a top-ranked UE from the list. The top-ranked UE can have a highest number of RP links. The DM-RS sequence assignment device can repeatedly assign a different CS of the base DM-RS sequence to a plurality of unassigned UE in a same cell as the top-ranked UE, and repeatedly assign the different CS of the base DM-RS sequence to a plurality of unassigned UE in a cooperatively served cell of the top-ranked UE.
