    摘要: A method includes determining a base sequence, cyclic shift, and UE-specific portion of a frequency comb, applying the cyclic shift to the base sequence to create a shifted sequence, and selecting a portion of the shifted sequence as a user equipment-specific SRS. The selected portion of the shifted sequence corresponds to the portion of the frequency comb. A second method includes assigning a cyclic shift and a UE-specific portion of a frequency comb to a UE, where the cyclic shift is for use by the UE to apply the cyclic shift to the determined base sequence to create a shifted sequence. The portion of the frequency comb is for the UE to select a portion of the shifted sequence for SRS. The method includes transmitting indications of the base sequence, the cyclic shift, and the portion of the frequency comb. Auxiliary DMRS may be provided using SRS resources.

    摘要: A method for providing a DM RS arrangement for CoMP reception is described. The method includes receiving (e.g., at a receiver), at a UE, a message for a first CC from a network node. The message includes an indication of a DM RS PUSCH mode for the first CC and a CSI field. The method also includes determining (e.g., at a processor) whether the DM RS PUSCH mode for the first CC includes a mirror cell mode. In response to determining that the DM RS PUSCH mode includes a mirror cell mode, the method includes determining (e.g., at a processor) a DM RS sequence based at least in part on the CSI field. Apparatus and computer readable media are also described.

    摘要: For an integer number R (greater than one) of demodulation reference signal DM RS resources that are reserved for SU-MIMO transmissions by a UE, there is associated in a memory a) for a first transmission instance each of the R DM RS resources with a unique one of R spatial layers or R transmit antennas, and b) for a second transmission instance each of the R DM RS resources with a different unique one of the R spatial layers or transmit antennas. The first and second transmission instances (slots or sub-frames) are consecutive. A UE transmission to a network in the first slot/sub-frame comprises each DM RS resource on the respective spatial layer or transmit antenna with which they are associated for the first slot/sub-frame, and a UE transmission to the network in the first slot/sub-frame comprises each DM RS resource on the respective spatial layer or transmit antenna with which they are associated for the second slot/sub-frame.
