Patent ID: 8873362

Claim:
A method for assigning information related to a Demodulation (DM) Reference Signal (RS) associated with transmission of Physical Uplink Shared Channel (PUSCH) or Physical Uplink Control Channel (PUCCH) in a communication system, wherein a Base Station (BS) transmits in Physical Downlink Control Channels (PDCCHs) a respective set of Downlink Control Information (DCI) formats to a plurality of UEs, the method comprising the steps of: indicating, by the BS, through an RS Configuration (RSC) Information Element (IE) included in a first DCI format from a subset of a set of DCI formats, a first Cyclic Shift (CS) and a first Orthogonal Cover Code (OCC) for the first RS transmission by the first UE; and indicating, by the BS, through an RSC IE in a second DCI format from a subset of the set of DCI formats, a second CS and a second OCC for the second RS transmission by the second UE, wherein each DCI format from a subset of the set of DCI formats includes IEs configuring data and RS transmissions from the plurality of UEs to the BS, and the IEs include an RSC IE for an RS transmission by a UE.
