Patent ID: 8660077

Claim:
A method implemented in a base station for conveying scheduling information in an orthogonal frequency division multiple access (OFDMA) multi-user (MU)-multiple input multiple output (MIMO) system, the method comprising: transmitting to a user equipment (UE) the scheduling information for the UE in a transmission with MU-MIMO, wherein the scheduling information includes a resource block (RB) assigned to the UE, the number of streams, and an indication of a plurality of dedicated reference symbol (RS) layers assigned to the UE, wherein the dedicated RS layers have consecutive indices, wherein the scheduling information further includes at least one of modulation constellation of the UE, a coding rate of the UE, a precoder matrix index (PMI) of the UE, and a transmit power value of the UE, wherein at least one of the PMI and the transmit power value is transmitted to the UE using dedicated reference symbol (RS) layers, and wherein each of the dedicated RS layers is precoded with a precoder and is transmitted on a portion of an RB.
