Pilot symbol patterns for transmission through a plurality of antennas

A user equipment device (UE) comprising:

• one or more receive antennas;
• and
• a processor, wherein the processor is configured to receive transmissions via the one or more receive antennas, wherein the UE is configured to:
• receive, via the one or more receive antennas, a signal including four antenna scattered pilot symbol patterns in a plurality of time intervals and a plurality of subcarriers in frequency, wherein each time interval of the plurality of time intervals spans seven orthogonal frequency division multiplexing (OFDM) symbol durations in time, wherein a first and second antenna scattered pilot symbol patterns of the four antenna scattered pilot symbol patterns are identical versions of each other shifted in frequency, wherein a third and fourth antenna scattered pilot symbol patterns of the four antenna scattered pilot symbol patterns are identical patterns shifted in frequency, wherein the first and third antenna scattered pilot symbol patterns are not shifted versions of each other, wherein the four antenna scattered pilot symbol patterns are mapped to pilot symbol positions on exactly three of the seven OFDM symbols of each time interval of the plurality of time intervals, and wherein a repetition of each of the four antenna scattered pilot symbol patterns are received in each interval of the plurality of time intervals.
