Claim of US Patent No. 11,032,801

1. A mobile station served by a base station using Orthogonal Frequency Division Multiplexing (OFDM) and utilizing time slots in a time domain and subchannels in a frequency domain, the mobile station comprising:a transmitter; and
a receiver configured to:
receive a control message from the base station over at least one control channel; and
receive and process a forward link transmission based on the control message in one of the time slots, wherein the forward link transmission includes pilots;
wherein the control message includes: information indicating subcarriers for the forward link transmission, spatial information for the forward link transmission, pilot information for the forward link transmission, and information indicating a modulation and coding scheme used for the forward link transmission, and further wherein the pilot information indicates a number of symbols used for the pilots and a location of the pilots in time and frequency.
