Claim of US Patent No. 10,117,254

1. A method of wireless communication for an access point, comprising:determining a first plurality of resource units for communication of a first data symbol;
determining a second plurality of resource units for communication of a second data symbol, wherein the second data symbol is subsequent to the first data symbol;
generating a first set of pilot signals in at least one resource unit of the first plurality of resource units, wherein generating the first set of pilot signals in the at least one resource unit of the first plurality of resource units comprises: determining pilot tone locations associated with the at least one resource unit of the first plurality of resource units, and determining an initial pilot sequence associated with the determined pilot tone locations;
generating a second set of pilot signals in at least one resource unit of the second plurality of resource units, wherein generating the second set of pilot signals in the at least one resource unit of the second plurality of resource units comprises: determining a second pilot sequence by shifting the initial pilot sequence; and
transmitting the generated first set of pilot signals in the at least one resource unit of the first plurality of resource units and the generated second set of pilot signals in the at least one resource unit of the second plurality of resource units.
