MULTIPLE SIGNAL TRANSFORMATION IN WIRELESS RECEIVERS
First Claim
1. A method of wireless communication at a user equipment (UE), comprising:
- tracking a first common offset corresponding to a first group of cells, said first group of cells comprising a serving cell and at least one cell having an offset within a first range of said serving cell;
transforming a plurality of time domain samples into a first plurality of frequency domain symbols using said offset and a first transformation operation assigned to said first group of cells;
tracking a first individual offset of said first plurality of frequency domain symbols for each cell within said first group of cells;
tracking a second common offset corresponding to a second group of cells, said second group of cells comprising at least one cell having an offset within a second range of said serving cell;
transforming said plurality of time domain samples into a second plurality of frequency domain symbols using said second offset and a second transformation operation assigned to said second group of cells; and
tracking a second individual offset of said second plurality of frequency domain symbols for each cell within said second group of cells.

Abstract
A frontend receiver of a user equipment (UE) is configured with multiple transform operations assigned to separate sets of cells. One set of cells includes the serving cell of the UE and at least one additional cell within a first offset range of the serving cell. Another set or sets of cells include additional interferer cells within another offset range of the serving cell. After tracking the common frequency/timing offsets of each set of cells the assigned transform operation for that set transforms the time domain samples into frequency domain symbols. The individual frequency/timing offsets for each cell within the set are then tracked.
