PROBLEM TO BE SOLVED: To provide techniques to manage dwell times for pilot rotation.SOLUTION: An apparatus comprises a memory 188 configured to store a data structure with a set of modulation and coding schemes (MCS) available to an orthogonal frequency division multiplexing (OFDM) system, having associated pilot dwell times. The apparatus further comprises a processor circuit 186 coupled to the memory, the processor circuit configured to identify an MCS to communicate a packet using multiple subcarriers of the OFDM system, and retrieve a pilot dwell time associated with the MCS from the memory, the pilot dwell time indicating when to shift a pilot tone between subcarriers of the multiple subcarriers during communication of the packet.SELECTED DRAWING: Figure 1B |
