TECHNIQUES TO MANAGE DWELL TIMES FOR PILOT ROTATION

摘要

Techniques to manage dwell times for pilot rotation are described. An apparatus may comprise a memory configured to store a data structure with a set of modulation and coding schemes (MCS) available to an orthogonal frequency division multiplexing (OFDM) system, each MCS having an associated pilot dwell time. The apparatus may further comprise a processor circuit coupled to the memory, the processor circuit configured to identify a 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 to indicate when to shift a pilot tone between subcarriers of the multiple subcarriers during communication of the packet. Other embodiments are described and claimed.

1. An apparatus configured to communicate orthogonal frequency division multiplexing (OFDM) wireless communications, the apparatus comprising:
a processor circuit configured to vary, in a non-sequential manner, positions of first and second pilot tones between a plurality of symbols of a packet, a symbol of the plurality of symbols comprising a first set of subcarriers and a second set of subcarriers after the first set of subcarriers, said processor circuit is configured to set the first pilot tone to subcarriers within the first set of subcarriers and to set the second pilot tone to subcarriers within the second set of subcarriers, while maintaining a predefined constant spacing between the first and second pilot tones; and a transceiver to transmit an electromagnetic representation of the packet.
