Frame formatting for communications within single user, multiple user, multiple access, and/or MIMO wireless communications

摘要

Frame formatting for communications within single user, multiple user, multiple access, and/or MIMO wireless communications. A signal is processed within a communication device using at least two respective downclocking ratios (e.g., a first downclocking ratio applied to a first portion of the signal such as a frame or packet extracted there from, a second downclocking ratio applied to a second portion of the signal). Alternatively, a signal is divided into more than two respective portions, and different respective downclocking ratios are applied to those different respective portions (e.g., a first downclocking ratio applied to a first portion of the signal, and so on up to an n-th downclocking ratio applied to an n-th portion of the signal). Some implementations apply a singular or common downclocking ratio to more than one portion of the signal (which may be contiguous/adjacent or non-contiguous/non-adjacent within the signal).

1. A wireless communication device comprising:
a processor configured to:
receive a signal from another wireless communication device via a communication channel having a channel bandwidth;process a first at least one orthogonal frequency division multiplexing (OFDM) symbol of an OFDM packet of the signal based on a first clock signal;downclock the first clock signal using a downclocking factor to generate a second clock signal; andprocess a second at least one OFDM symbol of the OFDM packet based on the second clock signal to extend OFDM symbol duration of the second at least one OFDM symbol of the OFDM packet.
