Methods and arrangements for frequency selective transmission

An apparatus for frequency selective transmission, the apparatus comprising:

• logic to determine a set of sub-channels of a wide bandwidth channel to transmit sounding packets based upon information about the sub-channels;
• transmit sounding packets wirelessly on the set of sub-channels of the wide bandwidth channel;
• receive a selection of a sub-channel of the set of sub-channels from a receiving communications device;
• and communicate with the receiving communications device via the sub-channel;
• and
• a physical layer in communication with the logic to transmit the packets.

A program product for frequency selective transmission, the program product comprising:

• a storage medium comprising instructions to be executed by a processor-based device, wherein the instructions, when executed by the processor-based device, perform operations, the operations comprising:
• determining a set of sub-channels of a wide bandwidth channel to transmit sounding packets based upon information about the sub-channels;
• transmitting sounding packets wirelessly on the set of sub-channels of the wide bandwidth channel;
• receiving a selection of a sub-channel of the set of sub-channels from a receiving communications device;
• and
• communicating with the receiving communications device via the sub-channel.

A method for frequency selective transmission, the method comprising:

• receiving, by a first communications device, sounding packets wirelessly on a subset of sub-channels of the wide bandwidth channel during a beacon interval;
• determining, by the first communications device, a selected sub-channel from the subset of the sub-channels on which a sounding packet is received by the first communications device during the beacon interval;
• and
• communicating, by the first communications device, with a second communications device via the selected sub-channel.
