AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 53-56, 64-66, 70, 76, 81-84 and 87-94 is confirmed.
Claims 1-52, 57-63, 67-69, 71-75, 77-80, 85, 86, 95 and 96 were not reexamined.
[ 53. A method for managing interference in a radio communications network, comprising the steps of:
receiving at a first node in the radio communications network an instruction transmitted from a second node in the radio communications network to avoid using a plurality of frequencies to transmit to the second node;
filtering a transmission signal to remove power from the transmission signal at each frequency in the plurality of frequencies to be avoided;
transmitting the filtered transmission signal to the second node;
receiving a compressed first feedback from the second node that characterizes receipt of a first signal sent from the first node to the second node;
receiving a compressed second feedback from a third node that characterizes receipt of a second signal sent from the first node to the third node;
decompressing the compressed first feedback resulting in a decompressed first feedback; and
decompressing the compressed second feedback resulting in a decompressed second feedback;
wherein the filtered transmission signal is a filtered first transmission signal that is transmitted to the second node using an 802.11-based orthogonal frequency-division multiplexing (OFDM) protocol via at least one antenna of a plurality of antennas, using a first power that is based on the decompressed first feedback; and further comprising:
transmitting, using the 802.11-based OFDM protocol, a filtered second transmission signal, simultaneously with the filtered first transmission signal, to the third node using a second power that is based on the decompressed second feedback.]
