Also described herein is a carrier medium carrying computer readable code configured to cause one or more processors of a processing system to implement the computer implemented method of determining a power plan/frequency plan combination. The method includes determining candidate power plans for the access points, including determining candidate transmit powers for the access points, determining a candidate frequency plan corresponding to each of the determined candidate power plans using a frequency plan determining method to determine a set of candidate power plan/frequency plan combinations, and rating each combination of a candidate power plan and candidate frequency plan according to an evaluation criterion, and selecting a preliminary power plan/frequency plan combination based on the rating. One embodiment of the method further includes determining a final power plan for the preliminary frequency plan of the preliminary power plan/frequency plan combination to obtain a final power plan/frequency plan combination.

摘要： A method and an apparatus in a first wireless station of a network transmitting to a second wireless station. The network uses multi-tone OFDM signals. The first station includes multiple antennas and a receive and a transmit signal path per antenna. Each receive signal path includes a discrete Fourier transformer determining the tones in a received signal, and each transmit signal path includes an inverse discrete Fourier transformer converting tones to a signal. The method includes determining channel estimates for each tone and each receive path while receiving from the second station, determining transmit weights to transmit to the second station, tone-by-tone weighting a signal for transmission to the second station to produce weighted tone sets for each transmit signal path, and transmitting the weighted tone sets. The first station is configured so that the weighting produces additive beamforming without the second station needing multiple antennas.

摘要： A method, apparatus, and carrier medium for determining channel state information (CSI) in an OFDM radio receiver. The receiver is for receiving packets of OFDM data as a result of OFDM data being transmitted. The method includes forming an estimate of the channels of the subcarriers for received OFDM data to provide frequency responses of the channels of the subcarriers, and forming a measure of quality (“channel state information,” “CSI”) for the channels of the subcarriers based on the relative strength of the frequency responses. The forming of the CSI does not require estimating the relative amount of noise or interference in each channel. The formed CSI is used in demodulating and decoding received OFDM data.
