Methods and apparatus for generating, communicating, and/or using information relating to self-noise

摘要

A wireless terminal measures the received power of a tone corresponding to an intention base station null output, measures the received power of pilot signals, and determines a signal to noise ratio of the received pilot signal. The wireless terminal calculates a downlink signal to noise ratio saturation level representative of the SNR of a received downlink signal that the wireless terminal would measure on a received signal transmitted by the base station at infinite power. The calculated downlink signal to noise ratio saturation level is a function of the determined interference power, the measured received pilot signal power, and the determined pilot signal SNR. A report is generated corresponding to one of a plurality of quantized levels, the selected quantized level being the closest representation to the calculated downlink signal to noise ratio saturation level. The generated report is communicated using a dedicated control channel segment in a predetermined uplink timing structure.

1. A method of operating a wireless terminal, the method comprising:
i) measuring received power of a tone corresponding to a NULL base station output; ii) determining, based on the measured power of the tone corresponding to a NULL base station output, a downlink signal to noise ratio saturation level; and iii) operating a transmitter to transmit said determined signal to noise ratio saturation level.
