Channel quality reporting using a dynamically adjusted measurement power offset

摘要

Methods and apparatuses are provided for facilitating dynamic measurement power offset adjustments for use in reporting channel quality feedback. A user equipment may generate and send a plurality of channel quality indicator (CQI) values to a base station. The base station determines whether at least some of the received CQI values are outside of an upper or lower threshold value. If at least some of the received CQI values are outside the upper or lower threshold value, the base station can transmit an adjusted measurement power offset to the user equipment. On receipt of the adjusted measurement power offset, the user equipment generates subsequent CQI values using the adjusted measurement power offset.

1. A method of wireless communication, comprising:
transmitting a plurality of channel quality indicator values to a base station for determining a distribution relating to the plurality of channel quality indicator values; receiving a transmission from the base station providing a new measurement power offset based on the distribution in response to detecting at least a portion of the plurality of channel quality indicator values transmitted to the base station being clipped at or above an upper threshold value of a selected range, or being clipped at or below a lower threshold value of the selected range, the new measurement power offset adjusting a previous measurement power offset by an amount calculated to at least center the distribution of the plurality of channel quality indicator values within the selected range; and employing the new measurement power offset in determining a plurality of subsequent channel quality indicator values.
