Channel Quality Index Determination

摘要

A method of a transceiver arranged to operate in a cellular communication system comprising cells is disclosed. The method comprises receiving a transmission from a first cell; determining an interfering signal and its occupation in time and/or frequency; determining reduced values in the received signal corresponding to the occupation in time and/or frequency of the interfering signal; and measuring a quotient between desired signal and non-desired signal of reference symbols of the received signal. A channel quality index, CQI, is formed taking into account reduction of values performed at the reducing, and the CQI is reported to the communication system. A transceiver and computer program for the same are also disclosed.

1. A method of a transceiver arranged to operate in a cellular communication system comprising cells, the method comprising
receiving a signal transmitted from a first cell; determining an interfering signal and its occupation in time and/or frequency, wherein the interfering signal comprises one or more reference symbols transmitted from a second cell in respective resource elements of an almost blank subframe; reducing soft bit values for bits of one or more received symbols in the received signal corresponding to the occupation in time and/or frequency of the reference symbols in the interfering signal to obtain reduced values for the bits of the received symbols; measuring a quotient indicative of a signal quality of the received signal; forming a channel quality index, CQI, based on the measured quotient and the reduced values; and reporting the CQI to the communication system.
