Title:
METHOD AND APPARATUS FOR OBTAINING CQI AND METHOD FOR MAPPING SINR INTO CQI
Document Type and Number:
WIPO Patent Application WO/2008/098524
Kind Code:
A1
Abstract:
A method and an apparatus are used for obtaining CQI that includes a transport block
set and a modulating manner, and a method is used for mapping SINR into coding rate.
The method for obtaining CQI includes that the mapping relation between stored
SINR and coding rate is inquired according to the obtained SINR, and the modulating
manner and the coding rate are determined; after the number of bits capable of
being carried is determined according to the physical resource and modulating
manner, the product of the number of bits capable of being carried and the coding
rate is set as transport block set. The mapping relation is a mapping curve including
a point of switch, and low modulation level curve is selected below the SINR value
corresponding to the point of switch, and high modulation level curve is selected
above the SINR value corresponding to the point of switch.
