Abstract
Official abstract text for this publication.
Methods, a user equipment and a radio network node relating to estimation of a channel quality indicator, CQI, are provided. A first reference signal is carried by a downlink channel of a radio communication system. The user equipment receives from the radio network node information about scheduling of a downlink transmission to the user equipment and information about a second reference signal being different from the first reference signal. Furthermore, the user equipment receives from the radio network node the downlink transmission. The downlink transmission comprises the first reference signal and the second reference signal. Next, the user equipment estimates the CQI based on the first reference signal and the second reference signal.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method in a user equipment for estimating a channel quality indicator, CQI, wherein the user equipment and a radio network node are comprised in a radio communication system, wherein a first reference signal is carried by a downlink channel of the radio communication system, wherein the method comprises: receiving from the radio network node, information about scheduling of a downlink transmission to the user equipment, and information about a second…
