Patent

CA 2694731

Systems and methodologies are described that facilitate encoding feedback or control information into a compact payload. In particular, a rank indicator, a precoding matrix indicator and channel quality indicators are packaged into a control channel payload that fits into a single sub-frame. The payload format is determined based at least in part on an antenna configuration or channel quality indicator granularity. In addition, hybrid automatic repeat requests can be included in the payload.

L'invention concerne des systèmes et des méthodologies qui facilitent le codage d'informations de retour ou de commande dans des données utiles compactes. En particulier, un indicateur de rang, un indicateur de matrice de précodage et des indicateurs de qualité de canal sont intégrés dans des données utiles de canal de commande qui s'ajustent à une sous-trame unique. Le format de données utiles est déterminé sur la base, au moins en partie, d'une configuration d'antenne ou d'une granularité d'indicateur de qualité de canal. De plus, les requêtes de répétition automatiques hybrides peuvent être comprises dans les données utiles.
