Title
(EN) EVOLVED NODE B CHANNEL QUALITY INDICATOR (CQI) PROCESSING FOR HETEROGENEOUS NETWORKS
(FR) TRAITEMENT D'INDICATEUR DE QUALITÉ DE CANAL (CQI) DE NOEUD B ÉVOLUÉ POUR DES RÉSEAUX HÉTÉROGÈNES
Abstract
(EN) Methods and apparatus for processing channel quality information (CQI) and scheduling resources subject to cooperative resource allocation based on the CQI are provided. To convey the CQI for protected/unprotected subframes in a single report, a new vector CQI format may be utilized. Two alternatives for CQI processing this vector format and the advantages of each are described. In the first alternative, a single entry from the CQI vector is selected for processing by a downlink scheduler and/or other media access control (MAC) blocks (e.g., a PHICH, DCI power control, and/or PDCCH scheduler). In the second alternative, the selection from the CQI vector is made on a per-subframe basis, and both the subframe and the selected CQI element are processed by the downlink scheduler and/or the other MAC blocks. In this manner, better scheduling decisions may be made using the CQI vector.
(FR) Des procédés et un appareil permettant de traiter des informations de qualité de canal (CQI) et des ressources de planification sujettes à une allocation de ressource coopérative basée sur le CQI sont fournis. Pour transporter le CQI pour des sous-trames protégées/non protégées dans un seul rapport, un nouveau format CQI vectoriel peut être utilisé. Deux alternatives pour traiter CQI ce format vectoriel et les avantages liés à chacune d'elles sont décrits. Dans la première alternative, une seule entrée du vecteur CQI est sélectionnée pour un traitement par un ordonnanceur de liaison descendante et/ou d'autres blocs de contrôle d'accès au support (MAC) (par exemple, un PHICH, un régulateur de puissance DCI, et/ou un ordonnanceur PDCCH). Dans la deuxième alternative, la sélection à partir du vecteur CQI est effectuée sur une base sous-trame par sous-trame, et la sous-trame et l'élément CQI sélectionné sont tous deux traités par l'ordonnanceur de liaison descendante et/ou les autres blocs MAC. De cette manière, des décisions d'ordonnancement plus adaptées peuvent être prises en utilisant le vecteur CQI.
