Title
(EN) PDCCH DESIGN FOR NARROWBAND DEPLOYMENT
(FR) CONCEPTION DE PDCCH POUR DÉPLOIEMENT EN BANDE ÉTROITE
Abstract
(EN)
Narrowband Physical Downlink Control Channel (PDCCH) implementations are discussed. An example Evolved NodeB (eNB) comprises a memory storing instructions, a processor configured to execute the instructions, and a transmitter circuit. The processor is configured to determine at least one of downlink or uplink scheduling for one or more machine-type communication (MTC)-enabled user equipments (UEs); to generate, based at least in part on the determined scheduling, one or more MTC- physical downlink control channel (PDCCH) signals (M-PDCCH signals) associated with the one or more MTC-enabled UEs; and to perform channel coding, multiplexing, and scrambling of the one or more M-PDCCH signals. The transmitter circuit is configured to map the one or more M-PDCCH signals to resource element groups (REGs) in order of increasing subcarrier followed by orthogonal frequency division multiplexing (OFDM) symbol and to transmit the one or more M-PDCCH signals via a narrowband bandwidth of less than 1.4 MHz.

L'invention concerne des modes de réalisation de canaux physiques de commande de liaison descendante (PDCCH) en bande étroite. Un nœud B évolué (eNB) décrit à titre d'exemple comporte une mémoire conservant des instructions, un processeur configuré pour exécuter les instructions et un circuit d'émetteur. Le processeur est configuré pour déterminer au moins une programmation de liaison descendante ou liaison montante pour un ou plusieurs équipements d'utilisateurs (UE) aptes à une communication de type machine (MTC); pour générer, en se basant au moins en partie sur la programmation déterminée, un ou plusieurs signaux de canaux physiques de commande de liaison descendante (PDCCH) de MTC (signaux M-PDCCH) associés au(x) UE aptes à la MTC; et pour effectuer un codage de canaux, un multiplexage et un embrouillage du ou des signaux M-PDCCH. Le circuit d'émetteur est configuré pour faire correspondre le ou les signaux M-PDCCH à des groupes d'éléments de ressources (REG) par ordre de sous-porteuse croissante suivis par un symbole de multiplexage avec répartition orthogonale en fréquence (MROF) et pour envoyer le ou les signaux M-PDCCH via une largeur de bande en bande étroite de moins de 1,4 MHz.
