(EN) IMPROVED EARLY DETERMINATION IN HIGH-SPEED SHARED CONTROL CHANNEL DECODING
(FR) DÉTERMINATION PRÉCOCE AMÉLIORÉE EN DÉCODAGE DE CANAL DE COMMANDE PARTAGÉ À HAUT DÉBIT
Abstract
(EN)
The disclosure provides for determining whether an encoded multi-part message in a channel is intended for a user equipment (UE). The UE may receive a codeword that can be a component of the encoded multi-part message. The UE may also de-mask the received codeword based on an assigned identifier assigned to the UE to provide a data sequence. The UE may also damask the received codeword based on re-encoding the data sequence to provide a detected identifier. The UE can also compare the detected identifier to the assigned identifier. The UE can be determined to be the intended recipient of the encoded multi-part message when the detected identifier is equal to the assigned identifier. The disclosure also provides for jointly determining a mask and a data sequence that approximates the encoded multi-part message.

L'invention permet de déterminer si un message en plusieurs parties codé dans un canal est destiné à un équipement utilisateur (UE). L'UE peut recevoir un mot de code qui peut être un élément du message en plusieurs parties codé. L'UE peut également dé-masquer le mot de code reçu, sur la base d'un identifiant attribué à l'UE, afin de produire une séquence de données. L'UE peut également dé-masquer le mot de code reçu sur la base d'un re-codage de la séquence de données afin de produire un identifiant détecté. L'UE peut également comparer l'identifiant détecté à l'identifiant attribué. L'UE peut déterminer qu'il est le destinataire prévu du message en plusieurs parties codé quand l'identifiant détecté est égal à l'identifiant attribué. L'invention permet également de déterminer conjointement un masque et une séquence de données qui est une approximation du message en plusieurs parties codé.
