Title
(EN) CHANNEL QUALITY REPORTING USING RANDOM ACCESS MESSAGES
(FR) RAPPORT DE QUALITÉ DE CANAL À L'AIDE DE MESSAGES D'ACCÈS ALÉATOIRE
Abstract
(EN)
Methods, systems, and devices for wireless communications are described that support channel quality reporting using random access messages. A user equipment (UE) may receive a random access message from a base station and respond with an indication of channel quality information for a communication link between the base station and the UE. The indication may be generated by a single protocol layer of a control plane protocol stack (e.g., a radio resource control (RRC) or media access control (MAC) layer). The channel quality information may be included in the RRC message or in a header of the MAC layer from the UE. The UE may transmit, to the base station, an indication of identified channel quality information. Upon receiving the response message from the UE, the base station may determine communication parameter(s) (e.g., coding rate, modulation order, number of repetitions of a channel) for future communications with the UE.

L'invention concerne des procédés, des systèmes et des dispositifs de communication sans fil qui prennent en charge un rapport de qualité de canal à l'aide de messages d'accès aléatoire. Un équipement utilisateur (UE) peut recevoir un message d'accès aléatoire en provenance d'une station de base et répondre par une indication d'informations de qualité de canal pour une liaison de communication entre la station de base et l'UE. L'indication peut être générée par une couche de protocole unique d'une pile de protocoles de plan de commande (par exemple, une couche de commande de ressources radio (RRC) ou de commande d'accès au support (MAC)). Les informations de qualité de canal peuvent être incluses dans le message RRC ou dans un en-tête de la couche MAC provenant de l'UE. L'UE peut transmettre à la station de base une indication d'informations de qualité de canal identifiées. Lors de la réception du message de réponse en provenance de l'UE, la station de base peut déterminer un ou plusieurs paramètres de communication (par exemple, rendement de codage, ordre de modulation, nombre de répétitions d'un canal) pour de futures communications avec l'UE.
