Title
(EN) EARLY DETECTION OF FORWARDING FOR MULTI-HOP ULTRA-RELIABLE LOW LATENCY COMMUNICATIONS
(FR) DÉTECTION PRÉCOCE DE TRANSFERT POUR DES COMMUNICATIONS À FAIBLE LATENCE ULTRA-FIABLES À PLUSIEURS BONDS
Abstract
(EN)
Methods, systems, and devices for wireless communications are described. In some communications systems, interference may impede signaling between a base station and a target user equipment (UE) such that a base station may identify a donor UE to relay communications to the target UE. The donor UE may receive a coded data packet from the base station, and may identify a radio network temporary identifier (RNTI) scrambling code for the packets addressed to the target UE. In cases where the donor UE identifies that the packet has an RNTI scrambling code associated with the target UE, the donor UE may forward the coded data packet to the target UE base on the RNTI scrambling code. Such early detection of data packets addressed to the target UE may allow for the UE to forward a data packet without fully decoding the packet.

Sont décrits des procédés, des systèmes et des dispositifs de communication sans fil. Dans certains systèmes de communication, un brouillage peut empêcher une signalisation entre une station de base et un équipement utilisateur (UE) cible de telle sorte qu'une station de base peut identifier un UE donneur afin de relayer des communications à l'UE cible. L'UE donneur peut recevoir un paquet de données codé en provenance de la station de base, et peut identifier un code d'embrouillage d'identifiant temporaire de réseau radio (RNTI) destiné aux paquets adressés à l'UE cible. Dans les cas où l'UE donneur identifie que le paquet a un code d'embrouillage RNTI associé à l'UE cible, l'UE donneur peut transférer le paquet de données codé à l'UE cible sur la base du code d'embrouillage RNTI. Une telle détection précoce de paquets de données adressés à l'UE cible peut permettre à l'UE de transférer un paquet de données sans décoder complètement le paquet.
