Publication number: 20230027103Abstract: 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.Type: ApplicationFiled: January 8, 2021Publication date: January 26, 2023Inventors: Konstantinos DIMOU, Piyush GUPTA, Kapil GULATI, Junyi LI, Jingyuan LIU, Alexander LEONIDOV, Sony AKKARAKARAN, Wooseok NAM, Yan ZHOU, Ozge KOYMEN, Tao LUO
