Patent number: 12219625Abstract: A method of connection establishment through a relay UE for a remote UE is proposed. The remote and relay UEs first perform discovery and establish a PC5 radio resource control (PC5-RRC) connection. Upon receiving a request from the remote UE, the relay UE and a serving gNB perform a relaying procedure for establishment of the remote UE's signalling radio bearer 1 (SRB1). The relay UE configures PC5 RLC channels for relaying of SRB1 towards the remote UE. The remote UE then enters an RRC_CONNECTED state. The remote UE and gNB establish security. The gNB configures additional data radio bearers (DRBs) for relaying. The relay UE configures PC5 RLC channels for relaying of the additional DRBs towards the remote UE. The DRBs can then be used for exchange of data between the remote UE and the gNB.Type: GrantFiled: September 14, 2021Date of Patent: February 4, 2025Assignee: MediaTek Inc.Inventors: Nathan Edward Tenny, Xuelong Wang, Guan-yu Lin
