Layer 2 relay supporting coverage and resource-constrained devices in wireless networks |
| abstract |
A wearable device (smart watch) (UE) that communicates with the eNB through the relay function or relay service (RD) of the mobile terminal (smartphone). Two modes of operation: 1) RD acts as a donor eNB (DeNB) through the Un interface to the UE, and acts as a regular UE towards the eNB through the Uu interface; 2) RD uses the ProSe relay function and establishes a PC5-interface towards the UE, and using the Uu interface to the eNB. Issues: 1) Donor eNB functions required in RD and MME need to know the type of eNB functions of RD and eNB, 2) ProSe works on IP layer where RD is the termination point and UE is not the termination point. Hence all data and signaling to the UE can be read by the RD. Solution: A secure layer 2 radio level relay connection is established through RD. The RD acts as the termination point of the connection to the eNB and the PC5 connection is established between the UE and the RD. The eNB assigns a separate CRNTI‑R to the UE, which is then used for the relay connection, so separate data streams are sent on the Uu interface between the RD and the eNB, one to the RD itself and one to the RD Go to UE. |
