    Abstract: Methods, systems, and devices for wireless communications are described. a user equipment (UE) may receive, for a base station, a configuration message indicating a set of random access resources associated with monitoring by a relay node. The UE may transmit a random access message using the random access resources to the relay node and a timing advance associated with uplink data transmissions by the UE. The UE may then communicate with the base station via the relay node based on the random access message. In some examples, a UE may monitor for a relay reference signal from a relay node. The UE may determine a signal strength and a timing of the relay reference signal. The UE may determine whether an RSRP satisfies a threshold receive power, and may determine whether the timing of the relay reference signal is less than a timing threshold. The UE may transmit a downlink relay request to the base station to initiate relay communications.

    Abstract: A wireless relay serves a first User Equipment (UE). A first eNodeB in the relay wirelessly exchanges UE signaling data and UE user data with the first UE. The first eNodeB processes the UE signaling data to generate S1-MME signaling data and exchanges the S1-MME signaling data with a second UE in the relay. The first eNodeB processes the UE user data to generate S1-U user data and exchanges the S1-U user data with a Local Serving Gateway (L-SGW) in the relay. The L-SGW terminates the S1-U user data to generate non-General Packet Radio Service Transfer Protocol (non-GTP) user data. The L-SGW exchanges the non-GTP user data with the second UE in the relay. The second UE compresses/decompresses the non-GTP user data and the S1-MME signaling data. The second UE wirelessly exchanges the compressed non-GTP user data the compressed S1-MME signaling data with a second eNodeB.

    Abstract: A method, a base station, and a system of configuring relay link resources are provided according to the embodiments of the present invention. The method of configuring relay link resources includes: receiving an orthogonal frequency division multiplexing OFDM symbol number reported by a relay node RN, in which the OFDM symbol is used by a physical downlink control channel PDCCH of a multimedia multicast broadcast single frequency network MBSFN subframe where a relay link of the RN is located; and configuring relay link resources according to the OFDM symbol number, an offset, and a length of a PDCCH in an eNB subframe, in which the offset is an offset of an RN frame relative to the time when the RN frame is initially synchronized with an eNB frame, and is smaller than a sum of a length of the PDCCH of the MBSFN subframe where the relay link of the RN is located and a first idle time. The method increases relay link resources and reduces resource waste.
