Abstract: Recovering bearers after a service interruption of a relay node includes receiving, at a relay gateway, an instruction to modify bearers from a mobility management entity (MME), the instruction identifying one or more bearers that were in use by the relay node prior to the service interruption, identifying, at the relay gateway, at least one additional bearer in use prior to the service interruption not identified in the instruction received from the MME, and instructing the MME to create the at least one additional bearer. The at least one additional bearer can include a non-GBR bearer, such as a bearer with QCI of 1 used for VoLTE.

Abstract: A method and system for controlling configuration of a relay, where the relay has a coverage footprint and provides service on a first air interface having a frequency bandwidth, and where the relay is served by a donor access node over a second air interface on which the donor access node provides service. Per the disclosure, an entity detects that load on the second air interface on which the donor access node provides service is threshold high, and in response to at least that detecting, the relay is made to reduce the coverage footprint of the relay and/or to reduce the frequency bandwidth of the first air interface on which the relay provides service.

Abstract: In a wireless communication relay, a network transceiver wirelessly detects wireless access points. The network transceiver beamforms wireless test signals and wirelessly transmits the beamformed wireless test signals to the wireless access points. A user transceiver in the relay wirelessly detects cross-relay interference levels when the network transceiver wirelessly transmits the beamformed wireless test signals to the wireless access points. The user transceiver transfers the cross-relay interference levels for the wireless access points to the network transceiver. The network transceiver selects one of the wireless access points based on the cross-relay interference levels for the wireless access points. The network transceiver wirelessly exchanges user data with the selected one of the wireless access points and exchanges the user data with the user transceiver.

Abstract: Relaying data comprises assigning a first network address to a relay wireless device attached to an access node, wherein the relay wireless device is communicatively coupled to one or more wireless access points (WAPs); and instructing the relay wireless device to correspondingly assign one or more additional network addresses to the one or more WAPs, wherein the relay wireless device is configured to relay data between the access node and one or more end-user wireless devices attached to any of the one or more WAPs. Port NAT and DHCP are leveraged at the relay UE according to embodiments described herein.

Abstract: A wireless relay mitigates cross-relay interference when serving wireless user devices. A network transceiver detects wireless access points and determines signal strengths for the wireless access points. The network transceiver transmits test signals to the wireless access points and directs a user transceiver to detect interference levels during the test. The network transceiver uses the interference level reported by user transceiver to calculate the interference level it would receive from the transmitter of user transceiver with a certain algorithm. The network transceiver selects wireless access points based on their signal strength and calculated cross-relay interference levels. The network transceiver exchanges user data with the selected wireless access points. The user transceiver exchanges the user data with the wireless user devices.

Abstract: A wireless communication relay tests data throughputs over a Fifth Generation New Radio (5GNR) network XCVR and a wireline network XCVR. The testing over the wireline network XCVR comprises a test of the data throughputs through a Local Break-Out (LBO) router or an N3 Interworking Function (N3IWF). The relay selects one of the 5GNR network XCVR and the wireline network XCVR based on the data throughput testing and indicates the selected network XCVR to a user XCVR. The user XCVR exchanges user data with the wireless UE and exchanges the user data with the selected one of the 5GNR network XCVR and the wireline network XCVR. The selected one of the 5GNR network XCVR and the wireline network XCVR exchanges the user data with one or more data communication networks.

Abstract: Selecting a donor access node for a relay node based on a number of component carriers includes identifying one or more potential donor access nodes deploying one or more carriers, measuring a reference signal strength for each of the one or more potential donor access nodes, determining which of the one or more potential donor access nodes deploys a highest number of component carriers, and sending a request to attach to the potential donor access node deploying the highest number of component carriers and having a reference signal strength that meets a reference signal criteria.

Relay circuitry tests data throughputs over a Fifth Generation New Radio (5GNR) network Transceiver (XCVR), Long Term Evolution (LTE) network XCVR, and wireline network XCVR.

The user XCVRs wirelessly exchange user data with the wireless UEs and exchange the user data with the selected network XCVRs. The selected network XCVRs exchange the user data with one or more data communication networks.

Primary and secondary carriers can be identified and communicated with potential donor access nodes.

Abstract: Systems, methods, and processing nodes for communicating using at least two different radio access technologies (RATs) include determining whether or not an access node is capable of communicating using the at least two RATs (e.g. using 4G LTE and 5G NR, also known as 5G EN-DC), and instructing the access node to broadcast an indicator, wherein receiving the indicator, a wireless device can attach to both first and second RATs. The wireless device is further instructed to prioritize which combination of RATs to attach to based on a signal level transmitting using each RAT.
