Abstract: This disclosure relates to techniques for performing radio resource control procedures for remote wireless devices in a wireless communication system. A relay wireless device may receive respective radio resource control, RRC, connection requests from a plurality of remote wireless devices and may relay RRC messages, including a respective RRC setup complete message between a cellular base station and each of the plurality of remote wireless devices to establish an RRC connection with the cellular base station. Each RRC setup complete message is relayed between a respective remote wireless device of the plurality of remote wireless devices and the cellular base station on a Uu link between the relay wireless device and the cellular base station and is transmitted together on the Uu link with a respective remote wireless device identifier in order to distinguish different remote wireless devices' respective RRC setup complete messages.

Abstract: This disclosure relates to techniques for performing radio resource control procedures for remote wireless devices in a wireless communication system. A relay wireless device relays radio resource control, RRC, messages between a cellular base station and a remote wireless device to establish an RRC connection with the cellular base station. The relay device transmits an indication to the remote wireless device of the radio link failure in the Uu link to cause the remote wireless device to perform RRC re-establishment once a radio link failure in a Uu link is determined.
