Abstract
Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for delivering a radio resource control layer (RRC) message between a donor next generation NodeB (dgNB) centralized unit (CU) and a user equipment (UE) by a relay RRC message between a dgNB distributed unit (DU) and the dgNB CU through an adaption layer operated on the dgNB DU. Other embodiments may be described and claimed.
Claims25
One or more non-transitory, computer-readable media having instructions that, when executed, cause a donor next generation NodeB (dgNB) distributed unit (DU) to:
- generate, by an adaption layer, a relay radio resource control (RRC) message to include an RRC connection request message received from a relay node (RN) distributed unit (DU), an RRC connection setup message received from a dgNB centralized unit (CU), or an RRC connection setup complete message received from the RN-DU;
- and
- transmit or cause to be transmitted the relay RRC message to the DgNB CU or the RN-DU.
An apparatus to be used in a donor next generation NodeB (dgNB) distributed unit (DU), the apparatus comprising:
- processing circuitry to set up a connection with a donor next generation NodeB (dgNB) centralized unit (CU), and set up a connection with a user equipment (UE) through a relay node distributed unit (RN-DU), wherein the UE is among one or more UEs attached to the RN-DU;
- and
- network controller circuitry, coupled with the processing circuitry, to deliver a radio resource control layer (RRC) message between the dgNB CU and the UE by a relay RRC message between the dgNB DU and the dgNB CU through an adaption layer operated on the dgNB DU.
One or more non-transitory, computer-readable media having instructions that, when executed, cause a donor next generation NodeB (dgNB) centralized unit (CU) to:
- receive or cause to receive an uplink relay radio resource control (RRC) message from a dgNB distributed unit (DU), wherein the uplink relay RRC message includes an RRC connection request message received from a relay node (RN) distributed unit (DU) through the dgNB DU, an RRC connection setup complete message received from the RN-DU, or a RRC message from a user equipment (UE) to the dgNB CU, wherein the uplink relay RRC message is generated by an adaption layer operated on the dgNB DU, and the UE is among one or more UEs attached to the RN-DU;
- and
- transmit or cause to be transmitted a downlink relay RRC message to the dgNB DU, wherein the downlink relay RRC message includes an RRC connection setup message, or a RRC message from the dgNB CU to the UE.
