Abstract
A multi-mode capable LTE-5G new radio (NR) user equipment (UE) for receiving LTE radio resource connection (RRC) messages is described. The UE receives an LTE RRC message from an evolved node B (eNB). The UE also determines which data radio bearer (DRB) to offload to a particular 5G NR system. The UE establishes an RRC with the 5G NR system. The UE steers a particular DRB or DRBs to the 5G NR system. The UE acknowledges receiving the LTE RRC message using LTE or NR connections. The UE updates an LTE system with a status of connections to the 5G NR system.
Claims5
A user equipment (UE), comprising:
- a processor;
- and
- a memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
- receive an RRCConnectionReconfiguration message from an E-UTRA evolved node B (eNB), wherein the RRCConnectionReconfiguration message is received over an LTE air interface, the RRCConnectionReconfiguration message comprises information elements (IEs) indicating a new radio (NR) configuration information, and the NR configuration information indicates an identity of an NR-Signaling Radio Bearer (SRB) for NR RRC message;
- perform, according to the NR configuration information, addition of the NR-SRB for NR RRC message over an NR air interface which is different from the LTE air interface;
- send information indicating a failure type as NR Radio Link failure.
A method performed by a user equipment (UE), comprising:
- receiving an RRCConnectionReconfiguration message from an E-UTRA evolved node B (eNB), wherein the RRCConnectionReconfiguration message is received over an LTE air interface, the RRCConnectionReconfiguration message comprises information elements (IEs) indicating a new radio (NR) configuration information, and the NR configuration information indicates an identity of an NR-Signaling Radio Bearer (SRB) for NR RRC message;
- performing, according to the NR configuration information, addition of the NR-SRB for NR RRC message over an NR air interface which is different from the LTE air interface;
- and
- sending information indicating a failure type as NR Radio Link failure.
An E-UTRA evolved node B (eNB), comprising:
- a processor;
- and
- a memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
- send an RRCConnectionReconfiguration message to a user equipment (UE), wherein the RRCConnectionReconfiguration message is received over an LTE air interface of the UE, and the RRCConnectionReconfiguration message comprises information elements (IEs) indicating a new radio (NR) configuration information which indicates an identity of an NR-Signaling Radio Bearer (SRB) for NR RRC message and which is used to cause the UE to perform addition of the NR-SRB for NR RRC message over an NR air interface of the UE which is different from the LTE air interface;
- and
- receive, from the UE, information indicating a failure type as NR Radio Link failure.
