Abstract
A user equipment (UE) can include processing circuitry configuring the UE for Dual Connectivity (DC) with a Master Node-B (MN) and a Secondary Node-B (SN). The processing circuitry is to decode connection reconfiguration information received from the MN. The connection reconfiguration information includes signaling radio bearer type 3 (SRB3) configuration information. The SRB3 configuration information originating from the SN and configuring a SRB3, where the SRB3 is for direct communication between the UE and the SN. At least one of a radio resource control (RRC) reconfiguration completion message or a measurement report message is encoded for transmission to the SN.
Claims24
An apparatus comprising:
- one or more processors, wherein the one or more processors are configured to cause a master node (MN) to:
- receive signaling radio bearer type 3 (SRB3) configuration information from a secondary node (SN), wherein the SRB3 is for direct communication between a user equipment device (UE) and the SN;
- provide first connection reconfiguration information to the UE, the connection reconfiguration information including the SRB3 configuration information;
- after providing the connection reconfiguration information to the UE, providing second connection reconfiguration information, wherein the second connection reconfiguration information includes signaling to release the SRB3.
A method for operating a user equipment (UE) comprising:
- by the UE:
- receiving signaling radio bearer type 3 (SRB3) configuration information from a master node (MN), the SRB3 for direct communication between the UE and a secondary node (SN);
- receiving connection reconfiguration information from the MN, wherein the connection reconfiguration information includes signaling to release the SRB3.
A non-transitory computer accessible memory medium storing program instructions executable by one or more processors of a secondary node (SN) to:
- provide signaling radio bearer type 3 (SRB3) configuration information to a user equipment (UE), the SRB3 for direct communication between the UE and the SN, wherein the UE is also in communication with a master node (MN), wherein said providing the SRB3 configuration information is provided in first connection reconfiguration information;
- provide second connection reconfiguration information to the UE, wherein the second connection reconfiguration information includes signaling to release the SRB3.
An apparatus comprising:
- one or more processors, wherein the one or more processors are configured to cause a user equipment (UE) to:
- receive signaling radio bearer type 3 (SRB3) configuration information from a secondary node (SN), the SRB3 for direct communication between the UE and the SN, wherein the UE is also in communication with a master node (MN), and wherein said receiving the SRB3 configuration information is provided in first connection reconfiguration information;
- receiving second connection reconfiguration information from the SN, wherein the second connection reconfiguration information includes signaling to release the SRB3.
