Abstract
A method for secondary node addition is provided. The method includes receiving, by a UE, a first RRC connection reconfiguration message from a master node, adding, by the UE, a secondary node in response to the first RRC connection reconfiguration message; and transmitting, by the UE, an RRC connection reconfiguration complete message to the secondary node via SRB3.

Claim
1. A User Equipment (UE) comprising:
one or more non-transitory computer-readable media having computer-executable instructions embodied thereon; and at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to: receive a first Radio Resource Control (RRC) connection reconfiguration message from a master node, the first RRC connection reconfiguration message including a Signaling Radio Bearer (SRB) 3 configuration; add a secondary node in response to the first RRC connection reconfiguration message; and transmit an RRC connection reconfiguration complete message to the secondary node via SRB3.
2. The UE according to claim 1, wherein the at least one processor is further configured to execute the computer-executable instructions to:
transmit a blind addition request to the master node via an RRC message.
3. The UE according to claim 1, wherein the at least one processor is further configured to execute the computer-executable instructions to:
receive a blind addition response from the master node via an RRC message.
4. The UE according to claim 1, wherein the at least one processor is further configured to execute the computer-executable instructions to:
report a cell selection result to the master node via an RRC message, the cell selection result indicating at least one candidate secondary node and comprising at least one of a cell identity (ID), a zone ID and an area ID.
5. The UE according to claim 4, wherein the at least one processor is further configured to execute the computer-executable instructions to:
receive a blind addition response from the master node via an RRC message, the blind addition response indicating at least one of a maximum number of reported cell IDs in the cell selection result, a maximum number of reported zone IDs in the cell selection result, and a maximum number of reported area IDs in the cell selection result.
6. The UE according to claim 1, wherein the at least one processor is further configured to execute the computer-executable instructions to:
transmit a UE capability message to the master node, the UE capability message indicating a maximum number of secondary nodes that the UE can support.
7. The UE according to claim 1, wherein the RRC connection reconfiguration complete message is transmitted in response to a second RRC connection reconfiguration message from the secondary node.
8. A base station comprising:
one or more non-transitory computer-readable media having computer-executable instructions embodied thereon; and at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to: transmit a secondary node addition request to a cell; receive a secondary node addition response from the cell, the secondary node addition response including an SRB3 configuration; add the cell as a secondary node in response to the secondary node addition response; and transmit an RRC connection reconfiguration message to a UE in response to the secondary node addition response message.
9. The base station according to claim 8, wherein the secondary node addition request comprises an ID of the UE.
10. The base station according to claim 8, wherein the at least one processor is further configured to execute the computer-executable instructions to:
receive a blind addition request from the UE via an RRC message.
11. The base station according to claim 8, wherein the at least one processor is further configured to execute the computer-executable instructions to:
transmit a blind addition response to the UE via an RRC message.
12. The base station according to claim 8, wherein the at least one processor is further configured to execute the computer-executable instructions to:
receive a cell selection result from the UE via an RRC message, the cell selection result indicating at least one candidate secondary node and comprising at least one of a cell ID, a zone ID and an area ID.
13. The base station according to claim 12, wherein the at least one processor is further configured to execute the computer-executable instructions to:
transmit a blind addition response to the UE via an RRC message, the blind addition response indicating at least one of a maximum number of reported cell IDs in the cell selection result, a maximum number of reported zone IDs in the cell selection result, and a maximum number of reported area IDs in the cell selection result.
14. The base station according to claim 8, wherein the at least one processor is further configured to execute the computer-executable instructions to:
receive a UE capability message from the UE, the UE capability message indicating a maximum number of secondary nodes that the UE can support.
15. A method comprising:
receiving, by a UE, a first RRC connection reconfiguration message from a master node, the first RRC connection reconfiguration message including an SRB3 configuration; adding, by the UE, a secondary node in response to the first RRC connection reconfiguration message; and transmitting, by the UE, an RRC connection reconfiguration complete message to the secondary node via SRB3.
16. The method according to claim 15, further comprising:
transmitting, by the UE, a blind addition request to the master node via an RRC message.
17. The method according to claim 15, further comprising:
receiving, by the UE, a blind addition response from the master node via an RRC message.
18. The method according to claim 15, further comprising:
reporting, by the UE, a cell selection result to the master node via an RRC message, the cell selection result indicating at least one candidate secondary node and comprising at least one of a cell ID, a zone ID and an area ID.
19. The method according to claim 18, further comprising:
receiving, by the UE, a blind addition response from the master node via an RRC message, the blind addition response indicating at least one of a maximum number of reported cell IDs in the cell selection result, a maximum number of reported zone IDs in the cell selection result, and a maximum number of reported area IDs in the cell selection result.
20. The method according to claim 15, further comprising:
transmitting, by the UE, a UE capability message to the master node, the UE capability message indicating a maximum number of secondary nodes that the UE can support.
21. The method according to claim 15, wherein the RRC connection reconfiguration complete message is transmitted in response to a second RRC connection reconfiguration message from the secondary node.
