Abstract

A method performed by a middle node in a communication system includes: receiving a request message for capability information from a controller; transmitting capability information of the middle node as a response to the request message; and receiving configuration information for an extended antenna carrier (eAxC)_identifier (ID) group supporting Section Extension 10 based on the capability information of the middle node from the controller.

First claim

What is claimed is:

1 . A method performed by a middle node in a communication system, the method comprising:
identifying a section type 3 control plane message indicating an uplink packet; determining user plane symbol reference timing based on the section type 3 control plane message; determining combining timing based on the determined user plane symbol reference timing; and paging and combining a stored uplink packet based on the determined combining timing.

2 . The method of claim 1 , wherein the determining of user plane symbol reference timing based on the section type 3 control plane message comprises:
identifying at least one of timing parameter, symbolid, timeoffset, cplength, framestructure (subcarrier spacing (SCS)), and numsymbol information included in the control plane message; and determining user plane symbol reference timing based on the identified information and a subframe boundary or slot boundary.

3 . The method of claim 1 , wherein the paging and combining of a stored uplink packet based on the determined combining timing comprises:
paging data corresponding to the determined combining timing based on symbolid, extended antenna carrier (eAxC)_ID, and transport flow; and, when there are pieces of data with the same symbolid, eAxC_ID, and transport flow and different user plane symbol reference timings, paging data corresponding to the determined combining timing based on filterIndex, sectionId, subframeId, or slotId included in the uplink packet, wherein the transport flow is determined by a combination of a destination and source of a medium access control (MAC) address or an Internet protocol (IP) address.

4 . The method of claim 3 , wherein the paging of data corresponding to the determined combining timing based on the filterIndex included in the uplink packet comprises:
identifying, when a value of the filterIndex is 1 to 7, that a corresponding message is a physical random access channel (PRACH) message and paging data; and identifying, when a value of the filterIndex is 8, that a corresponding message is a narrowband physical uplink shared channel (NPUSCH) message and paging data.

5 . The method of claim 3 , wherein the paging of data corresponding to the determined combining timing based on the sectionId included in the uplink packet comprises:
referring to sectionId in a control plane message indicating the uplink packet, identifying a user plane message including the sectionId and paging data.

6 . A middle node in a communication system, the middle node comprising:
a transceiver; a memory; and at least one processor electrically connected to the transceiver and the memory, wherein the at least one processor is configured to: identify a section type 3 control plane message indicating an uplink packet; determine user plane symbol reference timing based on the section type 3 control plane message; determine combining timing based on the determined user plane symbol reference timing; and page and combine a stored uplink packet based on the determined combining timing.

7 . The middle node of claim 6 , wherein the at least one processor is configured to:
identify at least one of timing parameter, symbolid, timeoffset, cplength, framestructure (subcarrier spacing (SCS)), and numsymbol information included in the control plane message; and determine user plane symbol reference timing based on the identified information and a subframe boundary or slot boundary.

8 . The middle node of claim 6 , wherein the at least one processor is configured to:
page data corresponding to the determined combining timing based on symbolid, extended antenna carrier (eAxC)_ID, and transport flow; and, when there are pieces of data with the same symbolid, eAxC_ID, and transport flow and different user plane symbol reference timings, page data corresponding to the determined combining timing based on filterIndex, sectionId, subframeId, or slotId included in the uplink packet, wherein the transport flow is determined by a combination of a destination and source of a medium access control (MAC) address or an Internet protocol (IP) address.

9 . The middle node of claim 8 , wherein the at least one processor is configured to:
identify, when a value of the filterIndex is 1 to 7, that a corresponding message is a physical random access channel (PRACH) message and page data; and identify, when a value of the filterIndex is 8, that a corresponding message is a narrowband physical uplink shared channel (NPUSCH) message and page data.

10 . The middle node of claim 8 , wherein the at least one processor is configured to:
referring to sectionId in a control plane message indicating the uplink packet, identify a user plane message including the sectionId and page data.
