Abstract

Technology for a user equipment (UE) to perform long-term evolution (LTE) and Wireless local area network (WLAN) aggregation (LWA) connection procedures within a wireless communication network is disclosed. The UE can determine to suspend communication on a wireless local area network (WLAN) of one or more protocol data units (PDUs) for a LWA session without terminating the LWA session. The UE can process, for transmission to an eNodeB, a request to suspend communication of the one or more PDUs on the WLAN to enable the eNodeB to schedule the one or more PDUs for transmission to the UE through a cellular interface without terminating the LWA session.

First claim

What is claimed is:

1. An apparatus of a user equipment (UE), the UE configured to perform long-term evolution (LTE) and wireless local area network (WLAN) aggregation (LWA), the apparatus comprising:
a baseband processor; and
a memory for storing instructions;
the baseband processor to:
determine, during operation of the UE in an LWA session, to suspend communication on a WLAN of the LWA session; and
process, for transmission to an eNodeB, a request to suspend communication on the WLAN without terminating an LTE portion of the LWA session;
send the request to suspend communication on the WLAN to the eNodeB using the LTE portion of the LWA session;
process, for transmission to the eNB, a request to resume the communication on the WLAN belonging to an LWA split bearer; and
send the request to resume the communication on the WLAN belonging to an LWA split bearer to the eNB.

2. The apparatus of claim 1 , wherein the baseband processor is to:
process, for transmission to the eNodeB, a request to resume the communication on the WLAN for the LWA session; and
send the request to resume communication on the WLAN for the LWA session.

3. The apparatus of claim 1 , wherein the baseband processor is to:
process, for transmission to the eNodeB, a request to suspend communication on the WLAN belonging to an LWA split bearer; and
send the request to suspend communication on the WLAN belonging to an LWA split bearer to the eNodeB.

4. The apparatus of claim 1 , wherein the baseband processor is to:
process a radio resource control (RRC) signaling message comprising a request to suspend the communication on the WLAN for the LWA session; and
send the RRC signaling message to the eNodeB.

5. The apparatus of claim 4 , wherein the baseband processor is to:
process a radio resource control (RRC) signaling message comprising a request to resume the communication on the WLAN for the LWA session; and
send the RRC signaling message to the eNodeB.

6. The apparatus of claim 4 , wherein the RRC signaling message comprises a WLAN Connection Status Report message.

7. The apparatus of claim 1 , wherein the request to suspend communication on a WLAN for an LWA session comprises a WLAN Connection Status Report message.

8. The apparatus of claim 1 , the apparatus to suspend communication on the WLAN.

9. A method comprising:
determining by a processor of a user equipment (UE), during operation of the UE in a long term evolution (LTE) and wireless local area network (WLAN) aggregation (LWA) session, to suspend communication on a WLAN of the LWA session; and
processing, for transmission to an eNodeB, a request to suspend communication on the WLAN without terminating an LTE part of the LWA session;
sending the request to suspend communication on the WLAN to the eNodeB;
processing, for transmission to the eNodeB, a request to resume the communication on the WLAN belonging to an LWA split bearer; and
sending the request to resume the communication on the WLAN belonging to an LWA split bearer to the eNodeB.

10. The method of claim 9 , further comprising:
processing, for transmission to the eNodeB, a request to resume the communication on the WLAN for the LWA session; and
sending the request to resume communication on the WLAN for the LWA session.

11. The method of claim 9 , further comprising:
processing, for transmission to the eNodeB, a request to suspend communication on the WLAN belonging to an LWA split bearer; and
sending the request to suspend communication on the WLAN belonging to an LWA split bearer to the eNodeB.

12. The method of claim 9 , further comprising:
processing a radio resource control (RRC) signaling message comprising a request to suspend the communication on the WLAN for the LWA session; and
sending the RRC signaling message to the eNodeB.

13. The method of claim 12 , further comprising:
processing a radio resource control (RRC) signaling message comprising a request to resume the communication on the WLAN for the LWA session; and
sending the RRC signaling message to the eNodeB.

14. The method of claim 12 , wherein the RRC signaling message comprises a WLAN Connection Status Report message.

15. The method of claim 9 , wherein the request to suspend communication on a WLAN for an LWA session comprises a WLAN Connection Status Report message.

16. The method of claim 9 , further comprising suspending communication on the WLAN.
