Title: LWIP (LTE/WLAN RADIO LEVEL INTEGRATION USING IPSEC TUNNEL) PACKET ACKNOWLEDGMENT USING GRE (GENERIC ROUTING ENCAPSULATION) HEADER
Abstract:
Techniques discussed herein can facilitate acknowledgment and/or re-ordering of LWIPEP (LWIP (LTE (Long Term Evolution)/WLAN (Wireless Local Area Network) Radio Level Integration Using IPSec (Internet Protocol Security) Tunnel) Encapsulation Protocol) packets. In various aspects employing a LWIP acknowledgment mode, LWIPEP packets can comprise an enhanced GRE (Generic Routing Encapsulation) header comprising a SN (Sequence Number) of the payload of that LWIPEP packet, which can facilitate acknowledgment of LWIPEP packets and re-ordering of LWIPEP packets (e.g., communicated over a WLAN link, an LTE link, or both) based on the SN(s) indicated in the enhanced GRE header(s).
