Techniques for aggregating data from WWAN and WLAN
First Claim
1. A method for aggregating data in wireless communications, the method comprising:
- communicating data packets, by a packet convergence entity, with a first radio access technology (RAT) link comprising a wireless wide area network (WWAN) link and a second RAT link comprising a wireless local area network (WLAN) link;
receiving, at the packet convergence entity from each of the first RAT link and the second RAT link, an indication to enable the packet convergence entity to identify which of the first and second RAT links each of the data packets is received by the packet convergence entity;
determining, at the packet convergence entity, which data packets are received from the first RAT link and the second RAT link based on the indications from the first RAT link and the second RAT link;
monitoring, at the packet convergence entity, a sequence number value of each of the data packets received on the first RAT link and the second RAT link;
determining, at the packet convergence entity, whether one or more data packets are missing based on the monitored sequence number values of the first RAT link and the second RAT link; and
sending, by the packet convergence entity, a status report in response to one or more events on one or both of the first RAT link and the second RAT link.

Abstract
Certain aspects of the present disclosure relate to techniques for aggregating data from a wireless wide area network (WWAN) and wireless local area network (WLAN). In some aspects, a packet convergence entity (e.g., PDCP layer entity) communicates with first and second radio access technology (RAT) links. The packet convergence entity may determine from which of the first and second RAT links a data packet is received and may monitor a sequence number value of each of the received data packets. The packet convergence entity may perform one or more actions based on a determination that one or more packets are missing based on the monitored sequence number values. The packet convergence entity may send a status report in response to one or more events on one or both of the first RAT link and the second RAT link.
