Embodiment Construction

[0027] The detailed description described below in connection with the accompanying drawings is intended as a description of various configurations, and is not intended to represent the only configurations in which the concepts described herein may be implemented. The detailed description includes specific details to provide a thorough understanding of various concepts. It will be apparent, however, to one skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts.

[0028] The techniques described herein may be used for various wireless communication networks such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA, and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), CDMA2000, and so on. UTRA includes Wi...

Abstract

Techniques for aggregating heterogeneous carriers in a wireless communication system are disclosed. A mobile device may receive a configuration for aggregating a plurality of component carriers including one or more cellular carriers and a wireless local area network (WLAN) carrier. The one or more cellular carriers may include LTE carriers, and aggregation may be performed at a sub-IP protocol layer of operation. In one aspect, protocol entities may be modified to perform quality of service determinations, carrier selection, traffic mapping, or the like, in view of the different capabilities and characteristics of the heterogeneous carriers in the carrier aggregation configuration.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to Provisional Application No. 61 / 612,127, filed March 16, 2012, entitled "SYSTEM AND METHOD FOR CELLULAR-WLAN CARRIER AGGREGATION," which is assigned to the assignee of this application person, the entire contents of which are expressly incorporated herein by reference. technical field [0003] In general, certain aspects of the present invention relate to wireless communication systems, and in particular, to the aggregation of heterogeneous carriers below the Internet Protocol (IP) layer of operation. Background technique [0004] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and so on. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing available network resources. Examples of these multiple access networks include Code ...
