Embodiment Construction

[0023] The techniques described herein may be used in a variety of communication networks, including wireless and wired communication networks. The terms "network" and "system" are often used interchangeably. The wireless network may be a Wireless Wide Area Network (WWAN), a Wireless Metropolitan Area Network (WMAN), a Wireless Local Area Network (WLAN), or the like. The wired network may be a Wide Area Network, a Metropolitan Area Network (MAN), a Local Area Network (LAN), a cable television network, a computer network, and the like. For clarity, certain aspects of the techniques are described below with respect to wireless networks.

[0024] The techniques described herein may also be used to send various types of control information. For example, the technique may be used to send congestion information indicative of traffic congestion observed by a node. The technique can also be used to send other control information, such as routing information, node capability informa...

Abstract

Techniques for sending control information in the header of multiple packets are described. The techniques may allow more control information to be sent using a small number of overhead bits per packet. In one design, a first node (e.g., a network entity) may determine control information to send to a second node (e.g., a UE or another network entity). The first node may send the control information in the header of multiple packets toward the second node. In one design, the control information may include congestion information indicative of traffic congestion at the first node. The congestion information may be sent using Explicit Congestion Notification (ECN) bits in the header of IP packets. The first node may send the control information with or without coding and for all packets or a specific data flow. The first node may also send a synchronization sequence prior to the control information.

Description

[0001] This application claims priority to U.S. Provisional Application Serial No. 61 / 222,590, filed July 2, 2009, entitled "CODING CONGESTION INFORMATION ACROSS MULITPLE PACKETS," which is assigned to the assignee of this application, It is incorporated into this application by reference. technical field [0002] In general, the present disclosure relates to communications, and in particular, the present disclosure relates to techniques for sending control information in a communications network. Background technique [0003] Communication networks are widely deployed to provide various communication services such as voice, video, data, messaging, broadcast, and so on. A communication network may include a number of network entities capable of supporting communication for a number of user equipments (UEs). A communication network may receive packets from a given UE and may forward these packets to a server or to a remote UE. Packets may also be called data packets, datagr...
