Embodiment Construction

[0032] Various aspects of the present disclosure are described below. Obviously, the teachings herein can be embodied in various forms, and any specific structure, function, or both disclosed herein are merely representative. Based on the teachings described herein, those skilled in the art should understand that the solutions disclosed herein can be implemented independently of any other solutions, and two or more of these solutions can be combined in various ways. For example, any of the solutions proposed here can be used to implement the device or method. In addition, other structures, functions, or structures and functions in addition to one or more of the solutions proposed herein can be used to implement this device or implement this method. For example, in some aspects, the sending node determines whether to issue a sending request based on the node's received scheduled receptions about neighboring nodes. In addition, in some aspects, the receiving node determines whether ...

Abstract

A scheduled transmission may be divided up into several segments so that a transmitting node may receive and transmit control messages between segments. In some implementations a monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may otherwise have been transmitted during the scheduled transmission period. In some implementations a wireless media access control supports asynchronous communication and overlapping transmissions. Here, a wireless node may determine whether to request or schedule a transmission based on control messages it receives from neighboring nodes. In some implementations data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

Description

[0001] Claim priority under 35 U.S.C. §119 [0002] This application claims rights and priority to the jointly owned U.S. Provisional Application Serial No. 60 / 836,179. The provisional application was filed on August 7, 2006, and was assigned the Agent Record No. 061675P1, the disclosure of which is incorporated by reference Here. Technical field [0003] This application relates generally to wireless communications, and particularly but not exclusively to media access control for asynchronous wireless systems. Background technique [0004] Various network topologies can be used to establish wireless communication. For example, depending on the specific wireless communication capabilities required by a given application, a wide area network, a local area network, or some other type of network can be deployed. [0005] Wireless WAN is a typical planned deployment in the licensed frequency band. Such networks can be used to optimize spectrum efficiency and service quality to support...
