Multiple access scheme for narrowband channels

摘要

Methods, systems, and devices for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). An operating frequency band of the M2M wireless WAN is divided into at least a first frequency channel and a second frequency channel. The first and second frequency channels being used for communications on a reverse link. First channel status information and second channel status information are broadcasted to one or more M2M devices. The first channel status information indicating a status of the first frequency channel. The second channel status information indicating a status of the second frequency channel.

1. A method for wireless communication in a machine-to-machine (M2M) wireless Wide Area Network (WAN), comprising:
dividing an operating frequency band of the M2M wireless WAN into at least a first frequency channel and a second frequency channel, the first and second frequency channels being used for communications on a reverse link; broadcasting first channel status information and second channel status information to one or more M2M devices, the first channel status information indicating an idle status of the first frequency channel, the second channel status information indicating a status of the second frequency channel; receiving a request from a first M2M device to use the first frequency channel to transmit data on the reverse link; and transitioning the first channel status information from the idle status to indicate a busy status in response to the request.
