Abstract
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.

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.
A base station configured for wireless communication on a reverse link in a machine-to-machine (M2M) wireless Wide Area Network (WAN), comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions being executable by the processor to:
- divide 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 the reverse link;
- broadcast 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;
- receive a request from a first M2M device to use the first frequency channel to transmit data on the reverse link;
- and
- transition the first channel status information from the idle status to indicate a busy status in response to the request.
An apparatus configured for wireless communication on a reverse link in a machine-to-machine (M2M) wireless Wide Area Network (WAN), comprising:
- means for 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 the reverse link;
- means for 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;
- means for receiving a request from a first M2M device to use the first frequency channel to transmit data on the reverse link;
- and
- means for transitioning the first channel status information from the idle status to indicate a busy status in response to the request.
A non-transitory computer readable medium for managing wireless communication on a reverse link in a machine-to-machine (M2M) wireless Wide Area Network (WAN), the non-transitory computer readable medium storing instructions executable by a processor to:
- divide 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 the reverse link;
- broadcast 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;
- receive a request from a first M2M device to use the first frequency channel to transmit data on the reverse link;
- and
- transition the first channel status information from the idle status to indicate a busy status in response to the request.
A method for wireless communication on a reverse link in a machine-to-machine (M2M) wireless Wide Area Network (WAN), comprising:
- receiving a first broadcast of a channel status message from a base station, the channel status message indicating a status of a first frequency channel and a status of a second frequency channel, wherein the first frequency channel has an idle status;
- transmitting a request to use the first frequency channel to transmit data on the reverse link;
- receiving a second broadcast of the channel status message from the base station, the channel status message indicating the status of the first frequency channel and the status of the second frequency channel, wherein the status of the first frequency channel has transitioned from the idle status to a busy status;
- and
- determining whether to use the first frequency channel to transmit a data packet based at least in part on the status of the first frequency channel.
