Abstract
Embodiments are directed to interference-aware link-rate adaptation for wireless communication. An embodiment of a storage medium includes instructions to operations including receiving data regarding wireless signals received by an access point, the access point to provide Wi-Fi communication, the wireless signals being communicated in an unlicensed radio spectrum; performing spectral analysis of the received wireless signals to identify a channel of an LTE (Long-Term Evolution) signal; and upon determining that energy level of the LTE signal is below an energy detection (ED) level and that the channel is a primary Wi-Fi channel for the access point, adapting a link rate for the access point based on channel state information for the channel.
Claims15
One or more non-transitory computer-readable storage mediums having stored thereon executable computer program instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- receiving data regarding wireless signals received by an access point, the access point to provide Wi-Fi communication, the wireless signals being communicated in an unlicensed radio spectrum;
- performing spectral analysis of the received wireless signals to identify a channel of an LTE (Long-Term Evolution) signal;
- and
- upon determining that energy level of the LTE signal is below an energy detection (ED) level and that the channel is a primary Wi-Fi channel for the access point, adapting a link rate for the access point based at least in part on channel state information for the channel;
- upon determining that energy level of the LTE signal is above the ED level and that the channel is a secondary Wi-Fi channel for the access point, adapting spectrum allocation for the access point to avoid the channel;
- maintaining data for one or more detection metrics in a set of variables;
- and
- applying one or more detection conditions based on the set of detection metrics to detect clients of the access point that are affected by interference caused by the LTE signal.
An access point comprising:
- a processor;
- a transmitter and receiver for Wi-Fi communication;
- and
- firmware including rate control and interference mitigation code to provide interference-aware link-rate adaptation, wherein the access point is to:
- receive data regarding wireless signals received by access point, the access point to provide Wi-Fi communication, the wireless signals being communicated in an unlicensed radio spectrum,
- perform spectral analysis of the received wireless signals to identify a channel of an LTE (Long-Term Evolution) signal, and
- upon determining that energy level of the LTE signal is below an energy detection (ED) level and that the channel is a primary Wi-Fi channel for the access point, adapting a link rate for the access point based at least in part on channel state information for the channel;
- upon determining that energy level of the LTE signal is above the ED level and that the channel is a secondary Wi-Fi channel for the access point, adapt spectrum allocation for the access point to avoid the channel;
- and
- a memory, the access point to maintain data for one or more detection metrics in a set of variables in the memory, wherein the access point is to apply one or more detection conditions based on the set of detection metrics to detect clients of the access point that are affected by interference caused by the LTE signal.
A method for interference aware rate adaptation comprising:
- receiving data regarding wireless signals received by Wi-Fi access point, wherein the wireless signals are communicated in an unlicensed radio spectrum;
- performing spectral analysis of the received wireless signals to identify a channel of an LTE (Long-Term Evolution) signal;
- determining whether an energy level of the LTE signal is above or below an energy detection (ED) level;
- upon determining that energy level of the LTE signal is below the ED level and that the channel is a primary Wi-Fi channel for the access point, adapting a link rate for the access point based at least in part on channel state information for the channel;
- and
- upon determining that energy level of the LTE signal is above the ED level and that the channel is a secondary Wi-Fi channel for the access point, adapting spectrum allocation for the access point to avoid the channel;
- upon determining that the LTE signal is not a signal with an energy below the ED level on the primary Wi-Fi channel and is not a signal with an energy above the ED level on the secondary Wi-Fi channel, performing no link rate adaption in response to the LTE signal.
