Abstract
Techniques for wireless communications are disclosed. These techniques include identifying a change in at least one of: (i) a WiFi radio channel or (ii) a cellular radio channel for a wireless station (STA) supporting both WiFi and cellular radio access technologies. The techniques further include determining one or more WiFi radio channels subject to interference from the cellular radio for the STA, based on a network message received from the STA, and modifying one or more parameters for WiFi communication relating to the STA, based on the determined one or more WiFi radio channels subject to interference.
Claims17
A method, comprising:
- identifying, by an access point (AP), a change in at least one of:
- (i) a WiFi radio channel or (ii) a cellular radio channel for a wireless station (STA) supporting both WiFi and cellular radio access technologies;
- determining, by the AP, one or more WiFi radio channels subject to interference from the cellular radio for the STA, based on a network message received from the STA, wherein the network message comprises an event report action frame that identifies the one or more WiFi radio channels subject to interference;
- and
- modifying, by the AP, one or more parameters for WiFi communication relating to the STA, based on the determined one or more WiFi radio channels subject to interference.
A system, comprising:
- a processor;
- and
- a memory having instructions stored thereon which, when executed on the processor, performs operations comprising:
- identifying a change in at least one of:
- (i) a WiFi radio channel or (ii) a cellular radio channel for a wireless station (STA) supporting both WiFi and cellular radio access technologies;
- determining one or more WiFi radio channels subject to interference from the cellular radio for the STA, based on a network message received from the STA, wherein the network message comprises a list relating to preferred WiFi channels, and wherein determining the one or more WiFi radio channels subject to interference is based on the list;
- and
- modifying one or more parameters for WiFi communication relating to the STA, based on the determined one or more WiFi radio channels subject to interference.
A non-transitory computer-readable medium having instructions stored thereon which, when executed by a processor, performs operations comprising:
- identifying a change in at least one of:
- (i) a WiFi radio channel or (ii) a cellular radio channel for a wireless station (STA) supporting both WiFi and cellular radio access technologies;
- determining one or more WiFi radio channels subject to interference from the cellular radio for the STA, based on a network message received from the STA;
- determining a number of STAs for which the one or more WiFi radio channels are subject to interference;
- and
- modifying one or more parameters for WiFi communication relating to the STA, based on the determined one or more WiFi radio channels subject to interference and the determined number of STAs.
