Abstract
Devices and methods for observing characteristics of a wireless communication network environment and adjusting at least two different communication configuration parameters substantially at a same time based on the observed characteristics. The devices and methods may monitor radio resource measurements and initiate adaptive smarts for adjusting communication parameters of various protocol layers as a combination. Various other embodiments and features are also disclosed.
Claims21
A method of communicating comprising:
- observing characteristics of a wireless communication network environment;
- and
- adjusting at least two different communication configuration parameters substantially at a same time based on the observed characteristics;
- wherein one or more of the at least two different communication configuration parameters are associated with a media access control (MAC) layer and is selected from a group consisting of configuration parameters for access point (AP) selection, fragmentation size adaptation, data rate adaptation, request-to-send (RTS) clear-to-send (CTS) threshold adaptation, collision avoidance adaptation, power management adaptation, dynamic channel allocation and spectral reuse.
