Description

System and method for managing power usage The present application claims the priority and benefit of U.S. provisional application No. 62/989,422 entitled "multilink power saving" filed on day 13 of 2020 and U.S. non-provisional patent application No. 17/159,760 entitled "systems and methods for managing power use" filed on day 27 of 2021, the entire contents of both of which are incorporated herein by reference. Technical Field One or more aspects in accordance with embodiments of the present disclosure relate to wireless networks, and more particularly to managing power usage of a multi-link device configured to receive and transmit data frames over multiple radio links. Background The wireless communication may occur via one or more communication channels of a wireless network. The wireless communication may conform to a wireless network protocol, such as, for example, an Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of protocols for Wi-Fi devices. The wireless network protocol may allow a device to transmit data over a wireless network using multiple (e.g., two or more) radio links. Devices using multiple radio links may consume more power than devices using a single link. Accordingly, it is desirable to manage power consumption of devices using multiple radio links.
