Abstract: Embodiments of the present invention provide methods and devices for performing wireless sensing operations that can accommodate different Rx frequency responses with minimum PHY changes to increase the performance and reliability of wireless sensing in wireless local area network (WLAN) networks. Rx frequency response information can be obtained as channel state information (CSI) in a loopback test and can further be normalized with the total gain in the receiver chain leading to CSI estimation. Moreover, different Rx frequency responses can be categorized into limited groups with underlying circuit conditions based on their frequency response variations. The different Rx frequency responses can be indicated in subfields of a CSI report transmitted to the sensing initiator for performing sensing operations with the sensing responder.

Abstract: Various schemes pertaining to distributed-tone resource unit (RU) operation in 6 GHz low-power indoor (LPI) systems are described. A communication entity distributes frequency tones of a resource unit (RU) over a distribution bandwidth as a distributed-tone RU (dRU).

Alternatively, the dRU operation is implemented per frequency segment. Alternatively, the dRU co-exists with regular or localized RU.

Abstract: Power management operations are performed by devices communicating using multiple bands simultaneously where a first wireless band can be used to send and receive power management control frames for use on a second wireless band of a wireless network. In this way, a device that is in a sleep or dose power management state on a first band can be instructed to enter an awake power management state on the first band based on a communication received over a second band that is currently active and receiving data. Embodiments of the present invention enable power to be conserved when a band is not currently being used, or when there is no more data available (buffered) for a specific band.
