Abstract
A wireless device may include a transceiver configured to communicate through a first link and a second link. The wireless device may be configured to indicate, through the transceiver, a number of spatial streams associated with the first link. The wireless device may include one or more radio frequency (RF) chains and may be configured to indicate a sharing capability of the one or more RF chains between the first and second links. The wireless device may be configured to perform a collision avoidance operation based on switching an RF chain from the first link to the second link. The wireless device may be configured use an RF chain on the first link based on the availability of the first link. A method of performing a sounding operation may include initiating a sounding sequence on a link based on a sounding feedback capability of a wireless device.
