1. A wireless device comprising:
a transceiver configured to communicate through a first link and a second link;
wherein the wireless device is configured to indicate, through the transceiver, a number of spatial streams associated with the first link;
wherein the transceiver comprises one or more radio frequency (RF) chains;
wherein the wireless device is further configured to indicate, through the transceiver, a sharing capability of the one or more RF chains; and
wherein a first field of the sharing capability indicates that the transceiver is capable of sharing at least one of the one or more RF chains between the first link and the second link, and a second field of the sharing capability indicates a number of RF chains the transceiver is capable of sharing between the first link and the second link; and
wherein the wireless device is further configured to initiate a first sounding sequence on the first link and initiate a second sounding sequence on the second link.
