1. A method for wireless communication by a wireless communication device, comprising:
determining that a first random back off (RBO) for a first channel of a first link has counted down to zero;
determining, when the first RBO has counted down to zero, that a second RBO for a second channel of a second link has a count down remaining;
determining to wait for the second RBO before transmitting on the first link, wherein determining to wait for the second RBO before transmitting on the first link includes:
resetting the first RBO to a new value in response to another device using the first channel; and
waiting for the first RBO and the second RBO to count down to zero after resetting the first RBO;
determining that the second RBO has counted down to zero; and
transmitting at least a first physical protocol data unit (PPDU) on the first link during a transmission opportunity (TXOP) that starts when the first RBO has counted down to zero.
