1. A computer-implemented method, comprising:
receiving, by a second wireless communication node from a first wireless communication node, a notification frame;
receiving, by the second wireless communication node from the first wireless communication node, data to be transmitted to a wireless communication device;
performing a joint transmission, by the second wireless communication node with the first wireless communication node, a joint transmission of the data to the wireless communication device, according to the notification frame received from the first wireless communication node;
receiving, by the second wireless communication node from the first wireless communication node, an identification of a set of frequency bands or channels to support the joint transmission; and
suspending, by the second wireless communication node, based on a transmission start time specified in the notification frame, a back-off counter by keeping a value of the back-off counter constant, wherein the back-off counter is associated with a plurality of access category queues of a transmission buffer storing the data to be transmitted by the second wireless communication node at a beginning of the joint transmission to the wireless communication device.
