<p>A method of transmitting in a second mode at least one data frame from a first node to a second node. Determining if there is data to be transmitted and if there is no data to be transmitted then transmitting from said first node to said second node no frame in the second mode. The first node receiving an indication that the first node should use a first mode and transmitting an acknowledgement in response to the indication. Switching from the second mode to the first mode and transmitting in the first mode at least one data frame from the first node to the second node. Then, further determining if there is data to be transmitted and if there is no data to be transmitted then transmitting from said first node to said second node at least one empty frame in the first mode.</p> |
