Abstract:
1. A method of physical layer adaptation during operation of a wireless communication link using a protocol stack comprising: accepting data packets for transmission from an upper layer of the protocol stack wherein each data packet has an associated quality of service requirement specified by the upper layer; selecting a physical layer frame temporal duration and format for transmission of each data packet based on the associated quality of service requirement of the data packet; transmitting a plurality of control frames over the wireless communication link wherein the control frames each comprise control information to define the selected physical layer frame temporal duration and format for a following data frame, wherein transmitting the plurality of control frames comprises transmitting the control information on a first wireless channel; and transmitting a plurality of data frames over the wireless communication link each data frame comprising a corresponding packet and using the selected physical layer frame temporal duration and format for the packet, wherein transmitting the plurality of data frames comprises transmitting the packets on a second wireless channel, wherein the first wireless channel has a first frequency and the second wireless channel has a second frequency different from the first frequency.
