1. A first wireless device comprising:
a network interface to communicate using a frequency bandwidth with multiple wireless devices, wherein the frequency bandwidth comprises a primary band, a first secondary band and a second secondary band, each of which correspond to different spectrum regions of the frequency bandwidth; and
at least one processor operatively connected to the network interface and configured to concurrently transmit a first, second and third trigger frame messages for each of the multiple wireless devices within respective trigger frame frequency bands of the frequency bandwidth to trigger respective first, second and third devices of the multiple wireless devices to concurrently transmit respective data units to the first wireless device within respective first, second and third frequency segments of the frequency bandwidth that are respectively within the primary band, first secondary band and second secondary band,
wherein the processor is configured to, prior to transmitting the trigger frame messages, transmit a channel announcement message for the multiple wireless devices, the channel announcement indicating that the first, second and third trigger frame messages have respective trigger frame frequency bands that are all within the primary band.
