1. A wireless device comprising:
- a processor, operatively coupled to a transceiver, configured to transmit and receive data, directly with other wireless devices, using carrier sense multiple access, and to receive, from at least one other wireless device of the other wireless devices, an indication of an operating mode of the at least one other wireless device for power saving, wherein the operating mode indicates times that the at least one other wireless device is available to communicate; and
the processor configured to transmit, via the transceiver directly to at least one of the other wireless devices, a message with scheduling information indicating times that the wireless device is awake, wherein the message includes variable duration information, and configured to determine sleep times based on the operating mode and the variable duration information.
