Abstract: Various example implementations are provided to improve wireless resource usage in a device-to-device (D2D) wireless network. According to one example implementation, a first user device may transfer a wireless channel to another user device of the D2D user group before an end of a current channel holding period. The first user device may control sending a channel transfer notification. One or more other user devices may request transfer of the channel for a remaining portion of the current channel holding period by controlling sending a channel transfer request to the first user device. According to another example implementation, the first user device may control sending a channel holding period extension request to one or more other user devices of a device-to-device (D2D) user group to request that the first user device continue holding the wireless channel for a next channel holding period.
