Abstract

A method includes obtaining a first packet at a first wireless device from a second wireless device. The second wireless device may be a neighboring wireless device of the first wireless device. The method may also include transmitting a second packet to a third wireless device that is a neighboring wireless device of the first wireless device. The method may also include obtaining a third packet from the third wireless device in response to transmitting the second packet to the third wireless device and obtaining a fourth packet from the third wireless device in response to the third wireless device receiving a fifth packet from a fourth wireless device that is not one of the multiple neighboring wireless devices of the first wireless device. The fourth packet may indicate reserved radio resources for future packet transmissions from the first wireless device to the third wireless device.
