Methods for sending small packets in a peer-to-peer (P2P) network
First Claim
1. A method operational in a third device having a peer-to-peer connection with a fourth device to facilitate interference management for a second peer-to-peer connection between a first device and a second device within a wireless network, comprising:
- determining a signaling format to be used for a traffic signal to be sent to the fourth device, the signaling format being one of at least Gaussian signaling format and flash signaling format;
sending a transmission request signal to the fourth device in a transmission request resource;
monitoring a transmission request response resource to receive a transmission request response from the second device, the transmission request response from the second device indicating that the second device is prepared to receive a traffic signal from the first device different from the third device;
calculating an interference cost to the second device as a function of the determined signaling format; and
determining whether to send the traffic signal to the fourth device based on the calculated interference cost, the traffic signal to be sent in a traffic slot corresponding to the transmission request signal.

Abstract
An improved mechanism is provided that facilitates transmission of small packets within an ad hoc peer-to-peer network. A small packet is identified to a receiver within a control channel so that its lower power can be considered in an interference management protocol implemented among local peer devices. In a traffic slot, a transmitter voluntarily backs down on the transmitter power as a smaller packet will require much lower signal-to-noise ratio. This will improve the signal energy per bit per noise power density for the transmission as well as minimize the interference caused to other wireless communications happening in the same spectrum.
