METHODS FOR SENDING SMALL PACKETS IN A PEER-TO-PEER (P2P) NETWORK
First Claim
1. A method operational in a fourth device having a peer-to-peer connection with a third 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:
- monitoring to receive a first transmission request signal from the third device and a second transmission request signal from the first device, the first transmission request signal indicating that the third device intends to send a traffic signal to the fourth device in a traffic slot corresponding to the first transmission request signal and the second transmission request signal indicating that the first device intends to send a traffic signal to the second device in the same traffic slot, the second transmission request signal further including information indicative of the signaling format to be used in the traffic signal from the first device to the second device, the signaling format being one of at least a Gaussian signaling format and a flash signaling format;
recovering the information indicative of the signaling format from the second transmission request signal;
calculating an interference power as a function of the signal strength of the received second transmission request; and
determining whether to receive the traffic signal from the third device based on the calculated interference power.

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.
