Methods for sending small packets in a peer-to-peer (P2P) network
First Claim
1. A method of operating a second wireless device having a connection with a first wireless device in a peer-to-peer communication network, comprising:
- monitoring to receive a pilot signal from the first device in a pilot channel associated with a data traffic slot;
determining a pilot format being used by the first device based on the received pilot signal;
determining a data traffic format to be used in the data transmission slot based on the determined pilot format;
calculating an interference power based on the determined pilot format and received pilot signal; and
determining a data rate based on the calculated interference power and the determined data packet format.

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.
