APPARATUS AND METHOD OF GENERATING AND MAINTAINING NON-ORTHOGONAL CONNECTION IDENTIFICATIONS (CIDs) FOR WIRELESS PEER-TO-PEER NETWORKS
First Claim
1. A method of operating a first device for generating and utilizing a connection identifier for a peer-to-peer communication connection between the first device and a second device in a wireless communications network, comprising:
- determining the connection identifier as a function of a first identifier of the first device and a second identifier of the second device;
obtaining a value of a time counter; and
transmitting traffic data to the second device in a traffic channel slot as a function of the connection identifier and the value of the time counter.

Abstract
Apparatus and method are provided for generating transmission connection identifiers (CIDs) in a non-orthogonal or pseudo-random manner identifying peer-to-peer connections in a wireless communication network. When a transmitter terminal intends to transmit to its peer receiver terminal, it just picks a transmission CID in a pseudo-random manner, without trying to avoid a similar transmission CID in a neighborhood. The method of generating this pseudo-random transmission CID may be agreed to between the transmitter and its intended receiver beforehand, for example, during the paging cycle. Also, the mapping between the transmission CID and a set of tone/symbols may not necessarily be orthogonal. In one embodiment, the transmission CID may also change over time in a pseudo-random fashion which is different between different transmitter/receiver pairs. With this property, two transmitter/receiver (Tx/Rx) pairs are not likely to use the same transmission CID for consecutive time intervals.
