Title: Constellation rearrangement for ARQ transmit diversity schemes

Abstract: An ARQ (re-) transmission method of transmitting data in a wireless communication system wherein data packets are transmitted from a transmitter to a receiver, using a first transmission and a second transmission based on a repeat request. The method comprises the steps of modulating data at the transmitter using a first signal constellation pattern to obtain a first data symbol. The first data symbol is transmitted as the first transmission to the receiver using a first diversity branch. Further, the data is modulated at the transmitter using a second signal constellation pattern to obtain a second data symbol. Then, the second data symbol is transmitted as the second transmission to the receive over a second diversity branch. Finally, the received first and second data symbol data symbol are diversity combined at the receiver. The invention further relates to a transmitter and a receiver embodied to carry out the method of the invention.

Disclaimer: Pseudo Claim Charting (PCC) conducts aggressive mapping (based on Broadest Reasonable, Ordinary or Customary Interpretation) between a target patent's claim elements and other documents (potential technical standard specifications or prior arts), therefore allowing for a top-down, apriori due diligence, with which, stakeholders can assess standard essentiality (potential strengths) or invalidity (potential weaknesses) quickly and effectively before making critical decisions. PCC is designed to relieve partial burden of proof by means of an exhaustive listing of potential building blocks towards a litigation-ready work product. Stakeholders may then narrow down and modify upon selected PCC to achieve further purposes.
