US 2011/0211488 A1 · TECHNIQUE FOR SIGNAL TRANSMISSION MODE DETERMINATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR SAME

Abstract

The present invention relates to a method for determining the transmission mode in a wireless communication system. More specifically, the present invention relates to a method for transmission mode determination in a wireless communication system, comprising a step wherein feedback information regarding channel status is received, and a step wherein it is determined based on said feedback information whether a transmission signal will be transmitted via each of a fixed number of subcarriers, after applying a propagation sequence.

Claims24

Dependent claims

A method for determining a transmission mode in a wireless communication system, the method comprising:

receiving feedback information about a channel state;
and
determining based on the feedback information whether to transmit a transmission signal on a subcarrier basis or to apply a spreading sequence to the transmission signal and transmit the transmission signal on a predetermined number of subcarriers basis.

Dependencies are inferred from the claim text.
