Title:
DATA TRANSFER METHOD
Document Type and Number:
WIPO Patent Application WO2001078220
Kind Code:
A8
Abstract:
A data transfer method in a radio system comprising a first transceiver and a second transceiver. The first transceiver comprises a multiple antenna system. A signal transmitted by the first transceiver is measured by the second transceiver. A parameter value representing the quality of the signal measured by the second transceiver from the signal it received is compared with given threshold values, and thus a quality class for the performance of a channel is determined. The second transceiver codes the determined quality class and transmits information to the first transceiver. The transmit parameters of the antenna elements of the first transceiver are determined for transmission based on the quality class information.
