Title:
APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT PROVIDING PROTECTED FEEDBACK SIGNALING TRANSMISSION IN UPLINK CLOSED-LOOP MIMO
Document Type and Number:
WIPO Patent Application WO2008001192
Kind Code:
B1
Abstract:
A device configured to perform communication operations, the device having a transceiver and a control unit. The transceiver is configured to receive a signal incorporating scheduling grant and antenna weight feedback information from a remote receiver in a wireless communications system. The control unit is configured to verify correct receipt of the signal incorporating the scheduling grant and antenna weight feedback information and to use the antenna weight feedback information to control beamforming operations performed by the device when performing signal transmission operations. A computer program product composed of a computer readable memory medium storing a computer program. The computer program, when executed, is configured to cause a device to receive a signal incorporating scheduling grant and antenna weight feedback information from a remote receiver in a wireless communication system; and to verify correct receipt of the signal and to use the antenna weight feedback information to control beamforming operations performed by the device when performing signal transmission operations.
