Document Type and Number:
WIPO Patent Application WO2002011311
Kind Code:
A3
Abstract:
Apparatus for and methods of receiving a transmission signal,suitable for use in a cellular mobile communications system,are disclosed. The apparatus comprises a beam former (50) forreceiving signals from a plurality of antenna elements, whichreceived signals represent the transmission signal, and formodifying the received signals in accordance with a receiverbeam pattern defined by control information input to the beamformer (50). The apparatus also comprises estimating means(54) for producing an estimate of desired control informationby combining predetermined data in the received signals with areplica of the predetermined data. The estimate of desiredcontrol information may be used to set the control informationinput to the beam former (50).
