Abstract  Abstract

The present invention provides an improved application of signal strength weights in an SDMA sectored cellular network. Enhanced signal strength weighting is performed either through an improved selection of weights from the new codebook subset or by selection of weights from a larger codebook subset. In a further embodiment, the best beam (s) may be selected in an SDMA sectored cellular network using an antenna beam index or bitmap. In another embodiment, the field or factor in the uplink or downlink transmission packet may indicate which directional transmission beam is most suitable for transmission or when the directional transmission beam should be activated.
