Abstract  Abstract

PROBLEM TO BE SOLVED: To provide an improved application of signal strength weighting in an SDMA sectorized cellular network.

SOLUTION: The improved signal strength weighting application is conducted through improved selection of weighting from a new codebook subset or by selection of weighting from a larger codebook subset. In a further embodiment an antenna beam index or bit map can be used to select the best beam(s) in an SDMA sectorized cellular network. In another embodiment a field or factor in an uplink or downlink transmission packet can designate which directional transmission beam is best suited for the transmission or when the directional transmission beam should be activated.
