Reducing shared downlink radio channel interference by transmitting to multiple mobiles using multiple antenna beams

Abstract

And a plurality of antennas associated with the wireless base station the cell. A plurality of wireless mobile phone is selected to receive a transmission over a shared radio channel during a predetermined time interval. The information is transmitted via a shared radio channel to a plurality of wireless mobile telephone in a cell using a plurality of antenna beams for a predetermined time interval. As a result, interference from the transmission appear as white Gaussian noise added to the time and distance in the cell. Is caused by the single beam transmission over the shared channel for a predetermined time interval, in general, adversely affects the channel quality to the mobile phone determines "flash effect" are prevented. Another way to avoid the glare effect is described.Sharing the radio channel, the antenna, interference, transmission beam, glare effect
