Abstract:
1. A method for cellular wireless communication, comprising: providing in each cell a set of first group radio transmitters that divide the cell into a set of first group sectors with one first group radio transmitter per first group sector; providing in each cell a set of second group radio transmitters that divide the cell into a set of second group sectors with one second group radio transmitter per second group sector, wherein the set of second group sectors are equal in number and in size to the set of first group sectors; arranging the first and the second radio group transmitters in each cell to overlap the first and second group sectors in a manner that the first group sectors are spatially shifted from and spatially interleaved with the set of first group sectors so that each first group sector spatially overlaps with two adjacent second group sectors and vice versa; assigning a set of sector radio bandwidth segments to the set of first group radio transmitters, respectively, to transmit to the set of first group sectors, respectively, wherein two adjacent first group sectors are assigned with different sector radio bandwidth segments; assigning the set of sector radio bandwidth segments to the set of second group radio transmitters, respectively, to transmit to the set of second group sectors, respectively, wherein two adjacent second group sectors are assigned with different sector radio bandwidth segments, and a first group sector and a second group sector that are assigned with the same sector radio bandwidth segment are spatially separate from each other without overlap; further operating each first group radio transmitter to transmit at a sector radio bandwidth segment to provide transmit diversity for a second group sector in the overlapped area of the two sectors; and further operating each second group radio transmitter to transmit at a sector group radio bandwidth segment to provide transmit diversity for a first group sector in the overlapped area of the two sectors.
