Patent ID: 8432929

Claim:
A handoff method performed by a base station of a cellular communication system; the method comprising: generating an array of narrow beams by an antenna arrangement of the base station, wherein the array of narrow beams covers a sector, two adjacent beams of the array of narrow beams defining a spatial separation between the two adjacent beams, the array of narrow beams configured to allow an end user equipment located in the sector to discriminate between the two adjacent beams using only the spatial separation; transmitting different data traffic signals on each beam of the array of narrow beams simultaneously to a plurality of end user equipment; determining when a first end user equipment of the plurality of end user equipment is located in a high interference region between two adjacent beams of the array of narrow beams; and in response to such a determination, simultaneously transmitting data traffic to the first end user equipment on at least two beams of the array of narrow beams.
