Abstract
An apparatus and method is provided for configuring a sector in a multi-antenna mobile communication system. A cell is divided into a plurality of sectors, and a plurality of beams are formed for each of the divided sectors. The formed beams are allocated to the sectors in such a manner that a first beam of a second sector is spatially adjacent to a first beam of a first sector, so a plurality of beams allocated to one sector are spatially discontinuous and adjacent beams are formed for different sectors.

A method for configuring a sector in a wireless communication system, the method comprising the steps of:
- dividing a cell into a plurality of sectors, and forming a plurality of beams for each of the divided sectors;
- and
- allocating the formed beams to the sectors in such a manner that a first beam of a second sector is spatially adjacent to a first beam of a first sector, so a plurality of beams allocated to one sector are spatially discontinuous and adjacent beams are formed for different sectors.
A method for configuring a sector in a wireless communication system, the method comprising the steps of:
- generating a beam coefficient for each individual angle previously set according to a system environment;
- mapping beams to sectors, and generating a mapping table including beam allocation information for each sector;
- after generating the mapping table, forming a beam using the beam coefficient for each individual angle;
- selecting a specific beam with the highest power for the formed beam;
- searching the mapping table for information mapped to the selected beam;
- if there is an available resource for the corresponding beam, allocating the available resource to each channel element;
- and
- causing the channel element to perform channel processing using the allocated available resource.
A method for allocating resources in a multi-antenna communication system, the method comprising the steps of:
- upon receiving access channel information from a mobile station (MS), analyzing information on a beam formed for the MS and selecting a beam with the highest power;
- searching for sector information and beam information for the selected beam;
- allocating an available resource in the corresponding beam according to the searched information;
- and
- transmitting information on the allocated resource to a channel element.
A base station (BS) apparatus in a multi-antenna communication system, the apparatus comprising:
- a beamforming device for forming a plurality of beams for each of a plurality of sectors, and allocating the formed beams to each of the sectors such that the same sector includes a plurality of discontinuous beams;
- a resource allocator for providing mobile stations (MS) located in different beams in the same sector with the same resource;
- and
- a channel element for processing each channel using information on the resource allocated for each channel by the resource allocator.
