TDD 기반 OFDMA 시스템에서 셀 외부 이동국에 대한 간섭 신호를 억제할 수 있는 다운링크 빔포밍 가중치가 도입되었습니다. 첫째, 다운링크 빔포밍 가중치는 반복을 기반으로 최적으로 설계됩니다. 그런 다음 다운링크 빔형성 가중치가 최적이 아닌 방식으로 설계됩니다. 차선적으로 설계된 하향링크 빔포밍 가중치는 MMSE를 기반으로 도출된 상향링크 빔포밍 가중치와 동일한 구조를 갖는 것을 나타낸다. 이러한 방식의 성능은 평균 수신 SINR을 기준으로 비교됩니다. 다운링크 빔포밍 가중치에 대해 업링크 빔포밍 가중치를 활용하는 휴리스틱 기법의 성능도 조사됩니다.

Abstract: The downlink beamforming weights which can suppress interfering signals toward out-of-cell mobile stations for a TDD-based OFDMA system are introduced. First, the downlink beamforming weights are optimally designed based on iteration. Then, the downlink beamforming weights are designed in a sub-optimal way. It is shown that the sub-optimally designed downlink beamforming weights have the same structure as that of the uplink beamforming weights which are derived based on MMSE. The performance of these schemes is compared based on the average receive SINR. The performance of a heuristic scheme which exploits uplink beamforming weights for downlink beamforming weights is also investigated.
