Abstract: The invention involves data processing during intra-site handover procedures. At least two directional antennas (140; 160) of a base station (100) receive user data carrying signals originating from a mobile units (400) positioned in an intra-site handover area (15) defined by the overlapping radio coverage (14; 16) of the antennas (140; 160). The directional antennas (140; 160) performs an initial data signal detection of the received data signals resulting in detected user data, which typically results in a loss of radio performance of the antenna (140; 160). The detected user data from the directional antennas (140; 160) is then jointly processed to generate processed user data. The performance loss is compensated by providing differential antenna gain of the directional antennas (140; 160) within the handover area (15). As a result, a similar radio coverage in this area (15) as prior art solutions is obtained but with a less complex antenna-related design. ® KIPO & WIPO 2007

Abstract: A method and apparatus for providing handover between carriers of different duplex frequency separation distances is provided. A mobile terminal is configured to operate in both fixed and variable duplex. The ability operate with unpaired up-link and down-link frequency carrier pairs, when necessary, makes it possible to significantly increase the spectrum utilization (capacity) in a cellular system using asymmetric up-link and down-link for example in WCDMA systems.

Abstract: 상이한 듀플렉스 주파수 분할 거리의 캐리어들 간에 핸드오버를 제공하는 방법 및 장치가 제공된다. 이동 단말기는 고정 및 가변 듀플렉스 둘 다에서 동작하도록 구성된다. 이 성능은 필요한 경우 쌍을 이루지 않는 업링크 및 다운링크 주파수 캐리어로 동작하여, 예를 들어 WCDMA 시스템에서 비대칭 업링크 및 다운링크를 사용하여 셀룰러 시스템에서 스펙트럼 이용도(용량)를 크게 증가시킬 수 있다.
