Abstract:
예컨대, 애드 혹 피어 투 피어 네트워크와 같은 모바일 무선 시스템에서 피어/네트워크/서비스 발견과 관련된 방법들 및 장치들이 설명된다. 예컨대, 상위 계층 발견 정보와 같은 발견 정보의 전송은 시간에 따라 개별적으로 전송될 다수의 부분들로 나누어진다. 각각의 부분들의 전송은 피어 발견 전송들의 주파수에 있어서 유연성(flexibility)뿐만 아니라 이러한 전송들의 모니터링을 가능하게 하도록 구조화된다. 다양한 실시예들은 예컨대, 신뢰성있는 피어들에 의한 선택적 발견과 같은 고속(rapid) 발견 및/또는 보안 발견을 용이하게 한다. 상기 구조화는 예컨대 지원 노드와 같은, 제 3 자에 의한 몇몇의 전송들의 프록싱(proxy)을 가능하게 한다. 상기 지원 노드는 제 1 레이트에서 통신되는 발견 정보 부분들을 수신하고 제 1 레이트보다 높은 제 2 레이트에서 수신된 발견 정보 부분들을 재전송한다.

Abstract:
PROBLEM TO BE SOLVED: To support multiple communication channels corresponding to different communication technologies and/or access technologies in parallel within a cell of a wireless communications system. SOLUTION: Mobile nodes support multiple technologies and can switch between the technology being used at a particular point of time, e.g., from a first channel corresponding to a first technology to a second channel corresponding to a different technology which provides better transmission characteristics, e.g., a better perceived channel quality. Mobiles maintain at least two sets of channel quality information at any one point of time. Mobiles select the better channel and communicate the channel selection to a base station or communicate channel quality information for multiple channels to the base station and allow the base station to select the channel corresponding to the technology providing the better conditions for the mobile. Different mobiles in the same cell may support different technologies. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide pilot signal transmission sequences and methods for use in a multi-sector cell. SOLUTION: Pilots in different sectors are transmitted at different known power levels. In adjacent sectors, a pilot is transmitted while no pilot is transmitted in the adjoining sector. This represents transmission of a null pilot signal. A cell null is also supported, in which null pilots are transmitted in each sector of a cell at the same time. Measurements of multiple pilot signals are performed. At least two channel quality indicator values are generated from measurements corresponding to at least two pilot signals of different power levels. Two values are transmitted back to a base station which uses both values to determine the transmit power required to achieve a desired SNR at the wireless terminal. The wireless terminal also reports information indicating its location to a sector boundary. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a wireless terminal to be used for communication with a base station in a communication system including a plurality of base stations. SOLUTION: The wireless terminal includes storing base station position information in a memory; receiving a signal from the first base station; determining a time for transmitting an access signal to the second base station, based on the stored position information indicating the position of the first base station to which a signal to be received by the wireless terminal is transmitted; and transmitting the access signal at a determined time.
