Abstract: 무선 통신 시스템에서 용량을 증가시키는 기법들이 제시된다. 일 양상에서, 무선 통신 시스템에서 전송되는 최소-레이트 프레임들의 계통적 비-전송, 또는 "블랭킹"이 제공된다. 예시적인 실시예에서, cdma2000 음성 통신 시스템에서 1/8 레이트 프레임들은 제로(zero) 트래픽 비트들을 운반하는 널-레이트 프레임들로 계통적으로 대체된다. 그럼에도 불구하고, 공급들은 예컨대 보코더에 의해 "결정적인(critical)"으로 지정되는 특정한 전송에 의해 수행된다. 오직 비-널 레이트 프레임들에 응답하여 외부 루프 전력 제어를 갱신하는 것을 포함하는 상기 수신기는 널 레이트 또는 비-널 레이트 전송들의 존재를 탐지하고 수신된 프레임들을 적절히 프로세싱한다. 수신기가 널 레이트 프레임들을 탐지하는 것을 보조하도록 파일럿 전송 게이팅 패턴에 대한 추가적인 기법들이 제공된다. 다른 양상에서, 무선 통신 링크를 통한 신호 전송의 조기 종료가 제공된다. 예시적인 실시예에서, 될 수 있는 한 프레임의 모든 전력 제어 그룹들(PCG들)이 순방향 링크(FL)를 통해 수신되기 전에, 프레임의 정확한 수신이 역방향 링크(RL)를 통해 이동국(MS)에 의해 인식될 때까지 기지국(BS)은 FL을 통해 프레임에 대한 PCG들을 MS로 전송한다. 가능한 ACK 시그널링 방법들은 cdma2000 무선 통신 시스템과 관련된 채널들에 대하여 정의된다. 다른 예시적인 실시예에서, 역방향 링크 조기 종료에 대한 기법들이 또한 제공된다.

Abstract: PROBLEM TO BE SOLVED: To estimate reverse link loading in a wireless communication system.SOLUTION: The reverse link interference is measured and reverse link receiver noise is measured. The reverse link interference is compared to the reverse link receiver noise by dividing the interference power by the receiver noise power. The reverse link receiver noise is measured in an OFDMA system by nulling transmission from access terminals within a cell and nearby during a null time and frequency interval. To measure the reverse link interference, local null time and frequency intervals are designated, the access terminals within the cell null their transmissions during the designated local null time and frequency intervals, and interference power is measured in the local null time and frequency intervals. Alternatively, the interference power is measured by subtracting pairs of pilot symbols that are contiguous to each other in time or frequency.
Abstract translation: 要解决的问题：估计无线通信系统中的反向链路负载。解决方案：测量反向链路干扰，并测量反向链路接收机噪声。 通过将干扰功率除以接收机噪声功率，将反向链路干扰与反向链路接收机噪声进行比较。 反向链路接收机噪声在OFDMA系统中通过在空时间和频率间隔内对来自小区内和附近的接入终端进行归零来测量。 为了测量反向链路干扰，指定局部零时间和频率间隔，小区内的接入终端在指定的本地零时间和频率间隔期间使其传输失效，并且在本地零时间和频率间隔中测量干扰功率。 或者，通过在时间或频率上减去彼此连续的导频符号对来测量干扰功率。

Abstract: PROBLEM TO BE SOLVED: To provide a method for adaptive server selection in a wireless communication. SOLUTION: An access terminal may be configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the access terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced. COPYRIGHT: (C)2011,JPO&INPIT
