摘要： The number of Reverse Activity Bits (RABs) equal to “1” per frame is a Congestion Overload (CO) metric used to determine whether the reverse link in a wireless communications system is in a congestion overload state due to a reverse link RF overload. When the value of the CO metric exceeds a first predetermined threshold that is indicative of a congestion overload condition, the system enters a block state where all new connection requests are blocked. Once in the block state, if the value of the CO metric does not decrease but continues to increase and exceeds a second higher threshold, the system enters a mute state. In the mute state a predetermined large percentage of existing active calls are muted. Specifically, a message is sent downlink to specific ATs instructing them to reduce their transmission rates to zero but to still maintain their active connections.
摘要翻译：每帧相当于“1”的反向活动位数（RAB）是拥塞过载（CO）度量，用于确定由于反向链路RF过载，无线通信系统中的反向链路是否处于拥塞过载状态。当CO度量的值超过指示拥塞过载状况的第一预定阈值时，系统进入阻塞所有新连接请求的阻塞状态。一旦处于阻塞状态，如果CO度量的值不降低但是继续增加并超过第二高阈值，则系统进入静音状态。在静音状态下，预定的大部分现有活动呼叫被静音。特别地，向特定AT发送下行链路的消息，指示它们将它们的传输速率降低到零，但仍然保持其活动连接。

摘要： Methods and devices for performing role change are described. Dynamic signaling is used. Example formats for uplink and downlink signaling is also described. In some examples, an electronic device (ED) receives, via dynamic signaling, from a first serving cell, with which the ED initially has a primary connection, a role change trigger. The role change trigger causes the ED to use a connection with a second serving cell, with which the ED initially has a secondary connection, as the primary connection instead of the first serving cell.

摘要： In a 3G cellular network, a Reverse Link Channel Quality Indicator Channel (R-CQICH) may be transmitted on a reverse link to support forward link high-speed data transmissions. Accordingly, the R-CQICH may be utilized to track the quality of the signal path between the wireless unit and the base station. The base station may include a CQI component that utilizes a received Channel Quality Indicator (CQI) signal from the wireless unit to generate CQI quality metrics based on the quality of the received signal. Also, the CQI quality metrics may be compared to different thresholds to adjust various system configurations in the base station. The base station may also provide feedback to the wireless unit with the updated system configurations. This technique allows CQI quality metrics to be utilized to adjust system configurations dynamically and enhance the operation of a wireless system.

摘要： A method is provided a wireless system for providing an interference suppression zone in a portion of the macro cell coverage area bordering the small-cell coverage area for a small cell, but outside that small-cell coverage area. The transmission power of a UE located within the interference suppression zone is minimized to minimize the inter-cell interference to the small cells. The invention methodology further operates to enhance the redirection/redistribution methods of the art for UEs located in the interference suppression zone, further reducing macro to small cell interference. In further embodiments of the invention, methods are provided for determining the scope of an interference suppression zone and for determining proximity of an UE to the interference suppression zone.
