Abstract: Apparatus and methods for low power sensing of wireless access technologies are disclosed. In particular, a mobile wireless device, such as an access terminal, may utilize a lower power circuitry portion that operates at a lower power than active circuitry, such as a primary transceiver. The lower power circuitry portion includes a configurable searcher that is capable of sensing if signals of one or more various wireless access technologies are present. When the wireless device utilizes sleep or idle modes for power savings, use of the lower power sensing circuitry to sense the presence of wireless access technologies, rather than using an awoken higher power primary transceiver for sensing, affords increased power savings. An added ability of the lower power circuitry to be put into sleep or idles modes achieves even greater power savings.

Abstract translation: 公开了用于无线接入技术的低功率感测的装置和方法。 具体地，诸如接入终端的移动无线设备可以利用比诸如主收发器的有源电路低的功率操作的较低功率电路部分。 较低功率电路部分包括能够感测是否存在一种或多种各种无线接入技术的信号的可配置搜索器。 当无线设备利用睡眠或空闲模式进行功率节省时，使用低功率感测电路来感测无线接入技术的存在，而不是使用唤醒的较高功率的主收发器来进行感测，从而提供更大的功率节省。 低功率电路进入睡眠或空闲模式的附加功能实现了更大的功率节省。
