摘要： Techniques for performing searches by a user equipment (UE) equipped with multiple receive antennas are described. In an aspect, the UE may support multiple receive diversity (RxD) search modes. Each RxD search mode may be different from each remaining RxD search mode in how correlation is performed, how correlation results are combined, and/or how search results are reported for the multiple receive antennas. The UE may select an RxD search mode from among the multiple RxD search modes and may perform at least one step of a search in accordance with the selected RxD search mode. In another aspect, the UE may perform a search with interference cancellation to detect cell(s). The UE may determine multiple complex weights for multiple receive antennas such that signals from interfering cells can be attenuated. The UE may perform a search to detect cell(s) using the complex weights.
摘要翻译：描述了由配备有多个接收天线的用户设备（UE）执行搜索的技术。在一方面，UE可以支持多种接收分集（RxD）搜索模式。每个RxD搜索模式可以不同于每个剩余的RxD搜索模式，如何执行相关性，相关结果如何组合，和/或如何针对多个接收天线报告搜索结果。 UE可以从多个RxD搜索模式中选择RxD搜索模式，并且可以根据所选择的RxD搜索模式执行搜索的至少一个步骤。在另一方面，UE可以执行具有干扰消除的搜索以检测小区。 UE可以确定多个接收天线的多个复权重，使得可以衰减来自干扰小区的信号。 UE可以执行搜索以使用复权重来检测小区。

摘要： The present disclosure presents example methods and apparatuses for improved cell searching in a wireless communications environment. For example, the disclosure presents example methods that can include computing a predicted serving signal strength associated with a serving cell where a mobility state of a user equipment is one of a stationary state or a low mobility state. Furthermore, in an aspect, the example method can include ascertaining a search threshold based at least on the predicted serving signal strength and generating a search integration length based on at least the search threshold. In addition, some example methods may include scanning for one or more reselection candidate cells based on at least the search integration length, wherein each of the one or more reselection candidate cells has a cell signal strength greater than the search threshold.
