用于以多个接收分集(RXD)搜索模式执行搜索的方法及设备
摘要：
本发明描述用于通过配备有多个接收天线的用户设备UE执行搜索的技术。在一方面中，所述UE可支持多个接收分集RxD搜索模式。每一RxD搜索模式可在以下方面不同于每一其余RxD搜索模式：如何执行相关，如何组合相关结果，及/或如何报告所述多个接收天线的搜索结果。所述UE可从所述多个RxD搜索模式中选择一RxD搜索模式，且可根据所述所选择的RxD搜索模式执行搜索的至少一个步骤。在另一方面中，所述UE可执行具有干扰消除的搜索以检测小区。所述UE可确定用于多个接收天线的多个复权重，使得来自干扰小区的信号可被衰减。所述UE可使用所述复权重执行搜索以检测小区。
摘要（英）：

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.
