Supplemental cross-technology discovery

A method and an apparatus for wireless communication are provided. In one aspect, the apparatus may be a user equipment (UE), base station, or access point. The apparatus broadcasts peer discovery information in a high-level expression data structure that supports multiple discovery technologies from a variety of wireless networks. By using the high-level expression data, the apparatus may use a single, unified discovery application programming interface for signaling the presence of any supplemental cross-technology discovery information as such information became available. In another aspect, the apparatus may be a UE. The apparatus receives the broadcasted high-level expression data in a peer discovery signal and processes the data. 提供了用于无线通信的方法和装置。在个方面中，所述装置可以是用户设备(UE)、基站或者接入点。所述装置在支持来自多种无线网络的多个发现技术的高级表达式数据结构中广播对等点发现信息。通过使用所述高级表达式数据，所述装置可以使用单个、统的发现应用编程接口来在任何补充跨技术发现信息变得可用时用信号通知这样的信息的存在。在另个方面中，所述装置可以是UE。所述装置接收对等点发现信号中的所广播的高级表达式数据，并且对所述数据进行处理。
