Abstract: A base station may calculate a scheduling value based on at least one of a number of groups associated with a set of UEs operating on a cell provided by the base station a radio frame number, or a subframe number. The base station may send, based on the calculated scheduling value, at least one NRS in at least one PO on a narrowband control channel. A UE may receive, from the base station providing the cell, information associated with at least one PO for the UE. The UE may determine, based on the received information, scheduling information associated with at least one NRS in the at least one PO. The UE may detect the at least one NRS in the at least one PO on a narrowband control channel when the determined scheduling information indicates the at least one NRS is in the at least one PO.

Abstract: Determining the early arrival path (EAP) based on a channel energy response (CER) can involve the use one or more masks to identify one or more peaks in the CER. Masks can be applied to the CER in an iterative process that can help identify the earliest peak corresponding to the EAP. Alias cancelation may also be implemented.

Abstract: A method for blindly determining positioning reference signals in a wireless communication network determines a positioning reference signal (PRS) network configuration by estimating a PRS energy from predetermined locations of each subframe of an incoming signal. Such a method may also include blindly detecting PRS parameters based on the estimated PRS energy. The PRS energy may be peak energy responses for deep searches or verifications. The PRS energy may be a signal to signal plus noise ratio for shallow searches.

Abstract translation: 一种用于在无线通信网络中盲目确定定位参考信号的方法通过从输入信号的每个子帧的预定位置估计PRS能量来确定定位参考信号（PRS）网络配置。 这种方法还可以包括基于估计的PRS能量盲目地检测PRS参数。 PRS能量可能是深度搜索或验证的峰值能量响应。 PRS能量可以是浅层搜索的信号加信噪比。

Abstract: A method of providing Observed Time Difference of Arrival (OTDOA) assistance information to a mobile station is disclosed. In some embodiments, the OTDOA assistance information may comprise Positioning Reference Signal (PRS) assistance information including antenna switching assistance information for at least one cell. In one embodiment, the method may be implemented on a location server for the cell.
