    • The present invention provides a method and apparatus for autonomously detecting whether a reference signal within an OFDM signal transmitted by a remote transmitter is or is not muted for a given transmission time. Muting or puncturing may be applied to all or only a portion of the reference signal. The method, which may be carried out in an appropriately configured radio apparatus, includes receiving the OFDM signal and calculating a first comparison metric from signal samples of the OFDM signal corresponding to a first set of resource elements of the OFDM signal, and calculating a second comparison metric from signal samples of the OFDM signal corresponding to a second set of resource elements of the OFDM signal. The method continues with determining whether the reference signal is or is not muted for the given transmission time, by comparing the first and second comparison metrics, and foregoing or performing reference signal measurements responsive to determining that the reference signal is or is not muted.

    • In its various aspects, the present invention addresses the many challenges associated with making timing measurements involving multifarious radio links. Such measurements are referred to herein as “enhanced” to connote that such timing determinations are being made across multifarious radio links. Here, a radio link will be understood as connecting two radio nodes, and two radio links are considered to be multifarious with respect to each other if they are opposite in terms of uplink and downlink transmit directions, and further if they are associated with different cell identifiers and/or if the two links are between different pairs of radio nodes. In this context, the teachings herein disclose the sharing of “enhanced timing measurement” capability information, e.g., between radio nodes and positioning nodes. Such information indicates the enhanced timing measurement capability of a radio node. Sharing such information enables another node, e.g., a positioning node, to determine an enhanced timing measurement configuration to be used by a radio node. Further, additional teachings herein disclose advantageous configurations for making enhanced timing measurements, and techniques for compensating timing measurements determined from multifarious radio links, e.g., compensating for frequency-dependent propagation time differences.
    • 在各方面,本发明解决了涉及多个无线电链路的定时测量相关的许多挑战。 这样的测量在本文中被称为“增强”,以表明正在通过多种无线电链路进行这样的定时确定。 这里,无线电链路将被理解为连接两个无线电节点,并且如果两个无线电链路在上行链路和下行链路传输方向上相反,则认为两个无线电链路相对于彼此是多重的,并且如果它们与不同的小区相关联 标识符和/或如果两个链路在不同的无线电节点对之间。 在这种情况下,本文的教导公开了例如在无线电节点和定位节点之间共享“增强的时序测量”能力信息。 这样的信息表示无线电节点的增强的定时测量能力。 共享这样的信息使得另一个节点,例如定位节点能够确定由无线电节点使用的增强的定时测量配置。 此外,本文的另外的教导公开了用于进行增强的时序测量的有利配置,以及用于补偿从多种无线电链路确定的定时测量的技术,例如补偿频率相关的传播时间差。
