摘要： 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.

摘要： 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.
摘要翻译：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。

摘要： Techniques for using user equipment, UE, activity information, e.g., by a network node in a communications network are described. The network node can obtain the UE activity information, i.e., information associated with at least one of transmission activity and reception activity for a UE, and then use the UE activity information to configure a positioning function. Some examples of the positioning function are positioning method selection, measurement configuration and assistance data provisioning, reserving positioning resources, stopping the positioning session, delaying handover of the UE, deciding on a position session organization such as number of parallel measurements to be performed, and estimating an impact on battery lifetime.

摘要： A user equipment (UE) performs measurements on a serving cell and at least one neighbor cell in a heterogeneous wireless communications network that includes one or more higher power radio network nodes operating near one or more lower power radio network nodes. The UE acquires enhanced neighbor cell information (eNCI) including at least subframe information and determines an allowed set of one or more subframes during which the UE may make downlink and/or uplink measurements for at least one cell in the heterogeneous network. A network node in the heterogeneous network generates the eNCI, from which the UE may determine the allowed set of radio transmission subframes, and provides the eNCI for the UE to coordinate the UE measurements on the at least one cell during one or more of the allowed subframes.

摘要： The invention relates to methods and devices for supporting configuration of a measurement gap pattern for a user equipment (91) requiring measurement gaps for performing an inter-frequency measurement. A radio network node (81) receives an indication (85) from the user equipment (91) that the user equipment (91) is going to perform an inter-frequency measurement for positioning, which inter-frequency measurement requires measurement gaps. The radio network node (81) may determine a measurement gap pattern for performing the inter-frequency measurement and may signal, to the user equipment (91), information (86) to initiate use of the determined measurement gap pattern in the user equipment (91). Alternatively the user equipment (91) configures the measurement gap pattern itself based on a set of pre-defined rules.

摘要： A first radio network node (HBS1) adapts its physical cell identifier (PCI1) based on a comparison of its PCI1 to a second PCI (PCI2) used by a neighboring interfering second radio network node (e.g., another HBS2 or a macro node). The first radio network node HBS1 determines the second PCI based on one or more radio measurements performed on a cell 402 and/or on a UE 404 served by the second node. The adaptation of the cell identifier PCI1 is used for one or more radio network management tasks, e.g., resource management such as interference mitigation in a heterogeneous network, radio network planning, etc.

摘要： A node of a multi-radio access technology (RAT) system acquires resource status information associated with each RAT of the multi-RAT system. The resource status information of the RATs of the multi-RAT system can be acquired by sniffing higher layer protocol information pertaining to call setup requests and/or call terminated messages. The node further maintains a flag representing overall resource availability associated with the RATs of the multi-RAT system, based on the acquired resource status information, for use in admission control and/or load balancing. The flag is associated with a pre-defined set of overall resource availability states of the multi-RAT system, where the availability states are defined in terms of admission control decisions. The availability states comprise at least one of the following admission control decisions: i) unconditional acceptance of all services; ii) conditional acceptance of broadband guaranteed bit rate (GBR) services and unconditional acceptance of all other services; iii) conditional acceptance of broadband GBR services, conditional acceptance of narrowband GBR services, and unconditional acceptance of other services; or iv) unconditional rejection of all services.
