Abstract: 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.

Abstract: A radio base station generates a congestion status flag, based on measured resource usage in its cell, and based on performance of sessions in the cell. The flag may be a one bit, or a small number of bits, indicating whether the base station is congested. The flag can be sent to neighboring radio base stations, for use in determining whether to perform handovers to that radio base station. The flag generated in a radio base station, and the flags generated in neighboring radio base stations, can also be sent to user equipment in a cell.

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a method, a base station and an interface for handover in a wireless communication network. Handover is initiated when the signal quality falls below a predetermined value. Random access serves as an uplink procedure to enable the UE to make handover from a first base station (eNodeB) to a suitable second base station (eNodeB). In the present invention, random access parameters are exchanged between second and first base station before said first base station signals said random access parameters to said user equipment.

Abstract: Methods and apparatus for scheduling link resources in a wireless communication system are disclosed. In an exemplary method, a first scheduling policy vector, or SPV, is generated, the SPV including scheduling elements that prescribe a probability of use for each of several corresponding quantities of link resources. In some embodiments the link resources are LTE resource blocks. The SPV is transmitted to a mobile terminal for use in determining a quantity of link resource units to be scheduled in at least a first transmission time interval. The SPV may be transmitted along with a scheduling window parameter that specifies a period of applicability for SPV.

Abstract: A method of supporting frequency-selective repeaters (eNodeRs) in a wireless telecommunication system. A base station (eNodeB) classifies User Equipments (UEs) into two categories or lists of users: a white list containing UEs that may need the assistance of repeaters, and a black list containing UEs that do not need repeater assistance. The eNodeB transmits one of these two lists to the eNodeRs. The eNodeRs do not amplify resource blocks (RBs) scheduled for black list UEs. Each repeater may decide on its own whether to amplify signals for a non-black list UE by measuring signals from the UE and comparing them with predefined criteria.

Abstract translation: 一种在无线电信系统中支持频率选择中继器（eNode-RR）的方法。 基站（eNodeB）将用户设备（UE）分为两类或用户列表：包含可能需要中继器协助的UE的白名单，以及包含不需要中继器协助的UE的黑名单。 eNodeB将这两个列表中的一个发送到eNodeR。 eNodeR不放大为黑名单UE调度的资源块（RB）。 每个中继器可以自己决定是否通过测量来自UE的信号并将其与预定标准进行比较来放大非黑名单UE的信号。
