Abstract: A home base station (HBS) (104, 801) performs radio channel measurements to detect one or more user equipments (UEs) (107) not served by the HBS which may be in a potentially interfering environment caused at least in part by the HBS. A database (812) of historical channel data (channel fingerprinting) of the HBS coverage area is used to predict the channel conditions and expected interference signal power seen by the detected UE(s). Based on a combination of the radio measurements (813) and historical channel data, the HBS can accurately and adaptively reduce its transmit power to a level that reduces or eliminates interference with the detected UE(s), while also not significantly degrading communication quality between other UEs served by the HBS.

Abstract translation: 家庭基站（HBS）（104,801）执行无线电信道测量以检测不由HBS服务的一个或多个用户设备（107），所述HBS可能至少部分地由HBS引起潜在的干扰环境 。 使用HBS覆盖区域的历史信道数据（信道指纹）的数据库（812）来预测检测到的UE看到的信道状况和预期的干扰信号功率。 基于无线电测量（813）和历史信道数据的组合，HBS可以将其发射功率精确和自适应地降低到降低或消除对所检测到的UE的干扰的水平，同时也不会显着降低 由HBS服务的其他UE。

Abstract: A networks node generates an inter-frequency neighbor list of neighbor cells intended to be measured including neighbor cells satisfying an alignment condition and a sufficient measurement time. The alignment condition is satisfied when subframes of a first signal having a first frequency transmitted via a reference cell associated with the user equipment are synchronized with, have a known offset relative to or have a random offset smaller than one half of a sub frame relative to corresponding subframes of a second signal having a second frequency transmitted via a neighboring cells. The sufficient measurement time is determined by an overlap of measurement gaps and positioning subframes in the second signal. The user equipment performs the inter-frequency Reference Signal Time Difference (RSTD) measurements during measurement gaps.

Abstract: The invention relates to methods and arrangements for an event triggered DRX cycle adjustment. A user equipment located in a serving cell of a mobile communications network monitors downlink communication at predetermined time intervals when operating in discontinuous reception mode. The user equipment also performs communication parameter measurements regarding at least one of the serving cell and one or more neighbour cells. After the occurrence of a first event, the user equipment sends at least one of measurement data and a first event report to the network. The sending is triggered by the occurrence of the first event. The monitoring is caused to be performed at shortened time intervals after the occurrence of a second event, wherein the second event is defined to indicate a higher probability of receiving a handover command than the first event.

Abstract: A measuring node (700) in a wireless network (100) sets switching points for a plurality of measurement groups, performs measurements of signals transmitted from one or more cells corresponding to a group, and switches, at each switching point, from performing measurements according to one measurement group to performing measurements according to the next measurement group. The signals are transmitted by the cells in measurement occasions that repeat in a pattern. A switching point is a time by which the measuring node (700) node is expected to complete, at least in part, measurements of the one group and be ready to proceed with measurements of the next group. A configuring node (600) sends assistance data to the measuring node (700) to enable the measuring node (700) to determine the switching points for the measurement groups.

Abstract: A network node determines one or more parameters related to a Specific Absorption Rate (SAR) target, where SAR is a measure of a maximum energy or power absorbed by a unit of mass of tissue exposed to radio frequency (RF) electromagnetic field (EMF) radiation generated as a result of radio transmissions generated by a UE. The network node generates content for a message for transmission to the UE including the determined one or more SAR-related parameters to be applied by a transmitter in the UE. Based on those one or more SAR-related parameters, the UE determines and implements an action in order to meet the SAR target. Other example embodiments permit the UE to determine the SAR-related parameters in other ways.
