Abstract: Methods and arrangements (400, 600) in network nodes (101, 102, 110) for controlling radio emission from a mobile terminal (102) are provided. The mobile terminal (102) is located in a critical area. The network node sends a location parameter of the critical area, wherein the location parameter indicates a geographical location of the critical area. The first radio network node (101, 110) sends a first set of control parameters to the mobile terminal. The mobile terminal determines a geographical location of the mobile terminal and controls radio emission from the mobile terminal based on the first set of control parameters, the location parameter and the geographical location of the mobile terminal. Methods and arrangements (900) in a first radio network node (101, 110) for performing admission control are provided. The first radio network node (101, 110) receives a service request. In another step, the first radio network node (101, 110) denies the service request if an aggregated number of mobile terminals attached to the first radio network node (101, 110) exceeds a predetermined mobile terminal number or total received power at the first radio network node exceeds a predetermined threshold.

Abstract: The auto-correlation properties of a reference signal or pilot pattern, such as a position reference signal (PRS) in a Long Term Evolution communication system, is improved by modifying the currently specified PRS patterns, and/or by PRS pattern shaping. Pattern shaping can result in creation of virtual PRS patterns, for example, by controlling the PRS transmitted or received power used by the correlator. PRS power shaping can be implemented differently according to the location where the PRS power is calculated, e.g., in a network node or in a user equipment.

Abstract: A method in a base station for configuring a wireless terminal for performing a cell reselection or handover evaluation process “evaluation process” is provided. The wireless terminal is arranged to perform multiple evaluation processes parallel to each other, which multiple evaluation processes are governed by different set of mobility parameters.

The base station signals (306) an identifier to the wireless terminal (110), which identifier identifies the determined whether or not the multiple parallel evaluation processes shall be configured to be used by the wireless terminal for evaluating cell reselection or handover.

Abstract: In a cellular radio system Transmission Power Control (TPC) power offset is set so that it is adjusted for each transmitting radio base station based on available relevant measurements that reflect the quality of the downlink channel carrying the uplink TPC command whereby an improved performance is obtained. The TPC power offset can for example be based on an estimated uplink Dedicated Physical Control CHannel (DPCCH) SINR, the number of TPC “up” and the number of TPC “down” sent by a radio base station and aggregated UE receiver power or UE transmit power over a number N slots. Also a mobile station used in a cellular radio system supporting soft handover may be adapted to apply TPC discarding thresholds based on the number and the quality of simultaneously received TPC commands. The discarding procedure in the mobile station may also be carried out selectively such that TPC commands that are determined to be unreliable are not discarded but selectively discarded based on how reliable they are determined to be.

Abstract: Mobility parameters, such as those used in handoff decisions, are based on the speed of User Equipment (UE) (10), measured at two points. UE speed estimates are taken at both the UE (10) and base station (12), and the two speeds compared. If the speeds match (or differ by less than a predetermined amount), one or more mobility parameters are adapted based on the UE speed. These parameters may include time to trigger (TTT), time to satisfy (TTS), measurement time, forgetting factor, β, measurement period (Tm), handover prohibit timer, MeasurementReportingmargin, HOmargin, hysteresis, and the like. The UE speed comparison may be performed at the UE (10) or at the base station (12). In one embodiment, a plurality of UE speed ranges are defined (e.g., low, medium, high), with corresponding mobility parameter values associated with each range.

Abstract translation: 移动性参数，如用于切换决策的参数，是基于在两点测量的用户设备（UE）（10）的速度。 在UE（10）和基站（12）两者都进行UE速度估计，并且比较两个速度。 如果速度匹配（或差别小于预定量），则基于UE速度来适配一个或多个移动性参数。 这些参数可以包括触发时间（TTT），满足时间（TTS），测量时间，遗忘因子，测量周期（Tm），切换禁止定时器，测量报告率，停留时间，滞后等。 UE速度比较可以在UE（10）处或在基站（12）处执行。 在一个实施例中，多个UE速度范围被定义（例如，低，中等，高），具有与每个范围相关联的对应的移动性参数值。

Abstract: The technology applies to a cellular radio network where each cell area is associated with a radio base station in which mobile terminals communicate with at least one of the base stations over a radio interface. The mobile terminals perform mobility-related measurements on downlink signals received from a corresponding neighbor cell during time slots configured for downlink transmission measurement. A configuration node receives input information, and based on that received input information, determines measurement time slot configuration information. The node provides the measurement time slot configuration information to the base stations so that the base stations may signal the measurement time slot configuration information to mobile terminals.
