Abstract: The present invention relates to methods and devices for mobility management UE in a cellular communications system. A user equipment maintains (21) at least two sets of mobility trigger parameters. Each set of mobility trigger parameters corresponds to a predetermined user equipment speed range. The user equipment determines (22) a speed range that the speed of the user equipment falls into and selects (23), based on the determined speed range, at least one set of mobility trigger parameters to be used for performing mobility-based decisions. If the user equipment is in connected mode a network base station may select a set of mobility trigger parameters to be used for performing handover decisions based on a determined speed range of the user equipment. Advantages are that ping-pong mobility decisions may be avoided and it is sufficient to determine a range for the UE speed, which is less complicated than determining an accurate speed of the UE particularly in idle mode.

Abstract: In a User Equipment, frequency search is performed using the physical location (e.g. GPS position) and using information about the allocation of frequency bands and the radio access technologies used in these bands in different regions or countries. Hereby, frequency searching can be reduced to those bands and to the corresponding radio access technologies which are used in a current physical location. In order to ensure that UE is configured with the latest and most relevant regional frequency information, regional frequency information is transmitted to the UE over the air interface. In addition, information related to user's travel itinerary and user's travel history can be taken into account. By only frequency searching relevant frequency bands for the radio access technologies used in these bands battery power consumption can be reduced and frequency search speed can be improved.

Abstract translation: 在用户设备中，使用物理位置（例如，GPS位置）进行频率搜索，并且使用关于频带分配的信息以及在这些频带中在不同地区或国家中使用的无线电接入技术。 因此，可以将频率搜索减少到在当前物理位置中使用的那些频带和相应的无线电接入技术。 为了确保UE配置有最新和最相关的区域频率信息，区域频率信息通过空中接口传送给UE。 此外，可以考虑与用户旅行行程和用户旅行历史有关的信息。 通过仅对这些频带中使用的无线电接入技术的相关频带进行频率搜索，可以降低电池功率消耗并且可以提高频率搜索速度。

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.

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.

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.
