摘要： 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 5 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.

摘要： Methods and devices are provided whereby scrambling codes can be set in an improved way. In accordance with one embodiment a method is provided in a User Equipment for generating a second scrambling code or a second scrambling code group. The UE is configured for multi carrier operation receiving downlink transmission from a Universal Mobile Telecommunications System Terrestrial Radio Access Network on a set of at least two downlink carriers including an anchor carrier and at least a first secondary carrier. The method comprises determining a first scrambling code or a first scrambling code group associated with a first cell on the anchor carrier; and deriving a second scrambling code or a second scrambling code group associated with a second cell on said first secondary carrier using a predefined rule defining the relation between the second scrambling code or second scrambling code group and the first scrambling code or scrambling code group. Hereby interference suppression / cancellation processing is enabled in a receiver of a UE on secondary cells in multi-carrier scenarios that do not transmit the SCH, while minimizing the need for overhead in terms of signaling of the scrambling codes for neighbouring cells in a UTRAN system. Methods and devices for E-UTRAN are also described.

摘要： 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.
摘要翻译：在用户设备中，使用物理位置（例如，GPS位置）执行频率搜索，并且使用关于频带分配的信息以及在这些频带中在不同区域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。
