    Abstract: The present invention relates to cellular system and especially to handover between cells on different frequency carriers in an OFDM system or between cells in 2 systems adopting different radio access technologies (RAT), at least one of them being OFDM technology. A problem is the intra-cell interference impact on the quality a connected mode terminal measures in the own cell and in neighbor cells. This is a problem for cells based on OFDM technology, because intra-cell interference has no impact as compared to the inter-cell interference on the quality provided by the cell to a connected mode terminal, whereas in UTRA the intra-cell and inter-cell interference have the same impact on the quality provided. The solution to the problem is based on the insight that for cells that are located on the same site, the eNode B possess information on the power transmitted on the respective frequency carrier, and can adjust the quality as reported from the terminal on co-located OFDM cells. The adjusted quality measure enables an improved evaluation of the quality of co-located cells, for a potential handover. The invention also relates to embodiments on a 2-step handover, wherein handover to inter-frequency, or inter-RAT cell on another site is made as a handover to co-located inter-frequency/inter-RAT cell and a handover to an intra-frequency cell located at the other site.

    Abstract: The invention provides a method and a network node for controlling configuration of measurements to be performed by a user equipment (150a, 150b) operating in a wireless communication system (101). A configured measurement corresponds to at least one reporting criteria and the user equipment (150a, 150b) is able to support a limited number of parallel reporting criteria. Measurements to be performed by the user equipment in parallel may be requested by different network nodes such as a positioning server (140) and an eNodeB (110a, 110b). By letting a network node, such as the positioning server (140) or the (eNodeB 110a, 110b), obtain information on measurements requested by another network node the network node is able to configure the user equipment with a set of measurements that does not exceed at least one predetermined threshold for parallel reporting criteria

    Abstract: A radio network resource controller directs a first network node associated with a first cell region, or a wireless terminal in communication through the first cell region, to measure and report radio resource-related data selected from the group consisting of: resource activity per channel; the number of transmitted power samples that exceed a threshold over a measurement period; and, channel quality samples that exceed a quality threshold. The controller then receives at least one measurement report of the radio resource-related data and, as a function of the radio resource-related data in the first cell region, dynamically reallocates the distribution of resources, such as radio-frequency channels, between the first cell region and at least a second cell region. The invention has a particular advantage in TDD mode of operation where efficient and dynamic interference mitigation is needed to combat the inherent mobile-to-mobile and base station-to-base station interference.

    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: 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.
