Abstract: Methods and apparatus in a receiver for estimating a received power of at least one signal having a pattern known to the receiver, the signal having being transmitted by at least one antenna. A method includes using a first method of measuring the received power based on the pattern, the first method generating a first sequence of first power estimates; determining whether a predetermined first event has occurred; and if the first event has occurred, changing to a second method of measuring the received power, the second method being different from the first method and generating a second sequence of second power estimates.

Abstract: Methods and apparatus herein facilitate accurate estimation of a mobile terminal's location via location fingerprinting. Specifically, the methods and apparatus obtain a radio fingerprint of the mobile terminal's location based on signal measurements (e.g., signal strength, signal quality, or path loss) performed at a radio frequency distinct from that used to obtain the reference radio fingerprints. The methods and apparatus transform the radio fingerprint, or the reference radio fingerprints, or both, based on that distinction, such as by offsetting signal measurements of the radio fingerprint by an amount determined based on theoretical or experimental models of the dependency of the signal measurements on the radio frequency at which they are performed. The radio fingerprint of the mobile terminal's location may then be compared to the reference radio fingerprints, to accurately estimate the mobile terminal's location despite the radio fingerprint and the reference radio fingerprints having been obtained using different frequencies.

Abstract: The present invention relates to apparatus and methods for communicating on two or more services or transport channels by a multi-branch receiver and for dynamically reconfiguring the multi-branch receiver. The dynamic reconfiguration of the multi-branch receiver may be based on at least one of the measured radio conditions, measured quality of the services, and network-controlled quality of service targets. For each of the services or transport channels, a measured quality target is derived from the network-controlled quality of service targets. Based on the largest of the measured quality targets, one or more of the branches of the receiver is dynamically switched on or off.

Abstract: The invention relates to methods and arrangements for the reliability handling of idle gap commands received in a unit of a mobile telecommunication system. A user equipment located in a cell of a mobile telecommunication network receives signaling gap commands used to activate or deactivate idle gaps for downlink measurements in the neighbor cells. It is determined whether the received gap command is reliable or not. Downlink measurements are then performed in accordance with a predefined rule in case the received gap command is determined as unreliable.

Abstract: A relay node (800) reports its output power capability to a donor base station or other network node separately for the relay node's backhaul and access links, which may have different maximum output power. A corresponding network node (900), such as a donor base station, an Operations & Maintenance node, an Operational Support Systems node, a Self-Organizing Network node, is configured to request the relay node (800) to report its backhaul link and access link output power class capabilities or maximum output powers or rated output powers to the network node (900), and then to receive the reported capabilities in response. The report may specify a per-antenna transmit power capability; this may be specifically requested in some cases. The received relay node power-class capability information for the backhaul and access links is then used for one or several network management functions, such as radio resources management or network planning and dimensioning.

Abstract: A base station is configured to serve a wireless device in a serving cell on a serving frequency. The base station obtains information that indicates one or more non-serving frequencies on which the device is to perform one or more positioning measurements. These positioning measurements are to be used for determining the device's geographic position. For at least one non-serving frequency indicated by the information, the base station configures a measurement gap during which the device is to perform a corresponding positioning measurement. Specifically, the base station configures such measurement gap to occur during a period of time in which a neighboring cell transmits a positioning reference signal over that non-serving frequency. A positioning reference signal is specifically designed to be a signal on which a device performs positioning measurements. Thus, by aligning the measurement gap with a positioning reference signal, the positioning measurements will prove more reliable and accurate.

Abstract: Embodiments herein include a method and a network node in a wireless communications network for controlling a maximum output power of the network node. The network node comprises a Global Navigation Satellite System (GNSS) receiver. The GNSS receiver receives signals from the GNSS. The method comprises determining whether a GNSS signal transmitted from the GNSS is considered detectable. If the GNSS signal is considered detectable, the method includes determining whether the GNSS signal is received directly from the GNSS or via a GNSS repeater. The method further includes selecting a power control method for controlling the maximum output power of the network node, based on at least one of the determination of whether the GNSS signal is considered detectable, and the determination of whether the GNSS signal is received directly from the GNSS or via the GNSS repeater.

Abstract: Methods and arrangements for improving the selection of neighbor cells, on which to perform measurements in different situations. The method in a first node involves obtaining information identifying a first and a second set of neighboring cells for a respective first and second measurement category. A third set of neighboring cells is then determined based on at least parts of the obtained information related to the first and second set. Measurements are then performed in a third measurement category on at least part of the cells in the third set of neighboring cells. The methods and arrangements enable combination of information on neighbor cells, obtained in different ways for different measurement categories into a combined set of neighbor cells, which is more suitable for measurements in a certain measurement category than a set of cells previously obtained for performing measurements in said measurement category.

Abstract: In one aspect, a method and apparatus derive channel quality estimates for given subcarriers in an OFDM signal, based on reference signal (RS) or other known-signal measurements made for another set of subcarriers. In at least one embodiment, a wireless communication apparatus implements a method whereby it is configured for receiving reference information on the first set of subcarriers; generating the first channel quality estimates in the frequency domain, based on the received reference information; computing a power delay profile for the first set of subcarriers; and determining the second channel quality estimates either by extrapolating from the first channel quality estimates or as an average of the first channel quality estimates, depending on a delay spread of the power delay profile.
