摘要： Methods and arrangements in a telecommunication network for intercell interference coordination. The telecommunication network comprises a first base station, acting as serving base station for a mobile station, and a second base station. The method comprises determining that transmission interference to the mobile station is to be limited. The method also comprises triggering the mobile station to send a signal on a radio resource, which signal is to be received by the second base station, enabling the second base station to select a transmission parameter that limits interference for the mobile station.

摘要： In one embodiment, a method in a network node is provided. The network node is configured to use a first power level for transmitting data in subframes of a first type, and to use a second power level for transmitting data in subframes of a second type. The method comprises signaling (520) first and second information to a network entity. From the first information, a power offset for subframes of the first type is derivable. The first power offset represents a relation between a power level for transmitting reference signals and the first power level. From the second information, a power offset for subframes of the second type is derivable. The second power offset represents a relation between the power level for transmitting reference signals, and the second power level.

摘要： Transmit power control methods and apparatus are disclosed. In several embodiments, a mobile terminal (200) is configured to effectively ignore 'UP' transmit power control commands in the event that the mobile terminal (200) is operating in a power-limited state. In an exemplary method for controlling transmit power at a mobile terminal (200), a plurality of transmit power control commands are received. An accumulated power control value is adjusted (350) in response to each transmit power control command that directs a negative adjustment in transmit power. However, the accumulated power control value is adjusted (350) in response to a transmit power control command that directs a positive adjustment in transmit power only if the mobile terminal (200) is not in a power-limited state. Transmit power settings for each transmission are calculated (360) based on the accumulated power control value and the one or more radio link parameters.

摘要： A method in a first base station for determining a spectrum allocation to be used by the first base station in a wireless network is provided. The wireless network is dedicated a spectrum S. The first base station is associated with a first operator. The first base station detects (403) a number N of second signals. Each second signal is transmitted by a respective second base station to announce its intended use of said spectrum at a time t. Each second base station is associated with a respective second operator or the first operator. The first base station then determines (404) the spectrum allocation to be used by the first base station at the time t as a subset of the spectrum S. The subset of the spectrum S is a function of N.

摘要： The present invention relates to a method for uplink transmission in a cellular telecommunication network supporting both DFT-spread OFDM and regular OFDM as access schemes in the uplink. The method comprising the steps of: receiving a resource allocation message from the network; determining whether said resource allocation fulfills at least one predefined condition that implicitly indicates which access scheme to be used in uplink transmission; if a condition for implicit indication is fulfilled, selecting access scheme according to a pre-defined rule, applying the selected access scheme in the uplink transmission. Hereby, in case of fulfillment of any of the predefined conditions, no explicit signaling of information regarding the usage of DFT-spread OFDM or regular OFDM is required. The invention furthermore relates to a terminal capable of performing said method, a method in a network node, and a network node.
