摘要： A method and an arrangement in a first radio network node for determining a channel quality offset for a radio channel for sending data from the first radio network node to a user equipment are provided. The first radio network node receives from the user equipment channel quality information for the radio channel. The first radio network node estimates resource utilization and signal-to-noise-ratio for the user equipment. The first radio network node determines the channel quality offset based on the received channel quality information, the estimated resource utilization and the estimated signal-to-noise-ratio.

摘要： A method of selecting at least one communication link in a wireless communication network is proposed, comprising the steps of transmitting from at least one transmitting node in the network a pilot signal from each of at least two transmitter antennas of the transmitting node, receiving the pilot signals from the at least two transmitter antennas in a receiving terminal, estimating, in the terminal, a covariance matrix of the channel, based on the pilot signals received, determining the pathloss for each antenna based on the covariance matrix, selecting one of at least two possible links for the communication between the terminal and the transmitting nodes. The terminal is enabled to measure on each transmitter antenna individually, which provides a better tool for link selection and cell selection.

摘要： A method for managing uplink channel estimation in a base station includes transmitting downlink data from a base station to a mobile terminal in a radio access network over a first portion of a Frequency Division Duplex (FDD) spectrum. The first portion of the FDD spectrum is designated for downlink data transfer. The method also includes transmitting a predetermined reference signal from the base station to the mobile terminal over a second portion of the FDD spectrum. The second portion of the FDD spectrum is designated for uplink data transfer. The predetermined reference signal permits the mobile terminal to perform a channel estimate on at least a portion of the second portion of the FDD spectrum. The method additionally includes receiving uplink data transmitted from the mobile terminal to the base station over the second portion of the FDD spectrum.

摘要： The present invention relates to a scheduler selector and a method for improving network quality by controlling intercellular interference of a multi-cellular mobile radio communication network. The radio communication traffic is controlled by a user traffic scheduler principle. The network quality is improved by selecting another scheduling principle among a number of pre-defined and selectable scheduling principles than the scheduling principle working for the moment in a cell in said network. Said selection being initiated as a result of an intracellular Quality data processing wherein the network quality is determined to be possible to improve.

摘要： Available bandwidth is divided into multiple sub-channels, and respective sub-bands containing one or more of these sub-channels are allocated to one or more users. A first frequency allocation is determined, and mathematical operators are used to determine at least one further frequency allocation from the first frequency allocation. A frequency hopping sequence is then determined, including the first frequency allocation, and the or each further frequency allocation. A network node may perform the allocation method, and a user equipment may operate using the allocated bandwidth.

摘要： An estimate of a cost of allocating radio resources available for allocation to the at least one radio link within a cell is generated in dependency 5 of which radio resources have been used within the cell at previous times.

摘要： The object of the present invention is to provide a mechanism for a more efficient carrier search. The object is achieved by a method for sending a signal in a first node. The first node communicates with a second node via radio communication, which radio communication is performed by multi carrier transmission. The first node uses a carrier, being associated with a frequency range. The method comprises the step of transmitting an end-marker signal within or close to the frequency range. The end-marker signal is intended to be received and used by the second node for identifying the frequency range of the used carrier.
