摘要： The invention involves management of communication resources (40, 45) in a network (1) utilizing multi-node-adapted resources (40) for transmission of multi-node-associated information and single-node-adapted resources (45) for transmission of single-node-associated information. A default resource allocation (60) specifying, for all transmitter nodes (10, 15) in the network (1), when the respective resource type is available for usage is defined. A subset (10) of the nodes in the network (1) estimates an expected amount of multi and/or single-node-associated information to be transmitted by the node subset (10). The default resource allocation (60) is then dynamically adjusted, for the node subset (10), based on the estimated expected information amount, implying that the physical resources (40, 45) defined by the default time structure (60) are dynamically shared in the frequency domain. According to the adjusted default resource allocation (65), a multi/single-node-adapted resource (40) will be allocated for transmission, by the node subset (10), of single/multi-node-associated information.

摘要： The present invention relates to a method, user equipment and a base station adapted to handle channel state feedback reports in a more flexible way. More specifically, a channel state feedback procedure is provided which utilizes the resources available for transmission of channel state feedback more efficiently. This is achieved by including uplink grant availability into the channel state feedback reporting triggers used for determining when and how to send channel state feedback from a UE, i.e. a channel state feedback reporting request may be sent by a base station in an uplink grant to a UE comprising an indication of an expected amount of information to be returned.

摘要： The present invention relates to a method for reducing inter-cell interference in a cellular radio system in which said scheduler controls a set of shared radio resources. The method comprises the steps of—assigning cell specific resource priority weights (RPW) to the different radio resources of a cell, said assignment differs from the assignment of the same radio resources in at least one neighboring cell utilizing the resource priority weights for selection of radio resources. The resource priority weights can furthermore be combined with channel quality indication reports (CQI) to form weighted quality indexes (WCQI) for the radio resources that are available to the scheduler. The invention also relates to a scheduler performing said method and a radio network node comprising such scheduler.

摘要： A method and arrangement in a communication system for dynamically allocating communication system frequency spectrum after cross-talk interference between transmission medias used for upstream and downstream communication in the frequency spectrum. After detecting cross-talk interference on a disturbed transmission medium caused by transmission on a disturbing transmission of medium, the arrangement transmits a media control signal on the disturbed transmission medium and detects a reproduced media control signal that is reproduced due to cross-talk on the disturbing transmission medium. The disturbed or disturbing transmission media can then be dynamically allocated different frequency spectrum to eliminate the interference. In one embodiment, each transmission medium has a default transmission direction, and if one of the transmissions is in a direction opposite the default direction, that transmission is reassigned to another transmission medium.

摘要： A technique for operating a network node in a heterogeneously deployed network comprising network nodes of different nominal transmit powers and at least partially overlapping coverage areas is described. A method implementation of this technique comprises a step of operating the network node in a base mode in which the network node is configured to transmit terminal-specific demodulation reference signals for a first set of terminal devices. The method comprises the further step of selectively activating or deactivating operation of the network node in a Single Frequency Network (SFN) mode in which the network node is configured to transmit, for a second set of terminal devices, the same cell-specific reference nodes as another network node of the heterogeneously deployed network that has a larger nominal transmit power.

摘要： A base station transmits signals on a frequency (f1) in an active transmission interval (TI) having a starting time and being part of a transmission cycle (TC) including other active transmission intervals for other frequencies (f0, f1, f2, f3) appearing in a predetermined discontinuous transmission scheme that specifies the relationship (Δ1, Az, A3) between the starting times of the active transmission intervals of the frequencies of the set. The mobile station scans the set of frequencies during a scanning cycle (SC) corresponding to the transmission cycle (TC) and determines the frequencies at which the base stations transmit. The start of each scanning is made at a point in time that is specified for the corresponding frequency by the discontinuous transmission scheme and the scanning of one frequency involves ending scanning of this frequency at the end of a time range (TR) of pre-determined length if no signal is detected within this time range.
