Abstract: The object of the present invention is to reduce interference and power consumption of a repeater operated in a wireless communication network. According to the present invention this object is achieved by a self-optimizing repeater (10) for use in a wireless communication network using predetermined carrier communication resources per cell. The self-optimizing repeater (10) comprises an amplifier (12) adapted to amplify a first subset of communication resources selected from, the carrier communication resources, a monitoring unit (14) adapted to monitor traffic load on the first subset of communication resources, and an adjustment unit (16) adapted to adjust the first subset of communication resources as a function of the monitored traffic load. The operation of the self-optimizing repeater is fully transparent and no control signaling is necessary to control the self-optimizing repeater.

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 associated with uplink and downlink communications, between the first cell region and at least a second cell region.

Abstract: The present invention relates to anode (1) in a wireless communication system, the node (1) comprising at least a first, a second and a third antenna function (2, 2?; 3, 3?; 4, 4?). A first and second downlink signal (Tx1, Tx2), and a first and second uplink signal (Rx1, Rx2) are transferred via said antenna functions (2, 3, 4; 2?, 3?, 4?), which together form a first total antenna function (A1, A1?) and a second total antenna function (A2, A2?). The first and second downlink signals (Tx1, Tx2) are transferred via the first total antenna function (A1, A1?), and the first and second uplink signal (Rx1, Rx2) are transferred via the second total antenna function (A2, A2?). The second downlink signal (Tx2) and the second uplink signal (Rx2) are transferred via a common connection (5, 5?) connected to a filter means (6, 6?) which is arranged for separating these signals (Tx2, Rx2) to connect them to different antenna functions. The present invention also relates to a corresponding method.

Abstract: The present invention relates to methods and arrangements in a wireless communication system that enable the allocation of resources to UEs based on measurements of their antenna polarization, in order to suppress the interference between different UEs at a very low overhead cost. This is achieved by a solution where the scheduling unit retrieves information about the polarization of the UE antenna configurations, and based on this information allocates radio resources to the different UEs, with the aim to minimize the interference. The scheduling unit may retrieve the information from the RBSs or from the UEs. The RBS and the UE will determine the polarization and transmit information regarding this polarization to the scheduling unit. The scheduling unit coordinates the allocation of resources with other scheduling units if necessary.

Abstract: According to teachings presented in this document, reported channel quality information, as used for controlling one or more aspects of wireless transmission, is compensated according to an aging function that depends on channel variability. In this manner, the “amount” or extent of age-based compensation applied to the channel quality feedback for a given user—e.g., a mobile station or other item of user equipment—varies as function of that user's channel conditions. More particularly, in an advantageous approach, the aging function applied to the channel quality estimates received from a given user depends on estimates of that user's channel variability. Channel quality estimates from (or generated for) a user whose channel conditions are changing very little, or at least are changing very slowly, may be aged less aggressively than those associated with a user whose channel conditions are changing more rapidly.

A base station and a computer readable medium is also described.

Abstract: An object of the present invention is to provide a mechanism for controlling a repeater that is less costly and more flexible. The objective is achieved by a method in a control unit (150) for controlling a repeater (100) being comprised in a radio access network (110). The control unit sends a repeater control message to the repeater (100). The repeater control message is tunneled as ordinary data communication via an available radio communication channel (160) within the radio access network (110). The repeater control message is configured to control the repeater (100).

Abstract: According to embodiment of the present invention, there is provided a radio base station (20) and a corresponding method for estimating the quality of the uplink control channel. The method comprises measuring (32, 42) a quality parameter of the uplink data channel, and using (38, 50) this to estimate the quality of the uplink control channel. In one embodiment, measurements of the uplink control channel are taken and their reliability determined. If the reliability is low (i.e. below a threshold, or below the respective measurements taken on the uplink data channel), then measurements on the data channel are used instead of those made on the control channel to estimate the control channel quality.

Abstract: The present invention provides a method and a radio base station (4) which actively monitor the error rate for messages transmitted over an uplink control channel between the radio base station (4) and one or more mobile terminals (6). The distribution of messages transmitted on the uplink control channel is then adapted in dependence on the measured error rate.

The second device (122) receives the classification of the data, receives information associated with a resource (460), calculates an expected interference associated with the resource (460) based on the information associated with the resource (460), and allocates, to the resource (460), data classified as a control message when the expected interference corresponds to a low expected interference.

Abstract: For uplink cooperation of a serving access node (100-1) one or more supporting access nodes (100-2) are selected. The selection is based on a characteristic of a link between a terminal (200) served by the serving access node (100-1) and the supporting access node (100-2), or is based on a characteristic of a link between a further terminal (200?) served by the supporting access node (100-2) and the serving access node (100-1). The characteristics of the links may comprise a signal quality, e.g. a path gain, a signal strength, or a latency. The characteristics of the links may also comprise scheduling information, e.g. time resources and/or frequency resources used on the link.

The present invention also relates to a corresponding wireless communication system and corresponding antenna functions.

In response to a transmitter power change request from a mobile terminal (110) over a wireless connection, a base station (122) determines a power control parameter based on its current total transmitter power PDL. The power control parameter preferably relates to a maximum connection-specific transmitter power, a power step size and/or a power increase probability, and is used by the base station to distribute transmitter power pi to the connection.
