摘要： A NodeB (105) for an HSPA enabled WCDMA network (100), arranged (11, 12, 13) to transmit beam forming instructions to a User Equipment, a UE (1 10), which is arranged for beam forming. The beam forming instructions comprise information identifying a code book with one or more code words, and the NodeB is also arranged to transmit code words from said code book to the UE at a certain rate. The NodeB is further arranged to determine said rate based on dynamically varying information available in the WCDMA network, and to receive said information on the code book from an RNC upon configuration of the U E or to choose code book based on said dynamically varying information available in the WCDMA network.

摘要： In a receive node of a wireless network, an iterative multi-user multi-stage interference cancellation receiver is used. After each stage of interference cancellation, interference characteristics change. An adaptive finger placement strategy is used in which after each stage of interference cancellation, finger delays and combining weights of the receiver are adapted to reflect the changed interference characteristics.

摘要： A method for power measurements in a cellular communication system comprises receiving measurement configuration orders. Operation of a power meter is controlled in dependence on the measurement configuration orders. Reference signal received powers are measured. A measurement report is compiled and transmitted. The measurement configuration orders comprise cell status information associated with neighbouring cells and measurement instructions that are dependent of the cell status of respective cell. The cell status information comprises information about whether the neighbouring cell is of a different type than the serving cell. Controlling of the operation of the power meter and/or compiling of the measurement report is performed in dependence on the cell status of the neighbouring cell. A method for handover based on such measurement reports is also disclosed as well as Node Bs and user equipments configured to perform such methods.

摘要： The invention describes a flow control method to control HS-DSCH data streams over UTRAN Iub and Iur interfaces. Two credit assignment schemes are also described. A radio network node at which the flow control method executes is proposed. Finally a computer program product for execution of the flow control method and the credit assignment schemes is described. The control of separate user data flows is coordinated by Node-B and data transport over the Iub and Iur interfaces is adapted to data transfer over the Uu interface. The main advantage is that buffering can be primarily maintained in SRNC. It is shown that the proposed flow control method can significantly reduce Node-B's buffer level when compared to a scheme where the control of individual data flows is performed independently of each other. It is also shown that the negative impact on the quantity of flowing data is generally minor.

摘要： Systems and methods are provided for managing communications between two or more ad-hoc networks in a communication system. The systems and methods may have flexible communication time sharing of one or more nodes taking part in two or more ad-hoc networks. For example, the communication scheduling function for a node shared by two or more ad-hoc networks is provided with a generic functional architecture such that it may be located in a number of different locations. In one embodiment, a Bluetooth communication system includes an inter-piconet scheduling function having a JUMP mode introduced to distinctly identify a node to its neighbors as being shared with multiple ad-hoc networks. The jump mode may have one or more methods for managing the inter-network communications that may include: (1) predetermined fixed starting point and length communication windows, (2) time points with flexible starting points and communication window length, and/or (3) random starting time and length communication windows.

摘要： A first User Equipment (UE), a second UE, a first Radio Network Node (RNN), and methods therein for controlling interference between transmissions in a first system and transmissions in a second system. The first system comprises the first UE and the first RNN serving the first UE. The second system comprises the second UE and a second RNN serving the second UE. The first system has a first priority in a first part of a shared spectrum and the second system has a second priority in the first part of the shared spectrum, wherein the first priority is higher than the second priority. The method in the first UE comprises transmitting a signal to a second RNN that is to perform a downlink transmission to the second UE, which signal is configured to control the transmission of the second RNN.
