摘要： The present invention relates to a method and a user equipment for use in a wireless communication system that allow for improved uplink transmit diversity performance by using downlink measurements for making informed decisions on whether or not to change precoding vector for uplink transmission. The user equipment measures (32) downlink characteristics, such as received power, on a plurality of antennas of the user equipment. Based on the measured downlink characteristics a precoding vector for unlink transmission is determined (38). The determined precoding vector is then used to perform uplink transmission (31).

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： 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： In accordance with the invention, signal information representative of a first set of information to be transmitted more than one time over at least one link is stored as a priori known signal information. This could be previously received and/or, detected information, own transmitted information or otherwise available relevant signal information in the node. Signal information representative of a second set of information is received, wherein a transmission of the first set of information interferes with the reception of the second set of information. In spite of the interference, at least part of the second set of information can still be successfully be detected by exploiting the received signal information and at least part of the previously stored a priori known signal information. The information is detected by interference cancellation based on the received signal information and relevant parts of the a priori known information. The set of priori known signal information is preferably updated by continuously storing newly detected information.

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.
