摘要： Embodiments herein relate to a method performed by a network node for determining a precoder for a transmission to a first wireless device in a wireless communications network. The network node obtains at least a Rank Indicator, RI, of the channel used for transmissions to the first wireless device. The network node also obtains information about a preferred interference subspace for the transmissions to the first wireless device from a second wireless device in the wireless communications network, wherein the second wireless device is interfered by the transmissions to the first wireless device. The network node determines the precoder for the transmission to the first wireless device based on the obtained information about a preferred interference subspace if the at least obtained RI of the channel fulfills a first threshold criterion. Embodiments of the network node are also described.

摘要： Determining of transmission properties of a telecommunication transmission line wherein a complex input impedance of the line is first determined (204) from the relationship between a signal sent on the line (200) and a received resulting signal (201). For frequencies for which the absolute value of the propagation constant times line length is less than, the line input impedance can be expressed in terms of line constants (line capacitance, resistance, inductance and conductance) and frequency using a Taylor series expansion. After truncation of higher order terms and insertion of measured values, the resulting system of equations can be solved and the line constants generated (206), provided that there are at least two frequencies. Furthermore, from the line capacitance and a standard value for line capacitance per km, a line length can be estimated (207).

摘要： The length and attenuation of a signal line between a transmitter and a customer premises equipment is to be estimated. A frequency dependent line input impedance (Z in (f)) as seen from the transmitter, is measured and an absolute impedance value (oe Z in (f) oe), is generated. The latter is shown as a curve (A1) in the diagram with the frequency (f) on the abscissa and the impedance (oe Z in (f) oe) on the ordinate. Extreme values (Max. 1 , Max 2 , Max 3 ; Min 1 , Min 2 , Min 3 ) arc denoted and a frequency distance (FD 1 -FD 4 ) between two consecutive of the extreme values is generated. The line length (L) is generated as L=½.vop/FD 1 , in which vop is the velocity of propagation of a signal on the line. The attenuation is estimated by multiplying the line length with an average attenuation value for the actual line type. The advantages are that the line length can be estimated with good accuracy in a simple manner for short lines and that the line attenuation is estimated in a simple manner.

摘要： A method (100) for generating an indication of remaining battery life for a wireless device is disclosed. The wireless device is positioned in an installation location and operable for radio communication with a communication network node. The method comprises estimating a signal loss between the wireless device in the installation location and the communication network node (120) and mapping the estimated signal loss to an indication of remaining battery life for the wireless device (130). The mapping is based on remaining battery capacity for the wireless device and estimated energy consumption of the wireless device for radio communication, the estimated energy consumption being generated from the estimated signal loss and determined communication parameters for the wireless device. Also disclosed are an apparatus (300, 400) for generating an indication of remaining battery life for a wireless device and a computer program product configured to carry out a method for generating an indication of remaining battery life for a wireless device.
