摘要： A network node (200) a wireless device (202) and methods therein, for configuring a wireless link (204) to be used for controlling a process at a wireless device (202) involving communication of control signals and feedback signals over the wireless link (204). The network node (200) sends a request message (2:2) to the wireless device (202) comprising a request for performance requirements of the wireless link (204) needed for the communication of control signals and feedback signals. The wireless device (202) determines (2:3) the performance requirements based on at least one of: 1) characteristics of the process, and 2) requirements for how the process is controlled. The wireless device (202) then sends (2:4) a response message comprising the performance requirements to the network node (200) which configures (2:5) the wireless link (204) so that the performance requirements of the wireless link are fulfilled. The process can thereby be properly controlled by the network node (200) by sending the control signals (2:7a) to the wireless device (202) and receiving the feedback signals (2:7b) from the wireless device (202) over the configured wireless link (204).

摘要： Recovery control is provided for recovering data packet flow control between a network node and a radio base station over a radio network interface. The base station communicates with at least one user equipment, UE, over a radio interface and measures information relating to a data transmission rate over the radio interface and an amount of a downlink packet queue in the base station associated with the UE communication. In one embodiment, the base station sends at least some of the measurement information to the network node. A process controller in the network node processes the measurement information to determine a desired amount to be stored in the downlink packet queue. The process controller determines a commanded bit rate to transmit data from the network node to the downlink packet queue based on the determined desired amount and transmits data to the radio base station in accordance with the commanded bit rate.

摘要： A radio network node serves a first cell in a radio communications network, and is configured to measure a received total power value at the radio network node in the first cell, compute a factor indicating a load in the first cell, estimate a noise floor level in the first cell, and compute a utilization probability value of the load in the first cell and a neighbor cell interference value simultaneously in a non-linear interference model. This is based on the measured received total power value, the computed factor, and the estimated noise floor level in the first cell. The neighbor cell interference value is an interference from at least one second cell affecting said first cell, and the utilization probability value of the load in the first cell and/or the neighbor cell interference value is to be used for managing radio resources in the radio communications network.

摘要： A method for adjusting beam gain in a radio network node. The method comprises: obtaining a channel estimate based on a reference signal transmitted by a target wireless device; applying a set of weights to the channel estimate to obtain a weighted channel estimate; and outputting the weighted channel estimate for use in determining beamforming weights to be applied to signals output to a plurality of antenna elements for transmission to the target wireless device, wherein the beamforming weights are determined as a function of the weighted channel estimate.

摘要： Mechanisms for controlling average Equivalent Isotropic Radiated Power (EIRP) of a radio base station, in which a method is performed by a control device. The method comprises performing control of average EIRP of the radio base station according to a back-off power density control loop. In the back-off power density control loop, a beam width control parameter is used to vary the average EIRP generated by an antenna array of the radio base station, whereby the average EIRP is selectively reduced based on the beam width control parameter.

摘要： A method for wireless backhaul inter-node communication between a first backhaul node and a second backhaul node is provided. The method includes computing a beamforming weight matrix W; and the first backhaul node using the beamforming weight matrix W to transmit and/or receive data to and/or from the second backhaul node. The beamforming matrix W is computed as the inverse of a weighted channel estimate matrix (Formula I), such that W=(Formula II), where Ĥ is a channel estimate matrix and ρ is a weighting factor matrix such that (Formula III) where ρ has dimension Nrx by Ntx, where Nrx is the number of receive antennas and Ntx is the number of transmit antennas, where Ntx,=Nrx, and ρ is a scalar between 0 and 1, and where ∘ denotes a Hadamard matrix product.

摘要： A method (300) for indoor positioning or navigation comprises obtaining (310) a set of features which describe characteristics of a place in an indoor space. This obtained set of features may describe characteristics of a place at which a wireless device is located, a place targeted by a wireless device as a destination, or a place targeted by a wireless device to avoid. Regardless, the method (300) further comprises comparing (320) the obtained set of features to addresses of respective indoor blocks into which the indoor space is spatially divided. Each indoor block in this regard is identified as being located at an address formed from a set of features which describe characteristics of the indoor block. The method (300) also comprises determining (330), based on the comparing, which of the indoor blocks corresponds to the place in the indoor space.

摘要： A method of determining the position of a moving unmanned aerial vehicle (UAV) is provided. The method comprises obtaining, for each of three or more base stations, one or more measurements of a carrier frequency offset (CFO) for one or more signals sent between a moving UAV and the respective base station. The method further comprises inputting the CFO measurements into a model to determine a position of the UAV, in which inputs to the model do not include range measurements of the UAV with respect to the three or more base stations.
