摘要： Disclosed is a network node and a method performed by a network node in a wireless communication network for determining signal to noise ratio of a signal received at a receiver from a first mobile station, which signal may include both noise and interference. The method comprises obtaining a plurality of measured noise and interference power values, IN values, of signals received at the receiver in one or more frequency sub-bands, determining IN for a lowest X percentile of the measured IN values, and applying the determined IN for the lowest X percentile as a measure of the noise. The method further comprises obtaining a measured signal strength value for a signal received at the receiver from the first mobile station, and determining SNR for the signal from the first mobile station by applying the determined noise measure.

摘要： A method and a first network node (800) serving a first cell (800A) in a wireless network, for enabling reduction of interference in a second cell (800B) caused by transmission of reference signals in the first cell (800A). The first network node (800) transmits (8:1) scheduling blocks with said reference signals, using a time offset relative transmission of scheduling blocks in the second cell. A timing advance value is determined (8:3) for a wireless device (802) and the wireless device (802) instructed (8:4) to apply said timing advance value for uplink transmissions. The timing advance value was determined such that uplink symbols transmitted from the wireless device (802) are aligned with uplink symbols received at a second network node (804) of the second cell (804A).

摘要： Computer implemented methods for training a Student Neural Network, SNN, and for managing an environment of a communication network using a trained SNN are disclosed. The SNN is for generating an action prediction matrix for an environment in a communication network, the action prediction matrix comprising action predictions for a plurality of nodes or resources in the environment. The training method comprises using a Reinforcement Learning process to train a Teacher Neural Network, TNN, to generate an action prediction for a resource or node in the environment, and using the trained TNN to generate a first training data set including action predictions for individual nodes or resources. The training method further comprises generating a second training data set from the first training data set such that the second training data set includes action prediction matrices, and using the second training data set to update values of the parameters of the SNN.

摘要： Methods and apparatus for uplink power control in a communication system with a low power cell neighboring a macro cell. The low power cell includes a low power node serving a user equipment (UE). The macro cell includes a base station serving one or more other UE(s). The low power node is configured to determine a power offset between the macro cell and the low power cell. The received power spectral density target for the UE calculation is based on the minimum of a first signal strength target for the UE and estimated noise and interference power(s), or a second signal strength target for the UE and the calculated power offset. The uplink power control for the UE is adjusted based on the calculated received power spectral density target. The first signal strength target may be based on the signal-to-interference-plus-noise ratio target for the UE and the second signal strength target may be based on a signal strength derived from a signal-to-noise ratio target for the UE.

摘要： A method performed by radio network node for enabling channel handling of a channel between a wireless device and the radio network node in a wireless communication network. The channel is defined in continuous time and a sampling rate of the channel is non-uniform. The radio network node predicts a channel gain using a first sampling descriptor indicating a first momentary sampling frequency and a second sampling descriptor indicating a second momentary sampling frequency, wherein the first sampling descriptor operates on a different segment of continuous time than the second sampling descriptor. The predicted channel gain enables channel handling such as channel estimation and link adaptation.
