  • Patent number: 11956031
    Abstract: Communication of Measurement Results in Coordinated Multipoint Methods (200, 400, 600) performed by a wireless device (1100), Radio Access node 5 (1300) and training agent (1500) are disclosed. The wireless device is operable to receive signals over a communication channel from a Transmission Point (TP) of a communication network, which TP is a member of a Coordinated Multipoint (CoMP) set and may be managed by the Radio Access node. The method (200) performed by the wireless device comprises performing a measurement on communication channels to 0 each of a plurality of TPs in the CoMP set (210), and using an autoencoder to compress a vector of measurement results of the performed measurements (220). The method further comprises transmitting the compressed vector of measurement results to TPs in the CoMP set (230) and receiving a joint transmission from TPs in the CoMP set (240).

  • Publication number: 20240095499
    Abstract: Methods and apparatuses for noise learning-based denoising of noisy input data Y that is equal to the original data X plus the noise N (i.e., Y=X+N). In contrast with a conventional denoising autoencoder (DAE) method that attempts to learn the original data X directly from noisy input data Y, the noise learning-based denoising learns the noise N in the noisy input data Y and then regenerates the original data X by subtracting the learned noise N from the noisy input data Y. Learning the noise N may include inputting the noisy input data Y into an encoder of a neural network, and the learned noise N may be output from a decoder of the neural network. Training the neural network may include inputting noisy training data into an encoder of the neural network and outputting training noise from a decoder of the neural network.

  • Publication number: 20230217264
    Abstract: A method for dynamically assigning communication resources between two or more radio access technologies (RAT) in a wireless access network. The method includes obtaining a network observation ot indicating a current state of the wireless access network, predicting a sequence of future states of the wireless access network by iteratively simulating hypothetical communication resource assignments a1, a2, a3 over a time window w starting from the current state, evaluating a reward function for each hypothetical communication resource assignment a1, a2, a3 over the time window w, and dynamically assigning the communication resources based on the simulated hypothetical communication resource assignment a1 associated with maximized reward function over the time window w when the wireless access network is in the current state.

  • Publication number: 20230209586
    Abstract: A computer implemented method performed by a network node in a non-public communication network is provided. The method includes predicting a subsequent position of a first communication device served by a public communication network, wherein the first communication device is causing an interference level on the non-public communication network. The method further includes estimating a level of subsequent interference from the first communication device for the subsequent position. The method further includes initiating control of radio resources to reduce the estimated interference level from the first communication device.

  • Publication number: 20220394736
    Abstract: In a method in a node of a communications network for scheduling enhanced mobile-broadband, eMBB, transmissions, the eMBB coverage area interferes with an ultra-reliable low latency communication network, URLLC. In a first block (302) a time division duplex, TDD, pattern for the URLLC is predicted based on historical URLLC TDD data. In a second block (304) an eMBB TDD pattern is scheduled, based on the predicted URLLC TDD pattern, so as to manage cross-link interference on the URLLC network.
