  • Publication number: 20220376828
    Abstract: The present disclosure relates to a node (AP2, U11) in a wireless communication system (1), where the node (AP2, U11) is adapted to communicate with at least two other nodes (AP1, AP0) in the wireless communication system (1), and where the other nodes (AP1, AP0) are first type nodes (AP1, AP0) which are adapted to communicate with each other by means of backhaul communication. The node (AP2, U11) is adapted to receive a signal (xA) transmitted from an adjacent first type node (AP1), where the (xA) has been forwarded from at least one farther first type node (AP0). In case of unsuccessful decoding of the signal (xA), the node (AP2, U11) is adapted to request re-transmission (NACK) of the signal (xA), and to receive a re-transmission of the signal (xA) directly from a farther first type node (AP0).

  • Patent number: 11394487
    Abstract: An adaptive receiver system for UEs using NOMA. For example, a network node (e.g, an access point, such as a base station) obtains a first set of data points for a first decoding scheme, each data point included in the first set of data points identifying a maximum achievable rate for the first UE and a maximum achievable rate for the second UE. The network node uses the first set of data points, a first rate demand for a first UE, and a second rate demand for a second UE to determine a decoding scheme for decoding a message transmitted by one of the first UE and a transmission point of the network node.

  • Patent number: 11259254
    Abstract: A variable-length coding method to improve the performance of downlink NOMA. Depending on the channel conditions and the amount of data waiting to be transmitted the UEs served by the NN, the NN groups UEs (e.g., pairs two UEs) with appropriate channel qualities and adapts the transmission powers in different sub-codewords as well as the codeword length such that the UEs minimum quality-of-service requirements are satisfied. This makes it possible to improve the UEs/network achievable rates and the NN energy efficiency.
