  • Publication number: 20240236713
    Abstract: An improved NR-U framework allows a gNB to repeat RLM-RS with the same index over each sub-band of an unlicensed spectrum. For example, a RLM-RS with the same indices are repeated by the gNB over the sub-bands of a wideband channel in an unlicensed spectrum. By monitoring the different sub-bands, a UE may find one or more sub-bands in which the RLM-RS having a particular index is successfully transmitted at a subsequent time.

  • Publication number: 20240187284
    Abstract: Apparatuses and methods in a communication system are disclosed. A channel predictor is determined to be used in a connection between a base station and a terminal device. The predictor is trained using channel state information of the connection and a predictor function determined to be used both in the base station and terminal device. The base station calculates a predicted state of the channel utilising the predictor function and transmits payload data to the terminal device. The base station receives update information to the predicted state of the channel from the terminal device, where the update information is the variation between the channel predicted at the terminal device and the measured channel.
