  • Patent number: 11973708
    Abstract: Methods and systems for reporting CSI and selecting optimal beams using ML. The CSI report is sent to a gNB, which includes feedback parameters, computed and predicted using ML. The feedback parameters are computed using measurements performed using CSI-RS. Values of the feedback parameters likely at future, based on channel variation and the measurements, are pre-dieted using ML. The computed and predicted feedback parameters are included in the CSI report. Optimal CSI-RS resource allocation and optimal CSI reporting periodicity are determined using ML and sent to the gNB. The CSI report is encoded using the ML based model. The RSRP of the beams are predicted using ML for beam selection.

  • Publication number: 20210204351
    Abstract: A method, mobile device (101) and radio access network RAN (102) are disclosed for suspending and re-establishing a radio resource control (RRC) connection. In some examples, the mobile device (101) indicates a preference to have the RRC connection either suspended or released. In other examples, RAN (102) sends to the mobile device (101) a connection suspend command message instructing the mobile device to suspend a RRC connection with the RAN (102). The mobile device (101), in response to the connection suspend command message, suspends the RRC connection. When the RRC connection is suspended the mobile device (101) cannot transmit or receive user plane data to the RAN (102) and performs functions the same as or similar to idle mode functions. On suspension, RRC connection information is stored and can be used to re-establish the suspended RRC connection.

  • Patent number: 10203882
    Abstract: Embodiments herein provide a method for managing multiple bandwidth boost solutions co-existing in an electronic device. The method includes identifying an ongoing data session associated with at least one of a first bandwidth boost solution and a second bandwidth boost solution. The method includes dynamically selecting at least one bandwidth boost solution based on at least one parameter. The method includes managing multiple bandwidth boost solutions, wherein the bandwidth boost solution can be either network dependent or independent bandwidth boost solution. The method includes determining that the identified event corresponds to a particular bandwidth boost solution or a combination of bandwidth boost solutions. The method includes dynamically selecting another bandwidth boost solution or a combination of bandwidth boost solutions upon determining that the identified event corresponds to a particular bandwidth boost solution or a combination of bandwidth boost solutions.
