  • Publication number: 20230379779
    Abstract: In a method of operating a Radio Access Network (RAN) to optimize a handover between two gNBs, in addition to exchanging the respective AMF region IDs between the two gNBs, all supported GUAMIs of each gNB shall be exchanged as part of the Xn setup procedure, thereby enabling each gNB to know the supported GUAMIs of the peer gNB. Before initiating the Xn handover, source gNB shall check whether the target gNB supports the AMF which currently serves the UE. If supported, the source gNB shall proceed with the Xn-based handover. If the AMF is not supported by the target gNB, the source gNB shall initiate the NGAP handover. In addition, whenever there is any change in supported GUAMIs (addition/deletion/modification), each gNB shall initiate a New Generation Radio Access Network (NG-RAN) Configuration Update procedure towards the peer gNB with the changed list of GUAMIs.

  • Publication number: 20230078276
    Abstract: A method for channel prediction for uplink (UL) and downlink (DL) massive Multiple Input Multiple Output (MIMO) systems for Open Radio Access Network (0-RAN) fronthaul Split 7.2 networks enables prediction of a channel that is seen by the UL slot. The pre-processing matrix is computed by the distributed unit (DU) based on this predicted channel and sent to the radio unit (RU) for minimizing the effects of channel aging. A channel corresponding to sounding reference signal (SRS) symbol closest to uplink slot being decoded can be predicted from previous SRS symbols and can be used as a combining matrix. Alternatively, the channel of the uplink slot itself can be predicted from past SRS symbols, and a combining matrix can be generated based on the predicted channel.
