The described technology is generally directed towards citizens' broadband radio service (CBRS) channel selection for cellular communication networks in a manner that reduces the risk of CBRS channel revocation due to incumbent activity within a dynamic protection area. A data store can be maintained that includes dynamic protection area location information as well as historic incumbent CBRS channel use information. When selecting a CBRS channel for a radio access network (RAN) node, the position of the RAN node can be considered to determine if the RAN node is in or near a dynamic protection area.

ADJUSTMENT OF DOWNLINK RADIO-FRAME TIMING FOR COORDINATED MULTI-POINT RECEPTION BY USER EQUIPMENT IN ADVANCED COMMUNICATION NETWORKS
The technology described herein is directed towards aligning the downlink symbol timing boundaries of coordinated multi-point (CoMP) transmitting radio units, so that a user equipment receives transmitted signals from each cell at generally the same time. In a CoMP scenario, synchronized downlink transmissions from a connected cell and a cooperating cell are generally not received at the same time by a target user equipment because of different propagation distances from the transmitting radio units; such misalignment leads to performance degradation. By offsetting the downlink symbol timing boundaries relative to each other, a targeted user equipment receives symbols at the desired time boundary, resulting in constructive interference that improves and a cell's downlink throughput and/or coverage. Time alignment via offset symbol timing boundaries also eliminates inter-symbol interference. Modified scheduling can be used to ensure that downlink and uplink transmissions from the coordinated radio units do not interfere with one another.
A system can configure a first number of demodulation reference signal (DMRS) positions in radio resource control information as part of a connection setup with a user equipment that is configured to facilitate broadband cellular communications, wherein the broadband cellular communications are facilitated with carrier aggregation of a primary cell and a secondary cell.

The system can send a second message to the user equipment indicative of modifying the DMRS positions for second communications via the secondary cell. The system can conduct the broadband cellular communications with the user equipment according to the second number of DMRS positions.
The technology described herein is directed towards supporting remote management of machine learning models hosted by network functions in advanced communication networks. Remote management can include model training on more powerful remote machines, along with model selection based on target performance data. A model host (a network function) sends capability data comprising metadata of a local machine learning model to an operator, followed by remote configuration by the operator to enhance the inference accuracy and speed at the network function hosting the model. A model host can retrain a model based on local data, and request remote training if the retrained model does not meet performance criteria. Alternatively, a model host can select a model from a group of models, and request a new model if no selected model of the group meets performance criteria.

An application running on a user equipment determines a retransmission request indication for a packet that was not successfully decoded based on a criticality, or quality-of-service requirement, from a retransmission request configuration, which may correspond to a traffic flow managed by the user equipment. The retransmission request indication may correspond to a criteria range in a retransmission request configuration. The application at the user equipment may determine a latency criteria range to use to determine a retransmission request indication based on a sensed degradation of user experience corresponding to the traffic flow. The user equipment may transmit the retransmission request indication to a network node, which may prioritize scheduling of retransmission of the failed-decoding packet or transmission of new packets according to a priority indicated in the retransmission request indication. A combination of retransmission request indications may be indicated by a compression index determined by the user equipment.
A radio access network node determines a change in condition of traffic directed to a user equipment. The condition change may comprise jitter caused by a core network component or the condition change may comprise lack of traffic to transmit to the user equipment. The node may determine an offset to compensate for the jitter and transmit the offset to the user equipment, to be used by the user equipment to modify previously-scheduled semipersistent scheduling occasions. The node transmits the jitter-altered downlink traffic according to semipersistent scheduling occasions that have been modified by the offset. If no traffic data is present at the node to transmit to the user equipment, the node may transmit an activate/ deactivate indication to be used by the user equipment to deactivate monitoring of a previously-scheduled semipersistent scheduling occasion or to activate monitoring of a different occasion resource.

An error correction component and ΔΤΘM compensation function determine correction factors from a feedback signal to use by digital predistortion to cancel distortion caused by a power amplifier and also determine correction factors that may be used to determine Time of Arrival of an isolation leakage signal. Correction factors may be stored in, or retrieved from, multiple ΔΤΘM functions, which may be part of an ASIC along with the error correction component. The isolation leakage signal may be canceled within the error correction component, resulting in a leakage residual signal that may facilitate determining the ToA of the leakage signal. Cancelling the isolation leakage signal facilitates better sensitivity in detecting the presence of, or ToA of, other signals present at the same port of a circulator from which the isolation leakage signal flows to the error correction component.
