Introduced here are visibility platforms able to process the traffic handled by the gateways of an Evolved Packet Core (EPC) with Control and User Plane Separation (CUPS). A visibility platform can include a control processing node (CPN) and one or more user processing nodes (UPNs). The visibility platform may populate a data structure in which the CPN and UPNs are associated with locations along an interface on which Sx/N4 traffic is exchanged between the control and user planes. Each location may be representative of the point on the Sx/N4 interface at which Sx/N4 traffic processed by the corresponding node is acquired. The CPN can use the data structure to program session flows that impact how user traffic is handled by the UPNs.

Systems and methods for PDCCH monitoring in NR systems. The UE provides to a serving cell UE capability information indicating a capability of the UE to monitor PDCCH. The UE capability information indicates a carrier aggregation capability larger than multiple serving cells and has a maximum number indication for a maximum number of PDCCH candidates that the UE can monitor per span. The serving cell transmits an RRC message to a UE in response to the UE capacity information. The RRC message has a per-slot and/or per-span indication to monitor PDCCHs on the serving cell for a maximum number of PDCCH candidates and non-overlapping CCEs. The UE monitors PDCCH candidates and, in the event that a span contains larger than a maximum number of PDCCH candidates or non-overlapping CCEs across multiple served cells, determines whether to monitor a particular PDCCH candidate in the span.

A communication system that includes neural network system configured to learn from training examples of radio frequency (RF) signals, and circuitry configured to label a first set of fifth generation (5G) RF signals originated from a first type of source and a second set of 5G RF signals originated from a second type of source. At least one RF impairment is added randomly to each labelled example of the first set of 5G RF signals and the second set of 5G RF signals, wherein randomization of artificially added RF impairment to each labeled example corresponds to addition of different RF impairments randomly to different labeled examples. The neural network system is trained with a plurality of labelled examples. Each labelled example includes an artificially added RF impairment. The circuitry uses the trained neural network system to detect an input 5G RF signal having a new RF impairment.

Certain aspects of the present disclosure provide techniques for group semi-persistent scheduling (SPS) for path diversity. A method that may be performed by a node includes configuring one or more groups of user equipments (UEs) with one or more SPS resources. The node sends a downlink control information (DCI) to activate one of the SPS resources for one of the groups of UEs and transmits data to the group of UEs using the activated SPS resource. A first UE may receive data from the node using the activated SPS resource and retransmit the data to the second UE. The first helping UE and the second targeted UE may be identified based on the higher layer configuration with the SPS resources, based on information in the DCI, and/or based on information sent with the data.

Systems, apparatuses, and methods are described for presence detection of a wireless device in a sensing region. Communication parameters determined by a computing device over one or more periods may be used to generate criteria for determining the occurrence of enter events or leave events. The criteria may comprise, for values of one or more communication parameters, rates of change associated with movement into or out of the sensing region. The criteria may be compared against subsequent data associated with the communication parameters to determine if an enter event or a leave event has occurred.

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive control signaling comprising an indication of a format for a channel state information report indicating channel state information for a sidelink channel between the first UE and a second UE. The first UE may determine the channel state information for the sidelink channel between the first UE and the second UE. The first UE may configure a layer one uplink control message to indicate the channel state information report according to the format. The first UE may transmit, based at least in part on the format, the layer one uplink control message to a base station indicating the channel state information report.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may belong to a group of UEs and may identify a channel sensing schedule for the group of UEs. The channel sensing schedule may include sensing windows and resource reservation windows corresponding to each UE of the group of UEs. The channel sensing schedule may establish a pattern for the sensing windows and resource reservation windows such that the UEs may take turns performing sensing and resource selection. During a sensing window associated with the UE, the UE may sense a set of resources of a sidelink communication link to identify candidate resources. The UE may transmit, to the other UEs of the group, a message indicating results of the sensing, such as an indication of resource reservations, candidate resources, or the like. The other UEs may identify and select candidate resources based on the message.
