Abstract: Methods and apparatus for controlling monitoring operations performed by various devices, e.g., access points, in a communications network and for using information obtained by the devices which perform the monitoring are described. The methods are well suited for use in a system with a variety of access points, e.g., wireless and/or wired access points, which can be used to obtain access to the Internet or another network.

In response to detecting a communications failure, the access point generates, an event failure notification indicating the type of detected failure and sends the event failure notification to the network monitoring node along with corresponding captured packets.

Abstract: Methods are provided for configuring an initial CORESET and associated search space during beam management. A base station (BS) receives measurements of at least one downlink reference signal (RS) from a User Equipment (UE), wherein each of the at least one downlink RS is associated with a transmit beam. The BS selects, based on the received measurements, a transmit beam for transmitting on resources of an initial time and frequency control resource set (CORESET), wherein the initial CORESET schedules unicast Physical Downlink Data Channel (PDSCH) for the UE, wherein the initial CORESET is identified during initial access of the UE to the BS. The BS transmits information relating to the initial CORESET on the selected beam in a Medium Access Control (MAC) Control Element (MAC-CE), wherein the information is transmitted using a combination of bits in the MAC-CE, the bits configured for indicating CORESETs.

Abstract: A command and control (C2) radio system configured for same-channel out-of-band sensing is disclosed. In embodiments, the radio system (e.g., an air radio system (ARS) aboard an unmanned aircraft system (UAS) or a ground radio station (GRS)) scans its switching back to the appropriate operating frequency before the next subframe starts. The radio system processes the collected energy samples to determine minimum and mean operating frequencies for idle subframes and slots where a preamble is not detected. The radio system uses idle frames to scan sensing frequencies assigned by a central server of the C2 link system, collecting spectral energy sources during the idle timeslots and energy levels, thereby identifying the level of interference on the assigned frequency (e.g., due to noise or interfering signals) and hypothesizes whether the detected interference is tolerable or precludes current use of the assigned signal in the vicinity of the radio system.

Abstract: Device detection in networks with mixed mobility devices is discussed. Devices in the network first determine a discovery mode from a plurality of discovery modes, wherein the determining is based on a mobility state of the wireless device. The device identifies a set of resources associated with the determined discovery mode, wherein each of the plurality of discovery modes is provisioned with separate resources. A discovery signal is transmitted using the identified set of resources according to the discovery mode. Thus, devices with higher mobility will generally send discovery signals more often than devices that are static or semi-static.

Abstract: Systems, methods, and instrumentalities are disclosed to communicate with subscribers in an information-centric networking environment. A WTRU may store a first path from the WTRU to a first subscriber and a second path from the WTRU to a second subscriber. A message from a topology manager may be received. The message may indicate a change to a network topology. In response to a determination that the change to the network topology relates to the first path and does not relate to the second path, the WTRU may remove the first path from the memory and maintain the second path in the memory. The WTRU may send a request to the topology manager for a third path to replace the first path that was removed from memory. In response to the above determination, a portion of the first path may be removed and replaced according to the above mechanism.
