In accordance with a first aspect of the present disclosure, a communication device is provided, comprising: a receiver configured to receive one or more signals from an external communication device; a classifier configured to classify the external communication device using the signals received by the receiver and to output a corresponding classification result; and a processing unit configured to change one or more configuration settings of the communication device in dependence on the classification result. In accordance with a second aspect of the present disclosure, a corresponding method of operating a communication device is conceived. In accordance with a third aspect of the present disclosure, a corresponding computer program is provided.

The present disclosure provides a method for transmitting a control signal, and a transmission node. The method includes: in a case that the transmission of the first control signal meets a transmission limiting condition of a short control signal, transmitting the first control signal by listen before talk (LBT) of category 1, or transmitting the first control signal after performing channel listening by LBT of category 2.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a configuration signal indicating that the UE supports using a spatial reference signal for a channel performance measurement procedure. The UE may receive an activation signal from the base station activating the spatial reference signal for the channel performance measurement procedure. The UE may perform, based at least in part on the activation signal, the channel performance measurement procedure using the spatial reference signal transmitted by the base station, wherein the channel performance measurement procedure comprises pathloss estimation of a channel. The UE may select, based at least in part on a result of the channel performance measurement procedure, a transmission power for an uplink transmission to the base station. The UE may perform the uplink transmission to the base station based at least in part on the transmission power.

A testing bench can be used while testing wireless telecommunications devices. In some examples, the testing bench includes a first surface and a second surface that houses a patch panel, a combiner, and/or an attenuator. The testing bench can be located in a shielded enclosure with at least two conductive radio frequencies (RF) shield layers separated by an insulator material. In some examples, the testing bench may receive a radio signal from a radio source located outside of the shielded enclosure and provide the radio signal to a wireless (UE) device under testing via the patch panel, the combiner and/or the attenuator.

A base station may transmit, to a user equipment (UE), an indication of parameters (e.g., thresholds) for radio link monitoring (RLM). The UE may monitor active beam pairs in accordance with the indication. In some cases, the UE may configure or may be configured (e.g., by a base station) to transmit reference signals for triggering an RLM operation based on the monitored beam pairs. After triggering, the base station may perform an RLM operation with the UE. Additionally or alternatively, a base station may configure a UE with a beam monitoring configuration that enables uplink beam monitoring. The configuration may indicate one or more active beam pairs for uplink transmissions from the UE, and the base station may perform an RLM operation on the indicated beam pairs. Based on RLM operations (e.g., joint uplink and downlink beam monitoring), beam pairs may be reestablished or newly established.

A communication network comprises a plurality of electronic devices coupled via a plurality of communication links. The communication links comprise links over a first physical medium and links over a second physical medium. A method of operating the network comprises issuing, at an originator device, a path request message directed towards a destination device, transmitting the path request message from the originator device to the destination device through a first set of intermediate devices via a forward sequence of links, issuing, at the destination device, a path reply message directed towards the originator device, and transmitting the path reply message from the destination device to the originator device through a second set of intermediate devices via a reverse sequence of links.

Automated radio frequency safety and compliance for 5G network systems. In an embodiment, a database comprises, for each of a plurality of sites, data representing relative locations of transmitter(s), including at least one 5G antenna, that emit radio frequency (RF) radiation at the site. For at least one of the sites, a power density caused by the transmitter(s) is calculated for one or more areas of the site. In addition, a maximum permissible exposure (MPE) map of the site is generated. The MPE map may comprise a graphical representation of each transmitter, and graphically distinguish any area of the site for which the calculated power density exceeds at least one limit.
