A network node and a method for the network node determine a physical distancing metric (PDM) associated with at least one wireless device (WD). The network node includes processing circuitry configured to determine a location of each wireless device (WD) of a plurality of WDs and determine the PDM based at least in part on the location of each WD of a subset of WDs of the plurality of WDs and a predetermined threshold, the location of each of WD of the subset of WDs being within a predefined area. Also, a WD and a method for the WD is provided. The WD includes at least a radio interface configured at least to receive a first message including physical distancing information based at least on the transmitted wireless signal.

Physical distancing tracking and notification

Systems and methods related to monitoring a status, or health, of a (e.g., massive) Multiple Input Multiple Output (MIMO) transceiver and, in particular, that of an antenna system (e.g., an Advanced Antenna System (AAS)) of the MIMO transceiver are disclosed. In some embodiments, a method of operation of a radio system implemented in a radio access node to perform supervision of a MIMO transceiver of the radio system comprises performing continuous over-the-air based supervision the MIMO transceiver of the radio system, determining a status of the MIMO transceiver based on results of performing continuous over-the-air based supervision of the MIMO transceiver of the radio system, and taking an action based on the status of the MIMO transceiver.

Massive MIMO AAS supervision

A device for guiding connection installation to communicatively connect a plurality of radio ports of a base station to a plurality of antennas is provided. The device includes a connector configured to communicate with a first radio port of the plurality of radio ports of the base station. The device further includes a receiver in communication with the connector. The receiver is configured to receive first configuration data that is communicated from the first radio port of the plurality of radio ports. The first configuration data indicating a next connection for the first radio port toward one of the plurality of antennas. The device further includes a display and a processor in communication with the receiver and the display. The processor is configured to cause the first configuration data to be displayed on the display.

Device to guide equipment cable installation between radio ports of a base station and multiple antennas

In some embodiments, a node associated with a distributed antenna wireless system obtains one or more combined receive signals responsive to a transmission by the wireless device. The distributed antenna wireless system comprises multiple Remote Radio Heads (RRHs) each comprising one or more receivers. Each receive branch of one or more receive branches of the distributed antenna wireless system comprises a combination of one receiver from each of the RRHs. The one or more combined receive signals comprise, for each receive branch, a combined receive signal that is a combination of signals received by the receivers comprised in the receive branch in accordance with different simultaneous ON/OFF patterns assigned to the RRHs for the receive branches. The node analyzes the one or more combined receive signals to determine information indicative of a geographic location of the wireless device.

Systems and methods for UE positioning in a distributed antenna wireless system

A system is provided. The system includes a plurality of network nodes for operating in a Time Division Duplex, TDD, network. The plurality of network nodes includes at least a network node and a first neighbor network node. The network node includes a node processor and node memory. The node memory contains instructions executable by the node processor. The first network node is configured to detect interference caused by the first neighbor network node in at least one uplink, UL, subframe, and determine a potential reason for the interference caused by the first neighbor network node.
