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.

A communication method, performed by a data transmission end, and including: performing clear channel assessment (CCA) through an assessment beam, wherein the assessment beam is associated with at least one transmission beam for transmitting data.

A method of wireless communication includes receiving, by a user equipment (UE), a first transmission and transmitting, by the UE, a first measurement report that is based on the first transmission and includes at least a first measurement result. The method further includes receiving, by the UE, a second transmission that includes a demodulation reference signal (DMRS) and further includes transmitting, by the UE, a second measurement report that is based on the DMRS. The second measurement report includes at least a first value that is based on a difference between the first measurement result and a second measurement result that is based on the DMRS.

An apparatus for selecting sidelink resources includes determining processer circuitry configured to determine a first monitoring time period at least according to a service periodicity, a last time unit of a sensing time period and a selection time period, a monitor configured to monitor sidelink control information in the first monitoring time period, and excluding processor circuitry configured to exclude one or more candidate resources in the selection time period according to the received sidelink control information.

Methods for determining variability in a state of a medium, include monitoring the medium and determining the variability in the state of the medium based on the processing of the response over time based on the response detected at the at least one receive element over time. Monitoring the medium can include generating a transmit signal, transmitting it into the medium using a transmit element, and receiving a signal from the medium at a receive element. The transmit and receive elements can be decoupled from one another. The transmit and receive elements can have differing geometry. The determined variability in the state of the medium can be used to provide notifications and/or take automated actions.

Methods, systems, and devices for wireless communication are described. A discontinuous reception (DRX) periodicity may be configured to enable monitoring of a reference signal (RS) for RLM procedures. For example, a transmitting device may configure a DRX periodicity for an RS, where the configured DRX periodicity may include a periodicity of discrete transmissions of the RS or a periodicity of a transmission window in which the RS is located. Accordingly, a receiving device may identify the DRX periodicity and monitor radio link quality using the RS based on the DRX periodicity. In some examples, the RS may be transmitted independent of control channel transmissions, and the transmitting device may configure one or more control resource sets for the RS.

A test system for testing a device under test comprises a testing device and a device under test.
