Abstract: Disclosed is a method that includes measuring a distance to a blockage using a radar functionality of an antenna array, determining, based on the distance, that transmission power is to be limited due to a maximum permissible exposure event, and determining if the distance is greater or shorter than a threshold distance which corresponds to a far-field distance of a radiation pattern used for the radar functionality. Depending upon the distance to the blockage relative to the far-field distance and whether the distance is greater than a minimum distance for obtaining reliable angular directions of the blockage using the radar functionality, the method takes different actions in order to optimize the antenna array configuration for a beam used for uplink transmission to an access node.

Abstract: An apparatus for use by a UE configured to conduct a communication in a communication network. The apparatus is configured to receive and process signals from the communication network via signal receiving portions, wherein one of the signal receiving portions is a serving cell signal receiving portion used for connecting to the communication network via a serving cell, and another of the signal receiving portions is a non-serving cell signal receiving portion being not used for connecting to the communication network. A signal receiving portion specific offset value is obtained for each of the signal receiving portions. Signal quality values for signals received by the signal receiving portions from the communication network are measured, wherein the cells include the serving cell. A measurement report is sent to the communication network on the basis of the results of the signal quality measurements and the offset values for the signal receiving portions.

Abstract: A communication device for use in a cellular network includes a plurality of antenna panels for communication with cells in a cellular network, circuitry for carrying out a panel selection process based on received power level for selecting an antenna panel, and circuitry for performing measurement cycles requiring determination of respective power levels. The circuitry for performing measurement cycles measures a first received power level from said neighbor cell with the antenna panel selected for said neighbor cell and measures a second received power level from said neighbor cell with the antenna panel selected for said serving cell. The circuitry for performing measurement cycles measures a third power level received for said neighbor cell with the antenna panel selected for said serving cell and adjusting said third power level with an offset function, said adjusted third power level being used as the respective power level for said neighbor cell.

Abstract: When a user equipment detects a condition that a distance between the user equipment, which has an established connection with a network entity of a communications network system, and a subject enters apre-warning region, the user equipment enters a monitoring mode based on at least the detected condition. In the monitoring mode, options of operations to be performed by the user equipment to mitigate degradation of the established connection due to a required power backoff of an antenna of the user equipment are monitored.
