Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of interruption time reduction. The method comprises receiving, at a terminal device and from a centralized network device, a configuration at least indicating that a L1 measurement for cell change is to be reported by the terminal device with an indication of interruption free TA acquisition for a cell associated with the cell change, or per a panel indication of the terminal device; and transmitting, to a distributed network device, a report of the L1 measurement based on the configuration.

Abstract: User equipment (UE) may be provided that includes means for: reporting at least one candidate CSI beam index to a network to avoid and/or mitigate a maximum permissible exposure (MPE) event; wherein the user equipment associates at least one candidate antenna of the user equipment to the at least one candidate CSI beam index. An apparatus may also be provided that includes means for: creating a first mapping of antennas to downlink path delay intervals using a wider beam downlink reference signal; creating a second mapping of downlink path delay intervals to downlink spatial filters using different narrower beam reference signals; and controlling the selection of an antenna based on second mapping.

Abstract: An apparatus and method for beam steering is disclosed. The apparatus comprises: a beam forming signal generator configured to generate a beam forming signal for applying to at least one of amplitude and phase shift circuitry associated with an antenna array to provide a radiation pattern. A determining means is provided that is configured to determine a signal strength of interfering signals received at the antenna array within a user equipment and to determine a dominant interfering ratio indicative of a strength of a strongest interfering signal relative to a strength of other interfering signals. A comparator is provided that is configured to compare the dominant interfering ratio to a predetermined ratio value and where the dominant interfering ratio exceeds the predetermined ratio value to generate a control signal for controlling the beam forming signal generator to generate a radiation pattern comprising a beam and at least one steered null.

Abstract: An apparatus comprising: an antenna array comprising a plurality of antenna elements configured for receiving multiple input multiple output (MIMO) signals. The antenna array comprises at least a first subpart of the antenna array comprising a first subsection of the plurality of antenna elements. A second subpart of the antenna array comprises a second subsection of the plurality of antenna elements. An alignment of the antenna elements in the second subpart deviates substantially by 30°-60° from an alignment of the antenna elements in the first subpart.
